Find the discriminate
a = 4, b = -21, c = -18
to keep from getting "mixed up", evaluate the discriminant first ...
b<sup>2</sup> - 4ac = (-21)<sup>2</sup> - 4(4)(-18) = 729
sqrt(729) = 27
x = (21 +/- 27)/8
x = -3/4, x = 6
since the discriminant is a perfect square, the original quadratic will factor ...
4x<sup>2</sup> - 21x - 18 = 0
(4x + 3)(x - 6) = 0
x = -3/4, x = 6
Answer:729
Step-by-step explanation: Use the values of a, b and c to find the discriminant. Which is 729

The graph of F(x), shown below, has the same shape as the graph of G(x) = x^3, but it is shifted down 2 units. What is its equation?
gil borrows $8000 for college expenses. he will pay a total of $2280 back in interest after 6 years. what was his interest rate
Answer:
R = 41.8129%/year
Equation:
r = (1/t)(A/P - 1)
Calculation:
Solving our equation:
r = (1/6)((8000/2280) - 1) = 0.41812865
r = 0.41812865
Converting r decimal to R a percentage
R = 0.41812865 * 100 = 41.8129%/year
The interest rate required to get a total amount, principal plus interest, of $8,000.00 from simple interest on a principal of $2,280.00 over 6 years is 41.8129% per year.
Step-by-step explanation:
Answer:
I believe it is 4.75 %
Step-by-step explanation:
2,280 × 100 = 228,000
228,000 / 8,000 = 28.5
28.5/6 = 4.75 %
JJ decides to leave a tip that is 15% of the original price for his meal. How much should he leave as tip for the $5.50 cheeseburger and $2.50 milkshake? Express your answer to the hundredths place?
Answer: $9.20
Step-by-step explanation: To get the answer, you add both the cost and multiply it by .15. Then you add the product to the number you got adding the cost of the food.
Answer:
$1.20
Step-by-step explanation:
He has to leave 100% of the cost which is $5.50 + 2.50 or $8.00.
He wants to leave 115% of the $8 he has to leave.
So you set it up like
x/8 = 115/100
Then you solve for x
8(115) = 920
920/100 =9.2
So he will leave $9.20.
It then asks for just how much the tip is that he will leave so
9.2 - 8 = 1.2
So the tip is $1.20.
If y = 45 when x = 180, what is the y when x= 90
Answer:
24.5
Step-by-step explanation:
Since 180 is double 90 divide 45 by 2 and you'll get 24.5

The graph of a linear function f passes through the point (-2,-10) and has a slope of 5/2 what is the zero of f ?
Answer:
Check the explanation.
Step-by-step explanation:
As the graph of a linear function f passes through the point (-2,-10) and has a slope of 5/2.
As the slop-intercept form is given by:
[tex]y = mx+b[/tex]
where m is the slope and b is the y-intercept.
substituting the values (-2, -10) and m = 5/2 in the slop-intercept form to determine y-intercept.
[tex]y = mx+b[/tex]
[tex]-10=\frac{5}{2}\left(-2\right)+b[/tex]
[tex]-\frac{5}{2}\cdot \:2+b=-10[/tex]
[tex]-5+b=-10[/tex]
[tex]-5+b+5=-10+5[/tex]
[tex]b=-5[/tex]
And the equation of the line in the slope-intercept form will be:
[tex]y = mx+b[/tex]
putting b = -5 and slope = m = 5/2
[tex]y = mx+b[/tex]
[tex]y=\frac{5}{2}x+\left(-5\right)[/tex]
[tex]y=\frac{5}{2}x-5[/tex]
Determining the zero of function.
As we know that the real zero of a function is the x‐intercept(s) of the graph of the function.
so let us determine the value of x (zero of function) by setting y = 0.
[tex]0=\frac{5}{2}x-5[/tex]
[tex]\frac{5}{2}x-5=0[/tex]
[tex]\frac{5}{2}x=5[/tex]
[tex]5x=10[/tex]
[tex]x=2[/tex]
Therefore, the zeros of the function will be:

What are the zeros or x-intercepts of the parabola?
A) (0, -1) and (0,5)
B (2,0) and (-9,0)
C (-1,0) and (5,0)
D (0,-5) and (-5,0)
Answer:
C
Step-by-step explanation:
x-intercepts , when y=0 are
(-1,0) and (5,0)
Answer:
C
Step-by-step explanation:
The zeros are also known as x-intercepts so it is the points on the x axis.
For x-intercepts the y is 0 so it is (-1,0) and (5,0)
hope this helped :)
