Answer:
In vertex form we have y = (x + 2)^2 - 10
Step-by-step explanation:
x^2+4x-6=0 is in standard form; we want it in the form y - k = a(x - h)^2.
Complete the square within x^2+4x-6=0
We get x^2 + 4x - 6 = 0 => x^2 + 4x + 4 - 4 - 6, or
y = (x + 2)^2 - 10
Comparing this to y = (x - h)^2 - 10, we see that the vertex is at
(h, k) : (-2, -10)
Answer:
Month 4
Step-by-step explanation:
Given : Jordan is saving for a new laptop that costs $325.
Equation: d=80+75m
To Find: Which is the first month in which Jordan will have saved enough money to buy the laptop?
Solution:
Equation:
where d is the total amount he has saved so far.
m shows the number of months he has been saving.
Now we are given that he needs to save $325.
So, To find the first month in which Jordan will have saved enough money to buy the laptop
Substitute d = 325 in the equation:
Thus,the first month in which Jordan will have saved enough money to buy the laptop is Month 4.
Answer:
1/2
Step-by-step explanation:
ln(a) = x means e^x = a
If we plug in sqrt(e) for a, we get:
e^x = sqrt(e)
sqrt (a) = a^(1/2)
That means x = 1/2
Area formula for rectangles: L x W
Answer: 3 x 2a + 3 x 5 = 3 x 2a x 5
You know that the expressions are equivalent, because when you solve for a you get a = 5/8 or 0.625
