Answer:
-3, 5/2
Step-by-step explanation:
What are the roots of the function y = 4x2 + 2x – 30?
To find the roots of the function, set y = 0. The equation is 0 = 4x2 + 2x – 30.
Factor out the GCF of : 2, so the equation becomes 0 = 2(2x2+x-15)
Next, factor the trinomial completely. The equation becomes: 0=2(x+3)(2x-5)
Use the zero product property and set each factor equal to zero and solve.
x+3=0 2x-5 = 0
x = -3, 5/2
The roots of the function are -3, 5/2.
Hope this helped!
First put the equation into standard form by isolating y:
y=-0.5x+5
To convert x to have no coefficients, the coefficient is really 1, so multiplying everything by -2 and you get
-2y=x-10
Answer:
y=1x+8
Step-by-step explanation:
- The best way to remember the formula is y=mx+b aka (your mom's ex bf)
- Just by looking at the slope you can automatically tell it's moving by one so in your formula, 'm' is the slope.
- Add 1x to replace 'm' or you can leave x alone because x is already one, your choice.
- b is the indication on where your slope started in the y-axis.
- In this case, by looking at the y-axis on the graph, the slope starts at 8 so that will be your b.
- Therefore, your answer is y=1x+8
A The surface area of the smallercan is 80%of the surface area of the larger can
Let us say that:<span>
P = present value
F = future value
i = interest rate
n = period
P = F / [ (1 + i ) ^n ]
P = 200000 / [ (1 + 0.011) ^6 ]
P = 187293.65
