Write the equation of the line that passes through (-3,5) and (2, 10) in slope-intercept form.

cupoosta [38]

Answer:

$y=x+8$

Step-by-step explanation:

Slope of straight line can be calculated as

$m=\frac{y_2-y_1}{x_2-x_1}$

Here $(x_1, y_1)=(-3, 5) \ and \ (x_2, y_2) = (2, 10)$

$m =\frac{10-5}{2-(-3)}\\m=1$

Equation of straight line in slope intercept form is

$y-y_1=m(x-x_1)\\y-5=(x+3)$

$y=x+8$

Let $a_1$, $a_2$, . . . , $a_{10}$ be an arithmetic sequence. If $a_1 + a_3 + a_5 + a_7 + a_9 = 17$ and $a_2 + a_4 + a_6 + a_8 +

So

a be first term and d be common difference

a+a+2d+a+4d+a+6d+a+9d=17
5a+21d=17--(1)

And

a+d+a+3d+a+5d+a+7d+a+9d=15
5a+25d=15--(2)

Eq(1)-Eq(2)

-4d=-2
d=1/2

Put in second one

5a+25d=15
a+5d=3
a+5/2=15
a=15-5/2
a=25/2

PLEASE HELP ME!

schepotkina [342]

Answer:

76.8

Step-by-step explanation:

Using the proportion

$\frac{120}{100}$ → Percent is out of 100

$\frac{120}{100}$ = $\frac{n}{64}$ ( cross- multiply )

100n = 7680 ( divide both sides by 100 )

n = 76.8

How do I solve for x?

notka56 [123]

Solving:
$\frac{3+4x}{2} + \frac{5-x}{3} = \frac{29}{6}$
Make the Least Common Multiple (2,3,6)
$2,3,6\:|2$
$1,3,3\:|3$
$1,1,1\:|\underline{2*3=6}$

<span>Replace denominators and resolve:
</span> $\frac{3+4x}{2} + \frac{5-x}{3} = \frac{29}{6}$
$\frac{3(3+4x)}{6} + \frac{2(5-x)}{6} = \frac{29}{6}$
Cancel the dominators
$\frac{3(3+4x)}{\diagup\!\!\!\!6} + \frac{2(5-x)}{\diagup\!\!\!\!6} = \frac{29}{\diagup\!\!\!\!6}$
$3(3+4x) + 2(5-x) = 29$
$9 + 12x + 10 - 2x = 29$
$12x - 2x = 29 - 9 - 10$
$10x = 20 - 10$
$10x = 10$
$x = \frac{10}{10}$
$\boxed{\boxed{x = 1}}\end{array}}\qquad\quad\checkmark$
