Answer:

Infinity

Step-by-step explanation:

Slope = y2 - y1/x2 - x1

Given

x1 = 9

y1 = -3

x2 = 9

y2 = -8

Therefore

Slope = -8 -(-3) /9 - 9

= -8 + 3 /9 - 9

= -5/0

= infinity

-52 times the difference between a number and 14 is equal to the number plus 3
xenn [34]
X=number looked for
we have this equation:
-52(x-14)=x+3
we solve this equation:
-52x+728=x+3
-52x-x=3-728
-53x=-725
x=-725/-53=725/53 ≈13,68

Solution: 725/53

To check:
the difference between 725/53 and 14=725/53  - 14=(725-742)/53=-17/53
-52 times the diference is= -52(-17/53)=884/53
The number plus 3=725/53 + 3=(725+159)/53=884/53

Morgan is throwing a pizza party. She has 1 7/8 ​ pounds of cheese available and she needs 1/5 pound of cheese to make each pizz
Karolina [17]

We have been given that Morgan is throwing a pizza party. She has 1 7/8 ​ pounds of cheese available and she needs 1/5 pound of cheese to make each pizza. We are asked to find the number of full pizzas that Morgan can make with the amount of cheese she has.

To solve our given problem, we will divide total amount of cheese by amount of cheese used to make each pizza.

\text{Number of pizzas}=1\frac{7}{8}\div \frac{1}{5}

\text{Number of pizzas}=\frac{15}{8}\div \frac{1}{5}

Now we will convert our division problem into multiplication problem by flipping the 2nd fraction.

\text{Number of pizzas}=\frac{15}{8}\times \frac{5}{1}

\text{Number of pizzas}=\frac{75}{8}

\text{Number of pizzas}=9\frac{3}{8}

We are asked to find the number of full pizzas and we can see that Morgan can make 9 full and \frac{3}{8} pizzas.

Since there are 9 full pizzas, therefore, Morgan can make 9 full pizzas with the amount of cheese she has.
