Y = 4x – 10

Mathematics
2 answers:
antoniya [11.8K]3 years ago
4 0

Answer:

(3,2)

Step-by-step explanation:

y = 4x – 10...(1) y = 2...(2) You have y=2 here, substitute it in equation (1),

y = 4x – 10 2 = 4x – 10

Add both sides by 10 12=4x

Divide both sides by 4 x=3

We have x=3, and y=2. ==> (x,y) = (3,2)

Answer:

(3,2)

Step-by-step explanation:

y = 4x – 10

y = 2

Substitute the second equation into the first

2 = 4x-10

Add 10 to each side

2+10 = 4x-10+10

12 = 4x

Divide each side by 4

12/4 =4x/4

3 = x

The solution is

(3,2)

Greg invested $6000 in a bond with a yearly interest of 4%. His total interest on his investment was $1200. What was the length
kow [346]

Answer:

5 years

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 4%/100 = 0.04 per year,

then, solving our equation

t = 1200 / ( 6000 × 0.04 ) = 5

t = 5 years

The time required to

accumulate simple interest of $ 1,200.00

from a principal of $ 6,000.00

at an interest rate of 4% per year

is 5 years.

What is the measure of an angle if it is 660 less than 6 times its own supplement
otez555 [7]

Answer:

60

Step-by-step explanation:

Since this angle is unknown, let's just represent it with the variable "x". So the supplement angle of "x" is essentially, the value of the angle that we need to add to "x" to get 180. In other words let's just say that the supplement angle is "y". This means that: x+y=180. If we subtract x from both sides we can represent "y" or the supplement angle as: (180-x).

Since it's 660 less than 6 times it's own supplement let's first multiply the supplement by 6

6(180-x) = 1,080-6x

Now let's subtract 660 from it, since it's 660 less

(1,080 - 6x) - (660) = 420 - 6x

This value should be equal to the angle, which is represented as "x". So let's set it equal to x

420-6x=x

Add 6x to both sides

420=7x

Divide both sides by 7

60 = x
