Which expression could be used to represent a 45% increase? (Question 9)
Answer:
Options (A) and (B)
Step-by-step explanation:
Question (9)
Let a number = x
45% increase in the given number will be = x + (45% of x)
= x + [tex]\frac{45x}{100}[/tex]
= x + 0.45x
= x(1 + 0.45)
= 1.45x
Therefore, there will be the two expressions,
A). 1.45x
B). x + 0.45x
Options (A) and (B) will be the correct options.
What is the relationship between Za and Zb?
Answer: B
Step-by-step explanation:
∠a and ∠b are complementary angles. Complementary angles are two angles adjacent to each other that add up to 90°. We know this is true because of the 90° angle that is labelled.
Vertical angles are not adjacent to each other. They are across from each other, connected by the angle. They are equal in angles. It is clear that ∠a and ∠b are not equal in angles. Therefore, they are complementary angles.

Does anyone know the formula needed to solve this? Thank you
Did I do this right?
Answer:
no i dont think so
Step-by-step explanation:
1) multiply both sides by p
5/9=-10p
2) divide by -10 to get p
5/9 divided by -10/1
(keep, change flip)
5/9* -1/10
-5/90
therefore p=-5/90
Answer:
No, the answer is -18
Step-by-step explanation:
[tex]\frac{5}{9}[/tex]p = -10
[tex]\frac{5p}{9}[/tex] = -10 CROSS MULTIPLY
-90=5p DIVIDE BOTH SIDES BY 5
-18 = p

3. Gecko Wireless has a 1000 minute monthly plan
that costs $29.95. Each bill also includes $2.95 for
federal communications tax and $0.05 per minute
over 1000. If m represent the minutes over 1000,
which equation represents the cost, p, of wireless
phone service? (MAFS.912.A-CED. 1.1)
defin
solut
a. P= 29.95 + 2.95
b. P=0.05 + m(29.95 +2.95)
P= 29.95 + 0.05m +2.95
d. P= (29.95 + 0.05)m +2.95. What equation should I use?
Answer:
[tex]P=29.95+0.05m+2.95[/tex]
Step-by-step explanation:
The monthly plan costs starts at $29.95, so we're not changing that.
For each monthly plan, we have to pay a tax of $2.95, so we're not changing that.
If we go over 1,000 minutes, we have to pay $0.05 for every minute we go over, and with the fact that [tex]m[/tex] represents each minute over 1,000, we're going to have to represent minutes over 1,000 as [tex]0.05m[/tex] in our equation.
Set up your equation:
[tex]P=29.95+0.05m+2.95[/tex]

Simplify 12edf – 13def. State a property that you can use.
Answer:
-def. In multiplication, the order doesn't matter.
Step-by-step explanation:
A crucial property you can use to simplify this is the fact that, in multiplication, order doesn't matter.
3 * 2 = 6
2 * 3 = 6
5 * 2 * 3 = 30
2 * 3 * 5 = 30
3 * 2 * 5 = 30
Thus,
edf, or
e * d * f
is the same as def,
d * e * f
e * d * f = d * e * f
edf = def
Thus, 12edf is the same as 12def. We can put this in our expression:
12edf - 13def
12def - 13def
Now, we can see that this will equal -1def or -def
12def - 13def
-1def
-def
Answer: -def. In multiplication, the order doesn't matter.

A sequence is defined by the formula f(n+1)=f(n)−3. If f(4)=22, what is f(1)? 10 13 31 34
Answer:
C:31
Step-by-step explanation:
Considering the given recursive function, it is found that the value of f(1) is of f(1) = 31.
What is the definition of the recursive function?It is given by:
f(n + 1) = f(n) - 3.
Which means that each term is the previous term subtracted by 3, hence:
f(4) = 22, f(3) = 25, f(2) = 28, f(1) = 31.

The midpoint of AB is M(2, -1). If the coordinates of A are (1,6), what are the
coordinates of B?
Answer:
work is attached and shown
The coordinate of point B will be (3, -8) for the given line segment.
What are coordinates?A pair of numbers that employ the horizontal and vertical distinctions from the two reference axes to represent a point's placement on a coordinate plane. typically expressed by the x-value and y-value pairs (x,y).
Coordinates are always written in the form of small brackets the first term will be x and the second term will be y.
For example (5,3) here 5 will be for the x and 3 will be for the y.
Another example is (9,0) here 9 is for x and 0 is for y.
Given the line segment, AB
If the M(2, -1) is the midpoint of A(1,6) and B(x,y)
Then,
(1 + x)/2 = 2 ⇒ x = 3
(6 + y)/2 = -1 ⇒ y = -8
So B(3, -8).
Hence "The coordinate of point B will be (3, -8) for the given line segment".

The number line that shows the points −12/5 and –2.8 is Option A.
What is a number line?Integers are arranged at equal intervals along horizontal straight lines called number lines. A number line can be used to represent every number in a series. The endpoints of this line go on forever. Some will have a defined beginning and end. It refers to those as closed number lines. Number lines might be alternatively left empty or blank. A number ladder is a vertical number line.
The given numbers are: −12/5 and –2.8
As we can re-write -12/5 in decimal form= -2.4
Now, we need to mark the number on the number line.
As the number -2.4 lies between -2 and -3 on the left side of zero.
and, -2.4 lies between -the numbers 2.5 and -3.0 on the left side of zero.

Evaluate the function f(x)=6x+2 at the given values of the independent variable and simplify.
a. f(8) b. f(x+6) c. f(−x)
. f(8)= (Simplify your answer.)
[tex]f(x) = 6x+2[/tex]
A.
To evaluate f(8), we substitute x with 8 in our expression.
[tex]f(8) = 6*8 + 2\\f(8) = 48 +2\\f(8) = 50[/tex]
Answer: f(8) = 50
B.
To evaluate f(x+6), we do the same but substitute x with x+6 instead.
[tex]f(x+6) = 6(x+6) + 2[/tex]
Expand the parenthesis by multiplying 6 with x and 6.
[tex]f(x+6) = 6x + 6*6 + 2\\f(x+6) = 6x+36+2\\f(x+6) = 6x+38[/tex]
Answer: f(x+6) = 6x + 38
C.
Again, we're doing the same thing, just substituting x with -x.
[tex]f(-x) = 6 * (-x) + 2\\ f(-x)=-6x+2[/tex]
Answer: f(-x) = -6x+2
Answer:
_____________________________________________

Answer:
1/2x=40
Step-by-step explanation:
3(x - 1) - 8 = 4(1+x) + 5
Answer:
x= 20
Step-by-step explanation:
Step 1- Distribute into the parenthesis.
3x-1(3)-8= 1(4)+4x+5
Step 2- Multiply
3x-3-8= 4+4x+5
Step 3- Add.
3x-3-8= 4x+9
Step 4- Subtract 3x to both sides to move the variable to one side.
3x-11= 4x+9
-3x -3x
Step 5- Subtract 9 to both sides.
-11= 1x+9
-9 -9
-20= x
Exchange the signs.
20= x
Answer:
x = -20
Step-by-step explanation:
3(x - 1) - 8 = 4(1+x) + 5
3x - 3 -8 = 4 + 4x + 5
3x - 11 = 9 + 4x
-x = 20
