yuson must complete 30 hours of community service. she does 2 hours each day. which linear equation represents the hours yuson has left after x days?
Answer:
30-2x
Step-by-step explanation:
yuson has to finish am total of 30 hours in community service
she does 2 hours each day
in x days, hour of service done=2x
after x days hours of service left=30-2x
therefore the linear equation representing the hours yuson has left after x days is:
30-2x

I’m very confused and don’t understand anything that’s going on please help
Answer: 112, 68, 22, 90
Step-by-step explanation:
This is fairly somewhat easy
since the adjacent side of 1 is 68 degrees
then 1 would be 112 degrees to make it supplementary to 180 degrees
angle 3 is vertical of angle 68
making it 68 degrees
angle 5 is given to be 90 degrees meaning angle 4 is inbetween
angles 3 and 5 so ( 68 and 90 ) that'll add up to 158 meaning angle 4
is 22
angle 1 = 112
angle 3 = 68
angle 4 = 22
angle 5 = 90

3x+y=-9
Y=5x+7
Solve the system of linear equations by substitution
Answer:
x=-2
Step-by-step explanation:
Substitute y=5x+7 into the equation 3x+y=-9
So you will have, 3x+5x+7=-9
3x+5x=8x
8x+7=-9
8x+7-7=-9-7
8x=-16

Answer:
7.) m = 1/3 ; b = -2.5
8.) m = 2 ; b = 2
Step-by-step explanation:
For m, either do the rise over run method or use 2 points and do (y2-y1)/(x2-x1).
For b, just look at the y-intercept/where it crosses the y axis

For the line above, what is the slope? *
Answer:
1
Step-by-step explanation:
Find the rise over run
Rise = 3
Run = 3
3/3 = 1
Slope = 1
Answer:
1
Step-by-step explanation:
First, you take any two points from the line, I put (2,1) and (0,-1). You plug it into the formula y2-y1/x2-x1 which would be -1-1/0-2 which is equal to -2/-2=1

Find the y intercept of the following line (-2,1) and (1, 2.5)
Answer:
2
Step-by-step explanation:
(-2 , 1) ; (1, 2.5)
Slope = [tex]\frac{y_{2}-y_{1}}{x_{2}-x_{1}}\\[/tex]
[tex]\frac{2.5-1}{1-[-2]}\\\\= \frac{1.5}{1+2}\\\\=\frac{1.5}{3}\\\\= 0.5[/tex]
m =0.5
y -y1 =m(x -x1)
y - 1 = 0.5(x - [-2])
y - 1 = 0.5(x + 2)
y -1 = 0.5x + 0.5*2
y - 1 =0.5x + 1
y = 0.5x + 1 + 1
y = 0.5x + 2
y-intercept = 2

13x = 3(X-20) How to solve this algebra equation?
Answer:
x = -6
Step-by-step explanation:
13x = 3(x - 20) {Use distributive method:a(b+c)=(a*b) + (a*c)
13x = 3*x - 3*20
13x = 3x - 60 {Subtract '3x' from both sides}
13x -3x = -60
10x = -60 {Divide both sides by 10}
x= -60/10
x = -6

Albert O'Malley signs a promissory note for $3,500 for 150 days at 9% exact interest. Find the interest he must pay _____ and the total amount due on the due date _____.
Answer:
He must pay $129.45 and the total amount due is $3,629.45.
Step-by-step explanation:
I (interest) =P (principal) x R (rate) x T (time)
I=3500x.09x150/365
I=129.45
A (amount due) = P (principal) + I (interest)
A= 3500 + 129.45
A= $3629.45

Evaluate the expression 6 + 4 x {3+7}.
Answer:
46
Step-by-step explanation:
6 + 4 x {3+7} [B.O.D.M.A.S rule] (First bracket)
= 6 + 4 × 10. (Then Multiplication)
= 6 + 40. ( At last addition)
= 46 (Ans)
The simplified value of the expression 6 + 4 × {3 + 7} is 100.
What is PEMDAS rule?PEMDAS rule states the correct order of simplifying an expression is as follows -: Parenthesis, exponents, multiplications, divisions, additions, and, subtractions.
Given, An expression 6 + 4 × {3 + 7}.
First, we'll add 6 and 4 as 3 and 7 are inside curly brackets,
not in parentheses.
Therefore,
6 + 4 × {3 + 7}.
= 10 × {3 + 7}.
Now, we can either distribute the terms or take the addition and multiply.
= 10 × 10.
= 100.
