Answer:
Step-by-step explanation:
y=12x−2. parallel lines have the same slope 12
find b at point (3,-2)
y=12x+b
-2=12(3)+b
-2-36=b
b=-36
the equation has to be y=12x-38
when you input the point(3,-2)
-2=12(3)-38
-2=-2 correct
Answer:
1.
Statement: m∠A + m∠B + m∠C = <u>180°</u>
Reason: <u>Sum of Angles in a Triangle</u>
2.
Statement: 28° + x - 4° + <u>2x</u> = 180°
Reason: Substitution
3.
Statement: x = <u>52°</u>
Reason: Algebra
Answer:
Step-by-step explanation:
We know that
And we want to find
So, we will simply substitute <em>2w</em> for <em>z</em>. This yields:
Distribute. Therefore:
Since (x+1) is a factor of the given polynomial p(x), use what we call the "Factor Theorem." In this theorem, the polynomial p(x) is equal to zero so that no remainder will exist.
Let p(x) = 0, so
2x⁴ - 5x²<span> + cx + 1 = 0
We need to substitute a value for x. Then, use the factor x + 1 = 0 as x = -1.
2(-1)</span>⁴ - 5(-1)<span>²</span> + c(-1) + 1 = 0
Note that a negative one raise to the power of a positive number will result a positive one. Solving for c,
2(1) - 5(1) + c(-1) + 1 = 0
2 - 5 - c + 1 = 0
-c = -2 + 5 - 1
-c = 2
c = -2
