Answer:
D.) 5x - 2y = 2
Step-by-step explanation:
1. Find all of the options and convert them to slope-intercept form by isolating y. If you isolate y on all of them, you should get that A is y =-2/5x - 1, B is y = 2/5x - 1, C is y = -5/2x - 1, and D is y = 5/2x - 1.
2. Use logic. This line cannot be negative, because negative lines go up to down, not down to up. That cancels out the possibility of A.) and C.) being answers. Now, we know that the slope has to be more than 1 because it is more compressed than that of a line with a slope of 1. The only slope that is more than 1 is D, so that makes D the answer (If you didn't understand this step, go to step 3).
3. Find the slope (This step does not need to be done if you understood Step 2). Take 2 points to be able to find the slope. Two random points on this line are (2,4) and (0,-1). Next, plug them into the formula to find slope. 4-(-1)/2-0 = 5/2, so the slope is 5/2. The only equation with a slope of 5/2 is D. D is the answer.
Answer: D.) 5x - 2y = 2

Answer:
The person's height must be greater than or equal to 55 inches to go on the ride
Step-by-step explanation:
Let
x -----> the height of the person
we know that
A person must be at least 55 inches tall to go on the carnival ride
The phrase " at least" means "greater than or equal to"
so
The inequality that represent this situation is
![x\geq 55\ in](https://tex.z-dn.net/?f=x%5Cgeq%2055%5C%20in)
therefore
The person's height must be greater than or equal to 55 inches to go on the ride
Answer:
perimeter = 8x+12
Step-by-step explanation:
perimeter of a rectangle = 2(Length + width)
= 2[(3x+5)+(x+1)]
=2( 3x+5+x+1)
=2(4x+6)
perimeter= 8x+12
First, you find the brother's age by dividing mary's age by 4.
16 ÷ 4 = 4
Now that you have two ages, you can just make a list to find the answer.
16 and 4
18 and 6
20 and 8
22 and 10
24 and 12
