What is the equation of the line that passes through the point (-5,-6) and has a slope of 3/5?
Answer:
y=3/5x-3
Step-by-step explanation:
First, put the slope in point-slope form: y-y1=x(x-x1)
y+6=3/5(x+5)
Distribute 3/5 to (x+5) and simplify.
y+6=3/5x+3
y=3/5x-3
f(0) =4 and f(2)=8 slope intercept form of the equation of the line
Answer:
y=2x+4 or f(x)=2x+4
Step-by-step explanation:
f(0)=4 is (0,4) and f(2)=8 is (2,8)
first, find the slope using the equation y2-y1/x2-x1
8-4/2-0
4/2
2
now, take one of the points, and put it into the equation y2-y1=m(x-x1) (m is slope)
take (0,4) for example
y-4=2(x-0)
y-4=2x
y=2x+4
y=f(x)
so, substitute as
f(x)=2x+4

True or false:triangle angle some theorem is when all of them interior (inside)angles of a triangle add up to 180°?
Answer:
true
Step-by-step explanation:
The sum of interior angles is 180 degrees (Triangle Angle Sum Theorem). All interior angles of a triangle are more than 0° but less than 180°. The bisectors of all the three interior angles intersect inside a triangle at a point called the in-center, which is the center of the in-circle of the triangle.

37st term: 9, 3, -3, -9, -15
Answer:
Step-by-step explanation:
The first term (a) = 9
the 37th term is what we want (n = 37)
d = - 6
t_37 = 9 + (n - 1) * (-6)
t_37 = 9 + 36 * - 6
t_37 = 9 - 216
t_37 = - 207

Bouncing Baby Company sells their cribs for the following amounts to stores
Number of Cnbs

Price
$1320
50
S6600
Which of the following statements about the price of the cribs are true if the price remains proportional to the number of cribs Select TWO that apply.
A. 6 cribs cost $600
B. 22 anos cost $2640
C. 40 cribs cost $5280
D. 55 cribs cost $7920
E. 80 cribs cost $10.500
F. 250 cribs cost $11 880
Answer:
Option C
Step-by-step explanation:
Since, Price of cribs (P) are proportional to the proportional to the number of cribs (N) sold,
P ∝ N
P = kN
Here 'k' is the proportionality constant
To get the value of proportionality constant,
Since, value of 10 cribs is $1320
1320 = k(10)
k = 132
Therefore, equation will be
P = 132N
Option A
If number of cribs = 6
P = 132(6) = $792
False.
Option B
For N = 22
P = 132(22) = $2904
False.
Option C
For N = 40
P = 132(40) = $5280
True
Option D
For N = 55
P = 132(55) = $7260
False
Option E
For N = 80
P = 132(80)
= $10560
False
Option F
For N = 250
P = 132(250)
= $33000
False
If the given options have been written correctly only one option, Option (C) is correct.

Given,
Cherie accepted a job through an employment agency
The job pays $1,100 weekly.
The agency charges 22% of her first three months, pay.
22% of 1100 we have to calculate.
First we have to convert 22% to decimal
22/100=0.22
0.22×1100=242
Now for three months we need to calculate.

The area of a rectangular painting is 8428 cm² If the width of the painting is 86 cm, what is its length?
9514 1404 393
Answer:
98 cm
Step-by-step explanation:
Area is the product of length and width. Fill in the given numbers in the formula and solve for length:
A = LW
8428 cm² = (86 cm)L
L = 8428 cm²/(86 cm) = 98 cm . . . . . divide both sides by 86 cm
The length of the painting is 98 cm.
A manager in a call center needs to determine how many agents to schedule next week.
Based on previous data, she expects to get 7,940 calls next week. The following conditions
apply:
• On average, call center agents can handle seven calls an hour.
• The call center is open for 10 hours, 5 days a week.
Full-time agents work 40 hours per week, but are only on calls for 35 hours a week.
Part-time agents work 20 hours a week, but are only on calls 17 hours per week.
Answer:
Number of calls expected in next week by manager = 7940
Average Number of calls that call center agent will attend in an hour =7 calls
It is also given that, Call center remain open for 10 hours 5 days a week.
Also, it is given that, full time agents work 40 hours a week but are only on call for 35 hours per week ,Part time agents work 20 hours a week but are only on calls 17 hours per week .
⇒Number of hours worked by full time agents × Number of calls attended in an hour × Number of full time agents + Number of hours worked by Part time agents × Number of calls attended in an hour × Number of Part time agents ≤ 7940
⇒35 × 7×Number of full time agents +17 × 7 ×Number of Part time agents ≤ 7940
Option A
⇒35×15×7+17×7×15
= 3675+1785

Option B
⇒35 ×7×20+17×7×7

I got the answer 55 so see what is close to 55
Answer:
2 ^ 3 + 4 * 8 = 40
Step-by-step explanation:
So going by the order of operations, PEMDAS,
There are not parenthesis so we can skip that part.
exponents on the other hand we have 2^3. Don't be fooled. It's not 2 * 3. What you have to do is multiply 2 by itself 3 times. So 2 * 2 * 2 = 8. Step one Done!
The M in PEMDAS is multiplication! So we solve that part next! 4 * 8 = 32. Step 2 Done!
Now for the final step, for A in PEMDAS you have to add both sums together. 8 + 32 = 40
Final answer: 40

4. Elena's account balance with her parents is
-$5.50. She adds a certain amount of
money to her balance by mowing the lawn.
Elena now has an account balance less than
$20. Determine a possible amount she
earned mowing the lawn. Then interpret the
solution. (Example 1) moll end to bi
Answer:
-$5.50>x>$20
Elena has more than -$5.50 but less than $20.
Step-by-step explanation:
Ok, so the question says that Elena has -$5.50 in her account. That means that she owes someone ( the bank) $5.50.
Elena then mows the lawn which may have paid off her debt. But we don't know that for sure.
All they give us is that Elena has less than $20 in her bank account.
So your answer may look like this:
-$5.50>x>$20
Elena has more than -$5.50 but less than $20.
Elena earned, amount more than -$5.50 and less than $20 by mowing the lawn.
What is Inequality?If two real numbers or the algebraic expressions are related by the symbols “>”, “<”, “≥”, “≤”, then the relation is called an inequality.
For example, x>3 (x should be greater than 3)
Given,
Account balance of Elena with her parents = -$5.50.
Which means she is in debt of $5.50.
Elena then adds a certain amount of money to her balance by mowing the lawn,
which may have paid off her debt, that is not sure.
But,
Account balance of Elena after mowing the lawn is more than - $5.50 less than $20.
Let the money Elena earned by Elena earned mowing the lawn = x
Then,
Possible amount she earned mowing the lawn = -$5.50 < x <$20.
Hence, Possible amount Elena earned mowing the lawn is
between -$5.50 and $20 = -$5.50 < x < 20.
