The value of x is 5/6 and y is 8/5.

Step-by-step explanation:

Given,

12x+15y=34   Eqn 1

-6x+5y=3   Eqn 2

Multiplying Eqn 2 by 2

2(-6x+5y=3)\\-12x+10y=6\ \ \ Eqn 3

Adding Eqn 1 and 3

(12x+15y)+(-12x+10y)=34+6\\12x+15y-12x+10y=40\\25y=40

Dividing both sides by 25

\frac{25y}{25}=\frac{40}{25}\\y=\frac{8}{5}

Putting y= 8/5 in Eqn 1

12x+15(\frac{8}{5})=34\\12x+3*8=34\\12x+24=34\\12x=34-24\\12x=10

Dividing both sides by 12

\frac{12x}{12}=\frac{10}{12}\\x=\frac{5}{6}

The value of x is 5/6 and y is 8/5.

Y=6<br> X+2y=16<br><br> Can someone one help me out its a substitution and system of equations graph
Nikitich [7]
If you know that y = 6. You just have to switch Y by 6.

x + 2y = 16
x + 2*6 = 16
x + 12 = 16
x = 16 - 12
x= 4

4 + 2*6 = 16

Hope this helps !

Suppose the linear regression line y=2.1x+130 predicts sales based on the money spent on advertising. If x represents the dollar
slega [8]

Linear regression line y=2.1x+130 predicts sales based on the money spent on advertising.

Linear regression represents the relationship between two variables. the value of y depends on the value of x.

x represents the dollars spent in advertising and y represents the company sales in dollars.

We need to find out sales y when $150 spends on advertising.

Plug in 150 for x and find out y

y = 2.1 x + 130

y = 2.1 (150) + 130

y= 445

The company expects $445 in sales
