Step-by-step explanation:
Hi there!
Since the dot is in the fourth quadrant, our x value will have to be positive. If the value was negative, it would be in the third quadrant.
If you think about the dot’s relation to the y axis, it is below the point of origin, or y = 0, so the y-value will have to be negative.
The only answer that fits this criteria is (3,-5)

4y -9x =-23 x=y-3 what is the y-value
Answer:
y = 10
Step-by-step explanation:
Use the substitution method since you already know what x equals.
4y - 9(y - 3) = -23
Simplify:
4y - 9y + 27 = -23
Combine like terms:
-5y + 27 = -23
Isolate y by subracting 27 from both sides:
-5y = -50
Divide by -5 to get y by itself:
-5/-5 = y
-50/-5 = 10
what is the formula to calculate velocity?
Answer:
Velocity (v) is a vector quantity that measures displacement (or change in position, Δs) over the change in time (Δt), represented by the equation v = Δs/Δt. Speed (or rate, r) is a scalar quantity that measures the distance traveled (d) over the change in time (Δt), represented by the equation r = d/Δt.

At Martin Luther King Jr. High School 7 out of 9 students voted to plant trees at the front of the school. A total of 119 voted to plant the trees. How many students voted?
A. 153
B. 272
C. 128
D. 135
Answer:
A
Step-by-step explanation:
If 7 out of 9 voted to plant, that means 2 voted against
so the ratio we are looking at here for vote for and vote against is 7:2
So let the total that voted be x
7/9 * x = 119
x = (9 * 119)/7
x = 153

Find the measure of angle A.
x + 47
780
x + 61
A) 31°
B) 44°
C) 51°
Answer:
180 degrees in a triangle
180 - 78 - 47- 61 = -6
2X = -6
-6/2 = -3
-3 + 47 = 44
-3+61= 58
78 + 58 + 44= 180
A = 44 degrees

The inequality describes all possible value of x is 14 < x < 32 ⇒ D
Step-by-step explanation:
In any triangle:
The sum of the lengths of any two sides must be greater than the length of the 3rd sideThe length of any side must greater than the difference of the lengths of the other two sidesThe difference of the other sides < The side < The sum of the other sidesIn the given figure
∵ ABC is a triangle
∵ AC = 9 and BC = 21
∵ AB is the third side of the triangle
→ By using the rules above
∴ BC - AC < AB < BC + AC
∵ AB = x - 2
→ Substitute their values in the inequality above
∵ 21 - 9 < x - 2 < 21 + 9
∴ 12 < x - 2 < 30
→ Add 2 to the 3 terms
∴ 12 + 2 < x - 2 + 2 < 30 + 2
∴ 14 < x < 32
∴ The inequality describes all possible value of x is 14 < x < 32

Triangle ABC is similar to triangle DEF What are the lengths of sides DF and EF ?
Answer:
A)
Side DF=3
Side EF=6/5
Bye
The values of DF and EF are 3 and 6/5 respectively. (option A)
What are similar triangles?When two triangles are similar, then their corresponding angles are congruent and corresponding sides are in equal proportion.
Given that, Δ ABC ~ Δ DEF
The proportion = AB/DE = BC/EF = AC/DF = 5/3
2/EF = 5/3
EF = 6/5
5/DF = 5/3
DF = 3
Hence, The values of DF and EF are 3 and 6/5 respectively. (option A)

The value of computer decreases with its age until it is worth nothing a computer that was purchases new for 0 years is worth 2220 1540 after 6 years problem whats the value after 8 years and what is the linear function V(x)
Answer:
[tex]V(x) = -\frac{340}{3}x +2220[/tex]
[tex]V(8) = 1313.3[/tex]
Step-by-step explanation:
Given
Let x represent years and V represents the value.
So, we have:
[tex](x_1,v_1) = (0,2220)[/tex]
[tex](x_2,v_2) = (6,1540)[/tex]
Solving (a): The linear function
First, we calculate the slope (m)
[tex]m = \frac{v_2 - v_1}{x_2 - x_1}[/tex]
This gives:
[tex]m = \frac{1540-2220}{6-0}[/tex]
[tex]m = \frac{-680}{6}[/tex]
[tex]m = -\frac{340}{3}[/tex]
The linear function is calculated using:
[tex]v - v_2 = m(x - x_2)[/tex]
Where:
[tex](x_2,v_2) = (6,1540)[/tex]
[tex]m = -\frac{340}{3}[/tex]
So, we have:
[tex]v - 1540 = -\frac{340}{3}(x - 6)[/tex]
Open bracket
[tex]v - 1540 = -\frac{340}{3}x +\frac{340}{3}* 6[/tex]
[tex]v - 1540 = -\frac{340}{3}x +680[/tex]
Make v the subject
[tex]v = -\frac{340}{3}x +680+1540[/tex]
[tex]v = -\frac{340}{3}x +2220[/tex]
So, the function is:
[tex]V(x) = -\frac{340}{3}x +2220[/tex]
Solving (b): When x = 8
Substitute 8 for x in [tex]V(x) = -\frac{340}{3}x +2220[/tex]
[tex]V(8) = -\frac{340}{3}*8 +2220[/tex]
[tex]V(8) = -\frac{340*8}{3} +2220[/tex]
[tex]V(8) = -\frac{2720}{3} +2220[/tex]
Take LCM
[tex]V(8) = \frac{-2720+2220*3}{3}[/tex]
[tex]V(8) = \frac{-2720+6660}{3}[/tex]
[tex]V(8) = \frac{3940}{3}[/tex]
[tex]V(8) = 1313.3[/tex]
Hence, its value after 8 years is 1313.3
