Please answer the question below. please provide an explanation as well. thanks!
Elena-2011 [213]

Answer:

14

Step-by-step explanation:

Since S is the midpoint of RT, then RS = ST

RS = RT - ST = (3x + 7) - (x + 7) = 3x + 7 - x - 7 = 2x

so we get that RS = 2x

but since RS = ST, and RS=2x & ST=x+7

then 2x = x + 7

       2x-x = 7

        x = 7

ST = x+7 = 7+7 = 14

P.S. Hope it makes sense. If you have any questions, feel free to ask them in the comments senction. I'll be happy to help. Have a wonderful day!

What is the slope if the line through the points 2/3, 4/7 and 2/3, 11/7
Umnica [9.8K]

The fromula of a slope:

m=\dfrac{y_2-y_1}{x_2-x_1}

We have the points \left(\dfrac{2}{3},\ \dfrac{4}{7}\right) and \left(\dfrac{2}{3},\ \dfrac{11}{7}\right)

Substitute:

m=\dfrac{\frac{11}{7}-\frac{4}{7}}{\frac{2}{3}-\frac{2}{3}}=\dfrac{\frac{7}{7}}{0}\ !!!!

<h3>Answer: slope is undefined.</h3><h3 />

It's a vertical line: x=\dfrac{2}{3}

The population of a town was 10,000 in 2018. Each year the town's population grows by 23%. Let x=0 be the year 2018. Create the
Naily [24]

Answer:

 f(x)=10000(1.23)^x

Step-by-step explanation:

We are going to apply algebra to solve for the exponential growth

we know that the expression for the exponential formula is

y = ab^x.

where

a = the amount before measuring growth or decay

= 10,000

r = growth or decay rate = 23%= 0.23

x = number of time intervals that have passed

since this problem is on the growth we are going to replace "b" with (1+r), likewise for decay (1-r)

hence the formula becomes

y = a(1+r)^x.

f(x)=10000(1+0.23)^x \\\\f(x)=10000(1.23)^x

The expression that will give the population value is

f(x)=10000(1.23)^x
