HELP <br> what are the coefficients of 7x^4-9x^3+2x^2

Nikitich [7]

In this case, whenever you see a number directly in front of x, multiplying itself by/with x, it's a coefficient.

That applies to the numbers 7, 9, and 2 if I'm reading this correctly. Hope this helps!

X=4/5 Y=4/X+SQRT X +0.2 -5X What is the value of Y

fenix001 [56]

You seem to be saying that Y=4/X+SQRT X +0.2 -5X, and that x is given as 4/5. To evaluate <span>Y=4/X+SQRT X +0.2 -5X, replace each occurrence of x with 4/5:

y = 4 / (4/5) + sqrt(4/5) + 0.2 - 5(4/5)
= 5 + 2 / sqrt(5) + 0.2 - 4
Can you simplify this further?

Julia is making pasta necklaces and wreaths. She uses n noodles in a necklace and 3/5 that number of noodles in wreaths. Which e

Fofino [41]

Answer:

the expression that shows the number of noodles Julia uses to make 9 necklaces and 20 wreaths

= (9 $\times$ n ) + (20 $\times$ (3/5)n) = 9n + 12n = 21n

Step-by-step explanation:

i) there are n noodles in a necklace

ii) there are 9 necklaces

iii) therefore the number of noodles used to make the nine necklaces = 9 $\times$ n = 9n

iv) there are 3/5 noodles in a wreath

v) there are 20 wreaths

vi) therefore the number of noodles used to make the nine necklaces

= 20 $\times$ (3/5)n = 12n

vii) the expression that shows the number of noodles Julia uses to make 9 necklaces and 20 wreaths

= (9 $\times$ n ) + (20 $\times$ (3/5)n) = 9n + 12n = 21n
