Solve this system of equations by using the substitution method. y=2x-5 6x+7=y
gogolik [260]

Answer:

x =  - 3 \: and \: y =  - 11

Step-by-step explanation:

L

since \: y = 2x - 5(equation \: 1) \:  \\

substitute \: for \: y \: in  \: equation \: 2 \:  (6x + 7 = y)

6x + 7 = y \\ 6x + 7 = 2x - 5 \\ collect \: like \: terms \\ 6x - 2x =  - 5 - 7 \\ 4x =  - 12 \\ x =  \frac{ - 12}{4}  \\ x =  - 3

substitute \: for \: x  in \: equation \: 1

y = 2x - 5 \\ y = 2( - 3) - 5 \\ y =  - 6 - 5 \\ y =  - 11

Can someone help please
Butoxors [25]

Answer: the slope of L is 1 and the slope of k is 2

Step-by-step explanation:

with rise over run, L's rise is 1 and run is 1 so it would be 1/1 which is equal to 1.  For k the rise would be 2 and run would be 1 so 2/1. I dont know if you learned it that way but there you go man.

Colt1911 [192]

Answer:

We need to right the proper algebraic expression to each case.

<h3>(a) Number <em>x </em>greater than <em>y</em></h3><h3><em />x>y<em /></h3><h3><em /></h3><h3>(b) The product of 2a and b is</h3><h3>2a \times b = 2ab</h3><h3 /><h3>(c) You want to by <em>x</em> chocolates for $2 and <em>y </em>chocolates for $3, how much would you pay for the purchase?</h3><h3>Total =2x+3y</h3><h3 /><h3>(d) Mr. Jan has <em>x </em>chickens and <em>y </em>cows, how many legs there are in total?</h3>

Each chicken has two legs, and each cow has four legs, so the expression of the total number of legs is

L=2x+4y

Where x\\ represents chickens and y represents cows.
