Does a altitude of a triangle divides the triangle into two equal halves??​
trapecia [35]

This only happens if the triangle is isosceles.

Suppose you have triangle ABC, with AB=AC. In this case, the altitude AH bisects both the base BC and the angle BAC, so triangle ABH and ACH are congruent becase they have AH in common, BH=CH and AB=BC because the triangle is isosceles.

You work two jobs. You earn $14.64 per hour as a salesperson and $12.20 per hour stocking shelves. Your combined earnings this m
Igoryamba

I'm assuming you have to graph a line that shows the combination of earnings.

Our equation is 14.64y + 12.20x = 219.60

We'll be solving for x and y. We'll need to substitute the variables, one at a time, to 0, in order to find their intercepts.

Let's do x first.

14.64(0) + 12.20x = 219.60

12.20x = 219.60

Divide by 12.20 on both sides.

x = 18

Now let's solve for y.

14.46y + 12.20(0) = 219.60

14.46y = 219.60

Divide both sides by 14.46.

y = 15.18

That is actually a long decmal, but since we're dealing with money, we round it down to the nearest cent.

So, now we know x = 18 and y = 15.18.

Graph those on the x coordinate plane and the y coordinate plane, and make a line connecting the two. That line represents all the solutions.

David is looking for the best deal on a laptop that regularly costs $719. Help him compare the price of the laptop at a
NemiM [27]

Answer:

A) $287.60.

B) $323.55.

C) David would pay more for the laptop at the store.

Step-by-step explanation:

A) Given that the store's website is offering the laptop at a 60% discount off the regular price of $ 719, ignoring tax and shipping, the sale price is obtained through the following calculation:

100 - 60 = 40

719 x 0.40 = X

287.6 = X

Therefore, in this case the sale price would be $ 287.6.

B) Since the store is having a sale, offering a 50% discount off the regular price of the laptop, and David also has an in-store-only coupon for an additional 10% off the sale price, ignoring tax, the price of sale is obtained through the following calculation:

(719 x 0.5) x 0.9 = X

359.5 x 0.9 = X

323.55 = X

Thus, the sale price in the present case would be $ 323.55.

how do graphs of y=1/x and y=5/(x+6) compare? I know the second graph shifts to left by 6 units but does it move down and how ma
yawa3891 [41]
<span>By multiplying the first function with number 5, the graph will stretch by the order of five, meaning that in the second graph every value of the x will correspond to the 5 times bigger value of y than in the first case. Due to the +6 component, the second graph shifts to the left by 6 units.</span>
