Answer:
Step-by-step explanation:
All the terms in this polynomial are divisible by 3. Factor 3 out of this polynomial:
Now, factor inside the parentheses by grouping:
We knew to split the +2x up into -1x and 3x because -1 and 3 multiply to get -3, which is the last value in the polynomial.
Therefore, the final factored polynomial is .
Answer:
Line y = –x + 4 intersects the line y = 3x + 3
Step-by-step explanation:
The solution is described as the point of intersection of the two lines. The description above is the only one that says anything about that.

<em>Comments on other answer choices</em>
Any line with finite non-zero slope intersects both the x- and y-axes. That fact does not describe the solution to a system of equations.
Any linear equation with an added (non-zero) constant will not intersect the origin. These two equations have +4 and +3 added, so neither line intersects the origin.
Answer:
3.4 tonnes
Step-by-step explanation:
Kg --> tonnes = / 1000
50 x 40 / 1000 = 2. 2 + 1.4 = 3.4.
Answer:
7 1/7
Step-by-step explanation:
For the problem:
5
/7
× 10 = ?
Convert any mixed numbers to fractions:
10 = 10
Multiply all of the numerators by each other. Do the same with the denominators and form a new fraction with these values:
5 × 10
7 × 1
=
50
/7
50 ÷ 7 = 7R1, therefore:
50
/7
= 7 1/7
The result is:
5
7
× 10 = 7 1/7
