A line going through the points (-3, -10) with a slope m = 1/4.
Step-by-step explanation:
(-3,5) and (x,y)
Slope = (y - 5)/[x - (-3)] = (y - 5)/(x + 3)
(y - 5)/(x + 3) = -1/4
y - 5 = -1/4(x + 3)
y - 5 = (-1/4)x - 3/4
y = (-1/4)x - 3/4 + 5
y = (-1/4)x + 17/4.
Put the following equation of a line into slope-intercept form, simplifying all fractions. 2x-10y=-20.
As a result, the slope is 1/5 and the y-intercept is 2, and the equation is written in slope-intercept form as y = (1/5)x + 2.
what is slope intercept ?On a two-dimensional coordinate plane, the equation of a line is shown using the slope-intercept form. Y = mx + b, where m is the line's slope and b is the y-intercept, is how the equation is expressed. The pace at which the line is rising or dropping is indicated by the slope (m). It is the ratio of any two places on the line's vertical change (rise) to horizontal change (run). In other words, it informs you of the line's steepness. The line is rising from left to right if the slope is positive, and descending from left to right if the slope is negative.
given
We must find y in order to convert the equation 2x - 10y = -20 into slope-intercept form, which is represented by the formula y = mx + b, where m is the slope and b is the y-intercept.
2x - 10y = -20
Initially, we must separate the y term from the other terms by deducting 2x from both sides:
-10y = -2x - 20
The next step is to separate y by multiplying both sides by -10:
y = (2/10)x + 2
When we simplify the fraction, we obtain:
y = (1/5)x + 2
As a result, the slope is 1/5 and the y-intercept is 2, and the equation is written in slope-intercept form as y = (1/5)x + 2.

Two cars leave a rest stop at the same time and proceed to travel down the highway in the same direction. One travels at an average rate of 49 miles per hour, and the
other at an average rate of 68 miles per hour. How far apart are the two cars after 4.5 hours?
Answer:
The answer is going to be 85.5 miles apart.
Step-by-step explanation:
if the first car is going 49 miles for every hour and the second at 68 we now have our two numbers. then we know its 4.5 hours so our equation goes like this.
(68*4.5)-(49*4.5)=y
We do our rules with pemdas and what not.
we get
306-220.5=y
We subtract and bam
y= 85.5 miles apart.

Answer:
3.5 Hours

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.

A seesaw is 3 metres long. It is balanced when child A sits 0.8 m from the pivot and child B sits 0.6 m from the pivot. Child A has a weight of 300 N. i. Draw a force diagram to represent this system. (Ensure that you label the force and distances given.) ii. Use the principle of moments to determine the weight of child B.
Answer:
i) see attached diagram
ii) 400 N
Step-by-step explanation:
Since we don’t know the mass of the seesaw, take moments about M (so we don’t have to consider R or mg).
Moment = Force x Perpendicular Distance to the Pivot
As the system is in equilibrium, total anti-clockwise moment = total clockwise moment:
⇒ 300 × 0.8 = b × 0.6
⇒ 0.6 b = 240
⇒ b = 400 N

find the value of x

Answer:
x must be 4
Step-by-step explanation:
Write and solve an equation of ratios. Start with the ratio of the hypotenuses:
x + 2 x
----------- = --------
x + 5 x + 2
Cross multiplying results in (x + 2)^2 = x^2 + 5x
performing the indicated squaring, (x + 2)^2 = x^2 + 4x + 4. And therefore:
x^2 + 4x + 4 = x^2 + 5x
Simplifying, we get 4x + 4 = 5x, so x must be 4
