7. Write an equation of the line that passes through the points (1, 4) and (-2, 10), in point-slope form.
Answer:
y = -2x + 6
Step-by-step explanation:
This has sort of the same concept as your earlier question
Use the equation y = mx + b
To find the slope, take the second y value and subtract the first y value. Then take the second x value and subtract the first x value. Divide the answers. You'd get -2 in this case. -2 would be your slope (m).
The substitute any set of x and y values (either (1, 4) or (-2, 10)) and the slope into y = mx + b. You'd get 6 as your y-intercept (b).
A group of friends hiked 7 miles in 2 hours at this same rate what is the total number of miles they can hike in 8 hours
GUYS I NEED HELP PLSSSSSS! Ive been working on this ALL day!
First, let's write what we know.
We can represent the number of students in the play from each class as L, G, and C. We know that L = 7, and if Gardener has 4 more students than Cho, then G = C + 4.
Then, taking the third line, we can write an inequality:
C < L < G
C < 7 < C + 4
C - 4 < 3 < C
3 < C < 7
If C is greater than 3 and less than 7 and is an integer, than means C is 4, 5, or 6.
Then, we need to find how many students are in the play.
C + L + G
C + 7 + C + 4
2C + 11
So we have our expression for the number of students in the play. Then, we need to find the total number of students. We know that 2C + 11 will be 30% of the total, so if T is the total, we can find T.
0.3T = 2C + 11
(Divide by 3/10 or multiply by 10/3 on both sides)
T = 20/3 C + 110/3
We know from before that C is 4, 5 or 6. We can plug these into our equation here to find which one produces a whole number.
T = 20/3 * 4 + 110/3
T = 190/3
T = 20/3 * 5 + 110/3
T = 210/3
T = 70
T = 20/3 * 6 + 110/3
T = 230/3
We can see here that only when C is 5 will the total be a whole number. That means Mrs. Cho has 5 students in the play. If Mrs. Gardner has 4 more than that, she has 9 students in the play in her class. We now need to figure out the number of student in her class.
The total students are Cho's, Logan's, and Gardner's classes added together. We know that Logan's class is 23 students, so if we subtract that from the total, we can see that Cho's and Gardner's class have 47 students. If Mrs. Cho has 24 students in her class, we can subtract that from the 47, so we know that Mrs. Gardner has 23 students in her class.

z varies jointly as x and y. z=60 when x=5 and y=6. find z when x = 7 and y=3
Answer:
z = 42
Step-by-step explanation:
The question can be answered in 2 steps as follows:
Step 1: Calculation of the constant of the variation
The equation for the joint variation can be given as follows:
z = cxy ................... (1)
Where;
z = 60
c = constant = ?
x = 5
y = 6
Substituting the values into equation (1) and solve c, we have:
60 = c * 5 * 6
60 = c * 30
c = 60 / 30
c = 2
Step 2: find z when x = 7 and y = 3
Since from Step 1 c = 2, we now use equation (1) and substitute the values into it to find z as follows:
z = 2 * 7 * 3
z = 42

how do you find the slope of (2,20)(4,40)(6,60)
9514 1404 393
Answer:
slope = 10
Step-by-step explanation:
Examination of the values shows you that each y-value is 10 times the corresponding x value. That means the slope is 10. (If the ratios were different, then the slope formula would need to be used. The fact that they are all the same means y is proportional to x.)
__
You can use the slope formula:
m = (y2 -y1)/(x2 -x1)
m = (40 -20)/(4 -2) = 20/2
m = 10
The slope is 10.
In the problem we’re supposed to find the value of x that makes ABC ~ RST I can’t figure it out can someone please help
Answer:
Step-by-step explanation:
if the triangles are similar then their sides are in proportion ( or you can think that they make equivalent fractions like 2/3 = 4/6 )
44/ (x+2) = 20/7 = 3x+1 /5 ( all of those are equivalent fractions)
use that [tex]\frac{a}{b} =\frac{c}{d}[/tex] is the same as a*d = b*c
[tex]\frac{44}{x+2} =\frac{20}{7}[/tex] is the same as 20(x+2) = 7*44
20x +40 = 308; subtract 40 from both sides
20x = 268; divide by 20 both sides
x= 13.4

O-is located on the left of -2
O - s located on the right of 0 and -2 Is located on the left of 0
is located on the left of0 and -2 is located on the right of 0
Answer:
A. -⅗ is located on the right of -2.
Step-by-step explanation:
-⅗ > -2 means -⅗ is greater than -2. This implies that, on a numberline, -⅗ is closer to 0 than -2.
-¾ and -2 are both located left of 0.
However, -⅗ which is closer to 0 than -2, would be located on the right of -2.

Anne is choosing a contractor. She has narrowed down her selection to two
companies and will base her decision on the likelihood that the job is done on
time and on budget. She uses online reviews to estimate the probabilities.
Which contractor should Anne choose to maximize the probability that the job will be done on time and on budget? Assume all events are independent.
Answer: A. Contractor A. The probability that both conditions are met is 0.93
Step-by-step explanation:
Probability of two independent events happening can be found by multiplying them.
Probability of A doing the job on time and on budget:
= Probability that job is done on time * Probability it is done on budget
= 0.97 * 0.96
= 0.93
Probability of B doing the job on time and on budget:
= 0.93 * 0.98
= 0.91
Contractor A has the better probability at 0.93 so should be chosen.
What are the constants in the expression 7r - 3 + 2s + 5
A 7, 3, 2, and 5
B -3 and 5
C 7 and 2
D 7, 2, and 5
Answer:
Option BStep-by-step explanation:
Definition of constants: Contants are numbers that have no variables.
To find the constants of the expression 7r - 3 + 2s + 5, simply look for numbers without variables. We can see that the constants are -3 and 5, which matches Option B.
Hence, Option B is correct.
Problem 2 Find all the divisors of the number 2,310. How do you know that you found them all?
9514 1404 393
Answer:
1, 2, 3, 5, 6, 7, 10, 11, 14, 15, 21, 22, 30, 33, 35, 42,
55, 66, 70, 77, 105, 110, 154, 165, 210, 231, 330, 385, 462, 770, 1155, 2310
Step-by-step explanation:
The trailing digit is 0, and the sum of digits is 6, so we know the number is divisible by 2, 3, 5. Dividing out those factors, we get a quotient of 77, which is 7×11. This means the prime factorization is ...
2×3×5×7×11 = 2310
There are 5 prime factors, each with an exponent of 1, so the total number of divisors is 2^5 = 32. We will have found them all when all 32 are listed.
1, 2, 3, 5, 6, 7, 10, 11, 14, 15, 21, 22, 30, 33, 35, 42,
55, 66, 70, 77, 105, 110, 154, 165, 210, 231, 330, 385, 462, 770, 1155, 2310
Of course, the pairwise products working toward the center from the ends of the list are all 2310.

What is Division?
A division is a process of splitting a specific amount into equal parts.
A unit rate means a rate for one of something.
We need to find the unit rate of 56 ounces for every 2 cans
To do this we need to divide Fifty six ounces with two.
56/2
Fifty six divided by two.
We get Twenty eight.

Ms. Hagan invested twice as much money in an account that pays 7% interest as she did in an account that pays 6% in interest. Her total investment pays her $1,000 a year in interest. How much did she invest at each rate?
Answer: She invested $5000 in an account that pays 6% interest and $10000 in an account that pays 7% interest.
Step-by-step explanation:
Let P be the initial amount she invested in an account that pays 6% interest.
Then, amount invested in other account = 2P
Simple interest = Principal x rate x time
After one year, for the first account,
Interest = P(0.06)(1) = 0.06P
For second account,
Interest = (2P)(0.07)(1)=0.14P
Total interest = [tex]0.06P+0.14P=1000[/tex]
[tex]\Rightarrow\ 0.20P=1000\\\\\Rightarrow\ P=\dfrac{1000}{0.20}\\\\\Rightarrow\ P=5000[/tex]
2P = 2(5000)=10000
Hence, She invested $5000 in an account that pays 6% interest and $10000 in an account that pays 7% interest.
At the interest rate of 6%, amount invested is; $5000
At interest rate of 7%, amount invested is; $10000
Let P be the initial amount that Ms. Hagan invested in the 6% interest account that
Since she invested twice as much in the 7% interest account as in the 6% interest account, then;
Initial amount invested in the 7% interest account = 2P
Formula for Simple interest is;
I = Principal × rate × time
Interest after 1 year for the 6% interest account is,
I_1 = P × 0.06 × 1
I_1 = 0.06P
Interest after 1 year for the 7% interest account is,
I_2 = 2P × 0.07 × 1
I_2 = 0.14P
Total investment pays her $1000 after a year. Thus;
0.06P + 0.14P = 1000
0.2P = 1000
P = 1000/0.2
P = $5000
Then amount initially invested in the 7% interest account = 2P = $10000
