Find the inverse function. f(x) = x - 5
Answer:
f^-1 (x) = x^2 + 5
Step-by-step explanation:
f(x) = √x - 5
replace x with y
x= √y - 5
solve for y,
x =√y-5
x^2 + 5
Answer -
f^-1(x) = x^2 + 5

Use the GCF and the Distributive Property to find the sum. 26+39
Answer:
65--but the method is the important part that the directions indicated.
Step-by-step explanation:
26 + 39
(2 × 13) + (3 × 13)
The GCF is 13.
Factor the 13 out; it's like Distributive Property in reverse.
13 (2 + 3)
13 (5)
65
26+39= 65, so we obtain the same answer as just adding, by using GCF and Distributive Property.
Answer:
13(2 +3)
Step-by-step explanation:
26 = 2·13
39 = 3·13
The greatest common factor is 13, so the sum can be written ...
26 +39 = 13(2 +3)
_____
Additional comment
Of course, the value of the sum is ...
13(2+3) = 13(5) = 65
Alternatively, the sum can be evaluated as ...
26 +39 = 26 -1 +1 +39 = (26 -1) +(1 +39) = 25 +40 = 65

Step-by-step explanation:
I cannot draw here, but I can show and tell you how to find 2 points of the individual lines that you can then mark on the chart and draw the line through them.
1)
y = 7/2 x - 2
so, the first and easiest point is the y-intercept (where x = 0).
x = 0, therefore, y = -2
so, the first point is (0, -2)
for the second point : what value of x would eliminate the fraction and make this whole integer number calculations ?
well, x = 2 !
so,
y = 7/2 × 2 - 2 = 7 - 2 = 5
and our second point is (2, 5)
2)
y = -6x + 3
the same principles. first x = 0, therefore y = 3
the first point is (0, 3)
for the second point we can choose any integer x, as all the other terms are integer too.
let's pick x = 1
y = -6×1 + 3 = -6 + 3 = -3
so, the second point is (1, -3)
3)
y = -5
this just means that for every possible value of x the resulting y value is -5.
that means it is a horizontal line through y = -5 or (0, -5)
4)
y = 6/5 x + 1
the same principles. x = 0, therefore y = 1
the first point is (0, 1)
for the second point, again, what x eliminates the fraction and makes all an integer operation ?
well, x = 5.
y = 6/5 × 5 + 1 = 6 + 1 = 7
ok, 7 is off the chart, so let's use x = -5 instead.
y = 6/5 × -5 + 1 = -6 + 1 = -5
so, the second point on the chart is (-5, -5)

Answer:
404
Step-by-step explanation:
do the equation inside the brackets first (BIDMAS) - 5 x 6 = 30
48 / 6 = 8
8 + (30 x 13) + 6 = 38
30 x 13 = 390

Calculate the distance between the points M=(-1,-2) and C=(-9, 2) in the coordinate plane.
Round your answer to the nearest hundredth.
Answer:
8.9443
Step-by-step explanation:
d = √((x2-x1)2 + (y2-y1)2)
Step by step procedure:
Find the difference between coordinates:
(x2-x1) = (-9 - -1) = -8
(y2-y1) = (2 - -2) = 4
Square the results and sum them up:
(-8)2 + (4)2 = 64 + 16 = 80
Now Find the square root and that's your result:
Exact solution: √80 = 4√5
Approximate solution: 8.9443

Answer:
y = 3x + 16
Step-by-step explanation:
If it is parallel to y = 3x + 8, then it has the same slope of 3.
y = 3x + b. Substitute the x and y values into the equation to solve for b.
7 = 3(-3) + b
7 = -9 + b
16 = b
y = 3x + 16

Suppose you are putting up a tent for a camping trip.
The 9 foot center pole makes a right angle with the ground. If a rope goes from the top of the pole to a point on the ground 12 feet away from the base of the pole. how long of a rope is needed?
The length of the rope needed is 15 feet
Given the following parameters;
Height of the pole = 9 footThe distance from the rope away from the base of the pole is 12 feetRequired
Length of the rope.To get the length of the rope, you will use the pythagoras theorem expressed as:
c² = a² + b²Substituting the given parameters:
c² = 9² + 12²
c² =81 + 144
c² = 225
c = √225
c = 15 feet
Therefore the length of the rope needed is 15 feet
