X=goats y=ducks 4x+2y=34 x+y=11 -y -y x=11-y 4(11-y)+2y=34 44-4y+2y=34 44-2y=34 -44 -44 -2y=10 /2 /2 y=5 x+y=11 x+5=11 -5 -5 x=6 goats=6 ducks=5

Use the distributive property and the diagram to match an expression that is equivalent to 12+4x.

Ket [755]

4(3+x)

This is because 4*3=12 and 4*x is 4x so you get 12+4x which is the original equation

X^2-x+12 solve using the quadratic formula

devlian [24]

The quadratic formula is $x=\frac{-b\pm\sqrt{b^2-4ac} }{2a}$ .

From the problem, a is 1, b is -1, and c is 12. Plugging in these values gives:

$x=\frac{-(-1(-1)\pm\sqrt{(-1)^2-4(1)(12)} }{2(1)}$

Because there is a square root of a negative number, there is no solution.

Rewrite the following equation in slope-intercept form.<br><br> –3y + 5 = –4x

snow_lady [41]

Answer:

4x+3y=5

Step-by-step explanation:

Subtract

4

x

from both sides of the equation.

3y = 5− 4x

Divide each term by 3 and simplify.

y= −4x 3+53

Rewrite in slope-intercept form.
