Which ordered pair (x, y) satisfies the system of equations shown below?
9x - y = 63
x = y +7

Answers

Answer 1

Answer: (7, 0)

Step-by-step explanation:

We have the system of equations:

9*x - y = 63

x = y + 7

We can see that the "x" is isolated in the second equation, then we can replace it in the first equation to get:

9*x - y = 63

9*(y + 7) - y = 63

Now we have an equation that only depends on one variable, so we can solve it:

9*y + 63 - y = 63

8*y + 63 = 63

8*y = 63 - 63 = 0

y = 0/8 = 0.

Now we know the value of y, we can replace this in one of the initial equations to find the value of x, i will replace this in the second equation:

x = y + 7 = 0 + 7 = 7

Then the point that is a solution for the system of equations is (7, 0)

3) Find the perimeter of the following
polygon.
-4 yd.
9 yd.
P =

Answers

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.

Quadratic Equation Solving

The standard representation of a quadratic equation is:

[tex]ax^2+bx+c=0[/tex]

where a,b, and c are constants.

Solving with the quadratic formula:

[tex]\displaystyle x=\frac{-b\pm \sqrt{b^2-4ac}}{2a}[/tex]

We have the following equation to solve:

[tex]x+x^2-5x-5=0[/tex]

Before attempting to solve it, we must simplify the equation.

Collecting like terms and reordering:

[tex]x^2-4x-5=0[/tex]

Here: a=1, b=-4, c=-5

The discriminant of this quadratic equation is:

[tex]d=b^2-4ac[/tex]

[tex]d=(-4)^2-4(1)(-5)=16+20=36[/tex]

Given d is positive, the equation has two roots, and since d is a perfect square, both roots are rational.

Applying the formula:

[tex]\displaystyle x=\frac{4\pm \sqrt{36}}{2(1)}[/tex]

[tex]\displaystyle x=\frac{4\pm 6}{2}[/tex]

Dividing by 2:

[tex]x=2\pm 3[/tex]

Separating both roots:

x = 2 + 3 = 5

x = 2 - 3 = -1

The zeros of the polynomial are -1 and 5

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?

Answers

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.

The polygons are similar. Find the value of x and y.

Answers

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

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°

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

Answers

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.
