Kenna's is earning money. The following equation models her earnings: y=55x+1300

labwork [276]

Answer:

In 14 weeks, they will have the same earnings.

Step-by-step explanation:

y = 55x + 1300 -------- (1)

y = 25x + 1720 -------- (2)

(2) = (1)

55x + 1300 = 25x +1720

55x - 25x = 1720 - 1300

30x = 420

30x ÷ 30 = 420 ÷ 30

x = 14

In the diagram, lines AB , CD, and EF intersect at G

Ghella [55]

Answer:

D. 70°

Step-by-step explanation:

Given:

m<DGB = 35°

m<CGF = 75°

Required:

m<AGE

SOLUTION:

m<EGD = m<CGF (vertical angles are congruent)

m<EGD = 75°

m<AGE + m<EGD + m<DGB = 180° (angles on a straight line)

m<AGE + 75° + 35° = 180° (substitution)

m<AGE + 110° = 180°

Subtract 110 from each side of the equation

m<AGE = 180° - 110°

m<AGE = 70°

Find the equation of the line passing<br> through the points (2, 1) and (5, 10).<br> y = [? ]x + [ ]

sladkih [1.3K]

Answer:

$y=3x-5$

Step-by-step explanation:

$m=10-1/5-2$

$m=9/3$

$m=3$

$y=3x+b$

$x=2, y=1$

$1=3(2)+b$

$1=6+b$

$-5=b$

$y=3x-5$

Which explains whether or not the function represents a direct variation?

s2008m [1.1K]

Answer:

The function represents a direct variation

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent a direct variation if it can be expressed in the form $y/x=k$ or $y=kx$

In a linear direct variation the line passes through the origin and the constant of proportionality k is equal to the slope m

Let

$A(0,0)$ ------> the line passes through the origin

$B(2,10)$

Find the value of k------> substitute the value of x and y

$y/x=k$ -----> $k=10/2=5$

$C(4,20)$

Find the value of k------> substitute the value of x and y

$y/x=k$ -----> $k=20/4=5$

$D(6,30)$

Find the value of k------> substitute the value of x and y

$y/x=k$ -----> $k=30/6=5$

$E(8,40)$

Find the value of k------> substitute the value of x and y

$y/x=k$ -----> $k=40/8=5$

The value of k is equal in all the points of the table and the line passes through the origin

therefore

The function represents a direct variation

the equation of the direct variation is equal to

$f(x)=5x$
