7. 2b and b are like terms, $b^{6}$ and 3 $b^{6}$ are like terms

8. 6 and 7 are like terms, 2n and $\frac{n}{4}$ are like terms

9. m and 2m are like terms, 3³ and 2 are like terms

10. 6³ and 6² are like terms, y³ and 5y³ are like terms

Step-by-step explanation:

The like terms are the terms that have the same variable with the same powerAll numerical rational terms are like termsThe numerical terms with the same radical are like terms

Let us solve from No. 7 to No. 10

∵ The terms are 2b, $b^{6}$ , b, $x^{4}$ , 3 $b^{6}$ , 2x²

∵ 2b and b have the same variable and the same power

∴ 2b and b are like terms

∵ $b^{6}$ and 3 $b^{6}$ have same variable b and same power 6

∴ $b^{6}$ and 3 $b^{6}$ are like terms

∵ The terms are 6, 2n, 3n², 6m², $\frac{n}{4}$ , 7

∵ 6 and 7 are numerical rational terms

∴ 6 and 7 are like terms

∵ 2n and $\frac{n}{4}$ have the same variable and the same power

∴ 2n and $\frac{n}{4}$ are like terms

∵ The terms are 10k², m, 3³, $\frac{p}{6}$ , 2m, 2

∵ m and 3m have the same variable and the same power

∴ m and 2m are like terms

∵ 3³ and 2 are numerical rational terms

∴ 3³ and 2 are like terms

#10

∵ The terms are 6³, y³, 3y², 6², y, 5y³

∵ 6³ and 6² are numerical rational terms

∴ 6³ and 6² are like terms

∵ y³ and 5y³ have the same variable and the same power

∴ y³ and 5y³ are like terms

Answer from: Quest

the system of inequity is

$y\leq -x+4$

$3y> x$

step-by-step explanation:

from the given graph it is noticed that we have two related lines. one is solid and another is dashed.

if a line passing through two points, then the equation of line is

$y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)$

the solid line passing through the points (0,4) and (4,0).

$y-4=\frac{0-4}{4-0}(x-0)$

$y=-x+4$

the related equation of solid line is $y=-x+4$ .

similarly, find the related equation of dashed line. the dashed liune passing through the points (0,0) and (3,1).

$y-0=\frac{0-1}{3-0}(x-0)$

$3y=x$

the related equation of dashed line is $3y=x$

from the given graph it is noticed that the point (0,1) lies on the shaded region, therefore the point (0,1) must be satisfied by the related equations.

check the related equations by the point (0,1).

$1=-0+4$

$1=4$

this statement is true if the sign of inequality is < instead of equality. since it is an solid line therefore the sign of inequality will be $\leq$ . the required inequality is

$y\leq -x+4$

similarly, check the second related equation.

$3(1)=0$

it is a dashed line, so this statement is true if the sign of inequality is > . the required inequality is

$3y> x$

15 points write a system of inequalities to represent the shaded portion of the graph
