Answer:

∠7 = 95°

Step-by-step explanation:

∠1 and ∠4 are vertical angles so they are equal.

so:

3x + 10 = 4x - 15

simplify:

x = 25°

∠4 = 4(25) - 15 = 85°

∠8 = ∠4 because they are corresponding angles

∠7 = 180° - 85° = 95° because they are supplementary angles (add together to = 180°)

Define a system of linear inequalities

goblinko [34]

A system of linear inequalities in two variables consists of at least two linear inequalities in the same variables. The solution of a linear inequality is the ordered pair that is a solution to all inequalities in the system and the graph of the linear inequality is the graph of all solutions of the system.

Answer:

(x + 1)² + (y + 1)² = (√6)²

Step-by-step explanation:

Group the x- and y- terms together:

9x^2 + 18x + 9y^2 + 9y = 36

Factor out the coefficient 9:

x^2 + 2x + y^2 + y = 4

Complete the square of x^2 + 2x and then do the same for y^2 + 2y:

x^2 + 2x + 1 - 1 + y^2 + 2y + 1 - 1 = 4

Rewrite x^2 + 2x + 1 as the square of the binomial x + 1:

(x + 1)^2 + (y + 1)^2 - 2 = 4

Collect the constant terms on the right side:

(x + 1)^2 + (y + 1)^2 = 6

Rewrite 6 as (√6)^2:

(x + 1)² + (y + 1)² = (√6)² is the equation in standard form (x - h)² + (y - k)² = r²

Completing the square is done as follows: x^2 + 2x

Start with x^2 + 2x

1. Take half of the coefficient of x, which results in 2/2, or 1

2. Square this result and add it to, and subtract it from x^2 + 2x

x^2 + 2x + 1 - 1

3. Rewrite the first three terms as the square of a binomial:

x^2 + 2x + 1 - 1 = (x + 1)² - 1.

Do the same for y² + 2y.

Solve logarithm Equation: log2 (12b - 21) - log2 (b^2 - 3)=2

Vikki [24]

Hn, well you should use the rule to answer this.. $log_a(n)-log_a(m)=log_a (\frac{n}{m} )$
Sorry if this doesn't seem to help, but here is the explanation:
$log_2 (\frac{12b-21}{b^2-3} )=2$
$\frac{12b-21}{b^2-3} =4$
$12b-21=4(b^4-3)$
$0=4b^2-12b-12+21$
$0=4b^2-12b+9
$
$0=4b^2-6b-6b+9$
$0=2b(2b-3)-3(2b-3)$
$0=(2b-3)(2b-3)$
$b= \frac{3}{2}$
Hn, so from this information we can determine that this solution does not work. And so forth your solution set shall indeed be: {x= 0}

I wish you good luck on your homework and hopefully I was somewhat beneficial to your needs.

Best regards~ Sans
