The linear equations graphed in the coordinate plane below intersect.

Which coordinate point is the solution

Answer:

(-1, -3.5)

Step-by-step explanation:

The coordinates of the midpoint of segment AB can be obtained via the midpoint formula:

Xmp = (Xa + Xb)/2

which in our case is:  (-7 + 5)/2 = -2/2 = -1

Ymp = (Ya + Yb) / 2

in our case: (2 - 9) / 2 = -7/ 2= -3.5

Therefore select the point: (-1, -3.5) from your given list of options.

Answer:

1/7

Step-by-step explanation:

-(x + 3) = 8x - 4 - 2x

-x - 3 = 8x - 4 - 2x

combine like terms

-x - 3 = 6x - 4

add

-x = 6x -1

subtract

-7x = -1

divide

x = 1/7

Answer:

x = 1/7

Step-by-step explanation:

-(x + 3) = 8x - 4 - 2x

-x - 3 = 8x - 4 - 2x

-x - 3 = 6x - 4

-x = 6x -1

-7x = -1

x = 1/7

Answer:

  r ≈ 19.0

  s ≈ 17.7

Step-by-step explanation:

The relevant trig relations are ...

  Sin = Opposite/Hypotenuse

  Cos = Adjacent/Hypotenuse

So, you have ...

  cos(43°) = r/26

  r = 26·cos(43°) ≈ 19.0

__

  sin(43°) = s/26

  s = 26·sin(43°) ≈ 17.7

Answer:

  14(x +5)

Step-by-step explanation:

The denominator of the first expression is ...

  2x+10 = 2(x +5)

The denominator of the second expression is ...

  7x +35 = 7(x +5)

The least common denominator (LCD) is the product of the unique factors in these denominators:

  2×7×(x +5)

  = 14(x +5) . . . . least common denominator

  = 14x +70

To make a histogram, follow these steps:

What does a histogram mean?

Histograms are equivalent to bar charts; they are a means for data counts to be displayed. Real counts against categories are seen in a bar graph; the bar height represents the number of objects in that category. In "bins", a histogram reveals the same categorical variables.

Create a Histogram: Stages for Steps

Sample question: With the following test scores, construct a histogram: 99, 97, 94, 88, 84, 81, 80, 77, 71, 25.

Phase 1: Diagram the x and y axes and label them. The x-axis would be labelled "score" for this case, and the y-axis would be labelled "relative percentage of frequency ."

Phase 2: Pick the number of bins (in statistics, how to choose bin sizes) and mark your graph. Query, Grou, Grou, for this sample,It's a smart option for groups of 10 (the x-axis values are the bins) (it looks like you'll have 5 bars of one or two objects in the group).

Step 3: To get an indication of where to put the frequency "ticks," divide 100 by the number of data points. In our data collection, we have 10 objects, so it makes sense to count 100/10 = 10 percent (one item would equal 10 percent of the total).

Build a histogram

Step 4: Count how many objects are in each bin and then outline a rectangle corresponding to the percentage of the total filled by the bin on the graph. The first bin (20-30) has 1 object in this sample data package, with 70-80 getting two items. When an object lands on a bin boundary (i.e. 80), bring it up in the next bin (80 will go to 80-90)

This question is incomplete, the complete question is;

The owners of Spiffy Lube want to offer their customers a 10-minute guarantee on their standard oil change service. If the oil change takes longer than 10 minutes to complete, the customers is given a coupon for a free oil change at the next visit. Based on past history, the owners believe that the timer required to complete an oil change has a normal distribution with a mean of 8.6 minutes and a standard deviation of 1.2 minutes.

Suppose management could improve the process by reducing the mean time required for an oil change (but keeping the standard deviation the same). How much change in the mean service time would be required to allow for a 10-minute guarantee that gives a coupon to no more than 1 out of every 25 customers on average

Answer:

Required change in the mean service time is 7.8988

Step-by-step explanation:

Given the data in the question;

How much change in the mean service time would be required to allow for a 10-minute guarantee that gives a coupon to no more than 1 out of every 25 customers on average

let mean = μ

p( x > 10 ) ≤ (1/25)

p( x > 10 ) ≤ 0.4

p( x-μ / 1.2  > 10-μ / 1.2 ) ≤ 0.4

(10-μ / 1.2 ) ≤ 0.4

(10-μ / 1.2 ) ≥ [tex]q_{norm}[/tex] ( 0.96 )

(10-μ / 1.2 ≥ 1.751

10-μ  = ≥ 1.751 × 1.2

10-μ  ≤ 2.1012

μ ≤ 10 - 2.1012

μ ≤ 7.8988

Therefore, required change in the mean service time is 7.8988

The area of the triangle given in the figure is 6 square units.

A triangle is a three-sided polygon that consists of three edges and three vertices.

We need to find the area of triangle.

Area of triangle is 1/2 × Base × Height

The length of base is 6 units.

The length of height is 2 units.

Now let us plug in the value of base and height into the given formula of triangle.

Area of triangle =1/2×2×6

=6 square units

Hence, the area of the triangle given in the figure is 6 square units.

Answer: 9x^2-2x+8/2x(x-2)

Step-by-step explanation:

Answer: C

Step-by-step explanation:

Answer:

x=7

Step-by-step explanation:

Simplifying

3x + 2(4 + 6x) = 113

3x + (4 * 2 + 6x * 2) = 113

3x + (8 + 12x) = 113

Reorder the terms:

8 + 3x + 12x = 113

Combine like terms: 3x + 12x = 15x

8 + 15x = 113

Solving

8 + 15x = 113

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-8' to each side of the equation.

8 + -8 + 15x = 113 + -8

Combine like terms: 8 + -8 = 0

0 + 15x = 113 + -8

15x = 113 + -8

Combine like terms: 113 + -8 = 105

15x = 105

Divide each side by '15'.

x = 7

Simplifying

x = 7

Answer:

x=7

Step-by-step explanation:

3X+2(4+6X)=113

=> 3X +2x4+2x6X=113

=> 3X+8+12X=113

=> 3X+12X=113-8

=>15X=105

=>X=7
