Answer:

No. This is not a function

Step-by-step explanation:

8 and 9 have more than one relationship with another number which describes it as not being a function.

Answer:

Step-by-step explanation:

y = -4x - 8

Any equation with an equal slope will be parallel to the line

Example: y = -4x or y = - 4x + 8

As long as the equation has a different y-intercept and equal slope it will be parallel!

An equation of a line that is parallel to y = -4x - 8 would be in the form:

y = -4x + b

In mathematics, the equation of a line is a formula that describes the relationship between the x and y coordinates of the points on the line.

Two lines are parallel if they have the same slope. The equation of the line y = -4x - 8 is in slope-intercept form, y = mx + b, where m is the slope and b is the y-intercept.

From y = -4x - 8, we can see that the slope is -4. So, any line that is parallel to this line must also have a slope of -4.

Therefore, an equation of a line that is parallel to y = -4x - 8 would be in the form:

y = -4x + b

Where b is some constant value that determines the y-intercept of the line.

Answer:

1.5

Step-by-step explanation:

Vertical angles are congruent so:

7x=8x-12

Subtract 7x from both sides:

0=8x-12

Add 12 to both sides:

8x=12

Divide both sides by 8:

x=1.5 or

x= 3/2

Answer:

Solving the equations we get: x = -3, y = 4

The solution set is: (-3,4)

Step-by-step explanation:

We need to solve the system of equation and find value of x and y

The system of equation given is:

[tex]y = -x + 1\\y = -2x - 2[/tex]

Let:

[tex]y = -x + 1--eq(1)\\y = -2x - 2--eq(2)[/tex]

We would use substitution method.

Put value of y from eq(1) into eq(2) and find value of x

[tex]Eq(2)\;is:\\y=-2x-2\\Put\:y=-x+1\\-x+1=-2x-2\\-x+2x=-2-1\\x=-3[/tex]

So, we get x = -3

Now, for finding value of y, put value of x = -3 into equation 1

[tex]y=-x+1\\Put\:x=-3\\y=-(-3)+1\\y=3+1\\y=4[/tex]

So, we get y=4

Solving the equations we get: x = -3, y = 4

The solution set is: (-3,4)

Step-by-step explanation:

The required, simplified expression is -27/64 * p³, as of the given expression

Simplify the expression: (-3/4p)³

To simplify, we raise the expression to the power of 3:

(-3/4p)³ = (-3/4p) * (-3/4p) * (-3/4p)

Simplifying further:

(-3/4)³ * (p³) = -27/64 * p³

Therefore, the simplified expression is -27/64 * p³,  as of the given expression.

Answer:

B: (x + 1) = (y - 2)²

Step-by-step explanation:

0 = y² - x - 4y + 3

We want to find the equation of the parabola in vertex form.

The format for the vertex form is;

y = a(x - h) + k

Where (h, k) is the coordinate of the vertex.

Thus, let's transform 0 = y² - x - 4y + 3 into the vertex form

Let's rearrange to get;

x - 3 = y² - 4y

Let's use method of completing the square to get right hand side;

x - 3 = (y - 2)² - 4

Add 4 to both sides to get;

x - 3 + 4 = (y - 2)²

(x + 1) = (y - 2)²

Answer:

357 minutes

Step-by-step explanation:

I subtracted 9 cents/minute from the 23 cents/minute to get 14 cents to get the difference between the two per minute charges.  I then divided the monthly cost of $49.95 by .14 to get 356.79...  So if you used 357 minutes in a month, the second plan would be 3 cents cheaper at $82.08 (.09 x 357= 32.13 + 49.95), vs. the first plan costing $82.11 (.23 x 357).  At 356 minutes the first plan would still be cheaper.

Step-by-step explanation:

The answer would be the first one, combining 8 and -2

This is because the 2 like terms are 8x^2 and -2x^2. You can get this by looking in the problem. There are 2 terms with x^2 which means we have to combine them. One of them is 8x^2 (the 1st one) and the other is -2x^2 (since it says 7-2x^2)

If you combine these you will get 6x^2 [8+(-2)=6]

Step-by-step explanation:

Let x be the number of buses for the trip.

Then (32 - x) is the number of cars for the trip.

We have 27x + 3(32 - x) = 408.

=> 27x + 96 - 3x = 408

=> 24x = 312

=> x = 13

Hence there are 13 buses and (32 - 13) = 19 cars.

Answer:

m = 0

Step-by-step explanation:

1/2(-1.4m+0.4)=m+0.2

We move all terms to the left:

1/2(-1.4m+0.4)-(m+0.2)=0

Domain of the equation: 2(-1.4m+0.4)!=0

m∈R

We get rid of parentheses

1/2(-1.4m+0.4)-m-0.2=0

We multiply all the terms by the denominator

-m*2(-1.4m+0.4)-(0.2)*2(-1.4m+0.4)+1=0

Wy multiply elements

-2m^2(--(0.2)*2(-1.4m+0.4)+1=0

We use the square of the difference formula

-2m^2(+(0.2)*2(-1.4m+0.4)+1=0

Echelon form of augmented matrix      [tex]\left[\begin{matrix} 2&3&-5&b_1\\0&\frac{47}{2} &\frac{101}{2} &b_2-\frac{17}{2}b_1 \\0&0&\frac{-10}{3} &b_3-2\frac{b_1}{6} \end{matrix}\right][/tex]

Step-by-step explanation:

We have, linear systems

[tex]2x_1+3x_2-5x_3=b_1[/tex]

[tex]17x_1+2x_2+8x_3=b_2[/tex]

[tex]-x_1+x_2-5x_3=b_3[/tex]

[tex](a)[/tex]  Find the echelon form of the augmented matrix.

Firstly we find the augmented matrix (A) of the given linear system

[tex]A=\left[\begin{matrix} 2&3&-5&b_1\\17&2&8&b_2\\-1&1&-5&b_3\end{matrix}\right][/tex]

Now find the echelon form

[tex]=\left[\begin{matrix} 2&3&-5&b_1\\0&\frac{47}{2} &\frac{101}{2} &b_2-\frac{17}{2}b_1 \\0&\frac{5}{2} &\frac{-15}{2} &b_3+\frac{b_1}{2} \end{matrix}\right]^{R_2\rightarrow \frac{17}{2}R_1, R_3\rightarrow R_3+\frac{1}{2}R_1 }[/tex]

[tex]=\left[\begin{matrix} 2&3&-5&b_1\\0&\frac{47}{2} &\frac{101}{2} &b_2-\frac{17}{2}b_1 \\0&0&\frac{-10}{3} &b_3-2\frac{b_1}{6} \end{matrix}\right]^{R_2\rightarrow R_3-\frac{5}{6}R_1 }[/tex]

[tex](b)[/tex]  From above echelon form of augmented matrix system is consistent .

So, system has always a solution exist for every condition of [tex]b_1,b_2, b_3[/tex]

[tex](c)[/tex]  Yes, If we take point  [tex](0,1,1)[/tex] then system of linear equation has exist a solution.

[tex](d)[/tex]   yes, if pick randomly [tex]b_1,b_2, b_3[/tex] then always exist a solution of given system of linear equation.
