Solve the following systems of equations without graphing
5x + 10y = 30
-5x +15y = 20

Answers

Answer:

(2, 2)

Step-by-step explanation:

In this case, elimination would be the most efficient means of solving.

Simply, add the two equations, and you will be left with only one variable to solve for. (In this case y) You are then able to take your solution and plug it into an equation and solve for x, therefore giving you their intercept.\

5x + 10y = 30

-5x + 15y = 20

(x's cancel) 25y = 50

25y = 50

y = 2

5x + 10(2) = 30

5x + 20 = 30

5x = 10

x = 2

The solution to this equation is (2, 2)

What is the measure of angle TMS? Pls explain your answer and I will mark brainliest!

Answers

Answer:

38 degrees

Step-by-step explanation:

If the line is tangent that means it forms a 90 degree angle. The angle measure of the inside of a triangle is equal to 180 degrees. If you add 52 and 90 you get 142. Subtract this amount from 180 and you will get the measure of m TMS

#1. Step one) we set find what we can multiply by 5 to get 20, so we divide 20 by 5.
20/5 = 4
Step two) we multiply the bottom denominator (8) by 4
8x4=32
Step three) leave the top numerator the same (20) and replace (d) with 32
Answer : 20/32

Find the 13th term of the geometric sequence 3, -15, 75, ...

Answers

the terms of geometric sequence are 3, -15, 75

given,

1st term (a) = 3

second term (t2)=-15

common ratio (r) = t2/t1

=-15/3

=-5

then

t13= ar^n-1

=3×(-5)^13-1

=3×244140625

=732421875.

The [tex]13^{th}[/tex] term of the geometric sequence is - 732421875.

A geometric sequence is given ; 3 , -15 , 75....

We have to find the [tex]13^{th}[/tex] term of the geometric sequence.

What is the formula for calculation of nth term of geometric Sequence ?

The formula for calculation of nth term of geometric progression is [tex]a_{n}[/tex] = [tex]a_{1}[/tex] × [tex](r)^{n-1}[/tex] where r is the common ratio of geometric sequence.

Given geometric sequence is 3 , -15 , 75....

and

Common ratio is r.

i.e., r = -15 ÷ 3 = -5

∵ [tex]n^{th}[/tex] term of a geometric sequence is given by ;

[tex]a_{n}[/tex] = [tex]a_{1}[/tex] × [tex](r)^{n-1}[/tex]

where [tex]a_{1}[/tex] is the first term.

So,

[tex]13^{th}[/tex] term of the geometric sequence will be ;

[tex]a_{13}[/tex] = 3 × [tex](-5)^{12}[/tex]

[tex]a_{13}[/tex] = - 732421875

Thus , the [tex]13^{th}[/tex] term of the geometric sequence is - 732421875.

B)ZR and ZW are not corresponding angles.

I think its D but im not completely sure. Good luck:)

Step-by-step explanation:

Complete the triangle. Find all missing sides and angles. Round to the nearest tenth. Triangle DEF; DE=23 and FE=25

DF=?
Angle F=?
Angle E=?

help pls!!

Answers

Answer:

DF= 9.8

Angle F= 42.6 degrees

Angle E= 23.1 degrees

Step-by-step explanation:

so for the sides we can use the pythagorean theorem

23^2+b^2=25^2

23 squared is 529 and

25 squared is 625

529+b^2=625

subtract 529 from both sides

b^2=96

the square root of 96 is ~9.8

b=9.8

To find the angles you use sin, cos, or tan. Now that we know all three sides it doesn't matter which one you use so... pick your favorite.

sinf=23/25

f= ~66.9 degrees

tane= 23/25

e= ~23.1
