What is an equation?A mathematical statement that has a "equal to" symbol between two expressions with equal values is called an equation. as in 3x + 5 = 15, for instance. There are different types of equations like linear, quadratic, cubic, etc.
t d
1 195
2 130
2.5 97.5
The distance will be calculated by the equation of the line,
y = mx + c
m = ( 130 - 195 ) / ( 2 - 1 )
m = -65
y = -65x + c
195 = -65 + c
c = 260miles
Hence, the distance will be 260 miles.

PLEASE HELP ASAP I WILL GIVE BRAINSLET TO THE CORRECT ANSWER!!!!!!!!!!
I THINK!!!!!! (x, y) = (-4, -25) im not completely sure tho
Step-by-step explanation:
substitute y = 7x + 3 in equation 2
9x - 2y = 14
9x - 2(7x + 3) = 14
9x - 14x + 6 = 14
-5x + 6 = 14
-5x = 14 - 6
x = 8 ÷ 5
x = 1.6
subs x = 1.6 into equation 1
y = 7x + 3
y = 7(1.6) + 3
y = 11.2 + 3
y = 14.2
thus, x = 1.6, y = 14.2

Which is an x-intercept of the continuous function in the
table?
0
1
2
3
-2
(0,-6)
(3,0)
(-6,0)
(0,3)
Answer:
-6
Step-by-step explanation:
x-intercept is y = 0, so the point is (-6, 0), answer is -6
The Points (-1, 0), (2, 0) and (3, 0) are the x-intercepts of the function f(x).
What is Intercept?The term "intercept" refers to the location where a line or curve crosses a graph's axis. The x-intercept is the point at which the x-axis is crossed. The y-intercept is the point at which the y-axis is crossed.
The x- or y-axis intersection point is what is meant when a line has an intercept. The y-axis is often taken into account if the axis is not stated. The letter "b" is typically used to represent it.
We know that the x intercept can be find where the value of y=0
So, From the table attached,
For x = -1, f(-1) = 0
For x = 2, f(2) = 0
For x = 3, f(3) = 0
Thus, Points (-1, 0), (2, 0) and (3, 0) are the x-intercepts of the function f(x).

The perimeter of a rectangle is 52 cm. If its width is 2 cm more than one-third of its length, find the dimensions of rectangle.
(A) 12 cm x 4 cm (B) 18 cm x 8 cm (C) 15 cm x 9 cm
Answer:
(B) 18 cm × 8 cmStep-by-step explanation:
Perimeter of a rectangle = 52 cm
2(length + width) = 52 ==> l + w = 26
Let x be the length
width = (x/3) + 2
x + (x/3) + 2 = 26
[(3x + x)/3] + 2 = 26
4x / 3 = 24
4x = 24 (3)
x = 6(3) ==> 18 cm
Width = (18/3) + 2
= 6 + 2 = 8 cm
So, the required dimension is 18 cm x 8 cm.

B. 18 * 8.Step-by-step explanation:
Let the perimeter be:
52 cm.Find the numbers for the perimeter:
For A:
(12 cm + 4 cm) * 2 = 32.That means A is incorrect.
For B:
(18 + 8) * 2 = 52 cm.That means B is correct.
For C:
(15 + 9) * 2 = 48 cm.That means C is incorrect.
Correct choice is B.

Hi! Let me help you!
Perpendicular lines have slopes that are opposite reciprocals.This means we take a number, flop it over, and change its sign.In this case, we have a line with a slope of [tex]\displaystyle-\frac{1}{3}[/tex]Flop it over:[tex]\rm{-3}[/tex]Change its sign:3Thus, the slope of the line perpendicular to the given line is 3.Now, what is its equation?Since we know the slope and a point that the line intersects, we can write the line's equation in Point-Slope Form:y-y1=m(x-x1)Where y1 is the y-coordinate of the point, m is the slope, and x1 is the x-coordinate.In this case, y1=2, m=3, and x1=4.Plug in the values:y-2=3(x-4)y-2=3x-12y=3x-12+2y=3x-10Answer:

Answer:
Step 1) P = 600, Decimal format: 0.04, Balance = 624
Step 2) Principle = 624, Balance = 648.96
Step 3) Principle = 648.96, Balance = 674.92
Step-by-step explanation:
Use the formula of A = P(1 + r/n)^n*t
P = 600, r = 4%, n = 1, t = 1 years.
Plug in
A = 600(1 + 0.04/1)^1*1
A = 600 * 1.04^1
A = 600 * 1.04
A = 624
To find the seperate interest
A = P + I
624 = 600 + I
I = 624 - 600
I = 24
Repeat for Step 2
P = 624, r = 4%, n = 1, t = 1
A = 624(1 + 0.04/1)^1*1
A = 624 * 1.04^1
A = 624 * 1.04
A = 648.96
Repeat for interest
648.96 = 624 + I
I = 648.96 - 624
I = 24.96
Repeat for step 3
A = 648.96, r = 4%, n = 1, t = 1
A = 648.96(1 + 0.04/1)^1*1
A = 648.96 * 1.04^1
A = 648.96 * 1.04
A = 674.92
Interest repeat
674.92 = 648.96 + I
I = 674.92 - 648.96
I = 25.96
Sarah is planning to take
aerobics classes at a gym.
Non-members pay $8 per
class, while members pay $4
per class and a $20
membership fee. If Sarah
plans to take 6 aerobics
classes, should she become a
member of the gym? Explain
why or why not?
Answer:
Yes
Step-by-step explanation:
Non members - 8*6 = $48
Members - 20+(4*6) = $46
She should become a member of the gym because she will pay $2 less overall.
Answer:
Sarah should become a member. She would be paying a lot less money and be able to take more classes for cheaper
Step-by-step explanation:
Non member amount for 6 classes- $8*6= $48
Member amount for 6 classes- $4*6= 24 ($20 fee) = $44
As you can see above, the cost for 6 classes with a membership is cheaper than without a membership

How can you find the perimeter of the rectangle by only knowing its area
Answer:
It's not possible to determine the perimeter of a rectangle given only the area. The area of a rectangle depends on two unknowns, the length and the width, so you must be given at least one side of the rectangle along with the area to determine the other side and, thus, the perimeter
Step-by-step explanation:

It is not possible to determine the perimeter of a figure given its area.
The 5th grade classes at Brookfield School used 5 identical buses to go on a field trip.
There were a total of 40 seats on each bus.
All of the seats on 4 buses were filled.
The fifth bus had 4/5 of the seats filled.
1/8 of all the passengers on the buses were adults.
How many adults went on the field trip with the 5th grade classes?
1/8 x 5 = 5/8
5/8 of the passengers were adults :)

Find the equation of the line passing through the point (2,-4) that is parallel to the line y=3x+2
Answer:
y=3x-10
Step-by-step explanation:
When you have to find a parallel line, you take the slope of the other line, so we already know y=3x+b. Then, plug in 2 and -4 as your x and y values and you get -4=3(2)+b. Then solve 3×2=6, so -4=6+b, subtract 6 from both sides, -10=b.

A normal distribution (X) has a mean of 100 and a standard deviation of 10.
What is the x value that is the third quartile for this distribution?
Round your answer to the first decimal position.
The x value for the third quartile for this distribution is 106.8
Z score
The z score is used to determine by how many standard deviations the raw score is above or below the mean. It is given by:
z = (x - μ) / σ
where μ is the mean, x = raw score and σ is the standard deviation.
Given μ = 100, σ = 10.
The third quartile correspond with a z score of 0.675, hence:
0.675 = (x - 100) / 10
x = 106.8
The x value for the third quartile for this distribution is 106.8
