Add (5x3+7x−8)+(2x3−5x2−x+3).

Answer:

The solution is (0, 4)

Step-by-step explanation:

Please pay attention to the first two equations and drop the last two:

12x−5y=−20 y=x+4 x=x=x, equals y=y=y   should ideally be:

12x−5y=−20

y=x+4

Let's find x.  Substitute x + 4 for y in the first equation, obtaining:

12x - 5(x + 4) = -20

Carrying out the indicated multiplication, we get:

12x - 5x - 20 = -20, or 7x = 0

If x = 0 then y must be 0 + 4, or 4.  

The solution is (0, 4)

Answer:x=0 y=4

Step-by-step explanation:

Answer:

f(x)=(x-2)(x+2)(x-4)

Answer: Memorize the formula

Step-by-step explanation:

( x / a )^2 - ( y / b )^2 = 1

Where a and b are the semi-axis

The value of a is half the distance from points that cuts off x-axis, in this case

From -5 to 5 there is 10 so 5 is value of "a"

Value of b can find by the formula

c^2 = a^2 + b^2

Which c is the value of the point bold on the rightmost place in x axis. In this case its 13

13^2 = 5^2 + b^2

169 = 25 + b^2

b = 12

SO we got a = 5, b = 12

ANSWER: (x/5)^2 - (y/12)^2 = 1

Answer:

665

Step-by-step explanation:

The range is the difference between the smallest and highest numbers in a list or set. To find the range, first put all the numbers in order. Then subtract (take away) the lowest number from the highest. The answer gives you the range of the list.

Answer:

The Range is 655

Answer:

B, C , F

Step-by-step explanation:

The age multiplied 55, so the shell grows at rate of 55mm per year

in fact if the age is 2 we have (55 x 2) = 55 + 55

if 3 = (55 x 3) = 55 + 55 + 55

and so on

When the turtle is hatched the shell is 37 mm in lenght.

In fact, if we substitute 0 to a, we have

s = (55 x 0) + 37

s = 37

when the turtle is 1 year old, the shell is 92 mm in length.

in fact if we substitu a with 1, we have

s = (55 x 1) + 37

s = 55 + 37

s = 92

Answer:

1.75(x)

Step-by-step explanation:

you can make an algebraic expression to make this simpler. if x = the number of tickets. then, you want to create the expression. it will be ....    1.75(x).

you plug whatever number you need for the table in as x. for example, if you want to see how much money diego would make for 6 tickets you write   1.75*6

Answer:

15 customers

Step-by-step explanation:

Given data

Total Number of customers= 25

60% of 25 customers made an additional purchase

Hence the number of customers that made additional purchase is

=60/100*25

=0.6*25

=15customer

Hence 15 customers made additional purchase

Answer:

x ≈ 47°

Step-by-step explanation:

Using the sine ratio in the right triangle

sinx° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{8}{11}[/tex] , then

x = [tex]sin^{-1}[/tex] ([tex]\frac{8}{11}[/tex] ) ≈ 47° ( to the nearest degree )

Answer:

I think it C

Step-by-step explanation:

Let's solve your equation step-by-step.

(k−4)2=9

Step 1: Simplify both sides of the equation.

k2−8k+16=9

Step 2: Subtract 9 from both sides.

k2−8k+16−9=9−9

k2−8k+7=0

Step 3: Factor left side of equation.

(k−1)(k−7)=0

Step 4: Set factors equal to 0.

k−1=0 or k−7=0

k=1 or k=7

Answer:

k=1 or k=7

Hope this helps! :)

Square both sides:

K -4 = sqrt(9)

With the answer being a square root rewrite with a postive and negative value:

K-4 = sqrt(9)

And

K-4 = -sqrt(9)

Simplify each:

K-4 = 3

And

K-4 = -3

Solving for k in each one you get answer
