Answer:

Place "SUM" at 4 on the number line.

Step-by-step explanation:

8 + (-4) = 8 - 4 = 4

Adding a negative number is the same as subtracting its opposite. Adding -4 is the same as subtracting 4.

Answer:

The answer is 4.

Step-by-step explanation:

Given problem,

8 + (-4)

Since, in the number line the numbers left to zero are negative and right to zero are positive,

When, we move towards a negative number then we move left side while when we move towards a positive number then we move right side,

Thus, the steps involve in the given problem are follow,

Step 1 : Find 8 on the number line,

Step : we have -4, means we need to move left side 4 unit from 8,

Step 3 : the final position is 4.

Hence, 8 + (-4) = 4

Help please, I'm stuck on this :/

Do you have a calculator? you can solve it by substituting x.

y=16x^2

0: y = 16(0)^2 = 16(0) = 0

(x = 0 , y = 0)

0.5: y = 16(0.5)^2 = 16(0.25) = 4

(x = 0.5 , y = 4)

1: y = 16(1)^2 = 16(1) = 16

(x = 1 , y = 16)

1.5: y = 16(1.5)^2 = 16(2.25) = 36

(x = 1.5 , y = 36)

2: y = 16(2)^2 = 16(4) = 64

(x = 2 , y = 64)

2.5: y = 16(2.5)^2 = 16(6.25) = 100

(x = 2.5 , y = 100)

3 : y = 16(3)^2 = 16(9) = 144

(x = 3 , y = 144)

4: y = 16(4)^2 = 16(16) = 256

(x = 4 , y = 256)

if you multiply a negative number by itself, it will become positive. So, -4, -3, -2.5, -2, -1.5, -1, -0.5 will be the same as the positive 4, 3, 2.5, 2, 1.5, 1, 0.5.

I'm not sure about the pattern, but if you graph it, it'll be symmetrical across the y-axis.

△ACD∼△BED What is the value of x?

slega [8]

Answer:

C. 5

Step-by-step explanation:

Triangle BED is enlarged by scale factor 4.

(25-x)/4 = x

Multiply both sides by 4.

25-x = 4x

Add x on both sides.

25 = 5x

Divide both sides by 5.

5 = x
