Mathematics
1 answer:
vova2212 [387]3 years ago

Answer:

Step-by-step explanation:

Quadratic function is a function that can be described by an equation of the form fx = ax2 + bx + c, where a ≠ 0.

Example:

1. Use the graph of y = x2 + x - 6 to solve x2 + x - 6 = 0.

2. Use the graph of y = -x2 + 4 to solve -x2 + 4 = 0.

3. Use the graph of y = x2 -2x + 1 to solve x2 -2x + 1.

Graph the line that passes through the points (-1,7) and (-3,5) and determine
kari74 [83]

Answer:

y = x + 8

Step-by-step explanation:

find slope first:

m = 7-5 / -1-(-3)

m = 2 / 2

m = 1

now find the y-intercept using either ordered pair; plug 'y', 'x', and 'm' into

y = mx + b  to solve for 'b'

7 = 1(-1) + b

7 = -1 + b

8 = b

put 'm' and 'b' into slope-intercept equation of a line, y = mx + b to get:

y = x + 8

Can you use use the formula A = 1/2 x b x h to find the area of any triangle? Explain.
Morgarella [4.7K]
You can use it to find the area of a right triangle because a right triangle is basically a rectangle cut in half diagonally. However, this formula does not apply to all triangles because those that are not right triangles don't have a base or height, they're not really a rectangle. Because the formula for a rectangle's area is bxh, a right triangle is half of that. I hope this made sense and was helpful. :)

Option d is the only sentence in this format:

IF x = 5, THEN x² = 25

this statement is true --> 5² = 25
