It is no solution, bc the answer is (0,0)
RoseWind [281]3 years ago
6 0

Answer:

one solution (0,-1)

Step-by-step explanation:

y=5x-1

-15x-3y=3

LEts solve for x  and y, Substitute  5x-1 for y in second equation

-15x-3y=3

-15x-3(5x-1)=3

-15x-15x+3=3

Combine like terms

-30x+3=3

Subtract 3 on both sides

-30x=0

Divide both sides by -30

x=0

Now plug in 0 for x in first equation

y=5x-1

y=5(0)-1=-1

So one solution (0,-1)

Which of the following shows the division problem below in synthetic division form? 4x^2-13x+8 / x+5
Tju [1.3M]

Answer:

Dividing 4x^2 - 13x + 8  by x + 5 or x - (-5), in synthetic division form:

-5)        4          |       -13      |          8

           ↓               4 x (-5)     (-5) x (-33)  

           4                 -33               173

=> Quotient is 4x - 33 and remainder is 173

=> (4x^2  - 13x + 8)/(x + 5) = (4x - 33) + 173/(x + 5)

Hope this helps!

What is the value of a? <br> 14 – 2a = 4a – 16
VladimirAG [237]
14 - 2x = 4a - 16

First, add 2a to both sides. / Your problem should look like: 14 = 4a - 16 + 2a
Second, simplify 4a - 16 + 2a to get 6a - 16. / Your problem should look like: 14 = 6a - 16
Third, add 16 to both sides. / Your problem should look like: 14 + 16 = 6a
Fourth, add 14 + 16 to get 30. / Your problem should look like: 30 = 6a
Fifth, divide both sides by 6. / Your problem should look like: \frac{30}{6}  = a
Sixth, 6 goes into 5 to get 30, so simplify \frac{30}{6} to 5. / Your problem should look like: 5 = a
Seventh, switch your sides. / Your problem should look like: a = 5

Answer: a = 5
