Answer:

v = (-4, -5)

Step-by-step explanation:

v2 + 9v + 13 = -7

v2 + 9v + 20 = 0

(v + 4)(v + 5) = 0

v = (-4, -5)

Answer:

-4,-5

Step-by-step explanation:

first set the equation equal to 0, v^2+9v+20, factor v^2+4v+5v+20, v(v+4) 5(v+4), so the 2 factors are (v+5) and (v+4), set both equal to that 0. v+5=0 v=-5 and v+4=0 v=-4, so the answer is -4 and -5

Y=5x-1<br>2x+y=13 how to solve​
ira [324]

Answer:

x = 2, y = 9 or (2,9)

Step-by-step explanation:

Hello!

The first equation "y = 5x - 1" is telling us that y is equal to 5x - 1

We can plug in the first equation into the second like this:

2x + y = 13 (we know y so we can plug it in)

2x + (5x - 1) = 13

2x + 5x - 1 = 13

7x - 1 = 13

Now we add 1 to both sides

7x - 1 + 1 = 13 + 1

7x = 14

x = 2

Now we plug in x to find y:

y = 5x - 1

y = 5(2) - 1

y = 10 - 1

y = 9
