The table shows ordered pairs of the function . What is the value of y when ?
LiRa [457]

Answer:

(B) -8

Step-by-step explanation:

Given the 2-column table below:

\left|\begin{array}{c|c}x&y\\--&--\\-3&14\\-1&10\\1&6\\4&0\\8&?\\10&-12\end{array}\right|

Taking the pair (-3,14) and (-1,10)

Slope, m=\dfrac{10-14}{-1-(-3)} =\dfrac{-4}{2} =-2

Taking the pair (1,6) and (4,0)

Slope, m=\dfrac{0-6}{4-1} =\dfrac{-6}{3} =-2

Since the slope is constant, the table represents a linear function whose slope is -2. Therefore:

Taking the pair (8,y) and (4,0)

Slope, m=\dfrac{0-y}{4-8} =-2

\dfrac{-y}{-4} =-2\\y=-2*4=-8

Therefore, the value of ? on the y-column is -8.

Two sides of a triangle are equal in length. The length of the third side is three meters less than the sum of the lengths of th
strojnjashka [21]
We have an isosceles triangle: 
The length of the sides are:
side₁=side₂=x
side₃=(x+x)-3=2x-3
Perimeter of a triangle=is the sum of the all sides.

we have this equation:
x+x+(2x-3)=29
4x=29+3
4x=32
x=32/4
x=8

The length of the third triangle will be: 2x-3=2*8-3=16-3=13

Answer: The length of the longest side of the triangle would be 13 meters.

olya-2409 [2.1K]

Answer:

The correct answer is C

Step-by-step explanation:

The height of the original triangle is 3 and the length is 6, so we have a ratio of 3:6. The only triangle that works is the one with a height of 5 and a length of 10 because both simplify to 1:2.

Hope this helped!
