It's 30.48 cause each inch is 2.54 centimeters and times it by 12 =30.48

what is the value of y in the solution to the following system of equations? (5 points) 2x y = −4 5x 3y = −6

TiliK225 [7]

2x+y=-4
5x+3y=-6

multiply first equaton by -5 and second by 2 then add them

-10x-5y=20
<u>10x+6y=-12 +</u>
0x+1y=8

y=8

the y value is 8

Answer:

$108.19

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 3.6%/100 = 0.036 per year.

Solving our equation:

P = 119.88 / ( 1 + (0.036 × 3)) = 108.19494584838

P = $108.19

The principal investment required to get a total amount, principal plus interest, of $119.88 from simple interest at a rate of 3.6% per year for 3 years is $108.19.

Hope this helps!

a new line is drawn through the point (-3,6) and perpendicular to the line with x-intercept (3,0) and y intercept (0,3) . what i

Klio2033 [76]

Answer:

The equation of the new line is $y=x+9$ or $y-6=(x+3)$

Step-by-step explanation:

step 1

Find out the slope of the line with x-intercept (3,0) and y intercept (0,3)

The formula to calculate the slope between two points is equal to

$m=\frac{y2-y1}{x2-x1}$

substitute the values

$m=\frac{3-0}{0-3}=-1$

step 2

Find the slope of the new line perpendicular to the given line

we know that

If two lines are perpendicular,then their slopes are opposite reciprocal (the product of their slopes is equal to -1)

$m_1*m_2=-1$

we have

$m_1=-1$ ----> slope of the given line

$m_2=1$ ---> slope of the new line

step 3

Find the equation of the new line in point slope form

$y-y_1=m(x-x_1)$

we have

$m=1$

$(x_1,y_1)=(-3,6)$

substitute

$y-6=(1)(x+3)$

$y-6=(x+3)$ ----> equation in point slope form

Convert to slope intercept form

$y=mx+b$

isolate the variable y

$y=x+3+6$

$y=x+9$
