Answer:

C, D

Step-by-step explanation:

We can solve this graphically and analytically.

Graphically, looking at the attached image below, if we graph the two inequalities and plot the points, you can find the points which are solutions by finding the points in the overlapping area.

This obviously excludes A as it only appears in [tex]y \geq x+2[/tex]

C is included as y [tex]\geq x+2[/tex] includes the point on the line.

D is obviously a solution.

B is however not a solution because is lies on the line [tex]y = \frac{-5x}{2} - 3[/tex], which the inequality excludes.

Analytically, if we can find one of the two inequalities where it is not a solution, it is not a solution of the system.

A: (0, 0)

[tex]y \geq x+2\\0 \geq 0 + 2\\0 \geq 2\\false[/tex]

A is not a solution

B: (-2, 2)

[tex]y \geq x+2\\2 \geq -2 + 2\\2\geq 0\\true[/tex]

[tex]y > \frac{-5x}{2} -3\\2 > \frac{-5(-2)}{2} - 3\\2 > 5 - 3\\2 > 2\\false[/tex]

B is not a solution

C: (0, 2)

[tex]y \geq x+2\\2 \geq 0 + 2\\2 \geq 2\\true\\\\y>\frac{-5x}{2}-3\\2 > -3\\true[/tex]

C is a solution

D:

[tex]y \geq x + 2\\6 \geq -1 + 2\\6 \geq 1\\true\\\\y > \frac{-5x}{2} - 3\\6 > \frac{-5(-1)}{2} - 3\\6 > \frac{5}{2} - \frac{6}{2}\\6 > \frac{-1}{2}\\true[/tex]

D is a solution

Answer:

Options (1), (2) and (3)

Step-by-step explanation:

To solve this problem we will use the property,

"A system of equations will have a unique solution if slopes of the linear equations are different"

Slope of a line passing through two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

Slope of a line passing through (-2, 12) and (3, -23) = [tex]\frac{12+23}{-2-3}[/tex] = (-7)

Option (1)

Slope of a line passing through (-4, 17) and (5, -28) = [tex]\frac{17+28}{-4-5}[/tex] = (-5)

Option (2)

Slope of a line passing through (-2, 16) and (2, -20) = [tex]\frac{16+20}{-2-2}[/tex] = (-9)

Option (3)

Slope of a line passing through (-6, 14) and (4, -16) = [tex]\frac{14+16}{-6-4}[/tex] = (-3)

Option (4)

Slope of a line passing through (-3, 19) and (6, -44) = [tex]\frac{19+44}{-3-6}[/tex] = (-7)

Option (5)

Slope of a line passing through (-5, 32) and (3, -24) = [tex]\frac{32+24}{-5-3}[/tex] = (-7)

Slopes of options (1), (2) and (3) are different.

Therefore, Options (1), (2) and (3) will be the correct options.

Answer:

2/5

Step-by-step explanation:

You need to divide 1/4 by 5/8

Keep change flip- 1/4*8/5

the answer is 8/20

simplified- 2/5

decimal form- 0.4

[tex]\frac{5}{32}[/tex] [tex]many\ 1/4 \ cups\ servings\ are\ in\ 5/8\ cup.[/tex]

Division can be defined as the splitting of a large group into smaller groups such that every group will have an equal number of items. It is an operation used for equal grouping and equal sharing in math.

According to the question

Number of 1/4 cups servings are in 5/8 cup:

Based on the given conditions:

= [tex]\frac{5}{8} \div\frac{1}{4}[/tex]

= [tex]\frac{\frac{5}{8} }{\frac{1}{4} }[/tex]

= [tex]\frac{5}{8\times4}[/tex]

= [tex]\frac{5}{32}[/tex]

[tex]\frac{5}{32}[/tex] [tex]many\ 1/4 \ cups\ servings\ are\ in\ 5/8\ cup.[/tex]

Answer:

1,200

Step-by-step explanation:

Answer: Z= -9.5

Step-by-step explanation:

write the division as a fraction

-4.75=1/2Z

Multiply both sides of the equation by 2

-9.5=Z

then swap the sides of the equation

Z= -9.5

And if they are asking for fraction form then its either

Z= - 19/2, or Z= -9 1/2
