Answer:
22.B) union
20.A) x+y=3^2
Step-by-step explanation:
22. The compound inequality [tex]1-4x < 21[/tex] and [tex]5x+2 > 22[/tex] is intersection, option A is correct.
21. [tex]x+y=3^2[/tex] is not a function. Option A is correct.
22. The compound inequality [tex]1-4x < 21[/tex] and [tex]5x+2 > 22[/tex] is an example of a compound inequality involving "and."
Both inequalities need to be satisfied simultaneously for the compound inequality to be true.
Hence, the compound inequality is intersection.
21. A function is a relationship between two variables in which each input value (x) corresponds to exactly one output value (y).
In this case, the equation [tex]x+y=3^2[/tex] does not represent a clear relationship between x and y.
[tex]x+y=3^2[/tex] represents a curve in the xy-plane rather than a function.
Hence, [tex]x+y=3^2[/tex] is not a function.

Gauss's Problem for the sum 1 + 2 + 3 + ... + n. Explain
your reasoning.
Answer:
Step-by-step explanation:
Hello, I will compute twice the sum so I need to compute,
[tex]\begin{aligned}1&+2&+...+&(n-1)&+n\\\\n&+(n-1)&+...+&2&+1\\\\-&-----&---&---&---\\\\(n+1)&+(n+1)&+...+&(n+1)&+(n+1)\end{aligned}[/tex]
1+n = n+1

Answer:
21). WX = 10
22). VW = 22
23). WY = 20
24). VX = 32
25). WZ = 30
26). VY = 42
Step-by-step explanation:
In the figure attached,
V, W, X, Y and Z are collinear.
VZ = 52, XZ = 20 and WX = XY = YZ
21). Since XZ = 20
XY + YZ = 20
WX + WX = 20 [Since, XY = WX = YZ]
2(WX) = 20
WX = 10
22). VZ = VW + WX + XY + YZ = 52
VW + 3(YZ) = 52 [Since, WX = XY = YZ]
VW + [tex]3(\frac{XZ}{2})[/tex] = 52
VW + [tex]\frac{3}{2}\times 20[/tex] = 52
VW = 52 - 30 = 22
23). WY = WX + XY
= 2(WX)
= 20
24). VX = VW + WX
= 22 + 10
= 32
25). WZ = 3(WX)
= 30
26). VY = VZ - YZ
= 52 - 10
= 42

Answer:
1a. A
1b. C
2 and 3 you have to draw
4a. 90 degree angle
4b. 180 degree angle
5a. 112 degrees
5b. 145 degrees
Step-by-step explanation:
for 5 you just subtract the given values from 360
Answer:
1a) A
(both B and C intersect at A)
1b) not sure
2a) draw 270 degree angle
360/4 = 90
90+90+90 = 270 = 3/4
2b) draw an angle less than 90 degree to get an acute angle
3a) first draw a 90 degree angle then divide the angle into two half and you ll get an angle of 45 degrees
90/2 = 45
but since you re not allowed to use compass or protactor so you might not get exact 45 but near to it
3b) draw a 90 degree angle facing downward and thats 270 degree
hope you get what im trying to say if not you can ask me again
4a) acute angle (90 degree)
4b) reflex angle (180 degree)
5a) 112 degree
118 + 130 + x = 360
248 + x = 360
x = 360 - 248
x = 112
5b) 145 degree
360 - 215 = 145
im posting the solutions and the answers of your previous questions here
6a) a = 60 degree
6b) b = 27 degree
because sum of interior angles of a triangle is 180
7a) b = 60 degree and a = 30 degree
7b) x = 36 degree and x = 36 degree
isosceles triangle has 2 same angles and 1 different
x + x + 108 = 180
2x + 108 = 180
2x = 180 - 108
2x = 72
x = 72/2
x = 36
8a) x = 95 degree
8b) a = 100 degree
9) steps;
draw a line segment QR
draw 120 degree angle at point Q
now open the compass of 2cm (or of your own choice) and draw a small arc from point Q such that it intersects line PQ and QR and name that point between QR as O
now from point O, open your compass of same measurement and draw an arc that cuts the previous arc
now draw a line from point Q to join the new formed arc
now using a protactor measure both the newly formed angles

Samantha conjectures that for x < -1, it is true that x5 - 2 > x. Is her conjecture correct? Why or why not?
Answer:
The conjecture cannot work for any negative numbers, It works for x > 1.3.
Step-by-step explanation:
An odd power preserves the sign. For |x| > 1, the power increases the magnitude. For x < 0, adding -2 only increases the magnitude more. A negative number of larger magnitude will not be "greater than" the reference. It will be "less than."
It only takes a counterexample to show the conjecture is incorrect.

(-2)^5 -2 ?? (-2)

Given
Represent the number with x
So:
[tex]5 * (x + 27) \geq 6 * (x + 26)[/tex]
Required
Determine the solution set
[tex]5 * (x + 27) \geq 6 * (x + 26)[/tex]

Distance Traveled and Gas Left in Tank Distance Traveled (in miles) 0 90 180 270 Amount of Gas Left in Tank (in gallons) 15 12 9 6 How many gallons of gasoline does the car have left after it has traveled 330 miles?
Answer:
4 gallons of gasoline the car has left after it has traveled 330 miles.
Step-by-step explanation:
We are given with the following data of Distance Traveled and Gas Left in Tank below;
Distance Traveled (in miles) Amount of Gas Left in Tank (in gallons)
0 15
90 12
180 9
270 6
330 ?
As we can see from the table that for every 90 miles of distance traveled, there has been a reduction of 3 gallons of gas which is left in the tank, i.e;
From 90 to 180 - Gas reduced from 12 to 9
This means that in 1 gallon of gas, the distance traveled is = [tex]\frac{90}{3}[/tex] = 30 miles
So, from distance 270 to 300, the amount of Gas Left in Tank = 6 - 1 = 5 gallons
From distance 300 to 330 miles, the amount of Gas Left in Tank = 5 - 1 = 4 gallons
Hence, 4 gallons of gasoline is left after the car has traveled 330 miles.
carlos wants to buy some new video games. each game he buys costs $36. help carlos by writing an equation that represents his total price.
Answer:
36 × (how many games he buys) = (the price)
Step-by-step explanation:
36 dollars multiplied by the number of games he buys will equal the price.
Example:
Let's say he bought 3 games.
36 × 3 = 108
So, in this case, he bought three games using $108 .

if john gets 1 apple and already has 20 in a basket how many do you have in total.
Answer:
21
Step-by-step explanation:
the reason it is 21 is because u have 20 then u add 1 so it is 21 20+1=21
━━━━━━━━━━━━━━━ ♡ ━━━━━━━━━━━━━━━
John already has 20 apples. If John gets 1 more apple, he would have 21 apples in total.
The word gets means addition. 20 plus 1 equals 21.
John has 21 apples after he gets another apple.
Ok technically I would have 0 apples since I didn't receive any only John did.
