Answer:
<h2>Explanation:</h2><h2>You know that when x = 0, y = -7 (because y = 4(0)-7 = -7, or you just know the fact that the constant number shows the y-value of the y-intercept). Therefore, you can plot that point on the graph:</h2>
<span>Nonlinear negative association
The graph is by no means linear. You can see that it has a bit of curve near the beginning.
Also, if you were to find the slope of the mainly linear line, you would find that it has a negative slope. You can also tell that it is negative because the y-values are decreasing as x values are increasing. And the slope is found by change in y over change in x. Therefore, the slope would be negative.

Didnt feel like doing them all , i only attempted to answer the first one which is " a " ( -6 ) hope i helped :)
Answer:


Step-by-step explanation:

Ignore the A before the ±. It wouldn't let me type it correctly.
x² + 2x - 5 = 0
a = 1
b = 2
c = - 5









Two separate equations




Answer:
x = 4
Step-by-step explanation:
We assume that the given expessions represent the measures of the alternate interior angles, so are equal.
... (4x + 12)° = 7x°
... 12 = 3x . . . . . . . divide by degrees, subtract 4x
... 4 = x . . . . . . . . . divide by 3
_____
Then the angles are 7x° = 28° = (4x+12)°.
