Answer:

15 I think.

Step-by-step explanation:

If the perimeter is 42 inches and the width is 6 inches. That is only one side so you multiply.6 by 2 to get 12. Then 42 minus 12 is 30. Finally you split 30 into 2, to get the length. Since there are to sides. So 15.

The  exponential function has an x-intercept should be considered as the option A. F(x) = 100+-5-1.

It is the mathematical function that should be denoted by f(x)=\exp or [tex]e^{x}[/tex]. It defined the positive valued function with respect to the real variable. Also, it could be extended to the numbers that are complex or could be general to the other maths objects.

hence, The  exponential function has an x-intercept should be considered as the option A. F(x) = 100+-5-1.

Answer:

Undefined slope

Step-by-step explanation:

To calculate the slope between two points, you divide the difference of the y-coordinates of 2 points on a line by the difference of the x-coordinates of those same 2 points.

The formula for the slope m between points (x₁, y₁) and (x₂, y₂) is: [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex] , which is also known as "rise over run".

Here, we have the points (-9, 3) and (-9, 2).

x₁ = -9,  y₁ = 3,  x₂ = -9,  y₂ = -2. We can plug these values in to the "rise over run" equation:

[tex]m=\frac{-2-3}{-9-(-9)}[/tex]

[tex]m=\frac{-5}{0}[/tex]

This is a vertical line.

The slope of a line cannot be undefined (a vertical line), because the x-coordinate never changes no matter what the y-coordinate is. Thus, the slope is undefined for the line passing between these two points.

Answer: y = 1/4x - 4

Step-by-step explanation: write it in slope intercept form y = mx + b

Answer: I think it would be 1/52

Step-by-step explanation:

As you said, we can solve this system for y by using substitution.

[tex]x = 2y - 6\\y = 3x - 7\\\\y = 3(2y - 6) - 7\\\\y = 6y - 18 - 7\\\\y = 6y - 25\\\\-5y = -25\\\\y = 5[/tex]

Now, using what we got for y, we plug it into one of the original equations to solve for x.

[tex]x = 2(5) - 6\\\\x = 10 - 6\\\\x = 4[/tex]

Now we have the solution of this system.

[tex](4, 5)[/tex]

For the given equations x=2y-6 and y=3x-7 the value of x is 4 and the value of y is 5.

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that the two equations are x=2y-6 and y=3x-7. The value of x and y will be calculated as,

x=2y-6

y=3x-7

Solve the above equations by substitution method,

x=2(3x-7)-6

x = 6x -14 - 6

6x - x = 20

5x = 20

x = 4

The value of y will be calculated as,

y=3x-7

y = ( 3 x 4) - 7

y = 12 - 7

y = 5

Step-by-step explanation:

The area of a triangle is base times height divided by two. Your base, which happens to be on top, goes from -4 to 3, or 7 units. The height goes from 3 to -3, or 6 units. 6 times 7 is 42, and 42/2= 21

Answer:

m∠XYZ = 162°

Step-by-step explanation:

We can see that ∠XYZ is an exterior angle while ∠W and ∠X are the opposite interior angles.

We know that the exterior angle of triangle is equal to the sum of opposite interior angles

Given

m∠XYZ = (15x-18)°

m∠W = (5x+2)°

m∠X = (8x+4)°

Mathematically it can be written as:

m∠X+m∠W = m∠XYZ

[tex]8x+4+5x+2 = 15x-18\\13x+6 = 15x-18\\13x-15x = -18-6\\-2x = -24\\\frac{-2x}{-2} = \frac{-24}{-2}\\x = 12[/tex]

Putting x=12 in m∠XYZ

[tex]15x-18\\=15(12)-18\\=180-18=162[/tex]

Hence,

m∠XYZ = 162°

Using the half angle identity:

[tex]\sin\left(\frac{x}{2}\right)+\cos\left(x\right)-1=0\\\sin\left(\frac{x}{2}\right)+1-2\sin^{2}\left(\frac{x}{2}\right)-1=0\\\sin\left(\frac{x}{2}\right)-2\sin^{2}\left(\frac{x}{2}\right)=0\\\sin\left(\frac{x}{2}\right)\left(1-2\sin\left(\frac{x}{2}\right)\right)=0\\[/tex]

Using zero product rule:

[tex]\sin\left(\frac{x}{2}\right)=0,\frac{1}{2}\\x=\frac{x}{2}=0,30,150,180\\x=0,60,300,360[/tex]
