For triangle ABC, a = 7.7 , b = 17.0 , c = 12.7. Find m∠C.

In order to find any pair of points that have a midpoint of (4, -10), we can choose any two values p and q. Then, one of the endpoints will be (4+p, -10+q) and the other endpoint will be (4-p, -10-q).

For example, let's choose p = q = 2, so we have:

Therefore the ordered pairs (6, -8) and (2, -12) have a midpoint of (4, -10).

Given the equation x+2y=8

When x = -2

When x=0

When x=2

We then plot these points.

Explanation:

Let's see what's the value of the expression if we substitute a = 14:

So definetly Jayden's solution is not correct.

Let's check the second statement: that's what we just did - add the parentheses before dividing. If Jayden would've done that he would have arrieved at the same solution we did, so definetly this statement is false

The third statement could be true. Let's see which value of a gives 8.5 as a result:

If 'a' were 29.75, Jayden would be correct.

Let's see what happens if we divide 14 by 2 and then add 1.5:

This is the result Jayden got, so definetly this is one option for what he did wrong.

Answer:

• Jayden's solution is incorrect: ,true

• Jayden added in the parentheses before dividing:, ,false

• Jayden substituted the wrong value for a: ,true

• Jayden divided 14 by 2 and then added 1.5: ,true

EXPLANATION

The equation x=-13 represents a vertical line.

In order to graph the functiom we need to identify the parent function and the vertical and horizontal shifts that might be done to the function.

In this case we see that the parent function is a cubic function since the greater degree is 3

this means that f(x) is a transformation of g(x)

then

the horizontal shifts since there is sum inside the parentheses the shift will be 1 unit to the left.

the vertical shift will be 1 unit up since there is a sum outside the parentheses.

and finally since there is a - it means that the function is reflected over the x-axis

the parent function will be the red line and the function #15 is the blue line.

In order to find points we can tabulate the values for given xs' and construct the graph.

Start by making a table like this:

now since the function is given we can replace x with the values and find y

then after tabulating values should look like this

Now looking at the graph on the blue function we can see that the function is decreasing until reaching x=-1, however after that the function will continue to decrease but at a different rate, which means that over the interval

the function will be decreasing

The length of every closed shape's perimeter is its whole perimeter. This rectangular farm has two sides, with l being the bigger side and b being the smaller side. His farm's circumference may be calculated by adding the lengths of its four sides. Total distance = 2l + 2b (l + b + l + b). In light of this, a rectangle's perimeter is equal to 2 (l + b) units. The complete distance around a shape is referred to as its perimeter. It is any two-dimensional geometric shape's perimeter or outline length. Depending on the measurements, the perimeter of multiple figures may be equivalent. Consider a triangle that is constructed from an L-length wire as an example.

Step-by-step explanation:

Ally has a square backyard with an area of 169 square feet.

Given a square of side length, s

Therefore:

Therefore, the length of one side of the backyard is 13 feet.

Let:

y=2x+18 (1)

4x+5y=20 (2)

replace (1) into (2)

4x+5(2x+18)=20

Using distributive property:

4x+10x+90=20

Add like terms:

(4x+10x)+90=20

14x+90=20

subtract 90 from both sides:

14x+90-90=20-90

14x=-70

Divide both sides by 14:

14x/14=-70/14

x=-5

Finally, replace the value of x into (1)

y=2(-5)+18

y=-10+18

y=8

Let:

2x+2y=6 (1)

3x-5y=25 (2)

From (1) let's solve for x:

subtract 2y from both sides:

2x+2y-2y=6-2y

2x=6-2y

Divide both sides by 2:

x=(6-2y)/2

x=3-y (3)

Replace (3) into (2)

3(3-y)-5y=25

Using distributive property:

9-3y-5y=25

Add like terms:

9+(-3y-5y)=25

9-8y=25

subtract 9 from both sides:

9-8y-9=25-9

-8y=16

Divide both sides by -8:

(-8y)/(-8)=(16)/(-8)

y=-2

Finally, replace the value of y into (3)

x=3-(-2)

x=3+2

A 56-inch board is to be cut into three pieces so that the second piece is 3 times as long as the first piece and the third piece is 4 times as long as the first piece. The length of all the three pieces are : 7, 21, 18.

There are 3 pieces:

Length of first piece = x

Length of second piece = 3x

Length of third piece = 4x

Total length = 8x

Now, 8x = 56

Divide both side by 8x

x = 56 /8

x = 7

Length of second piece = 3x where x = 7

3x = 3 ( 7)

=  21

Length of third piece = 4x where x = 7'

4x = 4 ( 7)

=  28

Therefore we can conclude that the length are : 7, 21, 18.

Step-by-step explanation:

y=−6x+5−2x+y=5

Hope this helps.

When two planes  which are 2505 miles apart and fly toward each other. if their speeds differ by 85mph and If they pass each other in 3 hours, then the speed of first plane is 372.5 mph and the speed of second plane is 462.5 mph

Their speeds differ by 85mph

Consider the speed of first plane = x mph

The speed of second plane = 90+x mph

The relative speed = sum of both speed

= x + x+90

= 2x+90 mph

The distance between the planes = 2505 miles

Time taken to pass each other = 3 hours

Therefore in 3 hours

3(2x+90) = 2505

6x+270 = 2505

6x = 2505-270

6x = 2235

x = 2235/6

x = 372.5 mph

The speed of second plane = 90+x

= 90+372.5

= 462.5 mph

Hence, when two planes  which are 2505 miles apart and fly toward each other. if their speeds differ by 85mph and If they pass each other in 3 hours, then the speed of first plane is 372.5 mph and the speed of second plane is 462.5 mph.

In order to determine the total area of the sign, we need to calculate the area of the triangle, and the area of the semicircle. The expressions we need to use are described below:

We were given the diameter of the semicircle, it's radius is half of the diameter, therefore:

The base of the triangle is equal to the diameter of the semicircle. With this we can calculate both areas:

The total area of the figure is the sum of the above, therefore:

The area is approximately 50 in². The correct option is J.

Remember that a difference of squares can be written as the product of two conjugate binomials:

In the given expression, notice that m^4 and n^4 can be written as (m^2)^2 and (n^2)^2:

Once written as a difference of squares, we can factor the expression:

Therefore:

The quadratic function in standard form is g(x)= x²-10x+0

Quadratic functions are polynomial functions of the second degree, meaning they contain at least one squared term.

Quadratic functions are another name called quadratics. The quadratic function has the following general form: f(x)=ax² + bx + c.

An quadratic function is given as g(x)= x²-10x

In the standard form of the quadratic equation, there should be three terms, terms with power two, one and a constant.

In the given equation, there is a constant term missing.

So, we add a zero to the end because it brings no change to the function quantitatively.

So, the standard form of the given quadratic function will be g(x)= x²-10x+0
