Yes, Graphs (depending on which one but I'm assuming your talking about coordinate grids) are proportional because they have on vertical and one horizontal line dividing them. They extend infinitely
So you're trying to find what number is like that right? Well multiply the denominator by the 20 (20*4) which equals 100, so 100-20 (the one fourth) is 80. So 3/4 fourths of 100 is 20.
Step-by-step explanation:
y=-2x+1 so we say (-2x+1)
we flip the equation by saying
-2x+1 -1=y+-1
-2x=y-1
Divide both sides by -2
-2÷-1 = y-1÷-2
so x=-1÷2 y=+1÷2
Answer:
x² - 10x + 21
Explanation:
To answer this question, we will simply multiply each term from the first bracket by each term from the second and then combine like terms to get the final expression.
This can be done as follows:
(x - 3)(x - 7)
x(x) + x(-7) -3(x) -3(-7)
x² - 7x - 3x + 21
x² - 10x + 21
Hope this helps :)
