Answer: y=-1 and x=2

Step-by-step explanation:

-9x+8y=-26

-9x-6y=-12

Subtract

14y = -14

Divide by 14

Y=-1

Substitute y=-1 into the equation

-9x-6(-1)=-12

-9x+6=-12

Subtract 6

-9x=-18

Divide by -9

X=2

-1/2+ 7/8- 1/10 Hint: rational numbers

ki77a [65]

After solving $-\frac{1}{2}+\frac{7}{8}-\frac{1}{10}\\$ we get $\frac{11}{40}$

Step-by-step explanation:

We need to solve the following expression:

$-\frac{1}{2}+\frac{7}{8}-\frac{1}{10}\\$

Solving the above expression we need to find the LCM of denominators: 2,8,10

The LCM of 2,8,10 is 40

$-\frac{1}{2}+\frac{7}{8}-\frac{1}{10}\\=\frac{-1*20+7*5-1*4}{40}\\=\frac{-20+35-4}{40}\\=\frac{11}{40}$

So, after solving $-\frac{1}{2}+\frac{7}{8}-\frac{1}{10}\\$ we get $\frac{11}{40}$

What is the initial value in the exponential equation below? y = = 4000(1.05)*

Svet_ta [14]

Answer:

$y = 4000$ (when x = 0)

Step-by-step explanation:

The initial value of the exponential equation is:

$y = 4000\cdot (1.05)^{0}$

$y = 4000\cdot 1$

$y = 4000$
