Sum of an infinite geometric sequence with the common ratio r, and the first term a1 is $\frac{a_1}{1-r}$

we notice
-2 times -1/4=1/2,
1/2 times -1/4=-1/8
so a1=-2
r=-1/4 or -0.25

so the sum is
$\frac{-2}{1-(-0.25)}$ =
$\frac{-2}{1+0.25}$ =
$\frac{-2}{1.25}$ =
$\frac{-8}{5}$ =
the sum is -8/5 or -1.6

Find the gradient of the line passing through (6,8) and (4,10)

Mariulka [41]

Question:

Find the gradient of the line passing through (6,8) and (4,10).

Answer:

-1 is the right answer.

Step-by-step explanation:

Slope of the line = The gradient of the line

Gradient of the line is known as change in the value of y-axis by change in the value of x-axis

Gradient = ∆y\∆x

$Gradient = \frac{y_ 2 - y_1}{x_2 - x_1} = \frac{(10 - 8)}{(4 - 6)} = \frac{(2)}{(- 2)} =\boxed{- 1}\\$

Solve for a and graph the solution on the number line below.

oksian1 [2.3K]

Solve for x and graph the solution on the number line below.

$-x-5 \geq 1 \text { or }-x-5 < -8$

$-x-5 \geq 1$

Add 5 to both sides

$-x-5+5 \geq 1+5$

Simplify

$-x \geq 6$

Multiply both sides by - 1 (reverse the inequality) $(-x)(-1) \leq 6(-1)$

Simplify

$x \leq-6$

$-x-5 < -8$

Add 5 to both sides

$-x-5+5 < -8+5$

Simplify

$-x < -3$

Multiply both sides by $-1$ (reversing the inequality)

$(-x)(-1) > (-3)(-1)$

Simplify

$x > 3$

The idea of inequality, which is the state of not being equal, especially in terms of status, rights, and opportunities, is at the core of social justice theories. However, because it frequently has diverse meanings to different individuals, it is prone to misunderstanding in public discourse. However, certain distinctions are universal.

In mathematics, inequalities specify the connection between two non-equal numbers. Equal does not imply inequality. Typically, we use the "not equal sign (≠)" to indicate that two values are not equal. But several inequalities are utilized to compare the numbers, whether it is less than or higher than.
