Answer: 1 3/4
Step-by-step explanation: First, convert 4 1/2 and 2 3/4 to have like denominators.
4 1/2 = 4 2/4 because 1 x 2 = 2 and 2 x 2 = 4 = 2/4
2 3/4 stays the same.
Now, subtract 4 2/4 - 2 3/4 (4 x 4 = 16 + 2 = 18) and (2 x 4 = 8 + 3 = 11)
18/4 - 11/4 = 7/4 or 1 3/4
Answer:
C
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
calculate m using the slope formula
m = 
with (x₁, y₁ ) = (0, 6) and (x₂, y₂ ) = (4, 0) ← 2 points on the line
m = 
= 
= - 
, then
y = - x + c
the line crosses the y- axis at (0, 6 ) ⇒ c = 6
y = - x + 6 ← equation in slope- intercept form
multiply through by 2 to clear the fraction
2y = - 3x + 12 ( add 3x to both sides )
3x + 2y = 12 ← equation in standard form
Answer:
Step-by-step explanation:
You must multiply the first two equation which is 5x+1 and x this will give you
5x^2 + x. The bold goes in the first box.
Then do the same thing for 2x+1 and x+1 which will give you 2x^2+2x+x+1 or 2x^2+3x+1. This goes in the second box.
In the last box you will add 5x^2 +x and 2x^2 +3x +1, which gives you 7x^2 +4x +1.
Goes in the last box.
Hope this helps you.
