the answer is 9 because 7=y so , 7+2=9
Answer:
Problem 1:
a. x=2
b. x=3
c. x=1
Problem 2:
A multiplication equation to hold the table true:
A division equation to hold the table true:
Step-by-step explanation:
Given in problem 1:
(a). The equation is 
It holds true for all values of 
.
Let us say 
,
which is greater than 1.
(b). The equation is 
It holds true for all values of 
.
Let us say 
which is less than 1.
(c). The equation is 
It holds true for only 
.
Let us say 
,
which is equal to 1.
Problem 2:
A multiplication equation to hold the table true:
A division equation to hold the table true:
Therefore these are the values which hold true to the equation in problem 1 and 2.
Answer:
a + b = 5
Step-by-step explanation:
To solve this system of equations, we can use a strategy called elimination, which is when we get rid of a variable by adding/subtracting two equations.
Firstly, we want to make sure the absolute value of the coefficients that equal.
Lets eliminate b:
4a + 6b = 24
Multiply both sides by 2:
8a + 12b = 48
We also have:
6a - 12b = -6.
Now lets add that with
8a + 12b = 48
-> 6a + 8a + 12b - 12b = 48 -6
-> 14a = 42
-> a = 3
Now that we know a, lets plug it into one of our original equations:
4(3) + 6b = 24
12 + 6b = 24
6b = 12
b = 2
Finally, add the two values we found:
a+b = 2+3= 5
Answer:
4 donuts per minute/(donutes is that a typo?)
Step-by-step explanation:
if a bakery can make 60 donuts in 15 minutes, that is 60 donuts/15 minutes.
to reduce this fraction, the top and bottom can be divided by 15 to get 4 donuts/1 minute.
Graph 3 is the answer. Choose a point on the line. Go down by 3. Then go to the right by 5.
