Hello!

Step-by-step explanation:

Slope: $\frac{Y^2-Y^1}{X^2-X^1}=\frac{rise}{run}$

$\frac{9-3=6}{2-(-1)=2+1=3}=\frac{6}{3}=2$

Therefore, the slope is 2.

Answer is 2.

Hope this helps!

Thank you!

Answer:

12. a = 2

13. $x = \dfrac{4}{3}$

Step-by-step explanation:

12.

6a(a + 3) = 2a(3a + 5) + 16

First, distribute 6a on the left side, and distribute 2a on the right side.

6a² + 18a = 6a² + 10a + 16

Subtract 6a² from both sides.

18a = 10a + 16

Subtract 10a from both sides.

8a = 16

Divide both sides by 8.

a = 2

13.

$\dfrac{1}{3}x + \dfrac{1}{2}x = \dfrac{1}{3}(x + 2)$

The LCD of 2 and 3 is 6. We multiply both sides of the equation by 6 to get rid of all denominators.

$6 \times \dfrac{1}{3}x + 6 \times \dfrac{1}{2}x = 6 \times \dfrac{1}{3}(x + 2)$

$\dfrac{6}{3}x + \dfrac{6}{2}x = \dfrac{6}{3}(x + 2)$

$2x + 3x = 2(x + 2)$

Combine like terms on the left side. Distribute the 2 on the right side.

$5x = 2x + 4$

Subtract 2x from both sides.

$3x = 4$

Divide both sides by 3.

$x = \dfrac{4}{3}$

Log*subscript*(3x − 2) 4096 = 3 I got x= negative 6 is this correct??

Brut [27]

Remember

$log_a(b)=c$ translates to $a^c=b$
and
$log_a(b^c)=clog_a(b)$
so

4096=16^3
$log_{3x-2}(4096)=3$
$log_{3x-2}(16^3)=3$
$3log_{3x-2}(16)=3$
divide both sides by 3
$log_{3x-2}(16)=1$
translate
$(3x-2)^1=16$
3x-2=16
add 2 to both sides
3x=18
divide both sides by 3
x=6

What does x/4=3/2 equal?

MrRissso [65]

x/4 = 3/2
x/2 = 3 (multiply both sides by 2)
x = 6 (multiply both sides by 2)
Therefore 6/4 = 3/2

The ratio of boys to girls in history class is 4 to 5. How many girls are in the class if there are 12 boys in the class. Show y

Natalija [7]

I believe its 15 girls.
If its 5 girls to every 4 boys and there is 12 boys then 12 is just 4 three times so you would do 5 three times making it 15.
4boys = 5girls
+4boys= 5girls
+4boys = 5girls
=12boys = 15girls
