Find the slope and y-intercept
and write the equation.
(-98, 22), (0, -48)
m =
b=
Answer:
m = -35/49
c = -48
y = -35/49 x - 48
Step-by-step explanation:
Given the coordinate point
(-98, 22), (0, -48)
Slope m = y2-y1/x2-x1
m = -48 - 22/0 -(-98)
m = -70/98
m = -35/49
Substitute m = -35/49 and (0, -48) into the equation y = mx+c
-48 = 0(-35/49) + c
-48 = c
c = -48
Hence the y-intercept is -48
Get the equation
Recall that y = mx+c
y = -35/49 x - 48

Answer:
m=9 cm; n=4 cm
Step-by-step explanation:
The area of the rectangle is m*n, and the area of the square is 6*6. We are told that the areas of the rectangle and square equal each other, so:
[tex]m*n=36[/tex]
We are told that m is 5 cm longer than n, so we know that:
[tex]m = 5+n[/tex]
Therefore, we can solve for n using substitution.
[tex]m*n=36\\(5+n)n = 36\\5n+n^2 = 36\\n^2 + 5n -36 = 0\\(n+9)(n-4)=0[/tex]
We now have two answers for n: -9 and 4. However, the side length cannot be negative; that simply wouldn't make any sense. Therefore, n = 4.
Next, using the same equation, plug in 4 for n and solve for m.
[tex]m*n=36\\m*4=36\\m=9[/tex]

solve for the missing side: simplify the radical
Answer:
[tex]x=8\sqrt{5}[/tex]
Step-by-step explanation:
I will assume the following:
You know how to use the quadratic formulaYou know how to simplify radicalsYou know how to use the pythagorean theorem.The challenge of this exercise comes from using the pythagorean theorem and setting up a few equations.
Given that we have a segment 36 units long and another segment that is 16, it is trivial to get the other segment, 20. Additionally, there are two sides that I want to name so that way I can make a couple of substitutions. I will call these side a and side b. (see attachment 1)
Now comes with setting up three equations. I will start with the two smaller triangles, using side a and side b. See attachments 2 and 3.
Now with the big triangle. I will set up one last equation. See attachment 4.
Given what we know about attachment 2 and 3, we can make two substitutions. See attachment 5. I assume you know how to do the rest and arrive at your only real solution.

A bus increases its position at a constant velocity for 12 s, and then it stops for 6 s.
Which option lists a true statement about how a distance-time graph would represent this motion?
A) The slope of the graph would be negative and constant for 12 s; then, the slope would be constant for 6 s because the slope represents velocity.
B) The slope of the graph would be positive and constant for 12 s; then, the slope would be 0 for 6 s because the slope represents velocity.
C) The slope of the graph would be positive and increasing for 12 s; then, the slope would be constant for 6 s because the slope represents velocity.
D) The slope of the graph would be negative and constant for 12 s; then, the slope would be 0 for 6 s because the slope represents the passing of time.
Answer:
D
Step-by-step explanation:
The slope of the graph would be negative and constant for 12 s; then, the slope would be 0 for 6 s because the slope represents the passing of time. Therefore, option D is the correct answer.
What is a constant velocity?Velocity gives us information about the rate of change of your position, meaning how fast your position is changing per unit time.
Given that, a bus increases its position at a constant velocity for 12 s, and then it stops for 6 s.
Here, rate of change is 12/6 = 2 s
Therefore, option D is the correct answer.

Answer:
n^2(radical)7
Step-by-step explanation:
You have to find the square root of all the components separately. 7 is not a perfect square (one number*itself = perfect square, ex 4 is the perfect square of 2 because 2*2=4) but the n^4 can be simplified and brought outside of the radical. When finding the square root of variables with exponents they have to come out in pairs to create that "perfect square." Therefore when you move a variable, you basically divide the exponent by 2. so n^4 inside the radical becomes n^2 outside of the radical, leaving the problem itself to become n^2 (radical) 7.

Answer:

Step-by-step explanation:
-3s(s - 10) + 7(-2s -1) --> (-3s^2+30s)+(-14s-7) ---> -3s^2+16s-7
DO multiplication them convert like terms
Answer:
-3s² + 16s - 7
Step-by-step explanation:
Remember to follow FOIL. FOIL stands for (First, Outside, Inside, Last).
First, distribute -3s to s and -10, and 7 to -2s and -1:
-3s(s - 10) = -3s² + 30s
7(-2s - 1) = -14s - 7
Next, combine like terms:
-3s² + 30s - 14s - 7
-3s² + (30s - 14s) - 7
-3s² + 16s - 7
-3s² + 16s - 7 is your answer.

A group of students are going on a trip and the trip costs $36.50 per student which includes $9.50 for lunch, an entrance ticket and a gift coupon. The gift coupon costs $50 for the entrance ticket. The cost of an entrance ticket is
A) $27.00
B) $25.00
C) $18.00
D) $13.50
Answer:
The answer is D) $13.50
Step-by-step explanation:
So first what you're gonna do it subtract $9.50 from $36.50 which will get you to $27.00.
Then you'll have to figure out what half of $27.00 is.
That will get you to the answer of D) $13.50
Which value of x makes the equation 0.75(x + 20) = 2 + 0.5(x - 2) true?
A. -64
B.64
C. 56
D.-56
The value of x for which equation 0.75(x + 20) = 2 + 0.5(x - 2) becomes true is equal to -56.
An equation is given which is 0.75(x + 20) = 2 + 0.5(x - 2).
We have to find out the value of x for which the equation becomes true.
What do you mean by algebraic expressions ?
The algebraic expressions are those which are made up of variables, constants and algebraic operations i.e., addition, subtraction, etc.
As per the question ;
The equation given is 0.75(x + 20) = 2 + 0.5(x - 2)
Let's solve to get the value of x.
⇒ 0.75(x + 20) = 2 + 0.5(x - 2)
⇒ 0.75x + 15 = 2 + 0.5 x - 1
⇒ 0.75x - 0.5x = 1 - 15
⇒ 0.25x = - 14
⇒ x = -14 ÷ 0.25
⇒ x = - 56
Let's check ;
0.75(x + 20) = 2 + 0.5(x - 2)
0.75 ( -56 + 20 ) = 2 + 0.5 ( -56 - 2 )
(0.75 × -56) + (0.75 × 20) = 2 + (0.5 × -56) + (0.5 × -2)
-42 + 15 = 2 -28 - 1
-27 = -27
Both sides are equal for value of x = -56.
Thus , the value of x for which equation 0.75(x + 20) = 2 + 0.5(x - 2) becomes true is equal to -56.
