Answer:
Lin 1.454 h
Noah 1.54h
Step-by-step explanation:
From the above, we were given that;
Lin ran 2 3/4 miles in 2/5 an hour. Then, Noah ran 8 2/3 miles in 4/3 an hour
Speed of Lin
V = [(2 3/4)/(2/5)] mph
V = [(11/4)/(2/5)] mph
V = 6.875mph
Speed of Noah
V = [(8 2/3)/(4/3)] mph
V = [26/3)/(4/3))] mph
V = 6.5mph
The time taken by Lin to cover 10 miles
t = 10/6.875
t = 1.454h
The time taken by Noah to cover 10 miles
t = 10/6.5
t = 1.54h

What is the slope and y-intercept of the equation 8x +
+ 2y = 18
Show work
Please
Answer:
SLOPE = - 4
y-intercept = 9
Step-by-step explanation:
Slope = - 8/2 = - 4
Y-INTERCEPT = 18/2 = 9
PLEASE HELP ME HURRY I REALLY NEED THIS!!!! Graph the equation.
y = 2x + 4
Answer:
Step-by-step explanation:
Answer:
The slope is 2/1. The y-intercept is 4.
Step-by-step explanation:
First graph 4 on the y-axis (0,4). From there your going to up by 2, and right 1. Keep going until you can’t graph no more. Now go back to your point (0,4) go backwards now so Down 2, left 1. Graph until you can’t anymore. And your done! Make sure to add arrows and write down the equation on the line.

Ellie and Jamie like to bake cookies. Ellie baked 24 chocolate chip cookies, and Jamie baked p peanut butter cookies. Together they baked a total of 56 cookies. Write an equation that can be solved for p to find the number of cookies Jamie baked? A) 24/p = 56 B) p - 24 = 56 C) p + 24 = 56 B) 24p = 56
Answer:
C) p + 24 = 56
Step-by-step explanation:
The total number of cookies baked = Number of cookies Ellie baked + Number of cookies Jamie baked
Ellie baked 24 chocolate chip cookies.
Jamie baked p peanut butter cookies.
Total of 56 cookies.
Hence:
56 = p + 24
Therefore, the equation that can be solved for p to find the number of cookies Jamie baked is
p + 24 = 56
Option C is the correct option

For each sequence find the first four terms and the tenth term 3n-4
Answer:
= 1, 2, 5, 8 and 26
Step-by-step explanation:
To find the first 4 terms, substitute n = 1, 2, 3, 4 into the formula
a₁ = 3(1) - 4 = 3 - 4 = - 1
a₂ = 3(2) - 4 = 6 - 4 = 2
a₃ = 3(3) - 4 = 9 - 4 = 5
a₄ = 3(4) - 4 = 12 - 4 = 8
The first 4 terms are
- 1, 2, 5, 8
Substitute n = 10
a₁₀ = 3(10) - 4 = 30 - 4 = 26
Answer:
Below.
Step-by-step explanation:
We get the first 4 terms by plugging in n = 1 2 3 and 4:
3(1) - 4 = -1 , 3(2) - 4 = 2 ...
First 4 terms are
-1, 2, 5, 8
10th term = 3(10) -4 = 26.

SOLVE FOR THE BLANKS. PREFERABLY WITH STEPS SHOWN.
Thank you
Answer:
[tex]T(x)= 0.04x^2+64x+142[/tex]
Step-by-step explanation:
Sum of Functions
We are given the functions for the cost of two generators:
[tex]C(x) = 0.03x^2+26x+24[/tex]
[tex]K(x) = 0.01x^2+38x+118[/tex]
We are required to find the function for the sum of the costs of the two generators:
T(x)= C(x)+K(x)
We'll add both functions:
[tex]T(x)= 0.03x^2+26x+24+ 0.01x^2+38x+118[/tex]
To find the sum of both functions, we collect like terms:
[tex]T(x)= (0.03+0.01)x^2+(26+38)x+(24+118)[/tex]
[tex]\boxed{T(x)= 0.04x^2+64x+142}[/tex]
If a point is translated down 6 units, what are the new coordinates expressed as an algebraic representation?
Answer:
(x , y - 6)
Step-by-step explanation:
The y-axis deals with up and down motions. To shift a point downwards six units, subtract 6 from the value do the y-coordinate.
5.Footlocker buys Air Jordans for $30 a pair. They mark it up 75%. How much is the mark-up on a pair of Air Jordans
If you buy a pair of Air Jordans as mentioned in question #5, how much would you end up paying? (Hint: original amount + mark-up amount)
Answer:
$52.50
Step-by-step explanation:
What you do is you move the decimal two times to the left from 75%.
0.75*?=?
Take the orginal price and multiply ($30) by 0.75.
0.75*30= $22.50
Take 22.50 and add that to your original amount.
$22.50+$30= $52.50 or $52.5

Which answer best describes the system of equations shown in the graph?
Inconsistent
Consistent and independent
Consistent and dependent
Answer:
we conclude that the given system of equations is consistent and independent.
Hence, option B is true.
Step-by-step explanation:
From the figure it is clear that the two lines intersect at one point.
In other words, there is only one point of intersection of the given system of equations.
It means the system of equations contains exactly one solution.
We know that If a consistent system contains exactly one solution, it is termed as an independent.
Therefore, we conclude that the given system of equations is consistent and independent.
Hence, option B is true.

pa sagot po please need help
Answer:
Step-by-step explanation:
1). f(x) = 2x
f(-3) = 2(-3) = -6
f(1) = 2(1) = 2
f(4) = 2(4) = 8
Ordered pairs → (-3, -6), (1, 2), (4, 8)
2). f(x) = 2x + 1
f(-3) = 2(-3) + 1 = -5
f(1) = 2(1) + 1 = 3
f(4) = 2(4) + 1 = 9
Ordered pairs → (-3, -5), (1, 3) and (4, 9)
x -3 1 4
f(x) -5 3 9
3). f(x) = -3x
f(-3) = -3(-3) = 9
f(1) = -3(1) = -3
f(4) = -3(4) = -12
Ordered pairs → (-3, 9), (1, -3), (4, -12)
x -3 1 4
f(x) 9 -3 -12
