3.Which linear equations also represents a direct variation? (select all that apply)
y = 2/3x
y = -2x – 4
y = 5x
y = 3x + 2

Answer:

x=5

Step-by-step explanation:

XY=5x and 25. Therefore, 5x and 25 have the same value. 5 times 5 is 25 so x=5

Answer: 6x=25

Answer:

the person above me is correct

Step-by-step explanation:

Answer:

s = 5.1

Step-by-step explanation:

[tex]0.7 (3s + 4)-1.1s = 7.9\\[/tex]

Multiply both sides of the equation by 10

[tex]0.7\left(3s+4\right)\cdot \:10-1.1s\cdot \:10=7.9\cdot \:10\\\\= 7\left(3s+4\right)-11s=79\\[/tex]

Expand

[tex]\mathrm{Expand\:}7\left(3s+4\right)-11s:\\\quad 10s+28[/tex]

Subtract 28 from both sides

[tex]10s+28-28=79-28[/tex]

Simplify

[tex]10s=51[/tex]

Divide both sides of the equation by 10

[tex]\frac{10s}{10}=\frac{51}{10}[/tex]

Simplify

[tex]s=\frac{51}{10}\\\\Decimal = 5.1[/tex]

Answer:

-10/-2

Step-by-step explanation:

Answer:

-10/-2

Step-by-step explanation:

Answer:

q = 5/6

Step-by-step explanation:

First, we distribute.

16q - 10 = 4q

Then, we combine like terms.

-10 = 4q - 16q

-10 = -12q

Finally, we divide -12 on both sides.

5/6 = q, or q = 5/6

Answer:

16.1

Step-by-step explanation:

37.03/2.3 = 16.1

Answer:

[tex]\boxed{\bold{\huge{\boxed{16.1}}}}[/tex]

Step-by-step explanation:

Let the first number be x and the second number be y

So, the condition is:

[tex]x * y = 37.03[/tex]

Given that x = 2.3

[tex]2.3 * y = 37.03[/tex]

Dividing both sides by 2.3

[tex]y = \frac{37.03}{2.3}[/tex]

[tex]y = 16.1[/tex]

Answer:

Number of hours= 7.5

Step-by-step explanation:

Giving the following information:

The company charges a cleaning fee of $100 and an hourly rate of $45.

Her total cost for the night was $437.50

First, we need to structure the total cost formula:

Total cost= 100 + 45*x

x= number of hours

437.5= 100 + 45x

337.5/45= x

x= 7.5

Number of hours= 7.5

Answer:

Kaya rented the limo for about 7.5 hours

Answer:

Step-by-step explanation:

The length of a line segment or the distance between two points can be found by using the formula

[tex]d = \sqrt{ ({x1 - x2})^{2} + ({y1 - y2})^{2} } \\ [/tex]

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

J(-4,2) and G(146,52)

The the length of the line segment joining the points is

[tex] |JG| = \sqrt{ ({ - 4 - 146})^{2} + ({2 - 52})^{2} } \\ = \sqrt{ ({ -150})^{2} + ({ -50})^{2} } \\ = \sqrt{22500 + 2500} \\ = \sqrt{25000} \\ = 50 \sqrt{10} \\ = 158.11388[/tex]

We have the final answer as

Hope this helps you

Answer:

c=(1,-8)

d=(7,-8)

e=(7,0)

f=(1,0)

Step-by-step explanation:

It super simple, just just move each point to the right 5 lines/units, and up 2 lines/units.

The coordinates of the vertices after a translation 5 units right and 2 units up. C =(1,-8), D =(7,-8), E =(7,0) and F =(1,0)

Suppose the graph is drawn on the coordinate plane.

Let the shifting be (x,y) → (x+a, y+b)

Then, add 'a' to all x coordinates of the graph's points. Add 'b' to all y coordinates of the graph's points.

The resultant set of new points will be plotted.

Thus it is called origin shift since we think of it as the origin was picked and placed at the point (a,b)(in this case) along with those two axes (x and y axes) and now everything will be measured from this new axes' frame.

Therefore, the coordinates of the vertices after a translation 5 units right and 2 units up.

C =(1,-8)

D =(7,-8)

E =(7,0)

F =(1,0)

Answer:

640 students

Step-by-step explanation:

We are told in the question that 4 out of every 5 students owns a bicycle

This also means , out of every 5 students only 1 does not have bicycle

Then we have a ratio of 4 : 1

This means a fraction of 4/5 students own a bicycle in a school

Based on this result, how many of the 800 students in a school own a bicycle?

This calculated as:

4/5 × 800

= 640 students

Therefore, 640 students out of 800 students own a bicycle

Answer:

No, a pentagon can NOT be a cross-section of a triangular prism.

Step-by-step explanation:

Prisms have a uniform cross-section and are named after their cross-section. Hence, the cross section of a triangular prism is a triangle. The only prism with a pentagon cross-section is a pentagonal prism.

Answer:

the measurement of C is 83° because AB = BE so B = A

180° (triangle ABE) - 57°(2) = 66°

180° (line AD) - 66° = 114°

180° (line BC) - 114° = 66° (angle E)

180° (Triangle DCE) - 66° - 31° = 83°

Answer:

C)N.

Because variables represent an unknown number.

Answer:

C

Step-by-step explanation:

let y = f(x) and rearrange making x the subject, that is

y = [tex]x^{4}[/tex] + 7 ( subtract 7 from both sides )

y - 7 = [tex]x^{4}[/tex] ( take the fourth root of both sides )

[tex]\sqrt[4]{y-7}[/tex] = x

Change y back into terms of x where x is g(x)

g(x) = [tex]\sqrt[4]{x-7}[/tex] , x ≥ 7
