Answer:y=-3
Step-by-step explanation:5(y+2/5)=-13
so first you simplify both sides of the equation
(5)(y)+(5)(2/5)=-13
then you distribute
5y+2=-13
then you subtract 2 from both sides
5y+2-2=-13-2
5y=-15
then u divide both side by 5
5y=-15
5 5
y=-3
I am having trouble with this question
Answer:
C
Step-by-step explanation:
The equation of a line is usually written in the form of y=mx+c, where m is the gradient and c is the y-intercept.
Gradient=
[tex] \frac{y1 - y2}{x1 - x2} [/tex]
[tex]m = \frac{ - 12 - ( - 15)}{ - 5 - ( - 1)} \\ m = \frac{15 - 12}{1 - 5} \\ m = - \frac{3}{4} [/tex]
y= -¾x +c
To find c, substitute a coordinate.
When x= -1, y= -15
[tex] - 15 = - \frac{3}{4} ( - 1) + c \\ c = - 15 - \frac{3}{4} \\ c = - 15\frac{3}{4} [/tex]
Thus the equation of the graph is
[tex]y = - \frac{3}{4} x - 15 \frac{3}{4} [/tex]
Therefore the answer is C.
Explain 15 is not a prime factor
15 is not a prime factor as it is divided by 1,3,5 and 15.
Additional information:
Prime numbers are those numbers which can only be divided by itself .for instance:1,2,3,5,7 ,11,13 etc.
Composite number s are those numbers which can be also divided by other numbers,For instance: 4,6,8,10 etc

The equation of the line in this graph is y = __x +___.
Answer:
The line equation is y = 1.5x + 3
Fill the first space with '1.5' and the second with '3'
Step-by-step explanation:
The generic model for a line equation is:
y = ax + b
To find the parameters 'a' and 'b', we can use two points of the graph in the equation.
Using the point (0, 3), we have:
3 = 0*a + b
b = 3
Using the point (-2, 0) and the value of b above, we have:
0 = -2*a + b
2a = 3
a = 1.5
So the line equation is y = 1.5x + 3

Aquarium one contains 4.6 gallons of water. Louise will begin filling aquarium one at a rate of 1.2 gallons per minute.
Aquarium two contains 54.6 gallons of water. Isaac will begin draining aquarium to at a rate of 0.8 gallons per minute.
After how many minutes will both aquariums contain the same amount of water?
Answer:
25
Step-by-step explanation:
4.6 + 1.2g = 54.6 -.8g
1.2g + .8g = 54.6 - 4.6
2g = 50
g = 25
Answer:
Hideki is draining a 45-gallon aquarium at a rate of 15 gallons per minute. Let's solve for the initial value of the linear function that represents thissituation. => 45 gallon aquarium at rate of 15 gallons per minute.
=> 45 gallon / 15 gallon = 3 minutes. Therefore with the rate of 15 gallons per minutes, Hideki will be able to finish the 45 gallon aquarium in 3 minutes.

A house is listed for sale at $235,000, but the listing does not include square
footage of the house. Based on the comps, the line of best fit is
y=0.06x + 60.5. If the price is fair, what size (in square feet) should the house
be?
A. 2850 ft^2
B. 2900 ft^2
C. 20,000 ft^2
D. 2350 ft^2
Answer:
Option B.
Step-by-step explanation:
If the cost of the house (y) is in thousands and area of the house is x ft².
Cost of the house is modeled by the equation given,
y = 0.06x + 60.5
By substituting the values in the line of best fit,
235 = 0.06x + 60.5
0.06x = 235 - 60.5
0.06x = 174.5
x = [tex]\frac{174.5}{0.06}[/tex]
x = 2908.33 ft²
x ≈ 2900 ft²
Therefore, Option B will be the correct answer.

Line segment AB was dilated to create line segment A'B' using the dilation rule DQ,0.15.
What is x, the distance between points A and A'?
2.4 units
4.8 units
13.6 units
14.4 units
Answer:
13.6
Step-by-step explanation:
The measure of the segment AQ is related to the measure of the segment A'Q by the dilation factor as follows:
dilation factor = A'Q/AQ
AQ = A'Q/dilation factor
Replacing with data:
AQ = 2.4/0.15 = 16
Then, the distance between points A and A' is
x = 16 - 2.4 = 13.6
The distance between points A and A' is 13.6 units
Dilation of coordinatesDilation is a way of changing the position of an image on an xy-plane.
The measure of the segment AQ is related to the measure of the segment A'Q by the dilation factor. Hence'
scale factor = A'Q'/AQ
Given the following
A'Q' = 2.4
Scale factor = 0.15
Substitute
AQ = 2.4/0.15
AQ = 16
x = 16 - 2.4
x = 13.6
Hence the distance between points A and A' is 13.6 units

im not sure but I think the answer is -4
Answer:
4
Step-by-step explanation:
Take away the negative signs:
-80/-20
80/20
Now, divide normally.
80 ÷ 20 = 4
Since a negative number divided by another negative number is positive, the quotient is still 4.
Therefore, the simplified fraction is 4.

If θ is an angle in standard position and its terminal side passes through the point (-9,-5), find the exact value of
cot
θ
cotθ in simplest radical form.
Answer:
Step-by-step explanation:9/5 is the answer
(-5)^2 + (-9)^2 =c^2
25 + 81 = c^2
106= c^2
Sqr rt 106 = c
By using trigonometric relations, we will see that:
cot(θ) = 9/5.
How to get the cotangent?We know that if an angle's terminal side passes through the point (x, y), then we can write the tangent as:
tan(θ) = y/x
In this case, we know that the terminal side passes through (-9, -5), then the tangent is:
tan(θ) = -5/-9 = 5/9
And the cotangent is the inverse of the tangent, then:
cot(θ) = 1/tan(θ) = 9/5.

The volume of oblique cone, to the nearest tenth is,
⇒ 142.3 units³
What is the volume of an object?The area that any three-dimensional solid occupies is known as its volume. These solids can take the form of a cube, cuboid, cone, cylinder, or sphere.
Since, WE know that,
Volume of oblique cone = (1/3) x π x r² x h
Given that,
Radius (r) = 4 units
Height (h) = 8.5 units
Thus:
Volume of oblique cone = (1/3) x π x 4² x 8.5
Volume of oblique cone = 1/3 × 3.14 × 16 × 8.5
Volume of oblique cone = 142.3 units³

∠a and ∠b are complementary angles. ∠a measures 24∘. What is the measure of ∠b?
Answer:
66°
Step-by-step explanation:
Complementary angles are those that add up to 90 degrees. Since a and b are complementary, we can write:
∠a + ∠b = 90
We already know that ∠a = 24°, so we can plug this in:
24 + ∠b = 90
∠b = 90 - 24 = 66°
Thus, the answer is 66°.
Michael made a spinner to use in a game. He tested the spinner by spinning it 4 times. The pointer landed on 1 each time. What do these results suggest about the spinner?
A. It is probably a fair spinner. The probability of spinning a “1” is 0.25.
⊝
B. It is probably a fair spinner. The probability of spinning a “1” 4 times is 0.25 × 4, which equals 1.
⊝
C. It is probably not a fair spinner. The probability of spinning a “1” on all 4 spins is about 0.004.
⊝
D. It is probably not a fair spinner. The probability of spinning a “1” on all 4 spins is less than 0.0001.
Please help
Answer:
C
Step-by-step explanation:
If The probability of spinning a “1” is 0.25, then the probability of spinning 4 ones is:
0.25*0.25*0.25*0.25 = 0.25^4 ≈ 0.004
(the four events are independent)
The pointer landed on 1 each time, which probability is very low. So, we can conclude that the spinner is not fair.
