Find the midpoint of the segment with the given endpoints.
(8,7) and (-6,9)
Solve for y.
8+4y= -8
Answer:
-4
Step-by-step explanation:
8+4y= -8
4y= -8 -8
4y= -16
divide both sides by the coeffient of the variable. in this case divide both sides by 4
y=-4
Answer:
y = -4
Step-by-step explanation:
8+4y= -8
4y = -8 -8
4y = -16
y = (-16) ÷ 4
y = -4

Consider the expression 5 (y-7). Which of the following correctly expresses this expression?
Answer:
5y-35
Step-by-step explanation:
since we don't know what y is you have to multiply y and 7 by 5 and you'd get 5y and 35 and then just add the subtraction and bam there's your answer

\small \angle L and \small \angle M are supplementary, \small m\angle L=12x+45 and \small m\angle M=18x-30. Determine the measure of each angle. \small m\angle L= degrees \small m\angle M= degrees
Answer:
[tex]L = 111[/tex]
[tex]M = 69[/tex]
Step-by-step explanation:
Given
[tex]L = 12x + 45[/tex]
[tex]M = 18x - 30[/tex]
Required
Determine L and M
Since both angles are supplementary;
[tex]L + M = 180[/tex]
Substitute values for L and M
[tex]12x + 45 + 18x - 30 = 180[/tex]
Collect Like Terms
[tex]12x + 18x= 180 - 45 + 30[/tex]
[tex]30x= 165[/tex]
Divide both sides by 30
[tex]x = \frac{165}{30}[/tex]
[tex]x = 5.5[/tex]
Substitute 5.5 for x in [tex]L = 12x + 45[/tex] and [tex]M = 18x - 30[/tex]
[tex]L = 12 * 5.5 + 45[/tex]
[tex]L = 111[/tex]
[tex]M = 18 * 5.5 - 30[/tex]
[tex]M = 69[/tex]

Answer: for part c the gas would not remain a liquid.
Step-by-step explanation: Because as stated, the tempature dropped to -49 degrees farhenheit, and for instance, oxygen, a gas, becomes a liquid if you cool it down to - 297 degrees Fahrenheit (really, REALLY cold) and if you cool it down further to -362 degrees Fahrenheit it becomes a solid, so therefore it definetly couldnt stay a liquid if the temp raised so high. it would seconense back.
i do not know if this is correct but i did try so i am deeply sorry if this fails.

Answer:
first it's adding 4 then it starts adding 8
Step-by-step explanation:
Answer:
If your data represents the following X, Y coordinates (11, 2), (15, 10), and (19, 18) then the slope can be calculate
X = 11 15 19
Y = 2 10 18
m = (y2 -y1)/(x2 - x1)
m = (10 - 2)/(15 - 11)
M = 8/4 = 2

11. STEM To convert a temperature in degrees Celsius to degrees
Fahrenheit, multiply the Celsius temperature by 9/5 and then add 32°. Is a
temperature in degrees Celsius proportional to its equivalent temperature in
degrees Fahrenheit?
Degrees Celsius
0

20
30
Degrees Fahrenheit
132
Answer:
no
Step-by-step explanation:
Whenever a linear equation is something other than
y = kx
the relation is not proportional.
__
Here, you have ...
y = (9/5)x +32
The added constant ensures the relation is not proportional.

Shellys old living room had a length that was twice its width. When she moved, her new living room was 2 feet longer and 4 feet wider that her old one. If w represents the width of her old living room write the expression used to represent the difference in the area of her old living room and her new living room.
Answer:
10w+6 is the difference between the two areas
Step-by-step explanation:
for the old room:
l=2w
wich mean
Area_old=l*w=2w*w=2w²
for the new room:
L=l+2 since l=2w => L=2w+2
W=w+4
so
Area_new=L*W=(w+4)*(2w+2)= 2w² +10w+6
the difference is :
Area_new - Area_old= 10w+6

The two triangles are similar. There are two possible values of x. Work out each of these values. State both assumptions you make in your working. You must state which two triangles you are assuming to be similar.
Answer:
ΔABE ~ ΔACD, x = 2ΔABE ~ ΔADC, x = 17Step-by-step explanation:
ΔABE ~ ΔACD
AC/AB = AD/AE
(10+x)/10 = (15+3)/15
1 +x/10 = 1 +0.2 . . . expand each ratio
x = 10(0.2) . . . . . . . subtract 1 and multiply by 10
x = 2
__
ΔABE ~ ΔADC
AC/AE = AD/AB
(10+x)/15 = (15+3)/10
10 +x = 27 . . . . . . . . multiply by 15
x = 17 . . . . . . . . . . . . subtract 10
_____
Additional comment
The triangles can be declared similar in 6 ways, but it does no good to match a marked side with an unmarked side. Hence, only two of the possible similarity statements will result in a solution for x.
Answer:
This will give you 5/5
x = 17
x=2
Assuming triangle ABE is similar to ACD
Assuming traingle ABE is similar to ADC
Step-by-step explanation:
18/10 = 1.8 (S.F)
15 x 1.8 = 27
27-10 = 17
x = 17
15+3=18
18/15= 1.2 (S.F)
10x1.2= 12
12-10=2
x=2

Find the length of the segment AB if points A and B are the intersection points of the parabolas with equations y=−x2+9 and y=2x2−3 . URGENT PLS HELP
Answer:
The length is 4
Step-by-step explanation:
Type in the equations into Desmos, and you will find the intersected points in the graph. Then just look at the distance between the 2 points
Answer:
AB=4
Step-by-step explanation:
1. Since you are finding the intersection points of two parabolas:
a. y=-x²+9
b. y=2x²-3
2. You have to set them equal to each other:
2x²-3= - x²+9
2x²+x=9+3
3x²=12
x²=4
This is the crucial part; the absolute value of x is equal to plus minus the square root of 4, since either -2 squared with parentheses or 2 squared is equal to 4.
√x²=±√4
x=±2
or
x=2; x=-2
3. Then you substitute them into each equation. For this step, any sign 2 will work.
a. y=-(2)²+9
y=-4+9
y=5
b. y=2(2)²-3
y=8-3
y=5
4. So our coordinates will be (2,5) and (-2,5). These are the points of intersection.
5. Now we use the distance formula:
[tex]\sqrt{(x₂-x₁)^{2} +(y₂-y₁)^{2} }[/tex]
The subscripts didn't work for this but I mean the square root of x 2 - x 1 in parentheses plus y 2 -y 1.
[tex]\sqrt{(2+2)^{2} +(5-5)^{2} }[/tex]=
√16=
4
The absolute value rule that I mentioned above doesn't work for this because its a distance and you can't have a negative distance.
So AB=4
