Answer:
Step-by-step explanation:
y = 2x - 1
y = x - 8 ------ (i)
substitute y = 2x - 1 in equation (i)
2x - 1 = x - 8
2x = x - 8 + 1
2x = x - 7
2x - x = -7
x = -7
Substitute x value in equation (i)
y = -7 - 8
y = -15
Answer:
f(3)= 33
Step-by-step explanation:
hello :
f(x) =8x+9
put x = 3 you have : f(3) =8(3)+9 = 24 + 9 =33
How many times does 18 go into 7? The answer is 2 times since 14/7 = 2 and we'll have 4 left over. We can say that 18/7 = 2 remainder 4. The remainder of 4 is placed over the denominator 7 to indicate we a fractional part.
Therefore, 18/7 = 2 & 4/7
100 acres to 40 acres
This is already in ratio form, but can be written 2 more ways with a total of 3 ways.
a to b
a:b
a/b
100 acres to 40 acres100:40
100/40
Based on the sequence, the answer for question (a) is 3.5 which is the value of the common difference. The recursive rule for the sequence is x = n + 3.5.
2.5 + 3.5 = 6
6 + 3.5 = 9.5
9.5 + 3.5 = 13
13 + 3.5 = 16.5
16.5 + 3.5 = 20
Hope this helps.
