No one helped so im asking for these 2 again
ipn [44]

Answer:

3. Option No. 2:  

6x + 2y = 22

3x + 3y = 18

4. Option No. 2:

$2.50

Step by step explanation:

4. 6x + 2y = 22  

 (3x + 3y = 18) * 2

- Negate

6x + 2y = 22

6x + 6y = 36

2y - 6y = 22 - 36

-4y = -14

y = -14/-4

y = 3.5

An order of onion rings = $3.50

- Substitute to find for x

6x + 2(3.5) = 22

6x + 7 = 22

6x = 22 - 7

6x = 15

x = 15/6

x = 2.5

An order of French fries = $2.50

Find the value of b that makes <img src="https://tex.z-dn.net/?f=%20x%5E%7B2%7D%20%2Bbx%2B%5Cfrac%7B9%7D%7B4%7D%20" id="TexFormu

Perfect square trinomial is like

(x+4)^2=x^2+8x+16
they are represented as such
ax^2+bx+c
so to solve for b you do
(√c) times 2=b so

c=9/4
square root=3/2 because 3/2 times 3/2=9/4
(√(9/4)) times 2=(3/2) times 2=6/2=3
so b=3

x^2+3x+(9/4)
if factored, it gives
(x+(3/2))(x+(3/2))  or
(x-(3/2))(x-(3/2))


if this equation is equal to 0 then x=-3/2 or 3/2

the value is 3

Damon says that to write 1 63/100 as a sum of unit fractions, you need 163 addends. Kenya says that you need 64 addends. Who is
stealth61 [152]
Damon is right because the 1 is actually 100/100 so 100 + 63 is 163.
