3x + 11.63 = 20
3x + 11.63 - 11.63 = 20 - 11.63
3x = 8.37

by subtracting the 11.63 from both sides, this tells us how much the grapes cost....not per lb., but for the total of all the grapes.

Identify all factors of the expression 〖4x〗^2+17x-15.
Basile [38]

The factors of given expression are: -5 and 3/4

Step-by-step explanation:

Given equation is:

4x^2+17x-15

Making pairs for the mid-term 17x by factoring the product of co-efficient of 4x^2 and 15

4x^2+20x-3x-15

= 4x(x+5) - 3(x+5)

=(4x-3)(x+5)

Now

4x-3 = 0\\4x = 3\\x = \frac{3}{4}

x+5 = 0\\x = -5

Hence,

The factors of given expression are: -5 and 3/4

Answer:

y = 2 ( x − 1 ) ^ 2 + 2

Step-by-step explanation:

y = a ( x − h ) ^ 2 + k

where vertex is (h,k) = (1,2)

h=1, k=2

y = a ( x − 1 ) ^ 2 + 2

sub ( 3,10)

10 = a (3 - 1)^2 + 2

a=2

y = 2 ( x − 1 ) ^ 2 + 2

What are the solutions to –2|x| = –6?<br><br> Show your work please
dmitriy555 [2]

Answer:

[See Below]

Step-by-step explanation:

✦ Divide by -2 on each side:

  ✧ -2 / -2 = Cancels Out

  ✧ -6 / -2 = 3

So x would be 3, -3.

- |x| Just means absolute value. Which in short just means if it's negative it becomes positive.
