Choose the point slope form of the equation below that represents the line that passes through the points (-3, 2) and (2, 1)

mihalych1998 [28]

Answer:

$\large\boxed{y-1=-\dfrac{1}{5}(x-2)}$

Step-by-step explanation:

The point-slope form of a line:

$y-y_1=m(x-x_1)$

m - slope

(x₁, y₁) - point

The formula of a slope:

$m=\dfrac{y_2-y_1}{x_2-x_1}$

We have the points (-3, 2) and (2, 1). Substitute:

$m=\dfrac{1-2}{2-(-3)}=\dfrac{-1}{5}=-\dfrac{1}{5}$

$y-1=-\dfrac{1}{5}(x-2)$

Tickets to a local basketball team's games cost $12 each. Brendon and Ed each bought tickets to four games. How much did they sp

den301095 [7]

Answer:

total amount spent is $96 altogether on tickets

Step-by-step explanation:

Step 1

Derive the expression for the total amount Brendon spent on the tickets as follows;

total amount=cost per ticket×number of tickets bought

where;

cost per ticket=$12

number of tickets Brendon bought=4

replacing;

total amount=(12×4)=48

total amount spent by Brendon=$48

Step 2

Derive the expression for the total amount Ed spent on the tickets as follows;

total amount=cost per ticket×number of tickets bought

where;

cost per ticket=$12

number of tickets Ed bought=4

replacing;

total amount=(12×4)=48

total amount spent by Ed=$48

Step 3

Total amount spent altogether=total amount spent by Ed+total amount spent by Brendon

replacing;

Total amount spent altogether=(48+48)=96

They spent Derive the expression for the total amount Brendon spent on the tickets as follows;

total amount=cost per ticket×number of tickets bought

where;

cost per ticket=$12

number of tickets Brendon bought=4

replacing;

total amount=(12×4)=48

total amount spent is $96 altogether on tickets

Two solutions of the polynomial equation are given. Use synthetic division to find any remaining solutions.

liubo4ka [24]

Answer:

The remaining solutions are -7 and 3.

Step-by-step explanation:

The synthetic division is shown in the attachment. After dividing the first two found factors from the polynomial, the remaining quadratic is ...

x^2 +4x -21 = 0

Its rational roots will be factors of -21, and the sum of their opposites will be 4. Knowing that 21 = 3·7, we can guess that the remaining roots are -7 and 3. The synthetic division confirms that. (A graph also confirms it.)
