Line 1

Natalie was supposed to use PEMDAS (as we all do when doing math), which stands for: Parentheses, Exponents, Mulitplication, Division, Addition, Subtraction. However, Natalie subtracted 1 from 2 before multiplying 6 by 4 and dividing it by 2.

Hope this helps!!

In 5 minutes a conveyor belt moves 300 pounds of receyclable aluminum from the delievery truck a smaller belt moves the same qua

ladessa [460]

Answer:

It will take 3.214 minutes.

Step-by-step explanation:

It is given that, the conveyor belt transports 300 cans in 5 mins and the smaller belt transports 300 cans in 9 minutes.

Thus , the speed of conveyor belt is,

= $\frac{300}{5} = 60 cans per minute$

and of smaller belt is,

= $\frac{300}{9} = \frac{100}{3} cans per minute$

Thus, when both are used together,

conveyor belt will transport (60)(t) cans and smaller belt will transport $( \frac{100}{3})$ (t) cans per minute.

Thus the equation becomes,

$300 = (60)(t) + (\frac{100}{3})(t) = (\frac{280}{3})(t)$

t = $\frac{(300)(3)}{280} = \frac{45}{14} = 3.214 minutes$

Answer:

any coordinate outside the parabola is a reasonable answer.

Step-by-step explanation:

test the solution (0, 0) and if if that number is greater than 0 then the rest of the points outside on the inside are.

x = 0

y = 0

(0)^2 - 2(0) - 3 = -3

-3 is less than 0 so (0, 0) is not a possibility so any coordinate outside the parabola is a reasonable answer.

Which relation is a function of x? 1 {(1,2), (7, 6), (3, 2), (1, 0), (5, 6)}. 3. x=3y²–7

Answer:

The given graph shows a function of x.

Step-by-step explanation:

Neither 1 nor 3 is a single-valued relation for some values of x. The graph shown passes the vertical line test, so does represent a function.

The graph is a relation that is a function of x.

___

The attached graph is of the equation of 3. A vertical line will intersect the graph in more than one place, so the relation is NOT a function.

3250-1250=1500+2(1250-500) is this true

exis [7]

Answer:

Its false because

Step-by-step explanation:

3250-1250=1500+2.(1250-500)

2000 = 1500 + 2 . 750

2000 = 1500 + 1500

2000 != 3000

Obviously 2000 isnt the same of 3000
