Answer:

29.25 / 29 1/4 MPH (Miles Per Hour)

Step-by-step explanation:

2/3 of an hour equals 40 minutes, so 19 1/2 miles is 40 minutes. 20 minutes is 1/3 of an hour, which is the missing amount of 2/3. Divide 19 1/2 miles by 2 to get 9 3/4 miles (which is how far Ms. Sanchez can go in 20 minutes). multiply by 3 to get 29 1/4 Miles Per Hour.

Write the equation of the line in slope-intercept form.

Natali5045456 [20]

Answer:

y = - 10x + 40

Step-by-step explanation:

Two points

$(0,40), (4, 0)$

Slope

$m=\frac{0-40}{4-0} =-\frac{40}{4} =-10$

Equation:

$y-40=-10(x-0)$

$y-40=-10x$

$y=-10x+40$

What is the remainder when the polynomial 5x2+10x−15 is divided by x + 5? Enter your answer in the box.

otez555 [7]

ANSWER
The remainder is
$60$

EXPLANATION

Let

$p(x) = 5 {x}^{2} + 10x - 15$

We shall apply the remainder theorem to obtain the remainder when
$p(x)$
is divided by
$x + 5$

According to the remainder theorem, if a polynomial
$p(x)$
is divided by
$x - a$
then the remainder is
$p(a)$

So we set
$x + 5 = 0$

and solve for
$x$

to obtain,

$x = - 5$

We now substitute -5 into the given polynomial to find the remainder.

$p( - 5) = 5 {( - 5)}^{2} + 10( - 5) - 15$

This gives us,

$p( - 5) = 5(25) - 50 - 15$

This will simplify to,

$p( - 5) = 125 - 50 - 15$

$p( - 5) = 60$

Therefore the remainder is
$60$
