An unknown quantity is called a variable.

We typically use letters (ie: x) to represent these unknown values.

PLS HELP WILL GIVE BRAINLIEST
andreyandreev [35.5K]

The guts of the table are ...

\left[\begin{array}{cccc}x&y&x+y=85&y=2x+4\\19&65&\text{false}&\text{false}\\25&60&\text{true}&\text{false}\\27&58&\text{true}&\text{true}\\32&53&\text{true}&\text{false}\end{array}\right]

Of course, you know the answer after figuring the third line of the table.

The two numbers are 27 and 58.

_____

If the second number is odd, the result after subtracting 4 will not be divisible by 2. This lets you reject the 1st and 4th choices immediately. As for the second choice, twice 25 is 10 less than 60, not 4 less, so that choice can also be discarded.

Starting from the system of equations

x+y=85\\y=2x+4

you can use substitution to get

x+(2x+4)=85\\\\3x=81\qquad\text{subtract 4}\\\\x=27\qquad\text{divide by 3}

This identifies the 3rd selection as the appropriate one.

WILL GIVE BRAINLIEST!!!!!!!
lara [203]
Paralell has same slope
slope of ax+by=c is -a/b
so a paralalell line to ax+by=c is ax+by=z where a=a and b=b and z is a constant

so
paralalel to 3x-2y=-6 is 3x-2y=?
find ?
given point (4,2)
sub
3(4)-2(2)=12-4=8

equation is 3x-2y=8
solving for slope itnercept or y
minus 3x both sides
-2y=-3x+8
divide by -2
y=3/2x-4

B is answer

Evaluate the given expression. Subscript 5 Baseline P Subscript 2 a. 40 c. 25 b. 32 d. 20
Leto [7]

Answer:

d. 20

Step-by-step explanation:

The given question implies 5 permutation 2, i.e _{5}P_{2}.

But,

_{n}P_{r} = \frac{n!}{(n - r)!}

So that for _{5}P_{2}, n = 5 and r = 2.

_{5}P_{2} = \frac{5!}{(5 - 2)!}

     = \frac{5!}{3!}

    = \frac{5*4*3*2!}{3*2!}

Cancel out 3 and 2 with respect to the numerator and denominator.

_{5}P_{2} = 5 * 4

     = 20

Therefore,

_{5}P_{2} = 20

So that the correct option is D.
