\bf \textit{area of a triangle}\\\\ A=\cfrac{1}{2}bh~~ \begin{cases} b=base\\ h=height\\[-0.5em] \hrulefill\\ A=\frac{2}{5}\\ h=\frac{6}{5} \end{cases}\implies \cfrac{2}{5}=\cfrac{1}{2}b\left( \cfrac{6}{5} \right)\implies \cfrac{2}{5}=\cfrac{6b}{10}\implies \cfrac{2}{5}=\cfrac{3b}{5} \\\\\\ 10=15b\implies \stackrel{\textit{dividing both sides by 15}}{\cfrac{10}{15}=\cfrac{15b}{15}}\implies \cfrac{10}{15}=b\implies \cfrac{2}{3}=b

A person can pay $8 for a membership to the science museum and then go to the museum for just $1 per visit. What is the maximum
laila [671]

The maximum number of visits for a member of science museum is 36.

Step-by-step explanation:

Given,

Membership fee = $8

Per visit fee = $1

Total cost = $44

Let,

x be the number of visits

y be the total cost

Total cost = per visit fee*number of visits + membership fee

y = x+8

44=x+8\\44-8=x\\36=x\\x=36

The maximum number of visits for a member of science museum is 36.

What is the equation of the line in slope-intercept form with slope -3/2 and y-intercept -5?
V125BC [204]

About Slope Intercept Form:

  • y = mx + b
  • m represents the slope
  • b represents the y-intercept or AKA the starting point

ABOUT PROBLEM:

  • Since -3/2 is the slope, it represents m in Slope Intercept Form
  • Since -5 is the y-intercept, it represents b in Slope Intrecept Form

y = mx + b

y = -3/2x + -5 --- IN Slope Intercept Form


Hope this helps you!!! :)
