Solve the equation.

Mathematics
1 answer:
elena55 [62]3 years ago
4 0

Answer:

C: x=-3 or x=4

Step-by-step explanation:

To solve the equation x^2-x-12=0 we need to factor it

We are looking for two numbers that when multiplied give -12 and when added give -x

This means that when factored, the equation would be (x-4)(x+3)=0

Now we can set each of these equal to 0, which means that at

x=-3 and x=4 , the equation will equal 0

Which of the following could be the graph of 3x + 4y = 12?​
Elan Coil [88]

Answer:

A graph that goes through (4, 0), (8, -3), (0, 3), and (-4, 6)

Step-by-step explanation:

Hello!

To find what this looks like it is easier to put it into slope-intercept form which is y = mx + b

To get our equation to look like that we have to get y by itself

3x + 4y = 12

Subtract 3x from both sides

4y = -3x + 12

Divide both sides by 4

y =- \frac{3}{4}x  + 3

We now know the y-intercept is (0, 3)

Now we follow the slope to give us more points

More points are (4, 0), (8, -3), and (-4, 6)

The answer would be a graph that goes through those points.

Hope this helps!

kati45 [8]
Answer:

The correct option is A

The missing number is 34

Explanation:

By inspection, the third number is obtained by adding the two preceding numbers.

1 + 1 = 2

The next number is obtained by adding the two preceding numbers.

2 + 1 = 3

This continues as:

3 + 2 = 5

8 + 5 = 13

13 + 8 = 21

21 + 13 = 34
