What is the equation of the line perpendicular to 2x+5y=202x+5y=20 and containing the point (10,−4)(10,−4)?

1 answer:

6 0

2x + 5y = 20
5y = -2x + 20
y = -2/5x + 4. The slope here is -2/5. A perpendicular line will have a negative reciprocal slope. To find the negative reciprocal of -2/5, we flip the slope and change the sign. So our perpendicular line will have a slope of 5/2.

y = mx + b
slope(m) = 5/2
(10,-4)....x = 10 and y = -4
now we sub and find b, the y int
-4 = 5/2(10) + b
-4 = 25 + b
-4 - 25 = b
-29 = b

so our perpendicular equation is : y = 5/2x - 29 <==

Find the value of x 12x 6x+28 Your answer

Irina18 [472]

Step-by-step explanation:

Hey there!

By looking at the figure, the given "2x" and "6x + 28" are co-interior angle.

So,

2x + 6x + 28 = 180°. ( sum of co-interior angle is 180°)

8x + 28°=180°

8x = 180° - 28°

8x = 152°

$x = \frac{152}{8}$

X = 19°

Therefore, X = 19°.

Hope it helps...

If x and y are 2 complementary angles then find the value of y if measure of angle x is 20 degree

schepotkina [342]

Answer:

y=70 degrees

Step-by-step explanation:

If 2 angles are complimentary, they add up to 90 degrees.

x+y=90 degrees

x=20 degrees

y=90-20 degrees

y=70 degrees

If that is wrong, try this. Let's say the questions gives us the fact that x is 20 degrees greater than y.

y=x

Substituting x for y, the equation is x+x+20=90

Since y is x, x would also be y, which is 35. then x+20 would be 55.

So y would be 35.

THE ANSWER WOULD BE 70 DEGREES, BUT IF THAT IS WRONG, DO THE SECOND ONE, WHICH IS 35

Answer:-m or m+3

Step-by-step explanation:

$x^{2} -3x -(m^{2}+3m) =0\\\\x^{2} -3x -m^{2} -3m=0\\$

$x^{2} -m^{2} -3x - 3m=0$

Applying difference of two squares

⇒( $x^{2} -m^{2}$ )=(x+m)(x-m)

Substituting this for ( $x^{2} -m^{2}$ )

Factorising -3x-3m=-3(x+m)

(x+m)(x-m)-3(x+m)=0

since we have double (x+m),we'll pick one

⇒(x+m)=0

or (x-m-3)=0

⇒x=-m or x= m+3

PLEASE HELP ME YOU WILL GET A LOTT OF POINTS PLEASE!!!!

abruzzese [7]

Answer:

h = 6 hours, A = $210

Step-by-step explanation:

The equation for Lady Luck Limousine's (LLL) total amount is A = 25h + 60, where h represents the hours.

The equation for Street Scene Limousine's (SSL) total amount is A = 35h.

To find the point at which the two services would be equal, we can use the equation 25h + 60 = 35h.

Solving for h = 6.

When we plug in 6 into either one of the equations, we get $210.
