A^2+b^2=c^2

a^2+9^2=15^2
a^2+81=225
a^2=144
take the square root of each side
a=12

Answer:

a) $\log 52$

b) $\log_57$

Step-by-step explanation:

Use logarithm properties:

$\log_ab+\log_ac=\log_a(b\cdot c)\\ \\\log_ab-\log_ac=\log_a\dfrac{b}{c}$

Then

a) $\log 13+\log 4=\log 13\cdot 4=\log 52$

b) $\log_514-\log _52=\log _5\dfrac{14}{2}=\log _57$

The graph of a line is shown below. What is the equation of the line, in slope-intercept form, that is parallel to this line and

dimulka [17.4K]

Answer:

$y = - \frac{3}{2} x + 1$

Step-by-step explanation:

Slope -intercept form: y= mx +c, where m is the slope and c is the y-intercept.

Parallel lines have the same slope. Let's find the slope of the given line.

Given points: (-2, 0) and (0, -3)

$\boxed{slope = \frac{y1 - y2}{x1 - x2} }$

slope of given line

$= \frac{0 - ( - 3)}{ - 2 - 0}$

$= \frac{0 + 3}{ - 2}$

$= - \frac{3}{2}$

$y = - \frac{3}{2} x + c$

Given that the y- intercept is 1, c= 1.

$y = - \frac{3}{2} x + 1$

What is the x-intercept of the equation y=-5x+1,450?

ladessa [460]

Substitute the value for y as 450

450=-5x+1

Solve for x

450-1=-5x

449=-5x

89.8=-x

x=-89.8
