We know that the net signed area between f(x)=4x−8 and the x-axis over the interval [−5,6] is 46.
Given the function f(x)=4x−8, we need to find the net signed area between f(x) and the x-axis over the interval [−5,6].
To do this, we need to first plot the graph of the function f(x)=4x−8.
The graph of the function is a straight line passing through the y-axis at −8 and with a slope of 4.
Next, we need to find the x-intercepts of the function. To do this, we set f(x)=0 and solve for x.
0=4x−8
4x=8
x=2
So the x-intercept of the function is (2,0).
Now we can find the net signed area between f(x) and the x-axis over the interval [−5,6].
The interval [−5,6] includes the x-intercept at x=2.
The area below the x-axis from x=−5 to x=2 is given by the integral ∫−5^2 f(x)dx.
∫−5^2 (4x−8)dx = [2x^2−8x]−5^2 = [(2×2^2−8×2)−(2×(−5)^2−8×(−5))]
= [−4−(−90)] = 86
The area above the x-axis from x=2 to x=6 is given by the integral ∫2^6 f(x)dx.
∫2^6 (4x−8)dx = [2x^2−8x]2^6 = [(2×6^2−8×6)−(2×2^2−8×2))]
= [44−4] = 40
Therefore, the net signed area between f(x) and the x-axis over the interval [−5,6] is 86−40=46.
So the answer is: The net signed area between f(x)=4x−8 and the x-axis over the interval [−5,6] is 46.

Write an solve the inequality. A gym charges a one time sign-up fee of $10.25 and then $5 each time you go. A student can pay up to $135.25. How many times can the student go to the gym?
Answer:
25 visits
Step-by-step explanation:
Given data
One time fee= $10.25
let the number of times visited be x
and the total cost for x visits be y
Hence
y=10.25+5x------------1
for y=135.25
let us find x
135.25= 10.25+5x
135.25-10.25= 5x
125=5x
x= 125/5

Can someone please help me ASAP
Answer:
Look down below!
Step-by-step explanation:
Fist, make your inequality:
-x + 5y > -10
5y > x - 10
y = .2x - 2
Now, plug in any value of x to find y!
Ex: x = 5...
y = .2 (5) - 2
y = -1
Your first coordinate could be (5, -1)

Since it shows us that both ends of the segment in the middle bisects the sides of the triangle in the middle, we know that the segment in the middle is half of the hypotenuse (4x + 20).
[tex]\tt a)~ 3x =\frac{1}{2} (4x+20)[/tex]
Let's solve the right side of the equation by distributing[tex]\tt 0.5 (4x+20)\\4x*0.5=2x\\20*0.5=10\\\\b)~2x+10;~3x=2x+10[/tex]
Now, we can solve for x by moving the variable x to one side of the equation and everything else on the other side.
[tex]\tt 3x-(2x)=2x-(2x)+10\\\\c)~x=10[/tex]

Apples are on sale at the local fruit stand at 4 lbs. for $2.60. Which equation can be used to find the cost, c, of n pounds of apples?
c = 4
c = .65n
c = 2.60n
c = 8n
Answer:
B ) c = 0.65n
Step-by-step explanation:
To find how much a single pound costs, divide the total cost by the total weight (2.60 ÷ 4). So, the cost (c), equals $0.65 per pound.

Answer:
The answer is B. M'(-6,9) and N'(3,9)
Step-by-step explanation:
To find the coordinates of the endpoints of segment M'N' you'll have to use the rule through which it was dilated.
M(-4,6) after the rule it will be (-4*1.5, 6*1.5) = M'(-6,9)
N(2,6) after the rule it will be (2*1.5, 6*15) = N'(3,9)
The answer is B. M'(-6,9) and N'(3,9)
Hope this helps :)
The required endpoint of the segment M'N' is given as M'(-6,9) and N'(3,9) respectively. Option B is correct.
What is coordinate?Coordinate, is represented as the values on the x-axis and y-axis of the graph. while the coordinate x is called abscissa and the coordinate of the y is called ordinate.
Here,
The equation for the dilation is given as,
= {1.5x, 1.45y}
Now,
Put coordinates of M and N in the above equation,
Coordinate of M' = (-4×1.5, 6×1.5) = M'(-6,9)
Similarly, the coordinate of N',
Coordinate of N' = (2×1.5, 6×1.5) = N'(3,9)
Thus, the required endpoint of the segment M'N' is given as M'(-6,9) and N'(3,9) respectively. Option B is correct.

Find the square root. 1/16
Answer:
The square root of 1/16 is 1/4=0.25
Step-by-step explanation:
The square root of 1/16 is 1/4.
To find the square root of 1/16, you can take the square root of the numerator and the denominator separately.
√(1/16) = √1 / √16
Since the square root of 1 is 1, and the square root of 16 is 4:
