-4x + 3y = -2 y = x - 1 Solve the system of equations for x and y.

viva [34]

Answer:

(-1, -2)

Step-by-step explanation:

Plug (x-1) for y in the first equation:

-4x + 3(x-1) = -2

Simplify:

-4x + 3x - 3 = -2

-x = 1

x = -1

Plug in x=-1 into the second equation:

y = (-1) - 1

y = -2

What is the sum of -36 4/9 - (10 2/9) - (18 2/9)

grigory [225]

let's firstly convert the mixed fractions to improper fractions and then add them up.

$\bf \stackrel{mixed}{36\frac{4}{9}}\implies \cfrac{36\cdot 9+4}{9}\implies \stackrel{improper}{\cfrac{329}{9}} \\\\\\ \stackrel{mixed}{10\frac{2}{9}}\implies \cfrac{10\cdot 9+2}{9}\implies \stackrel{improper}{\cfrac{92}{9}}~\hfill \stackrel{mixed}{18\frac{2}{9}}\implies \cfrac{18\cdot 9+2}{9}\implies \stackrel{improper}{\cfrac{164}{9}} \\\\[-0.35em] ~\dotfill$

$\bf -\cfrac{329}{9}-\cfrac{92}{9}-\cfrac{164}{9}\implies \stackrel{\textit{using the LCD of 9}}{\cfrac{-329-92-164}{9}}\implies -\cfrac{585}{9}\implies -65$

If y varies directly as x and y = 208 when x = 16, what is the value of y when x = 11? a. 143 b. 121 c. 16 d. 169

Reil [10]

Answer:

Y )0 X

Y=KX

K=Y/X

when x=16 and y=208

K=208/16

K=13

when x=11 and y=?

Y=KX

Y=13 *11

Y=143

Say that the following is true:

sergiy2304 [10]

W = 1.414213562 (or 2 squared)
x = 2 (because the y gets cancelled out in the first equation)
y = 1 (since 2(1)=2(1))

tell me if i’m right :)
