Problem 2
Plot point L anywhere that isn't on segment JK. Draw a line through point L. I find it helps to make the lines parallel.
Next, use a compass to measure the width of segment JK. Keeping this same width, transfer the nonpencil end of the compass to point L. Draw an arc that crosses the line through L.
Mark this intersection point M. Lastly, use a pen or marker to form segment LM and erase everything else of that line.
======================================================
Problem 3
The ideas of the previous problem will be used here. We copied segment JK to form congruent segment LM. So JK = LM.
The same steps will be used to form segment GN where GN = EF. In other words, segment GN is a perfect copy of segment EF.
If you repeat these steps again, you'll get another segment of the same length. This segment goes from point N to point H. So NH = GN = EF
Then we can say,
GH = GN + NH
GH = EF + EF
GH = 2*EF

Suppose x = 7 is a solution to the equation 4x - 2(x + a) = 8. Find the value of a that makes the equation true
Answers
Answer:
[tex]a=3[/tex]
Step-by-step explanation:
So we have the equation:
[tex]4x-2(x+a)=8[/tex]
And we want to find a such that x = 7 is a possible solution.
To do so, substitute 7 for x. Thus:
[tex]4(7)-2(7+a)=8[/tex]
Multiply the left and distribute the right:
[tex]28-14-2a=8[/tex]
Subtract:
[tex]14-2a=8[/tex]
Subtract 14 from both sides:
[tex]-2a=-6[/tex]
Divide by -2: "
[tex]a=3[/tex]
So, the value of a is 3.
And our equation would be:
[tex]4x-2(x+3)=8[/tex]
And we're done!
Edit: Incorrect Answer
Answer:
a = 7
Step-by-step explanation:
Consider this question:
-2x=x^2-6
1) Rewrite the question by completing the square. Your equation should look like (x+c)^2=d or (x-c)^2=d.
2) What are the solutions to the equation?
Answers
Answer:
see explanation
Step-by-step explanation:
(1)
Given
- 2x = x² - 6 ( subtract x² from both sides )
- x² - 2x = - 6 ( multiply through by - 1 )
x² + 2x = 6
To complete the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(1)x + 1 = 6 + 1
(x + 1)² = 7
(2)
Take the square root of both sides
x + 1 = ± [tex]\sqrt{7}[/tex] ( subtract 1 from both sides )
x = - 1 ± [tex]\sqrt{7}[/tex]
Solutions are x = - 1 - [tex]\sqrt{7}[/tex] , x = - 1 + [tex]\sqrt{7}[/tex]
Round 7.21 to the nearest whole number.
Answers
Answer:
7.21 ≈ 7Step-by-step explanation:
If you are rounding to the whole number you are rounding to ones so you need to look at the tenth digit:
2<5 so 7 stays the same (rounding down)
7.21 ≈ 7
The nearest whole number for the given number is 7.
What is rounding off?To change a number into an approximation having fewer significant digits. For example :-
Round off 15.4 to 15, round off 15.51 to 15.5 or to 16, round off 0.499 to 0, and round off 970,000 to 1 million.
Given is a number 7.21,
We know that, if the digit is less than 5, round down and if the digit is 5 or more than 5, round up.
Since, numbers after the decimal is not greater than 5, therefore, it will not change and will remain 7.
Hence, the required whole number is 7.

Take any two points .
I took (0,7) and (3,-2),then slope=(y2-y1)/(x2-x1)=(-2-7)/(3-0)=-9/3=-3
you can take any two points.

Answers
Answer:
Step-by-step explanation: multiply 2 with 3x-1
6x-2
multiply 9 with x-2
9x-18
form equation:
2(3x-1)=9(x-2)-7
or, 6x-2=9x-18-7
or, 9x-18-7=6x-2
or, 9x-6x= -2+18+7
or, 3x=23
or, x=23/3
Ans: x= 7.67
6x - 2 = 9x - 18 - 7.
Combine like terms. 6x - 2 = 9x - 25.
Then add 2 and subtract 9x.
-3x = -23.
Divide the negative
3x = 23. Then divide 3

8x - 3 = 3x + 2
A. One solution
B. Infinite solutions
C. No solutions
please explain how you got it
Answers
A one solution because it's x=1
Step By Step explanation:this is the original problem
8x-3=3x+2
we want to have x by itself so. . .
we add three on both sides. it cancels -3. And 2+3=5
8x=3x+5
we subtract 3x on both sides so 8x-3x=5x and 3x cancels on the other side
5x=5
we divide by 5 on both sides to get x by itself
x=1
if it was 1=1 or x=x (the same on both side) it would've been infinite solutions. if the numbers didn't match like 4=6 it would've been no solution
Which point is an x-intercept of the quadratic function f(x)=(x-8)(x+9)
Answers
Step-by-step explanation:
An x-intercept of a function occurs when f(x) = 0.
In f(x) = (x-8)(x+9), f(x) will be 0 if either (x-8) is 0 or (x+9) is 0.
Hence, f(x) = 0 when x = 8 or x = -9.

Triangle ABC is a right triangle, angle B is the right angle, angle A is
8x + 2, and angle C is 9x + 3.
What is the measurement of angle A?
ОООО
5°
42°
45°
48°
Answers
A triangle has to equal 180 degrees in total. Because you know it is a right triangle and b is the right angle you make angle a plus c equal 90. You add together 8x and 9x to get 17x and add the 2 and 3 to get 5. You have to solve for x so you subtract 5 from both sides to get 17x = 85. To get x alone you divide both sides by 17 giving you x=5. Now that you have x you plug it into to the equation for angle a. This gives you 8(5)+2 which equals 42.
8x+2+9x+3=90
17x+5=90
17x=85
X=5
8(5)+2=
40+2=42
