lozanna [386]3 years ago
6 0

Answer:

x = ± 5

Step-by-step explanation:

x² - 25 = 0 ( add 25 to both sides )

x² = 25 ( take square root of both sides )

x = ± \sqrt{25} = ± 5

That is x = - 5, x = 5

The map of a walking trail is drawn on a coordinate grid with three points of interest. The trail starts at R(−2, 4) and goes to
Bogdan [553]
Length from R(-2, 4) to S(3, 4) is sqrt((3 - (-2))^2 + (4 - 4)^2) = sqrt(5)^2 = 5 units

Length from S(3, 4) to T(3, -1) is sqrt((3 - 3)^2 + (-1 - 4)^2) = sqrt(-5)^2 = 5 units

Therefore, total length = 5 + 5 = 10 units.

How do I solve this equation?
inn [45]
You can use substitution or elimination or graphing to solve the equation. Since both of the equations are in slope intercept form it will be easier to use substitution or to graph it and find the point of interception.

a roller skating rink offers a special rate for birthday parties. On the samr day, a party for 10 skaters cost $107 and a party
olga nikolaevna [1]

Answer:

$119

Step-by-step explanation:

Let

x -----> the number of skaters

y -----> the cost for birthday parties

we have the points

(10,107) and (15,137)

step 1

Find the slope of the linear equation

The formula to calculate the slope between two points is equal to

m=\frac{y2-y1}{x2-x1}

substitute the values

m=\frac{137-107}{15-10}

m=\frac{30}{5}=6\ \frac{\$}{skater}

step 2

Find the equation of the line in point slope form

y-y1=m(x-x1)

we have

m=6\\point\ (10,107)

substitute

y-107=6(x-10)

step 3

Convert to slope intercept form

y-107=6x-60

y=6x-60+107

y=6x+47

step 4

How much would a party for 12 skaters cost?

For x=12 skaters

substitute the value of x in the equation and solve for y

y=6(12)+47

y=\$119
