Step-by-step explanation:

x = -10, y = 10

y= -4x+4

m1×m2 = -1

-4 × m2 = -1

m2 = 1/4

y-y1 = m(x-x1)

y-10 = 1/4(x+10)

y-10 = 1/4x +10/4

(×4)

4y-40=x+10

4y=x+50

x-4y+50=0

tensa zangetsu [6.8K]

Answer:

3 feets

Step-by-step explanation:

Given that :

Entire walkway uses 6 feets of brick

Width of walkway = x

Width of walkway is the same along both sides ;

SINCE, the number of sides of the walkway = 2 and each side is the same

Hence,

x + x = 6 feets

2x = 6 feets

x = 6 feets / 2

x = 3 feets

Plz Q-Q<br> convert 3/5 into a fraction with a denominator of 20

Aliun [14]

Answer:

$\frac{12}{20}$

Step-by-step explanation:

Lets think about multiplication. What times 5 equals 20? (5x = 20)

It would be 4! (5 x 4 = 20)

So take the 4 and multiply it by the fraction.

$4 * \frac{3}{5} = \frac{4}{4} * \frac{3}{5} = \frac{12}{20}$

Theres your answer :)

The cost, C(x),for manufacturing x units of certain product Is given byC(x)=x^2-20x+35, find the units manufactured at a cost of

Rainbow [258]

Answer:

No units

Step-by-step explanation:

The cost function is given by;

$C(x)=x^2-20x+35$

To find the units manufactured at a cost of $5,560

We equate the C(x) to 5560 and solve for x.

$x^2-20x+35 = 5560$

$x^2-20x+35 - 5560 = 0$

$x^2-20x - 5525= 0$

The discriminant of this equation is negative.

That is,

$d = {( - 20)}^{2} - 4 \times 1 \times - 5560 \: < 0$

Hence the equation has no real roots.

This means no units can be produced at $5,560

The temperature at 6:00 pm was 24°. At midnight the temperature 36° lower than 6:00pm . What was the temp at midnight?

horrorfan [7]

Answer:

-12°

Step-by-step explanation:

Man... I just did 36 minus 24, and since it says 36° lower I decided it was -12 degrees (24 - 36 is more accurate but I find it easier just to do it the other way)
