<h3>What is a linear equation?</h3>
Linear equation are equation in which the highest power of the variable is equals to 1.
Suzan is saving money to buy a bike . She already have $63 and is going to save an additional $9 per week. The cost of the bike is $198.
Let
w = number of weeks
The linear equation that can be used to represent the situation using 9, w and 163 is as follows:
using the slope-intercept form,
y = mx + b
where
m = slope
b = y-intercept
Therefore,
The solved equation to find the number of weeks is as follows:
- 9w = 198 - 63
- 9w = 135
- w = 135 / 9
- w = 15

Step-by-step explanation:
volume of a cylinder is
ground area × height = pi×r²×h
r = 4
what we need to calculate is how high the water stands with one "serving" of 2m³.
that height is then added every minute (with the additional 2m³ during that minute).
so,
2 = pi×4²×h = pi×16×h
2/16 = 1/8 = pi×h
h = (1/8) / pi = 1/(8pi) = 0.039788736... m
that is rounded about 0.04 m or 4 cm.
therefore, the water rises by 0.04 m or 4 cm per minute
0.04m/min
Answer:
6x + 3
Step-by-step explanation:
Just add the X's (5x + x)=6x, since there is only one whole number without any variables you dont have to do anything to it. So 6x + 3 is your answer.
Answer:
5y = -2x + 31
Step-by-step explanation:
Given equation:
y = 
Coordinate = (-7,9)
Unknown:
Equation of the line perpendicular = ?
Solution:
The slope - intercept format of a line is given as;
y = mx + c
where y and x are the coordinates
m is the slope
c is the y-intercept
y =
From the given equation; slope is 
A line perpendicular will have a slope that is negative and the inverse of this;
slope of perpendicular line = 
Since y= 9 and x = -7;
So;
9 = 
+ C
9 = 
+ C
C = 9 - = 
Now,
y = x +
mulitply through by 5;
5y = -2x + 31
