Answer:

y = 3x +1

Step-by-step explanation:

The line intersects the y-axis at y=1, so the y-intercept is ...

b = 1

The line rises 3 grid squares for each 1 grid square to the right, so the slope is ...

m = rise/run = 3/1 = 3

Then the slope-intercept equation of the line is ...

y = mx +b

y = 3x +1

Challenge A gold mine has two elevators, one for equipment and another for the miners. The

OLEGan [10]

Step-by-step explanation:

The equipment elevator is at a depth of 176 feet (-176 feet), while the miners elevator is at a depth of 210 feet (-210 feet) below the surface

ii. The miners elevator is deeper than that of the equipment.

The speed of an object is the rate at which the object moves.

i.e speed = \frac{distance}{time}

time

distance

Thus,

Speed of the equipment elevator = 4 feet per second

Speed of the miners elevator = 15 feet per second.

Time of descent of the equipment elevator = 30 + 14

= 44 seconds

So that, the distance of the elevator at this time is;

speed = \frac{distance}{time}

time

distance

⇒ distance = speed x time

= 4 x 44

= 176

distance = - 176 feet

The distance of the miners elevator after 14 seconds is:

speed = \frac{distance}{time}

time

distance

⇒ distance = speed x time

= 15 x 14

= 210

distance = - 210 feet

Thus after another 14 seconds, the equipment elevator is at a depth of 176 feet (-176 feet), while the miners elevator is at a depth of 210 feet (-210 feet) below the surface.

Therefore, the miners elevator is deeper than that of the equipment.

Select all of the values of x that make the inequality -x+6= or grater than 10 true.

Answer:

2/5

3/2

Step-by-step explanation:

Note that:

> = Greater than

< = Less than

≤ = Less than or equal to

≥ = Greater than or equal to

Solution:

Since it given that 27/7n > 4/3

It means that

27/7n is greater than 4/3.

Now going through all answer choices:

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

27/7(2/5) = 1 19/35

1 19/35 is greater than 4/3

Thus, 2/5 is true.

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

27/7(1/3) = 1 2/7

1 2/7 isn't greater than 4/3

Thus, 1/3 is false.

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

27/7(1) = 3 6/7

3 6/7 is greater than 4/3

Thus, 1 is true.

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

27/7(2/9) = 6/7

6/7 isn't greater than 4/3

Thus, 2/9 is false.

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

27/7(3/2)=5 11/14

5 11/14 is greater than 4/3

Thus, 3/2 is true.

Question 1 (1 point)

Natalija [7]

Answer: OPTION B.

Step-by-step explanation:

Given the equation $48=-8(\frac{3b}{4}+2)$ you can find an equivalent equation by simplifying it.

You need to remember the multiplication of signs:

$(-)(-)=+\\(+)(+)=+\\(+)(-)=-$

Now you can apply the Distributive property:

$48=\frac{(-8)(3b)}{4}+(-8)(2)\\\\48=\frac{-24b}{4}-16$

Simplifying the equation, you get:

$48=-6b-16$

You can observe that this equivalent equation matches with the equation provided in option B.
