The sum of two numbers is

bekas [8.4K]

Okay you have 2 sum unknow lets call them X+Y

so X+Y=33, 4X=108

Get X by it self then plug it in 4X=108

X=-Y+33
4(-y+33)= 108
-4y+132=108 Then subtract the 132
-4y=-24 Y=6 then to find X subtract 33-6=27
Y=6 X=27 if you check it works out

Find the equation of a line perpendicular to y - 3x = – 8 that passes through the point (3, 2). (answer in slope-intercept form)

Ymorist [56]

Perpendicular means that you will flip and change sign in this case we have -3 when we flip it and change sign we will get 1/3
So,

First we have to find b:

2=1/3(3)+b
2=1+b
1=b

Second you just write your equation:

Y= 1/3x + 1

Hope it help sweetheart!!

The system of equations is coincident. What are the missing values?

telo118 [61]

Coincident lines are lines that are the same.

In the beginning of both equations we have '4x' and '8x'.

Note that 8 / 4 = 2.

Multiply the rest of the numbers in the first equation by 2.

5y * 2 = 10y

8 * 2 = 16

So our 2nd line will be:

8x + 10y = 16

The metal in the penny is worth about 0.505 cent. how many cents is this written as a fraction

GuDViN [60]

To solve this you simply divide .505 by 1 (0.505/1) and then multiply by 1000/1000 to get rid of the decimal, giving you 505/1000. If you want to return to decimal form you divide 505 by 1000.

Hope this helps!

Pls help I’ll brainlest for correct answer you gotta graph it on the graph too

Ipatiy [6.2K]

Answer:

Slope: -2/3

Y Intercept: 0,-3

Step-by-step explanation:

To find the slope, use the formula (y1-y2)/(x1-x2)

(1-(-1))/(-6-(-3))

-2/3

So the slope is: -2/3

If the slope is 3/2, then the using the formula of y=mx+b, we can find the y intercept (b)

y = -2/3x + b

insert any point of x and y

-1 = -2/3(-3)+b

-1=-2+b

so b = -3

thus, the Y intercept is 0,-3
