Which equation represents a line with a slope of -8 and
a y-intercept of 4?
A y = -8x+4
B y = -4x+8
C y = - 8x-4
D y = 8x+4

Answers

Answer 1

Answer: A. y = -8x + 4 because the slope goes in front with the x (-8x) and the y intercept is after the slope (4)

Write the slope-intercept form of the equation for each line.

Answers

Step-by-step explanation:

First, let's find the slope of the line. Note that it passes through P1(-8, -1) and P2(0, -5). So the slope of this line is

[tex]m = \dfrac{y_2 - y_1}{x_2 - x_1} = \dfrac{-5 - (-1)}{0 - (-8)}[/tex]

[tex]\:\:\:\:\:= \dfrac{-4}{8} = -\dfrac{1}{2}[/tex]

The slope-intercept form of the equation can be written as

[tex]y = mx + b = -\frac{1}{2}x + b[/tex]

To solve for b, we can use either P1 or P2. Let's use P2.

[tex]-5 = -\frac{1}{2}(0) + b \Rightarrow b = -5[/tex]

Therefore, the slope-intercept form of the equation for the line is given by

[tex]y = -\frac{1}{2}x - 5[/tex]

Homer Simpson finds himself in a panic attempting to meet the April 15th tax deadline. If Homer and his wife have an income of $60,000, earned $1200 in interest, invested $2500 in a tax-deferred savings plan, and have a total of $12,000 in exemptions and deductions, what would be his taxable income?

Answers

Answer:

As given, Income of Homer and his wife = $60000

Interest earned = $1200.

Adding this to total income, we have total taxable amount = 60000+1200 = $61200

Now, investment in tax deferred savings plan = $ 2500

This amount will be subtracted from total taxable income, so amount becomes = 61200-2500 = $58700

We will also subtract the exemptions and deductions = $12000

Amount becomes = 58700-12000 = $46700

Hence, Net taxable income is $46,700

Luis rents a 17-foot moving truck for 3 days. The rate for the truck is $60 for the
first day and $21.95 for each day after that. He also has to pay $0.79 per mile for
every mile over 50 miles. Luis also purchases insurance which cost him $20. If Luis
drives 200 miles before he returns the truck, how much will he pay?
$242.40
$204.35
$222.40
$281.90.

Answers

Answer:

Luis will pay $242.40

Step-by-step explanation:

60.00(1st day)+21.95(2nd day)+21.95(3rd day)+20.00(Insurance)=123.90

200 (mi driven) - 50 (mi allowed)= 150 miles must be paid for

150*0.79(rate per mile)=118.50

123.90+118.50=$242.40 Total Cost

If the area of this rectangle is 30cm square what would the missing side be?

Answers

The area of a rectangle is calculated with this formula: Area = Length • Width. Given the area of the rectangle, we can substitute it in for “A” (area) in the formula, so that we can solve for the missing width value.

A = L • W [Area if Rectangle Formula]

A = 30cm^2 [Given]

(30) = (6) • W [Substitution Property of

Equality]

30 / 6 = 6 • W / 6 [Division Property of

Equality]

5 = W [Definition of Equality]

W = 5 [Symmetric P.O.E]

Therefore, the width of this rectangle is 5.
We can check this because A = 6 • 5 = 30cm^2

A poster is 1 3/5 feet wide and 3 1/8 feet long. What is the area of the poster?

Answers

Answer:

5 feet squared.

Step-by-step explanation:

You can multiply the length by the width to get the total area of the poster.

1 3/5 x 3 1/8 is equal to 5, therefore, the area of the poster is 5 feet squared.

Answer: 5 ft^2

Step-by-step explanation:

Area=length times width. In this problem, the lenght is 3 1/8 and the width is 1 3/5. We have to multiply these two:

1 3/5*3 1/8= 8/5*25/8=5.

So the area is 5 ft^2.

-7.2x < -50.4x + 432

Answers

Answer:

x<10

Step-by-step explanation:

We can start off with adding 50.4x to both sides:

Once we do that we get the following: 43.2x < 432

If you notice, they both are almost the same number with the different of the decimal place. Lets multiply both sides by 10 to get rid of the decimal place:

432x < 4320

Now, if you see, they're basically the same number but the second place is x10 greater.

We can divide both sides by 432 and get x<10 as our answer!

6. What number can be added to -4 to get a sum of 0?
a) -4
b) 0
c) %
d) 4

Answers

-4 + x = 0

Add 4 to both sides:

x = 4

The answer is d) 4

Answer:

Let the required number be ' x '

Therefore, according to the given problem

[tex]x + (- 4 )= 0 \\ x - 4 = 0 \\ \boxed{x = 4}[/tex]

Hence, 4 should be added to -4 to get the sum of 0

d) 4 is the right answer.

The graph of y = x2 –7x +12 is a parabola with x-intercepts at and a vertex that is the
point on the curve.

Answers

The vertex of the parabola is at the point (3.5, 0.75).

To find the x-intercepts of the given quadratic equation [tex]y = x^2 - 7x + 12,[/tex]we set y = 0 and solve for x.

[tex]0 = x^2 - 7x + 12[/tex]

Factoring the quadratic equation, we can rewrite it as:

0 = (x - 3)(x - 4)

Setting each factor equal to zero, we find the x-intercepts:

x - 3 = 0 => x = 3

x - 4 = 0 => x = 4

Therefore, the parabola represented by the equation [tex]y = x^2 - 7x + 12[/tex] has x-intercepts at x = 3 and x = 4.

To find the vertex of the parabola, we can use the formula:

x = -b / (2a)

In this case, a = 1 (coefficient of [tex]x^2[/tex]) and b = -7 (coefficient of x). Plugging these values into the formula, we get:

x = -(-7) / (2[tex]\times[/tex] 1)

x = 7 / 2

x = 3.5

To find the y-coordinate of the vertex, we substitute this value back into the original equation:

[tex]y = (3.5)^2 - 7(3.5) + 12[/tex]

y = 12.25 - 24.5 + 12

y = 0.75

Therefore, the vertex of the parabola is at the point (3.5, 0.75).

In summary, the graph of the equation [tex]y = x^2 - 7x + 12[/tex]is a parabola with x-intercepts at x = 3 and x = 4. The vertex of the parabola is located at the point (3.5, 0.75).
