Try 3 because 3 times 3 is. 9
There are 16 ounces in one pound. So we do 7 divided by 16 to get our answer.
7 / 16 = 0.4375 ≈ 0.4 lbs
7 oz is approximately 0.4 lbs.
Answer:
(x + + )(x + - )
Step-by-step explanation:
solve the polynomial for x then express in product of factor form
Solve
x² + x - 10 = 0 ( add 10 to both sides )
x² + x = 10
Using the method of completing the square
add ( half the coefficient of the x- term )² to both sides
x² + 2( )x + = 10 +
(x + )² = ( take the square root of both sides )
x + = ± = ± ( subtract from both sides )
x = - ±
Thus corresponding factors are
(x - (- - ) ) and (x - (- + ), that is
(x + + ) and ( x + - )
Thus
x² + x - 10 = ( x + + )(x + - ) ← in factored form
Answer:
1. 3
2. 12
3. 27
Step-by-step explanation:
Both y = x and y = x -3 have a slope of 1
y = x passes through the origin while y = x -3 intersects the y-axis at the point (0, -3)
Both functions represent a straight line of the form y = mx + c
where m is the slope
c is the y-intercept
For the function y = x
The slope = 1
The y-intercept = 0
That is the line y = x passes through the origin
For the function y = x-3
The slope = 1
The y-intercept = -3
The line passes intersects the y-axis at (0, -3)
The graphs of y=x and y = x - 3 are attached below
