Answer: this is the answer please follow to the explanation
Step-by-step explanation:
21x + 14y = 168. X=2y
14y = -21x +168. 2y=x
14 divided by 14 on one side and
-21 + 168 divided by 14 on the other side
You should get...
Y= -3/2x +12
For part 2 where they want you to put the 2 numbers in, you should put the point they intercept which is (6,3).
Well, have a good day
Answer: he saved $15
Step-by-step explanation:
The regular price is $5.00 per rose bush, but last week they were on sale at 2 for $8.50. This means that the amount that one would cost is
8.5/2 = $4.25
If Jim bought 20 rose bushes last week, it means that the amount that he paid for 20 rose bushes is
20 × 4.25 = $85
The regular price is $5.00 per rose bush. If he had bought at the regular price, the amount that he would have paid is
5 × 20 = $100
Therefore, the amount saved by the bushes on sale is
100 - 85 = $15
X - 4 = y^2
Since you want y to the first power you have to take the square root of y^2.
If you take the square root of the right side you also must take the square root of the left side.
+ - sqrt (x-4) = y
y = sqrt (x - 4)
and y = - sqrt (x - 4)
Answer:
Step-by-step explanation:
Let the numbers be x and y.
<u>The equations are:</u>
<u>Add up the equations to eliminate y and solve for x:</u>
- x - y + 2x + y = 2 + 13
- 3x = 15
- x = 15/3
- x = 5
<u>Now find the value of y:</u>
- y = x - 2
- y = 5 - 2
- y = 3
