9(12 ÷ 2)
Answer:
8 • 7 – 4 = 9 • 5 - 7.
Step-by-step explanation:
Given : 8 • 7 – 4 = ___________
To find : Which expression forms an equation with the given expression.
Solution : We have given 8 • 7 – 4 = ___________
First we solve the product
56 - 4.
52
Now we will check the 9 • 5 + 7
Solve the product 45 + 7 = 52.
So, the 8 • 7 – 4 = 9 • 5 - 7
Therefore, 8 • 7 – 4 = 9 • 5 - 7.
Answer:
x = 3 or x = -3
Step-by-step explanation:
x^2 -9 =0
x^2 = 9
x = 3 or x = -3
Step-by-step explanation:
if your question is
x²+5-14=0
x²-9=0
x²=9
x=√9
x=3 ans
Answer:
{-1, 1, 3}
Step-by-step explanation:
Given the function
y = (x + 1)/3
The domain are the input value x while the range are the output values given the input value x;
Given the domain {-4, 2, 8}
when x = -4;
y = (-4+1)/3
y = -3/3
y = -1
when x = 2;
y = (2+1)/3
y = 3/3
y = 1
when x = 8;
y = (8+1)/3
y = 9/3
y = 3
Hence the member of the range are {-1, 1, 3}
Answer:
4/9
Step-by-step explanation:
There are
4+3+2 = 9 balloons
The fraction that are red = red balloons/ total balloons
fraction red = 4 red/9 total
4/9
