Which value of x makes the equation
0.25(x + 20) = 0.1(x + 70) + 0.05x true?
A.0.2
B.25
C.20
D.2
Answer:
C. 20
Step-by-step explanation:
20 is the only value that makes x true. Basically x = 20.
We find this by doing the "good ol' Isolate the variable by dividing each side by factors that don't contain the variable."
Hope this helps and have a nice day!

The graph of y = f(-x) is a reflection of the graph of y = f(x) in the x-axis.
The graph of y = -f(x) is a reflection of the graph of y = f(x) in the y-axis.
Answer:
The graph of y = f(-x) is a reflection of the graph of y = f(x) in the x-axis. ⇒ False
The graph of y = -f(x) is a reflection of the graph of y = f(x) in the y-axis. ⇒ False
Step-by-step explanation:
Let us explain the reflection about the axes
If a graph is reflected about the x-axis, then the y-coordinates of all points on it will opposite in signEx: if a point (2, -3) is on the graph of f(x), and f(x) is reflected about the x-axis, then the point will change to (2, 3)
That means reflection about the x-axis change the sign of yy = f(x) → reflection about x-axis → y = -f(x)If a graph is reflected about the y-axis, then the x-coordinates of all points on it will opposite in signEx: if a point (-2, -5) is on the graph of f(x), and f(x) is reflected about the y-axis, then the point will change to (2, -5)
That means reflection about the y-axis change the sign of xy = f(x) → reflection about y-axis → y = f(-x)Now let us answer our question
The graph of y = f(-x) is a reflection of the graph of y = f(x) in the x-axis.
It is False because reflection about x-axis change sign of y
The graph of y = -f(x) is a reflection of the graph of y = f(x) in the x-axis
The graph of y = -f(x) is a reflection of the graph of y = f(x) in the y-axis.
It is False because reflection about y-axis change sign of x
The graph of y = f(-x) is a reflection of the graph of y = f(x) in the y-axis

Tyrell went to the park to go jogging. The beginning of the running path has an elevation of -2 feet. The highest elevation on the jogging path is 14 feet. What is the difference in elevation between the highest point and the beginning of the path? Make sure you write down the highest point first then take away the negative two.
Answer:
16 ft
Step-by-step explanation:
Difference in a math question always signifies that we are subtracting. When finding the difference between an elevation you need to subtract the highest point first from the lowest point or starting point. Therefore in this scenario, we subtract 14 feet which is the highest point from the starting point which is -2 ft. Since the starting point is at a negative elevation, the negatives will cancel out and becomes a positive.
14 - (-2) = x ... negative cancel out and become a positive or addition
14 + 2 = x
16 ft = x
Finally, we can see that the difference between these two points is 16 ft.

write an equation of a line that passes through the point (4,2) with a slope of 1/4
Answer:
Slope Intercept Form: y = [tex]\frac{1}{4}[/tex] x + 1
Point Slope Form: y - 2 = [tex]\frac{1}{4}[/tex] × (x - 4)
Standard Form: 1x - 4y = -4
Step-by-step explanation:
Answer:
[tex]y=\frac{1}{4} x+1[/tex]
Step-by-step explanation:
A linear equation needs two pieces of information: the slope of the line, and its y-intercept. Since we are already given the slope we can plug that into the standard equation format:
y=mx+c, where m=slope and c=y-intercept
y=1/4x+c
Now we just need to find the y-intercept.
To find it we are given a point: (4,2), which we can use to trace back to the y-intercept using the slope. The slope of the line of 1/4. This means that the point before it is located 4 units to the left on the x intercept, and 1 unit lower on the y-intercept. Conveniently, this gives us our y-intercept, as the x values 4-4=0. The y value is 1 (2-1) so our y-intercept is 1!
So now we have our equation:
y=1/4x+1
Hope this helped!
Z1 and z2 are complementary angels given m z1= 12°, find mZ2.
m2
Sum of two angles that are complementary = 90°
m∠1 + m∠2 = 90°
Given :
m∠1 = 12°
Then :-
[tex]12° + ∠2 = 90°[/tex]
[tex]∠2 = 90 - 12[/tex]
[tex]∠2 = 78°[/tex]
∴ m∠2 = 78°Name the plane in 2 ways please! simple and quick :)

Count the number of places it takes to get one place past 3
There are 5 zeros in the given question. That gets you to just before the 3.
Add one more to get past the 3. That makes 5 zeros + 1 more place = 6
Since you are moving right, the 6 is minus. Your answer is 3 * 10^-6
i need help with this geometry
Answer:
2.
Step-by-step explanation:
supplementary= 180 degrees.
Step-by-step Explanation: If two parallel lines are cut by a transversal, then same-side interior angles are supplementary or the sum of their measures is 180 degrees.
Notice that <3 and <5 are same-side interior angles because they lie on
the same side of the transversal and on the interior of lines l and m.
Notice that same-side interior angles make a C shape.
38% of the 1200 Robinson students are 7" graders. How many Robinson
students are 7 graders?
For percentages, we write the number before the % sign as a decimal out of 1. So our percentage would actually be 0.38
To find what percent of Robinson students are 7th graders, we simply multiply 0.38 by 1200 which gives us 456
The answer is 456

Complete question:
Kyle incorrectly says that the product of - ( - 6 ) # ( - 1 ) is 6 . 11. After a recycling awareness program, the number of tons of recyclable material taken to the landfill is reduced by 13 7/10 tons per month. Represent the total change in the tons of recyclable material taken to the landfill after 7 months resulting from the awareness program a. What is the correct product? 10 month. Represent the total change in the b. What was Kyle's likely error?
Answer:
Kindly check explanation
Step-by-step explanation:
Given that :
Kyle incorrectly says that the product of - ( - 6 ) ( - 1 ) is 6
-(-6)(-1) = 6 [incorrect]
Correction:
-(-6) (-1) :
- (-6) = 6
6 (-1) = - 6
Given that reduction in materials = 13 7/10 tons per month
Monthly reduction = 13 7/10 = 137/10 tons
After 7 months : (7 * 137/10) = 959/10 tons = 95.9 tons
Change in amount of material taken to the land fill:
Initial amount - amount after 7 months
If initial amount = x
Change in amonnt = (x - 95.9) tons

Answer:
D. 6 1/12
Step-by-step explanation:
First add the like fractions.
3 2/3 + 2/3 = 3 4/3 (Don't worry about simplifying yet)
Now find the least common multiple for 3 4/3 and 1 3/4 so we can add them.
REMEMBER: You can only add and subtract fractions when they have the same denominator.3: 3, 6, 9, 12
4: 4, 8, 12
In this case 12 is the least common multiple.
3/4 x 3/3 = 9/12 9/12
4/3 x 4/4 = 16/12
Add those two fractions then add the whole numbers and put it in front.
4 25/12
Simplify

Step-by-step explanation:
6+ 12x + 36 = -8.5x - 40 equations with variables
Answer:
x=-4
Step-by-step explanation:
First, you would simplify the like terms on both sides of the equation to get 42 + 12x = -8.5x - 40
Second, you would want to add and subtract terms to get the X's on one side, and the whole numbers on the other.
12x + 8.5x = -40-42
Third, simply the terms.
20.5x=-82
Fourth, divide both sides by 20.5 to get the x on its own, and then you will have your answer of x=4.
