Graph each equation. Determine the solution of the system of equations. Use pencil and paper. Explain how to find the equation of a line that intersects the system of equations at the same point.
1) x=y
2) 4x= 3y - 3
9514 1404 393
Answer:
see attached
use the point-slope form
Step-by-step explanation:
Substitution works to find the solution.
4x = 3x -3
x = -3 = y
The solution is (x, y) = (-3, -3).
__
The first equation graphs as a line through the origin with a slope of 1.
The second equation graphs as a line through (0, 1) with a slope of 4/3, that is, a rise of 4 for each run of 3.
The two lines intersect at (x, y) = (-3, -3), so that point, together with the y-intercepts, can be used to draw the lines.
_____
A line that intersects point (-3, -3) can be written in point-slope form as ...
y +3 = m(x +3) . . . . . for some slope m.
If you were to choose m = -1, this becomes ...
y +3 = -(x +3)
y = -x -6 . . . . . . rearranged to slope-intercept form
Determine if the statement below is always true, sometimes true, or never true.
The sum of an integer and 10% of the integer is greater than or equal to the integer.
Explain your reasoning.
Step-by-step explanation:
There are many integers that will satisfy the conditions mentioned. For example, -9 and -2 would satisfy both conditions. These integers are both greater than -10, and when added together, they equal -11, which is less than -10.
Answer:
The statement is true when the integer is positive and false when the integer is negative. Meaning sometimes true would be the answer.

How much did the two heaviest tomatoes weigh all together?
Answer:
1 and 6/8
Step-by-step explanation:
1/2 is equivalent to 4/8 when you multiply both the numerator and denominator by 2. So since there are two tomatoes that weigh 1/2 it would be 4/8+4/8= 1. Next you would add 3/8+3/8=6/8. So when you add 1 whole and 6/8 you get 1 and 6/8.

The temperature in Salt Lake City was -10.6°C. Which absolute value equation best describes how many degrees the temperature was below 0°C?
A) |-10.6| = -10.6
B) |-10.6| = -10
C) |-10.6| = 10
D) |-10.6| = 10.6
I have a feeling that it’s D but at the same time, A...
The absolute value equation best describes how many degrees the temperature was below 0°C is 10.6.
What is absolute value or modulus ?
The absolute value of a number refers to the distance of a number from the origin of a number line. The absolute value of any integer, whether positive or negative, will be the real numbers, regardless of which sign it has.
For example: 5 is the absolute value for both 5 and -5.
According to the question,
The temperature in Salt Lake City was -10.6°C.
Then, absolute value equation best describes how many degrees the temperature was below 0°C =
⇒ Absolute value = modulus value
= |-10.6|
= 10.6
Hence the absolute value = 10.6

Answer:
The diagonal is 39.54 in
The baton will fit in the box if it is placed in the direction of the diagonal of the cube since:
39.54 inches > 38 inches
Step-by-step explanation:
Answer: Yes, she could.
Step-by-step explanation:
To find the answer we first have to find the length of the interior diagonal.
I used Phytagoras' theorem to find the diagonal length of the base of the box. Then to calculate x (hypotenuse), the diagonal length of the box, I again used the Phytagoras' theorem using the length of the base and the height of the box.
I found out that the diagonal interior length of the box is 39.5 in.
Since the baton is 38in and the length of the box is 39.5 in, Kylie can fit the baton inside the box with 1.5 in spare length.

Answer:
x = 15, Angles are both 130!
Step-by-step explanation:
Since this is an example of Alternate Exterior Angles, you could set these equal to eachother!
9x-5 = 7x + 25
-7x -7x
Subtract 7x from both sides.
2x - 5 = 25
+5 +5
Add 5 to both sides.
2x = 30
Divide by two to get x by itself .
x = 15, now you can plug this in for X and get the angle
9(15) - 5 = 130
Answer:
Since this is an example of Alternate Exterior Angles, you could set these equal to each other! its 125
Step-by-step explanation:
9x-5 = 7x + 25
-7x -7x
Subtract 7x from both sides.
2x - 5 = 25
+5 +5
Add 5 to both sides.
2x = 30
Divide by two to get x by itself .
x = 15, now you can plug this in for X and get the angle
9(15) - 10 = 125

22-W > 4 w=20
True or false?
Answer:
False
Step-by-step explanation:
If the 4 and w are multiplied, I assume they are, then you would find what number multiplies by 4 to get 20(that would be 5).
You would then plug in 5 = w in for 22 - w which would get you 17.
17 > 20, which is false.

Explain how to solve the equation and how to check the solution. 40 = 8y
answer is
Use the inverse operation to isolate the variable. Undo multiplication by dividing by 8 on both sides of the equation. Simplify by completing the divisions, 40 ÷ 8 = 5, and 8 ÷ 8 = 1. The solution is y = 5. Check the solution by substituting 5 for y in the original equation, and then simplify. 8 × 5 = 40 and 40 = 40 is a true statement, so 5 is the solution.
Answer:
U already know the answer, then why ask?? I'll explain it once again, tho :)
