Y=6x-11<br> -2x-3y=-7 gnjjj
KiRa [710]

Answer:

x=2 y=1

Step-by-step explanation:

Solve the equations by substituting y=6x-11 into -2x-3y=-7.

-2x-3(6x-11)=-7

-2x-18x+33=-7

-20x+33=-7

-20x=-7-33

-20x=-40

x=2

To find y, substitute this value into the equation and solve for y.

y=6(2)-11

y=12-11

y=1

Anybody please help me with question 3-5, thank you so much!!! You are a life saver :))))
Marta_Voda [28]

Answer:

3) 109.27

4) 58.80

5) 48.65

Step-by-step explanation:

First divide the cost by the number of units to get the individual cost of each item.

Then multiply by the new number of units.

For example:  78.05 ÷ 5 = 15.61 for each.

                       15.61 x 7 = 109.27

Find two consecutive positive integers such that the sum of their squares is 421 .
maria [59]
We assume the two numbers are x and (x+1)
so x^2+(x+1)^2=421
x^2+(x^2+2x+1)=421
2x^2+2x-420=0
According to the formula of quadratic 
x=14 or-15
cuz we know the two numbers are integers
so x=14
therefore the other number is 15
To make sure that's correct
14^2+15^2=421

Hope that helps you!!
