Answer:
y < -1/4 x +1
Step-by-step explanation:
Find two points on the dotted line
( 0,1) and (4,0)
We can use the slope formula
m = ( y2-y1)/(x2-x1)
= (0-1)/(4-0)
= -1/4
The slope is -1/4
The y intercept is where it crosses the y axis or 1
The equation of the line, using slope intercept form
y = mx+b
y = -1/4x +1
The line is dotted which means there is no equals, just greater than or less than. It is shaded below which means less than
y < -1/4 x +1
Answer:
[tex]y<-\frac{1}{4}x+1[/tex]
Step-by-step explanation:
First, let's find the equation of the line.
From the graph, we can pick out two points to use: (0,1) (the y-intercept) and (4,0) (the x-intercept).
Find the slope. Let (0,1) be x₁ and y₁ and let (4,0) be x₂ and y₂
Find the slope:
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
Substitute:
[tex]m=\frac{0-1}{4-0}\\m=-1/4[/tex]
Use the slope-intercept form:
[tex]y=mx+b[/tex]
Where m is the slope and b is the y-intercept.
We already know the slope is -1/4 and the y-intercept is 1. So, substitute:
[tex]y=-\frac{1}{4}x+1[/tex]
Now, replace the equal sign with an inequality. Note that the line is dotted, so we won't use "or equal to." Also note that the blue, shaded area is below the line. Thus, we will use less than. Therefore:
[tex]y<-\frac{1}{4}x+1[/tex]
The sentences:
First, we picked out two points from the graph. Next, we used those two points to find the slope. We used the slope and one of the points to write our slope-intercept equation. Afterwards, we can determine from the graph that since the shaded area is below the dotted line, the equation must have a less than.

It is a customer appreciation week at the vans shoe outlet, Which means all customers are given a 20% discount on all items. A customer comes in with an birthday coupon for an additional 10% off any shoe item, once the first discount has been applied. The customer buys 3 pairs of shoes for $120.00 each. After the two discounts how much does the customer pay?
Answers
Answer:
$278.40
Step-by-step explanation:
Note: "...an additional 10% off any shoe item, once the first discount has been applied." (emphasis added).
Note that the customer is buying 3 pairs of shoes for $120 each: 120 x 3 = $360
The first discount is the 20% discount (on every single item), the second discount is the 10% discount coupon of of any item (which signifies one item only).
Solve for the first discount:
$360 x 0.20 = $72
$360 - 72 = $288.
Next, divide $288 by 3 (to get the individual prices of the shoes:
$288/3 = $96.
The customer then uses a birthday coupon for one of the shoes, which gives an additional 10% off.
$96 x 0.10 = 9.6
$96 - 9.6 = $86.4
Remember, the other two shoes still cost $96 each. Add the price together:
$96 + $96 + $86.4 = $278.40
$278.40 will be the total.

Answer:
[tex]x=2,8[/tex]
Step-by-step explanation:
So we have the equation:
[tex]1+3|x-5|=10[/tex]
First, subtract 1 from both sides:
[tex]3|x-5|=9[/tex]
Now, divide 3 from both sides:
[tex]|x-5|=3[/tex]
Definition of absolute value:
[tex]x-5=3\text{ or }x-5=-3[/tex]
For the left, add 5 to both sides.
For the right, add 5 to both sides:
[tex]x=3+5\text{ or } x=-3+5\\x=8\text{ or }x=2[/tex]
Thus, the answers are:
[tex]x=2,8[/tex]
What is the image of the point (8, -3) after a rotation of 90° counterclockwise about
the origin?
Answers
Answer:
[tex]\huge\boxed{(3, 8)}[/tex]
Step-by-step explanation:
When we rotate a point 90° counterclockwise around the origin, it's the same as rotating it 270° clockwise around the origin.
When we rotate something 270° clockwise around the origin, the original coordinates (x, y) becomes (-y, x).
y is -3, and -(-3) is just 3, since two negatives make a positive.
x just remains x, but it's in a different position.
This makes the new coordinate [tex](3, 8)[/tex].

Domain: [tex](-\infty,\infty)[/tex]
Range: [tex](1,\infty)[/tex]
Step-by-step explanation:
The domain of a function is the span of x-values it covers.
The range of a function is the span of y-values it covers.
From the graph, we can see that the domain stretches infinitely in both directions. Therefore, the domain is all real numbers.
In interval notation, this is:
[tex](-\infty,\infty)[/tex]
For the range, note that horizontal line at y=1.
The dotted line tells us that there is a horizontal asymptote there. In other words, y would never reach exactly 1.
Thus, our range would be all values greater than 1 (to positive infinity).
In interval notation, this is:
[tex](1,\infty)[/tex]

Step-by-step explanation:
Given g(x)=3x2+3 find x if g(x)=78 = 5
Hope this helped you :)
Answer:
x = ± 5
Step-by-step explanation:
Given
g(x) = 3x² + 3 and g(x) = 78 , then equate the right sides, that is
3x² + 3 = 78 ( subtract 3 from both sides )
3x² = 75 ( divide both sides by 3 )
x² = 25 ( take the square root of both sides )
x = ± [tex]\sqrt{25}[/tex] = ± 5
That is x = - 5 or x = 5

In a theater, there are 20 chairs in the first row, each row has 4 more chairs than the previous row, and there are 15 rows. How many chairs are there in the theater?
Answers
Answer:
There are a total of 720 chairs in the theater
Step-by-step explanation:
First row = 20 chairs

The given is an arithmetic progression (A.P)
First term
a = 20
Common difference
d = 4
Number of terms
n=15
Sum of the chairs in the theater with a total of 15 rows
Sum of an A.P = n/2 { 2a + (n-1) d}
= 15/2{ 2*20 + (15-1) 4}
= 7.5 { 40 + (14) 4 }
= 7.5 { 40 + 56}
= 7.5(96)

Acceleration = Change in velocity / time taken = (Final velocity - Initial velocity) / time
Given that the acceleration is 2160 deg/min², we have to convert it to deg/s²
