Which point is on the line y=-2+3? (-2,-1) (3,3) (3,-3) (-3,-9)

puteri [66]

Answer:

The point (3, -3) is on the line.

Step-by-step explanation:

In order to find if it is a solution, input the numbers into the appropriate places in the equation.

y = -2x + 3

-3 = -2(3) + 3

-3 = -6 + 3

-3 = -3

How do you solve this

PilotLPTM [1.2K]

Since 3=30/10, (30+1)/10=31/10. 31s/10=(30+1)/5 ( we get 30 because 5*6=30) = 31/5. Multiplying both sides by 10, we get 31s=62 (since 5 is a factor of 10, we can do 10/5 =2 and multiply 2 by 31). Dividing both sides by 31, we get s =2

(x^3−7x−6) : (x−4)<br> Kan someone solve this for me, and show how to get it?

Vladimir79 [104]

Answer:

x = 3 or x = -1 or x = -2

Step-by-step explanation:

Solve for x:

(x^3 - 7 x - 6)/(x - 4) = 0

Hint: | Multiply both sides by a polynomial to clear fractions.

Multiply both sides by x - 4:

x^3 - 7 x - 6 = 0

Hint: | Factor the left hand side.

The left hand side factors into a product with three terms:

(x - 3) (x + 1) (x + 2) = 0

Hint: | Find the roots of each term in the product separately.

Split into three equations:

x - 3 = 0 or x + 1 = 0 or x + 2 = 0

Hint: | Look at the first equation: Solve for x.

Add 3 to both sides:

x = 3 or x + 1 = 0 or x + 2 = 0

Hint: | Look at the second equation: Solve for x.

Subtract 1 from both sides:

x = 3 or x = -1 or x + 2 = 0

Hint: | Look at the third equation: Solve for x.

Subtract 2 from both sides:

Answer: x = 3 or x = -1 or x = -2

What is the range of the discrete finite function F(x)?

Whitepunk [10]

Answer:

$Range = \{4,7,9\}$

Step-by-step explanation:

Given

The attached function

Required

The range of the function

A function is represented by matching an arrow from the domain to the range.

This implies that, the arrow comes from the domain to the range

From the attached function, the arrow points to 4,7 and 9

Hence, the range is:

$Range = \{4,7,9\}$
