-2.8=x+1.3
just find the answer :))

Answers

Answer 1

Answer: x=-4.1

Step-by-step explanation:

Let's take our equation

-2.8=x+1.3

-1.3     -1.3

-4.1=x

x=-4.1

Answer 2

Answer: - 4. 1

Step-by-step explanation:

Step 1:

Flip the equation.

x + 1.3 = − 2.8

Step 2: Subtract 1.3 from both sides.

x + 1.3 − 1.3 = −2.8 − 1.3

x = − 4.1

(x - 2) => x = 2

f(x) = f(2)

___________

= 2x³ - 5x² + 3x + 7

= 2(2)³ - 5(2)² + 3(2) + 7

A decorator uses the expression 6s2 to model the minimum amount of fabric needed to cover an ottoman in the shape of a cube. If s=2 and the fabric is measured in square feet, what is the value of the expression?

square feet

Answers

Answer:

Divide the measurement by 36 to determine the number of yards needed. For example, if the pattern pieces cover an area of floor equal to 72 inches in length, then divide 72 by 36 to get 2, the number of yards of 54-inch wide fabric needed for the ottoman.

A candy bar manufacturer is interested in trying to estimate how sales are influenced by the price of their product. To do this, the company randomly chooses 6 small cities and offers the candy bar at different prices. Using candy bar sales as the dependent variable, the company will conduct a simple linear regression on the data below: What is the estimated average change in the sales of the candy bar if price goes up by $1.00?

Answers

Answer:

-48.19

Step-by-step explanation:

Given the data:

City Price ($) Sales

River Falls 1.30 100

Hudson 1.60 90

Ellsworth 1.80 90

Prescott 2.00 40

Rock Elm 2.40 38

Stillwater 2.90 32

We could obtain a simple regression model of the data above using a linear regression calculator :

The regression model obtained is :

ŷ = -48.19277X + 161.38554

The change in sales per unit change in price is the value of the slope or gradient :

From the general linear regression equation :

y = mx + c

m = slope ;

Slope = - 48.19 ; hence, there is a drop in sales by about 48 units as the change in sales as the price of candy bar goes up by about $1.00

WILL GIVE BRAINLY PLZ HELP!!

Answers

Answer:

(5,0) and (0,6)

Step-by-step explanation:

1. Rearrange y as LHS

12x+10y=60

10y=60-12x

y=60/10-12/10x

y=-6/5x+6

2. Find intercepts

x = 0 is y intercept

y = 6

y = 0 is x intercept

-6=-6/5x

6=6/5x

30/6=x

x = 5

3. X-int (5,0) Y-int (0,6)

In a certain year, the average e-mail user sent or received 138 e-mails each day. The number of e-mails received was 2 more than thrice the number sent. How many were sent and how many were received each day?

Answers

Answer:

the 34 would be sent and 104 would be received

Step-by-step explanation:

The computation of the number of sent and number of received each day is shown below:

Let the number sent be x

And, the number received be y = 3x + 2

Now according to the question

x + 3x + 2 = 138

4x = 136

x = 34

So, the y = 34(3) +  2

= 104

hence, the 34 would be sent and 104 would be received
