During a science experiment, Daniel noted the starting temperature of a -4°F. At the end of the experiment, the change in temperature was -5°F. What was the final temperature?
A.-1 B.1 C.9 D.-9
Answer:
D.) - 9
Step-by-step explanation:
Given the following :
Temperature at the start of experiment = - 4°F
At the end of experiment, change in temperature = - 5°F
This means between the temperature at the start of the experiment was - 4°F and during the cause of the experiment, there was a change in temperature of - 5°F.
Hence, the final temperature is the sum of the initial temperature and and the temperature change recorded.
Initial temperature + temperature change
-4°F + (-5°F)
- 4°F - 5°F = - 9°F
Hence, final temperature = - 9°F
Answer:
The answer is 9
Given the following :
Temperature at the start of experiment = - 4°F
At the end of experiment, change in temperature = - 5°F
This means between the temperature at the start of the experiment was - 4°F and during the cause of the experiment, there was a change in temperature of - 5°F.
Hence, the final temperature is the sum of the initial temperature and and the temperature change recorded.
Initial temperature + temperature change
-4°F + (-5°F)
- 4°F - 5°F = - 9°F
Hence, final temperature = - 9°F

The answer is H. II and III only.
Step-by-step explanation:
A simple way to tell if a relation is a function is by taking a look at the X value, which is on the left. If the X value repeats again (ex: (0,1) (0,2) or (5,3 (5,7)) it is not a function. However, the Y value is allowed to repeat.
if EF bisects CD, CG =5x-1, GD = 7x-13, EF = 6x-4, and GF =13, find EG
Greetings from Brasil....
As stated in the statement of the question, EF is a bisector of CD, so point G is the median point of CD, so CG = GD
5X - 1 = 7X - 13
X = 6
EF = EG + GF
6X - 4 = EG + 13 x = 6, so
6·6 - 4 = EG + 13
EG = 19(see attachment)
A line segment is also a line but the line with finite length and having fixed endpoints. The length of the line segment EG is 19 unit.
What is a line?A line is a one-dimensional shape that is straight, has no thickness, and extends in both directions indefinitely.
Given that EF bisects CD at point G, therefore, the line segment CD will be divided into two equal parts, CG and GD. Therefore, we can write,
CG = GD
5x - 1 = 7x - 13
-1 + 13 = 7x - 5x
12 = 2x
x = 12/2
x = 6
Further, the length of segment EG will be,
EG = EF - GF
= 6x - 4 - (13)
= 6x - 4 - 13
= 6x - 17
= 6(6) - 17
= 36 - 17
= 19
Hence, the length of the line segment EG is 19 unit.

The base of a triangle is 2 feet less than its height. Its area is 12 square feet. Find its base and height.
Answer:
Height of the triangle is 6 feet and base of the triangle is 4 feet.
Step-by-step explanation:
Area of a triangle is given by the formula,
Area = [tex]\frac{1}{2}(\text{Base})(\text{Height})[/tex]
Let the height of triangle = h feet
Since, base of the triangle is 2 feet less than its height then base of the triangle = (h - 2) feet
Area = [tex]\frac{1}{2}h(h-2)[/tex]
[tex]12=\frac{1}{2}h(h-2)[/tex]
h² - 2h - 24 = 0
h² - 6h + 4h - 24 = 0
h(h - 6) + 4(h - 6) = 0
(h + 4)(h - 6) = 0
h = -4, 6 feet
Since height of the triangle can not be negative, therefore, height of the triangle = 6 feet.
And base of the triangle = (h - 2) = 6 - 2
= 4 feet
Height of the triangle is 6 feet and base of the triangle is 4 feet.

Find x when y=6 in the literal equation 5x+4y=39
A. 12.6
B. 15
C. 2.25
D. 3
Answer:
y=6
then,
5x+4y=39---> plug y in to the function
5x+4(6)=39
5x+ 24=39
5x= 39-24
5x= 15
x= 15/5
x= 3
So, the value of x when y=6 in that function is 3 (D)

Solve 2x + 3y = 11 and 2x - 4y = -24 and hence find the value of 'm' for which y=mx+3.
Answer:
m=-1
Step-by-step explanation:
2x+3y=11............. (eqn 1)
2x-4y=-24...........(eqn 2)
Subtract eqn 1 from eqn 2
7y=35
y=5
Substitute for y in eqn 1
2x+3(5)=11
2x+15=11
2x=11-15
2x=-4
x=-2
y=mx+3
5=-2m+3
5-3=-2m
2=-2m
m=-1
Answer:Here,
2x+3y=11..........(i)2x-4y= -24......... (ii)Subtracting (ii) from (i),we get
2x+3y=11
- 2x+4y=24
___________
7y =35
y=5
Substituting y = 5 in (i) we get
2x+3×5=11
or,2x +15 =11
or,2x = 11- 15
or,x= -2
Now,
We know,y=mx+c
5=m ×(-2) +3
or,2=m×(-2)
or,2/-2 =m
m= -1

Anyone down to help? 12pts for PRE-ALGEBRA question Use the information in the table for 2–4.
Answer:
See attached image
Step-by-step explanation:
If the number of blueberries is the x value, and number of calories is the y value, then we can create the ordered pairs (5,4) (10,8) (15,12) based on the data in the table.
Plotting these on the graph is simple - just go to the x value then the y value and plot where these lines meet.
The slope of a line is always the rise over run.
Every time our x increases by 5, our y increases by 4. The rise is 4, and run is 5, so the slope is [tex]\frac{4}{5}[/tex]
