Y = log5x + 4
y = 0.698700043 + 4
y = 4.698700043
y = log4(x - 4)
y = log4(x) - log4(4)
y = log4x - log16
y = log0.6020599913x - 1.204119983
Answer:
145 cups of lemonade; 2x+1.50y=425, where y=90
Step-by-step explanation:
Let us first set up an equation, where <em>x</em> represents number of cups of lemonande, and <em>y</em> represents number of candy bars. We know that every cup of lemonade costs $2, every candy bar sold costs $1.50, and that Marcia sold a total of $425. We now have equation:
However, we actually know how many candy bars Marcia sold. Therefore, our y value is 90. Let's rewrite the equation:
<u>Therefore, Marcia sold 145 cups of lemonade.</u>

Answer:
The answer to your question is c = 20
Step-by-step explanation:
Data
a = 15
j = 24
k = 32
c = ?
Process
Use proportions to solve this problem. Compare the small triangle and the large triangle.
1.- Proportion of the small triangle
c/15
2.- Proportion of the large triangle
k/j
3.- Equal but terms and solve for c
c/15 = k/j
-Substitution
c / 15 = 32/24
c = 32(15)/24
-Result
c = 20
Answer:
Slope: -45
Y-intercept: -2
Step-by-step explanation:
The expression is written in slope-intercept form or y=mx+b.
mx is the slope and b is the slope intercept
