Answer:
Add the equations in order to solve for the first variable. Plug this value into the other equations in order to solve for the remaining variables.
Point Form:
(
4
,
1
)
Equation Form:
x
=
4
,
y
=
1
7^(3x)=9 take the natural log of both sides
3xln7=ln9 divide both sides by 3ln7
x=ln9/(3ln7)
x≈0.376
First find the measure of x.
12x + 3x = 90
15x = 90
x = 6
Plug in x into ∠PVQ, which is 12x.
12(6) = 72
m∠PVQ = 72°
Answer:
x=2,y=-5
Step-by-step explanation:
−4x+3=x−7
x=2; y=−5
