Mathematics

2x - 3y = -2  ⇒ 4x - 6y = -4
4x +  y = 24 ⇒  <u>4x + y = 24</u>
                              <u>-7y</u> = <u>-28</u>
                               -7      -7
                                 y = 4
                     2x - 3(4) = -2
                       2x - 12 = -2
                       <u>     +12  +12</u>
                              <u>2x</u> = <u>12</u>
                               2      2
                               x = 6
                         (x, y) = (6, 4)

If f(x) = -3x4 - 2x3 + 3x2, and g(x) = 3x4 - 4x3 + x2 then f(x) + g(x) =
Alex_Xolod [135]
I'm assuming the the numbers coming after the variables are meant to be exponents, and if I'm wrong just let me know

-3x^4 - 2x^3 + 3x^2 + 3x^4 - 4x^3 + x^2, rearrange to have like terms in order
-3x^4 +3x^4 - 2x^3 - 4x^3 +3x^2 + x^2, now simplify
                0    -6x^3 + 4x^2

Find the common difference in the outputs to help find the missing outputs in the table
WINSTONCH [101]

Answer:

if you are trying to find the rest of A it would be adding by 1 because of the slope so: 5,6,7,8,9,10. The slope of B wouldbe .8 because it is increasing by .8 everytime so: 3.8,4.6,5.4,6.2,7.0

Step-by-step explanation:

B) 4.6-3.8= .8

5.4-4.6= .8

slope is .8

5.4+.8=6.2

6.2+ .8= 7.0

Cab companies often charge a flat fee for picking someone up and then charge an additional fee per mile driven.
Dahasolnce [82]
1a.)  y=0.5x+2
1b.)  The 0.5x is the slope. It represents the amount of extra money you are paying (in addition to the automatic $2) per mile. The y-intercept is 2. That represents the amount you automatically pay for that company.

2.a) I forgot how to do point-slope form, but for 2b., the slope is representing the same thing as in 1a. The slope is .65 and it is representing the amount of money you pay (in addition to the automatic $1.75) per mile.

To find the answers to the table question, use the slope intercept formula, y=.65x+1.75 Plug the numbers they are asking about in for x.

Example: Plugging in 3 we get y=(.65)(3)+1.75 which will equal 3.7 so the amount of money you pay after driving for 3 miles is $3.70.
