The height of plant B growing at a rate of 3.33 centimeters per week should have a height of 19.98 cms.
What are lines and their slopes?We know lines have various types of equations, the general type is
Ax + By + c = 0, and equation of a line in slope-intercept form is y = mx + b.
Where slope = m and b = y-intercept.
the slope is the rate of change of the y-axis with respect to the x-axis and the y-intercept is the (0,b) where the line intersects the y-axis at x = 0.
First we need two points (x, y) to obtain the slope.
Assuming height to be 'y' and weeks to be 'x'.
Therefore, (0, 0) and (3, 10) are the two points.
Slope(m) = (10 0)/(3 - 0).
Slope(m) = 10/3.
Slope(m) = 3.33
Now, To obtain the y-intercept.
10 = 3(3.33) + b
b = 0.01 Or neglegible.
Therefore y = 3.3x.
Now, In the 6th week, the height of plant B will be,
y = 3.33(6).
y = 19.98 or 20 cm.

f(-7) = -4
Answer:
f(-7)=-4
Step-by-step explanation:
If you look at the x, in this case -7, and follow it down to where it stops on the parabola, you will see that it's y value is -4.

What is the image of the point (7,-5) after a rotation of 270° counterclockwise
about the origin?
Answer:
(-5, -7)
Step-by-step explanation:
if you rotate the point by 270 degrees counterclockwise, you get (5,-7) and I'm guessing image is another way to say reflection so after it is reflected then the point would be (-5,-7)

7 + 5x = 2x + 25
step by step pls:(
Answer:
x = 6
Step-by-step explanation:
7 + 5x = 2x + 25
first subtract 7 from both sides to isolate 5x on the left
5x = 2x + 18
then subtract 2x from both sides to isolate all of the x terms to one side
3x = 18
then divide 18 by 3 to solve for x
x = 6

You have 5814 meters of rope you need to cut into 27 sections how many 27 meters secton of rope will you be able to create and how much rope will be left over as waste
Answer:
215 sections of rope that measure 27 meters in length, and you also have 9 meters of rope left
Step-by-step explanation:
we have 5,814 meters of rope and we are told to calculate the number of 27 meters sections that we can cut:
you have to divide 5,814 meters by 27 meters = 215.333
that means that you have 215 sections of rope that measure 27 meters in length, and you also have 9 meters of rope left (0.333 x 27 = 9)
Find the inequality represented by the graph
Answer:
y ≥ 1/2xStep-by-step explanation:
Given the following inequality, we know that y must be greater than or equal to x because the line is not dashed, and is shaded above the line.
Now to find the equation just pretend that this is just a normal linear equation, and solve for the equation.
So since the y intercept is 0, and there is a rise of 1 for a run of 2 or 1 unit up every two units to the right, the corresponding linear equation is y = 1/2x.
Now since this is an inequality where y is greater than or equal to x.
y = 1/2x → y ≥ 1/2x
In a multiple choice examination of 20 questions, four marks are given for each correct answers and one mark is deducted for each wrong answer. There is no penalty for not attempting a question. a candidate attempts "a" questions and get "c" correct. Write down, and simplify, an expression for the candidate's total mark in terms of "a" and "c".
Answer:
Total Mark = 5c - a
Step-by-step explanation:
Total Mark = 4c - (a - c) = 5c - a
Marks for correct questions = 4c
Marks deducted for incorrect questions = a - c

A college information pamphlet provides some statistics about the students and the professors to help high school seniors decide if they want to attend the college. The pamphlet lists the ratio of students to professors as 18 to 1. If there are 702 students at the college, how many professors are there?
Answer:
39
Step-by-step explanation:
Setting up your problem and solving:
In the question it says the ratio is students to professors right? So 18 to 1.
Write that down: Students to Professors is 18 to 1.
We know that there are 702 students in that college correct?
Write that down: 702 students in the college
We are trying to find how many professors there are so...let's do that.
Number 1:
Set your equation: have your fraction bar and equal sign like this: --- = ---
On the top, we have 1 so... 1/? = ?/?
On the other top we have the x...: 1/? = x/?
Why? Because we do not know the total of professors there are so that is X.
We put the number 1 on the other side because we know that there is only 1 out of 18 professors to students.
Number 2:
On the bottom, we will have 18...: 1/18 = x/?
On the other bottom we have 702...: 1/18 = x/702
Why? Because we know that there is a total number of 18 to 1 students on the ratio and a real total of 702 students.
Number 3.
Now you have your equation set up: 1/18 = x/702
The next step is yours: cross multiple, divide on the bottom or top or find the comparison.
I'm going to divide by the bottom okay? so.. 18/702
Set that up.
(702/18)
702/18 is 39!
SO in the end there is a total of 39 professors!
'x=39'

77th term for -10,-8,-6
9514 1404 393
Answer:
142
Step-by-step explanation:
The first term of this arithmetic sequence is -10. The common difference is -8-(-10) = 2. The n-th term is ...
an = a1 +d(n -1)
an = -10 +2(n -1) = 2n -12
Then the 77th term is ...
a77 = 2(77) -12 = 154 -12
a77 = 142
The 77th term is 142.

Which simplified equation is equivalent to the equation shown below? 4x + -3 -9 +4x=6
Answer:
x + x = 4.5 or x = 2.25 is the answer or the value of x.
Step-by-step explanation:
4x + -3 -9 +4x=6
4x + 3 + 9 + 4x=6 + 3 + 9
4x + 4x = 18
4x/4 + 4x/4 = 18/4
x + x = 4.5
x = 2.25
