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
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.

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

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 :)
Step-by-step explanation:
40 = 8y
40 ÷ 8= y
5 = y

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.
Answer:
true

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:
Number 1: 3 hours.
Number 2: $2434.04
Step-by-step explanation:
3/4 + 3/4 = 1 1/2 (after some simplifying)
1 1/2 + 1 1/2=3. She practiced 3 hours.
Number 2 will be harder to explain. We have 3 sides. That means 90 1/4 x 3. That is 270 3/4. 270 x 8.99 (8.99 per foot) gets us 2427.3, 3/4 x 8.99 (rounded to nearest hundreths) gets us 6.74. We add that together, and we get $2434.04.
I am pretty sure about 1, although not so sure about 2. Hope that helps you.
