Answer:
55 - you multiplied 6 by 11 to get 66 so you multiply by 5 by 11 to get 55.
Answer:
The y-intercept is at y = 10.
Step-by-step explanation:
It will be between y = 14 and y = 7 because the corresponding x values are -2 and 1.
An increase of 3 units of x gives a decrease of 6 units of y fro the above values.
Then an increase of 1 ( 1 to 2) in x gives decrease in y of 2 (8 to 6). The other values show the same pattern.
So very unit increase in x, the y values change by -2.
So from x = -2 to 0 is +2 units for x and this will be -4 units for y so the y-intercept ( when x = 0) will be at y = 14-4 = 10
y-intercept is (0,10).
Answer:
Step-by-step explanation:
To solve this equation, we must isolate the variable (x) using inverse operations.
x-2 is being multiplied by -3. The inverse operation of multiplication is division, so we divide both sides by -3.
2 is being subtracted from x. The inverse operation of subtraction is addition, so add 2 to both sides of the equation.
In this equation, x is equal to 0.
I will. But one question is it Grade 8 math
Answer:
y = a + b x + c .
Step-by-step explanation:
Also (How to do it!):
We can find the vertex of a quadratic equation with these steps:
Get the equation in the form y = ax2 + bx + c.
Calculate -b / 2a. This is the x-coordinate of the vertex.
To find the y-coordinate of the vertex, simply plug the value of -b / 2a into the equation for x and solve for y.
