Answer:
15
Step-by-step explanation:
Think about multiplying any two rational numbers. Based on this activity and your previous work, write a set of rules for finding the sign of the product based on the sign of the two numbers being multiplied.
Answer:
Positive (+) * positive (+) = +
Negative (-) * negative - = +
Negative (-) * positive (+) = -
Positive (+) * negative (-) = +
Step-by-step explanation:
How result of the product of two numbers are affected by the sign on each number being multiplied :
Signs on number values may be positive (+) or negative (-)
The rules goes thus :
Positive (+) * positive (+) = +
Negative (-) * negative - = +
Negative (-) * positive (+) = -
Positive (+) * negative (-) = +
Therefore for any tow rational numbers, the sin of their product will follow the rules above.
prove that 5root7 is i
rrational
Answer:
See Explanation
Step-by-step explanation:
Let us assume that [tex] 5\sqrt 7[/tex] is a rational.
Therefore, it can be expressed in the form of [tex] \frac{p}{q}[/tex], where p and q are integers.
[tex] \implies 5\sqrt 7=\frac{p}{q}[/tex]
[tex] \implies \sqrt 7=\frac{p}{5q}[/tex]
[tex] \because [/tex] p and q are integers.
[tex] \therefore \frac{p}{5q}[/tex] is a rational number.
[tex] \implies \sqrt 7[/tex] is rational ([tex] \because [/tex] quotient of a rational number is rational)
But, it contradicts the fact that [tex]\sqrt 7[/tex]is irrational.
So, [tex]5\sqrt 7[/tex] is also irrational, because the product of rational and irrational is irrational.
This contradiction is arising out because of our wrong assumption that [tex] 5\sqrt 7[/tex] is rational.
Hence, [tex] 5\sqrt 7[/tex] is irrational.

Thank you!
Answer:
Step-by-step explanation:
square- 48*32=1536
triangle- .5*12*48= 288
Answer:
ALI = 288 in²AIEN = 1536 in²ALIEN = 1824 in²Steps:
ALI = 48×12/2 = 48×6 = 288 in²
AIEN = 48×32 = 1536 in²
ALIEN = ALI + AIEN
ALIEN = 288 + 1536
ALIEN = 1824 in²

The rational numbers include all the integers, plus all fractions, or terminating decimals and repeating decimals. ... All natural numbers, whole numbers, and integers are rationals, but not all rational numbers are natural numbers, whole numbers, or integers.
So if the following system of equations by substitution.
7x+2y= -13
-3x-8y= -23
A. (-3,1)
B. (-3,4)
C. (1,3)
D. (1,1)
Step-by-step explanation:
Option B is correct.
I'm sure (-3 , 4)
Answer:
x=-3, y=4. (-3, 4). B)
Step-by-step explanation:
7x+2y=-13
-3x-8y=-23
-------------------
4(7x+2y)=4(-13)
-3x-8y=-23
---------------------
28x+8y=-52
-3x-8y=-23
-------------------
25x=-75
x=-75/25
x=-3
7(-3)+2y=-13
-21+2y=-13
2y=-13-(-21)
2y=-13+21
2y=8
y=8/2

Point B has coordinates (2,1). The x-coordinate of point A is -10. The distance between point A and point B is 15 units. What are the possible coordinates of point A?
Answer:
(-10, 10) or (-10, -10)
Step-by-step explanation:
[tex]d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2[/tex]
[tex]15 = \sqrt{(-10 - 1)^2 + (y_2 -2 )^2}[/tex]
[tex]15 = \sqrt{121 + 2y + y^2 + 4}[/tex]
[tex](15)^{2} =( \sqrt{121 + 2y + y^2 + 4})^{2}[/tex]
[tex]225 = 121 + 2y + y^2 + 4[/tex]
[tex]225 = 125 + 2y + y^2[/tex]
[tex]0 = -100 + 2y + y^2[/tex]
[tex]0 = (y + 10)(y - 10)[/tex]
Becky and Keith run for exactly 20 minutes on a treadmill keith's treadmill said he had run 10,000 ft Becky's treadmill had said she had run 2 miles who ran farther and how much farther?
Answer:
Becky ran farther and farther by 560 ft.
Step-by-step explanation:
1 mile = 5280 ft
Becky: 2 * 5280 = 10560 ft
Keith: 10000 ft
10560 ft > 10000 ft, so Becky ran more distance than Keith.
10560 - 10000 = 560 ft, so Becky ran 560 ft more than Keith.

Find the distance from the point P(4,1) to the line segment joining the points Q(1,-8) and R(-4,2). Show your steps.
Answer:
7,8
Step-by-step explanation:
Distance Formula:
The distance between two points is the length of the path connecting them. The shortest path distance is a straight line. In a 2 dimensional plane, the distance between points (X1, Y1) and (X2, Y2) is given by the Pythagorean theorem:
d=(x2−x1)2+(y2−y1)2−−−−−−−−−−−−−−−−−−√
Calculate Distance
To calculate the distance between 2 points, (X1, Y1) and (X2, Y2), for example, (5, 6) and (-7,11), we plug our values into the distance formula:
d=(−7−5)2+(11−6)2−−−−−−−−−−−−−−−−−√
combining terms inside parentheses we get:
d=(−12)2+(5)2−−−−−−−−−−−√
squaring both terms we get,
d=144+25−−−−−−−√
adding the 2 results,
d=169−−−√
finally,
d=13
The two lines represented by the equations below are graphed on a coordinate plane. Which statement best describes
the two lines?
2x + y = 12
y-2 = 3(x - 2)
1) parallel
2) perpendicular
3) the same line
4) neither parallel nor perpendicular
Answer:
4
Step-by-step explanation:
2x+y=12
y=-2x+12
y-2=3(x-2)
If it’s parallel to each other: the slope has to be the same.
If is perpendicular to each other: the slope should be the reciprocal to each other.
The first equation has a slope of -2
The second has a slope of 3
Neither the condition meet. So the answer is 4

Answer:
R = 90
Step-by-step explanation:
Triangles will always equal 180 degrees. If you add 61 + 29 = 90. If two of the three angles already equal 90 degrees, then you would subtract 180 - 90. Therefore, the remaining angle would have to be 90 degrees.

What is the value of x?
26°
to
X =
= [?]
Answer:
x = 154°
Step-by-step explanation:
The central angle and the angle between the tangents are supplementary, so
x + 26° = 180° ( subtract 26° from both sides )
x = 154°

A system of equations is shown.
y = 2x – 7
y = -x + 5
What is the solution to the system of equations?
Answer:
x = 4
Step-by-step explanation:
Eliminate y by setting the first equation equal to the second:
2x - 7 = -x + 5
Combining like terms, we get:
3x = 12, so that x must be 4.
