Answer:
16 Unit
Step-by-step explanation:
With P(-2,1) , Q(6,1) , R(4,-3) , S(4,1) , the triangle and its altitude look like the one attached in figure.
The length of base PQ is the difference in the x-coordinates of P and Q,
6-(-2)=6+2=8 , because the y-coordinates are both the same as 1.
The height (the length of altitude RS is the difference in the y-coordinates of R and S,
1-(-3)=1+3=4 , because the y-coordinates are both the same as 4 .
The area is
.
Answer:
Writing the inequality, we have;
the solution to the inequality is;
Explanation:
Given that Natalie has $680 to spend at a bicycle store for some new gear and biking outfits.
Total spending must not exceed $680
She buys a new bicycle for $383.33.
• She buys 2 bicycle reflectors for $7.61 each and a pair of bike gloves for $22.01.
She plans to spend some or all of the money she has left to buy new biking outfits
for $32.43 each.
let x represent the number of biking outfits she can buy.
Total spending is;
Writing the inequality, we have;
we can now solve the inequality;
Therefore, the solution to the inequality is;
