Simplif 1/2t to t/2

t/2 + 8 = 5/2t - 10

Simplify 5/2t to 5t/2

t/2 + 8 = 5t/2 - 10

Multiply both sides by 2

t + 16 = 5t - 20

Subtract t from both sides

16 = 5t - 20 - t

Simplify 5t - 20 - t to 4t - 20

16 = 4t - 20

Add 20 to both sides

16 + 20 = 4t

Simplify 16 + 20 to 36

36 = 4t

Divide both sides by 4

36/4 = t

Simplify 36/4 to 9

9 = t

Switch sides

<u>t = 9</u>

Answer:

t = 9.

Step-by-step explanation:

1/2 t + 8 = 5/2 t - 10

         - 8      -5/2 t

1/2 t - 5/2 t   =   -10 - 8

-2t = -18

t = 9.

Write the expression in exponential form
Elina [12.6K]

Answer:

The basic formula is y=bx y = b x . This can be where 25 is equal to 5 times 5, or 1000 is equal to ten times ten times ten, and can then be written as 52 5 2 or 103 10 3 . The number that is repeated is called the base, and the number of times it repeats is called the exponent, power, or degree.

Select the descriptions that are true of the equation y - 6= - 3(x+2). Select all that apply.
Lapatulllka [165]

The point-slope form:

y-y_1=m(x-x_1)

We have

y-6=-3(x+2)\to y-6=-3(x-(-2))

Therefore

<h3>slope = -3 and the point (-2, 6)</h3>

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

<h3>y + 2 = 2(x - 1)</h3>

2x - y = 4    <em>it's standard form Ax + By = C</em>

y = 2x - 4     <em>it's slope-intercept form y = mx + b</em>

y - x = 4 →<em> </em>x - y = -4  <em>t's standard form Ax + By = C</em>
