Answer:
i really dont know
Step-by-step explanation:
#5: cost: y
Number of beads: x
y=0.48*x
So for 4 beads: 1.92
for 5 beads: 2.4
#6: the x th term in the sequence is y
y=17-2x
The 10th term is -3
Answer:
22.5
Step-by-step explanation:
Answer:
x = - 7 , x = 2 , x = 1
Step-by-step explanation:
note that
p(1) = 1³ + 4(1)² - 19(1) + 14 = 1 + 4 - 19 + 14 = 0
since p(1) = 0 , then x = 1 is a zero
using synthetic division
1 | 1 4 - 19 14
↓ 1 5 - 14
------------------------
1 5 - 14 0
quotient is x² + 5x - 14
equating quotient to zero
x² + 5x - 14 = 0
(x + 7)(x - 2) = 0
equate each factor to zero and solve for x
x + 7 = 0 ⇒ x = - 7
x - 2 = 0 ⇒ x = 2
then zeros are x = - 7, x = 2 , x = 1
Answer:
y=4x+40
Step-by-step explanation:
slope equals 4
x-intercept= -10
y=mx+b for the x-intercept the y equals zero so plugging zero the y and -10 to the x
0=4(-10)+b
0=-40+b now you isolate the variables
b=40 so the equation is y=4x+40 because you have the slope you just pluggin the numbers to the equation
