Answer:
480
Step-by-step explanation:
Let h represent the number of high-quality downloads. Then the total download size is ...
4.1h +2.7(1130-h) = 3723
1.4h = 672 . . . . . . . . . . . . . . subtract 2.7·1130 = 3051
h = 480 . . . . . . . divide by 1.4
There were 480 downloads of the high-quality version.
Hello!
So, here you want to do the distributive property.
Start on the left side of the + sign...
-3*u = -3u
-3*3 = -9
So we now we have:
(-3u + -9) + 4(4u + 2)
Now we focus on the right side of the + sign...
4*4u=16u
4*2=8
So now we have:
(-3u + -9) + (16u + 8)
Now you want to combine like terms. Start by adding terms with the same variable. So, we need to add -3u and 16u
<em>-3u + 16u =</em> 13u
Now we have:
13u + -9 + 8
Now add the constants, -9 + 8
-9 + 8 = -1
So, the simplified expression would be:
13u - 1 or 13u + -1
7. X2=25
X=5, x=—5
8. (X—3)2=49
X=10, x=—4
9. X2+3x—28.
X=4, x=—7.
10. 5x2–8=3x.
X=8/5, x=—1
Answer:
y = -2/3x + 1
Step-by-step explanation:
Put -2/3x + 1 into y= on the graphing calculator and the point (6,-3) is in the table.
