What's the equation of the line perpendicular to y=3x-2 and passes through the point (-9,5)? I'm having a brain freeze and can't remember how to do this... Thanks!
Answers
Answer:
-x/3+2=y
Step-by-step explanation:
m should be -1/3
mx+n=y
-x/3+n=y
(-9,5) should equalize the equation
3+n=5
n=2
SO -x/3+2=y

Use the distributive property.
-3x-15=-9
Now, add 15 on both sides.
-3x=6
Divide both sides by -3 to isolate x.
X=-2

Answer:
Step-by-step explanation:
The product of 12 and y is 12y.
If we increase this product by 11, we get
12y + 11
So the second answer choice is the correct one.

The percentage is the indicating hundredth thus 903 is 43% of 2100.
What is the percentage?
The percentage is defined as a given amount in every hundred. It is a fraction with 100 as the denominator percentage is represented by the one symbol %.
Suppose 903 is 43% of the number x.
Since, any percentage of a number is the hundredth value thus,
43% of x = (43/100)x
(43/100)x = 903
x = 903 x 100/43
x = 2100
Hence "The percentage is the indicating hundredth thus 903 is 43% of 2100".

Answer:
2100
Step-by-step explanation:
43% can be represented as 0.43
%43 of a number equals 903 basically means, x * 0.43 = 903 , you can divide both sides by 0.43 and you will get a result like this x = 903 / 0.43, x = 2100
Condition A: a perimeter of 12 and even-numbered side lengths
Condition B: a side length of 4 inches, a side length of 5 inches, an included angle of 110º, and a perimeter of 11 inches
Condition C: a right triangle with an area less than 13 square inches and odd-numbered leg lengths greater than 1 inch
Condition D: an isosceles triangle with two angles that measure 50º
Answers
Figure out the number of possible triangles that fit condition A. There are 3 possible combinations of three even numbers that sum to 12.Of these three, there is only one where every length is less than the sum of the other two: 4 inches,4 inches, 4 inches. So, there is only one triangle that fits condition A.Figure out the number of possible triangles that fit condition B. Since the perimeter and two side lengths are given, subtract the two side lengths from the perimeter to get the length of the third side.Sketch a triangle with lengths of 2 inches, 4 inches, and 5 inches.From the sketch, the angle between the 4-inch length and 5-inch length has to be the smallest angle. Since it has to be the smallest angle, it cannot be more than a right angle. So, there is zero triangles that fit condition B.Figure out the number of possible triangles that fit condition C. For the area to be less than13 square inches, the product of the legs must be less than 26 square inches. The right triangles with odd-numbered legs greater than 1 inch whose product is less than 26 square inches are shown below.So, three triangles fit condition C.Figure out the number of possible triangles that fit condition D. If two angles of an isosceles triangle measure 50º, the third can be found by subtraction both angle measures from 180º.So, the angle measures must be 50º, 50º, and 80º. There is no condition on the lengths, so there are an infinite number of triangles that fit condition D.Therefore, the conditions in order of greatest possible triangles to least are shown below.condition D, condition C, condition A, condition B
