X+ y = 2....multiply by -2
2x + 5y = 16
--------------
-2x - 2y = -4 (result of multiplying by 2-)
2x + 5y = 16
-------------add
3y = 12
y = 12/3
y = 4

x + y = 2
x + 4 = 2
x = 2 - 4
x = -2

solution is (-2,4)

Isaac is making soft pretzel nuggets. His recipe says that, after he makes the dough, he should divide it into 8 equal pieces. T
Romashka-Z-Leto [24]

Answer:

The answer to your question is 192 pretzels

Step-by-step explanation:

Data

number of pieces = 8

length of each piece = 2 ft

length of each pretzel = 1 in

number of pretzels = x

Process

1.- Convert ft to in

                        1 ft --------------- 12 in

                         2 ft --------------- x

                         x = (2 x 12) / 1

                         x = 24 ft

2.- Divide the length of each piece by the length of each pretzel

                       24/1 = 24 pretzels per piece

3.- Multiply the number of pretzels per the number of pieces

                       24 x 8 = 192 pretzels

Elza [17]

Answer:

b and d

Step-by-step explanation:

Under a reflection in the x - axis

a point (x, y ) → (x, - y ) , then

the x- coordinate is 9 → b

the y- coordinate is - 1 → d

A softball has a volume of 1256π cubic inches. Find the radius of the softball.
RSB [31]
\bf \textit{volume of a sphere}\\\\
V=\cfrac{4\pi r^3}{3}~~
\begin{cases}
r=radius\\
------\\
V=1256\pi 
\end{cases}\implies 1256\pi =\cfrac{4\pi r^3}{3}
\\\\\\
1256\pi (3)=4\pi r^3\implies \cfrac{1256\pi (3)}{4\pi }=r^3\implies 942=r^3\implies \sqrt[3]{942}=r
