A line in point slope form is y = mx + b
m = the slope
b = y-intercept
So far our line looks like: y = -3/5x + b
Let's plug -5 into x and -3 into y to solve for b
-3 = -3/5(-5) + b
Let's multiply -5 by -3/5
-3 = 3 + b
Subtract 3 from both sides.
-6 = b
Our line is: y = -3/5x - 6
The sum of 2 numbers is 25. The sum of their reciprocals os 1/4. Determine the two numbers.
Answer:
5, and 20
Step-by-step explanation:
5+20=25
reciprocal of 5 is 1/5 and reciprocal of 20 is 1/20 so 1/5=4/20 and 4/20 + 1/20 = 5/20. 5/20 = 1/4

(100 POINTS) Write the particular equation of this transformed cosine graph. (Hint: Try to find the best point to center the sinusoidal axis.)
Answer:
y= - 3cosx - 2
Step-by-step explanation:
Our max here is at 1, and the minimum is at - 5
The distance between the x-axis and these points are 1 and 5. 5 + 1/2 = 6/2 = 3, our amplitude. But let's double check. Our middle point is - 2 so...
- 5 - (- 2) = - 5 + 2 = - 3
The amplitude is rather - 3.
f(x) = Acos(Bx + C) + D
Using this we know B = 0, D = - 2 (the middle point), C = 0, and A = - 3 (amplitude). B = 0, and C = 0, as there is no horizontal/vertical shift
f(x) = Acos(Bx + C) + D
f(x) = - 3cosx + (- 2)
f(x) = - 3cosx - 2
Answer:
y= - 3cosx - 2

Jill can run 20 miles in
three hours at a steady
rate. How many minutes
will it take her to run
five miles?
Answer:
45 minutes
Step-by-step explanation:
Change 3 hours to minutes
1 hours = 60 minutes
3 hours = 180 minutes
Using proportions
20 miles 5 miles
------------- = ----------------
180 minutes x minutes
Using cross products
20x = 5* 180
20x =900
Divide each side by 20
20x/20x = 900/20
x =45
45 minutes
Answer: 45 minutes
Step-by-step explanation: 20 miles in 180 minutes, 5 miles is 1/4 of 20 miles so you divide 180 by 4 which gives you 45

If Kim reduces the weekly number of hours she works by one-fourth and her current weekly income is $520.00, what is her new weekly income?
Answer:
$390 you divide 520 by 4 so 520/4=130 now we subtract 130 from 520, 520-130=390
Step-by-step explanation:
Solving this question requires basic arithmetic formula and fractions.
New weekly income = $390
Let's call the number of hours kim works weekly as "x"
If she reduces this number of hours by one-fourth and her current weekly income is $520, then it means the amount to be deducted is;
[tex]\frac{1}{4}[/tex] × $520 = $130
Thus, her new weekly income will be;
$520 - $130 = $390

Is 4x + 9 equivalent to 2(2x+5) -1?
Answer: Yes!
Step-by-step explanation:
1. So you have: 4x+9 and 2(2x+5)-1
2. Simplify the 2nd expression: 2(2x+5) -1 = 4x + 10 - 1 = 4x+9
4x+9 = 4x+9
Answer:
Yes
Step-by-step explanation:
Set them equal to each other to see. If they are, then you should come out with the answer 0 = 0.
4x + 9 = 2(2x + 5) - 1
4x + 9 = 4x + 10 - 1
0 = 0

What is 3/5 written as a percent?
A. 6%
B. 30%
C. 60%
D. 167%
Answer:
60%
Step-by-step explanation:
1/5 equals 20 % and thus 3/5 is 20 % multiplied by 3 so 60 %
Answer: "Percent" or "%" means "out of 100" or "per 100", Therefore x% can be written as
x/100
.
We can then rewrite this as: 60%.

Step-by-step explanation:
Two numbers, both greater than 23, have HCF 23 and LCM 644. The sum of the numbers is:
Answer: 253
Step-by-step explanation:
First, we have two numbers A and B.
We know that all numbers can be written as a product of prime numbers.
And the HCF of A and B is 23
Then we can write:
A = 23*a
B = 23*b
(remember that 23 is a prime number)
Where a and b are larger than 1.
Now we know that the least common multiple between them is 644.
Notice that the primes that conform a can not be the same as the ones for b, because in that case, the HCF would not be 23.
Now to find a and b we can compute:
644/23 = 28.
28 = a*b
Now let's write 28 as a product of prime numbers:
a*b = 28 = 4*7 = 2*2*7
Then we can define:
a = 2*2
b = 7.
Our two numbers are:
A = 23*2*2 = 92
B = 23*7 = 161
A + B = 92 + 161 = 253
The sum of the two numbers would be:
253
Assume the two numbers be [tex]x[/tex] and [tex]y[/tex]
Given that,
HCF of [tex]x[/tex] and [tex]y[/tex] = 23
so,
The numbers could be written as:
23[tex]x[/tex] and 23[tex]y[/tex]
We know that,
LCM of 23[tex]x[/tex] and 23[tex]y[/tex] = 644
We also know that,
LCM × HCF = The product of two numbers
∵ 644 × 23 = 23[tex]x[/tex] × 23[tex]y[/tex]
So, by solving them we get;
14812/529 = [tex]x[/tex] × [tex]y[/tex]
∵ [tex]x[/tex] × [tex]y[/tex] = 28
If we prime factorize 28, we get
28 = 2 × 2 × 7
This gives us,
[tex]x =[/tex]23 × 2 × 2 = 92
[tex]y =[/tex] 23 × 7 = 161
Thus, the sum of the two numbers = 92 + 161 = 253
