Answer:

The solution of the system of equations is the point (-3,-4)

Step-by-step explanation:

we have

y=x-1 -----> equation A

y=-\frac{4}{3}x-8 -----> equation B

we know that

The solution of the system of equations, is the intersection point both graphs

Using a graphing tool

The intersection point is (-3,-4)

see the attached figure

therefore

The solution of the system of equations is the point (-3,-4)

A new one-year membership at RecPlex costs $160. A registration fee of $28 is paid up front, and the rest is paid monthly. How m
anzhelika [568]

Answer:

The first month new members have to pay 188 dollars for the membership.

The equation is 160x+28=y

x stands for the number of months and y stands for the total cost.

For the first month (membership starts) the total cost is 188$. For the second month the total money paid would be 348$. For the third month the total money paid would be 508$. And so on you can use the equation to solve for more months. Just substitute x for the number of months you are solving for.

when you are dividing two decimals how can you check whether you have divided the decimals correctly?
Mice21 [21]

Dividing two decimals means that we need to make the following math operation:

\frac{p}{q} \\ \\ where \ p \ and \ q \ are \ two \ decimals

According to the following definition:

If \ p \ and \ d \ are \ two \ real \ numbers \ (two \ decimals) \ it \ is \ true \ that:\\ \\  p=d\times q+r \\ \\ where:\\ \\ p:Dividend \\ d:Divisor \\q:Quotient \\ r:Reminder


We can prove that our result is correct by multiplying the divisor by the quotient plus the reminder and verifying that this result matches the dividend. Also, we can use a calculator to prove that.

Factor this trinomial. Your answer should consist of two binomials.
Sergeu [11.5K]
Y² + 8y - 33 :

Break  the expression  into groups for formula ax²+ bx+c :

= (y²- 3y) + (11y - 33 )

Factor y from y² - 3y =>  y (y - 3)

Factor out 11 from  11 y - 33 => 11 (y - 3)

= y ( y- 3 ) + 11 ( y - 3 )

Factor  out common  term (y - 3 ) :

= ( y - 3 ) ( y + 11 )

hope this helps!

Hey can you please help? I am struggling a lot don’t know how to solve this
Ket [755]

Answer:

64.8

Step-by-step explanation:

Pythagoreon Theroem

a^2 + b^2 = c^2  in  this situation it would actually be the opposite, seeing where the "x" is (on a leg) c^2 - b^2 = a^2. First  take the square of 67 and 17

67 squared is 4489 and 17 squared is 289 then  subtract both results

4489-289 = 4200 take the square root of this number

64.8074  (Round to the tenths 64.8)
