Solve the following pair of equations by elimination method: x+y=4, 2x+y=3​
allsm [11]

Answer:

x = 1

y = 5

Step-by-step explanation:

x + y = 4 __ (1)

2x + y = 3 __ (2)

equation (1) x 2, (2) x 1

2x + 2y = 8

2x + y = 3

0  + y = 5

y= 5 (ANS)

x + y = 4

x + 5 = 4

x = 5 - 4

x = 1 (ANS)

I HOPE MY ANSWER IS CORRECT IF NOT I APOLOGIZE.

Answer:

- Right Angle Triangle – A Right triangle is a triangle in which one angle is a right angle (that is, a 90-degree angle). The relation between the sides and angles of a right triangle is the basis for trigonometry (opposite, hypotenuse, adjacent).

- Obtuse Triangle – An obtuse triangle is a triangle with one obtuse angle (greater than 90°) and two acute angles.

- Acute Triangle – An acute triangle is a triangle with three acute angles (less than 90°).  

12 - Right Angle Triangle

13 - Obtuse Triangle

14 - Acute Triangle

15 - Acute Triangle

16 - Right Angle Triangle

17 - Obtuse Triangle

U guys are crazy awesome 7.04 Q13​
finlep [7]

Answer:

5088

Step-by-step explanation:

The initial value  of the car is $19340

The rate of decrease is 12.5%

The value of the car after 10 years is given by

A=P(1-r\%)^n

Substitute the values to get;

A=19340(1-12.5\%)^{10}

\Rightarrow A=19340(1-12.5\%)^{10}

\Rightarrow A=19340(1-0.125)^{10}

\Rightarrow A=5087.88

To the nearest dollar we have $5088

The correct answer is choice C

Write in slope-intercept form an equation of the line that passes through the given points.
Kipish [7]

Answer:

y = 2x

Step-by-step explanation:

Let's first find the slope:

m = (y₂ - y₁)/(x₂ - x₁)

m = (6 - 4)/(3 - 2) = 2/1 = 2

Now let's use point-slope form:

y - y₁ = m(x - x₁)

(For x₁ and y₁, you can use either (2,4) or (3,6), but I'm gonna use (2,4))

y - 4 = 2(x - 2)

y - 4 = 2x - 4

y = 2x

That's your answer.

Hope this helps, and hope you learned something!
