Question 1: The answer would be B) 12:30. If the ratio of girls to boys in the class is 12:18, add both of the numbers to get the total number students in the class. So the ratio would be 12:30

Question 2: The answers would be B) 18/27 and C) 30:45. These two ratios if you were to simplify them, would both equal 6:9.

Question 3: The answer would be C) 9.95. To find the unit price for one cd, you would need to divide $29.85 by 3, which equals $9.95.

Question 4: The answer would be B) 240 words. To find the answer, you need to multiply 34 by 7 to find the amount of words, which is 238 words, but the closest answer to this is B.

Hope this helps!

ILL GIVE BRAINLIEST IF ITS RIGHT
Vesna [10]

Answer: 6

Step-by-step explanation:

Slope is found by doing:

\frac{y_1 - y}{x_1 - x}

(x1 and y1 must be from the same ordered pair and x and y must be from the same ordered pair, however point (x1,y1) and (x,y) can be used interchangeably)

Let us say that (x1,y1) is (3,18)

And (x,y) is (5,30)

\frac{18 - 30}{3 - 5} = \frac{-12}{-2} = 6

The polynomial of degree 4, P ( x ) , has a root of multiplicity 2 at x = 1 and roots of multiplicity 1 at x = 0 and x = − 2 . I
ICE Princess25 [194]

We want to find a polynomial given that we know its roots and a point on the graph.

We will find the polynomial:

p(x) = (183/280)*(x - 1)*(x - 1)*(x + 2)*x

We know that for a polynomial with roots {x₁, x₂, ..., xₙ} and a leading coefficient a, we can write the polynomial equation as:

p(x) = a*(x - x₁)*(x - x₂)...*(x - xₙ)

Here we know that the roots are:

  • x = 1 (two times)
  • x = 0
  • x = -2

Then the roots are: {1, 1, 0, -2}

We can write the polynomial as:

p(x) = a*(x - 1)*(x - 1)(x - 0)*(x - (-2))

p(x) = a*(x - 1)*(x - 1)*(x + 2)*x

We also know that this polynomial goes through the point (5, 336).

This means that:

p(5) = 336

Then we can solve:

336 = a*(5 - 1)*(5 - 1)*(5 + 2)*5

336 = a*(4)*(4)*(7)*5

336 = a*560

366/560 = a = 183/280

Then the polynomial is:

p(x) = (183/280)*(x - 1)*(x - 1)*(x + 2)*x
