34 - 6 = 28
28 x 8 = 224
After making the 6 whole sheet of paper cards for her closest friends Aimi will have 28 pieces of paper left.
Since she wants to use 1/8 of a sheet per valentine (think of it as one piece of paper can make 8 valentines) you can do 28 pieces of paper multiplied by 8 which gives you 224 valentines.
Answer:
= 15x +30y -220
Step-by-step explanation:
We can easily get another expression if we multiply each individual term, and
add together the result
30(1/2x-2)+40(3/4y-4)
= 15x-60 +30y-160
= 15x +30y -220
See attached picture below
Answer:y =ax² + bx +c
1) Point (0,7)
7 = a*0² +b*0 +c
c = 7
y=ax² + bx + 7
2) Point (1,4)
4=a*1² + b*1 + 7, ----> 4 = a +b + 7, ------> a+b= - 3
3) Point (2, 5)
5=a*2² + b*2 + 7, ----> 5=4a+2b +7,---> -2=4a+2b, ----> -1=2a + b
4) a+b= - 3, ----> b= -3 - a (substitute in the second equation)
2a+b= -1
2a - 3 - a = -1, ----> a - 3 = -1, a =2
5) a+b= - 3
2 + b = -3
b = -5
y=2x² - 5x + 7

Step-by-step explanation:
Answer:
4
Step-by-step explanation:
y = 4x + 12
In y = mx+b
The coefficient of x (m) is the slope.
So the slope is 4
