Answer:
Step-by-step explanation:
Yes, it can.
A 100% increase means it's the original amount plus the original amount (2x). 100+100=200
A 150% increase would be the original amount plus 1.5 times the original amount. 100+150=250
Answer:
It's impossible to give more than 100%, they'll say. That's what percent means. But of course percentages greater than 100 are possible. It all depends on what your baseline is — x percent of what.

The velocity v that an object r units
from Earth's center must have in
order to escape Earth's gravity is
given by v2 = 2GM, where G is a
constant. Solve for the object's
mass M.
Answer:
M=v^2r / 2G
Step-by-step explanation:
Open the file, it is solved for you, your welcome.
Earth's gravity for the object's mass M is [tex]M = \frac{v^{2} }{2G}[/tex].
Here,
The velocity v that an object r units from Earth's center must have in order to escape Earth's gravity is given by,
[tex]v^{2} = 2GM[/tex]
We have to find, Earth's gravity for the object's mass M.
What is Velocity?
The distance covered by a body in a unit time in a particular direction is called velocity.
Now,
Earth's gravity is given by,
[tex]v^{2} = 2GM[/tex]
In terms of mass M,
⇒ [tex]M = \frac{v^{2} }{2G}[/tex].
So, Earth's gravity for the object's mass M is [tex]M = \frac{v^{2} }{2G}[/tex].

x = 1 and x = 3
What is an expression?
Expression in math is defined as the collection of the number, variables and functions by using signs like addition, subtraction, multiplication, and division.
The absolute value equation is given as;
- |x - 4| + 2 = -2x + 7
Now, Solve the equation as;
- |x - 4| + 2 = -2x + 7
Subtract 2 both side,
- |x - 4| + 2 - 2 = -2x + 7 - 2
- |x - 4| = -2x + 5
Multiply by -1,
|x - 4| = 2x - 5
Since, the absolute value equation gives two equation as;
x - 4 = ± (2x - 5)
Take with positive sign;
x - 4 = 2x - 5
Add 4 both side,
x - 4 + 4 = 2x - 5 + 4
x = 2x - 1
2 x - x = 1
x = 1
And, Take with negative sign as;
x - 4 = - (2x - 5)
x - 4 = - 2x + 5
Add 4 both side,
x = -2x + 9
Add 2x both side,
x + 2x = 9
3x = 9
Divide by 3,
x = 3
Thus, The real solution of the absolute value equation are;
x = 1 and x = 3

What is factorization?Factorization is expressing a mathematical quantity in terms of multiples of smaller units of similar quantities.
For an integer, factorization is decomposition of that integer in terms of smaller integers which when multiplied with each other give back that considered number. Those composing integers are called factors of that considered integers.
Also Prime factorization is when all those factors are prime numbers.
Thus, this factorization expresses an integer in terms of multiples of prime numbers.

A salesperson receives a weekly salary plus a commission for each
computer sold. The table shows the total pay, p, and the number
of computers sold, n. Write an equation in slope-intercept form to
represent this situation.
Answer:
[tex] p = 75n + 250 [/tex]
Step-by-step explanation:
Equation of the situation, in slope-intercept form is given as [tex] p = mn + b [/tex].
Where,
b = y-intercept
m = slope
n = number of computers sold
p = total cost
All we need to find is the value of m and b.
Using two pairs from the table of values, (4, 550) and (6, 700):
[tex] slope(m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{700 - 550}{6 - 4} = \frac{150}{2} = 75 [/tex]
Substitute n = 4, p = 550, and m = 75 in [tex] p = mn + b [/tex], and find the value of b.
[tex] 550 = (75)(4) + b [/tex]
[tex] 550 = 300 + b [/tex]
Subtract 300 from each side
[tex] 550 - 300 = b [/tex]
[tex] 250 = b [/tex]
b = 250
Substitute m = 75, and b = 250 in [tex] p = mn + b [/tex]
✅Equation that represents the situation would be:
[tex] p = 75n + 250 [/tex]
The equation in slope-intercept form to represent this situation is (p = 75n + 250) and this can be determined by using the point-slope form of the line.
Given :
A salesperson receives a weekly salary plus a commission for each computer sold.The given table shows the total pay, p, and the number of computers sold, n.Use the formula of point-slope in order to determine the equation of a line. The point-slope form is given by the equation:
[tex]\dfrac{y-y_1}{x-x_1}=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
where [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] are the points on the line.
According to the given table, the points on the line are (4,550) and (6,700).
Substitute the value of [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] in the formula of point-slope form.
[tex]\dfrac{p-550}{n-4}=\dfrac{700-550}{6-4}[/tex]
Simplify the above expression.
[tex]\dfrac{p-550}{n-4}=\dfrac{150}{2}[/tex]
Cross multiply in the above equation.
(p - 550) = 75(n - 4)
p - 550 = 75n - 300
p = 75n + 250
The equation in slope-intercept form to represent this situation is (p = 75n + 250).

How is dividing each side of > x greater than 0 by a negative value different from dividing each side by a positive value?
Step-by-step explanation:
When you divide both sides of an inequality by a positive number, the inequality sign remains the same. When you divide both sides of an inequality by a negative number, you must reverse the inequality sign.
For example:
8 > 2 is a true inequality.
Let's divide both sides by 2:
4 > 1 is also a true inequality. The inequality sign remained > since we divided by a positive number.
Now let's start again with
8 > 2, and divide both sides by -2.
-4 > -1 is false. When the inequality sign remains the same after dividing both sides by a negative number, the inequality is no longer true. To keep the inequality true, we must change the inequality sign when dividing both sides by a negative number.
8 > 2
Divide both sides by -1.
-4 < -1 is true.
Solve for m in terms of a, b, and c. b - ma = c
Help please!!! I messed up on the first question I asked, but this one is right!
Answer:
1) m=2/3
2) b=10
3) x-int:(-15, 0)
4) y-int: (0, 10)
Our equation is:
[tex]y=\frac{2}{3}x+10[/tex]
Step-by-step explanation:
To start, let’s find the equation of the line.
We can use the point-slope form:
[tex]y-y_1=m(x-x_1)[/tex]
Where m is the slope and (x₁, y₁) is a point.
So, let’s substitute 2/3 for m and (-3, 8) for (x₁, y₁). This yields:
[tex]y-8=\frac{2}{3}(x-(-3))[/tex]
Simplify:
[tex]y-8=\frac{2}{3}(x+3)[/tex]
Distribute:
[tex]y-8=\frac{2}{3}x+2[/tex]
Add 8 to both sides:
[tex]y=\frac{2}{3}x+10[/tex]
This is in slope intercept form: y=mx+b.
Therefore, our m is 2/3 and our b is 10.
To find the x-intercept, we will substitute 0 for y and solve for x. Therefore:
[tex]0=\frac{2}{3}x+10[/tex]
Subtract 10 from both sides:
[tex]-10=\frac{2}{3}x[/tex]
Multiply both sides by 3/2. So:
[tex]x=-10(\frac{3}{2})=-30/2=-15[/tex]
Therefore, the x-intercept is (-15, 0).
To find the y-intercept, we will substitute 0 for x and solve for y. Therefore:
[tex]y=\frac{2}{3}(0)+10=10[/tex]
So, the y-intercept is (0, 10).
We will also graph it. See the attachment. To graph by hand, we can start at the y-intercept and go up two for every three to the right. Or, we can go down two for every three to the left. This should yield the following graph:

Use y = 16x^2 to complete the table.
What pattern (symmetry) do you notice from the table?
Answer:
In the table, we can see values of x and y, to complete it, we just need to input the different values of x in the equation:
y = 16*x^2
For example in the first slot, we have x = -4
Then we will have:
y = 16*(-4)^2 = 240
Then we complete the empty slot with 240.
The table would be:
[tex]\left[\begin{array}{cccccccccccccccc}x&-4&-3&-2.5&-2&-1.5&-1&-0.5&0&0.5&1&1.5&2&2.5&3&4\\y&240&\end{array}\right][/tex]
Now we just need to do the same for the other values:
y(-3) = 16*(-3)^2 = 144
y(-2.5) = 16*(-2.5)^2 = 100
y(-2) = 16*(-2)^2 = 64
y(-1.5) = 16*(-1.5)^2 = 36
y(-1) = 16*(-1)^2 = 16
y(-0.5) = 16*(-0.5)^2 = 4
y(0) = 16*(0)^2 = 0
y(0.5) = 16*(0.5)^2 = 4
y(1) = 16*(1)^2 = 16
y(1.5) = 16*(1.5)^2 = 36
y(2) = 16*(2)^2 = 64
y(2.5) = 16*(2.5)^2 = 100
y(3) = 16*(3)^2 = 144
y(4) = 16*(4)^2 = 240
Then the complete table is:
[tex]\left[\begin{array}{cccccccccccccccc}x&-4&-3&-2.5&-2&-1.5&-1&-0.5&0&0.5&1&1.5&2&2.5&3&4\\y&240&144&100&64&36&16&4&0&4&16&36&64&10&144&240\end{array}\right][/tex]
Then we can see that there is a symmetry around the value x = 0.

What number is 3/5 more than 0.65?
A) 3/7
B) 13/20
C) 1 1/4
D) 1 2/5
Answer:
Choice C, 1 1/4
Step-by-step explanation:
There are two ways you can go about this problem.
1. Convert 0.65 into a fraction. This will give us 13/20 when simplified.
2. You can add this to 3/5 by getting a common denominator. In this case, 12/20.
3. Add 13/20 and 12/20 to get 25/20.
4. Take the 20 out of the numerator to get 1 5/20 (Hopefully that made sense, if not let me know). Reduce the 5/20 to 1/4.
5. This gives us an answer of 1 1/4.
The other way:
1. Convert 3/5 to a decimal. This gives us 0.6.
2. Add it to 0.65, giving us 1.25
3. Convert 1.25 into a fraction, which is 1 1/4
Hope this helped!
