The computation of triangle ABC and ACD which are both isosceles shows that the value of x will be 36°.

It should be noted that the sum of angles in a triangle is 180°. In this situation two of the three angles have been given.

Therefore, the value of the third angle will be:

86° + 58° + x = 180°

144° + x = 180°

x = 180° - 144°

x = 36°

In conclusion, x is 36°.

Answer:

D  5y + 29x = 500

Step-by-step explanation:

Slope-intercept form of a linear equation:  y = mx + b

(where m is the slope/rate of change, and b is the y-intercept)

Given:  

⇒ when x = 0, y = 100

Therefore,  b = 100

Given:

Note that the water is decreasing in volume as time goes by.  Therefore, the rate of change is negative, so m = -5.8

Inputting these values into the equation gives:

y = -5.8x + 100

Multiply the equation by 5:

5y = -29x + 500

Rearrange:

5y + 29x = 500

Therefore, D is the solution.

ac - ad - bc + bd

Step-by-step explanation:

There aren't very many steps to show, but I'm assuming that you needed to multiply out the equation. So for this, you would use FOIL which means first, inner, outer, last.

I think of it as multiplying the a with c and d, and then multiplying the b with the c and d. When you do this, you get ac - ad - bc + bd.

Answer:

The inverse is  5±sqrt(x+25)

Step-by-step explanation:

y = x^2 - 10x

To find the inverse, exchange x and y and solve for y

x = y^2 -10y

Complete the square

x+25 = y^2 -10y +25

x+25 = (y-5)^2

Take the square root of each side

±sqrt(x+25) = y-5

Add 5 to each side

5±sqrt(x+25) = y

The inverse is  5±sqrt(x+25)

Answer:

[tex]y=\pm\sqrt{x+25}+5[/tex]

Step-by-step explanation:

Given function:

[tex]y=x^2-10x[/tex]

Rearrange to make [tex]x[/tex] the subject.

First, complete the square by adding 25 to both sides and factoring:

[tex]y+25=x^2-10x+25[/tex]

[tex]y+25=(x-5)^2[/tex]

Square root both sides:

[tex]\pm\sqrt{y+25}=x-5[/tex]

Add 5 to both sides:

[tex]x=\pm\sqrt{y+25}+5[/tex]

Finally, swap [tex]x[/tex] and [tex]y[/tex] (since the inverse of a function is its reflection in the line [tex]y = x[/tex])

[tex]y=\pm\sqrt{x+25}+5[/tex]

Answer:

75 feet

Step-by-step explanation:

[tex]\frac{2.5ft}{1in} = \frac{x}{30in} \\[/tex]

By using a proportion we can solve this problem.

By isolating x we get x = 2.5(30) so x = 75.

Thus if the wall is 30 in in the model it is 75 feet in actuality.

The lines in the graph are pretty close to each other, the answer would be the second choice.

The value of k in the function f(x) = 2x-k is 6.

Function is a type of relation, or rule, that maps one input to specific single output.

In mathematics, a function is an expression, rule, or law that describes the relationship between one variable (the independent variable) and another variable (the dependent variable) (the dependent variable). In mathematics and the physical sciences, functions are indispensable for formulating physical relationships.

Linear function is a function whose graph is a straight line

We are given that;

f(x) = 2x + 4

f(x) = 2x-k

Now,

To shift a linear function to the right, we subtract a constant from the input variable x. For example, f (x) = 2x + 4 shifts to the right by 2 units when it is replaced with f (x) = 2 (x - 2) + 4.

In this case, f (x) = 2x + 4 shifts six units to the right when it is replaced with f (x) = 2 (x - k) + 4. To find the value of k, we can equate the expressions inside the parentheses and solve for k:

x - k = x - 6 k = 6

Therefore, by the given functions the answer will be 6.

Answer:

Slope: -34

Point: (4, -3)

Step-by-step explanation:

This equation is written in point-slope form. The equation of a line in point-slope form is written as (y - y_1) = m(x - x_1).

We are asked to find the point and slope of (y + 3) = -34(x - 4). We can automatically determine that the slope is -34 because that's where the variable, m, is. Next, we know that the x-coordinate is 4 because it's in the place of x_1. Lastly, the y-coordinate is -3 because it changes the subtraction sign to an addition sign, and it's in the place of y_1. Thus, the point would be (4, -3).

Step-by-step explanation:

180 - 110 (y) = 70

so corner b = 70 degrees

70 + 78 = 148

180 - 148 = 32

180 because all triangles angles add up to 180 degrees
