475 = 400 + 70 + 5
therefore
9 × 475 = 9 × (400 +70 + 5) = 9 × 400 + 9 × 70 + 9 × 5
=3600 + 630 + 45 = 4275
I think... It's better to use Distributive Property:
(a - b) × c = a × c - b × c
9 = 10 - 1
therefore:
<span>(10 - 1) ×475 = 10 × 475 - 1 × 475 = 4750 - 475 = 4275</span>
1st ... 5
2... it doesn't intersect the y axis
3.. 3
First find the slope by calculating rise (change in x) over run (change in y).
(4/5)-0/0-(-5)
(4/5)/5=0.16
The y intercept is 4/5. We know this because y interceot is the value of y when x is 0.
Then plug this into y=mx+b where m is slope andb is y intercept.
Final answer: y=0.16x+0.8 or y= 4/25x+ 4/5
Answer:
x < 12
Step-by-step explanation:
So 8 times the sum of a number and 26 is less than 304. To find the number, lets write a equation where the "number" is x.
8 times the sum of a number and 26 can be written as 8 * x+26, however since the sum of x and 26 are being multiplied, we write this as 8(x+26). Since 8 times the sum of a number and 26 is less than 304, we set 8(x+26) to < 304. This gives us our equation:
8(x+26) < 304
Lets start to solve for x by dividing by 8, giving us:
x+26 < 38
Now lets isolate x by subtracting 26 from both sides, which gives us our answer:
x < 12
So x is less than 12.
Hope this helps!
