Answer:

x = -4

y = 1

(-4,1)

Step-by-step explanation:

x = -11 +7y

5x + 2y = -18

This is a Substitution problem, so you put x = -11+7y into 5x+2y = -18

5(-11 +7y)+2y = -18

5(-11) = -55

5(+7y) = 35y

-55+35y+2y = -18

Now you add 35y and 2y which gives you 37y

-55+37y = -18

Now you add +55 from -55 and -18

37y = 37

You divide each side by 37 so that y = 1

Now you plug y(1) into the equation x = -11+7y

x = -11+7(1)

-11+7 = -4

x = -4

Answer:

i think 20 is above 12 and 17 under 30 and 36 is on top of 20 the rule is .50(x) +2

Answer:

Step-by-step explanation:

c = 0.5t + 2

12 = 0.5t + 2 ⇒ 0.5t = 10 ⇒ t = 20

c = 0.5(30)  + 2 ⇒ c = 17

20 = 0.5t + 2 ⇒ 0.5t = 18 ⇒ t = 36

Answer:

10 percent

Step-by-step explanation:

- Before 1997, people with a minimum FBGL of 140mg/dl were diagnosed as diabetic

- After 1997, people with a minimum FBGL of 126mg/dl were diagnosed as diabetic

- What is the proportion of people who were not considered diabetic before 1997 but are now considered diabetic (after 1997)?

140 - 126 = 14

In percentage, this proportion is = 14/140 × 100

= 10%

Hence, 10% of the people who were not considered diabetic before 1997 are now or will now be considered diabetic.

The value that is a solution of the rational equation that must be discarded because of the context is (b) x = -10

The equation is given as:

[tex]\frac 1x + \frac{1}{x + 18} = \frac{1}{40}[/tex]

Take the LCM

[tex]\frac{x + 18 + x}{x(x + 18)} = \frac{1}{40}[/tex]

This gives

[tex]\frac{2x + 18}{x(x + 18)} = \frac{1}{40}[/tex]

Cross multiply

[tex]40(2x + 18) =x(x + 18)[/tex]

Expand

[tex]80x + 720 =x^2 + 18x[/tex]

Collect like terms

[tex]x^2 + 18x - 80x -720 = 0[/tex]

[tex]x^2 - 62x -720 = 0[/tex]

Using a graphing calculator, we have:

[tex]x = 72\ or\ x =-10[/tex]

The value of x cannot be negative, because of the context.

So, the value that is a solution of the rational equation that must be discarded because of the context is (b) x = -10

Step-by-step explanation:

Answer:

The value of x is 5.

Step-by-step explanation:

In a square, all sides are equal so you can compare the expressions to solve x :

What's HJ? Never heard of it

We are given the equation:

DA - 2qA = B³

Taking 'A' common on the LHS

A(D - 2q) = B³

Dividing both sides by (D - 2q)

A = B³ / (D - 2q)

Answer:45.167

Step-by-step explanation:

So you're using the Pythagorean theorem which is a^2 + b^2 = c^2... so if you don't have b you can manipulate the equation. That equation is c^2 - a^2= b^2, so you square 47 which is 2209 and then square 13 which is 169... you do 2209-169 and that equals 2040, then you do the square root of that which is 45.166359 that can be simplified to 45 or two decimal points 45.167.

Answer:

B) -30

Step-by-step explanation:

multiply -20 by 3/2 to solve for x

Step-by-step explanation:

Given [tex]g'(x) = g^{-2}, x> 0\ g(1) = 0 \ and \ g(2) = 0[/tex]

To get g(x), we will have to integrate g'(x)

[tex]g(x) = \int\limits {x^{-2}} \, dx\\ g(x) = \frac{x^{-2+1}}{-2+1} + C\\ g(x) = -x^{-1} + C\\g(x) = -x^{-1} + C\\[/tex]

If g(1) = 0, this means at x = 1, g(x) = 0

0 = -1⁻¹ + C

C= 1

Substitute C = 1 into the function

g(x) = -x⁻¹ + 1

If g(2) = 0, this means at x = 2, g(x) = 0

0 = -2⁻¹ + C

C= 2⁻¹

C =  1/2

Substitute C = 2 into the function

g(x) = -x⁻¹ + 1/2
