Answer:
C
Step-by-step explanation:
It’s convenient that there are only two x values you need to check, -2 and 2. Just insert it to see what y is appropriate.
x = -2: y > 6 + 3 = 9 (and y > -2 + 2 = 0 which is redundant here)
x = 2: y > 2 + 2 = 4 (and y > -6 + 3 = -3 which is redundant here)
So, neither B nor D is in the solution set with 5 < 9 and -5 < 9.
A isn’t in the solution set either with -5 < 4.
C is in the solution set with 5 > 4.

c

All the sides of a quadrilateral measure 5 cm. What else must be true about this shape? Select all that apply. a.The diagonals are congruent. b.The diagonals are perpendicular. c.Consecutive angles are congruent. d. Opposite angles are congruent.
Answer:
a.The diagonals are congruent.
d. Opposite angles are congruent.
Step-by-step explanation:
From the above question, we are told that:
All the sides of a quadrilateral measure 5 cm.
This means this quadrilateral is a square.
The properties of a square states that:
1) Opposite sides of a square are equal each other or congruent.
2) Opposite angles are equal each other or congruent
3) Consecutive angles of a square are supplementary angles which means that they add up to 180.
4) A square has two diagonals and they are congruent or equal to one another.
Therefore, the correct options are options a and d

9514 1404 393
Answer:
5/12
Step-by-step explanation:
Since Pedro had 1/3 of the book remaining at the end of the day, he had read a total of 2/3 of the book. If n represents the amount read at night, you have ...
1/4 + n = 2/3
3 +12n = 8 . . . . . multiply by 12
12n = 5 . . . . . . . .subtract 3
n = 5/12 . . . . . . divide by 12
Pedro read 5/12 of the book at night.
_____
Since Pedro reads only a fraction of the book, it is not a "mixed number."
__
The solution is equivalent to finding the difference ...
2/3 - 1/4
= 8/12 - 3/12 = 5/12

The population of a city decreases by 1.6% per year. If this year's population is 320,000, what will next year's population be, to the nearest individual?
Answer:
314,880
Step-by-step explanation:
If the population decreases by 1.6% per year, this means the population is 98.4% of the population of the previous year. What this means is we can multiply the current population, 320,000, by 98.4/100, as 98.4/100 is equivalent to 98.4%. This gets us 314,880.
Answer:
314880

In the figure shown below, line “m” and line “n” are parallel what is the value of x?
Answer:
x = 20°
Step-by-step explanation:
3x - 10° + 5x + 30° = 180° { being co-interior angles }
8x + 20 ° = 180°
8x = 180° - 20°
8x = 160°
x = 160° / 8
x = 20°
someone has only quarters and dimes in his piggy bank. He has 152 coins in the piggy bank with the value of $30.50. Determine the system of equations that model this problem. Solve the system. How many quarters and dimes does Everett have
Answer:
102 quarters
50 dimes
Step-by-step explanation:
y = dimes
x = quarters
We can use the following equations to solve
[tex]152 = x + y[/tex]
[tex]30.5 = .25x + .10y[/tex]
We isolate for y in the first equation
[tex]y = 152 - x[/tex]
We plug into second equation
[tex]30.5 = .25x + .10(152 - x)[/tex]
Reduce
.15x = 15.3
x = 102
We then plug this number in first equation
152 = 102 + y
y = 50
Identify the term that completes the equation.

Answer:
1: b. YZ, see "geometric mean theorem" in Wikipedia
2: a. sin Y = 7.4/10.9 ≈ 0.68, sine = opposite/hypotenuse
3: c. tan P = 8.5/16 ≈ 0.53, tangent=opposite/adjacent
4: a. AC = 11.7, sine = opposite/hypotenuse, sin(43) = 8/AC
5. KM = 10.68 use Pythagorean Theorem

measure of angle K = 55 degrees, M and K are complementary angle
Step-by-step explanation:
i hope this help
The term that completes the equation is YZ.
Option D is the correct answer.
We have,
From the figure,
∆WXY and ∆XYZ
∠WXY = ∠XZY = 90
∠ZYX = ∠XYW (common angle)
∆WXY ≅ ∆XYZ
And,
∆WXY and ∆WXZ
∠WXY = ∠WZX = 90
∠YWX = ∠XWZ (common angle)
∆WXY ≅ ∆WXZ
Now,
From (1) and (2),
∆XYZ ≅ ∆WXZ
This means,
The corresponding sides are proportional.
We can write as,
YZ/XZ = XZ/ZW
XZ² = WZ x YZ
Thus,
The term that completes the equation is YZ.

The movie club is having a new member sale, so Mindy signs up. The equation -0.4x + 0.05y - 1.25 = 0 relates y, the total cost, and x, the number of months. What is the y-intercept of the line represented by the equation?
Answer:
Y intercept : ( 0 , 25 )
Step-by-step explanation:
Answer:
(0, 25)Step-by-step explanation:
We need to convert function to slope-intrcept form y=mx+b, where:
-0.4x + 0.05y - 1.25 = 0 {multiply both sides by 20}
-8x + y - 25 = 0 {add (8x+25) to both sides}
y = 8x + 25 ⇒ b = 25
Therefore y-intercept of the line is (0, 25)
