Does the point (–1, 5) satisfy the equation y = 7x?

Mathematics
1 answer:
damaskus [11]3 years ago
5 0

Answer:

no

Step-by-step explanation:

Substitute the x- coordinate into the equation and if the result is equal to the y- coordinate then it satisfies the equation, that is

y = 7(- 1) = - 7 ≠ 5

Then (- 1, 5 ) is not a solution to the equation

The area of a rectangular computer screen is 4x^2+20x+16. The width of the screen is 2x+8. What is the length of the screen?
Aleksandr-060686 [28]
So the area of a rectangle is Length x Width. 
A = (L)(W)
Substitute the information given:
4x^2 + 20x + 16 = (L)(2x+8)
Isolate L by dividing 2x+8:
(4x^2 + 20x +16)/ (2x + 8) = L
If you divide: 
L = 2x + 2.

Helpppp!?! <br> - 8 = - ( x + 4
Vlad1618 [11]
-8=-(x+4)
remember the invisible 1
-8=-1(x+4)
distribute using distributeiv porpety
a(b+c)=ab+ac
-1(x+4)=-x-4

-8=-x-4
add 4 to both sides
-4=-x
mutily both sides by -1
4=x

Shota invests $2000 in a certificate of deposit that earns 2% in interest each year.Write a function that gives the total v(t) i
brilliants [131]

Answer:

The correct answer is v(t) = (principal × time × 0.02) if calculated simply and v(t) = Principal × ( 1.02) ^ {time} where v(t) is the interest after t years .

Step-by-step explanation:

Principal amount invested by Shota is $2000.

Interest is earned at 2% per year.

Time for which the principal is invested is t years.

Therefore let the total interest be v(t) dollars in t years.

Case 1: Simple Interest.

v(t) = (principal × time × \frac{r}{100} ) = (2000 × t × 0.02) = 40t

Case 2: Compound Interest.

v(t) = Principal × ( 1+ \frac{r}{100}) ^ {t} - Principal =  2000 × ( 1.02) ^ {t} - 2000.
