Answer:
The first step is to find a number that when subtracted from 2 gives you 2.
Step-by-step explanation:
The algebraic part of this problem would be to add the -2 (adding 2 to both sides) to both sides, so
first x-2=2, then x-2(+2)=2(+2) which would give us,
x=4
*note: the parenthesis are just to show that we are adding the 2, to make it more understandable.

One year Terry had the lowest ERA (earned-run average, mean number of runs yielded per nine innings pitched) of any male pitcher at his school, with an ERA of 2.85 . Also, Karla had the lowest ERA of any female pitcher at the school with an ERA of 2.95 . For the males, the mean ERA was 4.893 and the standard deviation was 0.949 . For the females, the mean ERA was 4.348 and the standard deviation was 0.997 . Find their respective z-scores. Which player had the better year relative to their peers, Terry or Karla ? (Note: In general, the lower the ERA, the better the pitcher.)
Answer:
Their respective z-scores are:
Thomas : -2.15279
Karla : -1.40221
Which player had the better year relative to their peers, Terry or Karla ?
Terry had a better year because he had a lower Era and he was a better pitcher.
Step-by-step explanation:
The formula for calculating a z-score is is z = (x-μ)/σ,
where x is the raw score,
μ is the population mean
σ is the population standard deviation.
any male pitcher at his school,
For Thomas:
z = (x-μ)/σ
x = 2.85 μ = 4.893 σ = 0.949.
z = 2.85 - 4.893/0.949
z = -2.15279
For Karla
z = (x-μ)/σ
x = 2.95 μ = 4.348 σ = 0.997.
z = (2.95 - 4.348) /0
z = -1.40221
Their respective z-scores are:
Thomas : -2.15279
Karla : -1.40221
Which player had the better year relative to their peers, Terry or Karla ? (Note: In general, the lower the ERA, the better the pitcher.)
Terry had a better year because he had a lower Era and he was a better pitcher.

Given two points on a line, explain how you can use point-slope
form to write an equation of the line.
To find the point slope of a line you must first know the slope of the two points. You would substitute the points into the slope formula y2-y1/x2-x1.
Then you would put the slope into the point slope formula:
y-y1=m(x-x1)
"m" is the slope of the formula.

in a complete sentence describe how much smaller the 3 in 743,857 is than the 3 in 735,957
Answer:
The 3 in 743,857 is 27,000 less than the 3 in 735,957.
Step-by-step explanation:
in 743,857 the 3 is 3,000
in 735,957 the 3 is 30,000
30,000 - 3,000 = 27,000

rewrite the linear equation 2x=1/3y-9 in slope- intercept form.
y=. x. +
Answer:
y = 6x + 27
Step-by-step explanation:
The required linear equation would be y = 6x + 27 in the slope-intercept form.
What is a Linear Function?A linear function is defined as a function in the form of f(x) = mx + c where 'm' and 'c' are real numbers.
It represents the line's slope-intercept form, which is written as y = mx+ c.
Linear equations can be solved in four different ways: by adding, subtracting, multiplying, and dividing.
The linear equation is given in the question
⇒ 2x = (1/3)y - 9
We have to rewrite the equation in the slope-intercept form.
⇒ 2x = (1/3)y - 9
Multiply by 3 both sides of the above equation,
⇒ 6x = y - 27
Rearrange the term of y to get
⇒ y = 6x + 27
Therefore, the required linear equation would be y = 6x + 27 in the slope-intercept form.

A circle is translated 4 units to the right and then reflected over the x-axis. Complete the statement so that it will always be true of the circle at the new location.
The circle at the new location has the original circle.
the same center as
twice the circumference of
half the radius of
the same area as
Options
The circle at the new location has _____________ the original circle.
- the same center as
- twice the circumference of
- half the radius of
- the same area as
Answer:
the same area as
Step-by-step explanation:
When a circle is translated and reflected, the center of the circle will change; however, its area, circumference, radius and diameter remain the same.
This is so because, translation and reflection only affect the positioning of the circle not the size.
Considering the above analysis, we can conclude that option d answers the question correctly.
Answer:

Anyone know how to do??
Answer:
x = 15°
Step-by-step explanation:
∠2 and ∠4 are same-side interior angles, meaning they add up to 180
2x + 10 + 4x + 80 = 180
Rearrange (collect like terms)
6x = 180 - 80 - 10
6x = 90
x = 15°
Answer:
x = 15Step-by-step explanation:
∠2 = 2x + 10
∠4 = 4x + 80
∠2 and ∠4 are supplementary angles, this mean ∠2 + ∠4 = 180
2x + 10 + 4x + 80 = 180
combine similar terms: 6x = 180 - 80 - 10
simplify: 6x = 90
solve for x = 90 / 6
x = 15

how p(x) differs from g(x)
p(x)=8x^2
g(x) = x^2
Answer:
Step-by-step explanation:
p(x) = 8x^2 is an increasing exponential curbed graph which starts from quadrant 2 , passes through the point (0, 8) on the y axis and rises steeply to the right.
g(x) = x^2 is a parabola ( shaped like a U) which has a minimum value at (0, 0).
and opens upwards either side of the y-axis. This type of curve is called a parabola.

What are the first 4 terms use the explicit rule:
f(n)= 3n-1
(show your work)
Answer:
25811Step-by-step explanation:
We are given the rule [ f(n) = 3n - 1 ] and n represents the term.
First term:
f(n) = 3n - 1
f(1) = 3(1) - 1
f(1) = 3 - 1
f(-1) = 2
Second term:
f(n) = 3n - 1
f(2) = 3(2) - 1
f(2) = 6 - 1
f(2) = 5
Third term:
f(n) = 3n - 1
f(3) = 3(3) - 1
f(3) = 9 - 1
f(3) = 8
Fourth term:
f(n) = 3n - 1
f(4) = 3(4) - 1
f(4) = 12 - 1
f(4) = 11
As you can see, the common difference is 3.
