Determine if x + 2 is a factor of p(x) = x 4 + 3x 3 + 4x 2 - 8 and explain why.

Andrej [43]

The Factor Theorem says (x - a) is a factor of function p(x) if p(a)=0

so check for p(-2)

= -2^4 +3(-2)^3 + 4(-2)^2 - 8

= 16 - 24 +16 -8

= 0

so (x + 2) is a factor

Suzanne bought 50 apples at the apple orchard. She bought 4 times as many red apples as green apples. How many more red apples t

Natali [406]

Let x = the number of green apples, let 4x = the number of red apples
4x + x = 50 Set up the quation
5x = 50 Combine like terms
---- ---- Divide by 5 on both sides to get x alone
5 5
x = 10 green apples
4x = 4(10) = 40 red apples

40 - 10 = 30. Suzanne bought 30 more red apples than green apples.

PLSS HELPP WILL GIVE BRAINLIEST PLS ANSWER ALL 3

podryga [215]

Answer:

$\large \boxed{\sf non \ linear, \ non \ linear, \ linear, \ linear}$

Step-by-step explanation:

Write the equations in the form y = mx + b

If the equation contains exponents then it is non-linear, if not then it is linear.

2xy = 3

This graph forms a curve so it is non-linear

y = 1x³ + 5

This equation is non-linear because it contains an exponent

y = x/3

y = 1/3x + 0

This equation is linear ( no exponent(s) )

2y = 1/2x

y = 1/4x + 0

This equation is linear ( no exponent(s) )
