Answer:

120°

Step-by-step explanation:

The angle just below 'x' is 40° (alternate angles/parallel lines)

40 + x + 20 = 180 ( straight line)

x = 120°

5, 3.1.24<br><br> f(x) = 3x² + 5; find f(x + 3) - [f(x) + 3]

Aleks [24]

Given that $f(x) = 3x^2 + 5$ , we have

$f(x + 3) = 3 (x + 3)^2 + 5 \\\\= 3 (x^2 + 6x + 9) + 5 \\\\= 3x^2 + 18x + 32$

so that

$f(x+3) - (f(x) + 3) = (3x^2 + 18x + 32) - (3x^2 + 8) \\\\= \boxed{18x + 24}$

A line intersects the points

kari74 [83]

Answer:

$\boxed{\sf m=\boxed{8}}$

Step-by-step explanation:

To determine the slope of a line given the coordinates of two points on the line, use the slope formula.

$\boxed{\sf \mathrm{m}=\cfrac{y_2-y_1}{x_2-x_1}}$

x1 and y1 are the coordinates of the first point. The second point's coordinates are x2, y2.

$\Box \:\:\sf Points:(6,-4)\:and (7,4)$

$\leadsto\sf \left(x_1,\:y_1\right)=\left(6,\:-4\right)$

$\leadsto\sf \left(x_2,\:y_2\right)=\left(7,\:4\right)$

______________

$\longmapsto\sf m=\cfrac{4-\left(-4\right)}{7-6}$

$\longmapsto\sf m=8$
