The better deal among the options is 9 dollars per pound.

Joe´s mother is deciding whether or not she should buy a 14- ounce package of coffee on sale for $8.50. She also knows she can buy the same coffee for $9.00 per pound.

Therefore, let's find the better deal.

We have to convert the weight to the same units.

1 ounce = 0.0625 pounds

14 ounces = ?

cross multiply

mass = 0.0625 × 14 = 0.875

Therefore, one deal is 0.875 pounds for $8.50 and the other is 9 dollars per pounds.

Hence,

price per pounds = 8.50 / 0.875 = 9.7 dollars per pounds

Therefore, the better deal is 9 dollars per pounds.

Application. Since its inception, area has been the foundation of geometry.

Here,

Our calculation of w = 56 reveals that the parallelogram is 56 yards long.

We can simplify the calculation by altering w to 56 in order to obtain the length of the rectangle but since width is the same as 2w + 6 already.

The rectangle is depicted as having a length of 118 yards.

Accordingly, the playing field measures 118 yards by 56 yards.

Therefore, the size of the game field—118 yards x 56 yards—is the solution to the current problem.

Answer: The function y = 5/x is a reciprocal function, which means the graph of the function will be a hyperbola.

The error the student made could be in the following ways:

The student might have plotted the graph as a straight line instead of a hyperbola

The student might have neglected to reflect the graph across the y-axis, since the function is not defined for x = 0

The student might have not plotted the asymptotes of the graph. The graph will have vertical asymptotes at x = 0 and x = infinity.

To correct the error, the student should plot the graph as a hyperbola with vertical asymptotes at x = 0 and x = infinity. And also reflect the graph across the y-axis.

In case of any further doubts student should check with their teacher or a math reference book.

Solving the provided question, we cans say that by quadratic equation, the age where a person's systolic pressure is 127.54 mm Hg is 46

A quadratic equation is x ax2+bx+c=0, which is a quadratic polynomial in a single variable. a 0. The Fundamental Theorem of Algebra ensures that it has at least one solution since this polynomial is of second order. Solutions may be simple or complicated. An equation that is quadratic is a quadratic equation. This indicates that it has at least one word that has to be squared.

systolic pressure for a person of age 45 years, just plug in y = 45:

systolic pressure is 127.54 mm Hg, plug in P = 127.54

P = 0.004y2 - 0.02y + 120

127.54 = 0.004y2 - 0.02y + 120

0 = 0.004y2 - 0.02y - 7.54

Use the quadratic formula to solve this. The quadratic formula (for ay2 + by + c = 0) is:

y = [-b ± √(b2 - 4ac)]/(2a)

In this case a = 0.004, b = - 0.02 and c = - 7.54 so:

[tex]y = [-b + \sqrt{(b2 - 4ac)]/(2a)}\\y = [-(-0.02) +\sqrt{((0.02)2 - 4(0.004)(-7.54))]/(2(0.004))}\\y = [0.02 + \sqrt{(0.0004 + 0.12064)]/0.008}\\y = [0.02 + \sqrt{0.12104]/0.008}\\y = [0.02+ 0.3479]/0.008\\ y = [0.02 + 0.3479]/0.008 or y = 0.3679/0.008 = 45.989\\ y = [0.02 - 0.3479]/0.008 or y = -0.3279/0.008 = -40.989\\[/tex]

Since -40.988 makes no sense (40.989 years before birth), we throw that answer out.

Answer: The y-intercept for part A is 2 and for part B is -5 and the slope for part A is 3 and for part B is 2. ✅

Step-by-step explanation:

PLEASEEEE GIVE BRANLIEST

The y-intercept is a point on the graph where the line of the function crosses the y-axis. It is represented by the number that is next to the y in the equation of a line (y = mx + b).

The slope is the steepness of the line and it is represented by the number that is next to the x (y = mx + b).

In part A, the y-intercept is 2 and the slope is 3. This means that the line starts at the point (0,2) and for every 1 unit on the x-axis, it goes up 3 units on the y-axis.

In part B, the y-intercept is -5 and the slope is 2. This means that the line starts at the point (0,-5) and for every 1 unit on the x-axis, it goes up 2 units on the y-axis.

So the difference between part A and part B is that the y-intercept for part A is 2 and for part B is -5 and the slope for part A is 3 and for part B is 2. This means that the line in part A starts at a different point and is steeper than the line in part B.

Answer:

In the context of a linear function, the y-intercept is the point where the line crosses the y-axis and the slope is the rate at which the line increases or decreases as the x-value increases. If two functions have different y-intercepts, it means that they have different starting points on the y-axis. Similarly, if two functions have different slopes, it means that they have a different rate of change. So, in part A and part B, if the y-intercept and the slope of the function in part A are different from the y-intercept and the slope of the function in part B, it means that the two functions have a different starting point on the y-axis and a different rate of change respectively.

Step-by-step explanation:

In the context of a linear function, a line can be represented by the equation y = mx + b, where m is the slope and b is the y-intercept.

The y-intercept is the point where the line crosses the y-axis. It is represented by the value of b in the equation y = mx + b. For example, if the equation of the line is y = 2x + 3, the y-intercept is (0,3).

The slope of the line is the rate at which the line increases or decreases as the x-value increases. It is represented by the value of m in the equation y = mx + b. For example, if the equation of the line is y = 2x + 3, the slope is 2.

If the y-intercept and the slope of the function in part A are different from the y-intercept and the slope of the function in part B, it means that the two functions have different starting points on the y-axis and a different rate of change respectively.

For example, if the equation of the function in part A is y = 2x + 3, the y-intercept is (0,3) and the slope is 2. And if the equation of the function in part B is y = 4x + 1, the y-intercept is (0,1) and the slope is 4. Therefore, the y-intercept and slope of part A are different from the y-intercept and slope of part B.

Step-by-step explanation: Start by saying the question out loud in a different format:

60% of what is $54?

We know that of means multiplication and is means equals. This helps us create the equation:

60% x what= $54

Then, we need to make 60% a number we can work with by changing it into a decimal: 0.6. We also need to make 'what' something easier to use as well, so we will use x in place of what:

0.6x=54

Then, get x by itself, which is also called isolating the variable. You do this by dividing by 0.6 on both sides, which is known as using inverse operations.

You should get x=90.

This means that $54 is 60% of $90 and $90 is Noah's goal.

Step-by-step explanation:

Slope:

Take two points and put it in for m=y2-y1/x2-x1

we can use (0,-4) and (3,1)

m=1--4/3-0

m=5/3

m=1.67

Then we use m in y intercept and use the first point as b

y = mx + b

y=1.67x+b

-4 = 1.67(0) + b

-4 = 0 + b

-4 = b

b = -4

y = 1.67x + -4

Y intercept: y = 1.67x + -4

Slope: 5/3

Answer:

y - (-2) = -5/3 (x-6)

Step-by-step explanation:

Using Slope Point Formula (y-y1=m(x-x1) we can use the given slope, and the given coordinate to fill in the equation.

So y1 would be -2 because we only have 1 coordinate, and -2 is the y value. So we have y-(-2)=m(x-x1)

Now we have the slope which is m. The slope is -5/3, so we plug that into m. So now we have y-(-2)=-5/2(x-x1).

Last we plug in x1 to the equation which is 6. So to finish the equation we have y-(-2)=-5/3(x-6).

Answer: X = 88, Y = 26, Z = 11.2

Step-by-step explanation:

First thing is use any linear pair equation that only has one variable.

1. 2x-30 + 34 = 180, Y = 88

Plug in the value of X to a two-variable equation to find the value of y.

2. 2y +88 + 40 = 180, Y = 26

Lastly repeat this step for finding the value of z.

3. 88 + 39 + 5z - 3 = 180, Z = 11.2

Answer: x = 88, y = 26, z = 26

Step-by-step explanation:

The shape shown in the picture is a heptagon.

Sum of interior angle = 900 degrees

Add all the interior angles

x+40+x+22+142+x+39+133+2x-30+114

=5x+460

5x+460=900

5x = 440

x = 88

2y is the exterior angle of x+40

to get 2y, you need to subtract x+40 from 180.

x = 88,

x+40 = 128

2y = 180-128 = 52

y = 26

5z-3 is the exterior angle of x+39

same thing for 5z-3

x = 88,

x+39 = 127

5z-3 = 127

5z = 130

z = 26
