Answer:
[tex]x=3[/tex]
Step-by-step explanation:
The first step is to isolate the variable on one side. In this case, let's try to bring x to the right. We do this by adding 3x to both sides, which gives us:
[tex]7 = 2x + 1[/tex]
Now, to have just the x term on the right, we subtract one from both sides of the equation, giving:
[tex]6 = 2x[/tex]
The last step is to divide both sides by two to leave x by itself. Thus, after dividing, we get:
[tex]3 = x[/tex]

A scatterplot has a positive, linear correlation. Which statement is true about the relationship between the x- and y-
values?
o As the x-values increase, the y-values tend to increase.
As the x-values increase, the y-values tend to decrease.
As the x-values decrease, the y-values tend to increase.
O As the x-values decrease, the y-values tend to vary randomly.
Answer:
Hence, option: A is the correct answer.
A. As the x-values increase, the y-values tend to increase.
Step-by-step explanation:
It is given that:
A scatterplot has a positive, linear correlation.
By positive we means that as the x-value increases the y-value also keeps on increasing and by linear relation we mean that it increases somewhat by a constant amount so that the we get a line of best fit.
Hence, the statement which is true about the relationship between the x- and y-values is:
A. As the x-values increase, the y-values tend to increase.
Answer:
a: As the x-values increase, the y-values tend to increase.

A cup contains seven red erasers, four
yellow erasers, nine blue erasers, and five
green erasers. Samantha chose an eraser
at random, did not replace it, and chose
another. What is the probability that both
erasers chosen were blue?
Answer:
17/50
Plzzzz give me Brainliest!
The probability that both erasers chosen were blue is 3/25.
To find the probability that both erasers chosen were blue, we need to determine the favorable outcomes (choosing two blue erasers) and the total possible outcomes.
There are a total of 25 erasers in the cup: 7 red erasers + 4 yellow erasers + 9 blue erasers + 5 green erasers = 25 erasers.
To calculate the probability, we consider the events of choosing a blue eraser without replacement.
For the first pick, there are 9 blue erasers out of 25 total erasers.
After the first blue eraser is chosen, there are 8 blue erasers remaining out of 24 total erasers.
The probability of choosing a blue eraser on the first pick is 9/25.
The probability of choosing a blue eraser on the second pick, without replacement, is 8/24.
To find the probability of both events occurring (both erasers chosen being blue), we multiply the probabilities together:
(9/25) * (8/24) = 72/600 = 6/50 = 3/25
Therefore, the probability that both erasers chosen were blue is 3/25.

Answer:
15x^2-14x-4
Step-by-step explanation:
(8x^2 * x-7x+2)+(7x^2 -7x-6)
you take out the parentheses
you add the common ones so -7x+-7x= -14x
8x^2 +7x^2 = 15x^2
and 2-6= -4
so in total it's 15x^2-14x-4
Answer: 11x^2 -16x-3
Step-by-step explanation:
Solution:
Your problem → (8x^2-7x+2) + (3x^2-9x-5)
(8x2-7x+2)+(3x2-9x-5)
=8x2-7x+2+3x2-9x-5
=8x2+3x2-7x-9x+2-5
=11x2-16x-3

Solve for h.
h/10 + 5 = 25
so what’s h ??
Answer:
h=200
Step-by-step explanation:
h/10+5=25
h/10=20
h=200
h/10 + 5 = 25
Subtract 5 from each side to get h/10 alone.
h/10 + 5 - 5 = 25 - 5
h/10 = 20
Multiply both sides by 10 to get h alone.
h/10 • 10 = 20 • 10
h = 200
h = 200. I hope this helps!
