Answer:

y = $\frac{1}{2}$ x + 1

Step-by-step explanation:

I'm guessing you're missing an x and the equation is: y = -2x +2, based on that:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y-intercept )

y = - 2x +2 is in this form

with slope m = - 2

The slope of a perpendicular line is the negative reciprocal of m, so

$-2=\frac{-2}{1}$ so the $m_{perp} = \frac{1}{2}$

(0 , 1 ) is the y-intercept ⇒ c = 1

y = $\frac{1}{2}$ x + 1 ← equation of a perpendicular line

You need 660 mL of a 40% alcohol solution. On hand, you have 35% alcohol mixture. You also have a 95% alcohol mixture. How much

ozzi

Answer:

A. 605 mL of the 35% solution

B. 55 mL of the 95% solution

Step-by-step explanation:

It is given that, you need 660 mL of a 40% alcohol solution. On hand, you have 35% alcohol mixture. You also have a 95% alcohol mixture.

Let x and y be the amount of 35% alcohol solution and 95% alcohol solution (in mL) respectively.

So,

Amount equation: $x+y=660$ ...(1)

Alcohol equation : $0.35x+0.95y=0.40(660)\Rightarrow 0.35x+0.95y=264$ ...(2)

On solving (1) and (2), we get

$0.35(660-y)+0.95y=264$

$231-0.35y+0.95y=264$

$0.6y=264-231$

$y=\dfrac{33}{0.6}$

$y=55$

Now, substitute y=55 in (1).

$x+55=660$

$x=660-55$

$x=605$

Therefore, we need 605 mL of the 35% solution and 55 mL of the 95% solution.

Two solid metal spheres have masses of 5 kg and 135 kg respectively. If the radius of the smaller one is 4 cm, find the radius o

Cerrena [4.2K]

Answer: 12 cm

Step-by-step explanation:

The masses of the spheres are proportional to their volums, and the cube of the ratio is k^3=135/5=27 ==> k=3

The greater radius is 3*4=12 (cm)

What is the quotient of 8/9 and 1 1/3

Art [367]

Hello,

To divide by a fraction, multiply by its reciprocal.

Solution:

8/0 x 3/11

The greatest common factor is 3; cancel 3 out.

The problem will simplify to 8/33.

Is it possible to have more than one (x,y)(x,y) pair that is a solution to both equations? Explain or show your reasoning

lesya692 [45]

Answer with step-by-step explanation:

Yes, it is possible to have more that one (x,y) pair because of the distributive property.

6x + 4y = 34. If this is the case, we have to find 2 numbers that sum up to 34.

x = 3

y = 4

5x - 27 = 15. If we are going to calculate this equation, you need to reverse the equation. 15 + 27 = 42 = 5x. If 42 = 5x, we have to divide 42 by 5, which is 8.4

Hope this helped! (brainliest please)
