Answer: 3 3/4s' carpets

Step-by-step explanation:

Answer:

y= 3x - 5

Step-by-step explanation:

coordinates given: (4,7) & (1, -2)

to find m (slope) = rise/run = (y2-y1) /(x2-x1)

= ( -2-7) / (1 - 4)

= -9/-3

= 3

therefore, y=3x + b

to find b:

taken coordinate: (4,7)

y=3x + b

7=3 (4) + b

7= 12 + b

7-12 = b

-5 = b

(*the value of b will be same even if we take the other coordinate)

therefore, y = 3x -5

Answer:

x = 2

Step-by-step explanation:

(2, 5) and (2, 9)

Ok. First, let's find the slope using the slope formula.

[tex]m = \frac{y2-y1}{x2-x1} =\frac{9-5}{2-2} = 4/0[/tex]

4/0 is undefined.

When the slope is undefined, that means that it's a straight line going down from the x.

So the equation is just x = 2

Answer:

  B.  18 cm²

Step-by-step explanation:

The area of a trapezoid can be found using the formula ...

  A = 1/2(b1 +b2)h

For the given dimensions, the area is ...

  A = 1/2(7 cm +5 cm)(3 cm) = 1/2(12)(3) cm² = 18 cm²

Answer:

C: y + 3 = 1/4(x + 4)

Step-by-step explanation:

Perpendicular to a given line means opposite inverse of the slope...

Equation of line is: y = -4x - 3

slope in above equation is -4, perpendicular would be 1/4

Perpendicular equation of a line through P(-4, -3):

y = mx + b

-3 = 1/4(-4) + b

-3 = -1 + b

b = -2

Use perpendicular slope and the b from above to form the perpendicular equation of line:

y = 1/4x - 2

Check:

(-3) = 1/4(-4) - 2

-3 = -1 - 2

-3 = -3

Answer:

y^60

Step-by-step explanation:

Answer:

The the equation of the line through the points (8, -2) and (5, 5) in slope-intercept form is

Step-by-step explanation:

Let's start by calculation the slope of the line by finding the slope of the segment that joins the two given points (8, -2) and (5,  5):

Now we use this slope in the general slope-intercept form of a line;

and then we calculate the value of the intercept "b" by using one of the given points through which the line must pass (for example (5,5) ), and solving for b:

The the equation of the line is

Step-by-step explanation:

A black bar with 7 copper colored coils around it is the strongest.

Electromagnets are defined as magnet which works through electricity.

We know permanent magnets show magnetic properties every time. We cannot alter it. But electromagnets only acts as a magnet when current passes through it. Otherwise, it is just a coiled wire.

Strength of electromagnet depends on basically two things:

First, the amount of current flowing through the wire and

Second, the number of turns of wire around the coil.

Here there are four electromagnets which are black bar with 5, 2, 7 and 4 copper colored coils around it.

Number of coils is maximum for the black bar with 7 copper colored coils around it, which results in the strongest electromagnet.

Hence, a black bar having 7 copper colored coils around it is the strongest.

Step 1: Simplify both sides of the equation.

[tex]\fbox{9−7y(7)=6+5−3y−416}[/tex]

[tex]\fbox{9+−49y=6+5+−3y+−416}[/tex]

Answer:

$6.44

Step-by-step explanation:

First, we have to find out how many total ounces the pack weighs.

Multiply the number of bars by the oz of each bar.

36 x 1.6 = 57.6

Divide the cost of the pack by the total oz

23.2 ÷ 57.6 = 0.40277... (Let's round it to 0.4028)

Multiply the cost per oz to by 16 (16 oz = 1 lb) to get cost per pound

0.4028 x 16 = 6.4448

Round it to the nearest hundredth, and we get that the price per pound is $6.44.

[tex]x+1\frac{1}{3}=3\frac{2}{3}[/tex]

Step-by-step explanation:

Let the number of cups of onions Katrina still needs to chop = x

She has already chopped the onions = [tex]1\frac{1}{3}[/tex] cups ≈ [tex]\frac{4}{3}[/tex] cups

So total amount of chopped onions = [tex](x+\frac{4}{3})[/tex] cups

Since, onion soup recipe calls for the chopped onions = [tex]3\frac{2}{3}[/tex] cups ≈ [tex]\frac{11}{3}[/tex] cups

Therefore, equation which shows the number of cups of onions to be chopped more will be,

[tex]x+1\frac{1}{3}=3\frac{2}{3}[/tex]

We further solve this equation for the value of x,

x = [tex]\frac{11}{3}-\frac{4}{3}[/tex]

x = [tex]\frac{(11-4)}{3}[/tex]

  = [tex]\frac{7}{3}[/tex] cups

  ≈ [tex]2\frac{1}{3}[/tex] cups
