in order for an object to begin to move. stop moving, or change direction, which of the following must be present?​

Answer:

x=142, y=-360. (142, -360).

Step-by-step explanation:

5x+2y=-10

3x+y=66

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

5x+2y=-10

-2(3x+y)=-2*66

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

5x+2y=-10

-6x-2y=-132

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

-x=-142

x=142

3(142)+y=66

426+y=66

y=66-426

y=-360

Answer:

1- 5x+2y+−2y=−10+−2y

5x=−2y−10

[tex]\frac{5}{5}[/tex]= [tex]\frac{-2y-10}{5}[/tex]

x= [tex]\frac{-2}{5}y-2[/tex]

2-  3x+y+−y=66+−y

3x=−y+66

[tex]\frac{3x}{3} = \frac{-y+66}{3}[/tex]

[tex]x=\frac{-1}{3}y+22[/tex]

The spider would reach the height of 74 cm on 24th February by the end of the day.

An expression in mathematics is a combination of terms both constants and variables.

Given is that a spider is climbing up a wall. During the daytime it climbs 5 cm, but then slips back 2 cm during the night.

The net distance covered by the spider in one day -

D{n} = 5 cm - 2 cm = 3cm

The spider would reach 74 cm up in -

{x} = 74/3

{x} = 24.7

This means that the spider would reach the height of 74 cm on 24th February by the end of the day.

Therefore, the spider would reach the height of 74 cm on 24th February by the end of the day.

the Volume of the Pyramid = Volume of Prism / 3

198cm^3 / 3  = 66cm^3

Answer:

B

Step-by-step explanation:

Reflect x-axis means (x,y) becomes (x, -y)

Shrink by 1/3 means f(x) = x becomes f(x) = 1/3x

Up 4 units means f(x) = x becomes f(x)= x + 4

So lets put that together

[tex]f(x) = \sqrt{x}[/tex]

[tex]f(x) = -\sqrt{x}[/tex]

[tex]f(x) = -\frac{1}{3} \sqrt{x}[/tex]

[tex]f(x) = -\frac{1}{3} \sqrt{x} + 4[/tex]

Answer:

161

Step-by-step explanation:

Given the functions

f (x) = 2x^2 – 1

g(x) = 3x

we are to find f(g(3))

First look for the composite function f(g(x))

f(g(x)) = f(3x)

f(3x)  = 2(3x)² - 1

f(3x)  = 2*9x² - 1

f(3x)  = 18x² - 1

f(g(x)) =  18x² - 1

Substitute x  = 3 into the result

f(g(3)) = 18(3)² - 1

f(g(3)) = 18*9- 1

f(g(3)) = 162-1

f(g(3)) = 161

Hence f(g(3)) is 161

Answer:

it would be 457.2 cm or if you want it simplified then it would be 457 cm
