Answer:

B. a. Given; b. Substitution Property; c. Subtraction Property of Equality; d. Division Property of Equality; e. Symmetric Property of Equality

Step-by-step explanation:

Given expression,

$11x - 6y = -1; x = 8$

By substituting x = 8,

$11(8) - 6y = -1$

$88 - 6y =-1$

By subtraction property of equality,

$-6y = -89$

Division property of equality,

$y = \frac{89}{6}$

By symmetric property of equality,

$\frac{89}{6} = y$

Answer:

$\frac{sin (c)}{AB}=\frac{sin(A)}{26}$

$sin(A)=\frac{26\times sin(13)}{6} =0.97$

$A=sin^{-1}(0.97)=\boxed{77^o}$

What is the equation 8x-3y=6-4x in Stanford form?

IgorLugansk [536]

Answer:

$12x - 3y = 6$

Step-by-step explanation:

Standard form is written this way: $Ax+By=C$

However, in this case, we just have to simplify 8x-3y=6-4x, as it is already mostly in standard form.

So, to do this, we have to combine like terms.

The only like terms that can be combined are -4x and 8x.

So, we add 4x to both sides, and we get: $12x - 3y = 6$ .

A parent increases a child’s monthly allowance by 20% each year. If the allowance is $8 per month now, in about how many years w

Mazyrski [523]

6 years

A parent increases a child’s monthly allowance by 20% each year. If the allowance is $8 per month now. This is an exponential function, An exponential function is given by:

Let x be the number of years and y be the allowance. The initial allowance is $8, this means at x = 0, y = 8

Since it increases by 20% each year, i.e 100% + 20% = 1 + 0.2 = 1.2. This means that b = 1.2
Therefore:

To find the number of years will it take to reach $20 per month, we substitute y = 20 and find x

x = 6 years to the nearest year
