Answer:
X-int: (1/2 , 0) . Y-int: (0 , 4)
Step-by-step explanation:
FOR X
To find the x-intercept, substitute in 0 for Y and solve for X.
0 = -8x + 4
1. Move 4 to the left side so it's -4 = -8x
2. Divide by -8 to isolate X so it's -4/-8 = x
3. The negatives cancel out and become positive
4. Answer: X = 1/2
FOR Y
To find the y-intercept, substitute in 0 for X and solve for Y.
Y = -8(0) + 4
1. Since anything multipled by 0 is 0, it simply becomes Y = 4.
Answer: Y = 4
2(x + 2) = x - 4
2x + 4 = x - 4
2x - x = -4 - 4
x = -8
Solution: x = -8
Answer:its 0.58
Step-by-step explanation:
Answer:
a. 2x + 4
Step-by-step explanation:
Four more than twice a number
Let x = unknown number
Four more than twice of x
Twice of x can be written as 2x
Four more than 2x
Four more can be written as + 4
We get 2x + 4
