Factor 9r2 – 36r – 45.
Answer:
9(r - 5)(r - 1)
Step-by-step explanation:
9r^2 - 36r - 45
First, factor out 9
9(r^2 - 4r - 5)
Then you can factor what's inside the parentheses
9(r - 5)(r -1 )
1... 2(9n-1)+7(n+6)=-60
2... 11(4-6y)+5(13y+1)=9
Step-by-step explanation:
2(9n-1)+7(n+6)=-60
18n - 9 + 7n + 42 = -60
25n + 33 = -60
25n = -93
n = -3.72
11(4-6y)+5(13y+1)=9
44 - 66y + 65y + 5 = 9
-y + 49 = 9
-y = -40
y = 40
Answer:
Hello! I hope I’m correct!! :)
1. n = -4
2. y = 40
Step-by-step explanation:
Steps for the first equation.
Step #1. {we are solving for “2(9n-1)+7(n+6)=-60”}
[tex]18n-2+7n+42=-60[/tex]
Step #2. Simplify.
[tex]25n+40=-60[/tex]
Step #3. Subtract 40 {from both sides}
[tex]25n=-60-40[/tex]
Step #4. Simplify.
[tex]25n=-100[/tex]
Step #5. Divide both of the sides by 25. Which will be:
[tex]-\frac{100}{25}[/tex]
Step #6. Now divide (simplify) 100 & 25 which will give you the answer.
[tex]n=-4[/tex]
So for the first equation the answer is n = -4______________________________________
Now let’s solve the second equation.
Step #1. Expand
[tex]-y+49=9[/tex]
Step #2. Subtract 49 from both sides.
[tex]-y+49-49=9-49[/tex]
Step #3. Simplify.
[tex]-y=-40[/tex]
Step #4. Divide both sides by -1.
[tex]-40/-1[/tex]
Step #5. Simplify.
[tex]y=40[/tex]
And your answer to the second equation would be y = 40Sorry if this is incorrect but I hope this helps! If you have any questions about this, feel free to ask! Have a wonderful day! (≧∇≦)

It costs a flat rate of $35 for you to rent the ovens for as many hours as you want. You charge $29 per birthday cake. Your total costs is $470. Write and solve an equation to find how many birthday cakes were made.
470 = 29x+35
(x is number of birthday cakes)
subtract 35 from both sides,
435 = 29x
divide both sides by 29 to get x by itself,
15 = x
15 birthday cakes were made!
Answer:
35+29x=470 x=15 cakes
Step-by-step explanation:
3 35 represents rate for the oven and then 29 dollars per cake is the 29. 470 is the total amount of money you spent you just have to solve the equation from then to get x equals 15

The answer is 15.
Step-by-step explanation:
d = sqr. root of (x_2 - x_1)^2 + (y_2-y_1)^2}
= sqr. root of 7- - 2 ^ 2 + 3 - - 9 ^ 2
= sqr. root of 9 ^ 2 + 12 ^ 2
= sqr. root of 81 + 144
= sqr. root of 225

Step-by-step explanation:
Find the slope of the line given two points:
(8, 10) and (-7, 14)
A
m = -15/4
B
m = -24/1
с
m = -4/15
D
m = 4/15
Answer:
The answer is option CStep-by-step explanation:
The slope of a line given two points can be found by using the formula
[tex]m = \frac{ y_2 - y _ 1}{x_ 2 - x_ 1} \\[/tex]
where
(x1 , y1) and (x2 , y2) are the points
From the question the points are
(8, 10) and (-7, 14)
The slope is
[tex]m = \frac{14 - 10}{ - 7 - 8} = \frac{4}{ - 15} = - \frac{4}{15} \\ [/tex]

(F.IF.B.5) Michael’s family was traveling to visit prospective colleges. They drove to the closest college that interested him, took a tour, and then drove to another college a little farther from home. The graph shown represents this situation. What is the domain and range of the scenario?
Will give Braniliest if correct.
Answer:
domain ( 0-5) minutes
Range ( 0-300) miles
Step-by-step explanation:
Here, we are interested in writing the domain and range for the journey to the prospective colleges.
The range simply deaths with the distances in miles while the domain is the time in seconds.
The range is simply the smallest value on the y-axis to the largest value on the y-axis
The domain refers to the smallest value on the x-axis to the largest value of the x-axis
Kindly note that the domain and range does not refer to the labelings of the highest and lowest value on the axes but the highest and lowest value involved in plotting of the line in the graph.
From the graph, we can see that we have a range of; (0-300) miles while the domain is from (0-5) minutes

What can you do to the Smiley Face 1 to get Smiley Face 2?
Answer:
turn 180
Step-by-step explanation:
On her first day in a hospital, Kiri receives u1 milligrams (mg) of a therapeutic drug. The amount of the drug Kiri receives increases by the same amount, d, each day. On the seventh day, she receives 21 mg of the drug, and on the eleventh day she receives 29 mg.
a. write down an equation, in the terms u1 and d, for the amount of the drug that she receives on the seventh day.
b. write down an equation, in terms of u1 and d, for the drug that she receives on the eleventh day.
c. write down the value of d and the value of u1.
Answer:
a. 21 = u1 + 6·d
b. 29 = u1 + 10·d
c. d = 2, u1 = 9
Step-by-step explanation:
a. The given parameters are;
The amount of therapeutic drug Kiri receives on her first at the hospital = u1 milligrams
The amount of drug increase received by Kiri each day = d
The amount of drug Kiri received on the seventh day = 21 mg
The amount of drug she received on the eleventh day = 29 mg
Therefore, we have an arithmetic progression with the formula for the nth term given as follows;
aₙ = a₁ + (n - 1)·d
Where;
a₁ = u1
n = The number of terms
Therefore, for the 7th day, the amount of drugs she receives, which is 21 milligrams, is given as follows;
a₇ = u1 + (7 - 1)·d = u1 + 6·d = 21
The equation for the amount of drugs she receives in terms of u1 and d on the seventh day is given as follows;
21 = u1 + 6·d
b. For the eleventh day, the amount of drugs she receives, which is 29 milligrams, is given as follows;
a₁₁ = u1 + (11 - 1)·d = u1 + 10·d = 29
Therefore, the equation for the amount of drugs she receives in terms of u1 and d on the eleventh day is given as follows;
29 = u1 + 10·d
c. Therefore, we have two equations which are given as follows;
21 = u1 + 6·d................(1)
29 = u1 + 10·d..............(2)
Subtracting equation (1) from equation (2) gives;
29 - 21 = (u1 + 10·d) - (u1 + 6·d)
8 = 4·d
d = 8/4 = 2
d = 2
From equation (1), we have;
21 = u1 + 6·d = u1 + 6×2 = u1 + 12
21 = u1 + 12
21 - 12 = u1
∴ u1 = 9
d = 2, u1 = 9.

What is the equation of a line parallel to -5x + y= 2 that passes through the point with coordinates (-2,1)?
Answer:
y=5x+11
Step-by-step explanation:
You can solve this with the point-slope formula: y-y1=m(x-x1). The line is parallel; both slopes are equivalent.
First we have to rewrite the original equation, which is rewritten into y=5x+2 by subtracting -5x on both sides.
Next, plug in the coordinates we have into the point-slope formula (-2, 1), along with the slope from the original equation (5). To check, we can plug the coordinates back into the equation.
y-(1)=5(x+2)
y-1=5x+10
y=5x+11
Check:
(1)=5(-2)+11
1=-10+11

6x-4=3x+4 i need help doing this
Answer:
x=2.666 repeated
Step-by-step explanation: this is correct, pls mark brainliest. take -4 and add it to the other side(+4). 6x=3x+8. subtract 3x from 6x. 3x=8. take 3x and devide it on bolth sides. x=2.666 repeated
Answer:
x = 3/8
Step-by-step explanation:
6x -4 = 3x + 4
Step 1 - Add 4 on both sides
6x -4 = 3x + 4
+ 4 + 4
6x = 3x + 8
Step 2 - Subtract 3x on both sides
6x = 3x + 8
-3x -3x
3x = 8
Step 3 - Divide 3 on both sides
3x = 8
