Answer:
Jenny's age = 8 yr
Sam's age = 17 yr
Step-by-step explanation:
Let x = Jenny's age now
then x + 9 = Sam's age now
x - 5 = Jenny's age 5 years ago
x + 9 - 5 = x + 4 = Sam's age 5 years ago
4(x - 5) = x + 4
4x - 20 = x + 4
3x = 24
x = 8 = Jenny's age now
x + 9 = 8 + 9 = 17 Sam's age now
Check: 5 yrs ago Jenny was 3 and Sam was 12
4(3) = 12, so the answer is correct.

A triangle has two angle measures of 20 degrees and 30 degrees. Find the third angle. This triangle is a(n) ________ triangle
Question 2 options:
A. acute
B. obtuse
C. right
D. it does not make a triangle
Answer:
Obtuse
Step-by-step explanation:
x = missing angle
20+30+x=180
50+x=180
x=130
90<130
Thus, the triangle is obtuse
Brian earns $5 per hour babysitting. He makes a graph and plots what he
earns for different numbers of hours. He places the number of hours he
works on the x-axis and his earnings on the y-axis. What is the slope of the
line that Brian graphs?
Answer:
The slope of the line is 5
Step-by-step explanation:
When we talk of the slope of a straight line graph, we refer to the rate at which the values on the y-axis changes as a ratio of the changes we have on the x-axis
Now, from the question, number of hours is placed on x-axis, while we have the amounts on the y-axis
having $5 per hour means the rate of change of what is earned to number of hours worked is 5 and this is the slope of the line
In three days, the chickens on Nigel's farm can lay 33 eggs. How many eggs will they lay in 11 days?
Answer:
Eggs laid by chicken in 11 days = 121 eggs
Step-by-step explanation:
Eggs laid by the chickens in 3 days = 33
Average rate at which the chickens are laying the eggs = [tex]\frac{33}{3}[/tex]
= 11 eggs per day
At the same rate number of eggs laid by the chickens in 11 days = Rate × Number of days
= 11 × 11
= 121 eggs
Therefore, eggs laid by chicken in 11 days = 121 eggs

Which is a true statement about the transformation shown?
Answer:
A
Step-by-step explanation:
It's not a reflection because then it would be flipped and M and N would switch places
It's a translation and everything is the same length in terms of each other so
A translation with the pre and after image being congruent

Graph this: y = 2sIn(x) - 3
Insert picture of graph
Answer:
We have the function:
f(x) = 2*sin(x) - 3
To graph this type of functions is useful to understand the parts of the function.
A general one is written as:
g(x) = A*sin(w*x + p) + M
where:
A is the amplitude
w is the angular frequency.
p is the phase
M is the midline.
Then in this case we have an amplitude of 2, an angular frequency of 1, a phase of 0 radians and the midline y = -3
Now we can evaluate the function in different points and (knowing how a sine function behaves) connect them, the graph will look something like this:

Find x and y in the given figure
Answer:
x= 70°, y=40°
Step-by-step explanation:
2x=140
x= 70
y= 180-140= 40
140 + y = 180
y = 180 - 140
y = 40
2x + 40 = 180 (Angle Sum Property)
2x = 180 - 40
2x = 140
x = 140/2
x = 70
X = 70
Y = 40
Using the graph, predict the y-value when the x-value is 13
A) 17
B) 18
C) 19
D) 20
9514 1404 393
Answer:
D) 20
Step-by-step explanation:
Each point marked on the graph is 3 units higher and 2 units to the right of the one before. The last dot is at x=9, so a dot at x=13 will be 2×2=4 units to the right. At the same rate of increase, it will be 2×3=6 units higher than 14.
The y-value is predicted to be 20 at x=13.
The Sugar Sweet Company will choose from two companies to transport its sugar to market. The first company charges $7500 to rent trucks plus an additional fee of $150.25 for each ton of sugar. The second company charges $7143 to rent trucks plus an additional fee of $175.75 for each ton of sugar.
Answer:
14 tons of sugar
$9603.5
Step-by-step explanation:
For what amount of sugar do the two companies charge the same?
What is the cost when the two companies charge the same?
Let
x = ton of sugar
Company A:
7500 + 150.25x
Company B:
7143 + 175.75x
1. Equate company A and company B
7500 + 150.25x = 7143 + 175.75x
7500 - 7143 = 175.75x - 150.25x
357 = 25.50x
x = 357/25.50
x = 14 tons of sugar
2. Cost when both companies charge the same
Company B:
7143 + 175.75x
= 7143 + 175.75(14)
= 7143 + 2460.5
= 9603.5
Company B = $9603.5
Company A:
7500 + 150.25x
= 7500 + 150.25(14)
= 7500 + 2103.5
= 9603.5
Company A = $9603.5
