The vertex of the quadratic function y = x² + 10x + 24 is located at point B. (-5, -1). This is found by using the formula -b/2a for the x-coordinate and substituting the x coordinate into the function for the y-coordinate.

The vertex of a quadratic function (a function in the form of y=ax²+bx+c) is the point that represents the minimum or maximum of the function graph. In this case, we are looking to find the vertex of the function y = x² + 10x + 24. The formula to find the x-coordinate of the vertex of a quadratic function is -b/2a. In this function, a = 1 and b = 10, giving us -10/(2*1) = -5 for the x-coordinate of vertex. We then substitute -5 into the function for x to determine the y-coordinate, resulting in y = (-5)² + 10*-5 + 24 = -1. Therefore, the vertex of the function is (-5,-1). So, the correct choice is B. (-5, -1).

Answer: [tex]80 in^2[/tex]

Step-by-step explanation:

The area of a parallelogram can be calculated with the following formula:

[tex]A=b*h[/tex]

Where "b" is the base and "h" is the height or altitude.

You know that the base of  this parallelogram  is 8 inches long and the altitude to the base is 10 inches, then:

[tex]b=8in\\h=10in[/tex]

You need to substutite these values into the formula.

Therefore, the area the parallelogram is:

[tex]A=(8in)(10in)\\\\A=80in^2[/tex]

Answer:

Answer:

53

Step-by-step explanation:

Let's make some equations.

The number is two-digit, so let's make it [tex]xy[/tex]

Also, the two digits add up to 8, so [tex]x+y=8[/tex]

Now the value of [tex]xy=10x+y[/tex]

and the value of [tex]yx=10y+x[/tex]

Since we know that when we reverse the digits the number is less than the resulting number by 18, we can formulate an equation.

[tex]10y+x=10x+y+18[/tex]

Solve this equation.

[tex]9y-9x=18[/tex]

[tex]9(y-x)=18[/tex]

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

Now let's use the equation we made earlier.

Change [tex]x+y=8[/tex] into [tex]y=8-x[/tex]

Solve the system of equations.

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

[tex]y=8-x[/tex]

[tex]8-x-x=2[/tex]

[tex]8-2x=2[/tex]

[tex]-2x=-6[/tex]

[tex]x=3[/tex]

[tex]y-3=2[/tex]

[tex]y=5[/tex]

So the original number is 53.

This is just m anglex=.5(58+22)=.5(80)=40

Answer:

x = 40

Step-by-step explanation:

When 2 chords intersect inside a circle then the measure of the angle formed is half the sum of the arcs intercepted by the angle and it's vertical angle, so

x = 0.5(58 + 22)° = 0.5 × 80° = 40°

Answer:

[tex]n=5[/tex]

Step-by-step explanation:

We have the following expression [tex]\frac{2}{8} = \frac{n}{20}[/tex] and we must solve for variable n.

To solve the equation multiply by 20 on both sides of the equality and you will get the following

[tex]20*\frac{2}{8} = 20*\frac{n}{20}[/tex]

[tex]\frac{20*2}{8} = \frac{20n}{20}[/tex]

[tex]\frac{40}{8} = n[/tex]

[tex]n= \frac{40}{8}[/tex]

Finally we have that:

[tex]n=5[/tex]

Answer:

n=5

Step-by-step explanation:

2/8 = n/20

Using cross products

2 * 20 = 8*n

40 = 8n

Divide each side by 8

40/8 = 8n/8

5 =n

Answer:

First car:  35 gallons

Second car: 15 gallons

Step-by-step explanation:

Assuming [tex] x [/tex] to be the gas consumed by 1st car and [tex] 50 - x [/tex] to be the gas consumed by 2nd car.

We know that:

Distance traveled = fuel efficiency × gas consumed

[tex]20x+35(50-x)=1225[/tex]

[tex]20x+1750-35x=1225[/tex]

[tex]35x-20x=1750-1225[/tex]

[tex]15x=525[/tex]

[tex]x=35[/tex]

So [tex]50 - x = 50-35=15 [/tex]

Therefore, first car consumed 35 gallons while second car consumed 15 gallons.

Answer:

First car: 35 gallons

Second car: 15 gallons

Step-by-step explanation:

Set up a system of equations.Let be "x" the number of gallons consumed by the first car and "y" the number of gallons consumed by the second car.

Then:

[tex]\left \{ {{x+y=50} \atop {20x+35y=1,225}} \right.[/tex]

Applying the Elimination method, multiply the first equation by -20, then  add both equations and solve for "y":

[tex]\left \{ {{-20x-20y=1,000} \atop {20x+35y=1,225}} \right. \\.......................\\15y=225\\y=15[/tex]

Substitute this value into the first equation and solve for "x":

[tex]x+15=50\\x=35[/tex]

Last option: 7

Step-by-step explanation:

The Standard form of a quadratic equation is the following:

[tex]ax^{2}+bx+c=0[/tex]

Where "a" is the quadratic coefficient (This coefficient cannot be 0), "b" is the linear coefficient, "c" is the constant and "x" is the variable.

In this case you have the quadratic equation [tex]3x^2 + 5x + 7 = 0[/tex] which is written is Standarf form. Then, you can identify that:

[tex]a=3\\b=5\\c=7[/tex]

Therefore the value of "c" is 7.

Answer:

B. [tex]x=3,\ y=20,\ z=-14[/tex]

Step-by-step explanation:

Consider the system of three equations:

[tex]\left\{\begin{array}{l}2x+2y+3z=4\\5x+3y+5z=5\\3x+4y+6z=5\end{array}\right.[/tex]

Multiply the first equation by 5, the second equation by 2 and subtract them:

[tex]\left\{\begin{array}{r}2x+2y+3z=4\\4y+5z=10\\3x+4y+6z=5\end{array}\right.[/tex]

Multiply the first equation by 3, the second equation by 2 and subtract them:

[tex]\left\{\begin{array}{r}2x+2y+3z=4\\4y+5z=10\\-2y-3z=2\end{array}\right.[/tex]

Multiply the third equation by 2 and add the second and the third equations:

[tex]\left\{\begin{array}{r}2x+2y+3z=4\\4y+5z=10\\-z=14\end{array}\right.[/tex]

Fro mthe third equation

[tex]z=-14[/tex]

Substitute it into the second equation:

[tex]4y+5\cdot (-14)=10\\ \\4y=10+70\\ \\ 4y=80\\ \\y=20[/tex]

Substitute y=20 and z=-14 into the first equation:

[tex]2x+2\cdot 20+3\cdot (-14)=4\\ \\2x+40-42=4\\ \\2x-2=4\\ \\2x=6\\ \\x=3[/tex]

The solution is

[tex]x=3,\ y=20,\ z=-14[/tex]

Final answer:

Jonathan's weekly income is determined by a linear function M(h) = 9.5h + 25, with the domain being 0 ≤ h ≤ 20 to reflect his work hour limitations. A sketch of this function would show a linear increase from an initial allowance of $25, rising by $9.50 for each hour worked up to 20 hours.

Explanation:

Jonathan makes a weekly allowance of $25 and earns $9.50 per hour at his job, with a maximum work limit of 20 hours per week.

a) Function for Jonathan's weekly earnings:

The function M(h) = 9.5h + 25 represents the amount of money Jonathan makes each week, where h is the number of hours he works.  

b) Domain of the function:

The domain of this function, considering Jonathan's work hour limitation, is 0 ≤ h ≤ 20. This range is because Jonathan cannot work more than 20 hours a week due to his age restrictions.

c) Sketch of the graph:

The graph would start at the point (0, 25), which represents Jonathan's weekly allowance without any worked hours. Then, it would rise linearly at a slope of $9.50 for each additional hour worked, up to the point (20, 215), which represents the maximum amount Jonathan can earn by working 20 hours plus his weekly allowance. Note: The actual graph is not displayed here but can easily be sketched using the described points and slope.

put the values into the equation

Let

[tex]P1(-3,-1) \\P2(5,1)\\\\m=\frac{y_{2}-y_{1} }{x_{2}-x_{1} } \\m=\frac{1-(-1)}{5-(-3) } \\m=\frac{1+1}{5+3} \\m=\frac{2}{8} \\m=\frac{1}{4}[/tex]

Answer:

D) (the fourth one)

Step-by-step explanation:

The function will never go below 0 since the absolute of a negative number is a positive number, so C is out of the question.

The equation of an absolute function is f(x) = a|x-h|+k

h is the offset on the x axis, and the equation of this function is |x-(1)|, so that means the function is shifted one to the right, making it D.

Answer: Area: 256 ft squared   Perimeter: 64 feet

Step-by-step explanation: If the scale is 1 cm to 8 ft then if you multiply 1 cm by 2 you get 2 cm. Then you multiply 8 by 2 to get 16 feet. Once you get 16 feet, you can do 16 times 16 to find the area and 16 times 4 to find the perimeter.

Answer:

Their point of intersection will always be on the line y = x.

Step-by-step explanation:

We have a function f(x) and its inverse is the function f⁻¹(x).

The domain and range of a function replaces each other for the inverse of that function.

So if f(x) and f⁻¹(x) are inverse of each other

and f(a) = b

then a = f⁻¹(b)

Another example to make it clear is that

f(5) = 25

f⁻¹(25) = 5

The function and its inverse will intersect each other at the point where f(x) = f⁻¹(x) which is only possible when a = b.

Hence, a function and its inverse will always intersect at a point on the line x=y.

Answer:

[tex]slope =\frac{1}{4}[/tex]

slope is undefined

Step-by-step explanation:

WE need to find the slope of two lines

to find out slope we use formula

[tex]slope =\frac{y_2-y_1}{x_2-x_1}[/tex]

To find slope we pick two points from the line

(-4,0) and (0,1) is (x1,y1) and (x2,y2)

[tex]slope =\frac{1-0}{0+4}=\frac{1}{4}[/tex]

[tex]slope =\frac{1}{4}[/tex]

To find slope we pick two points from the line

(1,0) and (1,1) is (x1,y1) and (x2,y2)

[tex]slope =\frac{1-0}{1-1}=\frac{1}{0}[/tex]

When denominator =0 then the slope is undefined
