A(-1;14), x=-1, y=14

B(2;-10), x=2, y=-10

General equation for linear function is y=mx+b

Let's solve system of equations

\displaystyle\\\left \{ {{14=-1m+b} \atop {-10=2m+b}} \right. \\\\\left \{ {{b=14+m} \atop {2m+b=-10}} \right. \\\\2m+(14+m)=-10\\3m=-24\\m=-8=>b=14+(-8)=6\\\text{Answer}: y=-8m+6

Find the altitude of an isosceles triangle with a vertex angle of 70° and a base of 246
Neporo4naja [7]
The base angles are both equal to (180-70) / 2 =  55 degrees

and 1/2 base = 123 

so we have tan 55 =  a / 123  where a = altitude
a = 123 * tan55 =  175.66

If 6!+7!+8!=(n)(6!), then the value of n is<br> A) 15<br> B)16<br> C)63<br> D)64<br> E)15!
gladu [14]
6!+7!+8!=(n)(6!)
calculate the individual values first:
6!=720
7!=5040
8!=40320

plug them into the equation:
720+5040+40320=n720
solve for n
5760+40320=n720
46080=n720
divide both sides by 720 to isolate n
46080/720=n720/720
64=n

Anna wanted to buy a camera. The first discount store sold her favorite camera for $95. The second store sold the same camera fo
lions [1.4K]

The second store offered the better buy at the price of $92.00.

What is better buy?

Better buy refers to the lowest price out of the prices offered by the three stores.

In order to determine the lowest price, the no discount price of the first store needs to be compared to the prices of  two other stores, bearing that after-discount price is the pre-discount price multiplied by 1 minus the discount rate.

First store price=$95.00

Second store after-discount price=pre-tax discount price*(1-discount rate)

pre-discount price=$115

discount rate=20%

Second store after-discount price=$115*(1-20%)

Second store after-discount price=$92.00

Third store after-discount price=pre-tax discount price*(1-discount rate)

pre-discount price=$105

discount rate=10%

Third store after-discount price=$105*(1-10%)

Third store after-discount price=$94.50

PLS ANSWER !!!! <br><br> what is the formula when finding the slope given in two ordered pairs
Katarina [22]

Answer: Since you already know that the ordered pair is in the format of (x, y), then you can label one of the ordered pairs as 1 and kind of distribute it to get 1(x, y) = (x-sub1, y-sub1). Then just use the slope formula (y2-y1)/(x2-x1).
