Answer:
Jenny´s age is 19 and her mother is 43.
Step-by-step explanation:
1. Plug in the first value of the set
41 is different from 62, so Jenny isn´t 12 years old.
2. Plug in the second value of the set
50 is different from 62, so Jenny isn´t 15 years old.
3. Plug in the third value of the set
59 is different from 62, so Jenny isn´t 18 years old.
4. Plug in the fourth value of the set
Therefore Jenny´s 19 years old.
5. Calculate Jenny´s mother age:
As the sum of their ages is 62 ages, we have the following equation
where
x=Jenny´s age
y=Jenny´s mother age
Therefore Jenny's mother age is 43 years old.

The first step that we must take before attempting to solve the problem is to understand what the problem is asking us to do and what is given to us to help accomplish that goal. Although it does not explicitly state that we must solve for t, this is usually what the problem statement would be asking if we just receive and expression like this. What is given to us to accomplish that goal is the expression
.
Now that we have completed that step, we can move onto the next part which is actually solving the problem. The next step that we should take when solving for the unknown, in this case t, is to subtract 4.9t from both sides.
<u>Subtract 4.9t from both sides</u>
Now that we got all of the t's to one side, let us isolate t completely and the next step that we should take is to subtract 0.72 from both sides.
<u>Subtract 0.72 from both sides</u>
The final step that we need to take to isolate t would be to divide both sides by 0.7 which would remove the coefficient from the unknown variable t and divide 0.7 from -0.42
<u>Divide both sides by 0.7</u>
Therefore, after fully narrowing down the solution we were able to determine that the solution of the unknown variable or t is equal to -0.6
Ok the first one.....No solution
The word problem......1.90
and the last one......U=4
I hope this helps!!! :)

By using BODMAS, any of the answers given is correct!
Answer:
B y = -1/2x + 7/2
Step-by-step explanation:
We know that it has a negative slope since the points go from the top left to the bottom right
We can eliminate A and D
The y intercept is where it crosses the y axis
It should cross somewhere between 2 and 4
C has a y intercept of 9 which is too big
Lets verify with a point
x = -4
y = -4(-4)+9 = 16+9 = 25 (-4,25) not even close to being near the points on the graph
checking B
y = -1/2 (-4) +7/2
= 2 + 7/2 = 11/2 = 5.5 it seems reasonable
