Answer:
(0,6) and (1.2 , 0)
Step-by-step explanation:
5x + y = 6
if we take x=0
5(0) + y = 6
y = 6 ; so, one of the solution is (0,6)
if we take y=0
5x + (0) = 6
5x = 6
x = 6/5 = 1.2 ; so, the other solution is (1.2 , 0)
But basically, you can find other solutions of the equation if you do this:
5x + y = 6
5x = (6 - y)
x = (6 - y) / 5 ; so if you use whatever number of y, you will find the rigth solution for x.
and you can do the opposite too:
5x + y = 6
y = 6 -5x ; with this, you can use whatever number of x, and find the right y.
I hope this helps you!!!

C. Two motorcycles start at the same point. One travels 15 km due north and stops while the other travels 32 km due west
and stops. Which value is closest to the distance between the motorcycles when they are both stopped?
A. 28.3 km
B. 47.0 km
C. 35.3 km
D. 21.9 km
The Distance between the motorcycles is 35.3 km
Pythagoras theorem shows the relationship between sides in a right angled triangle.
The distance moved north, distance moved west and the distance between the motorcycles form a right angled triangle.
distance between the motorcycles² = distance moved north² + distance moved north²
Distance between the motorcycles² = 15² + 32²
Distance between the motorcycles² = 1249
Distance between the motorcycles = 35.3 km
Hence the Distance between the motorcycles is 35.3 km

substitution of a,b,c in this equation
Answer:
2, 1 and -3
Step-by-step explanation:
Given the quadratic expression
x^2+2x = 3
Write in standard format
x^2+2x-3 = 0
Get the value of a, b and c
The standard form is ax^2+bx+c = 0
ax^2 = x^2
a = 1
bx = 2x
b = 2
c = -3
Substitute into the general formula
x = -b±√b²-4ac/2a
x = -2±√(2)² - 4(1)(-3)/2(1)
The correct values are the values in bold format

Find 25% of 152:
Find 75% of 152:
Answer:
76
38
114
Step-by-step explanation:
50% of 152
= ( 50 / 100 ) x 152
= ( 1 / 2 ) x 152
= 152 / 2
= 76
25% of 152
= ( 25 / 100 ) x 152
= ( 1 / 4 ) x 152
= 152 / 4
= 38
75% of 152
= ( 75 / 100 ) x 152
= ( 3 / 4 ) x 152
= ( 3 x 152 ) / 4
= 3 x 38
= 114

Median: 69
First Quartile: 65.5
Third Quartile: 73
Interquartile Range: 7.5
Step-by-step explanation:
First, put all of the numbers in order.
63, 64, 67, 68, 70, 72, 74, 76.
Median
For the median, it is the center of the data set.
To find the median of this data set, add 68, and 70, then divide by 2.
The Median is 69.
First Quartile
To find the first quartile, find the range below the median (63-68).
Find the median of that range.
Add 64 & 67 together, then divide by 2.
The first quartile = 65.5
Third Quartile
Do the same as the first quartile, but do it with the range above the median (70-76).
Add 72 & 74 together, then divide by 2.
The third quartile = 73.
Interquartile Range
Now, take the first and third quartile, and subtract.
[tex]73-65.5=IR[/tex]
[tex]7.5 = IR[/tex]
The interquartile range is 7.5.
The brick fire ring measures sixteen feet across the center. What is the circumference of the fire ring to
the nearest tenth?
Plan:
Calculations:
Answer:
50.3 ft
Step-by-step explanation:
circumference = 2nr
the diameter is the straight line that passes through the centre of a circle and touches the two edges of the circle.
A radius is half of the diameter
radius = 16/2 = 8
2 x 22/7 x 8 = 50.3ft
the tenth is the first number after the decimal place. To convert to the nearest tenth, look at the number after the tenth (the hundredth). If the number is greater or equal to 5, add 1 to the tenth figure. If this is not the case, add zero

if an area of the rectangle below is 39 square feet, sides are x-2 and x+8 find the area of x
Answer:
x = 5.
Step-by-step explanation:
The area of a rectangle can be determined by the following formula.
A = l ⋅ w
l stands for length or the longer side.
w stands for width or the shorter side.
Now, we can plug the values we are given into the equation.
A = ( x − 2 ) ⋅ ( x + 8 )
The easiest way to multiply is to follow the acronym FOIL , which stands for First Outside Inside Last, and dictates the order in which you multiply these terms.
A = x 2 + 8 x − 2 x −16 = x 2 + 6 x − 16
Now, we can plug in the given value for the area.
39 = x 2 + 6 x − 16
Next, we simplify by moving all terms to one side and factor the equation.
0 = x 2 + 6 x − 55
Finally, we factor the equation. This means we reverse-FOIL, trying to determine the two things that we multiplied together.
0= ( x − 5 ) ⋅ ( x + 11 )
If the equation ultimately equals zero, either ( x − 5 ) or ( x + 11 ) or both equal zero. Therefore, we set each equal to zero to find the value of
x .
x − 5 = 0 x = 5 x + 11 = 0
x = − 11
Since x is a length, we know it cannot be negative. Thus, we can conclude that it equals 5.

Refer to the accompanying data set and use the 30 screw lengths to construct a frequency distribution. Begin with a lower class limit of 3.470 in., and use a class width of 0.010 in. The screws were labeled as having a length of 3 1/2 in
Answer:
Answer:
A) Total frequency = 30
B) Yes, the distribution is consistent with the label because the frequencies are greatest when the lengths are closest to the labeled size of 1/2 inches which is 0.5 inches.
Step-by-step explanation:
Since the class limit width is 0.010 from the question, we arrive at;
Class Limits Frequency
Length(Inches)
0.470 - 0.479 3
0.480 - 0. 489 5
0.490 - 0.499 9
0.500 - 0.509 12
0.510 - 0.519 1
Following is the frequency distribution table:
How to build a frequency table?The lower limit is given as 3.470 inches.

In simplest form.
more than one pair, use the "or" button. Give the answer
In simplest form
Answer:
11 and -4
Step-by-step explanation:
Let the required two numbers be x and y
If the sum of two numbers is 7, then
x + y = 7 .. 1
If the difference of their squares is 105, then;
x² - y² = 105 ...2
From 1;
x = 7 - y... 3
Substitute 3 into 2;
(7-y)² - y² = 105
Expand
49-14y+y² -y² = 105
49-14y = 105
-14y = 105 - 49
-14y = 56
y = -56/14
y = -4
Substitute y = -4 into 3
x = 7 - y... 3
x = 7 - (-4)
x = 7+4
x = 11
Hence the numbers are 11 and -4
