Step-by-step explanation:
(f ◦ g)(3) = f(g(3))
Each of the coordinate pairs for g correspond to ...
(x, g(x))
Then g(3) can be found by looking for the pair that has 3 in the first location. That ordered pair is ...
(3, 4)
so we know that g(3) = 4.
Now, we know that f(g(3)) = f(4). This tells us to look for the ordered pair in the f relation that has 4 as its first value. That ordered pair is ...
(4, 9)
so we know that f(4) = 9.
__
In summary, ...
(f ◦ g)(3) = f(g(3)) = f(4) = 9

Jorge gives an equal number of marbles to 6 friends. Which could be the total number of marbles he gave to his friends? (Answer choices 15,33,56,60)
Answers
Answer:
D. 60
Step-by-step explanation:
Since the question stated that the number of marbles given out to his 6 friends were equal, we are certain that the total number of marbles is a factor or multiple of 6.
The only other assumption here is the number of marbles given has to be whole number. This means we just have to go through the answer choices and pick the one that is a multiple of 6.
A. 15 - This is wrong as 15 is not a multiple of 6.
B. 33 - This is wrong as 33 is not a multiple of 6.
C. 56 - This is wrong as 56 is not a multiple of 6.
D. 60 - This is CORRECT as 60 is a multiple of 6.
If Jorge gives each of his friends 10 marbles each, it would bring the total number of marbles to be 60.

O {XIXER, x > 3)
O XIXER,X>7)
Answers
Answer:
The solution set is {x : x ∈ R, x > 3} ⇒ C
Step-by-step explanation:
The solution set of the inequality x > a is {x : x ∈ R, x > a}The solution set of the inequality x < a is {x : x ∈ R, x < a}The solution set of the inequality x ≥ a is {x : x ∈ R, x ≥ a}The solution set of the inequality x ≤ a is {x : x ∈ R, x ≤ a}Let us solve the question
∵ x - 5 > -2
→ Add 5 to both sides of the inequality
∴ x - 5 + 5 > -2 + 5
∴ x > 3
→ By using the first rule above
∴ The solution set is {x : x ∈ R, x > 3}
In parallelogram STUV, find the measure of TS.
Answers
Answer:

Step-by-step explanation:
well we know that STUV is a parallelogram (given)
so by properties of a parallelogram we know that opposite sides are congruent (in other words equal)
so we have that
VU=TS
and we know that VU=123.8 cm (given)
so TS=123.8

Answers
Answer:
Independent-samples t-test.
Step-by-step explanation:
We are looking for the appropriate design for testing the significance of the difference between the means.
Now, there is a parametric test known as the Independent Samples t Test and what this test does is that it compares the mean of two independent groups in order to find out whether there is statistical evidence that the related population mean is significantly different.
Thus, the test to be used here is Independent-samples t-test.
Write an equation of the line that passes through (-1,4) and is perpendicular to the line shown.
Answers
Answer:
y= -3/4x - 4Step-by-step explanation:
To write an equation that is perpendicular to a given line, take the negative reciprocal of the given slope. the given slope is 4/3, so the negative reciprocal is -3/4.
Using slope-intercept form of a linear equation, y=mx+b substitute in -3/4 for "m" the slope.
y=-3/4x+b
Now you need to "b" the y-intercept using the given point (-4,-1). Substitute the values in the equation. -1=-3/4(-4)+b simplify
-1= 3 + b subtract 3 for both sides
-4=b
substitue -4 for b. Now you have y= -3/4x - 4 this is your answer.

Which unit rate is equivalent to 17 miles per gallon? (5 points)
Question 1 options:
1) 3 gallons
_________
51 miles
2) 51 miles
______
3 gallons
3) 34 miles
_____
4 gallons
4) 4 gallons
______
34 miles
Answers
Answer:
The answer would be option 2) 51 miles/3 gallons.
Step-by-step explanation:
First, every 17 miles needs 1 gallon. If you add 17 more miles, it'll be 34 miles and you'll need a 2nd gallon, so you can already eliminate options 3 and 4. If you add another 17 miles and a gallon, it'll give you 51 miles 3 gallons. Option 1 would not be the answer because if you did 3/51, you'll get a whole different answer in decimals. So the only other option to choose from is option 2.

how do I Translate the following verbal statement into an algebraic equation and then solve: Krystal bought a nightstand on sale for $170, which was one-fourth of the original price. What was the original price of the nightstand
Answers
Answer:the original price is $680
Step-by-step explanation:
1/4(x)=170
4×1/4(x)=4×170
x=$680
The original price of the nightstand is $680.
What is an equation?In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
Given that, Krystal bought a nightstand on sale for $170, which was one-fourth of the original price.
Let the original price of nightstand be x.
Now, 1/4x =170
x=170×4
x=$680
Therefore, the original price of the nightstand is $680.

Matthew dropped a tennis ball off the roof of 100 foot tall building. The objects height (y) is modeled by the equation below. At what time (t) does the ball hit the ground? Round your answer to the nearest tenth
Answers
Answer:
2 seconds later
Step-by-step explanation:
Since the required equation is lacking, let the equation modeled by the height be expressed as y = -16t² + 64
The ball hits the ground at y =0. Substitute y = 0 into the expression and find t;
Since y = -16t² + 64
0 = -16t² + 64
16t² = 64
t² = 64/16
t² = 4
t = ±√4
t = 2 and -2
Time cannot be negative, hence the ball hits the ground 2 seconds later.
Note that the equation used was assumed. Similar solution can be applied for any given equation.

Answers
Hi sorry for the late response, I know the assignment was due at 5pm today but anyway here is the answer.
System:
d= 5(0.75-t)
d= 20t
20t = 3.75 -5t
Define Variables:
d = how far Carol Skied
t = time it took Carol to go up/down
Solve:
20t = 3.75 -5t
20t + 5t = 3.75 -5t + 5t
25t = 3.75
25t/25 = 3.75/25
t = 0.15
Now we plug in the time into the Distances:
20t = 3.75 - 5t
20(0.15) = 3.75 - 5(0.15)
3 = 3.75 - 0.75
3 = 3

no solution
Step-by-step explanation:
1/2(4x+14)=2(x-7)
Multiply both sides by 2.
4x + 14 = 4(x - 7)
4x + 14 = 4x - 28
Subtract 4x from both sides.
14 = -28
Since 14 = -28 is a false statement, there is no solution for this equation.
