What are the intercepts of -3x+5y=2z=60

1 answer:

5 0

Intercept at, y=0 and at x=0
-3(0)+5(y)=60
y=12 , z= 30, (y intercept) or (0,12,30)

-3(x)+5(0)=60
x=-20,z=30, (x intercept) or (-20, 0, 60)

Which side lengths form a right triangle?<br> Choose all answers that apply:

kkurt [141]

Answer:

All 3 are right triangles.

Step-by-step explanation:

In a right triangle c^2 = a^2 + b^2 where c is the longest side. ( by Pythagoras).

a) 3^2 = 9, 6^2 = 36 and √27 ^ 2 = 27

36 = 9 + 27

So this is a right triangle.

17^2 = 289, 15^2 = 225 and 8^2 = 64

289 = 225 + 64

Also right triangle.

c) √50 ^ 2 = 50, 5^2 = 25 and 5^2 = 25

So also right triangle.

for a certain year, the combined revenues for PepsiCo and coca-cila were $51 billion. If the revenue for PepsiCo was $9billiin m

BlackZzzverrR [31]

So if the combined revenues were $51 billion. Then it would be best to divide that between the two companies as a starting point. Each company would have $25.5 billion if they were split 50-50. Since PepsiCo has 9 billion more than Coca-Cola. Simply take PepsiCo's value and add $9 billion to it, which would be $34.5 billion. Finally, take $51 billion, subtract it $34.5 billion, which is PepsiCo's value to get Coca-Cola's value, which is 16.5 billion for me.

Please any help is necessary

Ugo [173]

Answer:

Option D. 50 ft

Step-by-step explanation:

we know that

The area of the figure is equal to the area of three rectangles

$A=18x+(48-36)(32-11)+(18)(32)$

$A=18x+(12)(21)+(18)(32)\\A=18x+828$

Remember that the area is given

$A= 1,728\ ft^2$

$18x+828=1,728$

solve for x

$18x=1,728-828\\18x=900\\x=50\ ft$

If DF=78, DE=5x-9, and EF=2x+10, find DE.

Kazeer [188]

Given that E is a point between Point D and F, the numerical value of segment DE is 46.

<h3>What is the numerical value of DE?</h3>

Given the data in the question;

E is a point between point D and F.
Segment DF = 78
Segment DE = 5x - 9
Segment EF = 2x + 10
Numerical value of DE = ?

Since E is a point between point D and F.

Segment DF = Segment DE + Segment EF

78 = 5x - 9 + 2x + 10

78 = 7x + 1

7x = 78 - 1

7x = 77

x = 77/7

x = 11

Hence,

Segment DE = 5x - 9

Segment DE = 5(11) - 9

Segment DE = 55 - 9

Segment DE = 46

Given that E is a point between Point D and F, the numerical value of segment DE is 46.
