Answers
Step-by-step explanation:
-3x + 7y = 5x + 2y (you subtract the 2y from both sides)
-3× + 5y = 5x (then add 3x to both sides)
5y = 8x (use x = - 5)
5y = 8x - 5 = -40 (both sides are divided by 5)
y = -8
answer is (-5, -8)

write number 5 million 4 thousand 3 hundread in standard form
Answers
5 million, four thousand, three hundred in standard form is 5.0043 x 10^6
Solution:
Need to represent 5 million, four thousand, three hundered in standard form
5 million = 5000000
4 thousand = 4000
3 hundred = 300
5 million, four thousand, three hundred = 5000000 + 4000 + 300 = 5004300
In standard form, decimal comes after first digit and multiply to power of 10 dependency on total digits of number.
In our case, given number is 5004300.
So we need decimal after first and after that multiplying it by appropriate power of 10. So,
5004300 = 5.0043 x 10^6
Hence 5.0043 x 10^6 is standard form of 5004300 that is standard form of 5 million, four thousand, three hundred.

A prediction based on the data is not completely reliable, because the means are too close together. D. A prediction based on the data is reliable, because the means of the samples are close together.
Answers
Answer:
A
Step-by-step explanation:
The statement which is most accurate based on the data is option(D)A prediction based on the data is reliable, because the means of the samples are close together.
What is Mean?Mean is the average of the given numbers and is calculated by dividing the sum of given numbers by the total number of numbers
From the given data,
Mean of the sample 1 = 15.9
Mean of the sample 2 = 15.7
Mean of the sample 3 = 15.6
All three mean are close together.
Therefore the data is reliable
Hence, the statement which is most accurate based on the data is option(D)A prediction based on the data is reliable, because the means of the samples are close together.

Find the percent of change.
Answers
Answer: Percent change = 20%
===========================================================
Work Shown:
A = old value = 25 (last week's number)
B = new value = 30 (current week's number)
C = percent change
C = [ (B-A)/A ] * 100%
C = [ (30-25)/25 ] * 100%
C = [ 5/25 ] * 100%
C = 0.20* 100%
C = 20%
The percent change is 20%
The positive value of C indicates we have a percent increase.

At the coordinate of -9, the value of the function g(-9) will be 1.
What is coordinate geometry?A coordinate plane is a 2D plane that is formed by the intersection of two perpendicular lines known as the x-axis and y-axis. A coordinate system in geometry is a method for determining the positions of the points by using one or more numbers or coordinates.
Given that in the graph the function is varies with the value of the coordinates, at the value of -9 the solution for the function g(-9) will be equal to 1
g(-9) = 1
Hence, the value of the function will be 1.

Quiana has 7 times more text messages from Yolanda than from Pierre. Quiana has 42 text messages from Yolanda. Which equation can be used to find how many text messages Quiana has from Pierre, p?
Answers
Quiana has 8 text messages from Pierre.
Step-by-step explanation:
This question can be solved using a rule of three.
Quiana has 7 times more text messages from Yolanda than from Pierre.
This means that for each message that she receives from Pierre, she receives 7 from Yolanda.
She received 56 from Yolanda.
So
7 messages from Yolanda - 1 messages from Pierre
56 messages from Yolanda - x messages from Pierre
Quiana has 8 text messages from Pierre

I will make brainlist
Answers
Answer:
16 ft
Step-by-step explanation:
We start by converting 1yd to ft,
1yd = 3ft
So in the smaller triangle, we have 3ft, 4.5ft. Using Sine, Cos, and Tan rule. We know that
TanΦ = opposite / adjacent
TanΦ = 3ft / 4.5ft
TanΦ = 0.667
Φ = Tan^-1 0.6
Φ = 33.69
This means that the angle of elevation is 33.69°
Using this angle, and the same tan rule again, we gave
Tan 33.69 = opp/24
0.667 = opp/24
opp = 24 * 0.667
opp = 16 ft
