What is the solution to the system of equations? y= 1/3x-10 2x + y = 4

Mathematics
1 answer:
Kipish [7]2 years ago

Answer:

(6, -8)

Step-by-step explanation:

Solve this system by substitution:  substitute (1/3)x - 10 for y in the second equation, obtaining:

2x + (1/3)x - 10 = 4, or (after multiplying both sides by 3):

6x + x = 42, or 7x = 42.

Then x = 6.  Substituting this into the first equation, we get:

y = (1/3)(6) - 10 = -8

The solution is (6, -8)

What is the equation of the line passing through the points (Two-fifths, StartFraction 19 Over 20 EndFraction) and (one-third, S
Elan Coil [88]

Answer:

You have to find the slope first. Which is y1-y1 divided by x1-x2

Then you find the y-intercept which you take the slope for m like for example if you find the slope, 2, then the equation should be y=2x+b. You take the coordinates on the problem and put them on the y or x on the equation. Then when you find the y-intercept you add it to the equation like for the example that I used above, you have to put the y-intercept on b. So if the y-intercept is 5 then the equation would be y=2x+5.

lilavasa [31]

Answer:

f(2) = 9

Step-by-step explanation:

It's give in the question,

Two different functions are,

f(x) = 4x + 1

g(x) = -2x

Then we have to find the output value of function 'f' for the input value x = 2.

By substituting the value of x in the function 'f',

f(2) = 4(2) + 1

     = 9

f(2) = 9

Number 8 please can you write and equation
tigry1 [53]
8.5x + 55 = 123

You would use the formula: mx + b = y

The slope is the amount of money each day(mx),and the y-intercept would be the fee(b) and the total cost would be y.
