Answer:
21 + 3t
Step-by-step explanation:
Use distributive property: a*(b +c) =(a*b) + (a*c)
8(2 +t) - 5(t - 1) = 2*8 + t *8 + t *(-5) - 1*(-5)
= 16 + 8t -5t + 5
= 16 + 5 + 8t - 5t {Combine like terms}
= 21 + 3t

Which statements are true about the ordered pair (10, 5) and the system of equations?
{ 2x−5y=−5
{ x+2y=11
Select each correct answer.
The ordered pair (10, 5) is a solution to the first equation because it makes the first equation true.
The ordered pair (10, 5) is a solution to the second equation because it makes the second equation true.
The ordered pair (10, 5) is not a solution to the system because it makes at least one of the equations false.
The ordered pair (10, 5) is a solution to the system because it makes both equations true.
Answer:
the solution to the system is (5,3)
Step-by-step explanation:
the first statement is True: 2(10) - 5(5) = -5
20 - 25 = -5
-5 = -5
the second statement if False: 10 + 2(5) ≠ 11
the third statement is True
the last statement is False

So.... using the point-slope formula
y-y₁=m(x-x₁)
y₁ is the y-coordinate
x₁ is x-coordinate
m is the slope
when we find the slope from both points we find that they both have a slope of 16/3
therefore... the lines are parallel

1. John Smith has a past due balance of $80 on his account. He called today to pay off his balance in full. You receive 25% commission of his payment to go toward your budget. What is your total commission received from John's payment?
Answer: $20
Step-by-step explanation:
From the question, we are informed that John Smith has a past due balance of $80 on his account and out of the $80 paid, 25% will be given as commission.
Therefore, the total commission received from John's payment will be:
= 25% × $80
= 25/100 × $80
= 0.25 × $80
= $20
The commission is $20

I NEED HELP ,PLAESE AYUDAAAAA POR FAVOR
Answer:
Step-by-step explanation:
First off, if side BC and side EC are congruent, then this is an isosceles triangle. It then goes to follow by the Isosceles Triangle Theorem that angle EBC is also 67 degrees. By the Triangle Angle-Sum Theorem then, angle BCE is 180 - 67 - 67 which is 46 degrees. Angle BCE is supplementary to angle FCA which means they add up to equal 180, so angle FCA is 180 - 46 = 134.
Angle FCA = 134
Olivia is making model cars to go on shelves in her room. The number of wheels she uses is a function of how many cars she makes: if she makes 1 car, she uses 4 wheels; if she makes 2 cars, she uses 8 wheels; if she makes 3 cars, she uses 12 wheels; and so on. She has exactly 28 wheels she can use to make cars. What is the domain and range for the function?
Answer:
Domain = 1 to 7
Range = 4 to 28
Step-by-step explanation:
Given that:
Number of wheels used is a function of number of cars manufactured.
Number of wheels present = 28
1 car uses 4 wheels
2 cars use 8 wheels.
3 car uses 12 wheels
and so on.
Let the function be of the form:
[tex]y =f(x)[/tex]
Domain of the function is the value of [tex]x[/tex] that can be given as valid input to the function.
Range of the function is the value of [tex]y[/tex] that can be output of the function.
Let [tex]x[/tex] be the number of cars manufactured.
Then value of [tex]y[/tex] is nothing but [tex]x[/tex] times 4.
[tex]y=4x[/tex]
We are given that maximum value of [tex]y[/tex] can be 28.
[tex]28 = 4x\\\Rightarrow x =7[/tex]
Therefore, maximum value of input can be 7.
Minimum number of wheels can be 4 to make a minimum of 1 car.
Therefore domain is 4 to 28 and range is 1 to 7.
In figure below alb, m<1 = 78°, and m<2 = 47°.
Find measure of each angle.
Answer:
m∠3 = 102°
m∠4 = 102°
m∠5 = 78°
m∠6 = 133°
m∠7 = 47°
m∠8 = 47°
m∠9 = 133°
m∠10 = 102°
Step-by-step explanation:
Lines a and b are parallel and
m∠1 = 78° and
m∠2 = 47°
m∠3 = 180 - m∠1 = 180 - 78 = 102°
m∠4 = m∠3 = 102°
m∠5 = m∠1 = 78°
m∠6 = 180 - m∠7 = 180 - m∠2 = 133°
m∠7 = m∠2 = 47°
m∠8 = m∠2 = 47°
m∠9 = 180 - m∠8 = 180 - 47 = 133°
m∠10 = 180 - m∠1 = 102°

, Natasha worked 7 hours at a diner for $10 per hour last week. She also makes $8 per hour when she babysits. She wants $206 for a prom dress. Create an inequality to show how many hours she must babysit.
Answer: x ≥ 17
Step-by-step explanation:
We know that she worked 7 hours at a dinner, for $10 per hour last week.
Then in the last week, she did make:
7*$10 = $70
Now she babysits, she wins $8 per hour, then if she works x hours, she will win:
w(x) = $8*x
if we add the $70 that she already had, we have:
$70 + $8*x
And we know that she wants to have, at least, $206, then we can write the inequality.
$70 + $8*x ≥ $206.
Now let's solve this for x.
first, we can subtract $70 in both sides:
($70 + $8*x) - $70 ≥ $206 - $70
$8*x ≥ $136
now we can divide by $8 in both sides:
($8*x)/$8 ≥ $136/$8
x ≥ 17
This means that she must babysit for at least 17 hours if she wants to buy the dress.
