Answer:
In a collision between two objects, both objects experience forces that are equal in magnitude and opposite in direction. Thus, if the colliding objects have unequal mass, they will have unequal accelerations as a result of the contact force that results during the collision.

Jenny solved the equation 1 – (2x + 4) = –4x + 5. Her work is shown. 1 − ( 2 x + 4 ) = − 4 x + 5 Line 1: 1 − 2 x + 4 = − 4 x + 5 Line 2: 5 − 2 x = − 4 x + 5 Line 3: 2 x = 0 Line 4: x = 0 What is the correct solution to the equation 1 – (2x + 4) = –4x + 5? Re-solve the equation to find the correct solution.
Answer:
4Step-by-step explanation:
Given the equation 1 – (2x + 4) = –4x + 5, we are to find the correct solution of the equation;
Step 1: Open the parenthesis;
1 – (2x + 4) = –4x + 5
1-2x-4 = -4x + 5
1-4-2x = -4x +5
-3-2x = -4x + 5
Step 2: Collect like terms
-2x + 4x = 5 + 3
2x = 8
Step 3: divide both sides by 2;
2x/2 = 8/2
x = 4
Hence the correct value of x is 4
HEY CAN ANYONE PLS ANSWER DIS MATH QUESTION!!!
Answer:
83 and 98
Step-by-step explanation:
The denominator of a certain fraction is 6 more that the numerator,and the fraction is equivalent to 1/3. Find the numerator.
Answer:
Numerator = 3
Step-by-step explanation:
Let the numerator is x.
The denominator is 6 more that the numerator, 6+x
The fraction is equivalent to 1/3. ATQ,
[tex]\dfrac{x}{x+6}=\dfrac{1}{3}[/tex]
Cross multiplying both sides,
[tex]3x=x+6\\\\3x-x=6\\\\2x=6\\\\x=\dfrac{6}{2}\\\\x=3[/tex]
Numerator = 3
So, the numerator is 3.

Answer:
1.2 sq in.
Step-by-step explanation:
We know the formula to find the area of a trapezoid is a+b/2(h)
4+8/2(5)=12/10
12/10=1.2
Therefore the area is 1.2 sq in.
whats the equation for a line thats perpendicular to 6x-2y=8 when it passes through (6,-5)
( i hope i wrote that right sorry)
Answer:
Equation of required line is: [tex]\mathbf{x+3y=-9 }[/tex]
Step-by-step explanation:
We need to find equation for a line that's perpendicular to [tex]6x-2y=8[/tex] when it passes through (6,-5)
We will use the slope-intercept form: [tex]y=mx+b[/tex] where m is slope and b is y-intercept.
Finding Slope m:
When two lines are perpendicular there slopes are [tex]m=-\frac{1}{m}[/tex]
Finding slope of given equation first: [tex]6x-2y=8[/tex]
Writing in slope-intercept form:
[tex]6x-2y=8\\-2y=-6x+8\\y=\frac{-6x}{-2}+\frac{8}{-2}\\y=3x-4[/tex]
Comparing it with slope intercept form: [tex]y=mx+b[/tex] , m= 3
So, slope of given equation is 3
Now, the slope of required equation will be [tex]m=-\frac{1}{m}[/tex]
So, Slope m=-1/3
Finding y-intercept
Using slope m=-1/3 and point (6,-5) we can find y-intercept
[tex]y=mx+b\\-5=\frac{-1}{3}(6)+b\\-5=-2+b\\b=-5+2\\b=-3[/tex]
So, y-intercept is b=-3
Now, finding the equation of required line having Slope m=-1/3 and y-intercept b= -3
[tex]y=mx+b\\y=-\frac{1}{3}x-3[/tex]
Writing in standard form:
[tex]y=-\frac{1}{3}x-3\\y=\frac{-x-9}{3}\\3y=-x-9\\x+3y=-9[/tex]
So, equation of required line is: [tex]\mathbf{x+3y=-9 }[/tex]
Andy runs 436.8 meters in 62.08 seconds. If Andy runs at a constant speed, how can we find out how far he runs in each second? Explain what is happening mathematically to the decimal points in the divisor and dividend before dividing. Do not solve, just explain how you would begin to set up your problem. *
Answer:
7 meters per second.
Step-by-step explanation:
Given that,
Andy runs 436.8 meters in 62.08 seconds.
We need to find how far he run in each second. It can be calculated by dividing distance by time taken as follows :
[tex]x=\dfrac{436.8\ m}{62.08\ s}\\\\=7.03\ m/s[/tex]
or
x = 7 m/s
So, Andy will cover 7 meters per second.

Nick wants to purchase a pair of binoculars that is on sale for $155.75. The sales tax rate in his county is 6.5%. Calculate the amount of sales tax Nick will pay on the purchase. Round to the nearest cent if necessary.
Given:
Price of a pair of binoculars = $155.75
Sales tax = 6.5%
To find:
The amount of sales tax Nick will pay on the purchase to the nearest cent.
Solution:
According to the question,
Sales Tax value = 6.5% of Price of a pair of binoculars
[tex]=\dfrac{6.5}{100}\times 155.75[/tex]
[tex]=0.065\times 155.75[/tex]
[tex]=10.12375[/tex]
[tex]\approx 10.12[/tex]
Therefore, the amount of sales tax is $10.12.
The water level in Ricky Lake changes at an average of -716 inch every 3 years. a. Based on the rate above, how much will the water level change after one year? Show your calculations and you can use the vertical number line to help you., using 0 as the original water level.
Answer:
The water level will change at a rate of - 2 7/18 inches per year
Step-by-step explanation:
From the question, we have a change of -7 1/6 inch every 3 years
We now want to calculate the value of the change every year
Mathematically, that will be;
- 7 1/6 divided by 3
= -43/6 divided by 3
= -43/18 = - 2 7/18 inch per year

The two rectangles shown below have the same
perimeter. Write and solve an equation to find the value of x. Then find the measures of the length and width of
Rectangle B. All measurements are in inches.
9514 1404 393
Answer:
x = 3length = 9width = 3Step-by-step explanation:
The sum of length and width is half the perimeter. If the perimeter is the same, so will be the sum of length and width:
7 + 5 = x + (4x -3)
15 = 5x . . . . . . . add 3, simplify
3 = x
The value of x is 3.
The length of Rectangle B is 4(3)-3 = 9 inches.
The width of Rectangle B is 3 inches.
Explain why the sum of the angle measures in any triangle is 180
Answer:
Step-by-step explanation:
Because every triangle that can ever be made has three sides, you can open up the triangle so that it becomes a straight horizontal line. A horizontal line is also 180 degrees which is why this idea works with triangles.
The reason for the sum of the angles in any triangle is 180 is that when we open up the sides of a triangle we get a straight line where the angle of a straight line is 180 degrees.
What is a triangle?It is a two-dimensional figure which has three sides and the sum of the three angles has are equal to 180 degrees.
We have,
The sum of the angle measures in any triangle is 180.
We see that,
In a triangle, there are three sides and three angles.
If we open up the triangle, we see that the three sides of the triangle form a straight line.
The angle of a straight line is 180 degrees.
Thus,
The reason for the sum of the angles in any triangle is 180 is that when we open up the sides of a triangle we get a straight line where the angle of a straight line is 180 degrees.

Given f(x) = -4x2 +13x-2, what is the value of f(-1)?
Answer:
f(- 1) = - 19
Step-by-step explanation:
To evaluate f(- 1) substitute x = - 1 into f(x) , that is
f(- 1) = - 4(- 1)² + 13(- 1) - 2 = - 4(1) - 13 - 2 = - 4 - 13 - 2 = - 19
