Answer:

X = 1 which means Y = -1

Step-by-step explanation:

2x - y = 3                    

y = -x                              

Sub for y

2x + x = 3

Add the x's

3x = 3

Divided by 3

x = 1

Answer:

These are simultaneous equations.They have to be solved like this:

2x-y=3 -y=3-2x 2x-3= -x

y= -x y= -(3-2x) 3x= 3

y=2x-3 x=1

Step-by-step explanation:

The value of x equals to 1

Fran deposited 4869 into a savings account that pays simple annual interest rate of 3.25% how much interest will she earn after
Whitepunk [10]

Answer:

$395.61

Step-by-step explanation:

The formula for simple interest is:

i=Prt

Where

i is the interest amount

P is the principal amount

r is the rate of interest per time period

t is the time period

Here,

P = 4869

we want to find after 30 months, that converted to years is:

30/12 = 2.5 years

t = 2.5

The annual rate is 3.25% = 0.0325

Now, substituting, we find our answer:

i=Prt\\i=(4869)(0.0325)(2.5)\\i=395.61

The interest earned is <u>$395.61</u>

Which is the height of the triangle?<br> ( PIC IS PROVIDE PLS HELP ME)
zysi [14]
<h3>Answer: 80 meters</h3>

This is an isosceles triangle. The dashed line is the height which is perpendicular to the base 120. The height is always perpendicular to the base. The dashed line cuts the base into two equal pieces (this only works for isosceles triangles when you cut at the vertex like this).

So we have two smaller triangles each with a base of 60 and a height of x. Focus on one of the right triangles and use the pythagorean theorem to solve for x.

a^2 + b^2 = c^2

x^2 + (60)^2 = (100)^2

x^2 + 3600 = 10000

x^2 = 10000 - 3600

x^2 = 6400

x = sqrt(6400)

x = 80

Each smaller right triangle has side lengths of 60, 80, 100

Note the ratio 60:80:100 reduces to 3:4:5. A 3-4-5 right triangle is a very common pythagorean primitive.
