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

Mathematics

Answer:

(8, -22) All real numbers

Step-by-step explanation:

So since we already have the value of y lets Substitute;

3x + (-4x + 10) = 2

Distribute;

3x - 4x + 10 = 2

Collect like terms;

-1x + 10 = 2

Subtract 10 from both sides;

-1x = -8

Divide both sides by -1

x = 8

So now lets get the actual value for y by substituting x;

y = -4(8) + 10

y = -32 + 10

y = -22

(x, y) = (8, -22)

Find 4 consecutive even integers whose sum is 156?
snow_tiger [21]
X+(x+1)+(x+2)+(x+3)=156
4x+6=156
4x=150
x=37.5 (not an integer)
If x=37 you get 37+38+39+40=154 and if x=38 you get 38+39+40+41=158[/tex]

Which of the following is a solution of x2 + 2x + 8?
zubka84 [21]
Using the quadratic equation we get:
\frac{ - 2 + - \sqrt{4 - 32} }{2} = \frac{ - 2 + - \sqrt{ - 28} }{2}

Factoring out 2 we get
\frac{ - 2 + - 2\sqrt{ - 7} }{2} = - 1( + - ) \sqrt{ - 7}
Factoring out the imaginary number:
- 1 + \sqrt{7} i \: (and) \: - 1 - \sqrt{7} i
So b.
