Suppose y varies directly with x. Write an equation relating x and y.
y = −30 when x = 6
a.
y = −5x
c.
y = −36x
b.
y = 5x
d.
y = 36x
9514 1404 393
Answer:
a. y = -5x
Step-by-step explanation:
The different signs of x and y tell you the constant of proportionality will be negative (eliminating choices b and d).
A quick trial of the given values shows that choice c is incorrect, and that choice a is correct.

two positive real numbers differ by one and have a product equal to one. Find the value of the smaller number to the nearest hundredth
Answer:
1.62
Step-by-step explanation:
smaller number: y
x - y = 1 x = y+1
xy = 1
(y + 1) * y = 1
y² + y - 1 = 0
y = (-1 ± √(1² - 4 * 1 * -1)) / 2 = (-1 ± √5) / 2
small number: (-1 - √5) / 2 = - 1.62

In the plane, if a line is perpendicular to a circle's radius at its outer endpoint, then the line is _____(what) to that circle
a. Diameter
b. Parallel
c. Secant
d. Symmetric
e. Tangent
Random Question for fun... Enjoy!
Answer:
It is B i think i hope this helps
Step-by-step explanation:
If a line is perpendicular to a circle's radius at its outer endpoint, then the line is _Tangent_ to that circle.
What is tangent to a circle?A line segment which touches a circle specified to only one point is called a tangent to that circle.
A line segment is a straight line with finite length, and thus, have to endpoints(points on either ends).
If there is circle O with tangent line L intersecting the circle at point A, then the radius OA is perpendicular to the line L.
We need to find the if a line is perpendicular to a circle's radius at its outer endpoint, then the line is _____(what) to that circle.
If a line is perpendicular to a circle's radius at its outer endpoint, then the line is _Tangent_ to that circle.

Answer:
Freddie would have walked 25 miles after 12 and a half hours.
Step-by-step explanation:
Given that Freddie is walking at a constant speed, and after 2 hours he walked 4 miles, while after 4 hours he walked 8 miles, to determine how long he walked 25 miles, the following calculation must be performed:
4/2 = Miles per hour
2 miles per hour
2X = Y
2X = 25
X = 25/2
X = 12.5
Therefore, Freddie would have walked 25 miles after 12 and a half hours.

Describe the transformation f(x) = Vx+ 1 - 5 in words.
The parent function f(x) = V has been shifted
1 unit and
5 units
Answer:
The translation is 1 unit to the left and 5 units down
Step-by-step explanation:
The explanation is given below;
Given that
The transform function is [tex]f(x) = \sqrt{x+1} - 5[/tex]
It can be seen that
The parent function is
[tex]f(x) = \sqrt{x}[/tex]
After that
The parent function would be transform 1 units to the left [tex]\sqrt{x+1}[/tex]
And afterwards it would be transform in 5 units down [tex]\sqrt{x+1} - 5[/tex]
So
The parent function [tex]f(x) = \sqrt{x}[/tex] would be translate in 1 unit to the left and 5 units down
Answer:
The translation is 1 unit to the left and 5 units down

Find the graph of the inequality
A. Graph A
B. Graph B
C. Graph C
D. Graph D
Answer:
Graph A
Step-by-step explanation:
Based on the inequality shown, you know that the graphed line needs to be both solid and must be shaded above. This is because of the equal to or greater than sign that points toward the y. So, from that you can cancel out b and c because neither are shaded above the line. Then, you can further cancel out d because it has a dashed and not solid line.

The regular price of a chair is $175.90. Find the sale price of the chair
If the regular price is reduced by 10 %, and the new price is then reduced by 15%
Answer:
134.56
Step-by-step explanation:
I believe the sale price for the chair would be 134.56 hope this helps
Answer:
$ 134.56
Step-by-step explanation:
Regular price = $175 .90
Reduction = 10% of 175.90
= 17.59
Price after reduction = 175.90 - 17.59 = $ 158.31
Second reduction = 15% of 158.31
= 0.15 * 158.31
= 23.7465
= $ 23.75
New price = 158.31 - 23.75
= $ 134.56
