solve. 3(x-6)-2(2x+3)=14
Answer:
x=-38
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
3(x−6)−2(2x+3)=14
(3)(x)+(3)(−6)+(−2)(2x)+(−2)(3)=14(Distribute)
3x+−18+−4x+−6=14
(3x+−4x)+(−18+−6)=14(Combine Like Terms)
−x+−24=14
−x−24=14
Step 2: Add 24 to both sides.
−x−24+24=14+24
−x=38
Step 3: Divide both sides by -1.
−x
−1
=

The function f(x) = 40sin(0.1x + 12) + 50 represents the number of items, f(x), made in a factory each day for x days. The data used to generate the function was collected over 90 days.
Graph the model, and then use the graph to determine on which day each event occurred.
The first day production exceeds 70 items is day
The last day in the first cycle that production exceeds 70 items is day

A water hose discharges water at a rate of 45 gallons per minute. Which graph has a slope
that best represents this rate?
Answer:
F
Step-by-step explanation:
F is the correct graph because the bottom is for minutes and if you drag your finger on the 1 minute you meet 45 which is how many gallon per minute. and if you go to 2 minutes you meet with 90 which is 45+45=90 and 45 is one minute and 90 is 2 minutes.
srry if that was complicated
Hope this helps you!
The graph which best represents the rate of discharge given is graph F.
It is given that discharge rate of a water hose is 45 gallons per minute.
We have to check which graph has a slope that best represents this rate.
What do you mean by discharge rate of water ?
Discharge rate of water is defined as the rate at which drainage water is released from a site.
As per the question ;
The rate of discharge = 45 gallons per minute
So,
We can say that ;
When x = 1 minute
y = 45 gallons
We can conclude that F is the correct graph because the x-axis is for minutes and if you check at time 1 minute you get 45 gallons at the y-axis which shows the no. of gallons per minute.
Thus , the graph which best represents the rate of discharge given is graph F.

The graph shows equivalent ratios.
Leah plots a point to show a fourth equivalent ratio. If the y-value of Leah’s point is 36, what is the x-value?
Answer:
32
Step-by-step explanation:
on the graph, i noticed that it was switching from (8,9) to (16,18) so I knew that it was increasing the x-value by 8 for each point plotted, and the y-value was increasing by 9 for each point plotted, therefore the answer would be (32,36)
Answer:
32
Step-by-step explanation:
because
4(3x-8)-4 = 24
12x-32-4= 24
12x-36 = 24
12x = 60

What methods did she use and in what order did she use them?
Answer:
C
Step-by-step explanation:
Given: AE = BD; CD = CE
Prove AC = BC
Step-by-step explanation:
Funny question!
AE=BD
A= BD/E
Then,
CD=CE
D=E
therefore, A=BE/E (SINCE, D=E)
So, A=B
or, AC= BC (multiplying by C)

2. What are the angle measures of the triangle?
Answer:
Answer A is the correct option.
Suzanne bought 6 paint sets. Each set contains the same number of brushes. She has 18 brushes. Write and solve an equation to determine the number of paint brushes that came in each paint set. Explain the strategy that you used to solve the equation.
Answer:
3
Step-by-step explanation:
Given that:
The number of paint sets, Suzanne bought= 6
As each set contains the same number of brushes.
Let x be the number of brushes each set contains.
So, the total number of brushes in 6 sets = 6x.
It is given that the total number of brushes she has is 18, which is equals to 6x.
So, the required equation is
[tex]6x=18[/tex]
[tex]\Rightarrow x=\frac {18}{6}[/tex]
[tex]\Rightarrow x=3.[/tex]
Hence, the number of paint brushes each set contains is 3.
