First equation: -8x+7y=-17
Second equation: y=2x+1
Take the value of y from the second equation, as y is already isolated, and plug it in for y in the first equation. Simplify and solve for x.
-8x+7(2x+1)=-17
-8x+14x+7=-17
6x+7=-17
6x=-24
x=-4
Take the value of x we just found and plug it into the first equation. Solve for y.
-8(-4)+7y=-17
32+7y=-17
7y=-49
y=-7
Hope this helps!! :)
Answer:
The first one is the right answer go go go
Answer: No triangles can be formed.
Step-by-step explanation: Given Dimensions = 15cm , 7cm , 5cm
Inequality property = Sum of 2 shorter sides ≥ 3rd side
∴ 7 + 5 is not greater than 15
∴<u><em> No triangles can be formed.</em></u>

Answer:
y=x^2-13x+42
Step-by-step explanation:
y=(x-6) times (x-7)
y=x^2-7x-6x+42
collect like terms
y=x^2-13x+42
There you go
