Y=-x+4
y=-2x-4
 (

for elimination subtract as is
y=-x+4
y=-2x-4
-------------
0 = 1 x + 8
so
x = -8
then get y = 8+4 = 12)

The length of the top of a table is 3 m greater than the width. The area is 70 m^2. Find the dimensions of the table.
Keith_Richards [23]

Let's call the width x. Since the length is three more than the width, it is x+3.


The area (which we know to be 70) is given by the multiplication of width and length:


x(x+3) = 70 \iff x^2+3x = 70 \iff x^2+3x-70 = 0


To solve this equation, you can use the usual quadratic formula: given an equation ax^2+bx+c=0, the two solutions are


x_{1,2} = \frac{-b\pm\sqrt{b^2-4ac}}{2a}


which in your case becomes


x_{1,2} = \frac{-3\pm\sqrt{9+280}}{2}  = \frac{-3\pm 17}{2}


So, two solutions are


\frac{-3-17}{20} = -10,\qquad \frac{-3+17}{2} = 7


Since we can't accept a negative length, we only accept the second solution.


So, the dimensions are 7 and 10

What is the m<2 = ?
Degger [83]

Answer:

m∠2=9

Step-by-step explanation:

Hello There!

The problem states that the angles are complementary angles

Complementary angles are angles that have measures that add up to equal 90

So given one of the angles we can find the missing angle by subtracting the known angle from 90

90 - 81 = 9

so we can conclude that the measure of angle 2 is 9
