Answer:

500 miles

Step-by-step explanation:

2,500 divided by 5 = 500

Answer:

The missing value is 5.

Step-by-step explanation:

Since we already have x-value for the equation. What we need to do is to substitute the value of x in the equation.

Substitution

[tex]5x - 2y = 30[/tex]

Then we substitute x = 8 in the equation.

[tex]5(8) - 2y = 30 \\ 40 - 2y = 30 \\ 40 - 30 = 2y \\ 10 = 2y \\ \frac{10}{2} = y \\ 5 = y[/tex]

Answer Check

It is better to check the answer before jumping to the conclusion. We can check if the answer is right by substituting both terms in the equation. If the equation is true then the answer is correct. If the equation is false then one of the term is incorrect.

[tex]5x - 2y = 30[/tex]

Substitute x = 8 and y = 5 in the equation.

[tex]5(8) - 2(5) = 30 \\ 40 - 10 = 30 \\ 30 = 30[/tex]

The equation is true for (8,5)

Therefore, the missing value is 5.

Answer: 8

Step-by-step explanation:

By the angle bisector theorem,

[tex]\frac{12}{18}=\frac{x}{12}\\\\\frac{2}{3}=\frac{x}{12}\\ \\ x=\boxed{8}[/tex]

Answer:

19/15

Step-by-step explanation:

We need to find the difference, so subtraction. But first we should make them improper fractions:

(18/5)-(7/3)

Lets make the common denominator 15:

(54/15)-(35/15)

54-35= 19

Answer:

Option B

Step-by-step explanation:

Let's take a vertex G of quadrilateral GHJK to understand the rule for the translation,

From the graph attached,

Coordinates of G → (-5, 5)

Coordinates of the image point G' after the translation → G'(-5, 5)

Let the point G is translated 'a' units to the right and 'b' units down,

Rule for this translation,

G(x, y) → G'(x + a, y - a)

By this rule,

G(-5, 5) → G'(-5 + a, 5 - a)

-5 + a = -5 ⇒ a = 0

5 - a = 5 ⇒ a = 0

Therefore, vector that defines the translation will be,

<0, 0>

Option B is the the correct option.

The vector that describes the translation of the image is: b. (0, 0).

Recall the rules of translation:

Thus, from the image given to us showing the image of GHJK, using one of the vertex J' (-3, 3) and the translation rule, [tex](x + a, y - b)[/tex], the vector describing the translation can be determined as follows:

The coordinates of vertex J = (-3, 3)

[tex]x = -3 \\\\ y = 3[/tex]

[tex]J(-3, 3) = (-3 + a, 3 - b)\\\\-3 = -3 + a\\\\-3 + 3 = a\\\\\mathbf{0 = a} \\\\\\3 = 3 + b\\\\3 - 3 = b\\\\\mathbf{0 = b} \\\\[/tex]

Therefore, the vector that describes the translation of the image is: b. (0, 0).

d. Counterclockwise rotation about the origin by 90 degrees followed by reflection about the y-axis

Step-by-step explanation:

Solid transformation is a process which changes the orientation, shape and size of a given objects. Types of solid transformation are: rotation, reflection, dilation etc. This process would produce an image of the initial figure which has been transformed appropriately.

From the given question, figure PQRS can be transformed into P′Q′R′S′ by a  counterclockwise rotation at [tex]90^{o}[/tex] about the origin. This would be followed by a reflection about the y-axis.

Thus, the correct option is D.

The solution of the equation will be x = - 11/2 ± 5√5/ 2. Then the correct option is D.

The quadratic equation is given as ax² + bx + c = 0.

Then the solution is given as

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

The quadratic equation is given below.

x² + 11x + 121/4 = 125/4

  x² + 11x + – 1 = 0

Comparing with the standard equation, we have

a = 1, b = 11, and c = –1

Then the roots of the equation will be

[tex]\rm x = \dfrac{-11\pm \sqrt{11^2 - 4*1*(-1)}}{2*1}\\\\\\\rm x = \dfrac{-11 \pm \sqrt{121 +4}}{2}\\\\\\\rm x = \dfrac{-11\pm \sqrt{125}}{2}\\\\\\x = \dfrac{-11}{2}\pm \dfrac{5\sqrt{5}}{2}[/tex]

Then the correct option is D.

The ratio of the change in the y and x values, in the table gives the slope

graph of the linear function.

Correct response:

From the given table, we have;

The first difference of the y-values = 2 - 8 = -6 = Constant

The rate of change of the x-values = 1 = Constant

Therefore;

The function is a linear function;

The slope, m, is given by the formula;

[tex]Slope, \ m = \mathbf{ \dfrac{y_2 - y_1}{x_2 - x_1}}[/tex]

Taking a pair of points as follows;

(0, -4) = (x₁, y₁)

(2, -16) = (x₂, y₂)

We have;

[tex]m = \dfrac{-16 - (-4)}{2 - 0} = \dfrac{-16 + 4}{2} = \dfrac{-12}{2} = \mathbf{ -6}[/tex]

Answer:

p= -2

Step-by-step explanation:

24+8p= -40-24p

32p= -64

p= -2

Step-by-step explanation:

24 + 8p = -8(5+ 3p)       Original Problem

24 + 8p = -8(5) + -8(3p)   Distributive property

24 + 8p = -40 - 24p       Simplification

24 + 8p - 24 = -40 - 24p -24     Grouping the constants

8p = -64 - 24p                 Simplification

8p + 24p = -64 -24p +24p   Grouping the variables

all you have to do is subtract 7/8 from 3/8 and you get 4/8. And after that all that has to be done Is a bit of simplfing. Really this question is not that hard.

Answer: Ok first if you read the directions read them again, then you look at the problem carefully and make an equation that should look close to this: 0.75xp=c, Once you have that equation you have to replace the p with a 2 and multiply to get an answer of 1.50.
