Answer:
y = 1 [ y intercept (0,1) ]
x = -5/11 [ x intercept : (-5/11,0) ]
Explanation:
First split this compound equation into two seperate ones:
y = 11x + 6y = 11x + 6 →
{ y = 11x + 6y → -5y = 11x → [ y = -11/5x ]
[ y = 11x + 6 ] }
________
Then find the x point of intersection by substitution.
y = -11/5x → y = 11x + 6
-11/5x = 11x + 6
-11/5x - 11x = 6
-66x/5 = 6
-66x = 30
-11x = 5
x = 5/-11
x = -5/11
_______
Then find the y point of interesection by substituting the x solution in one of the equations.
x = -5/11 → y = -11/5x
y = -11/5(-5/11)
y = 55/55
y = 1
The x-intercept is x = - 6/11.
The y-intercept is y = 6.
What is an equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
Example:
2x + 3 = 9 is an equation.
We have,
y = 11x + 6
Now,
The x-intercept means y = 0.
So,
y = 11x + 6
0 = 11x + 6
11x = -6
x = - 6/11
The y-intercept means x = 0.
y = 11x + 6
y = 0 + 6
y = 6
Thus,
The x-intercept is x = - 6/11.
The y-intercept is y = 6.

1) 6a²x² - 7abx - 3b²=0, a is not equal to zero
pls answer
Answer:
b = b2-4ac
= (-7ab)^2 -4 (6a^2)(-3b^2)
= 49a^2b^2 + 72a^2b^2
= 121a^2b^2
Now, x = (7ab +- root 121a^2b^2)÷2(6a²)
= (7ab +- 11ab ) ÷ 12a²
= ( 20ab)/12a² or 4ab/12a²
= 5/3ab or - 1/3ab .
So, these are its roots .

Answer:
15
Step-by-step explanation:
Answer:
15
Step-by-step explanation:
When you are adding the absolute values of numbers the sign doesn't matter. So in this case the absolute value of 8 is 8. It is 8 units away from 0. The absolute value of -7 is 7, meaning it is 7 units away from 0. With this in mind you can add both of these numbers together as if they were positive. So 7+8

Step-by-step explanation:
A full line must be 180 degrees and you already know that part of the line is 66 degrees. You do 180 minus 66 which gives you 114. That is the other unknown angle but it is asking for x, not the angle. You do 114 divided by 6 to get 19. Therefore, x=19.

What is the fundamental principle of multiplication?Multiplication is the mathematical operation that is used to determine the product of two or more numbers. If an event can occur in m different ways and if following it, a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.
Given that sporting goods store is offering a 20% discount on shoes. Mariana also has a $5 off coupon that can be applied to her
purchase.
She is planning to buy a pair of shoes that originally costs = $89.
The discount price is the same either way.
Thus 20 percent of $89.00= 17.80$
Therefore, we have;
$89.00 - ($5.00 x $17.80) = $66.20
$89.00 - ($17.80 x $5.00) = $66.20

Find the slope of a line through the given points.
(3-7), (5,5)
Answer:
11/2
Step-by-step explanation:
Answer: m = 6
Step-by-step explanation: Start by writing down the slope formula.
m = y₂ - y₁ / x₂ - x₁
We take the second y minus the first y over the second x minus the first x.
m = 5 - (-7) / 5 - 3
m = 12 / 2
m = 6
So the slope of our line is 6.
