There is a given point (10,3) this shows that when the width (X) is 10, the height (Y) is 3.

On the left side of the graph, they show an equation for the height Hw as being the constant over w ( width).

Using the given point solve for the constant.

Replace Hw with 3 and w with 10:

3 = Constant/10

Solve for the constant by multiplying both sides by 10:

Constant = 3 x 10

Constant = 30

The answer is B.

Help please! It's a quiz. will mark brainliest for correct answer!

Answer:

you first start by making your equation: 45 +.25x = 70 +.15x. then subtract .15x from both sides. it should look like 45 +.10x = 70. subtract 45 from both sides then you get .10x = 25. divide 10 to both sides and you get 250. so the two companies will be the same at 250 texts.

Simplify the following expression.

Rzqust [24]

Step-by-step explanation:

Step 1: Add the numbers: 9.5 +6.2 = 15.7

$=8.6\left(15.7-3.5^2\right)$

$3.5^2=12.25$

$=8.6\left(15.7-12.25\right)$

Step 2: Subtract the numbers: 15.7 - 12.25 = 3.45

$= 3.45X 8.6$

Step 3: Multiply the numbers: 8.6 × 3.45 = 29.67

$=29.67$

- To solve this equation, the first step is to add the numbers 9.5 + 6.2 into the equation and it will lead to 15.7 as the number for step one.

- To solve this equation, the second step is to subtract the numbers 15.7 - 12.25 into the equation and it will lead to 3.45 as the answer.

- To solve this equation, the third step is to multiply the numbers 8.6 x 3.45 into the equation and it will lead 29.67 as the final answer for the whole equation.

Answer:

$=29.67$

Hope this helps.

Answer:

$-10+i\sqrt{2}$

Step-by-step explanation:

One is given the following expression:

$\sqrt{4}-\sqrt{-98}-\sqrt{144}+\sqrt{-128}$

In order to simplify and solve this problem, one must keep the following points in mind: the square root function ( $\sqrt{}$ ) is a way of requesting one to find what number times itself equals the number underneath the radical sign. One must also remember the function of taking the square root of a negative number. Remember the following property: ( $\sqrt{-1}=i$ ). Simplify the given equation. Factor each of the terms and rewrite the equation. Use the square root property to simplify the radicals and perform operations between them.

$\sqrt{4}-\sqrt{-98}-\sqrt{144}+\sqrt{-128}$

$\sqrt{2*2}-\sqrt{-1*2*7*7}-\sqrt{12*12}+\sqrt{-1*2*8*8}$

Take factors from out of under the radical:

$\sqrt{2*2}-\sqrt{-1*2*7*7}-\sqrt{12*12}+\sqrt{-1*2*8*8}$

$2-7i\sqrt{2}-12+8i\sqrt{2}$

Simplify,

$-10+i\sqrt{2}$

Write an equation for the perimeter of the rectangle

jeka94

Answer:

Area = 2(5x - 4) + 2(5x)

Step-by-step explanation:

Perimeter is the sum of twice the width and twice the length of the rectangle. And since the question is asking us for an equation, we need to write, Area = 2(5x - 4) + 2(5x). When you are required to find the value of x with a given area, just plug that area into the equation, distribute, and simplify to get x.
