Answer:
y = - 3x + 7
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = - 3, then
y = - 3x + c ← is the partial equation
To find c substitute (3, - 2) into the partial equation
- 2 = - 9 + c ⇒ c = - 2 + 9 = 7
y = - 3x + 7 ← equation of line

In a class of 32 students
the mean height of the 14 boys is 1.56 meters.
the mean height of all 32 students is 1.515 meters.
Work out the mean height of the girls.
Please help
WINNER GETS BRAINLIEST!!!!!!
Answer:
1.48 m
Step-by-step explanation:
In a class of 32 students
the mean height of the 14 boys is 1.56 meters.
the mean height of all 32 students is 1.515 meters.
Total number of students = 32
Mean height of all students = 1.515
We can obtain the sum of all student's height :
Number if students * mean height
= 32 * 1.515
= 48.48
Number of boys = 14
Mean height of boys = 1.56m
We can obtain the sum of all boys height :
Number if students * mean height
= 14 * 1.56
= 21.84
Number of girls :
All students - Number of boys
32 - 14 = 18
Sum of girls height :
48.48 - 21.84 = 26.64
Mean height of girls :
Sum of girls height / Number of girls
26.64 / 18
= 1.48 m

Joe receives a weekly salary of $350 plus 10% commission on all sales. Last week, Joe had a total of $1,000 sales. How much total money did Joe make?
Given:
Weekly salary of Joe = $350
Commission of sales = 10%
Total sales of last week = $1,000.
To find:
The the total money did joe make.
Solution:
We have,
Commission of sales = 10%
Total sales of last week = $1,000
[tex]\text{Commission}=10\%\text{ of }1000[/tex]
[tex]\text{Commission}=\dfrac{10}{100}\text{ of }1000[/tex]
[tex]\text{Commission}=100[/tex]
Now,
Total weekly income = Weekly fixed salary + Commission
[tex]=350+100[/tex]
[tex]=450[/tex]
Therefore, the total income of Joe for last week is $450.

solve this system of equations.
3x+4y=4
-x-3y=7
Answer:
x = 8, y = -5
Step-by-step explanation:
Multiplying the 2nd equation by 3, we get -3x-9y = 21. Then eliminating with the first equation we get -5y = 25. y = -5. Substituting this into the original equation, we get x = 8.
Answer:
x=8 y=-5
Step-by-step explanation:
3x+4y=4 3x+4y=4
3(-x-3y=7)= -3x-9y=21
-3x-9y=21 -5y=25
y=-5
3x+4(-5)=4
3x-20=4
3x=24
x=8

how do I determine if a function is even, odd, or neither
Answer:
The way to do is dow below
Step-by-step explanation:
You may be asked to "determine algebraically" whether a function is even or odd. To do this, you take the function and plug –x in for x, and then simplify. If you end up with the exact same function that you started with (that is, if f (–x) = f (x), so all of the signs are the same), then the function is even.

Janice makes $5.25 per hour babysitting. In one week she received a bonus of $25 plus her hourly rate. Which equation would express Janice’s earnings if she wants to get more than $250 for the week?
A. $5.25h – 25 > $250
B. $5.25 + h + 25 > $250
C. $5.25h + 25 > $250
D. $5.25 – 25h > $250
Answer: C
Step-by-step explanation: The $25 is added on to the constant rate of $5.25. This means that it would be $5.25 + $25 > $250
Answer:
C
Step-by-step explanation:
$5.25 is affected by the number of hours she baby sits, so it needs to have an h next to it to show that, that makes B and D incorrect.
You need to add 25 to the total, not subtract it, so A is also incorrect. that leaves C
