Answer:
y=1/2x +2
Step-by-step explanation:
1/2 is the slope, 2 is the y intercept.
Answer:
Step-by-step explanation:
Angles on a straight line add up to 180 so:
180-110 = 70
As this is an isosceles triangle,
y must be 70.
We know y is 70 and there are 2y and one x. A triangle also adds up to 180.
This means:
2y+x = 180
2(70)+x = 180
140+x = 180
x = 40
x = 40 y = 70
Answer:
5:17
Step-by-step explanation:
there are 17 total marbles and 5 that are green. The part is 5 and the whole is 17.
Answer:
n^2+8n+16
Step-by-step explanation:
(n+4)^2
=(n+4) (n+4)
= n^2+4n+4n+16
=n^2+8n+16
Answer:
y=-1
Step-by-step explanation:
it is a straight line graph with no gradient therefore no X value. It crosses the y axis at -1
