Graph 3x + 4y = 12. y

Mathematics
1 answer:
Tema [17]3 years ago
3 0

Answer:

  see below

Step-by-step explanation:

To find the x- and y-intercepts, set each of the variables to zero and solve for the other:

  y-intercept: 0 +4y = 12   ⇒   y = 12/4 = 3

  x-intercept: 3x +0 = 12   ⇒   x = 12/3 = 4

Plot these points (0, 3) and (4, 0), and draw a straight line through them.

Is F(x)= X^2(X^2+9)(X^3+2X) even or odd
dexar [7]

Answer:

The function is odd.

Step-by-step explanation:

A function is even if the graph of the function is symmetric with respect to the y-axis. A function is odd if the graph of the function is symmetric with respect to the origin. To find if the function is even or odd, we're going to graph the function using DESMOS.

As you can see in the attached picture, the function is symmetric with respect to the origin. Therefore, the function is odd.

Find the number that makes the 2 fractions equivalent 3/8=9/?
Lorico [155]

Answer:

24

Step-by-step explanation:

The numerator of the equivalent fraction of 3/8 is 9. From this, we can see that the common factor that is being multiplied is 3. So the denominator, 8, has to be multiplied by 3 as well which gives you 24. 9/24 is an equivalent fraction of 3/8

Triangle ABC had a perimeter 18 cm
Anna007 [38]

Answer:

Use pythagoreum theorem to determine whether it is or isn't since I'm not really sure myself but here's my calculations.

Step-by-step explanation:

We need to find AC.

Picture a triangle called ABC. AB is one side and BC the other while AC is the hypotenuse.

AC=

ac =  \sqrt{ab ^{2}  +  {bc}^{2} } \\ ac = \sqrt{ {7}^{2} }  +  {3}^{2}  \\ ac =  \sqrt{49 + 9}  \\ ac =  \sqrt{58 }  \\ ac = 7.6

Round up the 7.6 to a whole number and you get AC=8. To get perimeter of a triangle simply add the sides together to get 18.

Not really sure about my answer but hope this helped.
