Which point on the coordinate plane below is (-9, 3)?
Point D
Point C
Point B
Point A
Answers
Answer:B
Step-by-step explanation: x is -9 and y is 3
Since it’s negative you’d go left by 9 blocks and the y is positive so you go up 3
Answer:
The answer is point B
Step-by-step explanation:
I know this because (-9, 3) seems to be located in quadrant 2 because in quadrant 2 along the x-axis it is negative and along the y-axis it is positive. So, when l look in quadrant 2 there seems to be only one point, point B, which if you look at it is 9 units to the left and 3 units upward.

One number is seven more than six times another number. If the sum of the numbers is 21, find the numbers
Answers
Answer:the two numbers are 2 and 19
Step-by-step explanation:
Let one of the numbers be x
and the second be 7+ 6x
so that the sum of the two numbers which totals 21 be expressed as
x + (7+ 6x) = 21
x+ 7+6x= 21
7 + 7x = 21
7x= 14
x= 14/7 = 2
one of the numbers = 2
the other number given as
7+ 6x = 7+ 6 x 2= 7+12= 19
The numbers are 2 and 19 .
The numbers as described in the question are; 2 and 19
Solving word problemsFrom the given problem statements;
The first number = y
The second number = x
Hence, y = (7 + 6x)
Their sum is therefore;
x + 7 = 6x = 217x = 14x = 2Hence, the second number is; 7 + 6x = 7 + 6(2);
y = 19Read more on word problems;

Step-by-step explanation:
Use the Pythagorean Theorem to figure out which triangle is NOT a right triangle. Square each leg and add them together. Then, square the hypotenuse (longest side). If the sums are equal, then the triangle IS a right triangle.
Pythagorean Theorem:
a(a) + b(b) = c(c) ; a squared plus b squared equals c squared
6(6) + 24(24) =? 26(26) ; leg a =6, leg b=24, hypotenuse=26
36 + 576 =? 676 ; simplify

Which type of climate change is most likely to lead to mass extinction in which vast numbers of species of all kinds die off? A.) A gradual change in precipitation
B.) A gradual warming
C.) A gradual cooling
D.) A very rapid change
Answers
A very rapid climate change is most likely to lead to mass extinction in which vast numbers of species of all kinds die off.
What is ECOLOGICAL SUCCESSION?An ecosystem can change its structure and composition over a particular period. This term is called ECOLOGICAL SUCCESSION.
Succession refers to the gradual change that occurs in a community over time. Succession is of two types; primary and secondary succession.
Climate change and succession are causes of change in the ocean ecosystem. Hence, the succession represents the gradual change that occurs in the structural composition of the ocean ecosystem over time.
The risk of future extinction through rapid global warming is primarily expected to occur by the interaction between the climates to which organisms are adapted in their current range and the future distribution of those climates.
Thus the correct option is D.
A very rapid climate change is most likely to lead to mass extinction in which vast numbers of species of all kinds die off.

A line of best fit predicts that when x equals 29, y will equal 32.75, but y actually equals 32. What is the residual in this case
Answers
Answer:
The residual is 0.75
Step-by-step explanation:
Recall that the residual is the VERTICAL distance between the y-value of the data point and the y-value of the predicted line. This distance can be calculated using the absolute value of the difference between these y-values.
Therefore, in our case the residual is: |32 - 32.75| = |-0.75| = 0.75

What does b stand for 11.3 > b/4.3
Answers
Answer:
b = 45.69
Step-by-step explanation:
5 x 5 = 25
25 x 2 & and a half = 45.69
In the inequality expression "11.3 > b/4.3," the variable "b" represents an unknown numerical value.
In the inequality 11.3 > b/4.3, b is the variable.
The inequality is stating that 11.3 is greater than the result of dividing "b" by 4.3.
The purpose of the inequality is to compare the value of 11.3 with the value of "b/4.3" and determine if 11.3 is greater or not.
The variable "b" can take any value that satisfies the inequality.
Hence, in the inequality b stands for unknown value or variable.
