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.

Step-by-step explanation:

Answer:

63°

Step-by-step explanation:

opposite angle

63°

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]

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

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.

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:

60

Step-by-step explanation:

Answer: the correct anwser is D square root of 37

Step-by-step explanation:

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

Answer is 4

-y=-4x+8

y=4x-8

Answer:

4/1 or just 4

Step-by-step explanation:

4x - y = 8

subtract 4x from either side

-y = 8 - 4x

divided either side by -1

y = 8 + 4x

M= 4

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.

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."

Answer:

The slope of the line is zero.

Step-by-step explanation:

The slope is zero. This is a perfectly horizontal line passing through y=−3 .

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

Ex: 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)

Ex: 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)

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

Step-by-step explanation:

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
