Write the equation of the line that is PARALLEL to y = -4x + 5 and passes through the point (-2,-1)
Answer: y = -4x-9
Step-by-step explanation:
parallel slope means it's the same slope as the given equation
y+1=-4(x+2)
y+1 = -4x-8
y = -4x-9
A parent is using a garden hose to fill up a small inflatable pool for her young child. The
pool has a capacity of 90 gallons. She turns the water off after 5 minutes, but leaves the
hose in the pool for another 3 minutes before putting it away.
In this situation, the relationship between the gallons of water in the pool and the 8
minutes since the parent started filling the pool can be seen as a function.
1. In that function, which variable is independent? Which one is dependent?
Answer:
The independent is the 90 gallons and the dependent is the 8 minutes.

What is 160% of 40? Four students solved this problem and their work is shown below. Choose the student whose work is correct. Cam's work. 16 times 40 = 00 .00 + 640 = 640. Gitana's work. 1.6 times 40 = 00. 00 + 640 = 64.0. Naoko's work. 0.16 times 40 = 00. 00 + 640 = 6.40. Sanjay's work. 160 times 40 = 00. 00 + 6400 = 6400.
Answer:
Gitana's work is correct
Step-by-step explanation:
Divide 40 with 100 then multiply it by 160
40 ÷ 100 × 160 = 64
Answer:
Gitana is correct.

Sheila's class recycles a total of 6 pounds of paper in 2
weeks. After 5 weeks, how many pounds of paper will
Sheila's class have recycled?
Answer:
It should be 15 pounds
Step-by-step explanation:
If you divide 5 weeks (the amount you need) by 2 weeks (the current ratio 6:2) then you get 2.5. Lastly just multiply 6 pounds to it (the other part of the ratio/ pounds per 2 weeks)

In triangle OPQ, p = 38 cm, q = 29 cm and Angle O=39º. Find the length of o, to the nearest
centimeter.
Answer:
The length of o is 24 centimeters
Step-by-step explanation:
In Δ OPQ
∵ Side p is opposite to ∠P
∵ Side q is opposite to ∠Q
∵ Side o is opposite to ∠O
→ To find side o we must use the cosine rule
∴ o = [tex]\sqrt{p^{2}+q^{2}-2(p)(q).cos(O) }[/tex]
∵ p = 38 cm
∵ q = 29 cm
∵ m∠O = 39°
→ Substitute them in the rule to find o
∴ o = [tex]\sqrt{(38)^{2}+(29)^{2}-2(38)(29).cos(39)}[/tex]
∴ o = 23.92008154
→ Round it to the nearest centimeter (whole number)
∴ o = 24 centimeters
∴ The length of o is 24 centimeters
Help! GHJ Café sells Medium and large coffees to locals in Downtown Dallas. If 7 medium cups and 10 large cups of coffee are sold, the café makes $68.75 in sales. If 10 medium and 15 large cups are sold, the total sales is $101.25. How much does a large cup of coffee sell for at GHJ Café?
Answer:
Large cup cost $4.25
Step-by-step explanation:
Medium: x
Large: y
Constraints:
7x + 10y = 68.75
10x + 15y = 101.25
Isolate y variable:
(7x + 10y = 68.75) * -10 ===> -70x - 100y = -687.50
(10x + 15y = 101.25) * 7 ===> 70x + 105y = 708.75
____________________
add the two equations 5y = 21.25
divide by 5 y = 4.25

FIND what was the mistake
and what is the correct answer
Answer:
Step-by-step explanation:
Instead of dividing both sides by 5, it is multiplied
5x + 3 = 6 {Subtract 3 from both sides}
5x + 3 - 3 = 6-3
5x = 3 {Divide both sides by 5}
5x/5 = 3/5
x = 3/5
log x = log(x + 3) - log(x - 1)
First note that log(x) is defined only for x > 0; log(x + 3) for x > -3; and log(x - 1) for x > 1. So if we find any solutions x ≤ 1, these will be extraneous.
Condense the right side:
log(x) = log((x + 3) / (x - 1))
Let b be the base of the logarithm. Then writing both sides as powers of this b simplifies the equation to
b^log(x) = b^log((x + 3) / (x - 1))
x = (x + 3) / (x - 1)
Solve for x :
x (x - 1) = x + 3
x ² - x = x + 3
x ² - 2x - 3 = 0
(x - 3) (x + 1) = 0
x - 3 = 0 or x + 1 = 0
x = 3 or x = -1
We throw out x = -1 because it's less than 1, so the only (real) solution is x = 3.

Have to find x and y . Please help!
Answer:
Step-by-step explanation:
x can be anything so let’s use 0, 1, 2, and 3 for x values
to find the y values, we just plug in the x values into the equation
when x = 0
y = 5/4(0) -2
y = 0 -2
y = -2
(0, -2) (x = 0, y = -2)
when x = 1
y = 5/4(1) -2
y = 5/4 -2
y = 5/4 -8/4
y = -3/4
(1, -3/4) (x = 1, y = -3/4)
when x = 2
y = 5/4(2) -2
y = 10/4 -2
y = 5/2 -4/2
y = 1/2
(2, 1/2) (x = 2, y = 1/2)
when x = 3
y = 5/4(3) -2
y = 15/4 -2
y = 15/4 -8/4
y = 7/4
(3, 7/4) (x = 3, y = 7/4)
Answer:
Table shown below
Step-by-step explanation:
Table of Values
We are given the function:
[tex]\displaystyle y=\frac{5}{4}x-2[/tex]
And it's required to fill the table of values for x and y with the condition that there are only integers.
Given the expression has a denominator of 4, to ensure there are no decimals in the results, we select values of x that are multiple of 4.
Select the values: {-4,0,4,8}
Now calculate the corresponding values of y.
x=-4
[tex]\displaystyle y=\frac{5}{4}(-4)-2=-5-2=-7[/tex]
y=-7
x=0
[tex]\displaystyle y=\frac{5}{4}(0)-2=0-2=-2[/tex]
y=-2
x=4
[tex]\displaystyle y=\frac{5}{4}(4)-2=5-2=3[/tex]
y=3
x=8
[tex]\displaystyle y=\frac{5}{4}(8)-2=10-2=6[/tex]
y=8
