Answer:
y= 3x -5
Step-by-step explanation:
The equation of a line is usually written in the form of y=mx+b, where m is the gradient and b is the y-intercept.
Let's rewrite the equation of the given line in the form of y=mx+b, so we can find its gradient.
y +2= 3(x -1)
y +2= 3x -3 <em>(</em><em>expand</em><em>)</em>
y= 3x -3 -2
y= 3x -5
Gradient of given line= 3
Gradient of unknown line= 3,
since parallel lines have the same gradient.
Susbt. m=3 into the equation:
y= 3x +b
Substitute a coordinate to find the value of b.
When x= 1, y= -2,
-2= 3(1) +b
-2= 3 +b
b= -2 -3 <em> </em><em>(</em><em>-3</em><em> </em><em>on</em><em> </em><em>both</em><em> </em><em>sides</em><em>)</em>
b= -5 <em>(</em><em>simplify</em><em>)</em>
Thus the equation of the line is y= 3x -5.
Answer:
pm = 4
M is the mid point of PQ which means that pm = mq
so MQ = 4
PQ = PM + MQ
= 4 + 4
= 8
Answer:
9.
10.
Step-by-step explanation:
9.
Write 5ab as a difference.
Factor out the greatest common factor (GCFs).
10.
Factor out the GCF which would be mn.
Rewrite.
This is how I do it :)
if it helps you any just translate 40% to .4 just do 40/100, there are two zeros in 100 so move the decimal of 40. over two places 40%=40/100=.4
130*.4=52 so therefore 52 is 40% of 130
