X intercept : (4,0)

y intercept: (0, -4)

To find the x-intercept, set y=0 to get x-0=4 => x=4 as the x-intercept.
Similarly,
To find the y-intercept, set x=0 to get 0-y=4 => y=-4 as the y-intercept.

This works for all linear equations in two unknowns.

What is the value of the function at x = 3? Enter your answer in the box.

butalik [34]

Answer:

Step-by-step explanation:

Recall a linear function, is a line on a graph made up of an infinite amount of points which satisfy the relationship. That means at x=3 there is a specific point on the line with an output. The value of a function at x=3 asks, what is the output y value for the input x value?

To find it, we locate 3 on the x-axis. We draw a vertical line directly to the line following the grid line. We mark the point on the line. We then draw a horizontal line directly to the y-axis following the grid line. The point we hit on the y-axis is the value of the function.

Here it is 4.

Find the nth term of this number sequence 7, 10, 13, 16, ... help please !!

LenKa [72]

Answer:

$a_{n}$ = 3n + 4

Step-by-step explanation:

there is a common difference between consecutive terms , that is

10 - 7 = 13 - 10 = 16 - 13 = 3

this indicates the sequence is arithmetic with nth term

$a_{n}$ = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

here a₁ = 7 and d = 3 , then

$a_{n}$ = 7 + 3(n - 1) = 7 + 3n - 3 = 3n + 4

Q: using the Substitution Method, and the value ory in

GenaCL600 [577]

Answer:

Step-by-step explanation:

To properly apply the substitution method, it will be better for us to rearrange the system of equations to have similar variables on the same side

$44 - 4 = -2y ----equation 1$

$10 = 7x + 4y --- equation 2$

We can simply evaluate equation 1 to have

$40 = -2y\\y = 40/-2 = -20\\$

y = -20

From the first equation alone, we can evaluate the value of y as -20. This is because only one unknown is present in equation one, hence a single equation is sufficient enough to evaluate it. If to unknowns were present, the two equations would have been utilized to evaluate the solution.
