find the equation that represents the proportional relationship in this graph
Answers
Answer:
y = 4/5x
Step-by-step explanation:
Points on the graph: (5, 4) and (0, 0)
Slope:
m=(y2-y1)/(x2-x1)
m=(0-4)/(0-5)
m=(-4)/(-5)
m= 4/5
Slope-intercept:
y - y1 = m(x - x1)
y - 4 = 4/5(x - 5)
y - 4 = 4/5x - 4
y = 4/5x

Loren is running in a long distance race. She is able to keep a steady pace of 10 feet per second.
Answers
Answer:
a or c Im not sure
Step-by-step explanation:
I think b though
The line which represents the speed as 10 feet per second is line B thus none of the given options are correct.
What is a graph?A graph is a diametrical representation of any function between the dependent and independent variables.
For example y = x² form a parabola now by looking at only the graph we can predict that it has only a positive value irrespective of the interval of x.
As per the given,
Loren is running at speed of 10 feet per second.
Speed = distance covered/time taken
10 = distance covered/time taken
In line B, the ratio of distance covered/time taken is 10.
Thus, line B will be correct.
Hence "The line which represents the speed as 10 feet per second is line B thus none of the given options are correct".

please help me, I'm stuck on the second one. Also for i) i got angle ABD because angles in a semicircle measures 90 degree and OAX because the angle between the tangent and a radius is 90 degrees
Answers
Answer:
i)
DA is diameter and AX is tangent to circleYour answer is correct
m∠ABD = 90°, m∠DAX = 90°ii)
Given m∠BAX = 42° and ∠DAB is complementary with BAX ⇒
m∠DAB = 90° - 42° = 48°DC = BC ⇒ intercepted arcs are same ⇒
∠CDB = ∠BDCmDC = mCB ⇒ mDCB = ∠DAB = 48° ⇒
m∠CDB = m∠BDC = 1/2*48 = 24°iii)
∠CBA
∠CBA is supplementary with ∠ADC as opposite angles of cyclic quadrilateral (∠ADB = ∠BAX = 42°)
m∠ADC = m∠ADB + m∠CDB = 42° + 24° = 68°m∠CBA = 180° - m∠ADC = 180° - 68° = 112°∠BAE
EA║CB and AB is transversal ⇒ CBA and BAE are supplementary angles:
m∠BAE = 180° - 112° = 68°∠DCE
∠DCE = ∠DCB - ∠BCEm∠DCB = 180° - m∠DAB = 180° - 48° = 132°m∠BCE = 180° - m∠BAE = 180° - 68° = 112°∠DCE = 132° - 112° = 20°-8x-10=4x+14 show your work

D. Two cities that are actually 66 km apart are 9.9 cm apart on the map.
Step-by-step explanation:
Step 1
Indicate the scale as shown;
3 cm : 20 km, meaning 3 cm on the map represents 20 km on the ground
A). what does 7.5 cm represent on the ground
Distance on ground=(7.5×20)/3=50 km
B). what does 4 cm represent on the ground
Distance on ground=(4×20)/3=26.67 km
C). what does 45 km on ground represent on the map

The cost of the hiking trip this year is 2/3of the cost of last year's trip. This year's trip cost $32
1. Write an equation that represents the cost of last years trip.
2.What was the cost of last year's trip
Answers
Answer:
The equation is ( 32/2 ) × 3 = 48.
Step-by-step explanation:
In order to find the answer, we must find one third of last years trip. To do this, we can simply divide the cost of this year's trip by two, 32/2=16.
Now if we multiply this years trip by 3, 16×3=48, we can see that the total cost of last years trip was $48.
If we'd like to turn this into a equation, it looks like this:
( 32/2 ) × 3 = 48.

Someone pls help I will pay if you get it right
Answers
Given:
The graph of a trend line.
To find:
The equation of the trend line.
Solution:
From the given graph it is clear that the trend line passes through the points (0,4) and (9,7). So, the equation of the trend line is:
[tex]y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)[/tex]
[tex]y-4=\dfrac{7-4}{9-0}(x-0)[/tex]
[tex]y-4=\dfrac{3}{9}(x)[/tex]
[tex]y=\dfrac{1}{3}x+4[/tex]
Therefore, the equation of the trend line is [tex]y=\dfrac{1}{3}x+4[/tex].

= ?/?, or ?
the slope is ___
Answers
Answer:
5
Step-by-step explanation:
You can find the slope with rise over run. Rise means up and run means moving right or left. In this case rise is 10 and run is 2. This means the fraction will look like 10/2. Simplify this to get 5 and that is your answer.
Hope this helps.

Solve for x, 2-x= -6-4x
a . -2/3
b.-2/5
c-8/3
d.-8/5
Answers
Answer:
-8/3
Step-by-step explanation:
2 - x = - 6 - 4x <-- Add 4x to the left side
2 + 3x = - 6 <-- Subtract 2 from the left side
3x = -8 <-- Divide 3 on both sides
x = -8/3
Answer:
x = -8/3
Step-by-step explanation:
Consolidate x terms on the right side:
2-x= -6-4x becomes 2-x + x = -6-4x + x, which in turn becomes:
2 = -6 - 3x, or 3x = -8. Then, dividing both sides by 3, we get x = -8/3
