Answer:
y=5x
Step-by-step explanation:
Because it has the same slope, both equations must have 5x as their slope. The 2 equations are not going to have the same y intercept, so the +3 can be ignored and replaced with b. You want to plug in (1,5) into you new equation of y=5x+b, to get 5=5(1)+b. Multiply 5 by 1 to get 5, and then subtract 5 from both sides, which gives you 0=b. This means that the y intercept is the origin, so your new equation is y=5x
Note: The expression is missing. Consider the expression is 
.
Given:
The expression is
To find:
Factor form of the given expression by using GCF.
Solution:
We have,
Factors of each term:
The common factors are 2, 2 and 2. So,
Taking out the greater common factor (GCF) in the given expression, we get
Therefore, the required expression is 
and the correct option is C.
Answer:
iii) Use algebraic methods
Step-by-step explanation:
There are various method of finding an accurate solution to a system of linear equations.
They are i) graphing method: ii) algebraic method: iii) Matrices method:
iv) determinant method: v) guess method vi) Cramer's rule etc
Guess and check is not reliable because guess is possible only for integers or numbers with 1 or 2 decimals. SOmetimes guess may give unreliable results. And every time after the guess, checking and verifying will be time consuming and laborious
Graphing the lines may be accurate but writing tables for each line, choosing scales and drawing lines to find points of intersection may be time consuming.
Algebraic methods using are easy to understand, reliable, and less time consuming but 100% accuracy. There are a number of ways in algebraic method also such as substitution, elimination or cross multiplication, etc
Thus option iii) is right
Answer and Step-by-step explanation:
The answer is 54.
We see that each time, the number is being multiplied by 1.5.
54 times 1.5 = 81 * 1.5 = 108
54 times 2 = 108
<u>54 is the starting number, because when you multiply 54 by 1, you get 54 for y.</u>
