Answer:

B. 8

Step-by-step explanation:

By evaluate, they mean substitute in the values and solve.

x + 3y - n

= 10 + 3(2) - n

= 10 + 6 - 8

= 8

Answer:

7

Step-by-step explanation:

So:a=3

b=(-2)

c=2

Substitute the numbers into each letters

so a is represented by 3,c by 2 and b -2

therefore giving us: 2

3+(-2)=9+(-2)=7

a card is drawn at random from a standard 52 card deck has a 1/13 chance of being at 8. What is the probability of the car not b

Free_Kalibri [48]

Answer:

12/13

Step-by-step explanation:

There are 52 cards in the deck

4 are aces

That leaves 52-4 or 48 that are not aces

P(not an aces) = cards that are not aces / total

= 48/52

=12/13

-1(x+2)=2(3x-6) Please solve

Korvikt [17]

$-1(x+2)=2(3x-6)$
$-1(x+2)=2(3x-6)$ distributhing -1 through parantheses
$-1x+(-1)*2=2(3x-6)$
$-x-2=2(3x-6)$ distributhing 2 through parantheses
$-x-2=2*3x-2*6$
$-x-2=6x-2*6$
$-x-2=6x-12$ add x
$-2=6x-12+x$
$-2=7x-12$ add 12
$-2+12=7x$
$10=7x$ divide by 7
$x= \frac{10}{7}$
Answer : x= 1 3/7

10) Use the graph below: What percent of strikeouts is Samar responsible 10 pointsfor?BASEBALL STRIKEOUTSCARLOSPITCHERYUSAMARJUS

JulsSmile [24]

First let's find out the total number of strikeouts, by adding the number of strikeouts of each person:

$\text{total}=13+9+5+11+8+4=50$

Now, to find the percentage of strikeouts that Samar is responsible, let's divide his number of strikeouts (5) by the total number of strikeouts (50):

$\frac{5}{50}=\frac{1}{10}=\frac{10}{100}=10\text{\%}$

So Samar is responsible for 10% of the strikeouts.

Write a polynomial function in standard form given the zeros. -1/2, -5 + i

Rama09 [41]

Answer:

y = x³ + 10.5x² + 31x + 13

Step-by-step explanation:

Complex roots (roots that have imaginary terms) always come in conjugate pairs. So if one root is -5 + i, there's another root that's -5 − i.

So the polynomial is:

y = (x + 1/2) (x − (-5 + i)) (x − (-5 − i))

Distributing:

y = (x + 1/2) (x² − (-5 + i)x − (-5 − i)x + (-5 + i)(-5 − i))

y = (x + 1/2) (x² + 5x − ix + 5x + ix + (-5 + i)(-5 − i))

y = (x + 1/2) (x² + 10x + (-5 + i)(-5 − i))

y = (x + 1/2) (x² + 10x + 25 + 5i − 5i − i²)

y = (x + 1/2) (x² + 10x + 25 + 1)

y = (x + 1/2) (x² + 10x + 26)

y = x(x² + 10x + 26) + 1/2(x² + 10x + 26)

y = x³ + 10x² + 26x + 1/2x² + 5x + 13

y = x³ + 10.5x² + 31x + 13
