Answer:
The value of r is 16
Step-by-step explanation:
<u><em>The correct question is</em></u>
Find out the value of r if the slope between the two ordered pairs is m=-1/5
we know that
The formula to calculate the slope between two points is equal to
we have the points
(r, 7), (11, 8)
substitute the values
Remember that
equate the equations
solve for r
Multiply in cross
Im sorry but i dont understand your question. can you be more pacific.
Answer:
1/9
Step-by-step explanation:
first, u need 9 ---> 1/3
then u need 8 ---> 1/3 also
Multiply them and get...1/9
2^1 because when you times indices you add the indices and when you divide you subtract it
Answer:
a) x = 62
b) x = 33
Step-by-step explanation:
Hi there!
a) Let´s write the equation:
√(2x-3) = 11
Square both sides
2x - 3 = 121
add 3 to both sides of the equation
2x = 124
divide by 2 both sides
x = 62
Let´s check:
√(2x-3) = 11
x = 62
√(2(62)-3) = 11
√(124-3) = 11
√121 = 11
11 = 11
x = 62 satisfies the equation
b) Let´s write the equation:
∛(6 - x) = -3
Cube both sides
6 - x = -27
subtract 6 to both sides
-x = -27 - 6
-x = -33
divide by -1 both sides
x = 33
Now, let´s check the result:
∛(6 - x) = -3
x = 33
∛(6 - 33) = -3
∛(-27) = -3
-3 = -3
x = 33 satisfies the equation
