Can you walk me through the steps: 3t+2+2t-4t=3+5

neonofarm [45]

To find t? yes.

First, you combine like terms so 3t and 2t and 4t. Add 3 and 2 and then subtract the 4. you will end up with 1t (just t) +2. you cannot add the 2 because it does not have the variable t. on the other side, you will also combine like terms. so 3+5=8. now your equation is t+2=8. this is the part where you will try to get t by itself. subtract the 2 from the left side. but in order for the equation to stay equal to itself, you have to subtract 2 from the right side as well. this will leave you with your final answer of t=6.

the turnout for the game is expected to reach 80,000 fans of which 57% expected to drive. An average of three fans come in each

Vera_Pavlovna [14]

Answer:

13,200 vehicles

Step-by-step explanation:

57% of 80,000 is 45,600

3 people per car for 2000 vehicles is 6,000

45,600-6,000=39,600

lastly 39,600/3=13,200

Write an equation in standard form for the line, where the points (-2, -1) and (0, 4) are on the line

DedPeter [7]

Answer:

An equation in standard form for the line is:

$\frac{5}{2}x-y=-4$

Step-by-step explanation:

Given the points

(-2, -1) and (0, 4)

The slope between two points

$\mathrm{Slope\:between\:two\:points}:\quad \mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}$

$\left(x_1,\:y_1\right)=\left(-2,\:-1\right),\:\left(x_2,\:y_2\right)=\left(0,\:4\right)$

$m=\frac{4-\left(-1\right)}{0-\left(-2\right)}$

$m=\frac{5}{2}$

Writing the equation in point-slope form

As the point-slope form of the line equation is defined by

$y-y_1=m\left(x-x_1\right)$

Putting the point (-2, -1) and the slope m=1 in the line equation

$y-\left(-1\right)=\frac{5}{2}\left(x-\left(-2\right)\right)$

$y+1=\frac{5}{2}\left(x+2\right)$

$y=\frac{5}{2}x+4$

Writing the equation in the standard form form

As we know that the equation in the standard form is

$Ax+By=C$

where x and y are variables and A, B and C are constants

$y=\frac{5}{2}x+4$

$\frac{5}{2}x-y=-4$

Therefore, an equation in standard form for the line is:

$\frac{5}{2}x-y=-4$

A fly is standing on a boulder, which is rolling down a hill. The forward torque the fly exerts on the boulder when it has rolle

bulgar [2K]

Question:

A fly is standing on a boulder which is rolling down a hill. The forward torque the fly exerts on the boulder when it has rolled 'x' meters, in Newton meters is given by

$\tau(x) = \dfrac{2}{1,000} \cdot sin \left(\dfrac{2 \cdot \pi \cdot (x + 0.2)}{4} \right )$

Answer:

y = 0

Step-by-step explanation:

The general form of the sine function is presented as follows;

y = A·sin[B·(x - C)] + D

Where;

A = The amplitude

C = The horizontal shift

D = The vertical shift above the generic midline of y = 0 = Constant

By comparison with the general equation for torque, we have that the constant D = 0, therefore, the vertical shift = 0, and the midline of the the given function = The midline of the generic sine function which is y = 0.
