Answer: (4, 3)
Step-by-step explanation:
Let's use substitution.
So for y in the first equation we will substitute the expression for y in the second.
2x - 3(x-1) = -1
2x -3x + 3 = -1
-1x + 3 = -1
-3 -3
-1x = -4
-1x / -1 = -4 / -1
x = 4
Now plug in x for the second equation
y = 4 - 1
y = 3
Now check it using the first equation:
2(4) - 3(3) = -1
8 - 9 = -1
-1 = -1
It's true so it's correct

HELP PLEASE I NEED TO KNOW IF IM GOING TO BE HELD BACK!!!
What grade point average would I have if I had 3 A's, 1 B, 1 D, and 1 F.
Answer:
You are doing good I would say! Your average grade would be a B- Or just a normal B Somewhat around there.
Step-by-step explanation:
I hope this helps you and good luck! Bye!
Grade scale:
A → 100-90
B → 89-80
C → 79-70
D → 70
F <70
That being said to see your grade, add all your grades up then divide it by how many grades you have.
That being said, if you add all your grades then divide it by how many grades you have, you should have a 85.6 as your average.
Hence, your average is a B.

A civil engineer tested concrete samples to investigate the difference in strength, in newtons per square millimeter (N/mm2), between concrete hardened for 21 days and concrete hardened for 28 days. The engineer measured the strength from each sample, calculated the difference in the mean strength between the samples, and then constructed the 95 percent confidence interval, (2.9,3.1), for the difference in mean strengths.

M<1=115
M<2
Could y’all give answers for all though
Answer:
1) m<2 = 115°
2) m<5 = 83°
3) m<8 = 45°
4) m<4 = 137°
Step-by-step explanation:
When two lines cross over each other, creating four angles, the opposite angles are equal.
So in question one, <1 is equal to <2, the angle opposite it, and so it is 115°.
Similarly, in question two, <5 = <6 = 84°.
In question three, <8 = <9 = 45°.
and in question four, <3 = <4 =137°.
Answer:
1) 115
2) 83
3) 45
4) 137
Step-by-step explanation:
Each problem is asking you to find the missing angle given its vertical angle.
Vertical angles are congruent therefore the angle given is the answer
Just in case that doesn't make sense here you go:
For #1 ∠1 and ∠2 are vertical angles
vertical angles are congruent ( equal to each other ) so if
∠1 = 115° then ∠2 = 115°
For#2 ∠5 and ∠6 are also vertical angles so they are congruent
so if ∠5 = 83° then ∠6 = 83°
For #3 ∠8 and ∠9 are vertical angles so they are congruent
so if ∠8 = 45° then ∠9 = 45°
For #4 ∠3 and ∠4 are vertical angles so they are congruent
So if ∠3 = 137° then ∠4 = 137°

If you deposit $300 a month into an account that accredits you 3% compounded monthly, how much money will you have in your account after 25 years?
A. $112,430
B. $133,800
C. $122,653
D. $98,902
Compound interest is the interest generated on a sum of money invested. The amount of money that you will have in your account after 25 years is $122,653
How to calculate the compound interest?Compound interest is the interest generated on a sum of money invested. The formula for calculating compound interest is expressed as:
A = P(1+r/n)^nt
Given the following parameters
Principal P = $3600 (a year)
rate r = 0.03
Time t = 25 years
n = 12 (time of compounding)
Substitute
A = 3600(1 + 0.03/12)^12(25)
A = 3600 (1.0025)^300
A = 3600(2.1150)
A = $122,653
Hence the amount of money that you will have in your account after 25 years is $122,653

Find angle B. What is angle B.
Answer:
B=45 Degrees
Step-by-step explanation:
You can use law of sines to answer. Law of Sines states that [tex]\frac{sin(a)}{A} =\frac{sin(b)}{B}[/tex]. That means that [tex]\frac{sin(60)}{4\sqrt{6} }=\frac{sin(b)}{8}[/tex]. Multiplying 8 to both sides gives us [tex]\frac{8sin(60)}{4\sqrt{6} }=sin(b)[/tex]. By using inverse of sin, we get [tex]b = sin^{-1} (\frac{8sin(60)}{4\sqrt{6} } )[/tex]. Plugging that into a calculator gives us b=45 degrees.

Repent while there’s still time. Love while you still can. Give till there’s nothing left. Serve with all you’ve got. Go while you’re still able. Share all that you have. Follow hard after God. Live with no regrets. Time is of the essence. If we only have today, there’s still time. Don’t miss this time. Look yourself in the mirror and ask your self - If I died today, would the Lord judge me worthy of eternal life? If the answer is no, then ask him for forgivness. As long as you are really sorry, he will forgive you. If you want to talk, I am here. If you need time alone, then I will leave you alone. If you need a Bible, I can get you one. Follow your heart and never stop doing good. Thank you for reading this, and have a great day. May the good Lord bless you, your family, and the world.

The language arts teacher wants to know whether the students in the entire school prefer a debate or an speech. The teacher draws a random sample from the following groups: All teachers in the school All boys in each grade All students in the speech club All students in each grade Which group best represents the population she should take a random sample from to get the best results for her survey? (5 points) a All teachers in the school b All boys in each grade c All students in the speech club d All students in each grade
Answer:
D, all the students in each grade
Step-by-step explanation:
Since the teacher wants to find out the opinion of the the entire school, they should take a random sample from each grade because it is representative of the population they want to sample. If it was just boys, it would exclude the girls, and vice versa for the girls. The teachers aren’t part of the population the teacher wants to survey, so the teacher shouldn’t survey them. Thus, that leaves the random sample from each grade.

QUESTION:

ANSWER:
Okay, so everyone knows that a straight angle/ full triangle equals up to the sum of 180°, right?
So you take the 180° and subtract the 51°. And you should be getting 129°.
But, since this is a right triangle all I did was subtract 51° from 90° (a right triangle). In the end, the final answer is 39°
