Step-by-step explanation:
Write an absolute value equation that has the solutions $x=8$ and $x=18$
Answer:
Step-by-step explanation:
Let |x-a|=b
then x-a=±b
so x-a=b
or x=a+b
so a+b=18 ...(1)
and x-a=-b
or x=a-b
or a-b=8 ...(2)
adding (1) and (2)
2a=26
a=26/2=13
subtract (2) from (1)
2b=10
b=10/2=5
|x-13|=5
Solve the equation for a 62=a(25-0)(25-50)

Answer:
A) The first checkbox
B) The first and third checkbox
Step-by-step explanation:
A) [tex]\frac{-5}{-4}[/tex] ⇒ the negative would cancel/cross out and leave you with [tex]\frac{5}{4}[/tex]
B) Look for one negative sign in either the numerator or denominator.
Write an equation in slope-intercept form for the line that passes through the point ( 2 , 3 ) and is perpendicular to the line − 5 x + 4 y = − 3 .
The slope of a line in standard equation will be [tex]\frac{-A}{B}[/tex]
[tex]m=\frac{5}{4}[/tex]
The slope of a perpendicular line to this line will be opposite and reciprocal.
[tex]m=-\frac{4}{5}[/tex]
Then, we can plug in the point given to get the [tex]b[/tex] value.
[tex]3=-\frac{4}{5}(2)+b[/tex]
[tex]3=-\frac{8}{5}+b[/tex]
[tex]b=\frac{23}{5}[/tex]
[tex]y=-\frac{4}{5}x+\frac{23}{5}[/tex]
Hope this helps.

58 POINTS!!! The line contains the point (8,2) and is parallel to a line with a slope of -2/3 The equation of the line is
Answer:
The answer is
[tex]y = - \frac{2}{3} x + \frac{22}{3} [/tex]Step-by-step explanation:
Equation of a line is y = mx + c
where
m is the slope
c is the y intercept
Since the lines are parallel their slope are also the same
So the slope of parallel line = - 2/3
So the equation of the line containing the point (8 , 2) and slope - 2/3 is
[tex]y - 2 = - \frac{2}{3} (x - 8) \\ y - 2 = - \frac{ 2}{3} x + \frac{16}{3} \\ y = - \frac{2}{3} x + \frac{16}{3} + 2[/tex]
We have the final answer as
[tex]y = - \frac{2}{3} x + \frac{22}{3} [/tex]Hope this helps you
Slope intercept form: y = mx + b
Parallel lines have the same slope, so the slope is -2/3.
We can solve using point slope form.
y - 2 = -2/3(x - 8)
y - 2 = -2/3x + 16/3
y = -2/3x + 22/3

There are five consecutive odd integers. The sum of the three smallest is 3 more than the sum of the two largest. Find the integers. 15 points
Answer:
11 13 15 17 19
Step-by-step explanation:
We will solve this word problem using 2k+1 which is one of the general forms of an odd integer.
Let 2k+1 be the first odd integer.
(2k+1) + (2k+3) + (2k +5) = (2k+7) + (2k +9) + 3 (the +3 is to accommodate for the left side being 3 more than the right)
Solve for k
6k + 9 = 4k + 19
6k - 4k + 9 = 4k-4k + 19
2k + 9 = 19
2k + 9 - 9 = 19 - 9
2k = 10
2k/2 = 10/2
k = 5
To get the first digit in the series plug in 5 for k
2k+1
2(5) + 1
10 + 1 = 11
So our series is 11, 13, 15, 17, 19
Let's test it.
11 + 13 +15 = 39
17 + 19 = 36
So we are correct, the first 3 integers are 3 more that the sum of the last 2.
Answer:
11, 13, 15, 17, 19

p: Two linear functions have different coefficients of x.
q: The graphs of two functions intersect at exactly one point.
Which statement is logically equivalent to q-p?
If two linear functions have different coefficients of x, then the graphs of the two functions intersect at exactly one
point.
O If two linear functions have the same coefficients of x, then the graphs of the two linear functions do not intersect
at exactly one point.
If the graphs of two functions do not intersect at exactly one point, then the two linear functions have the same
coefficients of x.
O If the graphs of two functions intersect at exactly one point, then the two linear functions have the same
coefficients of x.
Answer:
Linear function A and linear function B both have the same input values as shown below. Why will the output values for linear function A always be different than the corresponding output values for linear function B? The initial values of the two functions are different, and the rates of change of the two functions are also different. The initial values of the two functions are different, and the rates of change of the two functions are the same. The initial values of the two functions are the same, and the rates of change of the two functions are different. The initial values of the two functions are the same, and the rates of change of the two functions are also the same.

Since cos(x) is the derivative of sin(x), then integral 16 sin^2(x) cos(x) dx can be done by substituting u = sin (x) sin (x) and du = cos (x) cos (x)^dx. With the substitution u = sin(x), we get integral 16 sin^2 (x) cos(x) dx = 16 integral u^2 du. which integrates to + C. Substituting back in to get the answer in terms of sin(x), we have integral 16 sin^2 (x) cos (x) dx = + C.

Find the integral of [tex]f(x) = 16sin^2 (x ) cos(x) dx[/tex]
Answer:
The solution is [tex]\frac{16}{3} sin^{3}x + c[/tex]
Step-by-step explanation:
So
[tex]Let \ u = sin(x)[/tex]
=> [tex]\frac{du}{dx} = cos (x)[/tex]
=> [tex]du = cos(x)dx[/tex]
So
[tex]\int\limits {16sin^2 (x ) cos(x) dx} \, \equiv \int\limits {16u^2 du}[/tex]
=> [tex]\int\limits {16u^2 du} = 16 [\frac{u^3}{3} ] + c[/tex]
Now substituting sin(x) for u
[tex]\frac{16}{3} u^3 + c = \frac{16}{3} sin^{3}x + c[/tex]
So the integral of [tex]f(x) = 16sin^2 (x ) cos(x) dx[/tex] is
[tex]\frac{16}{3} sin^{3}x + c[/tex]

The table shows the values of two quantities for an astronaut on Earth and Earth's moon. Which of the following names the quantity and correctly explains why that represents the astronaut's mass? Quantity A, because it remains the same throughout Quantity B, because it is independent of other quantities Quantity B, because it changes with gravitational strength Quantity A, because it measures the force acting on the astronaut
Answer:
A.
Step-by-step explanation:
the answer is A. because in space, the whole thing is the same amount of density. except for the sun but the question says earth and moon. hop this helps!!! please give me brainliest answer!!!
Quantity A because it changes with gravitational pull.
Given that, the Astronaut's mass of quantity A on earth is 70 units and on the moon is 70 units.
The Astronaut's mass of quantity B on earth is 686 units and on the moon is 112 units.
What happens to an astronaut's mass in space?We can measure weight here on Earth, but not in the microgravity environment on the International Space Station. Mass plays a critical role in the activities and experiments performed by the astronauts. Mass does not change whether it is measured on Earth or the ISS.
Now, mass defines the constitutive matter of an object. It is immutable (does not change). Although it could be converted into energy, the matter is constant.
On the other hand, the weight of an object (gravitational force) depends on the acceleration due to gravity.
That is why an astronaut weighs about three times more on earth than on Mars. The gravitational acceleration on Mars is about one-third that on earth.
Therefore, Quantity A because it changes with gravitational pull.
