Answer:
The slope is 5x and the y-intercept is -7
Step-by-step explanation:
-12.405=-12 405/1000= 12 81/200
The frame of film is actually 50 mm high, but it looks 16 m high on the screen.
Remember that 1 m = 1,000 mm.
So everything looks (16,000)/(50) = <u>320 times</u> as big on the screen
as it is on the film. That's called the scale factor.
The penguin is 35 mm high on the film. He'll look 320 times bigger on the screen.
(320) x (35 mm) = 11,200 mm = <u>11.2 meters</u> high
8c + 6-3c -2
8c -3c + 6-2 = 5c + 4
Brainliest please!
You set (x+15) equal to 40 and solve for x.
x+15=40
-15 -15
x=25
Hope this helps!
