<h2>
Answer: y + 7 = -3 (x - 1)</h2>
Step-by-step explanation:
The slope of the line (m) = (y₂ - y₁) ÷ (x₂ - x₁)
= (- 7 - 8) ÷ ( 1 - (- 4))
= - 15 ÷ 5
= - 3
We can now use the point-slope form to write the equation for this line:
y - y₁ = m(x - x₁) where (x₁ , y₁) = (1, -7)
y - (-7) = -3 ( x - 1)
y + 7 = -3 (x - 1)
Answer:
a) x = 5
b) x = 4
Step-by-step explanation:
a) 
= 9.5
3x+4 = 9.5(2)
3x = 19-4
x = 15/3
x = 5
b) 
= 5
7+2x = 5(3)
2x = 15-7
x = 8/2
x=4
No
5*x= x (correct)
5*1=5 (incorrect)
When I say correct or incorrect it means that it does/doesn’t match 5x+1
Answer:
6√3
Step-by-step explanation:
6^2+x^2=12^2
36+x^2=144
-36 -36
x^2=108
x=6√3
Answer:
g(f(4)) = -3
Step-by-step explanation:
f(x)=x-7
g(x) = x
g(f(4))
f(4) = 4-7
f(4) = -3
g(-3) = -3
