Answer:

The equation is y=2x + 2

Step-by-step explanation:

4x+2y=7

2y=-4x+7

y=-2x+7/2

Hence, the gradient =-2

Note that: parallel lines share the same gradient

sub m(gradient)=-2 and the point (1,0) into y=mx+c

0=-2(1)+c

c=2

Therefore, the equation in the form of y=mx+c is y=-2x+2

Tori examined the pattern of exponents in the table.

gregori [183]

Answer:

The value of b = 1/36

As exponent decreases, each previous value is divided by 6

If the table was extended, the value of 6^-3 would be 1/216

Step-by-step explanation:

Given in the question a table containing power of 6

We will use negative rule of exponent to write the equivalent of negative power of 6

b^{-n}= 1 / b^{n}

we know that

$6^{1}=6$

$6^{-1} =\frac{1}{6^{1} }$

= 1/6

and

$6^{2} = 36$

So,

$6^{-2} = \frac{1}{6^{2} }$

$\frac{1}{36}$

Consider a home mortgage of $250,000 at a fixed APR of 4.5% for 30 years. a. Calculate the monthly payment. b. Determine the t

lianna [129]

Answer:

a. payment: $1266.71

b. total paid: $456, 015.60

c. fraction to principal: 54.8%; fraction to interest: 45.2%

Step-by-step explanation:

The amortization formula tells you the monthly payment is ...

A = P(r/12)/(1 -(1 +r/12)^(-12t))

Payment on principal P at annual rate r for t years.

A = $250,000(0.045/12)/(1 -(1 +0.045/12)^(-12·30)) ≈ $1266.71

The monthly payment is $1266.71.

360 monthly payments of $1266.71 will have a total value of ...

360 × $1266.71 = $456,015.60 . . . . total amount paid

Of course, $250,000 is paid on the principal. That percentage is ...

$250,000/$456,015.60 × 100% ≈ 54.8% . . . to principal

The remaining fraction is paid for interest:

100% -54.8% = 45.2% . . . to interest
