Answer:
y + 1 = 2(x+1)
Step-by-step explanation:
hope this helps
Answer:
2 hours
Step-by-step explanation:
I substituted y for 126 and solved like so:
126 = 38x + 50
126 - 38x = 50
(126-126) - 38x = 50 - 126
-38x = -76
-38x/-38 = -76/-38
X = 2
There ya go! Hope this helps, good luck :)
2x squared would be you final answer
Answer:
x^2 +3x +2=0 then x = -1 or x= -2 so their is 2 solutions
Answer: the equation is
4x^2 + 4x - 12
Step-by-step explanation:
A quadratic equation is an equation in which the highest power of the unknown is 2.
The general form of a quadratic equation is expressed as
ax^2 + bx + c
Where
a is the leading coefficient
c is a constant
Assuming we want to write the quadratic equation in x, from the information given, the roots which are given are -2 and 1 and the leading coefficient is 4.
Therefore, the linear factors of the quadratic equation will be (x+2) and (x-1)
the equation becomes
(x+2)(x-1)
= x^2 - x +2x - 3
= x^2 + x - 3
Given a leading coefficient of 4, we will multiply the quadratic expression by 4. It becomes
4(x^2 + x - 3)
= 4x^2 + 4x - 12
