Through: (-5, -5), slope=2/5

kakasveta [241]

For this case we have that by definition, the equation of a line in the slope-intersection form is:

$y = mx + b$

Where:

m: It is the slope

b: It is the cut point with the y axis

The slope is: $m = \frac {2} {5}$

Thus, the equation is of the form:

$y = \frac {2} {5} x + b$

We substitute the given point and find "b":

$-5 = \frac {2} {5} (- 5) + b\\-5 = -2 + b\\-5 + 2 = b\\b = -3$

Finally, the equation is:

$y = \frac {2} {5} x-3$

Answer:

$y = \frac {2} {5} x-3$

Jimmy is selling bracelets for $1.50. So far she has earned $120. She needs to earn more than $135 in order to meet her goal. Ho

Tema [17]

Selling 90 would reach her goal of $135 so she would need to sell 91 to exceed her goal

135/1.5=90 so 91*1.5=136.5

The figure shows two parallel lines KL and NO cut by the transversals KO and LN.

Sever21 [200]

Answer:

(A)

Step-by-step explanation:

From the given figure, we have to prove whether the two given triangles are congruent or similar.

Thus, From the figure, ∠3=∠4 (Vertically opposite angles)

Since, KL and NO are parallel lines and KO and LN are transversals, then

measure angle 1= measure angle 5 that is ∠1=∠5(Alternate angles).

Thus, by AA similarity rule, ΔKLM is similar to ΔONM.

Thus, Option A that is Triangle KLM is similar to triangle ONM because measure of angle 3 equals measure of angle 4 and measure of angle 1 equals measure of angle 5 is correct.

Four different towns in the same state grew in size due to a revitalization effort. The population of town A grew from 22,000 to

Savatey [412]

Answer:

Town C.

Step-by-step explanation:

Average change of population with time for town A = $\frac{24,500 - 22,000}{4} = \frac{2,500}{4} = 625$

Average change of population with time for town B = $\frac{34,770 - 31,200}{6} = \frac{3,570}{6} = 595$

Average change of population with time for town C = $\frac{22,000 - 18,000}{5} = \frac{4,000}{5} = 800$

Average change of population with time for town D = $\frac{34,100 - 32,000}{3} = \frac{2,100}{3} = 700$

Town C had the greatest average change in population over time (800/yr).
