Answer:  y=2.5x+2.5

Step-by-step explanation:

The equation of the line in Slope-Intercept form is:

y=mx+b

Where "m" is the slope and "b" is the y-intercept.

Since we know that the line passes through the point (2,7.5) and (-1,0), we can find the slope with this formula:

m=\frac{y_2-y_1}{x_2-x_1}

Substituting values, we get:

m=\frac{0-7.5}{-1-2}\\\\m=2.5

In order to find the y-intercept, we can substitute the slope and the point (-1,0) into y=mx+b and then solve fo "b":

0=(2.5)(-1)+b\\\\0=-2.5+b\\\\b=2.5

Then, the equation of this line in Slope-Intercept form is:

 y=2.5x+2.5

Find a polynomial with a degree of 3 and zeros -3,3,5
Aliun [14]

Answer:

f(x) = x³ - 5x² - 9x + 45

Step-by-step explanation:

Given x = a, x = b are the zeros of a polynomial, then

(x - a), (x - b) are the factors and f(x) is the product of the factors.

Here the zeros are x = - 3, x = 3 and x = 5, thus

(x + 3), (x - 3) and (x - 5) are the factors and

f(x) = (x + 3)(x - 3)(x - 5) ← expand the first pair of factors using FOIL

     = (x² - 9)(x - 5) ← distribute

    = x³ - 5x² - 9x + 45

8 3/8 = r- 2 1/3 how do i solve this equation by finding out what r is.
BaLLatris [955]
First, convert your mixed numbers into improper fractions, so 8+3/8=69/8 and 2+1/3=7/3. Now you have 69/8=r-(7/3). Now, add 7/3 to both sides, so (69/8)+(7/3)=r. Now, just add your fractions, so (69/8)+(7/3)=207/24+56/24=(207+56)/24=263/24. If you need to, this can be converted back into the mixed number 10+23/24.
