What is the equation of the following are you sure to scroll down first to see all answer options
Answers
Answer:
Y=-3x+0 or Y=-3x
Step-by-step explanation:
Y=mx+b
m=slope
b=y-intercept (where the line crosses the y axis)
The line crosses the Y axis at (0,0), so:
Y=mx+0 or
Y=mx
Slope:
Rise/run= Change in y/Change is x= 9/-3=-3
So:
Y=-3x+0 or
Y=-3x
Answer: 3x + y = 0
Step-by-step explanation: Remember that slope is represented by
rise over run from one point to the next on our graph.
To get from the point (0, 0) to (3, -9), we go down -9 units
so our rise is -9 and we run 3 units so our run is 3.
Our slope therefore or m = -9/3 or -3.
Our y-intercept is represented by the point where this line
crosses the y-axis which in this case is up 0 units.
So our y-intercept or b = 0.
Since we have the slope and y-intercept of our line,
we can now write its equation in y = mx + b form.
Since m = -3 and b = 0, that gives us y =-3x + 0.
Now we convert this equation to standard form.
Just add 3x to both sides to get 3x + y = 0.
So the equation of this lie is 3x + y = 0.

Answers
Answer: Hi, sorry if I’m late to answering but the answer is 19
Step-by-step explanation:
You divide each number in the equation by 5. So, 5x divided by 5 = 1. We cannot use 5 divided by 5 because it will equal 1 so we ignore that and go to 95 divided by 5 = 19. Therefore, 19 is your answer!!! (Hope this helped)
Kelsea and Landon are playing in a park standing 100 feet away from each other. They both see a bird flying above them. The angles of elevation from each person to the bird are shown. How high is the bird from the ground? Round your answer to the nearest tenth. The angle for landon is 45 degrees the angle for kelsea is 20
Answers
Answer:
26.68 ft
Step-by-step explanation:
Let a represent the distance from Kelsea to the bird and b be the distance from Landon to the bird.
Let x = angle of the bird. Hence:
x + 45 + 20 = 180 (sum of angles in a triangle)
x + 65 = 180
x = 180 - 65
x = 115°
Using sine rule:
[tex]\frac{100\ ft}{sin(115)} =\frac{a}{sin(45)} =\frac{b}{sin(20)} \\\\\frac{100\ ft}{sin(115)} =\frac{a}{sin(45)}\\\\a=\frac{100\ ft}{sin(115)} *sin(45)\\\\a=78\ ft\\[/tex]
Let h = height of the bird to the ground. Since a right angle is formed. hence:
[tex]\frac{h}{sin(20)} =\frac{78}{sin(90)} \\\\h=\frac{78}{sin(90)}*sin(20)\\\\h=26.68\ ft[/tex]

The expression p + 0.08p represents the total cost of an item with an initial price of p, plus an 8% sales tax. What is the total cost of an item with an initial price of $90?
Answers
Answer:
$97.2
Step-by-step explanation:=Given
The expression p + 0.08p
where P= the initial price
let y be the total cost, so that
y=p + 0.08p
for p=$90
y=90+0.08*90
y=90+7.2
y=$97.2
Hence the total cost for a $90 price is $97.2
What is the area of the circle ?
Answers
Answer:
113.04 [tex]m^{2}[/tex]
Step-by-step explanation:
Area of a circle is π x [tex]r^{2}[/tex].
I'm assuming that you're using 3.14 as π.
Since the radius of the circle is 6 m, all you need to do is plug it in!
Area = 3.14 × [tex](6)^{2}[/tex]
Area = 3.14 × 36
Area = 113.04 [tex]m^{2}[/tex], which is the third answer choice.

larger dog, find the smaller dog's weight.
wait ugh i asked the wrong question help pls and thank you
Answers
Answer:
52 7/8 pounds
Step-by-step explanation:
Find the smaller dog's weight by multiplying the larger dog's weight by 0.75:
70.5(0.75)
= 52.875 or 52 7/8 pounds
So, the smaller dog weighs 52 7/8 pounds
The required weight of the smaller dog is 52.875 pounds.
Given that,
Doug has two German Shepherds. The larger dog weighs 70 1/2 pounds. If the smaller dog weighs 75% as much as the larger dog, To find the smaller dog's weight.
In mathematics, it deals with numbers of operations according to the statements.
What is percentages?The percentage is the ratio of the composition of matter to the overall composition of matter multiplied by 100.
Here,
Let the weight of the smaller dog be x,
The weight of the smaller dog is 75% of the larger dog
x = 75% of 70 1/2
x = 0.75 * 70.5
x = 52.875
Thus, the required weight of the smaller dog is 52.875 pounds.

Step-by-step explanation:
Key Skills required are: One Variable Equations, Supplementary Angle Pairs, Substitution, and Triangles.
1) To find the measure of Angle C, we first need to find the measure of angle DBC and Angle D.
2) We are given that Angle EBA is x and Angle EBD is 4x+13 and Angle D is 3x + 9 (we will use Angle D later in the problem)
3) Now, we need to use the fact that Angle EBA and Angle EBD are supplementary (they form a linear pair, so they are supplementary).
A pair of supplementary angles add up to 180 degrees (as they form a straight angle).
4) x + 4x + 13 = 180
5) Combine like terms --> 5x + 13 = 180
6) Move 13 to the other side --> 5x = 167
7) Divide by 5 and solve for x: x= 33.4
8) Now we got that x is 33.4, we can get the measure of angle DBC and Angle D.
9) Angle DBC is congruent to Angle EBA. So to find the measure of DBC we need to find the measure of Angle EBA. EBA is just x, so it is 33.4 degrees
10) Therefore, Angle DBC also measures 33.4 degrees.
11) To find angle D, we substitute x into 3x + 9 (We are given angle D is 3x + 9 based on the problem)
12) 3(33.4) + 9 = 100.2 + 9 = 109.2
13) Now we use the interior angles sum of a triangle to find Angle C.
The interior angles of a triangle sum up to 180 degrees.
14) With the statement above we can make this equation: 109.2 + 33.4 + Angle C = 180
15) Simplify by combining like terms: 142.6 + Angle C = 180
16) 37.4 degrees would be the measure of C, so I feel it would be none of the above.
