2) b
Step-by-step explanation:
1) translated 6 units to the left will be negative = x-6
5 units up will be positive = y+5
2) when reflecting across the x-axis, the x-values of each original point will remain the same and the y-values will become opposite. For example one point is (-5, 3) which will be (-5, -3) as the opposite of 3 is -3 which is in the form (x,-y)
Peyton invested \$1700$1700 in an account that pays 3.5% interest compounded annually. Assuming no deposits or withdrawals are made, find how much money Peyton would have in the account 15 years after her initial investment. Round to the nearest tenth (if necessary).
Based on the amount Peyton invested, and the interest rate, the amount in the account 15 years later would be $2,848.09.
How much would be in the account after 15 years?The amount in the account after 15 years would be:
= Amount x ( 1 + rate) ^ number of years
Solving gives:
= 1,700 x ( 1 + 3.5%)¹⁵
= $2,848.09

Ben and Landon took turns driving on a 820 mile road trip. Ben averaged 60 miles per hour and Landon averaged 56 miles per hour. The trip took them 14 hours. How many hours did Landon drive?
Answer:
See below!
Explanation:
distance = speed * timespeed = distance/timetime = distance/speedequation for distance:
Lets Ben hours be x and Landon hours be y,
60x + 56y = 820 .........equation 1
equation for time:
[tex]\frac{60x}{60}+ \frac{56x}{56} =14[/tex]
x + y = 14 .........equation 2
Make x the subject:
60x + 56y = 820
x = (820 - 56y)/60 ..........equation 3
x + y = 14
x = 14 - y ........equation 4
Solve equation 3 and 4 simultaneously:
14 - y = (820 - 56y)/6060(14 - y) = 820 - 56y840 - 60y = 820 -56y840 - 820 = -56y + 60y20 = 4yy = 5[ Therefore Landon drove 5 hours ]
Extra's further investigated:
if y = 5
x = 14 - yx = 14 - 5x = 9[ Therefore Ben drove 9 hours ]
Answer:
Landon drove 5 hours (and Ben drove 9 hours)
Step-by-step explanation:
Let B = number of miles Ben drove
Let L = number of miles Landon drove
Given The trip took them 14 hours
⇒ B + L = 14
Given, Ben averaged 60 miles per hour and Landon averaged 56 miles per hour. Ben and Landon took turns driving on a 820 mile road trip:
⇒ 60B + 56L = 820
Rewrite B + L = 14 to make B the subject, substitute into 60B + 56L = 820, and solve for L:
⇒ B = 14 - L
⇒ 60(14 - L) + 56L = 820
⇒ 840 - 60L + 56L = 820
⇒ 20 = 4L
⇒ L = 5
Therefore, Landon drove for 5 hours

Answer:
1. Paul has mixed up the translation of the ordered pair.
New location: (1, 5)
2. Option C : E = (3, 2) F = (8, 4) G = (5, 7)
Step-by-step explanation:
An ordered pair is a pair of numbers, (x,y) , written in a particular order.
It is often used to represent a point on a coordinate plane.
1. From inspection of the diagram, the market is located at (3, 8)
Paul's mistake is that he has mixed up the translation of the ordered pair. He has moved the market 3 to the left and 2 units down instead of the required 2 to the left and 3 units down.
The correct ordered pair for the new location of the market is (1, 5)
2. For each coordinate point (x, y), the first number is the x-coordinate (along the x-axis) and the second number is the y-coordinate (along the y-axis).
E = (3, 2)
F = (8, 4)
G = (5, 7)

1/3 = x/15
15/3 = x = 5
question 2
8/y = 4/6
8×6 = 4y

Triangle ABC is shown on the grid below.
Which value best represents the length of AB?
a 8 units
b 12 units
c 15 units
d 21 units
Answer:
15 units
Step-by-step explanation:
you have to use pythagoras to solve (c²=a²+b²)
AB is the longest side of the triangle which is c in the pythagoras
so counting the units for AC, you get 9 units, and CB you get 12 units
now solve for c in pythagoras
c²=9²+12²
c = 15 units

Answer:
B
Step-by-step explanation:

The figure is made up of 2 rectangles and 2 right triangles
What is the area of this figure
132 units^2
156 units^2
168 units^2
216 units^2
Answer:
total area = 132 units²
Step-by-step explanation:
Area of a rectangle = width x heightArea of a triangle = 1/2 x base x height
Area of largest rectangle = 4 x 15 = 60 units²
Area of smallest rectangle = 4 x 6 = 24 units²
Area of largest triangle = 1/2 x (15 - 6) x (4 + 4) = 36 units²
Area of smallest triangle = 1/2 x 6 x 4 = 12 units²
Total area of the figure = sum of areas of 2 rectangles and 2 triangles
⇒ area = 60 + 24 + 36 + 12 = 132 units²

Step-by-step explanation:
The function y = f (x) is linear.
Given f-¹ (0) = 3 and f (1) = - 4, find the formula of
f (x) and f-¹ (x)
Answer:
[tex]f(x)=2x-6[/tex]
[tex]f^{-1}(x)=\dfrac{x+6}{2}[/tex]
Step-by-step explanation:
Using slope-intercept form of linear function: [tex]y = mx + b[/tex]
[tex]\implies f(x)=mx+b[/tex]
[tex]\textsf{if} \ \ f(1) = -4[/tex]
[tex]\implies m + b=-4[/tex]
[tex]\implies b = -4-m[/tex]
Find inverse of slope-intercept form:
swap x and y: [tex]x = my + b[/tex]
Make y the subject:
[tex]\implies x - b = my[/tex]
[tex]\implies y = \dfrac{x-b}{m}[/tex]
[tex]\implies f^{-1}(x) = \dfrac{x-b}{m}[/tex]
[tex]\textsf{if} \ \ f^{-1}(0) = 3[/tex]
[tex]\implies \dfrac{0-b}{m}=3[/tex]
[tex]\implies b=-3m[/tex]
[tex]\textsf{equation 1:} \ \ b = -4-m[/tex]
[tex]\textsf{equation 2:} \ \ b=-3m[/tex]
Equate the equations and solve for [tex]m[/tex]:
[tex]\implies b=b[/tex]
[tex]\implies -4-m=-3m[/tex]
[tex]\implies -4=-2m[/tex]
[tex]\implies m=2[/tex]
Substitute found value for [tex]m[/tex] into one of the equations and solve for [tex]b[/tex]:
[tex]b = -4-2=-6[/tex]
Substitute found values of [tex]m[/tex] and [tex]b[/tex] into equations for [tex]f(x)[/tex] and [tex]f^{-1}(x)[/tex]:
[tex]f(x)=2x-6[/tex]
[tex]f^{-1}(x)=\dfrac{x+6}{2}[/tex]

math question helppp
Answer:
1st row = 10 = y
2nd row = 12 = y
3rd row = 18 = y
4th row = 22 = y
Step-by-step explanation:
Given:
y = 4x + 6
since the y-intercept is 6, we know that when the input value(x) is equal to 0, the output value(y) is equal to 6.
so now we plug in the equation for each row,
starting with the first one.
in the first row it says x is equal to 1 so the equation would look like this:
y = 4(1) + 6
simplified the equation to get
y = 4 + 6 = 10
meaning for the first row, y = 10!
since the x value is constant, and only goes up by 1 each row, this means we can just add 4 more each time.
However, I am going to write the equation for each row anyways.
Second row:
y = 4(2) + 6
simplifys into
y = 8 + 6 = 12
y = 12
Third row:
y = 4(3) + 6
simplifys into
y = 12 + 6 = 18
y = 18
Fourth row:
y = 4(4) + 6
simplifys into
y = 16 + 6 = 22
y = 22
So to recap, the answers to each row are...
1st row = 10 = y
2nd row = 12 = y
3rd row = 18 = y
4th row = 22 = y

Explanation:
Given Sides:
HB = 6HD = 6+15 = 21HM = 9HT = 9 + x-----------------------------
using all these sides, create similarities equation:
[tex]\frac{HB}{HD} = \frac{HM}{HT}[/tex]
[tex]\frac{6}{21} = \frac{9}{9+x}[/tex]
[tex]6(9+x) = 9(21)[/tex]
[tex]54 + 6x = 189[/tex]
[tex]6x = 189 - 54[/tex]
[tex]6x = 135[/tex]
[tex]x = \frac{135}{6}[/tex]
[tex]x = 22.5[/tex]

Graph this line using the slope and y-intercept: y = 1/8x + 4
(1/8 is a fraction)
Answer:
Two points, (0,4) & (8,5)
Step-by-step explanation:
In this equation, we can easily find the first point by looking at the +4 in this equation. This should automatically signal to you that the point is (0,4)
Now, we have to look at the 1/8x in the equation.
This 1/8 means that the slope is 1/8!
Now we use the slope and to rise/run to find our next point
We go up 1 from 4 (this is the rise) to get to 5 on the y-axis
Next, we go over 8 horizontally to get to 8 for your x-axis point.
So therefore, our next point is, (8,5)
You can use this rise/run system infinitely and is very useful
Write the equation of the line in fully simplified slope-intercept form.
Answer:
y = - 6x - 8
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (- 3, 10) and (x₂, y₂ ) = (- 1, - 2) ← 2 points on the line
m = [tex]\frac{-2-10}{-1-(-3)}[/tex] = [tex]\frac{-12}{-1+3}[/tex] = [tex]\frac{-12}{2}[/tex] = - 6
the line crosses the y- axis at (0, - 8 ) ⇒ c = - 8
y = - 6x - 8 ← equation of line
