If rx - st = r , which expression represents x

Mathematics
1 answer:
expeople1 [14]2 years ago
5 0
Your goal is to have x by itself
Send st to other side
rx= r+st

Divide by r so x stays alone

X=(r+st)/r

Which is also equal to

X=r/r+st/r
X= 1+st/r

Find the measure of angle A.<br> A<br> 9x+6<br> 4x + 6<br> m/A=
Likurg_2 [28]

Answer:

angle A=30°

Step-by-step explanation:

9x + 6 + 4x + 6 + 90 = 180 \\ 13x + 102 = 180 \\ 13x = 180 - 102 \\ 13x =  78 \\  \frac{13x}{ 13} =  \frac{ 78}{13} \\ x = 6 \\ 4x + 6 = a \\ 4(6) + 6 = a \\ 24 + 6 = a \\ 30 = a

When given points (1,1) and (2,2), what is the slope ?
scoray [572]

Answer:

m=1

Step-by-step explanation:

Slope can be calculated using following formula

m=\frac{y_2-y_1}{x_2-x_1}  ----------- (1)

<u>Here</u>

(x_1, y_1)=(1, 1) \ \ and \ \ (x_2, y_2) = (2, 2)

Substitute values in equation (1)

m=\frac{2-1}{2-1}

m=1

What is the sum of the infinite geometric series?<br><br> mc010-1.jpg
ra1l [238]
You haven't provided the series, therefore, I can only help with the concept.

<u><em>For an infinite geometric series, we have two possibilities for the common ratio (r):</em></u>
for r > 1, the terms in the series will keep increasing infinitely and the only possible logic summation of the series would be infinity
for r < 1, the terms will decrease, therefore, we can formulate a rule to get the sum of the infinite series

<u><em>In an infinite series with r < 1, the summation can be found using the following rule:</em></u>
sum = \frac{a_{1} }{1-r}
where:
a₁ is the first term in the series
r is the common ratio

<u>Example:</u>
For the series:
2 , 1, 0.5 , 0.25 , ....
we have:
a₁ = 2
r = 0.5
Therefre:
sum = \frac{2}{1-0.5} = 4

Hope this helps :)

For f(x) = x2 and g(x) = (x − 5)2, in which direction and by how many units should f(x) be shifted to obtain g(x)? (5 points) Up
IgorC [24]

Answer:

5 units to the right.

Step-by-step explanation:

The x in f(x) is replaced by x - 5 to give g(x).

The - 5 will shift f(x) 5 units to the right.
