Answer:

2 is y - intercept of the line

Step-by-step explanation:

A LINE HAS AN EQUATION 2 x +4 y = 8, the y - intercept of the line is as:

2 x +4 y = 8 ,
4 y = 8 - 2 x,
y = 8 - 2 x / 4,
y = ( 8 / 4 ) - ( 2 x / 4 ),
y = 2 - 1 / 2 x

Therefore, as we know that equation is y = a + b x, a is y - intercept so 2 is y - intercept.

pentagon [3]

Answer:

A. 5s+2

B. 8s+8

C. 75

D. 27

Step-by-step explanation:

Is difficult to read the exact expressions. If a mistake is present then fix the number and use the same method.

A. The perimeter of the square is all 4 equal sides added together. The length of a side is $\frac{5s+2}{4}$ . Since there are four sides then:

$P= \frac{5s+2}{4}+\frac{5s+2}{4}+\frac{5s+2}{4}+\frac{5s+2}{4} = 5s+2$

Adding 1/4+1/4+1/4+1/4=1. This applies here leaving 5s+2 as the answer.

B. The perimeter of the rectangle is all four sides added together. A rectangle has two pairs of equal side so P = 2l+2w.

$P = 2(s+9) + 2(3s-5)\\P = 2s+18 +6s-10\\P=8s+8$

C. If s=5 then the sum of the two perimeters is:

5s+2+8s+8

5(5)+2+8(5)+8

25+2+40+8

D. Subtract the two perimeters by computing s=7:

8s+8 -(5s+2)

8s+8-5s-2

8(7)+8-5(7)-2

56+8-35-2

64-35-2

29-2

Anton [14]

Answer: Use Fractions and Multiplication.

Step-by-step explanation:

To start, you need to find 1/6 of 12. The easiest way to do this is to multiply 12/1 by 1/6. The answer is 12/6, which simplifies to 2. Then, you do the same for 2/3: 12/1*2/3=24/3, which simplifies to 8. You then add the results to figure out how much has been eaten. 8+2=10

The side length of a square is x+1. write an expression that is equivalent to the perimeter of the square.

Amiraneli [1.4K]

4x + 4

This is because there are four sides of a square, and each side is x + 1.

x + 1 + x + 1 + x +1 + x + 1 = 4x + 4
