Function A is represented by the equation y = 6x - 1.

Mathematics
1 answer:
Nezavi [6.7K]3 years ago

Answer:

The function graphed is f(x) = 3x + 1

See that the y=intercept is at (0,1). That's where the +1 comes from.  

Note that the graph goes up 3 spaces every time it goes 1 to the right.  3/1 = 3 is the slope.

The answer to 12 is C.

The answer to 13 is B.  Neither is a function.  For a function of x to exist, for every x, there must be only one y.  In both tables, there's a number for x that gives two different y's.

Step-by-step explanation:

If three times the larger of two numbers is four times the smaller and the difference between the numbers is 8, then the larger
MaRussiya [10]

Answer:

Larger number = 32

Step-by-step explanation:

Smaller number = x

Larger number = y

y - x = 8    -----------(I)

3y = 4x  ---------------(II)

3y/4 = x

Plug in x = 3y/4 in equation (I)

y - \frac{3}{4}y = 8\\\\\frac{4}{4}y - \frac{3}{4}y = 8\\\\\frac{1}{4}y = 8\\

 y = 8*4

  y = 32

Plug in y = 32 in equation (II)

3y = 4x

3*32 = 4x

4x = 3*32

x = \frac{3*32}{4}

x = 3 *8

x = 24

(01.02 LC)Simplify negative 7 and 1 over 8 − negative 9 and 1 over 2. negative 2 and 3 over 8 negative 16 and 5 over 8 16 and 5
user100 [1]
Your question seems to be -7 +(1/8) -(-9) + (1/2) but then there is a decimal in front of the next -2 so that makes no sense unless that is a period before starting a new equation. You can simply type this beginning section into a calculator to get your answer of (21/8), but I have a feeling you just tried to copy and paste a test question and it did not format correctly in your question so is probably much more complicated than using a calculator. 
A better idea would be to write it in math terms instead of words, then find a common denominator so you can simplify. Writing it out in words makes it too hard for your brain to think about it in terms of math.
