Answer:
k=-5
Step-by-step explanation:
For the points to be collinear any two pair must have the same slope
We find the slope of the 2nd and 3rd points
=1-2/-1--3
=-1/2
Now finding the slope of the 1st and any other point say point 3
1-3/-1-k=-½
-2/-1-k=-½
-4=-1(-1-k)
-4=1+k
k=-4-1
k=-5
PROOF
if the first point is (-5,3)
slope of point 1 and 2
=2-3/-3--5
=-1/2

Between 8.5% and 9.4% of the city's population uses the municipal transit system daily. According to the latest census, the city's population is 785,000. How many people use the transit system daily?
Given:
City's population= 785,000.
Calculating of city's population:
[tex]\to \bold{785000 \cdot 8.5 \% = 785000 \cdot \frac{8.5}{100}=785000 \cdot \frac{\frac{85}{10}}{100}}[/tex]
Calculating the complex fraction:
[tex]\to \bold{\frac{\frac{85}{10}}{100}, \text{write as 100 like} \ \frac{100}{1}}[/tex]
[tex]\to \bold{785000 \cdot \frac{ \frac{85}{10}}{100}=785000 \cdot \frac{\frac{85}{10}}{\frac{100}{1}}=785000 \cdot \frac{85}{1000}=66725}[/tex]
Therefore, [tex]\bold{8.5\% \ of\ 785000\ is\ {66725}}[/tex]
Calculating [tex]\bold{9.4\%}[/tex] of the city's population:
[tex]\to \bold{9.4\% (\frac{9.4}{100})}:\\\\\to \bold{785000 \cdot 9.4\% = 785000 \cdot \frac{9.4}{100}=785000 \cdot \frac{\frac{64}{10}}{100}}[/tex]
Calculating the complex fraction:
[tex]\to \bold{ \frac{\frac{94}{10}}{100}\ \text{write 100 as} \ \frac{100}{1}}\\\\\to \bold{785000 \cdot \frac{\frac{94}{10}}{100}=785000 \cdot \frac{\frac{94}{10}}{\frac{100}{1}}=785000 \cdot \frac{94}{1000}=73790}\\\\[/tex]
Therefore, [tex]\bold{9.4\%\ of\ 785000\ is\ {73790}}[/tex]
So, the final answer is "Between 66725 and 73790 people use the transit system daily".

how much would $500 invested at 5% interest compounded continuously be worth after 8 years?
a: $700
b:$709.58
c:$745.88
d.$738.73
Answer:
D
Step-by-step explanation:
We will need to use the compound interest formula:
A = P(1 + r)ⁿ
A = final amount
P = Initial amount
r = rate
n = time applied
Our equation will then look like this
A = 500(1.05)⁸
A = 738.72772

Can some one help mẹ pls....
Answer:
h(2) or h(g(4)) = -28
Step-by-step explanation:
g(t) = t - 2,
g(4) = 4 - 2,
g(4) = 2
h(t) = -3t³ - 2t,
h(2) = -3(2)³ - 2(2),
h(2) = -24 - 4,
h(2) or h(g(4)) = -28
Paul joins a gym. He paid $50 as an initial fee and then pays $30 each month. Set up and solve an equation to find out how long has he been at the gym if he has paid $260
Answer:
the equation you would use: y = 30x + 50
(x= months)
(y= cost)
then you would plug in the cost, 260, for y to get
260 = 30x + 50 --> 7 months
Step-by-step explanation:
I got the equation from the slope intercept form y = mx +b.
The 30 is the m, or slope, because you end up paying the same amount every month. The b value would be the 50 that he initially pays because that never changes.
Since you're given the y-value of 260, you just plug it in to your new equation of y = 30x + 50 to solve for x.
when solving the equation with the plugged in numbers, (260 = 30x + 50) first subtract 50 from both sides to get 210 = 30x,
then divide by 30 on both sides (to keep the equations equal to each other and find x) --> you should get 7
Therefore, Paul has been at the gym seven months if he has paid $260.

Answer: First Choice. no solution
Step-by-step explanation:
Given
5 (x + 1) ≤ 5x + 3
Expand parentheses and apply the distributive property
5x + 5 ≤ 5x + 3
Subtract 5x on both sides
5x + 5 - 5x ≤ 5x + 3 - 5x
5 ≤ 3
5 ≤ 3 is not true, therefore, there is no solution.

5(a-1)-15=3(a+2)+4 help
Answer:
a=15
Step-by-step explanation:
5(a−1)−15=3(a+2)+4
Use the distributive property to multiply 5 by a−1.
5a−5−15=3(a+2)+4
Subtract 15 from −5 to get −20.
5a−20=3(a+2)+4
Use the distributive property to multiply 3 by a+2.
5a−20=3a+6+4
Add 6 and 4 to get 10.
5a−20=3a+10
Subtract 3a from both sides.
5a−20−3a=10
Combine 5a and −3a to get 2a.
2a−20=10
Add 20 to both sides.
2a=10+20
Add 10 and 20 to get 30.
2a=30
Divide both sides by 2.
a=230
Divide 30 by 2 to get 15.
a=15

Write 4 2/5 as an improper fraction
22/5
Explanation-
First, multiply 4x5, Then you get the product 20. With that 20, add with 2, so, 20+2=22. Now, place denominator as it is, then write 22 as numerator. So you get the answer as 22/5.
Working-
4×5=20
→ 20+2=22
→ 22
→ 22/5
Write a word problem that could be solved by the equation in problem 8 .
3 1/2 [tex]3 1/2 divided by 7/8= 7/2*8/7= 56/14 =4[/tex]
The word problem is " In a class there are 8 boys and these are 2/3rd parts of total students. How many students are there".
The given expression is 8÷2/3
We need write a word problem which is solved by the above expression.
Word problem : In a class there are 8 boys and these are 2/3rd parts of total students. How many students are there.
Solution
[tex]x[/tex]* × 2/3 =8
Divide both sides by 2/3.
x=8/2/3
x= 8×3 / 2
x= 12
Therefore, the total number of students is 12.
