Find the 63rd term of the arithmetic sequence

Elanso [62]

Answer:

443

Step-by-step explanation:

this can be put into the linear equation y = 7x + 2

substitute 63 for x

y = 7(63) + 2

simplify

y = 441 + 2

y = 443

the 63rd term is 443

hope this helps <3

The graph of a line passes through the two points (-2,1) and (2,1)

Vinil7 [7]

Answer: if you graph these points, you'll see that the line is horizontal, so the slope is zero. It will cross the y axis (y intercept) at y=1.

Step-by-step explanation:

Slope = y2-y1/x2-x1, so in this example:

m = 1-1/it doesn't matter because the answer will be zero!!

Now for slope intercept form:

y = mx + b

y = 0x + b; take one of your points and plug it in:

1= 0(2)+ b

1=0 + b

1=b

So your equation is:

y= 0(x) + 1

y=1

2. Abby found the axis of symmetry, x-coordinate, the vertex, and y-intercept

krek1111 [17]

Using quadratic function concepts, it is found that Abby made a mistake on the coordinates of the vertex, which are (-4,1).

----------------------

A quadratic function is defined by:

$y(x) = ax^2 + bx + c$

The y-intercept is given by point: $(0, y(0))$
The vertex is given by: $(-\frac{b}{2a}, y(-\frac{b}{2a}))$ .
The axis of symmetry is: $x = -\frac{b}{2a}$

----------------------

The function given is:

$f(x) = -x^2 - 8x - 15$

Which is a quadratic equation with: $a = -1, b = -8, c = -15$ .
$f(0) = -0^2 - 8(0) - 15 = -15$ , thus, the y-intercept is (0, -15).

$x_v = -\frac{b}{2a} = -\frac{(-8)}{2(-1)} = \frac{8}{-2} = -4$

Thus, the <u>x-coordinate of the vertex</u> is x = -4, which is the same as the <u>axis of symmetry</u>.

$f(-4) = -(-4)^2 - 8(-4) - 15 = 1$

The vertex is given by: (-4,1).
