Pedro and John are going on a field trip with school. Together the boys have $62 to spend on the trip. If Pedro has $15 more than John, how much money does John have? Write a function rule (equation) that represents the situation.
Answer:
John has $23.5Step-by-step explanation:
Step one:
we are told that their joint amount is $62
let John's amount be x
and Pedro's amount be y
so that y=x+15
Step two:
The equation to represent the situation is
62=x+(x+15)
open the bracket and solve for x we have
62=x+x+15
62=2x+15
2x=62-15
2x=47
divide both sides by 2
x=47/2
x=23.5
John has $23.5

Answer:
The correct options are presented as follows;
ΔABC is reflected across the y-axis to become ΔA'B'C' is rotated 90° counterclockwise about the origin to become ΔA''B''C''. Because the transformations are rigid transformations the preimage and image are congruent
Step-by-step explanation:
The coordinate of the preimage point A = (-2, 1)
The coordinate of the image point A' = (2, 1)
Similar for points B(-5, -2) and B'(5, -2), C(-3, -4) and C'(3, -4)
Which is equivalent to a reflection across the y-axis
Similarly, we have;
The coordinate of the preimage point A' = (2, 1)
The coordinate of the image point A'' = (-1, 2)
Which is equivalent to rotation of 90° counterclockwise which involves transforming a preimage (x, y) to an image (-y, x)
Similar for points B and B', C and C'
Therefore, because the reflection transformation, and the rotation transformation, are rigid transformation, the figures of the preimage and the image are congruent
Therefore, we have;
ΔABC is reflected across the y-axis to become ΔA'B'C' is rotated 90° counterclockwise about the origin to become ΔA''B''C''. Because the transformations are rigid transformations the preimage and image are congruent.
Edward deposited $9,500 into savings account 2 years ago. The simple interest rate is 4%. How much money did Edward earn in interest ? What would be his new account balance
Answer:
$760 earned in intrest
$10260 new account balance
Step-by-step explanation:
First we have to find 4% of 9500
use the formuala
[tex]\frac{4}{100} =\frac{x}{9500}[/tex]
4×9500=38000
38000÷100=380
now 380×2=760
add 760 to 9500 for new account balance

Three pumpkins are catapulted at a contest. How much farther does Pumpkin C travel than Pumpkin A? • Pumpkin A travels 0.61 mile. • Pumpkin B travels 0.28 mile farther than Pumpkin A. • Pumpkin B travels 0.06 mile farther than Pumpkin C.
Answer:
0.22 miles
Step-by-step explanation:
Let
A = Distance pumpkin A travels = 0.61 miles
Distance pumpkin B travels is 0.28 mile farther than Pumpkin A
[tex]B=0.28+A\\\Rightarrow B=0.28+0.61\\\Rightarrow B=0.89\ \text{miles}[/tex]
Distance pumpkin B travels is 0.06 miles further than pumpkin C
[tex]B=0.06+C\\\Rightarrow C=B-0.06\\\Rightarrow C=0.89-0.06\\\Rightarrow C=0.83\ \text{miles}[/tex]
To calculate how much farther pumpkin C travels than pumpkin A we have the subtract their distances
[tex]C-A=0.83-0.61=0.22\ \text{miles}[/tex]
So, pumpkin C traveled 0.22 miles more than pumpkin A.
-2x-5=4 solve for x and please tell me how you got it
Answer:
x = -9/2 or -4.5
Step-by-step explanation:
-2x-5=4
Add 5 to each side
-2x-5+5=4+5
-2x = 9
Divide each side by -2
-2x/-2 = 9/-2
x = -9/2 or -4.5

Question 2 (2 points)

Using the graph below, calculate the average rate of change for f(x) from x = 0 to x=2.
a: x=-4
b: x=-2
c: x= 2
d: x= 4
Answer:
Option (D)
Step-by-step explanation:
Formula to get the average rate of change of the function f(x) between two points x = a and b is,
Average rate of change = [tex]\frac{f(b)-f(a)}{b-a}[/tex]
We have to calculate the average rate of change between x = 0 and x = 2.
From the graph attached,
f(0) = -2
f(2) = 6
Therefore, average rate of change = [tex]\frac{6-(-2)}{2-0}[/tex]
= [tex]\frac{8}{2}[/tex]
= 4
Option (D) will be the correct option.
PLZ HELP! WILL MARK BRAINLIEST!! The graphs of linear functions f and g are shown on the graph. Which function is best represented by the graph of g?
A. g(x) =f(x)-4
B. g(x) = 1/3 f(x)
C. g(x) = f(x)-2
D. g(x)=3f(x)
Answer:
B
Step-by-step explanation:
f(x)=x (slope is 1, y-intercept is zero)
g(x) = (1/3)x (slope is (1/3), y-intercept is zero)
(1/3)x = (1/3)f(x)
Answer:
B
Step-by-step explanation:
as u notice the slop of f function is higher than g function so g(x) is approximately one third of function f and there are no shifts in g(×) so no need for sum of subtract .
