In case of plane, for y intercept, x and z are o .

So we will get

4(0)+5y-0=20

5y=20

Dividing both sides by 5

y = 4

So the y intercept is (0,4,0).

In second question, x intercept is 1, y intercept is -1 and z intercept is 2 .

So the correct option is the third equation , that is x-y+2z=4 .

Answer:

Option c and

Option d

Step-by-step explanation:

Given is a plane 4x+5y-z=20

To find y intercept

In the y axis x=0=z

Substitute to get5y =20:\\y=4

Hence point is (0,4,0)

2) When x intercept = 1, y int =-1 and z int =2 we have in intercept form the plane

\frac{x}{1} +\frac{y}{-1} +\frac{z}{2} =1\\2x-2y+z=2

is the right one

Option d

Find the measure of each marked angle!!
tamaranim1 [39]

Answer:

60 is the answer

Step-by-step explanation:

10x - 20 = 7x + 4 (Corresponding angles)

10x - 7x = 20 + 4

3x = 24

x = 8

substituting the values,

10(8) - 20

80 - 20

60

similarly the other angle is 60 since they are corresponding angles.

For what value of q is in the question -13(q+4)=7q+16​
Rufina [12.5K]

Answer:

q=-3 2/5

Step-by-step explanation:

First multiply -13 with (q+4)

-13q-52=7q+16

Now you have to change the order before = the numbers with q and after = the numbers without anything

-13q-7q=52+16

Remember that when you change positions the symbol too

Then solve it

-20q=68

Now u have to divide as i do

q=68/-20

you can simplify it

q=3 8/-20

Now divide by the greater divisor in this case is 4

q=3 2/-5

And organize it

q=-3 2/5

Never forget to do q=(answer)

Hopefully it helps.
