m =
y - = m( x - ) point - slope form of a line.
y = mx + b slope- intercept form of a line.
~~~~~~~~~~~~~~~~~
( - 2, - 7 )
( 0, - 4 )
m = =
y - ( - 4 ) = ( x - 0 )
y + 4 = x
<em>y = </em><em> x - 4</em> slope- intercept form
<em>3x - 2y = 8</em> standard form
A and D are the solutions that make the inequality true.
6^2= 36
9^2= 81
10^2= 100
-4^2= 16
-9^2+ 81
-12^2= 144
The answer is a. Because at approximately 17 weeks the two lines meet.
Answer: b. 51 - 3
Step-by-step explanation:
Given, Easha has 3 less than 5 times the number of quarters (I) that Isabelle has.
Here I is the number of quarters that Isabelle has.
Then, as per given,
Number of quarters Easha has = 5 ( number of quarters that Isabelle has) -3
= 5I-3
Hence, the expression shows the number of quarters Easha has is "5I-3"
So the correct option is b.
Hello,
Penny==>a*10 (a is an integer)
Kenny==>b*18 (b is an integer)
a*10=b*18==>a=9*b/5 ==>b=5+n*5
a=9*(5+5*n)/5=9*(1+n)=9+9n
If n=0 then a=9 and b=5 :Number od cards: 9*10=10, 5*18=90
if n=1 then a=19 and b=10: Number of cards: 19*10=190>100 to exclude.
So number of cards=90
