Answer:

C

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = - 2 and c = 8, then

y = - 2x + 8 → C

Answer:

(x - 3)² + (y + 1)² = 65

Step-by-step explanation:

The equation of a circle in standard form is

(x - h)² + (y - k)² = r²

where (h, k) are the coordinates of the centre and r is the radius

The centre C is at the midpoint of the endpoints of the diameter.

Using the midpoint formula to find C

C = ( [tex]\frac{7-1}{2}[/tex], [tex]\frac{6-8}{2}[/tex] ) = ( [tex]\frac{6}{2}[/tex], [tex]\frac{-2}{2}[/tex] ) = (3, - 1 )

The radius is the distance from the centre to either of the endpoints of the diameter.

Using the distance formula to find r

with C (3, - 1 ) and (7, 6 ) , then

r = [tex]\sqrt{(7-3)^2+(6+1)^2}[/tex]

  = [tex]\sqrt{4^2+7^2}[/tex]

  = [tex]\sqrt{16+49}[/tex]

  = [tex]\sqrt{65}[/tex]

Then equation of circle is

(x - 3)² + (y - (- 1) )² = ([tex]\sqrt{65}[/tex] )², that is

(x - 3)² + (y + 1)² = 65 ← equation of circle

Answer: y = 2 when x = 4

i looked for a correlation in the given problem, and i realized that "y" will equal half of whatever "x" equals. so when x = 4, y = 2.

Answer:

(-4 , 8)

Step-by-step explanation:

The x-axis is the horizontal line. In this case, if you are reflecting over the x-axis, you are flipping the sign of the y-coordinate.

Same with the y-axis. If you are reflecting over the y-axis, you are flipping the sign of the x-coordinate.

In this case, reflect across the x-axis. Flip the sign of the y: (x , y)

(-4 , -8) reflected over the x-axis is (-4 , 8).

Vineisha earned 110 percent on the science quiz which was about the phases of the moon.

Vineisha earned 22 out of 20 points on her science quiz over the phases of the moon

The percent earned can be calculated by dividing 20 by 22 and then multiplying the result by 100

22/20 × 100

= 1.1 × 100= 110

Hence the percent she earned on the quiz is 110%

Step-by-step explanation:

Answer: Her grandfather deposited $4480 on Dolores's  eighteenth birthday.

Step-by-step explanation:

Initial amount deposited = $35 (on tenth birthday)

Amount deposited after a year  = 2 x ($35)  (on eleventh birthday)

Amount deposited after 2 years  =2 x( 2 x ($35))  = 2²(35)(on eleventh birthday)

It is following the geometric progression, where a= 35, r= 2 (common ratio)

nth term in GP =[tex]ar^{n-1}[/tex]

Amount deposited on eighteenth birthday (i.e. n=8) = [tex](35)(2)^{8-1}[/tex]

[tex]=35\times2^7=35\times128=4480[/tex]

Hence, Her grandfather deposited $4480 on Dolores's  eighteenth birthday.

Answer:

x= 1

y- 5

Step-by-step explanation:

okay so you know the rules...

we need to eliminate one variable to solve this system so first...

im going to get rid of x first to do so i need to...

multiply any of the equation by negative one to get it to a positive to eliminate

-2x - 5y= -27

( -2x + 3y= 13) -1

-2x -5y= -27

2x -3y= -13   follow the rules of signed integers

we eliminate x and have this left

-5y= -27

-3y= -13    use the second rule of elimination....add the rest up

-8y= -40   divide both sides by -8

y= 5

we arent done yet we need to find the other variable

plug in y to one of the equations like this...

-2x - 5(5)= -27

-2x - 25= -27   add -25 to both sides to get the variable by itself

-2x= -2   divide both sides by -2

x= 1

Answer:

n = -5

Step-by-step explanation:

Solve for n:

n + 2 = 4 n + 17

Hint: | Move terms with n to the left hand side.

Subtract 4 n from both sides:

(n - 4 n) + 2 = (4 n - 4 n) + 17

Hint: | Combine like terms in n - 4 n.

n - 4 n = -3 n:

-3 n + 2 = (4 n - 4 n) + 17

Hint: | Look for the difference of two identical terms.

4 n - 4 n = 0:

2 - 3 n = 17

Hint: | Isolate terms with n to the left hand side.

Subtract 2 from both sides:

(2 - 2) - 3 n = 17 - 2

Hint: | Look for the difference of two identical terms.

2 - 2 = 0:

-3 n = 17 - 2

Hint: | Evaluate 17 - 2.

17 - 2 = 15:

-3 n = 15

Hint: | Divide both sides by a constant to simplify the equation.

Divide both sides of -3 n = 15 by -3:

(-3 n)/(-3) = 15/(-3)

Hint: | Any nonzero number divided by itself is one.

(-3)/(-3) = 1:

n = 15/(-3)

Hint: | Reduce 15/(-3) to lowest terms. Start by finding the GCD of 15 and -3.

The gcd of 15 and -3 is 3, so 15/(-3) = (3×5)/(3 (-1)) = 3/3×5/(-1) = 5/(-1):

n = 5/(-1)

Hint: | Simplify the sign of 5/(-1).

Multiply numerator and denominator of 5/(-1) by -1:

Answer: n = -5

Concept: Modeling expressions

The height of the object that falls after 0.75 seconds given that t is represented in seconds is 191 feet.

A quadratic equation is the second-order degree algebraic expression in a variable. the standard form of this expression is  ax² + bx + c = 0 where a. b are coefficients and x is the variable and c is a constant.

The expression 200 - 16t^2 models the height in feet of an object that falls from the initial height of 200 feet t seconds after being dropped.

We need to find the time after 0.75 seconds given that t is represented in seconds.

The expression is given

[tex]200 - 16t^2[/tex]

time t = 0.75

Substitute the value of t in the given expression

= 200 - 16(0.75)^2

= 200 - 9

= 191

Hence we get the answer to 191 feet.
