Answer:
Hence, the following equations, when graphed, intersect at the point (4, 0):
x - y = 4 (1)
x + y = 4 (4)
Step-by-step explanation:
<em>" For the graph to intersect at the point (4,0) we mean that when y=0 , x must be equal to 4 or we could say that when x=4 then y=0".</em>
1)
x-y=4
now when y=0 then x=4.
Hence, the graph intersect at the point (4,0).
2)
-x-y=4
When y=0 in the equation then x=-4, Hence the point (4,0) does not lie on the graph of the given function.
3)
2x-y=7
When y=0 then x=7/2.
Hence the graph of the function does not intersect at the point (4,0).
4)
x+y=4
When y=0 then x=4.
Hence the graph of the given function intersect at (4,0).
5)
2x + y = 7
When y=0 then x=7/2.
Hence the graph of the function does not intersect at the point (4,0).
6)
2x + y = -7
When y=0 then x= -7/2.
Hence the graph of the function does not intersect at the point (4,0).
Answer:
y=3x+5
Step-by-step explanation:
- start by putting 18x on the other side of the equation
- to do this you have to subtract, so it will be -18x now
2. now you have -6y=-18x-30
3. now you need to divide -6 by -18 and -30 on the other side to get y by itself
4. this will leave you with y=3x+5 because 6 divided by 18 is three and 30 divided by 6 is five.
I hope this helps!!
Answer:
1) This is because some has their own shape and the commonly used loop is the clothoid loop, e.t.c.
2) This is because researchers found out that it helps ease the passage of the kidney stones.

Hope it helps
Thanks.
11. to find <DAC a triangle will equal to 180° so subtract 100 and 32 from 180° which will give you 48.
12. is 145° not 35° because you add the two angles your given and and subtract from 180° a triangle will ALWAYS equal to 180°
13. To find <BAC a triangle will equal to 180° so subtract 88 and 57 from 180 which will give you 145°
14. is actually the same answers as 11 cause the the angle you need to find will always be the middle number which is the vertex. they both have the same vertex which is <A
15. will be the same as 11 as well.
16. <P will equal to 49.5
17 and 18. <B will actually be 90° if you see that square symbol it actually indicates it's a 90 degree angle. <A will be 48° and to find <C you add all the angles and subtract it by 180 which will give you 42°
hope this helps I'm taking geometry as well keeps practicing and this will get so easy. if you find any mistakes comment ❣
Answer:
and 
Step-by-step explanation:
We are asked that what are the zeros of the quadratic function f(x) = 6x² +12x -7.
So, we have to find the roots of the equation, f(x) = 6x² +12x -7 =0 ...... (1)
Since the quadratic function can not be factorized, so we have to apply Sridhar Acharya's formula.
This formula gives if, ax² +bx +c =0, the the two roots of the equation are
Therefore, in our case 'a' being 6, 'b' being 12 and 'c' being -7, the two roots of the equation (1) will be
= 
= and
Hence, x=
and x=
