Answer:
And the results would apply to every fonction.
Y= mx+c
So m= the gradient (slope)
And c=the y intercept (x,y= -3,4)
So it should be
Y=1/3x+4
Answer:
0.330
Step-by-step explanation:
Divide the number of hits (189) by the number of bats (572)
189/572=0.330
Answer:
81
Step-by-step explanation:
Given the expression: 
To make it a perfect square, we follow the following steps.
Divide the coefficient of x by 2
- Coefficient of x=18, 18/2=9
Square It
Add it to the expression
This is written as a perfect square as: 
The constant term required therefore is 81.
Let
x-------> the amount of
solution
y--------> the amount of
solution
we know that
so

-------> equation A
-------> equation B
substitute equation A in equation B




find the value of y


therefore
The student need
of
solution and
of
solution
<u>the answer is</u>
A) The percent values were written incorrectly in the equation
B) The amount of 7% solution should be written as 1 – x, not x – 1.
