Answer:
f(3)=-11
in other words
When x=3, y=-11
Step-by-step explanation:
f(x)=-3x-2
f(3)=-3(3)-2
f(3)=-9-2
f(3)=-11
If f(x)=x-3, which inequality can be used to find the domain of f(x)?
Ovx-3>0
O x-3>0
O vx-3 <0
O x-3<0
Given that,
[tex]f(x) = \sqrt{x-3}[/tex]
To find,
The domain of f(x).
Solution,
We have, [tex]f(x) = \sqrt{x-3}[/tex]
To find domain,
The term under the square root must be positive or null as follows :
[tex]x-3\ge 0[/tex]
Adding 3 both sides
[tex]x-3+3\ge 0+3\\\\x\ge 3[/tex]
So, the domain is x-3>0 .
Point T T is located at ( − 1 , − 4 ) (−1,−4) on the coordinate plane. Point T T is reflected over the x x-axis to create point T ′ T ′ . Point T ′ T ′ is then reflected over the y y-axis to create point T ′ ′ T ′′ . What ordered pair describes the location of T ′ ′ ? T ′′ ?
Given:
The point is located at (-1,-4).
Point T is reflected over the x-axis to create point T′.
Point T′ is then reflected over the y-axis to create point T′′.
To find:
The ordered pair describes the location of T''.
Solution:
We have, the given point T(-1,-4).
Point T is reflected over the x-axis to create point T′. So, the rule of reflection is
[tex](x,y)\to (x,-y)[/tex]
[tex]T(-1,-4)\to T'(-1,4)[/tex]
Point T′ is then reflected over the y-axis to create point T′′. So, the rule of reflection is
[tex](x,y)\to (-x,y)[/tex]
[tex]T'(-1,4)\to T''(1,4)[/tex]
Therefore, the ordered pair (1,4) escribes the location of T′′.

Find x please this is so difficult
Answer:
x= 19
Step-by-step explanation:
∠ WYZ and ∠ XWY are alternate angles and are congruent, so
∠ XWY = 2x
The sum of the 3 angles in a triangle = 180°
sum the angles in Δ XWY and equate to 180
2x + 3x - 5 + 90 = 180
5x + 85 = 180 ( subtract 85 from both sides )
5x = 95 ( divide both sides by 5 )
x = 19

Find the inequality represented by the graph.
Answer:
[tex]y<-\frac{4}{3}x+5[/tex]
Step-by-step explanation:
Since, the given line in the graph is a dotted, line will represent an inequality with no sign of equal to (=).
Since, the shaded area is below the dotted line, inequality will have the sign less than (<).
Therefore, equation of the inequality will be in the form of,
y < mx + b
Here, m = slope of the line
b = y-intercept
Slope of the line passing through two points (0, 5) and (3, 1),
m = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
= [tex]\frac{5-1}{0-3}[/tex]
= [tex]-\frac{4}{3}[/tex]
Y-intercept (at x = 0),
b = 5
Therefore, equation of the inequality will be,
[tex]y<-\frac{4}{3}x+5[/tex]

Which of the following is not represented in the image below?
4.
Line segment BC
Ray CA
Point
Ray DB
Answer:
Ray CA
Step-by-step explanation:
There is a point in-between.
A ray cannot depict CA because it extends from both of its ends.
Option 2 is correct.
What is a Ray?In mathematics, a ray is a segment of a line with a fixed starting point but no ending. That can go on forever in a single direction. A ray cannot be measured since it has no end point.
Point: Point is a dot or vertex of any figure or diagram. It represents by capital alphabet. So, B would be a point.
Line: A line is a straight path with both endless. It means we can extends line from both end. But in case of BD we can't extend from point B. So, it won't be a line.
Ray: A ray is a straight path with one endless. It means we can't extend line from one end and extend from another end. But we can extend AC from both end. It won't be a ray.
Line Segment: A line segment is a straight path with end from both end. We can't extend from either end of the line. We can say CD would be line segment.
CA cannot be represented by a ray, as it's extending from both of its ends.

stephanie and jenny each improved their yards by planting rose bushes and geraniums. they bought their supplies from the same store. stephanie spent $148 on 13 rose bushes and 1 geranium. jenny spent $169 on 9 rose bushes and 14 geraniums. find the cost of one rose bush and one geranium.
Answer:
The cost of one rose is $11., and the cost of one geranium is $5.
Step-by-step explanation:
The cost of one rose bush and one geranium can be determined by the use of simultaneous equation. Let the cost of a rose bush be represented by x, and the cost of one geranium by y.
So that,
13x + y = 148 .............. 1
9x + 14 y = 169 ............... 2
From eqaution 1,
y = 148 - 13x ............... 3
substitute the value of y in equation 2
9x + 14(148 - 13x) = 169
9x + 2072 - 182x = 169
2072 - 169 = 182x - 9x
1903 = 173x
x = [tex]\frac{1903}{173}[/tex]
= 11
x = 11
substitute the value of x in equation 3
y = 148 - 13x
= 148 - 13(11)
= 148 - 143
y = 5
x = 11, y = 5
Thus, the cost of one rose is $11., and the cost of one geranium is $5.

In the seating for a concert, the first row has 10 chairs. Every row after that has 2 more chairs. 7. What is the explicit formula that models this situation? 8. How many chairs are in row 20?
9514 1404 393
Answer:
7. c(n) = 10 +2(n -1)
8. c(20) = 48
Step-by-step explanation:
7. Your arithmetic sequence has first term a1=10 and constant difference d=2. The explicit formula for terms of an arithmetic sequence is ...
an = a1 +d(n -1)
If we use c(n) as the function name for the function giving the number of chairs in row n, then we can fill in the numbers we know to get ...
c(n) = 10 + 2(n -1)
__
8. Evaluating the function when n=20, we find ...
c(20) = 10 +2(10-1) = 10 +2·19 = 10 +38
c(20) = 48
There are 48 chairs in row 20.
what is the prime factorization of 100
Answer:22 × 52
Step-by-step explanation:
Answer:
2 x 2 x 5 x 5
Step-by-step explanation:
since 2, 3, and 5 are prime numbers I always begin by seeing if the number to be factored has those as factors
100 is divisible by 2 so you can start there:
2 x 50
50 is divisible by 2 so you now have:
2 x 2 x 25
25 is divisible by 5 so you now have all prime factors whose product is 100
2 x 2 x 5 x 5
The sum of the measures of two adjacent angles is 72 degrees. The ratio of the smaller angle to the
larger angle is 1:3. Find the measure of the larger angle.
Answer:
The larger angle is 54°
Step-by-step explanation:
Given
Let the angles be: θ and α where
θ > α
Sum = 72
α : θ = 1 : 3
Required
Determine the larger angle
First, we get the proportion of the larger angle (from the ratio)
The sum of the ratio is 1 + 3 = 4
So, the proportion of the larger angle is ¾.
Its value is then calculated as:.
θ = Proportion * Sum
θ = ¾ * 72°
θ = 3 * 18°
θ = 54°
