Determine whether the following statement is true or false.
The ordered pairs (8,- 9) and (-9,8) name the same point.
Answers
Hi!
I can help you with joy!
Are these ordered pairs the same? Do they name the same point?
(8, -9) and (-9,8) are our points.
The x-coordinate of one point is 8, and the x-coordinate of the second point is -9.
The y-coordinate of the first point is -9, and the y-coordinate of the second point is 8.
Thus, these 2 ordered pairs do not name the same point.
The statement is false.
I hope this helps!

Z=180°-y
=180°-110°
=70°
X=y
X=110°
Step-by-step explanation:
Solution,
∠IDJ = 70° ( being alternate angle in AB || CD )
∠ IDJ + x = 180° ( being co-interior angle in EF || GH )
or , 70° + x = 180°
or , x = 180° - 70°
x = 110°
Again,
∠BLH = ∠CKG ( Being alternate angle in AB || CD )
y = 110°
Finally ,
z + y = 180° ( Being adjacent supplementary angle )
or , z + 110° = 180°
z = 70°
Thus , x = 110 ° , y = 110 ° and z = 70°
A bird of species A, when diving, can travel six times as fast as a bird of species B top speed. If the total speeds for these
two birds is 259 miles per hour, find the fastest speed of the bird of species A and the fastest speed of the bird of species B.
What is the fastest speed of the bird species B in miles per hour and the fastest speed of the bird of species A in miles per hour
Answers
Answer:
37 mph, 222 mphStep-by-step explanation:
Let the speed of bird of species A is x and speed of B is y.
The equations:
x + y = 259x = 6ySubstitute and solve for y:
6y + y = 2597y = 259y = 259/7y = 37Find x:
x = 6*37 = 222
[tex]x[/tex]will be the speed of species b and [tex]4x[/tex] will be the speed of species a:
[tex]x + 4x = 180[/tex]
[tex]5x = 180[/tex]
[tex]x = \frac{180}{5}[/tex]
[tex]x = 36 \: m/h[/tex]
If species b has a speed of [tex]36 [/tex]m/h, the speed of species a is [tex]4[/tex]times that:
[tex]4 \times 36 = 144 m/h[/tex]
Answer :—
[tex]A = 36 \: m/h [/tex]
[tex]B = 144 \: m/h[/tex]
When three times a number is decreased by 7, the result is 20. What is the number?
The number is?
Answers
Answer:
The number is 9
Step-by-step explanation:
• Let the number be x
[tex]{ \tt{3x - 7 = 20}} \\ [/tex]
» Add 7 to either sides following addition rule of equality:
[tex]{ \tt{(3x - 7){ \red{ + 7}} = 20{ \red{ + 7}}}} \\ { \tt{3x = 27}}[/tex]
» Divide either sides by 27:
[tex]{ \tt{ \frac{3x}{ \blue{3 }} = \frac{27}{ \blue{3}} }} \\ \\ { \tt{x = 9}}[/tex]
3x=27
x=9
number is 9
