A proportional change means that for every change in 1 value, it is accompanied by a change in another value that is the same every time. For example, with this, if x=1 then y=2*1=2. If we move x up 1 value to 2, y=2*2=4. Next, if we move x one more value up then 3*2=y=6. As you may notice, y adds up by 2 every time. In addition, you multiply the x value by the same number every time and only that number (no adding anything) and it is therefore a proportional equation
Answer:
3x-x+2=4
Step-by-step explanation:
Number of boys = x
Number of girls = x plus 15% of x = 1.15x
Ratio of boys to girls x:1.15x = 1:1.15 = 20:23
Answer:
1, 4 complementary
2, 3 supplementary
5, 6 neither
Step-by-step explanation:
complementary angles are angles in which the sum of both is equal to 90 degrees. supplementary angles are angles in which their sum is equal to 180 degrees.

<span>The form of a linear equation that shows the slope and one point is the POINT-SLOPE FORM.
</span>Equations in point-slope form<span> look like this: y - k = m(x - h) where m is the </span>slope<span> of the line and (h, k) is a </span>point<span> on the line (any </span>point<span> works). To write an equation in </span>point-slope form<span>, given a graph of that equation, first determine the </span>slope<span>by picking two </span>points<span>.

Answer:
The second choice
Step-by-step explanation:
So first we would plug in the first term which is 2 so we would get times so next we would see that the common ration is -3 since every time the number is being multiplied by -3. so then our equation would be times . Now we would just find the choice that matches and it would be the second choice.
