Answer:
option D
Step-by-step explanation:
Jerry solved this equation:

In the first step , she multiplied 3 inside the parenthesis
1. 
In step 2, 3/4 is added on both sides
2. 
In step 3, we take LCD 12
3. 
In step 4, add the fractions
4. 
Here, 3 or 3/1 are same.

In step 5, to remove 3/1 we multiply both sides by 1/3.
Instead of multiplying 1/3 , Jerry made an error by multiplying 3/1


In step 5, he should have multiplied both sides by 1/3
Answer: a= 120
Step-by-step explanation:A = height times width, 10 times 12 is 120 :)
Answer:
x = 30
Step-by-step explanation:
Put in proportions
= 
Cross multiply and get 27x = 45 x 18
OR...
27x = 810.
THEN...
divide by 27 on both sides to get 30
x = 30
Answer:
(-2,4)
Step-by-step explanation:
The solution is the point at which the two lines intersect, (-2,4). That point is the only one that satisfies (works) in both equations:
y = x + 6
4 = -2 + 6
and
y = -0.5x + 3
4 = -0.5(-2) + 3
4 = 1 + 3
====
You can also solve it algebraically:
y = x + 6
y = -0.5x + 3
-0.5x + 3 = x + 6 [Use the value of y from the second equation in the first equation]
-1.5x = 3
x = -2
Use this is y = -2 + 6:
y = 4
(-2,4)
Answer:
From the given graph, it is clear that at x = 4, the corresponding y-value of the graph is y = 1
Therefore, we conclude that:
Step-by-step explanation:
Given:
A graph is given
To determine:
g(4) = ?
In other words, from the given graph, we need to determine the value of y at x=4
Finding g(4)
From the given graph, it is clear that at x = 4, the corresponding y-value of the graph is y = 1
Therefore, we conclude that:
