Show all work. Calculate and find the x-intercepts of the following function: f(x)=x^2+5x-36

We can do this by factoring: x^2 + 5x - 36, which is (x+9)(x-4)
We plug f(x) as 0, so (x+9)(x-4)=0, so x = -9 and x = 4
The x-intercepts are (-9, 0) and (4, 0).

Wilma saves $12,000 at the end of every six months for 10 years. Assume 10% compounded semiannually and find the present value.
yarga [219]
Here we use the formula for compound interest given by:
A=p(1+r/100*n)^(nt)
where:
A=amount=
p=principle=12000
r=rate=0.1
n=# terms=2
t=time=10 years
thus;
A=12000(1+0.1/2)^(2*10)
A=31839.6

Find the slope (0, -3) and (9, 0) PLEASE SHOW YOUR WORK, WILL MARK BRAINLEIST
Flura [38]
<h3>Answer: slope = 1/3</h3>

===================================================

Work Shown:

Use the slope formula to get

m = (y2 - y1)/(x2 - x1)

m = (0 - (-3))/(9 - 0)

m = (0 + 3)/(9 - 0)

m = 3/9

m = 1/3

----------------

Basically we subtract the y coordinates, and do the same for the x coordinates as well (subtract in the same order). Afterward, divide the two results. Reduce the fraction as much as possible.

A slope of 1/3 means we move up 1 unit each time we move to the right 3 units.

The slope being positive means the line goes uphill as you read from left to right.

Value of (–3/8) × (+8/15). <br><br> A. 11/15<br> B. 11/23<br> C. –1/5<br> D. –1/3
svet-max [94.6K]

ANSWER

The correct answer is C

EXPLANATION

We want to find the value of

- \frac{3}{8}   \times  \frac{8}{15}

This is the same as:

-  \frac{3}{8}  \times  \frac{8}{3 \times 5}

We cancel out the common factors to get:

-  \frac{1}{1}  \times  \frac{1}{1 \times 5}

We simplify to get:

-  \frac{1}{5}

The correct answer is C
