Step-by-step explanation:
Given
[tex]x^2 - 12x = 21[/tex]
Required
Make a perfect square
First, get the coefficient (k) of x
[tex]k = -12[/tex]
Divide by 2
[tex]\frac{k}{2} = \frac{-12}{2}[/tex]
[tex]\frac{k}{2} = -6[/tex]
Square this result:
[tex](\frac{k}{2})^2 = (-6)^2[/tex]
[tex](\frac{k}{2})^2 = 36[/tex]
Hence, 36 when added to the left-hand side makes it a perfect square trinomial

2. A line has an x-intercept of 2 and a y-intercept of 5. What is the slope
of the line?
Answers
Answer:
-5/2
Step-by-step explanation:
Use slope formula:
Given 2 points (x1, y1) and (x2, y2) Slope is
y2-y1/x2-x1
The x intercept is 2, the point would be (2,0)
The y intercept is 5, the point would be (0,5)
So you can do (5-0)/(0-2) which is 5/-2 which then would be -5/2
-5/2
Explanation:
We are given two points from the problem: (2,0) and (0,5). Using these two points, we can calculate the slope using the formula y2-y1/x2-x1 by plugging in points (x1,y1) and (x2,y2).
y2-y1/x2-x1
0-5/2-0
-5/2
Therefore, the slope of the line is -5/2.

Find the probability P(E or F) if E and F are mutually exclusive, P(E)=0.41 and P(F) = 0.47
P(E or F) =
Answers
Answer:
P(E or F)=P(E)+P(F)=0.41+0.47=0.88
As per the probability of an event, the probability P(E or F) is 0.88, when E and F are mutually exclusive.
What is probability of an event?"Probability is simply how likely something is to happen. Whenever we're unsure about the outcome of an event, we can talk about the probabilities of certain outcomes how likely they are.
Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur, or how likely it is that a proposition is true. The probability of an event is a number between 0 and 1, where, roughly speaking, 0 indicates impossibility of the event and 1 indicates certainty. "
Given, the probability of the event E is P(E) = 0.41
The probability of the event F is P(F) = 0.47
Now, the probability P(E or F) is
= P(E) + P(F)
= 0.41 + 0.47
= 0.88
Therefore, P(E or F) = 0.88

Step-by-step explanation:

slope (m) = rise/run = (2 - -10) / (17 - 15) = 12/2 = 6
2-(-10), or 2+10 since you’re subtracting a negative and they cancel out is equal to 12. Now take your two x points, 15 and 17. 17-15 is equal to 2. Take 12 and divide it by the 2, which is then 6. Hope this helps.
a primary school has a running track.
it has two straights of 50 metres.
also there are two bends that are semicircles with diamter 30 metres
work out the distance around the running track
Answers
Answer:
Distance around the track = 194.3 metres.
Step-by-step explanation:
Given: The two straight sides are of the track are 50 metres each
Diameter of each bend = 30 metres
Thus;
radius of the bends = [tex]\frac{diameter}{2}[/tex]
= [tex]\frac{30}{2}[/tex]
= 15 metres
So that,
length of the semicircular bend = [tex]\frac{1}{2}[/tex] x 2[tex]\pi[/tex]r
= [tex]\pi[/tex]r = [tex]\frac{22}{7}[/tex] x 15
= 47.143
length of each semicircular bend is 47.14 metres.
Distance around the track = addition of the length of each straight sides + addition of the length of the bends
= 50 + 50 + 47.14 + 47.14
= 194.28
Therefore,
Distance around the track = 194.3 metres.

Amber has been working very hard and finally got a salary increase of 100%. She was earning $200 per week. How much is she earning now? *
Answers
Answer:
$400
Step-by-step explanation:
Given that:
Earnings per week for Amber = $200
Total increase in the salary as per Amber's hard work = 100%
To find:
Earnings of Amber now?
Solution:
We are given the initial salary and its percentage increase.
We have to find the increased value of salary.
Increase in the salary = 100% of $200
[tex]\Rightarrow \dfrac{100}{100}\times \$200\\\Rightarrow \bold{\$200}[/tex]
Amber's Current salary = Initial salary + Increase in the salary
Putting the values of the initial salary and increase in the salary:
Amber's Current salary = $200 + $200 = $400

Here are his meter readings.
New reading:
Old reading
6538 units
6245 units
a)
Use subtraction to calculate the number of units used.
b)
Calculate the cost of the number of units used.
Answers
Answer:
a) 293 units
b) £57.95
Step-by-step explanation:
a)
New reading: 6538 units
Old reading : 6245 units
The amount use is the difference between the two readings.
6538 - 6245 = 293
Answer: 293 units
b)
293 is the same as 200 units plus another 93 units.
The first 200 units are charged at 22p per unit
Cost of the first 200 units: 200 units * 22p/unit = 4400p
Remaining units are charged at 15p per unit
Cost of the additional 93 units: 93 units * 15p/unit = 1395p
Total charge: 4400p + 1395p = 5795p = £57.95
Answer: £57.95
Trapezoid ABCD is shown on the graph. If the trapezoid is rotated 90 degrees
counterclockwise about the origin and the resulting image is translated 6
units left, what are the coordinates of C"?
Answers
Answer:
The coordinates of C" are (-7, 4)
Step-by-step explanation:
If the point (x, y) rotated about the origin by angle 90° counterclockwise, then its image is (-y, x)If the point (x, y) translated horizontally to the left by h units, then its image is (x - h, y)From the given figure
∵ ABCD is a trapezoid
∵ The coordinates of the ponit C are (4, 1)
∴ x = 4 and y = 1
∵ The trapezoid is rotated 90 degrees counterclockwise about the origin
→ By using the 1st rule above, change the sigh of y and switch them
∴ C' = (-y, x)
∴ C' = (-1, 4)
∵ The resulting image is translated 6 units left
→ By using the 2nd rule above subtract the x-coordinate by 6
∴ C" = (x - h, y)
∵ h = 6
∵ x = -1 and y = 4
∴ C" = (-1 - 6, 4)
∴ C" = (-7, 4)
∴ The coordinates of C" are (-7, 4)

Write the equation of the line that passes thought the points (0,4) and (-9, -3).
Put your answer in fully reduced point-slope form, unless it is a vertical or horizontal line.
Answers
Answer:
The equation of the straight line in point-slope form
[tex]y - 4 = \frac{7}{9} (x-0)[/tex]
The equation of the straight line
7x -9y +36 =0
Step-by-step explanation:
Step(i):-
Given that the points (0,4) and (-9,-3)
The slope of the line
[tex]m = \frac{y_{2} - y_{1} }{x_{2}- x_{1} } = \frac{-3-4}{-9-0} = \frac{7}{9}[/tex]
Step(ii):-
Equation of the straight line passing through the point (0,4) and having slope m = 7/9
[tex]y - y_{1} = m (x-x_{1} )[/tex]
[tex]y - 4 = \frac{7}{9} (x-0)[/tex]
9 y - 36 = 7x
9y = 7x + 36
[tex]y = \frac{7x}{9} +\frac{36}{9}[/tex]
Slope - intercept form
[tex]y = \frac{7x}{9} +4[/tex]
Final answer:-
The equation of the straight line in point-slope form
[tex]y - 4 = \frac{7}{9} (x-0)[/tex]
The equation of the straight line
7x -9y +36 =0
