The straight line 4x+5y-20 = 0 cuts the X-intercept, Y-intercept and hence find area of traingleAOB
Answers
Answer:
The area of the triangle AOB is 10
Step-by-step explanation:
The line 4x+5y-20=0 forms a triangle AOB as shown in the figure below. The points A and B are the y-intercept and x-intercept respectively, and the point O is the origin.
To find the intercepts, we set the other variable to zero and solve the resulting equation.
Set x=0, the y-intercept is found as follows:
4(0)+5y-20=0
5y=20
y=20/5=4
The y-intercept is y=4
Set y=0, the x-intercept is now found:
4x+5(0)-20=0
4x=20
Solve:
x=20/4=5
The x-intercept is x=5
Now, knowing the base b and the height of the triangle h are 5 and 4 respectively, the area of the triangle is:
[tex]\displaystyle A=\frac{bh}{2}[/tex]
[tex]\displaystyle A=\frac{5\cdot 4}{2}=10[/tex]
The area of the triangle AOB is 10

Answer:
44,62, and where is E
Step-by-step explanation:
Part (i)
Angle DBA = 44--------
Reason:
Angle CBA is a right angle (thales theorem), so angle DBA must add to DBC to get 90 degrees. In other words, we solve x+46 = 90 to get x = 44.
============================================================
Part (ii)
Angle DAC = 46--------
Reason:
Both inscribed angles DAC and DBC subtend the same arc (minor arc DC), so the inscribed angles are congruent.
============================================================
Part (iii)
Angle BCE = 74--------
Reason:
Angle BDC is 28 degrees since angle BAC is also 28 degrees (similar reasoning as part ii above). Let y = angle BCD
Focus on triangle BCD. The three interior angles add to 180
B+C+D = 180
46+y+28 = 180
y+74 = 180
y = 180-74
y = 106
Then subtract 180 from this to get the exterior angle BCE
angle BCE = 180-(angle BCD)
angle BCE = 180-y
angle BCE = 74
Or as a shortcut, you could use the remote interior angle theorem
angle BCE = (angle BDC) + (angle DBC)
angle BCE = (28) + (46)
angle BCE = 74

Answer:
c. y = -x + 4
Step-by-step explanation:
Looking at the graph, the trend is decreasing as you move to the right, so you know that the slope has to be negative. Therefore (a) and (d) cannot be the answer since they both have positive slope.
You're only choice left is (b) and (c). (b) can't be the asnwer because averaging out the value at x=0 will give you a value greater than 3, therefore your y-intercept must be some number greater than 3. The only answer choice left is (c).

what is the equation of the line that contains the points (3,5) and (7,9)
Answers
Answer:
y=x+2
Step-by-step explanation:
The required equation of line will be y = x + 2.
It is given that a line contains points (3,5) and (4,9).
We have to find out the equation of the line.
What is the general equation of a line ?
The equation of a line is y = mx + c.
As per the question line contains points ;
(x1,y1) = (3,5) and (x2,y2) = (7,9) .
Using these points, firstly , we need to find the value of m ;
∵ m = ( y2-y1) / (x2-x1)
m = ( 9-5) / (7-3)
m = 4 / 4
m = 1
We now need to find out the value of c.
Since , (7,9) is on the line this meant this meant value of c is 2.
Putting the value of m and c in general equation of line i.e., y= mx + c
y = 1 × x + 2
y= x + 2

If x + 2y = 8, and x - y = 5, what is the value of x?
Answers
Answer:
x = 6
Step-by-step explanation:
Let's solve y for x + 2y = 8.
x + 2y = 8
2y = -x + 8
y = [tex]-\frac{1}{2}[/tex]x + 4.
Let's solve y for x - y = 5.
x - y = 5
y = x - 5
Since both equations have been solved for y, we can combine them together into one!
x - 5 = [tex]-\frac{1}{2}[/tex]x + 4
x [tex]+ \frac{1}{2}[/tex]x = 4 + 5
1.5x = 9
x = 6

Answers
Answer:
A. (-.5, 3)
B. y=-2x+2
C. y=-2x+7
Step-by-step explanation:
A. Midpoint formula, M=[tex]\frac{x_{1 }+x_{2}}{2} + \frac{y_{1 }+y_{2}}{2}[/tex]
B. Find the slope given Δy/Δx which just means change in y over change in x. -2-8/2-(-3) which is -10/2 which reduces to a slope of -2. Then use the point slope equation [tex]y- y_{1}=m(x-x_{1} )[/tex] where you fill in -3 for for x1 and 8 for y1. Solving for y gives you y=-2x+2
C. If a line is parallel to another line then they have the same slope, so the y=-2x part stays the same. What is different, though, is the y intercept. Luckily the y intercept is given in the problem, as the problem says the line passes through 0,7 so we know that this is the intercept. Thus, we know the equation is y=-2x+7
D. I'm not sure on this one, sorry. You can look up slope in ax+by+c=0 form though
