Answer:
y = x^2 +2x -8
Step-by-step explanation:
For x-intercepts p and q, factors of the parabola's equation are (x-p) and (x-q). Since the leading coefficient is 1, those are the only factors.
y = (x -2)(x -(-4))
y = (x -2)(x +4) = x(x +4) -2(x +4) . . . . use the distributive property
y = x^2 +4x -2x -8 . . . . use the distributive property again
y = x^2 +2x -8 . . . . . . . .equation in standard form
[tex]x^{2} + 36x + 324 = (x + m)^{2} [/tex]
which of the following is the value of m?
A. 36
B. 18
C. 12
D. 6
Answer:
B. 18
Step-by-step explanation:
[tex]x^{2} + 36x + 324 = (x + m)^{2} [/tex]
[tex](x+18)^{2}= (x + m)^{2} [/tex]
[tex]\cancel x+18= \cancel x + m[/tex]
[tex]18= m[/tex]

Write in Slope Intercept form
Answer:
y=5/2x
Step-by-step explanation:
the y intercept is (0,0) so it isn't included in the equation. now we know the middle solution isn't correct. the points we use to find slope are (-2,-5) and (2,5) which ends up being 5/2.

Answer:
GCHE
Step-by-step explanation:
Answer and Explanation:
Problem 1:
4x - 12 = 16
4x = 28
x = 28 / 4
x = 7, G
Problem 2:
5x + 10 = - 25
5x = - 35
x = - 35 / 5
x = -7, C
Problem 3:
x / 2 + 11 = 12
x / 2 = 12 - 11 = 1
x = 2 * 1
x = 2, H
Problem 4:
7.5 * x + 10 = -5
x = -2, E

Answer:
21
Step-by-step explanation:
It is given that two lines are parallel, and hence the corresponding angles are congruent, by corresponding angles postulate. It is also given that the triangles in the photo share an angle, by the reflexive property, the shared angle is congruent. Hence one can use angle-angle to determine that the two triangles in the picture are similar.
Using this, one can set up a proportion with the sides. The ratios of any two corresponding sides are the same as any other two corresponding sides in the triangle, respectively, this is due to the corresponding parts of similar triangles theorem.

To compute the perimeter of a rectangle, you add the length, l , and width, w , and double this sum.
This means you can find the perimeter of a rectangle by evaluating the expression 2 (1 + w ).
Use this expression to find the perimeter of a rectangle with length 30 and width 75.
210 (A)
135 (B)
180 (C)
107 (D)
Answer:
210 (A)Step-by-step explanation:
Use the formula:
P = 2(l + w)Substitute the values and find P:
P = 2(30 +75) = 2(105) = 210Correct choice is A
Answer:
given length [l]=30
width[w]=75
perimeter= 2 (l + w )=2(30+75)=210
so
answer is A.210

what is g in this problem 4-(9g-5)=-18
Step-by-step explanation:
Let's solve your equation step-by-step.
4−(9g−5)=−18
Step 1: Simplify both sides of the equation.
4−(9g−5)=−18
4+−1(9g−5)=−18(Distribute the Negative Sign)
4+−1(9g)+(−1)(−5)=−18
4+−9g+5=−18
(−9g)+(4+5)=−18(Combine Like Terms)
−9g+9=−18
−9g+9=−18
Step 2: Subtract 9 from both sides.
−9g+9−9=−18−9
−9g=−27
Step 3: Divide both sides by -9.
−9g−9=−27−9
g=3
