Answer:
a =5
Step-by-step explanation:
4a -3 = 2a +7
Subtract 2a from each side
4a-2a -3 = 2a-2a +7
2a-3 =7
Add 3 to each side
2a-3+3 = 7+3
2a=10
Divide each side by 2
2a/2 = 10/2
a =5
Answer:

Step-by-step explanation:
Notice that A, B, and C constitute the vertices of a right angle triangle, with the right angle at the vertex A.
If we count the number of squares separating B and A (one of the legs of the right angle triangle) we find 8 units.
If we count the number of squares separating C from A (the other leg of the right angle triangle), we get: 3 units.
Then, we apply the Pythagorean theorem to find that length of the triangle's hypotenuse which is the segment BC:

Answer:
C.
Step-by-step explanation:
14/3 = 4.7 which seems about right for the Y-intercept & the gradient is - 1/3.
Gradient = rise /run
= 1/3
Hope this helps!
Answer:
Y-3 = 2(x+1)
open the brackets
Y-3 = 2x+2
Y = 2x+5..... this is the answer when solving for Y
if were solving for x:
Y-3 = 2x+5
Y-8 = 2x
