liq [111]

Answer:

$\displaystyle x = 3.97$

Step-by-step explanation:

we are given a exponential equation

$\displaystyle {3}^{x} = 78$

we want to figure out x

remember that,

$\displaystyle \log_{a}( {a}^{c} ) = c$

thus

take $\log_3$ both sides:

$\displaystyle \log_{3}( {3}^{x} ) = \log_{3}(78)$

use the formula:

$\displaystyle x = \log_{3}(78)$

by using calculator

$\displaystyle x = 3.97$

9th grade alg 1 number 43 and work please!

Darya [45]

Answer:

The rule is y = -7x + 5

→ Other values of x;

-9

→ Other values of y;

5
-2
-9
-12
28
68
-170

Step-by-step explanation:

» Take points (1, -2) and (3, -12) from the table.

☑ General equation of a line is y = mx + c

m is the slope
c is y-intercept

✍ For slope, m :

${ \tt{slope = \frac{ - 12 - 2}{3 - 1} }} \\ \\ { \tt{slope = \frac{ - 14}{2} }} \\ \\ { \tt{m = - 7}}$

✍ For y-intercept, c :

${ \tt{y = mx + c}}$

» Taking point (1, -2):

${ \tt{ - 2 = (1 \times - 7) + c}} \\ { \tt{c = - 2 + 7}} \\ { \tt{c = 5}}$

${ \boxed{ \tt{y = - 7x + 5}}}$

ASAP help me with this ty!

iren2701 [21]

Answer:

96 degrees

Step-by-step explanation:

The angle bisectors splits the two angles mentioned down the middle so the 2 angles are equal to each other.

4x + 4 = 2(x + 13) Distribute the 2

4x + 4 = 2x + 26 Subtract 2x from both sides

2x + 4 = 26 Subtract 4 from both sides

2x = 22 Divide both sides by 2

x = 11 Plug that back into either the right side or the left side of the original equation

4x + 4

4(11) + 4

44 + 4

48. Each angle is 48 degrees. 48 + 48 is 96

Determine whether the pair of equations represent parallel lines, perpendicular lines, or neither.

Ivahew [28]

Answer:

Parallel

Step-by-step explanation:

Parallel lines have the same slope but different y-intercepts. If you multiply the top equation by 2, you get:

2(12x + 4y = 16)

24x + 8y = 32

This shows that both lines have the same slope, but then you find the y-intercepts, they are different:

1st equation y-int = 4

2nd equation y-int = 9/2 or 4.5
