Answer: y= -3x + 5
Step-by-step explanation:
y2-y1 divide by x2-x1 = m
therefore you would do 8 - -4= 12 divide by -1 - 3= -4 which gives you 12 divided by -4
m= 12/-4 aka m = -3
and to find the y intercept you should use one of the point coordination to plug it into the formula y=mx+ b
use (-1,8)
8= -3(-1) + b
8= 3+b
subtract 3 from both sides
b= 5
then plug the m and the b into y=mx + b
and you get y= -3 + 5
Answer:
(1/4 x 1 ) = 0.25
or (1/4) x 1 = 0.25
Step-by-step explanation:
We are doing the opposite to finding 25%
Which is 1/4 of 100%
We do this an opposite (not as inverse)
To find percentage increase as you can compare below.
or as percentage increase
230 x 0.25 (x 100) = 287.50
Even though we are not finding increase for 1/4 by changing it to decimal form, this practice does use the (x1) element in brackets and does identify the distribution.
Answer:
the answer to this would be $5.20
Step-by-step explanation:
0.40 times 13 = 5.20
Answer:
x = 18
Step-by-step explanation:
We need to find the value of x.
We know that the sum of angles of a triangle is equal to 180°. So, using this property,
2x+1+3x-1+90 = 180
2x+3x = 180-90
5x = 90
x = 18
So, the value of x is equal to 18.
Actual cost = bill + VAT*bill
= bill*(1 +VAT)
= £463.20*(1 +0.20)
actual cost = £555.84
