Answer:

5.5

Step-by-step explanation:

The <em>rate of change</em> of a relationship is the <em>ratio of corresponding changes in value</em>. Symbolically, we indicate a change with the greek letter Δ (pronounced "delta"). A <em>change in x</em> is written Δx ("delta eks") and a <em>change in y</em> is written Δy ("delta why"). We're looking for the ratio Δy/Δx ("delta y over delta eks").

Mathematically, Δx and Δy are the <em>differences</em> between two corresponding x an y values. To pick these, we can take any two rows in our table. Let's pick rows 4 and 2, nice whole numbers:

\Delta{x}=20-10=10\\\Delta{y}=112-57=55\\\Delta{y}/\Delta{x}=55/10=11/2=5.5

We can confirm that this holds for every other pair, too - picking rows 2 and 1 as an example:

\Delta{x}=10-5=5\\\Delta{y}=57-29.5=27.5\\\Delta{y}/\Delta{x}=27.5/5=275/50=11/2=5.5

Help pls yall i will give brainliest
miskamm [114]

Answer:

Y=3x+2, Y= -3x-2

Step-by-step explanation:

If you need a consistent (parallel) line you must have very similar equations, with only positives and negatives being changed. If it's Y=3x+2, only the 2 is changed from negative to positive changing the lines position. If it's Y= -3x-2 then the X value is moved to a different coordinate and the -2 keeps the change.

Hope this helps and please critique what I've done if im wrong.

Plz help me .. I am really stumped!!!!!!! part of the set for a play is a big triangular piece of plywood. the area of the trian
saul85 [17]
The way to find the area of a triangle is A=\frac{B*H}{2}
if the base is 3 feet longer then the height we can write it like this B=H+3

now we can add it to our area equation
20=\frac{H(H+3)}{2}
20=\frac{ h^{2} +3h}{2}
40=H^{2}+3H
10\frac{1}{3}=H^{2}
h=3.2ft
