Y=1/2x-5 Write it in a standard form

1 answer:

3 0

We know that

To write a linear equation in standard form, move each variable term to the left side of the equation and simplify.Ax+By=C

so
Y=1/2x-5--------> (1/2)x-y=5
where
A=1/2
B=-1
C=5

the answer is
 (1/2)x-y=5

Find the compound interest on Rs. 2000 for one year at the rate of '20%' per annum. If theinterest compounded quarterly.

trasher [3.6K]

Given:

Principal = Rs. 2000

Rate of interest = 20% p.a. compounded quarterly.

Time = 1 year

To find:

The compound interest.

Solution:

Formula for amount:

$A=P\left (1+\dfrac{r}{n}\right)^{nt}$

where,

P = Principal

r = Rate of interest

t= Time

n = number of times interest compounded in an year.

Putting P=2000, r=0.2, n=4 and t=1, we get

$A=2000\left (1+\dfrac{0.2}{4}\right)^{4(1)}$

$A=2000\left (1.05\right)^{4}$

$A=2000\left (1.21550625\right)$

$A=2431.0125$

Now, the compound interest is

$C.I.=A-P$

$C.I.=2431.0125-2000$

$C.I.=431.0125$

Therefore, the compound interest is Rs 431.0125.

3 3/4 / 2/5 = what? I'm struggling

Soloha48 [4]

Lets convert 3 3/4 into improper fraction first.

$3\frac{3}{4} = \frac{3 \times 4 + 3}{4} \\ = \frac{15}{4}$

$\frac{3\frac{3}{4} }{ \frac{2}{5} } \\ = \frac{15}{4} \div \frac{2}{5} \\ = \frac{15}{4} \times \frac{5}{2} \\ = \frac{75}{6} \\ = \frac{25}{2} \: or12 \frac{1}{2} or \: 12.5$

Which equation in slope-intercept form represents a line that is parallel to y=−4x−5 and passes through the point (0,0)?

Contact [7]

Answer:

Step-by-step explanation:

The line is negative and it was shifted down 5 units meaning it goes through -5,0. It needs to move up five so y=-4x-5+5= y=-4x

‘| |’ means modulus.
It’s turns the internal value positive.
We get a negative answer while finding the area of a triangle because there points in the quadrant other than the 1st quandrant i.e where all values are positive
Area of a triangle can never be negative, so we use modulus
