Y = mx + c.
m = the gradient : i.e. The slope
c = the y intercept, (where the line passes through the y axis)
The slope (gradient/) = 2
So now you have y = 2x + c
You have also been told that the y intercept is 1
So now you have the equation : y = 2x + 1
The line on a graph goes up, as the gradient is positive.
It is also a straight line as the x has a indices of 1.

Y = mx + b

in this case m = 2 and b = 1 so
equation

Answer:

5 3/4

Step-by-step explanation:

I say this because...

9-3= 6 and 4/4 -1/4 equals 3/4 so you take the whole that was 6 and put 5 since you took 1/4 out of the whole number

Vera_Pavlovna [14]

Answer:

<em>About 900 cans not stamped in 3 hours</em>

Step-by-step explanation:

<u>Proportions</u>

Sally found that 150 cans were not stamped in the 1/2 hour trial run.

Following the same proportion in time, we can say:

150 cans not stamped in 1/2 hour. Multiplying by 2:

300 cans not stamped in 1 hour. Multiplying by 3:

900 cans not stamped in 3 hours

About 900 cans not stamped in 3 hours

Solve the system of equations. y= x + 17, y= 3x+1
Lemur [1.5K]

Answer:

x=8, y=25. As a point it's (8,25)

Step-by-step explanation:

here is the system:

y=x+17

y=3x+1

notice how both of the equations equal y. Therefore, we can substitute one expression as y in the other expression. (It'll equal y=y, which is a true statement)

so it'll be:

3x+1=x+17

subtract 1 from both sides

3x=x+16

subtract x from both sides

2x=16

divide by 2

x=8

now, substitute 8 as x into one of the equations and solve for y

let's take the first one for example

y=8+17

y=25

so the answer is x=8, y=25. As a point it's (8,25)

Hope this helps!

A candy bar box is in the shape of a triangular prism. The volume of the box is 3,240 cubic centimeters.
SashulF [63]
<span>B: To make the box, we need 2 triangular ends,

and 3 rectangular sides. Side the volume = 3240

and the height = 30, the area of each base (end) = 108.

The sides have areas of 30 x 42 = 720, and 30 x 15 = 450,

and there are 2 of those. So total area = 108 + 108 + 720 + 900 = 1836 cm^2
