Answer:
D (X and Z)
Step-by-step explanation:
Answer:
8
Step-by-step explanation:
x^2 - 8 = 7x
x^2 - 7x - 8=0
(x - 8)(x + 1)=0
x - 8= 0 x + 1=0
x=8 x= -1
8 is the positive solution
Answer:
x-intercept: (6,0)
y-intercept: (0,4)
Step-by-step explanation:
The x-intercepts lay on the x-axis and therefore their y-coordinate is 0.
To find the x-intercept, you set y to 0 and solve for x.
2x+3y=12
Set y=0.
2x+3(0)=12
2x+0 =12
2x =12
Divide both sides by 2:
x =12/2
x =6
The x-intercept is (x,y)=(6,0).
The y-intercepts lay on the y-axis and therefore their x-coordinate is 0.
To find the y-intercept, you set x to 0 solve for y.
2x+3y=12
2(0)+3y=12
0+3y =12
3y =12
Divide both sides by 3:
y =12/3
y =4
The y-intercept is (0,4).
Answer:
(x+10)(x+10)
or (x+10)²
Step-by-step explanation:
this factories can use this
a² + 2ab + b²
; (a)² + 2(a)(10) + (b)²
= (a+b)²
