Answer:

I sure hope none is an answer because none of these work!

Step-by-step explanation:

C = 59 (F - 32)

(C/59) = F - 32

F = C/59 + 32

So no :(

m = x + y + z3

y = m - x - z3

So no :((

s = r^2 - 1

r = sqrt(s+1)

So no :000

A = 12(a+b)

A = 12a + 12b

12b = A - 12a

b = A/12 - a

So no :00(((

m = x + y^2

y = sqrt (m-x)

AND no :|

The sum of two integers is 61 and their difference is 1. Find the integers.
musickatia [10]

We can find this integer using a system of equations.  The first thing we look at is the first sentence.

Let's call X The first integer,

Let's call Y the second integer.


So, X+Y=61 and X-Y= 1


Using Substituion on the second equation, we get

X=Y+1

(Now we plug in Y+1 into the second equation for X)

So,

(Y+1)+Y=61

2Y=60

Y=30

So, one of the integers is 30.

Now to find the second, we go back to

X=Y+1

X=30+1

X=31.


So, the integers are 31 and 30.


Hope this helps!

Whats the answer? Please help
PolarNik [594]

Answer:

Answer: y=3/2x+1

To find a line that is perpendicular, invert the slope and multiply by -1

so the original slope is -2/3,

invert it to get -3/2 then multiply by -1 to get 3/2

Put the given point (-2,-2) and the new slope into point intercept form: y+2=3/2(x+2)

Rewrite in standard form to get y=3/2x+1
