1. x-5\ \textgreater \ 2

add 5 to both sides

x\ \textgreater \ 3

2. x+2\ \textless \ -5

subtract 2 from both sides

x\ \textless \ -7

3. x-2\ \textless \ 2

add 2 to both sides

x\ \textless \ 4 and it's the 4th graph option

4. x+5 \geq 10

subtract 5 from both sides

x \geq 5 and it's the 2nd graph option

5. x-5\ \textgreater \ -10

add 5 to both sides

x\ \textgreater \ -5

Answers:

1. 3rd option

2. 1st option

3. 4th option

4. 2nd option

5. 2nd option

Hope this helps!

A child's sandbox is 5 feet wide, 4 feet long, and 3 feet deep. Grace fills the sandbox so that the sand is 2 ½ feet deep. What
8_murik_8 [283]

Answer:

the volume of sand is 50 ft^{3}

Step-by-step explanation:

This problem bothers on the mensuration of solid shapes, rectangular prism.

Given data

Length  l= 4 ft Width w= 5ft\\Height h = 3ft

if the sandbox is filled with sand of 2\frac{1}{2 } ft deep the volume of the sand in the box will be calculated based on the the depth of the sand

converting the depth of sand from mixed fraction to proper fraction we have 2\frac{1}{2} = \frac{5}{2}

the expression for the volume of a rectangular prism is

volume of sand = length * width* height

substituting our data into the expression we have

volume of sand= 5*4 * \frac{5}{2} \\volume of sand = \frac{100}{2} \\volume of sand = 50 ft^{3}

A line includes the points (10, -10) and (1,8). What is its equation in slope-intercept form?
Anettt [7]

Answer:

y=-2x+10

Step-by-step explanation:

m=(y2-y1)/(x2-x1)

m=(8-(-10))/(1-10)

m=(8+10)/-9

m=18/-9

m=-2

------------------

y-y1=m(x-x1)

y-(-10)=-2(x-10)

y+10=-2x+20

y=-2x+20-10

y=-2x+10
