In these questions, they're asking you to express x in terms of the other algebra.
So we can simply solve this by imaging them as real numerical values.
rx - sx + y = b
First shift +y to the other side, change it to negative.
rx - sx =b - y
Factories rx - sx by picking out the common factor x.
x ( r - s) = b - y
Shift (r-s) to the other side, and we're done.
x = b - y / r - s
Therefore, the final answer is
Now,
G - Ginny's age.
P=G+8, Percy's age.
In 10 years,
G + 10 - Ginny's age in 10 years.
P+10 - Percy's age in 10 years.
<span> In ten years time Percy (P+10) will be three times Ginnys present age (3G).
P+10=3G
Now we have 2 equations, and we can write a system of equations.
</span>(1) P=G+8
(2) P+10=3G -------> G=(P+10)/3, we need to substitute it into equation 1.
( P=(P+10)/3+8) /*3
3P=P +10+24
2P = 34
P = 17
Percy is 17 years old now.
Check,
P=17, G=17-8=9
P+10=3G , 17+10=3*9, 27 = 27 True
Answer:
D. 10 miles
Step-by-step explanation:
As you know 2 inches=5miles so if you add 2 more inches that is equal to 5 miles you will have to add 5 and 5 which equal 10 miles.
Answer:
1
Step-by-step explanation:
go to -4 on the x axis. it corresponds with 1 on the y axis.
<u>Answer:
</u>
The point-slope form of the line that passes through (6,1) and is parallel to a line with a slope of -3 is 3x + y – 19 = 0
<u>Solution:
</u>
The point slope form of the line that passes through the points 
and parallel to the line with slope “m” is given as
--- eqn 1
Where “m” is the slope of the line. 
are the points that passes through the line.
From question, given that slope “m” = -3
Given that the line passes through the points (6,1).Hence we get 
By substituting the values in eqn 1, we get the point slope form of the line which is parallel to the line having slope -3 can be found out.
y – 1 = -3(x – 6)
y – 1 = -3x +18
On rearranging the terms, we get
3x + y -1 – 18 = 0
3x + y – 19 = 0
Hence the point slope form of given line is 3x + y – 19 = 0
