Answer:
y = 3x
Step-by-step explanation:
The general direct variation equation is y = kx.
If y = 15 when x = 5, then 15 = 5k and k = 3.
Then the specific direct variation equation is y = 3x

Answer:
1. c = 5.75b + 25
2. y = -1/3 + 5
3. y = -1/2 + 5
4. y = I can't tell what the numbers are from the photo, but (B) will be where the line is on the y axis of the graph.
Y = MX + (B)
Edit: Okay assuming the graph is going in the directions by one, meaning 1, 2, 3, or -1, -2, -3, and not any other sequence.
The answer for question will be y = 1/2x -1
The ratio of one side of ΔABC to the corresponding side of similar ΔDEF is 3:5. The perimeter of ΔDEF is 48 inches. What is the perimeter of ΔABC?
Answer:
28.8 inches
Step-by-step explanation:
We solve the above question using Proportion
The ratio of one side of ΔABC to the corresponding side of similar ΔDEF is 3:5.
ΔABC/ΔDEF = 3/5
Hence,
The perimeter of ΔDEF is 48 inches.
Let the perimeter of ΔABC = x inches
3/5 = x/48
Cross Multiply
5x = 48 × 3
x = 48 × 3/5
x = 28.8 inches
The perimeter of ΔABC is 28.8 inches

A school administrator claims that the average GPA of
the senior class is 3.53. You think that the average GPA
is greater than that, so you select a random sample of
100 seniors and calculate their average GPA. The
sample mean GPA is 3.70.
Using technology, you simulate selecting 100 SRS of
size n = 100 from a population of seniors for which the
mean GPA is 3.53. This dotplot shows the results.
O In one simulated SRS of 100 students, the average
GPA was = 3.45.
In one simulated SRS of 100 students, the
population mean GPA was u = 3.45.
There is a 1 out of 100 chance that the population
mean GPA is = 3.45.
O A majority of the sample of 100 students had a GPA
of r = 3.45.
Answer: In one simulated SRS of 100 students, the average GPA was x= 3.45

Show how to use substitution or elimination to solve the following system of equations. Write your solution as an ordered pair:
7x + y = 5 , 7x + y = -2
( , )
And please tell me if you used substitution or elimination. TYSM
Answer:
x=.5, y=-5.5
Step-by-step explanation:
7x+y=5, 7x+y=-2
Simplifing 7x+y=5 first
7x+y=5
y=-7x+5
Next, 7x+y=-2
7x+y=-2
y=-7x-2
Plugging in -7x+5 into y
-7x+5=-7x-2
-14x=-7
x=.5
Plugging .5 into y=-7x-2
y=-7(.5)-2
y=-3.5-2
y=-5.5
I used substitution if your couldn't tell

p-5 = 19
answer step by step & explain
Answer:
Step-by-step explanation:
Very simple.
p - 5 = 19
So to take out the -5 on that side, you must also do the same thing to the other side. So adding 5 in one side of the equal sign would mean you have to do the same thing on the other side of the equal sign.
SO:
p-5 +5 = 19+5
p = 24

Please find the area of the trapezoids.
By the way, the answer is NOT 10.5.
Answer:
42 square units
Step-by-step explanation:
Hello There!
The area of a trapezoid can be found using this formula
[tex]a = \frac{a + b}{2} h[/tex]
where a and b are bases and h is height
if you look at the graph we can see that the lines are counting by 2 units
knowing this we want to find the dimensions
the shown trapezoid has the following dimensions
a =2*2 or 4
b=5*2 or 10
h=3*2 or 6
having found this information we then plug it into the formula
[tex]a = \frac{4+ 10}{2} 6 \\ 4 + 10 = 14 \\ \frac{14}{2} = 7 \\ 7 \times 6 = 42[/tex]
so we can conclude that the area of the trapezoid is 42 square units

I know from the answer key that the answers are x=
3 \sqrt{10}310
and y=
2 \sqrt{10}210
but I'm not sure how to get there...
Answer:
x = 3/5√10
y = 2√10
Step-by-step explanation:
using the Pythagorean theorem:
y² = 7² - 3² = 49 - 9
y² = 40
y = 2√10
3/4.5 = y/5x
4.5y = 15x
substitute for y:
4.5(2√10) = 15x
15x = 9√10
divide both sides of the equation by 15:
x = (9√10)/15 = 3/5√10

A 180 pound weight is supported by two ropes each at 30 degrees, as shown in the figure. Find the tension in each rope.
Answer:
= 41.32N
To find N amount
You find the kg weight then times it by 10 then divide that amount by 1/2
So that 180pounds = 81.6466 x 10kg
x10 = 816.466
81.6466 / 2 = 40.8233
sin(30) = 40.8233/T
T = 40.8233/sin (30) = N / sin(30) = Tension = calculator = -41.3178070464 = 41.32 N
