r+b =12

r =2b  (twice as many red as blue)

substitute r = 2b into r+b=12

2b + b = 12

3b =12

divide by 3

b=4

r = 2b

r=2(4)

r=8

There are 4 blue pencils and 8 red pencils

Math help will mark brainliest
Nitella [24]

Answer:

a. 2

b. -1 or 2

Step-by-step explanation:

When the funtion h(x) is at 0, or h(0), the y value is visibly shown to be at 2. When the function's y-value is at -2, you need to find the x values which make that the case. You can see that at x=-1, the y value is at -2, making this our first value. You can also see the function meet -2 when x =2, making this the second value. Hope this helps!

Korvikt [17]

Answer:

736x-89

Step-by-step explanation:

i think all you can do here is add the numbers that have an X in them so adding 689x+47x=736x and you leave the 89 so it becomes 736x-89
