(0,-9);slope=4

1 answer:

8 0

1. y=4x-9
2. y=-3x+1
3. y=x-3
4. y=5x-11
5. y=5/6x-3
6. y=-2x+6

I’m not sure how to explain this but basically, if you have y=mx+b (the answer), the equation used to find that is y-y1=b(x-x1). b=slope

It’s kind of confusing but I’ll use the first question as an example.

So, y+9=4(x-0) You would substitute in your x, y, and slope and solve it from there. It’s a bit confusing at first but once you understand it’s easy.

Part B if the height of each prism is 10 Cm what is the surface area prism

Evgen [1.6K]

Answer:

Prism A:

$Area = 288cm^2$

Prism B:

$Area =250cm^2$

Step-by-step explanation:

Given

See attachment for prisms

$Height(h) = 10cm$

Required

Determine the surface area of both prisms

Prism A is triangular and as such, the surface area is:

$Area = 2 * A_b + (a + b + c) * h$

Where

$A_b = \sqrt{s * (s - a) * (s -b) * (s - c)}$

and

$s = \frac{a + b + c}{2}$

Such that a, b and c are the lengths of the triangular sides of the prism.

From the attachment;

$a = 8; b =6; c =10$

So, we have:

$s = \frac{a + b + c}{2}$

$s = \frac{8 + 6 + 10}{2}$

$s = \frac{24}{2}$

$s = 12$

Also:

$A_b = \sqrt{s * (s - a) * (s -b) * (s - c)}$

$A_b = \sqrt{12 * (12 - 8) * (12 - 6) * (12 - 10)}$

$A_b = \sqrt{576}$

$A_b = 24$

So:

$Area = 2 * A_b + (a + b + c) * h$

$Area = 2 * 24 + (8 + 6 + 10) * 10$

$Area = 288cm^2$

Prism B is a rectangular prism. So, the area is calculated as:

$Area = 2 * (ab + bh + ah)$

From the attachment

$a = b = 5$

$h =10$

So:

$Area =2 * (5 * 5 + 5 * 10 + 5 * 10)$

$Area =250cm^2$

Help me ASAP

KonstantinChe [14]

2 * 4 = 8

8 < 11 is true

2 * 5 = 10

10 < 11 is true

2 * 5.3 = 10.6

10.6 < 11 is true

2 * 5.7 = 11.4

11.4 < 11 is NOT true.

x = 5.7 is not a solution.

Which of the following describes the “p/2” in the expression above?

julia-pushkina [17]

Option B. Quotient is the right answer

Step-by-step explanation:

Given expression is:

p/2 +4(7+p)

Let us look at the options one by one

<u>A. factor</u>

p/2 is not a factor as the factor is always multiplied with another factor

<u>B. quotient</u>

This is the right answer as p is being divided by 2. The quotient of both will be used for further calculations

Hence,

Option B. Quotient is the right answer
