Answer:
c = -11
expression value = 245
c = 0
expression value = 3
c = 15
expression value = 453
Step-by-step explanation:
Given expression = [tex]2c^2 + 3[/tex]
for c = -11 , we put c in place of c in given expression
[tex]2(-11)^2 + 3 = 2(121) + 3 = 242 + 3 = 245[/tex]
for c= 0
[tex]2(0)^2 + 3 = 2(0) + 3 = 0 + 3 = 3[/tex]
for c = 15
[tex]2(15)^2 + 3 = 2(225) + 3 = 450 + 3 = 453[/tex]

Answer: angle x is 52°
Assuming the line JK is parallel to HI. That should be given.
Step-by-step explanation:
Angle JKA is congruent to angle HIA, so both measure 62°
Add measure of AHI to JKA.
66+62= 128.
Angles of a triangle always add up to 180° so you can subtract 128 from 180 to find x.
180-128= 52°

Answer:
1. 2/21
2. 7/45
3. 9/26
4. 4/61
5. 3/29
6. 8/61
Step-by-step explanation:
I'll just explain number one, since you can do the same thing to solve all the others.
You start with 10 1/2. You can make this an improper fraction by multiplying 10 and 2, then adding one. This leaves you with 21/2. The reciprocal of a fraction is just the numerator and denominator of the fraction flipped. So, you get 2/21.

solve: 5 (x+2) +2x
make sure to show your work
Answer:
5 (x+2) +2x is equal to 7x + 10
Step-by-step explanation:
To find the value of this equation you would have to apply the distributive property by changing 5 (x+2) to 5x +10. (When applying the distributive property you will always multiply the numbers in the parentheses by the number on the left of it). Then you would combine like terms by adding 2x and 5x together. You will then have 7x + 10.
Step-by-step explanation:
1.) Distribute = 5x+10
2.) Collect Like-Terms = 5x & +2x
3.) Add 5x and +2x , which = 7x
Now you have your answer, which is: 7x + 10.

Answer:
Options 1 and 4 are the only other parallel lines
Step-by-step explanation:
Plug the equation into a graphing calculator and observe your results.
Answer:
The answers are y = −4x, 16x + 4y = 9, and y = −4x + 15
Step-by-step explanation:
y=-4x has the -4 as slope so it parallel
y = −4x + 15 also has the -4 as a slope so it parallel
16x + 4y = 9 u have to solve.
4y=-16x+9 First step is to subtract -16 both sides (which just tosses -16 to the other side where the 9 is.
y=-4x+2.25 Divide everything by 4

9. Suppose the perimeter of a triangle is given by
P = 13x + 5y, and two of its sides have lengths of
2x + y and 8x + 4y. What is the length of the third
side?
Answer:
The length of the third side is 3x
Step-by-step explanation:
Algebraic Expressions
This problem deals with the ability to manage algebraic expressions in two variables.
Recall the perimeter of a triangle is the sum of its three sides. We already know the perimeter of the triangle is:
P=13x+5y
We also know the lengths of two of its sides are 2x+y and 8x+4y. The sum of those sides is:
S2=2x+y+8x+4y
Joining like terms:
S2=10x+5y
The third side must be the difference between the perimeter and the sum above:
S3=13x+5y-(10x+5y)
Operating:
S3=13x+5y-10x-5y
Joining like terms:
S3=3x
The length of the third side is 3x
What is the midpoint of 50 and 49
The Midpoint between 50 and 49 is 49.5
What is Midpoint?The exact middle point between two numbers is referred to as the midpoint. By adding the two numbers together and then dividing the result by two, we can determine the midway of the two supplied values. It is the two numbers' average.
Given:
First number= 50
and second number= 49
So, the Midpoint between 50 and 49
= First number + second number/2
= 50+ 49 / 2
= 49.5
