What is the vertex of the parabola with the equation y=1/5x^2 + 2x - 8
Answer:
(-5,-13)
Step-by-step explanation:
Find the vertex of the parabola y=1/5x^2+2x−8.
In this equation a=15 and b = 2.
x= -2/2(1/5) = -2/2/5 = -2/1 * 5/2 = -5
Substitute −5 into the equation y=1/5x^2+2x−8
y=1/5(−5)^2+2(−5)−8
y=5−10−8
y=−13
The vertex is (−5 , −13)
ΔABC is dilated from the origin at a scale factor of 3 to create ΔA′B′C′.
Select the option that completes the statement:
The triangles' corresponding angles are ________, and their corresponding sides are ________; therefore, the triangles are ________.
A. congruent; similar; proportional
B. congruent; proportional; similar
C. proportional; congruent; similar
D. proportional; similar; congruent
The statement is that when ΔABC is dilated from the origin at a scale factor of 3 to create ΔA′B′C′, their corresponding angles are congruent, and their corresponding sides are proportional; therefore, the triangles are similar. The correct answer is option B
In order to prove the given statement, we will need to know that dilation is a transformation in which a figure is stretched in a particular direction by a certain factor (scale factor) while keeping its shape constant. We use this transformation to create similar figures.
When a figure is dilated, all of its corresponding sides are stretched, and the angles remain the same.The corresponding angles are the angles that have the same location in the two similar figures. The corresponding sides are the sides that have the same position in the two similar figures.
Since the triangles are similar, we can say that the corresponding sides of the triangles are proportional. On the other hand, the corresponding angles are congruent.
The correct option is B, which states that the triangles' corresponding angles are congruent, their corresponding sides are proportional, and therefore the triangles are similar.

Find the value of r so that the line through (1,2) and (-5,r) has a slope of 1/2
Answer:
The value of r is -1
Step-by-step explanation:
The slope of a Line
Suppose a line passes through points A(x1,y1) and B(x2,y2). The slope can be calculated with the equation:
[tex]\displaystyle m=\frac{y_2-y_1}{x_2-x_1}[/tex]
The points are (1,2) and (-5,r), and the slope is 1/2, thus
[tex]\displaystyle \frac{r-2}{-5-1}=\frac{1}{2}[/tex]
Operating:
[tex]\displaystyle \frac{r-2}{-6}=\frac{1}{2}[/tex]
Multiplying by -6:
[tex]2(r-2)=-6[/tex]
Dividing by 2:
[tex]r-2=-3[/tex]
Add 2:
[tex]r=-3+2=-1[/tex]
[tex]\boxed{r=-1}[/tex]
The value of r is -1

In AHIJ, m_H=(8x-6)°, m_1=(2x-4)', and m2)=(x-8)". Find mcH.
9514 1404 393
Answer:
m∠H = 138°
Step-by-step explanation:
Perhaps you have ΔHIJ and want the measure of ∠H.
∠H +∠I +∠J = 180°
(8x-6) +(2x-4) +(x-8) = 180
11x -18 = 180 . . . . . . collect terms
11x = 198 . . . . . . . . . add 18
x = 18 . . . . . . . . . . . divide by 11
Then angle H is ...
m∠H = (8(18) -6)°
m∠H = 138°

In #13, perform the indicated multiplication (using Distributive Property):

3) Find the perimeter of the following
polygon.
-4 yd.
9 yd.
P =
Answer:
p = 42yds.
Step-by-step explanation:
The single dashes indicate that each of those lines are equivalent
The double dashed lines are equal to each other
Because there are 6 single dashed lines that are all equal to 4 yards, and 2 double dashed lines that are both equal to 9 yards, your equation will look like this:
(4 x 6)+(9 x 2)=p
now just solve this using the order of operations
4 x 6 = 24 and 9 x 2 = 18 and 18 + 24 = 42 so p = 42yds.
The polygons are similar. Find the value of x and y.
Answer:
x = 9, y = 27
Step-by-step explanation:
Since the figures are similar then the ratios of corresponding sides are equal, that is
[tex]\frac{x-1}{6}[/tex] = [tex]\frac{16}{12}[/tex] ( cross- multiply )
12(x - 1) = 96 ( divide both sides by 12 )
x - 1 = 8 ( add 1 to both sides )
x = 9
Also
[tex]\frac{y+1}{21}[/tex] = [tex]\frac{16}{12}[/tex] ( cross- multiply )
12(y + 1) = 336 ( divide both sides by 12 )
y + 1 = 28 ( subtract 1 from both sides )
y = 27

Which function has the same graph as x + y = 112 OA x) = -y + 11 OB. f(x) = -x + 11 Oc. x) = x- 11 O D. x) = y-11
Answer:
B. f(x) = -x + 11
Step-by-step explanation:
First if you rearrange the equation you get f(x) = -x + 11, like this:
x + y = 11
Minus x from both sides
y = -x + 11
F(x) and y are interchangeable so we just put f(x) in
f(x) = -x + 11
Each of the graphs are attached and we see that they are the same!

Jackie took $24 to the movie theater with her and her friends. The price of each bag of popcorn is $4 and the price of each candy bar is $3.
Let the x axis represent the number of candy bars and the y axis represent the number of bags of popcorn.
What is the x intercept and what does it mean?
What is the y intercept and what does it mean?
Answer:
x-intercept is 8, meaning if you get 8 candy bars, you can get 0 popcorn bags.
y-intercept is 6, meaning if you get 6 popcorn bags, you can get 0 candy bars.
Step-by-step explanation:
Answer:
When Jackie had 0 candy bars, she had 6 (y-intercept) bags of popcorn and when Jackie had 0 bags of popcorn, she had 8 (x-intercept) bars of candy.
Step-by-step explanation:
The y-axis represents the amount of popcorn bags she has and the x-axis has the amount of candy bars. When the linear line intercepts with either axis, at least one axis is always at zero.
