Answer:
8.5
Step-by-step explanation:
58.65/6.9= 8.5
Answer= 3
trust me it is 3
let me explain
y=mx +b
=(-1)x + (3)
= -1x + 3
y= -x+3
therefore the answer is = 3

answer is b!!
Step-by-step explanation:
Answer:
x = 7; y = 4 1/3
Step-by-step explanation:
The solution is the point of intersection of the lines.
Read the point of intersection.
You can also solve the system using algebra.
y = 1/3 x + 2
y = 4/3 x - 5
1/3 x + 2 = 4/3 x - 5
x + 6 = 4x - 15
-3x = -21
x = 7
y = 1/3 x + 2
y = 1/3 × 7 + 2
y = 2 1/3 + 2
y = 4 1/3
Answer: x = 7; y = 4 1/3
Answer:
y = 3/7x + 51
Step-by-step explanation:
y = 3/7x + 11 is parallel to the line so it means that both of their gradient are same so:
y = mx + c
m= gradient point = (-21 , 42)
= 3/7
now we sub the m and the point into the formula which is y= mx+c because we should find the c first then we can find the equation of the line:
42 = 3/7 (-21) + c
42 = -9 + c
42 + 9 = c
51 = c
c = 51
now you hv to rewrite again the equation become y= 3/7x + 51
So now your final answer is : y = 3/7x +51
