KatRina [158]3 years ago

Answer:

Zeros: -3 odd mult.; 0 odd mult.; 2 odd mult.

Positive leading coefficient

Odd degree likely 3

Step-by-step explanation:

A polynomial graph has several features we look for to determine the equations.

  • The zeros of the function are the x-intercepts. If the x-intercepts touch but do not cross then the intercepts have an even multiplicity like 2, 4, 6, etc. If the x-intercepts cross over then they have an odd multiplicity.
  • Degree is the exponent or multiplicity of each zero. Therefore if we know the multiplicity of each zero we can add them together to find or make an educated guess for the degree of the entire polynomial.
  • The shape of the graph tells us what type of polynomial. Odd degrees have a backwards S shape. Even degrees have a W shape. The shape can even tell us the if the equation has a positive or negative leading coefficient. Upside down W or an M shape is negative. While a sideways S shape is negative.

The ratio of Shauntay's cards to Jessica's cards is 5 to 3. After Shauntay gives Jessica 12 of her cards, both girls have the sa
Zepler [3.9K]

Answer:

They have 48 cards.

Step-by-step explanation:

let s be the number of Shauntay's cards and j be the number of Jessica's cards.

The ratio of Shauntay's cards to Jessica's cards is 5 to 3, then

(1) \frac{s}{j} =\frac{5}{3}

After Shauntay gives Jessica 12 of her cards, both girls have the same number of cards, then

(2) s-12 =j+12.

From (2), we get s= j+24. If we put j+24 instead of s in (1) we get:

\frac{j+24}{j} =\frac{5}{3}

3×j+24×3 = 5×j  From this we get;

2×j=72  and j=36

After Shauntay gives Jessica 12 of her cards, Shauntay and Jessica would have 48 cards.

which equations represent in point slope form, the line that passes through the points (-3,2) and (0,0) ?
alexandr1967 [171]

Answer:  First Option is correct.

Explanation:

Since we have given that

there are two points from which the line is passing through :

(-3,2)\ and\ (0,0)

We have to use the two point slope form .

As we know the " Two point slope form" i.e.

y-y_0=\frac{y_2-y_1}{x_2-x_1}(x-x_1)

Here,

x_1=-3\\\\x_2=0\\\\y_1=2\\\\y_2=0

So, our equation becomes,

(y-2)=\frac{0-2}{0+3}(x+3)\\\\(y-2)=\frac{-2}{3}(x+3)

Hence, First Option is correct.

Ill give brainliest to best answer.
Lera25 [3.4K]

Answer:

-3.25 >-2.5 +r

Option 4 is right.

Step-by-step explanation:

Given picture is a graph of number line representing the area to the left of -0.75 not including -0.75

i.e. the graph shows r<-0.75, where r is a variable

Subtract 2.5 to both the sides

we get

-2.5+r <-0.75-2.5

or -2.5+r <-3.25

Or -3.25 >-2.5 +r

Option 4 is right.

Why other options are wrong:

i) 3.25<r+2.5.  0 satisfies this inequality but not included in the graph. Hence wrong.

ii)3.25>2.5+r

r=0 satisiffes this contradicting the graph again.

Thus second option is right.

iii) -3.25<-2.5+r

Here r =0 satisfies this equation contrary to graph.  Hence option iii is wrong.
