Step-by-step explanation:
Answer: x= 1.4 or x=7/5
Step-by-step explanation:
2(5x)=14
Divide both sides by 2
5x=7
divide again this time both sides by 5 to solve for x
x=7/5 or 1.4 as a decimal
Answer:
1/2.
Step-by-step explanation:
the slope of a line perpendicular to another is the reciprocal of the original lines slope.
Answer:
(5, - 4)
Step-by-step explanation:
Given a quadratic in standard form : ax² + bx + c : a ≠ 0
Then the x- coordinate of the vertex is
= -
x² - 10x + 21 ← is in standard form
with a = 1, b = - 10, so
= - = 5
Substitute x = 5 into the quadratic for the corresponding value of y
y = 5² - 10(5) + 21 = 25 - 50 + 21 = - 4
vertex = (5, - 4)
