What is the solution to the system of equations?
Sever21 [200]

Answer:

(-2,\frac{5}{3})

Step-by-step explanation:

Given:

The system of equations given are:

y=\frac{2}{3}x+3\\x=-2

Plug in x=-2 in the first equation and solve for y.

y=\frac{2}{3}(-2)+3\\y=\frac{-4}{3}+3\\y=\frac{-4}{3}+\frac{9}{3}\\y=\frac{-4+9}{3}=\frac{5}{3}

Therefore, the solution is (x,y)=(-2,\frac{5}{3})

PLEASE MATH HELP ALGEBRA 1
S_A_V [24]
F(x) shows number of bees and g(x) shows number of flowers
f(x)=1500*(0.88)^n
g(x)=800-25n
n shows month
B)n=6
1500*(0.88)^6=696
800-25*6=800-150=650
c)it's hard to say because you should find n in this equation
1500*(0.88)^n=800-25n
but it seem n is between 6 and 7

Write x as a logarithm in the following: 10^x=7
pochemuha

Answer:

x = log 7

Step-by-step explanation:

10^x=7

Take the log base 10 on each side

log10 (10^x)=log10 (7)

We dont need to write the 10, it is implied

log(10^x)=log (7)

The exponent  goes out front since log a^b = b log a

x log 10 = log 7

log 10 = 1 since the base is 10 log10(10) =1

x = log 7

3 10 in . = 7 8 mi . what is the unit rate
Sav [38]

Answer: (3/10) in = (7/8) mi

1 in = (7/8) mi ÷ (3/10)

      = 7/8 * (10/3) = 70/24

1 in = (70/24) mi

It means every 1 inch on the map drawing represents (70/24) miles ≈ 2.917 miles in reality.  

Hope this helps :)
