3 0

Answer:

x = - 1, y = 3 or (-1 , 3)

Step-by-step explanation:

x – 3y + 10 = 0 x = 3y - 10 ... plug in

x² + y² = 10

(3y-10)² + y² = 10

10y² - 60y +90 = 0

y² - 6y + 9 = 0

(y - 3)² = 0

y = 3

x = - 1

Jesse takes two data points from the weight and feed cost data set to calculate a slope, or average rate of change. A rat weighs

brilliants [131]

Answer:

The slope is $s =$ $0.1774 / pounds

Step-by-step explanation:

From the question we are told that

The weight of the rat is $w_1 = 3.5 \ pound$

The cost of feeding the rat per week is $c_1 =$ $4.50

The weight of a Beagle is $w_2 = 30 \ pound$

The cost of feed a Beagle per week is $c_2 =$ $9.20

Now the slope can be evaluated mathematically as

$s = \frac{c_2 -c_1 }{w_2 -w_1 }$

substituting values

$s = \frac{9.20 -4.50 }{30 -3.5 }$

$s =$ $0.1774 / pounds

A 90 pound object on earth weighs 15 pounds on the moon if an object weighs 156 pounds on earth how much is a win the moon

Tanya [424]

26 pounds

Because

E is the objects gravity in earth
M objects gravity on moon

E=km
Or
90=15k

90/15=15k/15

6=k

156=6m

156/6 =6m/6

26=m

Have a great day
