What are the x- and y-intercepts of −6x+4y=96 ?

ankoles [38]

* intercepts "x" --> y=0

-6x + 4(0) = 96
-6x = 96
x = $- \frac{96}{6}$

x = 16

(16,0)

*intercepts "y" --> x=0

-6(0) + 4y = 96
4y = 96
y = $\frac{96}{4}$

y = 24

The sum of the digits of a three-digit number is 16 .the tens digit is two more than the units digit and the unit digit is tripl

Anit [1.1K]

Answer:

286

Step-by-step explanation:

If the three-digit number is xyz, then:

x + y + z = 16

y = z + 2

z = 3x

Substitute the third equation into the second:

y = 3x + 2

Substitute this and the third equation into the first:

x + (3x + 2) + (3x) = 16

7x + 2 = 16

7x = 14

x = 2

y = 3x + 2 = 8

z = 3x = 6

The number is 286.

Determine the sum of the arithmetic series: 5+18 +31 +44 + ... 161.

Finger [1]

Answer:

1079

Step-by-step explanation:

Hello,

18-5 = 13

31-18=13

44-31=13

161=5+13*12

So we need to compute

$\displaystyle \sum_{k=0}^{k=12} \ {(5+13k)}\\\\=\sum_{k=0}^{k=12} \ {(5)} + 13\sum_{k=1}^{k=12} \ {(k)}\\\\=13*5+13*\dfrac{12*13}{2}\\\\=65+13*13*6\\\\=65+1014\\\\=1079$

Thanks
