What is the solution to the linear system of equations?y = 3x + 1
y = –x + 5

A.
(2, 7)


B.
(0, 5)


C.
(1, 4)


D.
The system has no solution.

Answers

Answer 1
Answer: Hello,

Answer C

y=3x+1
y=-x+5
==>3x+1=-x+5
==>4x=4
==>x=1 and y=-x+5=-1+5=4

(1,4) is the solution.

Answers

Check the picture below.

\bf \textit{volume of a pyramid}\n\n V=\cfrac{1}{3}Bh~~ \begin{cases} B=&area~of\n &its~base\n h=&height\n \cline{1-2} B=&\stackrel{9* 9}{81}\n h=&10 \end{cases}\implies V=\cfrac{1}{3}(81)(10)\implies V=270

the area of a triangle is 124 square units. what would it's new area be if its base was half as long and its height was three times as long?

Answers

To solve this problem you must apply the proccedure shown below:

 1. You have that the formula for calculate the area of a triangle is:

 A=bh/2

 Where A is the area of the triangle, b is the base of the triangle and h is the height of the triangle.

 bh/2=124
 bh=124x2
 bh=248

 2. The problem asks for the new area of the triangle if its base was half as long and its height was three times as long. Then, you have:

 Base=b/2
 Height=3h

 3. Therefore, when you substitute this into the formula for calculate the area of a triangle, you obtain:

 A'=bh/2

 (A' is the new area)

 A'=(b/2)(3)/2
 A'=3bh/4

 4. When you substitute bh=248 into A'=3bh/4, you obtain:

 A'=186 units²

 The answer is: 186 units²

The sides of a triangle are in the ratio 3 : 4 : 5. What is the length of each side if the perimeter of the triangle is 90 cm?

Answers

what we can do is set up an algebraic equation. 

our variable can me L for Length

3L+4L+5L=90

now all we have to do is solve

12L=90
----   ----
12      12

L=7.5

now multiple each number in the ratio by 7.5 to find out how long each side is

3 times 7.5 is 22.5
4 times 7.5 is 30
5 times 7.5 is 37.5

the side lengths are 22.5, 30, and 37.5
