7. y=-3/2x+8 (3rd answer choice)

substitute
-4=-3/2(8)+b
-4=-24/2 +b
-4=-12+b
+12 both sides
8=b

so equation would be...

y=-3/2x+8 (3rd answer choice)




8. y=-5x-17 (2nd answer choice)

substitute
-2=-5(-3)+b
-2=15+b
-15 both sides
-17=b

so the equation would be...

y=-5x-17 (2nd answer choice)


check your work by substituting each (x,y) value into the final equations if you want. hope this helps :))

In a litter of 7 kittens, each kitten weighs less than 3.5 ounces. Find all the possible values of the combined weights of the k
Dima020 [189]

Let's use w to symbolize the weight of kittens. Given by the statement "each kitten weighs less than 3.5 ounces" we know that

1*w < 3.5

We can multiply both sides of the inequality by 7 to determine the total weights

7*(1*w) < 7*(3.5)

7*w < 24.5

Since there are 7 kittens, the combined weight of the kittens is 7w, therefore the above expression could be read as "The combined weight of the kittens is less than 24.5 ounces"
