Which graph represents a line with a slope of -2/3

sertanlavr [38]

Answer:

$y=-\frac{2}{3} x-2$

Step-by-step explanation:

the general equation for a line is:

$y=mx+b$

where $m$ is the slope of the line, and $b$ is the y-intercept.

Since we need a slope of -2/3:

$m=-\frac{2}{3}$ ,

So far we have that the line must have the equation:

$y=-\frac{2}{3} x+b$

the graph of a line with a negative slope is one that "falls" from left to right in the plane. And the number $\frac{2}{3}$ means that it falls at a ratio of 2 units in the y-axis for every 3 in the x-axis.

we are told that the y-intercept is that of the line:

$y=\frac{2}{3} x-2$ --> here the y-intercept is -2.

Thus the equation of the line we are looking for is:

$y=-\frac{2}{3} x-2$

which means that this line crosses the y-axis at -2, and the graph is the one in the attached image.

10th term: a1 = 320,r=0.5

Strike441 [17]

Answer:

$a_{10}$ = $\frac{5}{8}$

Step-by-step explanation:

The n th term of a geometric sequence is

$a_{n}$ = $a_{1}$ $r^{n-1}$

Substitute in values

$a_{10}$ = 320 × $(\frac{1}{2}) ^{9}$

= 320 × $\frac{1}{512}$ = $\frac{320}{512}$ = $\frac{5}{8}$ = 0.625

The question is below:

Sonbull [250]

<h3>Hello There!!</h3><h2 /><h3><u>Given</u></h3>

$3(x - 2) + 7x = \frac{1}{2} (6x - 2)$

<h3><u>Solving </u><u>It</u></h3>

$3(x - 2) + 7x = \frac{1}{2} (6x - 2) \\ \\ \implies3x - 6 + 7x = ([\frac{1}{2} \times 6 \: x] - [\frac{1}{2} \times 2]) \\ \\ \implies10x - 6 = ([\frac{1}{ \cancel2} \times \cancel 6 \: x] - [\frac{1}{ \cancel2} \times \cancel2]) \\ \\ \implies 10x - 6 = 3x - 1 \\ \\ \fbox{Bringing (3x )to left side whereas( - 6 )in right side} \\ \\ \implies10x - 3x = - 1 + 6 \\ \\ \implies7x = 5 \\ \\ \therefore x = \frac{5}{7}$

The Solution is = $\frac{5}{7}$

$\text\red{One Solution set is possible.}$

I believe the answer would be 70 but make sure just in case.
