Step-by-step explanation:
Given the following equations, at which point will the graphs intersect?
f(x) = 5x + 1
g(x) = -2x + 15
(0,0) (1,15) (-2,-9) (2,11)
Answer:
(2,11)
Step-by-step explanation:
f(x) = 5*2 + 1 = 11
g(x) = -2 *2 + 15 = 11
what is the missing variable
Answer: x= 18
Step-by-step explanation: these are corresponding angles which means they are equal.
(4x-7) = (7x-61)
-7 = 3x -61
54 = 3x
18 = x
Use the regression calculator to compare the teams’ number of runs with their number of wins.
A 2-column table with 9 rows. Column 1 is labeled R with entries 808, 768, 655, 684, 637, 619, 613, 609, 563. Column 2 is labeled W with entries 93, 94, 66, 81, 86, 75, 61, 69, 55.
What is the y-intercept of the trend line, to the nearest hundredth?
Answer:
-23.21
there should be a two part for this and the answer would be D y= 0.15x - 23.21
Step-by-step explanation:
The line of best will be y = 0.15x - 23.21 and the y-intercept is -23.21 after applying the formula.
What is the line of best fit?A mathematical notion called the line of the best fit connects points spread throughout a graph. It's a type of linear regression that uses scatter data to figure out the best way to define the dots' relationship.
[tex]\rm m = \dfrac{n\sum xy-\sum x \sum y}{n\sum x^2 - (\sum x)^2} \\\\\\\\\\rm c = \dfrac{\sum y -m \sum x}{n}[/tex]
The data is given:
R(x) W(y)
808 93
768 94
655 66
684 81
637 86
619 75
613 61
609 69
563 55
The line of best fit can be written as:
y = mx + c
Here m is the slope of the line best fit and c is the y-intercept
Putting the values in the formula we get:
m = 0.15
c = -23.21
The line of best fit is:
y = 0.15x - 23.21
Thus, the line of best will be y = 0.15x - 23.21 and the y-intercept is -23.21 after applying the formula.

On the first day of ticket sales the school sold 8 senior citizen tickets and 1 child ticket for a total of $97. The school took in $102 on the second day by selling 6 senior citizen tickets and 4 child tickets. Find the price of a senior citizen ticket and the price of a child ticket.
Answer:
A senior citizen ticket costs $11, and a child ticket costs $9.
Step-by-step explanation:
Let s = price of 1 senior citizen ticket, and let c = price of 1 child ticket.
First day:
8s + c = 97
Second day:
6s + 4c = 102
We have a system of 2 equations in 2 unknowns.
8s + c = 97
6s + 4c = 102
We will use the addition method to solve the system.
Multiply both sides of the first equation by -4. Write the second equation below it and add the equations.
-32s - 4c = -388
(+) 6s + 4c = 102
----------------------------
-26s = -286
Divide both sides by -26.
s = 11
Now substitute s with 11 in the first original equation and solve for c.
8s + c = 97
8(11) + c = 97
88 + c = 97
Subtract 88 from both sides.
c = 9
Answer: A senior citizen ticket costs $11, and a child ticket costs $9.
If you deposit $6000 into an account paying 8% annual interest compounded monthly, how much money will be in the account after 7 years?
Answer:
$10278
Step-by-step explanation:
Given data
P= $6000
R= 8%
T= 7 years
The compound interest formula is
A=P(1+r)^t
substitute
A=6000(1+0.08)^7
A=6000(1.08)^7
A=6000*1.713
A=$10278

Help me with this one
Answer:
20ft
Step-by-step explanation:
Use ratios:
[tex]\frac{5}{8} = \frac{x}{32}[/tex]
Solve for x
x = 20
Answer:
x = 20
Step-by-step explanation:
Let’s think about it this way ( i’m gonna make this as easy as possible! )
So, x is the variable, which it represents the height of the tree right? so you’re gonna want to take the shadow of the alien, and think “well can 8 make 32? and if so how many times?” which would be 8y = 32. and yes you can. so let’s think about that. how many times does it take for 8 to get to 32?
8, 16, 24, 32
so it takes 4 times. then you think “ well if 8x4 got the shadow length, 5x4 must get the tree height” which is correct.
you’ll take 5 x 4 which is 20, and you will put that down as the heigh of the tree, or think 20ft.
so x = 20.

30.5 times 15.2 times x = 6176
find x
Answer:
The answer is x = 13.32182916
Step-by-step explanation:
Isolate the variable by dividing each side by factors that don't contain the variable.
Multiply 30.5 by 15.2 .
463.6 ⋅ x = 6176
Divide each term by 463.6 and simplify.
Hoped this helped!
Brainly, please?
Answer:
13.32
Step-by-step explanation:
30.5 times 15.2 is 463.6
So now the equation is 463.6x=6176
divide both sides by 463.6
x= 13.32
N a certain year, the amount A of garbage in pounds produced after t days by an average household is given by Aequals 7.5t.
Answer:
The answer is below
Step-by-step explanation:
In a certain year, the amount A of garbage in pounds produced after t days by an average household is given by A = 7.5t.
Plot a graph for t > 0
how many days it will take to get 200 pounds of garbage.
Solution:
a) Let the time in days (t) be on the x axis and the amount of garbage (A) in pounds be on the y axis. Therefore:
At t = 0; A = 7.5(0) = 0
At t = 10; A = 7.5(10) = 75
The graph was plotted using the geogebra online graphing tool.
b) number of days require to get 200 pounds of garbage can be gotten by finding the value t for which A = 200. Therefore:
A = 7.5t
t = A / 7.5 = 200 / 7.5
t = 26.67 days

A truck is carrying 5 cars weighing a average of 4,500 pounds each. What is the total weight in tons of the cars on the truck?
Answer:
18 tons
Step-by-step explanation:
a) Given: Weight of 1 truck=4500 pounds
Thus, weight of 8 trucks= pounds
We know that 1 ton=2000 pounds
Thus, weight of 8 trucks in tons=
Hence, the total weight in tons the cars on the truck= 18 tons.
b) Given: Dimensions of the room are as
Length=10 yards and width= 168 inches
We know that 1 yard=3 feet and 1 inch=
Thus, length
width=
The difference between length and width=
Hence, the length of the room exceed the width by 16 feet.
Solve using the substitution method. 3x +2y= 19 xy= 15
Answer:
when x = 3 1/3, y = 4.5
or
when x =3 , y = 5
Step-by-step explanation:
Here, we want to solve using substitution
xy = 15
let x = 15/y
Put this into the first equation;
3(15/y) + 2y = 19
45/y + 2y = 19
Multiply through by y
45 + 2y^2 = 19y
2y^2 -19y + 45 = 0
2y^2 - 10y - 9y + 45 = 0
2y(y-5) -9(y-5) = 0
(2y-9)(y-5) = 0
2y-9 = 0
or y-5 = 0
2y = 9 or y = 5
y = 9/2 or y = 5
y = 4.5 or y = 5
Recall;
x = 15/y
x = 15/4.5 or x = 15/5
x = 3 1/3 or x = 3
