Answer:

-4x=4+4

x=8/-4

x= -2

not sure how I'm supposed to verify

Answer: x = -10

Step-by-step explanation:

7 (x + 5) = -35

Distribute 7 to x + 5

7 * x = 7x

7 × 5= 35

7x + 35 = -35

Subtract both sides by 35

7x = - 70

Divide both sides by 7

x = -10

Answer: 262.6

Step-by-step explanation: Well if she sold 110 hamburgers on tuesday for $545 That is a simple division equation (545/110). After dividing the answer would be how much each hamburguer cost on its own ( 4.954545454545455), you would then multiply that by the number of hamburgers she sold (53) and get your answer. (262.5909090909091) I am not quite sure where she wants us to round the answer to. so I just did the tens place.

Step-by-step explanation:

Divide 45 / 5 to get 9

As 5 * 9 = 45

Answer:

[tex](-21)^\frac{6}{5}[/tex]

Step-by-step explanation:

Which expression represents [⁵√(−21)]⁶ in rational exponent form?

Solution:

Rational numbers are numbers which can be expressed as fractions in the form a / b, where a, b are integers and b is not equal to zero.

A rational exponent is an exponent that is a fraction. For example √2 = [tex]2^\frac{1}{2}[/tex].

When expressing a number in rational exponent form, the numerator of the fractional exponent refers to a normal power, but the denominator refers to the root.

[tex][\sqrt[5]{(-21)}]^6 = (-21)^\frac{6}{5}[/tex]

Answer:

60.

Step-by-step explanation:

I can't see the question above this and what information it gives, but If I'm not mistaken, that shape is a rectangle, so regardless of whether there's a piece of the last side missing, the sides across from each other are congruent in size.

So if the top is 14, then the bottom is 14, and since the left side is 16, then the side missing a piece adds up to 16.

(14*2) + (16*2) =

28 + 32 = 60.

Answer:

New force = 24 N

Step-by-step explanation:

The force acting on the object varies directly with the object's acceleration

i.e.

[tex]\dfrac{F_1}{F_2}=\dfrac{a_1}{a_2}[/tex] ...(1)

We have,

F₁ = 40 N, a₁ = 10 m/s², a₂ = 6 m/s₂, F₂ =?

Put all the values in equation (1).

[tex]F_2=\dfrac{F_1a_2}{a_1}\\\\F_2=\dfrac{40\times 6}{10}\\\\F_2=24\ N[/tex]

So, the new force becomes 24 N.

Answer:

Answer: -4

Step-by-step explanation:

13 - 9 = 4

9 - 5 = 4

so, we can see that it is decreasing by 4 each time.

Answer:

common difference is -4

Step-by-step explanation:

The common difference is the amount we add  between terms

13 + d = 9

Subtract 13 from each side

13+d-13 = 9-13

d = -4

Check

9+d = 5

9 + -4 = 5

5= 5

This is true so the common difference is -4

Answer:

The required equation is:

[tex]y = -\frac{3}{2}x+9[/tex]

Step-by-step explanation:

To find the equation of a line, the slope and y-intercept is required.

The slope can be found by finding the slope of given line segment. A the perpendicular bisector of a line is perpendicular to the given line, the product of their slopes will be -1 and it will pass through the mid-point of given line segment.

Given points are:

[tex](x_1,y_1) = (8,10)\\(x_2,y_2) = (-4,2)[/tex]

We will find the slope of given line segment first

[tex]m = \frac{y_2-y_1}{x_2-x_1}\\= \frac{2-10}{-4-8}\\=\frac{-8}{-12}\\=\frac{2}{3}[/tex]

Let m_1 be the slope of perpendicular bisector then,

[tex]m.m_1 = -1\\\frac{2}{3}.m_1 = -1\\m_1 = \frac{-3}{2}[/tex]

Now the mid-point

[tex](x,y) = (\frac{x_1+x_2}{2} , \frac{y_1+y_2}{2})\\= (\frac{8-4}{2} , \frac{10+2}{2})\\=(\frac{4}{2}, \frac{12}{2})\\=(2,6)[/tex]

We have to find equation of a line with slope -3/2 passing through (2,6)

The equation of line in slope-intercept form is given by:

[tex]y = m_1x+b[/tex]

Putting the value of slope

[tex]y= -\frac{3}{2}x+b[/tex]

Putting the point (2,6) to find the y-intercept

[tex]6 = -\frac{3}{2}(2)+b\\6 = -3+b\\b = 6+3 =9[/tex]

The equation is:

[tex]y = -\frac{3}{2}x+9[/tex]

The equation of the perpendicular bisection that passes through the point (2,6) and has a slope -3/2 is [tex]\rm (y-6)=-\dfrac{3}{2}(x-2)[/tex] and this can be determined by using the point-slope form of the line.

Given :

Endpoints  -- (8,10) and (-4,2)

The following steps can be used in order to determine the equation of the perpendicular bisector:

Step 1 - First, determine the slope of the line that passes through points (8,10) and (-4,2).

[tex]\rm m =\dfrac{2-10}{-4-8}[/tex]

[tex]\rm m = \dfrac{8}{12}[/tex]

[tex]\rm m = \dfrac{2}{3}[/tex]

Step 2 - So, the slope of the perpendicular bisector is given by:

[tex]\rm m'm = -1[/tex]

[tex]\rm m' = -\dfrac{3}{2}[/tex]

Step 3 - Now, determine the midpoint of the line that passes through the points (8,10) and (-4,2).

[tex]\rm x = \dfrac{8-4}{2}=2[/tex]

[tex]\rm y = \dfrac{10+2}{2}=6[/tex]

Step 4 - So, the equation of the perpendicular bisection that passes through the point (2,6) and has a slope -3/2 is:

[tex]\rm (y-6)=-\dfrac{3}{2}(x-2)[/tex]

Answer:

-32p +56

Step-by-step explanation:

distribute the 8 to everything in the parenthesis

Answer:

15 is the multiply of the number

Answer:

The coordinates of the other point are:

(x₂, y₂) = (18, 20)

Hence, option A is correct.

Step-by-step explanation:

Given

To determine

Using the Mid-point formula between (x₁, y₁) and (x₂, y₂)

[tex]\left(x,\:y\right)=\:\left(\frac{x_2+x_1}{2},\:\:\frac{y_2+y_1}{2}\right)[/tex]

Here:

(x, y) is the midpoint between (x₁, y₁) and (x₂, y₂)

substituting (x, y) = (0, 5) and (x₁, y₁) = (-18, -10) in the formula

[tex]\left(0,\:5\right)=\:\left(\frac{x_2+\left(-18\right)}{2},\:\:\frac{y_2+\left(-10\right)}{2}\right)[/tex]

equating

[tex]0=\frac{x_2+\left(-18\right)}{2}[/tex]

[tex]x_2-18=0[/tex]

Add 18 to both sides

[tex]x_2-18+18=0+18[/tex]

[tex]x_2=18[/tex]

also

[tex]5=\frac{y_2+\left(-10\right)}{2}[/tex]

[tex]10=y_2+\left(-10\right)[/tex]

[tex]10=y_2-10[/tex]

[tex]10+10=y_2[/tex]

[tex]10+10=y_2[/tex]

[tex]y_2=20[/tex]

Therefore, the coordinates of the other point are:

(x₂, y₂) = (18, 20)

Hence, option A is correct.

Answer:

(x₂, y₂) = (18, 20)

Given:

[tex]f(x)=4x-7[/tex]

[tex]g(x)=4x[/tex]

To find:

The expression for f(f(x)).

Solution:

We need to find f(f(x)).

[tex]f(f(x))=f(4x-7)[/tex]                             [tex][\because f(x)=4x-7][/tex]

[tex]f(f(x))=4(4x-7)-7[/tex]                             [tex][\because f(x)=4x-7][/tex]

Using distributive property, we get

[tex]f(f(x))=4(4x)+4(-7)-7[/tex]

[tex]f(f(x))=16x-28-7[/tex]

[tex]f(f(x))=16x-35[/tex]
