Answer:

yeah the slope is 1/2

Step-by-step explanation:

The slope formula is y2-y1 / x2-x1. Two points on the line such as (-3,2) and (1,4) fall on the line. y2 would be 4 the y1 would be 2. x2 would be 1 and x1 would be -3. So the formula gets set up like 4-2/1--3, which would be equal to 1/2, simply. :)

I am assuming you meant that the old machine made 248 toys in one hour instead of both if that is the case then the answer would be 744.

Steph-by-step explanation:

The new machine makes three times as many as the old machine so 248 times 3 = 744 toys in one hour

A train to New York city leaves a station every 7 minutes. Another train to Boston leaves the station every 6 minutes. Suppose i

Virty [35]

Answer:

7:12 a.m

Step-by-step explanation:

Given that:

Train to New York city leaves station every 7 minutes

Train to Boston leaves station every 6 minutes

Current time = 6:30 a.m

Time both will leave station together is obtained by finding the least common multiple of 6 and 7

Multiples of ;

6 = 6, 12, 18, 24, 30, 36, 42, 48, 54, 60,...

7 = 7, 14, 21, 28, 35, 42, 49, 56, 63, 70,...

The least common multiple of 6 and 7 is 42.

Hence, both trains will leave the station together after 42 minutes ;

Current time + 42 minutes

6:30 a.m+ 42 minutes = 7:12 a.m

F(-4) for f (x) = -4x+9<br>f(-4)=?

Dovator [93]

F(x)= -4x+9

Multiply f*x

xF=9+4x

Solve for X: -4x+xF=9+4x-4x=0

Combine like terms: -4x+4x=0

-4x+xF=9+0= 9

-9+-4x +xF = 0.
