Answer:

4x + 5y = 35.

Step-by-step explanation:

Slope intercept form is:

y = m + c

Here m = -4/5 and c = 7, so:

y = -4/5 x + 7

Multiply through by 5:

5y = -4x + 35

4x + 5y = 35 (answer).

y intercept=b=7
Slope=m=-4/5

Equation of the line

$\\ \sf\longmapsto y=mx+b$

$\\ \sf\longmapsto y=\dfrac{-4}{5}x+7$

C=a+8 the variable A represents the number of events attended, and the variable C represents the total cost. What is the total c

Nitella [24]

If a is the number of events, then a = 1. Plugging in 1 for a in the equation $C=a+8$ , you get $C=1+8=9$ .

Total cost is $9.

Wayne is using a waterproof covering to cover a storage locker that measures 4 ft wide, 10 ft tall, and 6 ft long. Which is the

Margaret [11]

Given the dimensions of locker box are length = 6 feet, width = 4 feet, and height = 10 feet.

Wayne wants to cover the box, so we need to find its total surface area. The box is in the shape of rectangular prism.

We know the formula for total surface area of rectangular prism is given as follows :-

$Total \;Surface \;Area = 2*(lw + wh + hl)$

T.S.A. = 2·(6 x 4 + 4 x 10 + 10 x 6) = 2·(24 + 40 + 60) = 2·(124) = 248 feet²

Surface Area = 248 squared feet

To cover the locker with waterproof covering, we needed to find the surface area of the box. As we multiplied two dimensions at a time in the formula, so the units are "squared feet".

Hence, option A is correct i.e. squared feet or ft².

What is the interval notation for the compound inequality? x is less than or equal to -4 or x is greater than or equal to 5?

Tems11 [23]

x is less than or equal to -4 or x is greater than or equal to 5

x <= -4 or x>= 5

There is no intersection of both inequalities when we graph it in number line So, we write the interval notation separately for each inequality

for x<=-4 , x starts at -4 and goes to -infinity because we have less than symbol. Also we have = sign so we use square brackets

Interval notation is (-∞ , -4]

for x>= 5 , x starts at 5 and goes to infinity because we have greater than symbol. Also we have = sign so we use square bracket at 5

Interval notation is [5 , ∞)

Now combine both notation by a 'U' symbol Union

(-∞ , -4] U [5 , ∞)
