Is y=3x+4 a function?

Mathematics
1 answer:
Oxana [17]2 years ago
5 0

Answer:

Yes, it is a function

Step-by-step explanation:

Every possible input x value is paired with a unique output y value.

Another approach is to graph the function then conduct the VLT (vertical line test) at which point you will realize that any vertical line will intersect the graph at one point only meaning it is a function.

Hope this helps.

Sonja [21]

Answer:

x=10

Step-by-step explanation:

we know that

When two lines are crossed by another line (transversal), the angles in matching corners are called Corresponding Angles.

When the line are parallel the corresponding angles are equal in measurement.

so

In this problem

(8x+50)\°=130\° -----> by corresponding angles

see the attached figure to better understand the problem

Solve for x

Subtract 50 both sides

8x=130-50

8x=80

Divide by 8 both sides

x=80/8

x=10

Mark save $258 more than Neil. In fact Mark saved $7 for every $4 Neil saved. How much money did Mark say?
olasank [31]

Let

x---------> amount of money saved by Mark

x---------> amount of money saved by Neil


we know that

x=y+258-------> equation 1

x/y=(7/4)-------> equation 2

substitute equation 1 in equation 2

(y+258) /y=7/4--------> 4*(y+258)=7*y------> 4y+1032=7y

7y-4y=1032--------> 3y=1032------> y=$344

x=344+258------>x=$602


the answer is

$602

Dvinal [7]

Answer:

t+0.07t=t(1+0.07)=t(1.07)=1.07t

Step-by-step explanation:

There are a couple of  equivalent expressions to the function t+0.07t. For example:

t+0.07t

Factor:

t+0.07t=t(1+0.07)

If you add the terms inside the parentheses:

t(1+0.07)=t(1.07)

Basically you can add the like terms from the start and get the same result.

t+0.07t=1.07t

Therefore:

t+0.07t=t(1+0.07)=t(1.07)=1.07t
