Answer:
A negative fraction subtracted from another is the same thing as adding the positive complement of that fraction. Make the denominators (the bottom of the fraction) the same, if they are not already. You can only add halves to halves or quarters to quarters or tenths to tenths and so on. Hope this helps!!

What is the slope of this line? Enter your answer as a fraction in the simplest term in the box.
Answer:
-1/1
Step-by-step explanation:
The slope of a line is always the rise over run where rise is up or down(y axis) and the run is side to side(x-axis). Then, if the line is going up, your answer will be negative. So, using the points given, you can tell that the line is moving 2 units down while also moving 2 units to the left. Another way to calculate this is y2-y1 over(/) x2-x1, the y equals your y coordinates, x equals your x coordinants,d the 1 and 2 represent which points. Whichever point you use, you have to use the same coordinants fr the same value. For example, if you took the points (-2,0) and (0,-2) and you used (0,-2) as your second value, you can enter those into the formula.
(-2)-(0) / (0)-(-2) = -2 / 2
the denominater is a possitive two because, when you subtract a negative number, that number becomes positive and you now add it due to the distributive property. 0-(1)(-2) = -2 x -1 = 2

9.8x+17=7.6x-16
??????
Answer:
2.8867
Step-by-step explanation:
9.8x+17=7.6x-16
We move all terms to the left:
9.8x+17-(7.6x-16)=0
We get rid of parentheses
9.8x-7.6x+16+17=0
We add all the numbers together, and all the variables
2.2x+33=0
We move all terms containing x to the left, all other terms to the right
2.2x=-33
x=-33/2.2
x=-2.8867

Jeremy claims that if a linear function has a slope of the same steepness and the same y-intercept as the linear function in the graph, then it must be the same function.
On a coordinate plane, a line goes through points (0, negative 1) and (2, 0).

Given f(x) = 4x − 6 and g(x) = f(2x),
write an equation for g.
g(x) = _______________________
Answer:
1 and 1/3
Step-by-step explanation:
Fx equals 4x-6
Add six to both sides
6 equals 4X
Divide both sides by 4
2/3 equals x
Then GX equals f (2x)
Two times 2/3 is 1 and 1/3
The value of g(x) when f(x) = 4x − 6 and g(x) = f(2x) will be; 1/3
What is a function?Function is a type of relation, or rule, that maps one input to specific single output.
We have been given that f(x) = 4x − 6 and g(x) = f(2x), then;
We have to Add six to both sides;
f(x) = 4x − 6
6 = 4X
Now Divide both sides by 4;
2/3 = x
Then G(X ) is equals to f (2x)
Now, 2( 2/3 ) = 1 /3
The value of g(x) when f(x) = 4x − 6 and g(x) = f(2x) will be; 1/3

What is a unit rate?It is the quantity of an amount of something at a rate of one of another quantity.
In 2 hours, a man can walk for 6 miles
In 1 hour, a man will walk for 3 miles.
We have,
To find out how many pages each person reads in one hour, we can use the unit rate, the number of pages read per hour.
Jeff read 10(3/4) pages in 1/2 hour.
To find out how many pages he would read in one hour, we can multiply the number of pages he read by the fraction 2/1, which gives:
= 10(3/4) x 2/1
= 21 pages per hour
Jeff read 21 pages in one hour.
Kaley read 12(1/4) pages in 1/3 hour.
To find out how many pages she would read in one hour, we can multiply the number of pages she read by the fraction 3/1, which gives:
= 12(1/4) x 3/1
= 37 pages per hour
Kaley read 37 pages in one hour.
Nikkia read 13(1/2) pages in 3/5 hours.
To find out how many pages she would read in one hour, we can multiply the number of pages she read by the fraction 5/3, which gives:

= 22 pages per hour
Nikkia read 22 pages in one hour.
Thus,

Tucker was asked to solve the equation 5x + 3 = 6x + 1. He did not know if his first step should be to add 5 negative x-tiles, or 1 negative unit tile, to both sides. What advice would you give Tucker to help him decide on his first step? Explain.
Answer: First Subtract 5x from both sides. Then subtract 1 from both sides.
Step-by-step explanation: To solve an equation, get all the variables (x, in this example) on one side and all the constants (numbers alone) on the other side of the equation.
The thing to remember about solving an equation is to keep it balanced. Do the same thing on both sides.
When possible, subtract smaller numbers from higher numbers.
5x + 3 = 6x + 1
5x -5x + 3= 6x - 5x + 1
5x-5x =0 on the left side so they "cancel" On the right, 6x-5x = x
3 = x + 1
3 -1 = x +1 -1
On the right 1-1 = 0 So the 1's "cancel" On the left 3-1 = 2
2 = x Rewrite as x = 2 to tell the solution
A tropical species of mite named Archegozetes longisetosus is the record holder for the strongest insect in the world. It can lift up to 1.182 × 103 times its own weight. If a person who weighed 100 pounds were as strong as this insect, how much could that person lift? Enter the answer using scientific notation.
Answer:
The first thing we have to do is to measure your weight using a weighing scale.
Suppose your weight is 130 pounds, therefore you can lift:
130 pounds * 1.182 • 10^3 = = 153,660 pounds or 1.537 x 10^5 pounds
