Answer:
Step-by-step explanation:
Vertex form: 
where:
is the vertex
is some constant
Given:
- vertex = (-4, -1)
- point on parabola = (-2, -3)
Substitute given values into the formula to find :
Therefore, the equation of the parabola is:
Answer:
Initial value is the y- intercept and the change per month is the slope.
- The slope is $25, which is an increase rate per month.
- The y- intercept is $525, which is the investment amount.
<u>The model function is:</u>
Answer:
7.5 years.
Step-by-step explanation:
Use A = 1400(1+0.02)^7.5
The 1400 is the starting money. The 1 is a constant. The 0.02 is the 2% in decimal form. And the 7.5 is years. I found that by just continually increasing it until it hit 1624.
Hope this helps
Answer:
Step-by-step explanation:
3(x+4)-6=5x+5
distribute 3 through the parenthesis (3 times x + 3 times 4)=3x+12
3x+12-6=5x+5
subtract 12-6
3x+6=5x+5
Move the variable to the left and change the sign
3x-5x+6=5
collect like terms
3x-5x=5-6
-2x=5-6
divide both sides by -2
x=1/2
The ansser is 2x10^-3 sorry for the mistake i’m french
