Step-by-step explanation:
Answer:
Since we get '2' as an output when we input '0'
So, the function must be increasing the value of x by 2
We see that happen in the second case as well, as our input is incremented by 2
Hence, we can say that
f(x) = x + 2

(6 + 4)^2 + (11+ 10/2) Simplifyyyyy
Answer:
116
Step-by-step explanation:
we do pemdas so start with parenthesis
6+4=10
10 squared =100
then we divide before adding so
10/2 = 5+11= 16
100+16= 116
Ericka is also in Mr. Whittaker’s science class and she recorded the variation in water level at a different part of the river. She observed that the water level there fell 2.2 millimeters per year over a period of 6.2 years This data is compared to the average annual trend, which shows the water level rising 1.8 mm/year. Which of the decimals in the problem should be represented as a negative rate? Which two factors should Ericka multiply to find the total variation in water level?
Answer:
first one is 2.2mm/year and second is 6.2years and -2.2mm/year
Step-by-step explanation:
plz trust me i just did it
The decimals in the problem should be represented as a negative rate is -2.2mm/year
What is the rate of change?It is defined as the change in values of a dependent variable with respect to the independent variables.
It is given that:

Bill Granger is a parts clerk. He worked a total of 46.25 hours from Monday to Friday this week. If his regular pay is $12.75 per hour, how much overtime pay did Bill earn?
Answer:
His extra pay would be of $79.69
Step-by-step explanation:
Assuming that the clerk works regular 40 hour per week, then he has worked 6.25 extra (overtime) hours this week. Then his extra pay for overtime work would be:
6.25 times $12.75 = $79.69

what is
2/3 of 1/4 of x = 1360
Answer:
[tex] \boxed{ \bold{ \huge{ \boxed{ \sf{x = 8160}}}}}[/tex]
Step-by-step explanation:
[tex] \sf{ \frac{2}{3} \times \frac{1}{4} \times x = 1360}[/tex]
To multiply one fraction by another, multiply the numerators for the numerator and multiply the denominators for its denominator and reduce the fraction obtained after multiplication into lowest term
[tex] \longrightarrow{ \sf{ \frac{2 \times 1}{3 \times 4} \times x = 1360}}[/tex]
[tex] \longrightarrow{ \sf{ \frac{2}{12} \times x = 1360}}[/tex]
[tex] \longrightarrow{ \sf{ \frac{1}{6} x = 1360}}[/tex]
Solve for x
[tex] \longrightarrow{ \sf{x = 1360 \times 6}}[/tex]
[tex] \longrightarrow{ \sf{x = 8160}}[/tex]

To get ready for a field trip, students and adults were put into groups. For every 8 students in a group, there were 3 adults. In total, in all the groups, there were 48 students. How many adults were also on the field trip?
Answer:
18!
Step-by-step explanation:
Divide the number of students (48) by 8 to find the number of groups and get 6 if there are 6 groups of 8 and 3 adults with every 8 students then multiply 6 by 3 and receive an 18!!
Hope this helped! Let me know if you are confused at all!
Which absolute value function opens down?
1)y = 2|x- 5|
2)y = [X + 1|-7
3)y = -|X+ 4 |+ 8
4)y = 1/4|X-9|
Answer:
3) y = - | x + 4| + 8Step-by-step explanation:
The general form of an absolute value function is
f(x)=a|x-h|+kIt opens up if a> o and opens down if a < 0
From the given functions:
y = - | x + 4| + 8, opens downsee attached for reference

All three sides of a triangle are initially 4 m in length. One of the triangle's sides is oriented horizontally. The triangle is scaled down in size without changing any of the angles. What is the new height of the triangle when the area is exactly half of the original triangle's area
Answer:
the new height of the triangle = 2.449
Step-by-step explanation:
Given that:
the sides of the triangle are 4m in length i.e they are equal. It shows that the triangle is known to be an equilateral triangle.
Let say the triangle is a triangle IJK
Let the length of the side to be i = 4
Definitely
IJ = JK = IK = i = 4
If a midline is drawn and cuts the equilateral triangle in two equal halves of a right-angle triangle. Then, suppose the midline is L
Then ;
[tex]JL = \dfrac{1}{2} JK[/tex]
[tex]JL = \dfrac{1}{2} i[/tex]
Let consider triangle IJL
(IL)² = (IJ)² - (JL)²
[tex](IL)^2 = i^2 - \dfrac{i^2}{4}[/tex]
[tex](IL)^2 = \dfrac{3i^2}{4}[/tex]
[tex](IL) =\sqrt{ \dfrac{3i^2}{4}}[/tex]
[tex]IL =\sqrt{3} \dfrac{i}{2}[/tex]
Area of triangle IJK can be expressed as:
[tex]Area = \dfrac{1}{2}\times Base \times Height[/tex]
[tex]Area = \dfrac{1}{2}\times i \times \sqrt{3}\dfrac{i}{2}[/tex]
[tex]Area = \sqrt{3}\dfrac{i^2}{4}[/tex]
where, i = 4
Then:
[tex]Area = \sqrt{3}\dfrac{4^2}{4}[/tex]
[tex]Area = \sqrt{3} \dfrac{16}{4}[/tex]
[tex]Area =4 \sqrt{3}[/tex]
when the area is exactly half of the original triangle's area, the new height is :
[tex]A = \dfrac{1}{2} \times Area[/tex]
[tex]\sqrt{3} \dfrac{i^2}{4} = \dfrac{1}{2} \times 4\sqrt{3}[/tex]
[tex]\dfrac{i^2}{4} = \dfrac{1}{2} \times 4[/tex]
[tex]\dfrac{i^2}{4} =2[/tex]
[tex]i^2 = 8[/tex]
[tex]i= \sqrt{8}[/tex]
[tex]i= \sqrt{4 \times 2}[/tex]
[tex]i= 2 \sqrt{2}[/tex]
Finally, the new height of the new triangle is:
[tex]IL =\sqrt{3} \dfrac{i}{2}[/tex]
[tex]IL =\sqrt{3} \dfrac{2 \sqrt{2}}{2}[/tex]
[tex]IL =\sqrt{3 \times 2}[/tex]
[tex]IL =\sqrt{6}[/tex]
IL = 2.449 m

Answer:
LOM= 130º
Step-by-step explanation:
Combine the two equations and set it to equal 180º(LON), 180º=12x+120º
next subtract 120º from both sides, 60º=12x. Now divide both sides by 12, 5=x. Now you can plug 5 back into the original equation to calculate MON, 8x5+90º
Answer:
∠MON = 130
Step-by-step explanation:
∠LON = 180°
∠LOM + ∠MON = 180 -------equation
where:
∠LOM = 4x + 30
∠MON = 8x + 90
plugin values into the equation
4x + 30 + 8x + 90 = 180
4x + 8x + 30 + 90 = 180
12x = 180 - 30 - 90
12x = 60
x = 60/12
x = 5
plugin values to ∠MON = 8x + 90
∠MON = 8x + 90
∠MON = 8(5) + 90
∠MON = 130

Ashley can ride her bicycle 15 miles
If your question is: Ashley can ride her bicycle 15 miles in 2 hours. There are 60 miniutes in an hour and there are 1760 yards in 1 mile. How many yards does Ashley travel each minute?
____________________________________
First, do 15 miles divided by 2 hours. In addition, do 1 hour divided by 60 minutes (1). Thus, do 1760 yards divided by 1 mile. Therefore, you can multiply these together to get 220 yards/min.
Best of luck!

Solve for x: x − 2 > 2x + 12
Answer:
x < -14
Step-by-step explanation:
Solve the inequality x − 2 > 2x + 12 for x:
First, subtract x from both sides. In the resulting inequality x is on the right side with +12:
-2 > x + 12
Subtract 12 from both sides to isolate x:
-14 > x OR x < -14

2 is a solution for
True or False
Answer:
False
Step-by-step explanation:
The open circle means you should not include the number it is on.
The inequality would look like, x<2 and not equal to. Therefore, 2 is not a solution.
Answer:
False
Step-by-step explanation:
When there is an open circle, it means that it can't be that exact number. If there is a closed circle, it can be that number. This is an open circle, and means that it is less than 2.

What is the vertex of the parabola in the graph?
Answer:
Parabolas always have a lowest point (or a highest point, if the parabola is upside-down). This point, where the parabola changes direction, is called the "vertex". If the quadratic is written in the form y = a(x – h)2 + k, then the vertex is the point (h, k).

Answer:
g= −6/13o5
Step-by-step explanation:
Let's solve for g.
−3−(−8)−(−2)=x0−13ogo3o
Step 1: Flip the equation.
−13go5+1=7
Step 2: Add -1 to both sides.
−13go5+1+−1=7+−1
−13go5=6
Step 3: Divide both sides by -13o^5.
−13go5
−13o5
=6−13o5
g=−6/13o5
