Answer:
We are here given,
4a+23-22 = 32
Solving (23-22):
4a+1 = 32
Now transposing (+1) to RHS:
4a = 32-1
=4a = 31
Now transposing 4 to RHS:
a = 31÷4
= a = 7.75
Thus the value of a is 7.75
Answer:
4^2 / px3 = 2/3
Step-by-step explanation:
4^2 / px3 = 4^2 / 8 *3
= 4*4 / 8*3
= 4/ 2*3
= 2/3
Answer:
2.51
Step-by-step explanation:
Remove the decimal from 8.25 and 20.75.
20.75 inside the house 8.25 out side
then divide
Answer:
A general line is written as:
y = a*x + b
where:
a is the slope
b is the y-intercept.
a) y-intercept = 2 and slope = 7.
This line is:
y = 7*x + 2
b) y-intercept = -1 and is parallel to y= 5x - 7.
Now, if two linear equations are parallel if they have the same slope and different y-intercept. Then if we want a line parallel to y= 5x - 7, this means that the slope of this line must also be equal to 5.
y = 5*x + (-1)
c) y-intercept 2 and is inclined at 45° to the x- axis.
When we have an inclination of A degrees from the x-axis, the slope of the equation is given by: a = Tan(A)
In this case, we have A = 45°
Then the slope is a = Tan(45°) = 1
Then the equation of this line is:
y = 1*x + 2
I can't exactly see if the 10 at the end is negative, but I'm going to assume that it is.
10x - 6y = 8
5x - 10y = -10
= (2, 2)
