Step-by-step explanation:

Equation of a line has been given as,

y = -2x + 5

Input-output points lying on the the line are,

x          0          1            2           3

y          5          3            1          -1

Now we can plot these points on the graph and join them to get the line representing the given equation.

Answer:

[tex]Perimeter = \frac{39t-4}{4}[/tex]

Step-by-step explanation:

Given

[tex]Lengths: (2\frac{1}{4}t - 5), (4t + 3), (1/2t - 1), (3t + 2)[/tex]

Required

Determine the perimeter

The perimeter is calculated as the sum of the lengths of the irregular shape.

i.e.

[tex]Perimeter = (2\frac{1}{4}t - 5) + (4t + 3) + (1/2t - 1) + (3t + 2)[/tex]

Remove brackets

[tex]Perimeter = 2\frac{1}{4}t - 5 + 4t + 3 + 1/2t - 1 + 3t + 2[/tex]

Collect Like Terms

[tex]Perimeter = 2\frac{1}{4}t +4t + 1/2t + 3t - 5 + 3 - 1 + 2[/tex]

[tex]Perimeter = 2\frac{1}{4}t +4t + 1/2t + 3t -1[/tex]

Convert mixed number to improper fraction.

[tex]Perimeter = \frac{9}{4}t +4t + 1/2t + 3t -1[/tex]

Take LCM

[tex]Perimeter = \frac{9t + 16t + 2t + 12t}{4} -1[/tex]

[tex]Perimeter = \frac{39t}{4} -1[/tex]

Take LCM

[tex]Perimeter = \frac{39t-4}{4}[/tex]  --- The perimeter of the shape

We want to find the perimeter of the irregular quadrilateral given that we know its lengths. By direct computation, we will get:

P(t) = (39/4)*t - 1

Remember that for any figure, the perimeter is defined as the sum of the lengths of each side.

Here we have that the lengths of the four sides of the quadrilateral are:

(2 1/4t - 5)

(4t + 3)

(1/2t - 1)

(3t + 2)

So we must sum that, we will get:

P = (2 1/4t - 5) + (4t + 3) + (1/2t - 1) + (3t + 2)

Notice that in the first part we have a mixed number, we can rewrite it as:

2 + 1/4 = 8/4 + 1/4 = 9/4

Then the sum is:

P = ((9/4)t - 5) + (4t + 3) + (1/2t - 1) + (3t + 2)

Now we simplify this sum:

P = (9/4 + 4 + 1/2 + 3)*t + (-5 + 3 - 1 + 2)

P = (39/4)*t - 1

So the perimeter, as a function of t, is:

P(t) = (39/4)*t - 1

Answer:

n = 28

Step-by-step explanation:

The angle at the centre is twice the angle on the circle subtended on the same arc, then

35 + m = 0.5 × 98 = 49 ( subtract 35 from both sides )

m = 14

∠ n is at the centre subtended on the same arc as ∠ m , thus

n = 2m = 2 × 14 = 28

Answer:

-8/5

Step-by-step explanation:

y values minus each other over x values minus each other

Answer:

-8/5 or -1.6

Step-by-step explanation:

the formula for slop is y2-y1/x2-x1

y2 is -2

y1 is 6

x2 is 1

x1 is -4

(-2-6)/(1+4)

(-8)/(5)

the slope is -8/5 or -1.6

Answer:

this is the correct solution for your question

Answer:

The value of k is -4.

Step-by-step explanation:

In order to find the value of k, you have to substitite x = -1/2 into the equation :

[tex]2 {x}^{2} - 7x + k = 0[/tex]

[tex]let \: x = - \frac{1}{2} [/tex]

[tex]2 {( - \frac{1}{2} )}^{2} - 7( - \frac{1}{2} ) + k = 0[/tex]

[tex]2( \frac{1}{4} ) + \frac{7}{2} + k = 0[/tex]

[tex] \frac{1}{2} + \frac{7}{2} + k = 0[/tex]

[tex]4 + k = 0[/tex]

[tex]k = - 4[/tex]

Answer:

(f + g)(x) = I2x + 1I + 1 ⇒ C

Step-by-step explanation:

Let us solve the question

∵ f(x) = I2x + 1I + 3

∵ g(x) = -2

→ We need to find (f + g)(x), which means add the two functions

∵ (f + g)(x) = f(x) + g(x)

→ Substitute the right side of each function on the right side

∴ (f + g)(x) = I2x + 1I + 3 + (-2)

→ Remember (+)(-) = (-)

∴ (f + g)(x) = I2x + 1I + 3 - 2

→ Add the like terms in the right side

∵ (f + g)(x) = I2x + 1I + (3 - 2)

∴ (f + g)(x) = I2x + 1I + 1

Answer:

The equation of the line is y = 2x - 5 ⇒ D

Step-by-step explanation:

The form of the linear equation is y = m x + b, where

Note: To prove that a line passes through a given point, substitute x in the equation of the line by the x-coordinate of the point and solve to find y, if y equals the y-coordinate of the point, then the line passes through it

∵ The slope of the line is 2

∵ The line passes through the point (3, 1)

→ Find at first which equation has slope 2, then check if the line passes

  through the point or not using the note above

A.

∵ y = 2x + 5

→ By comparing it with the form of the equation above

∴ m = 2

∴ The line has the same slope

→ Substitute x by 3 to find y

∵ y = 2(3) + 5 = 6 + 5 = 11

∵ y-coordinate of the point = 1

∴ The line does not pass through the point

B.

∵ y = 2x + 1

→ By comparing it with the form of the equation above

∴ m = 2

∴ The line has the same slope

→ Substitute x by 3 to find y

∵ y = 2(3) + 1 = 6 + 1 = 7

∵ y-coordinate of the point = 1

∴ The line does not pass through the point

C.

∵ y = 2x - 1

→ By comparing it with the form of the equation above

∴ m = 2

∴ The line has the same slope

→ Substitute x by 3 to find y

∵ y = 2(3) - 1 = 6 - 1 = 5

∵ y-coordinate of the point = 1

∴ The line does not pass through the point

D.

∵ y = 2x - 5

→ By comparing it with the form of the equation above

∴ m = 2

∴ The line has the same slope

→ Substitute x by 3 to find y

∵ y = 2(3) - 5 = 6 - 5 = 1

∵ y-coordinate of the point = 1

∴ The line passes through the point

∴ The equation of the line is y = 2x - 5

Answer: (-∞, 3.5)

Step-by-step explanation:

Here we can use the relation:

Exp( Log(X)) = X

Now, we start with the equation:

log(x + 7) > log(3x)

Now we can apply the exponential function to both sides of the inequality to get:

Exp(log(x + 7)) > Exp(log(3x))

x + 7 > 3x

7 > 3x - x

7 > 2x

7/2 > x

3.5 > x

Then the solutions will be all the values of x smaller than 3.5, this set can be written as:

Answer:

D. 2787.64 yd^3

Step-by-step explanation:

This is the formula for the volume of a cone:

[tex]V=\frac{1}{3} \pi r^2h[/tex]

The height of the cone is 22 yd. The radius of the base of the cone is not given but we can use the diameter to calculate it since the radius is equal to half of the diameter.

[tex]r=\frac{1}{2}d\\r=\frac{1}{2}(22)\\r=11yd[/tex]

Therefore, the radius of the base of the cone is 11 yd.

Now, we plug our values into the formula and solve.

[tex]V=\frac{1}{3} \pi r^2h\\V=\frac{1}{3} \pi (11^2)(22)\\V=\frac{1}{3} \pi (121)(22)\\V=\frac{1}{3} \pi (2662)\\V=\frac{1}{3} \pi (2662)\\V=2787.64 yd^3[/tex]

Therefore, the volume of the cone is equal to 2787.64 yd^3.

Answer:

debt-to-income ratio= 0.7125

Step-by-step explanation:

Giving the following information:

Monthly expenses= $2,850

Monthly income= $4,000

To calculate the debt-to-income ratio, we need to use the following formula:

debt-to-income ratio= monthly debt payment / gross monthly income

debt-to-income ratio= 2,850/4,000

debt-to-income ratio= 0.7125

As a percentage:

debt-to-income= 0.7125*100

debt-to-income= 71.25%

The debt-to-income ratio is the percentage of your income dedicated to paying your debts.

The strategy is to find the x and y intercept of the given equation

Step-by-step explanation:

4x+3y≥12

In order to determine where the boundary line, we need to first get the x and y-intercept of the inequality expression given;

x-intercept occurs at where y = 0

when y  = 0

4x + 3(0)≥12

4x ≥12

x ≥12/4

x≥ 3

Also y intercept occurs at where x = 0

4x+3y≥12

4(0)+ 3y ≥12

3y≥12

y≥12/3

y≥4

Hence the intercept of the line is at (3, 4). A thick line will pass through this point and the upper part of the graph will be shaded. The strategy is to find the x and y intercept of the given equation
