To find the coordinates of a point in a coordinate system, do the inverse. Start at the point and trace a vertical line up or down to the x-axis. There you have your x-coordinate. Then repeat the process, but this time follow a horizontal line to determine the y-coordinate.

A point is identified by its ordered pair of (x, y). The first number represents the x-coordinate, while the second represents the y-coordinate.

To graph a point, you draw a dot at the coordinates of the ordered pair. It's usually a good idea to begin at the beginning.

An ordered pair of integers, such as an x-coordinate, which is a number on the x-axis, and a y-coordinate, which is a number on the y-axis, can be used to identify each point. Parentheses are used to indicate ordered pairings (x-coordinate, y-coordinate). The starting point is at (0,0).

Her painting rate in hours per window frame will be;

⇒ 0.25 hours per window frame

Division method is used to distributing a group of things into equal parts. Division is just opposite of multiplications. For example, dividing 20 by 2 means splitting 20 into 2 equal groups of 10.

Given that;

Joyce painted 8 window frames in 5 hours while earning money for college.

Here, Joyce painted 8 window frames in 5 hours while earning money for college.

Hence, Her painting rate in window frames per hour is,

⇒ 8/5

⇒ 1.6 frames per hour

And, Her painting rate in hours per window frame is,

⇒ 5/8

⇒ 0.25 hours per window frame

Thus, Her painting rate in window frames per hour = 1.6 frames per hour

Her painting rate in hours per window frame = 0.25 hours per window frame

$b+$12 is the equation that will determine the amount of the original bill

percentage, a relative value indicating hundredth parts of any quantity.

Given that The friend told the waiter to remove the $12 dessert from Stan’s bill.

Stan tipped the waiter 20% on the reduced bill, which was a $15 tip

We need to write an equation that will determine the amount of the original bill b.

Let us find what 20% of amount will be 15

20/100×b=15

0.2x=15

b=15/0.2=75

The reduced bill is $75.

As before $12 is removed

$b+$12=$87

$87 is the original bill and 15 is the tip.

Hence, $87 is the original bill.

Answer:

The correct option is A.

Step-by-step explanation:

When we have two congruent figures, the correspondent sides of the figures are related by the same constant C.

In the case of the image.

h is the left side of the smaller triangle.

h + j is the left side of the larger triangle.

Then we have the relation:

(h + j) = C*h

If we isolate C, we get:

C = (h + j)/h

We can also write this for the other side (the bottom one)

k*C = (k + i)

C = (k + i)/k

Then we have:

(h + j)/h = (k + i)/k

We can rewrite this as:

h/h + j/h = k/k + i/k

1 + j/h = 1 + i/k

We can subtract 1 in each side to get:

j/h = i/k

This is almost the same we can see in option A (its inversed)

If we apply the inverse to both sides, we get:

(j/h)^-1 = (i/k)^-1

h/j = k/i

Which is the same equation that we can see in option A.

Then the correct option is A.

How do you find the value of log base 2?

Properties of Log Base 2

Multiply two numbers with base 2, then add the exponents. Divide two numbers with the base 2, subtract the exponents. Power Rule: Raise an exponential expression to power and multiply the exponents.

Use the change-of-base formula:

since we know that natural log and log with base 10 are different

So, if we want to write log3(6) as a logarithm of base 2, in these example a = 3, x = 6, b = 2:

Answer:

x= 35⁰ - obtuse triangle

Step-by-step explanation:

since the sum of angles of the triangle = 180⁰

(3x-5) + (x+10) + (x) =180⁰

5x+5= 180

(subtracting 5 from both sides)

5x=180-5

5x= 175

(dividing by 5)

x= 35⁰

so the angles of the triangle are

(3x-5) = 105-5= 100⁰

(x+10) = 45⁰

(x) = 35⁰

then this triangle is an obtuse triangle

Answer:

1. $145

2. 45+25x=total $

Step-by-step explanation:

45+(25•4)=145

Step-by-step explanation:

Given:

10 GB included with plan

$45 per month

$25 per GB over the amount of 10

Need to find out:

How much would Kadeesha have to pay in a month where she used 4 GB over the limit, how much would it be if it went over xx GB?

Let's solve the first problem:

10 GB included + 4 GB (over) =14 total GB

$45=10GB. $25×4= 4 GB over.

$45+$100=$145

Therefore, Kadeesha would have to pay $145 if she went 4 GB over the 10.

Now, let's solve the next problem:

So, for this problem we are going to find the amount it wil be in other various amounts. To do this we will create a chart /table

$45 ------> 10GB

$70 -----> 11 GB

$95 ----> 12 GB

$120 ---> 13 GB

$145 ---> 14 GB

$170 ---> 15 GB

and so on....

but here we can see any given amount will be her usual Phone bill amount ($45), with the 10 GB and an additional $25 for every added GB.

Answer:

39°

Step-by-step explanation:

At the section the angles are connected, meaning that the angle across from w is the same as w and same applied to x. To find y, you first need to find w, to find the 2nd angle of the triangle of the right.

To do this, you need to add up 42 + 85.

(All triangles angles = 180)

42+85=127

subtract this from 180 to find angle w

180 - 127 = 53

53 = Angle w, which is the same as the angle across from angle w (second angle).

Second, take 53 + 88 = 141

Subtract this from 180

180-141 = 39.

39 is y°

or

y° = 39

10 = 1/2(x)4)

2x = 10

x = 5

Answer:

The value of x (which is also the height of this triangle) is x = 5 units.

Step-by-step explanation:

The formula for the area of a triangle of base b and height h is

A = (1/2)(b)(h).

Here A = 10 units² = (1/2)(4 units)(x).

Multiplying both sides by 2 yields    20 units² = (4units)(x), and thus  20 units²
