Find the difference: -4- (-3) =

Answer:

The student took 28 classes

Step-by-step explanation:

What I did was minus $15 from the $687 total, cause $15 is only a one time registration fee, then 687-15=672, so then I divided 672 by the cost per class, so $24, 672 divided by 24 equals to 28, so the student took 28 classes.

Answer:

- The equation that represent the cost C of renting a car and driving x miles is C = $39.11 + $0.50x

- $130 can travel 181.32 miles

Step-by-step explanation:

From the question, a rental company rents a luxury car at a daily rate of 39.34 ​$ plus​ $.50 per mile, that is

$0.50 is added to the initial $39.34 for every mile.

The equation that represent the cost C of renting a car and driving x miles is

C = $39.34 + $0.50x

Now, to determine how many miles 130$ can travel,

we will put C = $100, and determine x in the above equation

$130 = $39.34 + $0.50x

$130 - $39.34 = $0.50x

$90.66 = $0.50x

x = $90.66/$0.50

x = 181.32

Hence, $130 can travel 181.32 miles

so when you divide 5/8 you get 0.625 and rounding it of to the nearest whole number it will be 1.

hope this helps

Answer:

1

Step-by-step explanation:

(8/8) = 1                                 (4/8) = half                       (0/8) = 0

                                   (5/8) = a bit more than half, so is closer to 1

5/8≈1

6c + (c - 7) + (9c - 8) + (4c + 6) =

Answer:

1

Step-by-step explanation:

you should remove 8 out of 10 then 2 will remain

then add negative 5 to both sides then we will left with -3x = -3

divide -3 on both sides we find x = 1

Answer:

x=1

Step-by-step explanation:

-3x + 5= -8 + 10​

Combine like terms

-3x+5 = 2

Subtract 5 from each side

-3x+5-5 = 2-5

-3x = -3

Divide by -3

-3x/-3 = -3/-3

x =1

Answer and Step-by-step explanation:

When making a perpendicular line, you take 2 points on a straight line.

- You put the compass on the two points, making marks above and below to be able to draw the line.

When making an angle bisector line, you use the angle and 2 points to make a straight line that will bisect the angle.

- You put the compass on the angle, making an arc from the two lines that join to make the angle. Then, you put your compass on where the arc meets the lines, and make a mark, which you then draw a line through.

Answer:

w= 59/5 or 11.8

Step-by-step explanation:

-3(w+4)+8(w-6)=1/2(18-20)

-3w-12+8w-48=9-10

5w-60=-1

5w=-1+60

5w=59

w=59/5

Answer:

x = 11

Step-by-step explanation:

if we need to find the value of x then we need to

5x + 10 = 65 ( Vertically opposite angles are same )

5x = 65 -10

5x = 55

x = 55/5

x = 11

Answer:

x=11

Step-by-step explanation:

5x+10=65

5x=65-10

5x=55

5x÷5=55÷5

x=11

Step-by-step explanation:

[tex]f(x)=2x^2-44x+185\\\\=2(x^2-2*11*x)+185\\\\=2(x^2-2*11*x+11^2)+185-2*121\\\\\boxed{f(x)=2(x-11)^2-57}\\\\vertex\ is\ (11,-57)[/tex]

Answer:

f(x) = 2(x - 11)² - 57

Step-by-step explanation:

Given

f(x) = 2x² - 44x + 185 ( factor out 2 from the first two terms )

f(x) = 2(x² - 22x) + 185

To complete the square

add/ subtract ( half the coefficient of the x- term )² to x² - 22x

f(x) = 2(x² + 2(- 11)x + 121 - 121 ) + 185

     = 2(x - 11)² + 2(- 121) + 185

    = 2(x - 11)² - 242 + 185

f(x) = 2(x - 11)² - 57 ← in vertex form

The total change in temperature is a decrease of 5 degrees Celsius (ºC).

To find the total change in temperature, you simply add the individual temperature drops together.

1. First Temperature Drop: -2º (negative because it's a drop)

2. Second Temperature Drop: -3º (again, negative because it's a drop)

Now add these two drops together:

Total Change in Temperature = (-2º) + (-3º) = -5º

So, the total change in temperature is a decrease of 5 degrees Celsius (ºC).

Answer:

(5, 2 ) and (- 1, 8 )

Step-by-step explanation:

Given the equations

y = - x + 7 → (1)

y = 0.5(x - 3)²

   = 0.5(x² - 6x + 9)

y    = 0.5x² - 3x + 4.5 → (2)

Substitute y = - x + 7 into (2)

- x + 7 = 0.5x² - 3x + 4.5 ( subtract - x + 7 from both sides )

0 = 0.5x² - 2x - 2.5 ( multiply through by 2 ) , then

x² - 4x - 5 = 0 ← in standard form

(x - 5)(x + 1) = 0 ← in factored form

Equate each factor to zero and solve for x

x - 5 = 0 ⇒ x = 5

x + 1 = 0 ⇒ x = - 1

Substitute these values into (1) for corresponding values of y

x = 5 : y = - 5 + 7 = 2 ⇒ (5, 2 )

x = - 1 : y = -(- 1) + 7 = 1 + 7 = 8 ⇒ (- 1, 8 )

Step-by-step explanation:

2 tan(60) = 2 * (sqrt(3)/2 = sqrt(3)

1 + tan^2(60) = 1/cos^2(60) = 1//1/4 = 4

The answer is going to look a little convoluted but it should be correct.

The answer so far is sqrt(3) /4

sin(60) = sqrt(3)/2    

of the 4, two is needed to get sqrt(3)/2

So far then we have sin(60)/2

If we multiply by 2 as in (sin(60)/2) we get just sin(60)

2* sqrt(3) /4 then  = 2 sin(60)
