Answer:

x ≤ - 3

Option A

Step-by-step explanation:

Given the inequality :

-7x - 13 ≥ 8

Add 13 to both. Sides

-7x - 13 + 13 ≥ 8 + 13

-7x ≥ 21

Divide both sides by -7

x ≤ - 3

Answer:

Step-by-step explanation:

Part A. John will not be painting the floor area of that of the door or window openings.

Part B. Subtracting the areas of the floor, door, and window from the total surface area will provide the area to be painted so Judy is correct.

Part C.

We first need to find the area to be painted.

A=floor+2(wall1)+2(wall2)-window-door

A=14(7)+2(7)8+2(14)8-3(6)-3(7)

A=98+112+224-18-21

A=395 ft^2

Since a gallon of paint will cover 350 ft^2

395ft^2(gal/350ft^2)=1.13 gal

John will need approximately 1.13 gallons of paint. (Rounded to nearest hundredth of a gallon)

Pls help Whats the equation?
SVETLANKA909090 [29]

Answer: y = -5x + 6

Step-by-step explanation:

First, we need to find the slope, which would be m in the equation. To find m, we can use the formula called "rise over run". Here's the formula: m=\frac{y2-y1}{x2-x1}

So, to use this formula, you pick two points from the line that you're given and solve for m.

Let's use the points (1,1) and (0,6). x1 would be 1, x2 would be 0, y1 would be 1, y2 would be 6

m=\frac{y2-y1}{x2-x1}

m=\frac{6-1}{0-1}

m=\frac{5}{-1}

m=-5    So, the slope is -5

Then, we need to find the y intercept, which would be b in the formula.

We can see that the point where the line meets the y axis is at (0.6), so the y intercept would be 6.

Now let's put everything together:

y = mx+b

y = -5x + 6

What is the smallest positive integer, other than $1$, that is both a perfect cube and a perfect fourth power?
cupoosta [38]
<span>There are two approaches to translate this inquiry, to be specific:
    You need to know a number which can go about as the ideal square root and also the ideal block root.
    You need to know a number which is an ideal square and in addition an ideal 3D shape of a whole number.
    In the primary case, the arrangement is straightforward. Any non-negative whole number is an ideal square root and in addition a flawless solid shape foundation of a bigger number.
    A non-negative whole number, say 0, is the ideal square foundation of 0 and additionally an immaculate shape base of 0. This remains constant for all non-negative numbers starting from 0 i.e. 0, 1, 2, 3, 4, 5, 6, 7, 8, 9
    In the second case as well, the arrangement is straightforward however it involves a more legitimate approach than the primary choice.
    A flawless square is a number which contains prime variables having powers which are a different of 2. So also, a flawless block is a number which includes prime variables having powers which are a numerous of 3. Any number which includes prime components having powers which are a various of 6 will be the answer for your inquiry; a case of which would be 64 which is the ideal square of 8 and an ideal 3D shape of 4. For this situation, the number 64 can be spoken to as prime variables (i.e. 2^6) having powers (i.e. 6) which are a different of 6.</span>
