Answer: (-10, 46)

Step-by-step explanation:

The given solution of the system of equations :-

y=-4x + 6-----(1)\\\\ y = -5x -4-------(2)

Subtract (2) from (2), we get

0=-5x-(-4x)-4-(6)\\\\\Rightarrow\ 0=-5x+4x-4-6\\\\\Rightarrow\ 0=-x-10\\\\\Rightarrow\ x=-10

Put value of  x in (1) , we get

y=-4(-10) + 6=40+6=46

Hence, the  solution of the system of equations = (-10, 46)

Y= -4x + 6 (-10, 46), (-1.11, 10.44),

y= -5x -4. (-10, 46)

whereas (-10, 46) is the solution for both equations, it is the correct choice

Sarah rolls a die twice. What is the probability that she rolls a 3 and then an even number?
egoroff_w [7]
1/12

This is because she has a 1/6 chance of getting a 3 on the first try and then a 1/2 chance of getting an even on the second. Multiply these two together to get your answer.

Aneli [31]
Slope of f(x)


Slope of g(x)


PART A)
The slopes of f(x) and g(x) are the same.

PART B)
The equation for line f(x)
y = 4x + b
-1 = 4(0) + b
-1 = b

y = 4x - 1

The function G(x) has a bigger y-intercept. The y-intercept of g(x) is 3, while the y-intercept of f(x) is -1.
