y=2/3y-3

1. y = 2/3 (9)-3 multiply 9 and 2 =18/3

y=18/3-3 divide 18 and 3 =6

y=6-3 subt. 3

y=3

2. -11=2/3x - 3

-11+3 = 2/3 x add 3 to both sides to cancel -3

-8=2/3 x

(3/2)-8 = (2/3)3/2 x multiply both sides by reciprical of 2/3

-24/2 = x divide

-12=x

Answer:

$AC=15.1\ ft$

Step-by-step explanation:

we know that

In the right triangle ABC

The function sine of angle 68 degrees is equal to divide the opposite side SB by the hypotenuse AC

$sin(68\°)=\frac{AB}{AC}$

substitute the values and solve for AC

$sin(68\°)=\frac{14}{AC}$

$AC=\frac{14}{sin(68\°)}$

$AC=15.1\ ft$

The slope of a line is -4 and Y negative intercept is -3 what is the equation of the line written in slope intercept form

lord [1]

Answer:

y = mx + c

m = -4

at y intercept x = 0

(x,y) =(0,-3)

-3 = -4(0) + c

c = -3

therefore the answer is y = -4x + c

A flower shop acquired 80 new customers last year. Costs in the marketing and sales areas were the following:

icang [17]

Using proportions, it is found that the Customer Acquisition Cost was of $1,215.

<h3>What is a proportion?</h3>

A proportion is a fraction of a total amount.

In this problem, the customer acquisition cost is the spending in sales divided by the number of customers added.

80 customers were added, considering costs of 1200 + 9000 + 87000 = $97,200, hence:

97200/80 = $1,215.

If x = 2 calculate the value of x squared- x

monitta

Plug the x value which is 2 back to the x and solve.

I gave you two answers because I wasn’t sure if the question was (x^2) - 2 or x^2-2.
Those two functions look similar but is totally different so keep that in mind.

Hope you have a victorious day!
