What is the value of x for the equation 4x – 2y = 6 if y= -3?

Mathematics

Serhud [2]3 years ago
5 0

Answer:

x = 0

Step-by-step explanation:

Let's divid both sides of the equation by 2 first, so we don't have as much work to do in the next step:

4x-2y=6\\2x-y=3

Substituting -3 for y:

2x-(-3)=3\\2x+3=3\\2x=0\\x=0

A square measures 6r centimeters on each side. Which monomial represents the area of the square?
OleMash [197]

Answer:

Option 4

Step-by-step explanation:

So we know that the area of a square is found by s^2. This means that we can just look for (6r)^2, since 6r is our side length! Let's see...We know that (6r)^2 is equal to 6^2 times r^2 because of the distributive property of exponents. Therefore, option 4 is our right answer. 36 is 6^2 and r^2 is r^2.

Jerome bought screen for 59 cents per sq ft. how much did 12 sq ft cost
Gre4nikov [31]

Answer:

$7.08

Step-by-step explanation:

59 cents = 1 sq ft

? = 12 sq ft

To get from the 1 to the 12 we multiply by 12, so we must do the same to the 59 cents.

0.59 * 12 = 7.08

Therefore, the cost of 12 sq ft is $7.08.

Records indicate that x years after 2008, the average property tax on a three bedroom home in a certain community was T(x) =20x^
dem82 [27]

Answer:

a) 40 dollars

b) 480 dollars

Step-by-step explanation:

Given the average property tax on a three bedroom home in a certain community modelled by the equation T(x) =20x²+40x+600, the rate at which the property tax is increasing with respect to time in 2008 can be derived by solving for the function T'(x) at x=0

T'(x) = 2(20)x¹ + 40x° + 0

T'(x) = 40x+40

At x = 0,

T'(0) = 40(0)+40

T'(0) = 40

Hence the property tax was increasing at a rate of 40dollars with respect to the initial year (2008).

b) There are 4 years between 2008 and 2012. To know how much that the tax change between the years 2008 and 2012, we will find T(4) - T(0)

Given T(x) =20x²+40x+600

T(4) =20(4)²+40(4)+600

T(4) = 320+160+600

T(4) = 1080 dollars

Also T(0) =20(0)²+40(0)+600

T(0) = 0+0+600

T(0)= 600 dollars

T(4) - T(0) = 1080 - 600

T(4) - T(0) = 480 dollars

Hence, the tax has changed by $480 between 2008 and 2012

1/8 is it greater or lesser than 1/4
geniusboy [140]
1/8 is less than 1/4 because when it comes to solving this kind of problem (with fractions) if the numerators(the top numbers) are the same, the fraction with the <span>higher </span>denominator , is going to be less. Hope this helps! :)
Example: 1/2 is greater than 1/4.
