Answer:
help me
Step-by-step explanation:
Answer:
(-1 3/5, 2 3/5)
Step-by-step explanation:
<u>Red Line</u>:
m = 3-(-1)/-2-2 = 4/-4 = -1
b = 1
<em>equation: y = -x + 1</em>
<u>Blue Line</u>:
m = 5-1/2-(-4) = 4/6 = 2/3
find 'b':
5 = 2(2/3) + b
15/3 = 4/3 + b
b = 11/3
<em>equation: y = 2/3x + 11/3</em>
<u>Find Point of Intersection</u>:
-x + 1 = 2/3x + 11/3
multiply each side by 3 to get:
-3x + 3 = 2x + 11
-5x = 8
x = -8/5
find 'y':
y = -(-8/5) + 1
y = 8/5 + 1 = 13/5
y = 2 3/5
Answer:
Cheryl is correct.
Step-by-step explanation:
Cheryl solved a problem : 84 ÷ 0.01 = 8,400.
This is absolutely right.
When we divide any whole number with the divisor having decimal, we change the divisor to a whole number before performing the division.
To do this, we multiply both the numbers (divisor and dividend) by the same power of 10, until the divisor is a whole number.
= 
to make divisor a whole number we will again multiply both the numbers by 10.
=
= 8,400
Now answer would be 8400.
Therefore, Cheryl is correct.
