5 0

Answer:

x = 10

y = -15

Step-by-step explanation:

putting value of y in equation 2

2x+(-x-5)=5

2x-x-5=5

x-5=5

x=5+5

x= 10

putting value of x in equation 1

y=-10-5

y= - 15

What is the equation, in slope-intercept form, of the line parallel to y = 5x +2 that passes through the point with coordinates

DaniilM [7]

Answer:

Slope - intercept form y = 5x+17

The equation of the parallel line to the given line is 5x-y +17=0

Step-by-step explanation:

Explanation

The equation of the straight line is y= 5x+2

5x - y +2=0

The equation of the straight line is 5x-y+2=0

Given that the point(-3,2)

The equation of the parallel line to the given line is

5x -y +k=0

5(-3) - 2+k=0

-15 -2 +k =0

-17 +k=0

k =17

The equation of the parallel line to the given line is 5x-y +17=0

Final answer:-

Slope - intercept form y = mx+c

Slope - intercept form y = 5x+17

Lee and Maya are collecting leaves for an art project. Lee collect 24/100 of the tiral number of leaves needed. Maya collects 4/

Burka [1]

Answer:

The fraction of the total number of leaves did they collect altogether is $\frac{16}{25}$

Step-by-step explanation:

This question can be solved by a sum of fractions.

Lee collect 24/100 of the tiral number of leaves needed.

Maya collects 4/10 of the total number of leaves needed.

What fraction of the total number of leaves did they collect altogether?

This is the sum of 24/100 and 4/10.

The lesser common multiple between 100 and 10 is 100. So

$\frac{24}{100} + \frac{4}{10} = \frac{24 + 10*4}{1001} = \frac{64}{100}$

We can simplify by four

The fraction of the total number of leaves did they collect altogether is $\frac{16}{25}$
