solve the equation ( exponential equations)

[tex] {3}^{4} = {3}^{2x + 8} [/tex]


​

Answer: x = 30' , y = 45'

hope this helps

Step-by-step explanation:

U is 90' it's a right triangle

well simple VRT you already know 2 angles which is 60' and 90'

R = 60'

V = 90'

T = x

you know that a triangle = 180'

so you do

180 - 60 - 90 = x

30 = x

if you want to do y

then you already know that U is 90' on both sides.

since you also know S,

S = 45'

U = 90'

V = y

180 - 90 - 45 = y

45 = y

Step-by-step explanation:

The required number of coins are would only by quarters so that 12 coins shows the values of $3.

The equation model is defined as the model of the given situation in the form of an equation using variables and constants.

Here,
dime = $0.1
quarter = $0.25

Now,
Let the number of dimes be x and number of quarter be y,
x + y = 12
x = 12 - y - - -- -(1)

According to the question,
0.1x + 0.25y = 3  -- - -(2)
y = 12

Now,
x = 0

Thus, the required number of coins are would only by quarters so that 12 coins shows the values of $3.

Answer:

UZ = 44

Step-by-step explanation:

3x+8 = 6x-28

36 = 3x

Step-by-step explanation:

Since he is charging $12.52 per hour and only working 40 hr per week than multiply the ammount by the number of hrs per week. Therfore the answer will be $12.52*40=$500.8

Answer:

x = 2

Step-by-step explanation:

Given the equation as;

log 3 + log x - log(x + 1) = log 2

collect like terms

log x - log(x + 1) = log 2-1og 3

Re-write the equation by applying laws of logarithms in that when you subtract logs you divide the numbers/terms. This will give

log [ x / x+1 ] = log [2/3]

Cancel log on both sides to remain with;

x/ x+1 = 2/3

Apply cross-product

3{x} = 2{x+1}

3x = 2x + 2

3x-2x = 2

x = 2

Answer:  y = ¹/₂x + 2

Step-by-step explanation: This is slope-intercept form. y = mx + b

m is the slope. Rise/run

The difference in y-values is the rise. The difference in x-values is the run.

Look for places where the graphed line intersects the grid. Count the squares. Here, the graphed line rises 1 square as it runs 2 squares.

b is the y-intercept. Here, that is 2

m>=-5

Step-by-step explanation:

-0.5<=m/10

m>=-0.5(10)

m>=-5

Answer:

We need to calculate the height of the 6mi by 8mi  by 10mi triangle.  In order to do this we first must calculate its area.

To calculate the area we need to use Heron's formula.

We then learn that the area is 24.

Since triangle area = .5 * base * height

then height = 2 * area / base

height = 2 * 24 / 10

height = 4.8

Triang Prism Surface area = 2 * Triangle Area + height * (a + b + c)

Triang Prism Surface area = 2 * 24 + 4.8 * (6 + 8 + 10)

Triang Prism Surface area = 48 + 4.8 * 24

Triang Prism Surface area = 163.2
