Y = 7x + 7<br> y = -7x + 19<br><br> Solve the system algebraically.
shtirl [24]
Hello,

To this question, It's only directly sum the equations:

y + y = 7x - 7x +7+19

2y = 0x + 26

2y = 26

y = 26 ÷ 2

y = 13


Now only to replace y = 13 in the equation of up or of down.

Then stay:

y = 7x + 7

13 = 7x + 7

7x = 13 -7

7x = 6

x = 6 / 7

Each lap Jeffrey needs to run is one tenth of a mile he wants to run threee fifths of a mile how many laps does he need to run
kipiarov [429]

Answer:

6 laps

Step-by-step explanation:

Each lap Jeffrey needs to run is one tenth of a mile he wants to run threee fifths of a mile how many laps does he need to run

One tenth of a mile = 1/0

Three fifths of a mile = 3/5

From the question:

1/10 mile = 1 lap

3/5 mile = x

Cross Multiply

1/10 mile × x = 3/5 mile × 1 lap

x = 3/5 mile × 1 lap/ 1/10 mile

x = 3/5 ÷ 1/10

x = 3/5 × 10/1

x = 6 laps

Therefore, for there fifths of a mile(3/5) he needs to run 6 laps

Can someone pls help
Dominik [7]

Point-slope form:   y - y₁ = m(x - x₁)

m is the slope, (x₁ , y₁) is your point

So your point-slope equation is:

m = -4          (x₁ , y₁) = (4 , -9)

y - y₁ = m(x - x₁)

y + 9 = -4(x - 4)
