Answer:
x = 90 / 3
Step-by-step explanation:
Given : 3 candies cost 90 cents
Given this we want to determine the cost of 1 candy.
To find the cost of "something" given the cost of multiple quantities of that "something" we simply divide the total price by the # of products.
Here the total price is 90 cents and the # of products is 3 ( 3 candies )
This means that the cost of 1 candy ( x ) would be = to 90 / 3
Answer:
y = x - 8
Step-by-step explanation:
The equation of the straight line which is perpendicular to the straight line y = -x -3, will be y = x + c' ....... (1), where c' is a constant.
{This is because the product of the slopes of two mutually perpendicular straight line is -1}
Now, (3,-5) point satisfies equation (1).
Hence, -5 = 3 +c', ⇒c' = -8.
Therefore, the equation of the required straight line in slope-intercept form is y = x - 8 (Answer)
{Note: The slope-intercept form of a straight line is y = mx + c, where m is the slope of the line i.e. tanФ, and c is the length of y-axis intercept.}
Answer: C. 5/6
Steps:
Use the formula x1-x2/y1-y2 to find the slope
(5,11), (-5,-1)
-5-5/-1-11
= -10/-12
=5/6
Answer:
the quickest way would be to "complete the square"
on x^2 + 5x - 7
you will end up with (x+2.5)² = 13.25
or
y = (x+2.5)²-13.25
the vertex
VERTEX: (-2.5,-13.25)
Solution/X-Intercepts: -6.14 AND 1.14
Step-by-step explanation:
x and y coordinates. hope it helped
