Find the value of two numbers is their sum is 21 and their difference is 3
kobusy [5.1K]

Hello from MrBillDoesMath

Answer:   12, 9

Discussion:

Let x be the first number and y the second number. The form the problem statement:

x + y = 21

x - y = 3


Add the two equations. This gives:

(x + x ) + ( y-y) = 21 + 3 =>

2x + 0 = 24 =>

x = 12

Since x -y =3, substituting in the value of x gives,  12 - y = 3 so y = 9


Thank you,

Mr. B

Answer:

<h2>3.05x(output for x)</h2><h2>39.65</h2>

Step-by-step explanation:

<h3>to understand this</h3><h3>you need to know about:</h3>
  • function
  • PEMDAS
<h3>let's solve:</h3>

according to the question

the function is

f(x)=3.05x(first answer)

let's justify

f(1)=3.05×1

=3.05

LIKEWISE

f(3)=3.05×3

=9.15

therefore

it is the function

answer for the second question

f(13)=3.05×13

=39.65

Find the angle measures. Justify your responses.
MatroZZZ [7]

Answer:

m∠3 = 2x - 10° and m∠6 = 3x + 20

m∠3 = 58°          ;    m ∠6 = 122°

Step-by-step explanation:

a ║ b

m∠2 = m∠6                     If ║ cut by a transversal, then corresponding angles

                                         are ≅ and =

m∠7 = m∠3                   If ║ cut by a transversal, then corresponding angles

                                       are ≅ and =

m∠2 = 3x + 20              Given

m∠7 = 2x - 10                 Given    

m∠6 + m∠3 = 180°         If ║ cut by a transversal, then each pair of same-side

                                       interior angles (also called consecutive interior angles

                                       are supplementary (sum = 180°) .    

3x + 20 + 2x - 10 = 180°

5x + 10 = 180°

5x = 170°

x = 34°

Answer:   m∠3 = 2x - 10° and m∠6 = 3x + 20

                m∠3 = 2(34) - 10  ;    m∠6 = 3(34) + 20

                 m∠3 = 58°          ;    m ∠6 = 122°

What are the points for y =−7x−1?<br><br> I need the points!
harkovskaia [24]
You can find the x and y intercepts by plugging 0 in for each of the variables

(0)=-7x-1
1=-7x
x=-1/7

your x- intercept is (-1/7,0)

y=-7(0)-1
y=-1

your y-intercept is (0,-1)
