Answer: All triangles are 180 degrees I don't know how to do the rest.
Substitute
4x+2=x-4
Then solve
3x=-6
x=-2
Substitute answer into an equation to find y
y=-2-4
y=-6
So you solution is:
(-2,-6)
Answer:
8 weeks of piano lessons in order to play 16 pieces
rate of 2:1
Step-by-step explanation:
14/7 is 2

<h2><u><em>xoxo, </em></u></h2><h2><u><em>your highness...</em></u> </h2>
Answer:
at least 19
Step-by-step explanation:
Let t represent the number of trees Jacob needs to trim. He wants ...
50(45) +120t ≥ 4500
120t ≥ 2250 . . . . . . . . . subtract 2250
t ≥ 18.75
Jacob must trim at least 19 trees to earn at least $4500.
The exponential function that shows San Francisco area after x years is y = 49(0.98)ˣ
<h3>What is an
exponential function?</h3>
An exponential function is in the form:
y = abˣ
Where a is the initial value of y and b is the multiplication factor.
Let y represent the land area of San Francisco after x years. Hence:
The city is only about 49 square miles in area, a = 49. It is losing 2% yearly, hence b = 100% - 2% = 0.98
The equation becomes y = 49(0.98)ˣ
