Answer:
x = - 4, x = 10, x = 7
Step-by-step explanation:
To find the zeros let y = 0, that is
(x + 4)(x - 10)(x - 7) = 0
Equate each factor to zero and solve for x
x + 4 = 0 ⇒ x = - 4
x - 10 = 0 ⇒ x = 10
x - 7 = 0 ⇒ x = 7
Answer:
5^14
Step-by-step explanation:
We use the laws of indices:
When there is a power outside the bracket multiply the powers.
(a^m)^n=a^m×n
So (5^7)^2=
5^7×2
5^14
Answer:
220
Step-by-step explanation:
Sper ca team ajutat okkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkk
The slope-intercept form:
m - slope
b - y-intercept
The formula of a slope:
substitute the coordinates of the points (8, 0) and (20, 12) to the formula:
y = 1x + b = x + b
Put the coordinates of the point (8, 0) to the equation of a line:
0 = 8 + b <em>subtract 8 from both sides</em>
-8 = b
<h3>Answer: y = x - 8</h3>
