Answer:
$1.19
Step-by-step explanation:
Let the cost of a cheeseburger be $b and that of a chicken nugget be $n.
From the given information, we can form 2 equations.
9b +4n= 22.37 -----(1)
3b +4n= 15.23 -----(2)
Notice that the 2 equations have '4n' in them. I'll be using elimination method to solve the equation by getting rid of the 4n.
(1) -(2):
9b +4n -(3b +4n)= 22.37 -15.23
9b +4n -3b -4n= 7.14
6b= 7.14 <em>(</em><em>simplify</em><em>)</em>
b= 7.14 ÷6 <em>(</em><em>÷</em><em>6</em><em> </em><em>on</em><em> </em><em>both</em><em> </em><em>sides</em><em>)</em>
b= 1.19
Thus, a cheeseburger cost $1.19.
Linear functions change at a constant rate per unit interval and take the form y=mx+b, while exponential functions change by a common ratio over equal intervals and take the form y=a^x.
Just relax, breathe deeply from the diaphragm, allow the
cleansing air to fill your brain, and take it one step at a time.
You said that <u>3t - 7 = 5t
</u>OK. Fine.
Let's just find out what <em>6t</em> is.
Subtract 3t from each side: -7 = 2t
Multiply each side by 3 : <em>-21 = 6t
</em>Did I go too fast for you ?<em>
</em>
Yes they are similar! Both share the same angle of 61° then 20x5 is 100 just like 17x5 is 85!!
Answer:
A. (-2,-4)
x = -2,
y = -4
thats the only way ik how to explain but its the correct answer
