7x+9y=-41 and x+3y=1. Solve system of equations

galben [10]

9514 1404 393

Answer:

(x, y) = (-11, 4)

Step-by-step explanation:

You can subtract 3 times the second equation from the first to eliminate y.

(7x +9y) -3(x +3y) = (-41) -3(1)

4x = -44

x = -11

Substituting into the second equation gives ...

-11 +3y = 1

3y = 12

y = 4

The solution is (x, y) = (-11, 4).

What is the value of x if HF = 4x+1 and AB = 12x-3?| Given m

Reptile [31]

Answer: x = 1.25

Step-by-step explanation:

HF - is the middle line of the triangle ABC.

$HF=\dfrac{1}{2} AB\\\\HF=4x+1\\AB=12x-3\\\\4x+1=\dfrac{1}{2} \cdot (12x-3)\\\\4x+1=\dfrac{12x-3}{2} \\\\(4x+1) \cdot 2 =12x-3\\8x+2=12x-3\\8x+2-12x=12x-3-12x\\-4x+2=-3\\-4x+2-2=-3-2\\-4x=-5\\-4x \cdot (-1)=-5 \cdot (-1)\\4x=5\\4x \div 4=5 \div 4\\x=1.25$

Pls help 40 points this is my last chance to get extra points pls serious answers

Alja [10]

Answer:

I think it is A or D

Step-by-step explanation:

I dont know because for a range to be determined, you must go at where the lowest point the function goes and the highest point it reaches, and the lowest is 250,000 and the highest is 1,000,000 but it says

250,000 < y < 1,000,000 and the A option says 0 < x < 110, I dont know but it is not b and c, I'm sorry if I'm wrong
