You lost minus when you were adding two equations.
-176= - 22x -12y
<span>144 =      6x   +12y
</span>-32= - 16x
x=2

88=11x+6y,
88=11*2+6y
6y=66
y=11

Check:
88=11x+6y=11*2+6*11=88 True
144=6x+12y=6*2+12*11=12+132=144 True

The cost of daylilies is $2.
The cost of pot of ivy is $11.

Answer:

13 cm

Step-by-step explanation:

The diagonal of a rectangle forms a right triangle; where the diagonal is a hypotenuse, and two sides of the rectangle are legs.

Using pythagorean's theorem (a^2 + b^2 = c^2), we can say:

5^2 + 12^2 = c^2\\25 + 144 = c^2\\169 = c^2\\13 = c

The hypotenuse is equal to 13cm.

Write the equation -3x + 4y = 16 in slope-intercept form.
Vlad1618 [11]

Answer:

y = \frac{3}{4} x + 4

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c

Given

- 3x + 4y = 16 ( add 3x to both sides )

4y = 3x + 16 ( divide all terms by 4 )

y = \frac{3}{4} x + 4 ← in slope- intercept form
