What is the question you just said Can someone answer this what's the question
Substitute y = 1/5 x + 1 into x + 5y = -15
x + 5y = -15
x + 5(1/5 x + 1) = -15
x + x + 5 = -15
2x = -20
x = -10
Plug in x = -10 into y = 1/5 x + 1
y = 1/5 (-10) + 1
y = -2 + 1
y = -1
(-10 , -1)
Answer is the last one
(-10 , -1)
First, distribute 2 to all terms within the parenthesis
2(4x + 5) = 8x + 10
8x + 10 > 7x + 20
Isolate the x. Treat the > like a equal sign. Subtract 7x and 10 from both sides
8x (-7x) + 10 (-10) > 7x (-7x) + 20 (-10)
Simplify
8x - 7x > 20 - 10
x > 10
x > 10 is your answer
hope this helps
