Answer:
154
Step-by-step explanation:
The n th term of an arithmetic sequence is
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 7 and d = 10 - 7 = 3 , thus
a₅₀ = 7 + (49 × 3) = 7 + 147 = 154

The function g(m) gives output n to satisfy equation:
-2m - 5n = 7m - 3nSolving this equation for n:
-2m - 5n = 7m - 3n-2m - 7m = -3n + 5n-9m = 2n2n = -9mn = -9/2mn = - 4.5mSo the function is:

Mark gather data about the number of pink and red flowers that bloom down several of his flowering shrubs the scatterplot shows did he gathered and line of best fit equation of the line of best fit is y=1.73x + 0.0924 Based on the line of best fit approximately how many pink flowers are predicted to bloom on a shrub with 40 red flowers
Answer:
im pretty sure its 69 cause if u look its halfway between 33 and 33x2 is 66 and 69 is ther closest to that
Step-by-step explanation:
From the line of best fit, the pink flowers that would bloom on a shrub with 40 flowers = 69.29
How to solve for the pink flowers using the line of best fit.
The equation of the regression line = y=1.73x + 0.0924
We have x = 40
We have to put the value of x in the equation
y=1.73*40 + 0.0924
= 69.29
Therefore the line of best fit that would bloom on a shrub with 40 red flowers is 69.29

Lindsey's cookie recipe uses 1 1/2 cups of brown sugar to make 2 dozen cookies. Lexi wants to make only 1 dozen cookies. How much brown sugar should Lexi use?
Answer:
(3/4) cups
Step-by-step explanation:
It is given that,
Lindsey's cookie recipe uses 1 1/2 cups of brown sugar to make 2 dozen cookies.
We need to find how much brown sugar should Lexi use to make only 1 dozen cookies.
2 dozen cookies = 1 1/2 cups
= 3/2 cups
For 1 dozen cookies,
[tex]\dfrac{\dfrac{3}{2}}{2}\\\\=\dfrac{3}{4}\ \text{cups}[/tex]
So, to make 1 dozen cookies, she will need (3/4) cups of brown sugar

A family is taking a car for a road trip. The distance traveled is represented by y=55x. The distance in miles y and gallons used by the car is x.
Part 1. If the car has gone 385 miles, how much gas was used?
Part 2. The inverse function for this situation is the gallons of gas as a function of distance in miles. Write this equation.
Answer:
y=55x
given y=385
x=gallons of gas = 385/55 = 7 gallons
inverse function
y=55x
change x to y and y to x
x=55y
y=x/55
inverse function is x/55

Daisy purchases a gym membership. She pays a signup fee and a monthly fee of $13. After 4 months, she
has paid a total of $79. Use a linear equation in point-slope form to find the signup fee. Solve the problem
using an equation in point-slope form.
The signup fee is__
PLS HELP
Answer:
$6.75
Step-by-step explanation:
First, we need to figure out how much she pays in a month: 79 divided by 4 = 19.75
But, this includes the sign up fee because the problem states, " After 4 months, she has paid a total of $79. "
Now, we need to subtract the first fee (13) " She pays a signup fee and a monthly fee of $13. "
19.75 - 13.00 = 6.75

Answer:
y - 3 = (1/2)(x - 4)
Step-by-step explanation:
The graph is hard to read, but we can make assumptions about the x- and y-values shown. The y-intercept appears to be (0, 1) and the blue dot appears to be (4, 3). Let's try finding the equation of the line using this assumed data:
The point-slope equation is y - k = m(x - h), where (h, k) is a point on the line and m is the slope of the line.
We need the slope of the line. Recall that m = rise/run. Going from (0, 1) to (4, 3), x (the 'run') increases by 4 and y (the 'rise') increases by 2. Thus, the slope is m = rise/run = 2/4, or 1/2.
Substituting the known values into the point-slope equation y - k = m(x - h), we get:
y - 3 = (1/2)(x - 4)

13 of the 18 players on the varsity soccer team are seniors. What percent of the players on the team are not seniors?
Answer:
27.7778
Step-by-step explanation:
If 13 out of 18 players are seniors then 5 of them are not.
To find the percentage you do (5/18) ⋅ 100
5 divided by 18 gives us 0.27777778
Then we multiply by 100 (or move the decimal point two spaces to the right)
The result should be 27.7778%
(the 7s go on forever)
Can you pleasee explain how to find a y- intersept??
a y-intercept is any point that has an x-value of 0. for example, the ordered pairs (0,6) and (0,-4) would both be considered y-intercepts since any point with an x-value of 0 overlaps with the y-axis.
Answer: to find a y intercept you have to use the slope intercept form y = mx+b the m is the slope and the b is the y intercept the intercept depends on the value where y crosses the y axis.

Solve for y.
Answer:
[tex]y = \frac{1094-3x}{47}[/tex]
General Formulas and Concepts:
Order of Operations: BPEMDASEquality PropertiesStep-by-step explanation:
Step 1: Define equation
3x + 47y = 1094
Step 2: Solve for y
Subtract 3x on both sides: 47y = 1094 - 3xDivide both sides by 47: y = (1094 - 3x)/47
