What value of x makes this equation true? 12x - 15 = 6 - 3x

Answers

Answer 1

Answer:

12x - 15 = 6 -3x (add 3x to both sides)

15x - 15 =6 (add 15 to both sides)

15x= 21 (divide both sides by 15 to get x alone)

x= 1.4  (the answer)

Which graph represents the inequality?

Answers

Answer:

A

Step-by-step explanation:

Given the inequality, y > -½, the graph that represents this would have a directed line starting from -½ and pointing to your right. It would also have an unshaded circle, or empty circle, signifying that -½ is not included among the set of possible values of y.

Thus, the right graph would be graph A.

Georgia needs to buy flea treatment for her dog. Pet Store 1 is offering the flea treatment for 40 percent off plus an additional 25 percent off their regular price of $33. Pet Store 2 is offering the same flea treatment for 55 percent off plus an additional 5 percent off their regular price of $34. Which location is offering the better price and how much cheaper is it? The flea treatment is $0.31 cheaper at Pet Store 2. The flea treatment is $1.05 cheaper at Pet Store 2. The flea treatment is $2.05 cheaper at Pet Store 1. The flea treatment is $2.36 cheaper at Pet Store 1.

Answers

Answer:

The flea treatment is $2.05 cheaper at Pet Store 1.

Step-by-step explanation:

Pet store 1

Regular price = $33

40% off the regular price

= 40% of $33

= 0.4 × 33

= $13.2

25% off the regular price

= 25% of $33

= 0.25 × 33

= $8.25

Total paid = $33 - $13.2 - $8.25

= $11.55

Pet store 2

Regular price = $34

55% off of the regular price

= 55% of $34

= 0.55 × 34

= $18.7

5% off of the regular price

= 5% of $34

= 0.05 × 34

= $1.7

Total paid = $34 - $18.7 - $1.7

= $13.6

Difference in price = $13.6 - $11.55

= $2.05

The flea treatment is $2.05 cheaper at Pet Store 1.

Pennies made after 1984 weigh 2.5 grams. How much would 10 pennies weigh?

Answers

Answer:

25 grams

Step-by-step explanation:

Pennies made after 1984 weigh 2.5 grams. How much would 10 pennies weigh?

From the above question:

1 penny = 2.5 grams

10 pennies = x grams

Cross Multiply

1 × x grams = 10 pennies × 2.5 grams

x grams = 25 grams.

Hence, the weight of 10 pennies is 25 grams

Answers

Answer:

( 9, -35 )

Step-by-step explanation:

We can figure out how far the midpoint is from point A and just add the same values to the midpoint's coordinates to get the location of point B.

From A to Midpoint in the X direction:

+ 6

From A to Midpoint in the Y direction:

-15

The coordinate of the midpoint is:

( 3, -20)

3 + 6 = 9

-15 + (-20) = -35

The coordinates of B are:

Enter the difference between the rates of change for these two functions.

Answers

Answer:   2

========================================

Explanation:

Let's find the slope of the graphed line

Use the slope formula on two points from the diagonal line. I'll pick the two points (-1,-2) and (0,2) to get

m = (y2-y1)/(x2-x1)

m = (2-(-2))/(0-(-1))

m = (2+2)/(0+1)

m = 4/1

m = 4

The slope of the graph is 4. This is the same as the rate of change for this graph.

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

Repeat those steps for the data table

I'll pick the first two rows (0,-6) and (2,-2)

m = (y2-y1)/(x2-x1)

m = (-2-(-6))/(2-0)

m = (-2+6)/(2-0)

m = 4/2

m = 2

The slope, or rate of change, here is 2

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

Now subtract the two slopes: 4-2 = 2

The answer is 2.

The difference between the rates of change for these two functions

is 2.

What is slope?

The slope is the rate of change of the y-axis with respect to the x-axis.

The equation of a line in slope-intercept form is y = mx + b, where

slope = m and y-intercept = b.

We know the greater the absolute value of a slope is the more steeper is its graph or the rate of change is large.

We know the slope(m) between the two points (x₁, y₁) and (x₂, y₂) is given by, m = (y₂ - y₁)/(x₂ - x₁).

The two coordinate points of the graph of the line are (0, 2) and (- 1, - 2).

slope(m₁) = (- 2 - 2)/(- 1 - 0).

slope(m₁) = 4.

Slope(m₂) = (- 2 + 6)/(2 - 0).

slope(m₂) = 2.

Therefore, The difference between the rate of change of the two functions is, m₁ - m₂ = 4 - 2 = 2.

What’s the answer ?? The triangle says 84 degrees

Answers

Answer:

x = 48°

Step-by-step explanation:

x + x + 84° = 180°

2x = 180° - 84°

2x = 96°

x = 96°/2

x = 48°

Answer:

84+2a=180

2a=180-84

= 96

2a=96/2

=48

So, each angles are 48 degrees.
