Lori graphed f(x) = -34x – 1 and g(x) = -4f(x) on the same coordinate grid. Which statement below incorrectly describes how the graphs of f(x) and g(x) are related?
A:The graph of f(x) is less steep than the graph of g(x)
B:The graph of f(x) is shifted 4 units up to create the graph of g(x).
C:The graph of f(x) has the same x-intercept as the graph of g(x)
D:The y-intercept of f(x) is 5 units below the y-intercept of g(x).
Answer:
C
Step-by-step explanation:
I’m on a test and graphed this
The statement that incorrectly describes how the graphs of f(x) and g(x) are related is B:The graph of f(x) is shifted 4 units up to create the graph of g(x).
The function f(x) is given as:
f(x) = -34x – 1
The function g(x) is given in terms of f(x) as:
g(x) = -4f(x)
Substitute f(x) = -34x - 1 into g(x)
g(x) = -4(-34x - 1)
g(x) = 136x + 4
Find the x-intercept of f(x)
Let f(x) = 0
0 = -34x - 1
x = -1/34
The x-intercept of f(x) = (-1/34, 0)
Find the x-intercept of g(x)
Let g(x) = 0
0 = 136x + 4
x = -4/136
x = -1/34
The x-intercept of g(x) = (-1/34, 0)
It is true that the graph of f(x) has the same x-intercept as the graph of g(x)
The y-intercept of f(x) is -1 and the y-intercept of g(x) = -4
It is true that the y-intercept of f(x) is 5 units below the y-intercept of g(x)
The slope with a greater absolute value is steeper.
The slope of g(x) is greater than that of f(x), therefore, the graph of g(x) is steeper.
The only incorrect statement is option B. The graph of f(x) is shifted 4 units up to create the graph of g(x)

Answer:
The value of a = -12
Step-by-step explanation:
Given the equation
[tex]\frac{8^{-55}}{8^a}=8^{-43}[/tex]
Determining the value of a
Given the equation
[tex]\frac{8^{-55}}{8^a}=8^{-43}[/tex]
Apply the exponent rule: [tex]\frac{x^a}{x^b}=x^{a-b}[/tex]
[tex]\:8^{-55-a}=8^{-43}[/tex] ∵ [tex]\frac{8^{-55}}{8^a}=8^{-55-a}[/tex]
[tex]-55-a = -43[/tex]
Add 55 to both sides
[tex]-55-a+55=-43+55[/tex]
Simplify
[tex]-a=12[/tex]
Divide both sides by -1
[tex]\frac{-a}{-1}=\frac{12}{-1}[/tex]
Simplify
[tex]a=-12[/tex]
Therefore, the value of a = -12

I need help with a geometry problem! It’s about reflection
Step-by-step explanation: Here, we're asked to reflect ΔQRS over
the x-axis so we begin by reflecting point Q over the x-axis.
Since point Q is 2 units below the x-axis, point Q will reflect
over the x-axis to a position 2 units above the x-axis.
We label this point as Q' which is the ordered pair (1, 2).
Next we reflect point R over the x-axis.
Since point R is 2 units below the x-axis, point R will reflect
over the x-axis to a position 2 units above the x-axis.
We label this point as R' which is the ordered pair (3, 2).
Now connect the points to get our reflection.
Next we reflect point S over the x-axis.
Since point S is 6 units below the x-axis, point S will reflect
over the x-axis to a position 6 units above the x-axis.
We label this point as S' which is the ordered pair (1, 6).

Let x be the speed of Aro’s paddling and let y be the speed of the river.
Upstream: 1.04 = x – y
Downstream: 2.08 = x + y
Aro can paddle at a speed of
miles per hour.
The river’s speed is
miles per hour.
Answer:
Aro can paddle at a speed of 1.56 miles per hour.
The river’s speed is 0.52 miles per hour.
Step-by-step explanation:
trust
The solution of the given system of equation x - y = 1.04 and x + y = 2.08 are x = 1.56 and y = 0.52 thus Aro can paddle at a speed of miles per hour is 1.56 and The river’s speed in miles per hour 0.52.
What is the equation?There are many different ways to define an equation. The definition of an equation in algebra is a mathematical statement that demonstrates the equality of 2 mathematical expressions.
As per the given,
x = speed of Aro
y = speed of River
x - y = 1.04
x + y = 2.08
Add both equations,
2x = 3.12
x = 1.56
And, y = 1.56 - 1.04 = 0.52
Hence "The solution of the given system of the equation x - y = 1.04 and x + y = 2.08 are x = 1.56 and y = 0.52 thus Aro can paddle at a speed of miles per hour is 1.56 and The river’s speed in miles per hour 0.52".

Answer:B
Step-by-step explanation:
what is y?
4y-2x+6=26
how do i show my work?
im not sure if im correct but y could be 6 because if u multiply 4 by 6 its 24 and x is 2 so 2 times 2 is 4 and if we subtract 4 from 24 its 20 plus 6 its equals 26
how to show work:
y=6 x=2
4y - 2x + 6 = 26
4x6=24 - 2x +6 =26
24 - 2x2=4 +6 =26
24 - 4 + 6=26

Lisa collected data on the grams of fat and the grams of carbohydrates in 10 sandwiches at a popular restaurant. The table below represents the data she recorded.
Which linear equation best fit Lisa’s data?
A. y=0.5x + 23
B. y=23x+ 0.5
C. y=1.5x+ 27
D. y=27x + 1.5
Answer:
A. y=0.5x + 23Step-by-step explanation:
Take two random pairs from the table and find the formula:
(12, 32) and (24, 36)Find the slope:
m = (36 - 32)/(24 - 12) = 4/12 = 1/3Find y-intercept:
12*1/3 + b = 32b = 32 - 4 = 28b = 28The line is:
y = 1/3x + 28The best fit is A. y = 0.5x + 23, the other options have too much of difference in the slope or y-intercept
