y+1>2x-4

minus 1 on both sides

y>2x-5

slope is 2/1

Answer:

Step-by-step explanation:

the given angle measurments are x, (x + 18), and 2(x - 5)

knowing that the angles add up to 180, you can write the equation:

x + (x + 18) + 2(x - 5) = 180

Then you solve the equation

so our equation is:

x + x + 18 + 2(x - 5) = 180

*combine like terms

2x + 18 + 2(x - 5)

*distribute the 2

2x + 18 + 2x - 10

* combine like terms

4x + 8 = 180

* subtract 8 from both sides

4x = 172

* divide both sides by 4

x = 43

so knowing that x is 43, we can plug that in to the original given angle measurements:

the top angle which was x + 18 becomes 43 + 18, or 61

the bottom right angle was 2(x - 5), now it's 2(43 - 5) or 2(38) which is 76

and the other one was x so it's 43 degrees

We can check our work by adding them together.

61 + 76 + 43 = 180

they equal 180 as the angles of a triangle should.

Note: most of these numbers should have degree symbols, but I don't know how to type that.

Answer:

A

Step-by-step explanation:

the angles are adjacent angles on a straight line and sum to 180°, so

5x + 4x = 180

9x = 180 ( divide both sides by 9 )

x = 20

then

∠ MTQ = 5x = 5 × 20 = 100°

∠ GTQ = 4x = 4 × 20 = 80°

[tex]f(x-a) \implies f(x) \: \textsf{translated}\:a\:\textsf{units right}[/tex]

For a =2

Given:

Given that the radius of the circle is 2 inches.

We need to determine the area of the remaining square.

Area of a square:

Given that each circle has a radius of 2 inches.

Then, the diameter of each circle is 4 inches.

Hence, the side length of the square is 2 × 4 = 8 inches.

The area of the square is given by

[tex]A=s^2[/tex]

[tex]A=8^2[/tex]

[tex]A=64[/tex] [tex]in^2[/tex]

Thus, the area of the square is 64 square inches.

Area of the four circles:

The area of one circle is given by

[tex]A=\pi r^2[/tex]

Substituting r = 2, we have;

[tex]A=4\pi[/tex]

Thus, the area of one circle is 4π in²

The area of 4 circles is 4 × 4π =16π in²

Hence, the area of the 4 circles is 16π in²

Area of the remaining square:

The area of the remaining square is given by

Area = Area of the square - Area of four circles.

Substituting the values, we get;

[tex]Area=64-16\pi[/tex]

Thus, the area of the remaining square is (64 - 16π) in²

Hence, Option c is the correct answer.

Answer:

C. (64 – 16π) in.2

Answer:

you gotta show a picture of the table in order for us to know what's missing from it

When d = -1, the value of y is 300 acres means that the area burned in the fire was 300 acres. When d = -3, the value of y is 1.17 acres means that the area burned in the fire was only 1.17 acres three days

An equation is an expression that shows the relationship between two or more numbers and variables.

we can use the given equation y = (4,800)2^d and substitute the values of d in the table to get the complete table.

Now the equation y = (4,800)2d for d when y = 4,800 and then subtract 7 from that value.

(4,800)2d = 4,800

2d = 1

d = 0.5

The fire had burned for  12 hours, before it measured 4,800 acres.

To determine the area the fire had burned a7 days before this measurement, we will then substitute d = -6.5 into the equation:

y = (4,800)2(-6.5) ≈ 0.00025 acres

The regression equation to predict the number of cans sold on a day that is 90°F will be 871.

A linear system is one in which the parameter in the equation has a degree of one. It might have one, two, or even more variables.

A convenience store manager notices that sales of soft drinks are higher on hotter days, so he assembles the data in the table, shown above. Use technology to find the equation of the least-squares regression line.

Then the regression line will be passing through (55, 340) and (84, 780). Then we have

y - 340 = 15.17(x - 55)

Then the regression equation to predict the number of cans sold on a day that is 90°F will be

y - 340 = 15.17 (90 - 55)

         y = 871

Answer:

Step-by-step explanation:

Given equation:

To solve the equation, the L.H.S must be equivalent to the R.H.S. To prove that L.H.S is equivalent to R.H.S, we have to know the value of "y".

The value of the y variable can be found by isolating the variable from its coefficient. In this equation, the y-variable can be isolated by dividing both sides by four. This cancels the coefficient, isolating the y-variable on one side of the equation.

Once the y-variable has been isolated, we can simplify the other side of the variable. The expression/variable/number obtained, on the other side of the equation, is the value of the y-variable.

Therefore, the value of y is 3.

Answer:

x= 20

Step-by-step explanation:

The total amount of degrees in a triangle is 180. The equation we can pull from this is x+x+30+110= 180. Now we can simplify and combine like terms. x+x= 2x. 30+110 is 140. Now move the constant, 140 to the right. 180-140 is 40. Lastly, divide x and 40 by 2 to get the final answer of 20.

According to the information given, we have that:

a) The system of equations is given by: x + y = 850, 0.5x + 0.75y = 500.

b) You has saved $550 and your sister has saved $300.

A system of equations is when two or more variables are related, and equations are built to find the values of each variable.

In this problem, the variables are:

Item a:

Together you have $850 saved up, hence:

x + y = 850.

You contribute 50% of your savings and your sister contributes 75% of hers toward the $500 cost, hence:

0.5x + 0.75y = 500.

Item b:

From the first equation, we have that:

x = 850 - y

Replacing on the second:

0.5(850 - y) + 0.75y = 500

0.25y = 75

y = 75/0.25

y = 300

x = 850 - y = 550.

You has saved $550 and your sister has saved $300.

Answer:

20 in²

Step-by-step explanation:

Divide the shape into two rectangles (see attached image)

Area of a rectangle = width × length

Area of rectangle 1

⇒ area = 2 × 3

            = 6 in²

Area of rectangle 2

⇒ area = (5 - 3) × 7

            = 2 × 7

            = 14 in²

Total area

Total area = area of rectangle 1 + area of rectangle 2

                 = 6 + 14

When the parents are 2 hours from the house, Bobby will more friends working at the same rate to complete it in 2 hours time.

During this period Bobby and his friends have worked for 2 hours remaining 6 hours.

New rate;

10 person ------> 6 hours
