Answer:
x= -64°, y= -63°, z=-57°
Step-by-step explanation:
→Solution,
Here,
60°=(-y-3)°[The opposite sides of a parallelogram are equal]
⇒y= -60°-3°
⇒y= -63°
⇒60°+(-2x-8)°=180°[Sum of co-interior angles is 180°]
⇒52°-2x=180°
⇒52°-180°=2x
⇒x= -128°/2
⇒x= -64°
⇒60°+(-2z+6)°=180°[Sum of co-interior angles is 180°]
⇒66°-2z=180°
⇒66°-180°=2z
⇒z= -114°/2
⇒z= -57°

See figure below.
Step-by-step explanation:
Since the dilation is 1/5 with respect to the origin, divide each x- and y-coordinate by 5 to find the new points. Then plot them. See figure below.
Select the equation that matches the written description.
A number, y is eight less than negative nine times a number,x.
(А)
y = -4x + 8
B
y = 3x + 8
y = -9x - 8
D
y = 5x + 8
Answer:
C. y = -9x - 8
Step-by-step explanation:
Setting up the equation:
eight LESS (so minus sign before the 8) THAN (so 8 is being subtracted from the -9x) negative (-) nine TIMES (multiplication) a number, (variable) x.
We want to get the variable y alone, so this can be written as y = -9x - 8

I have absolutely no idea what to do here. Can someone break this down for me please?
Answer:
Step-by-step explanation:
The task is to draw the parabola of the equation [tex]x^{2} -4x+4[/tex] on the given graph.
The first step we can take to doing this is to use the table on the left hand side to work out our x and corresponding y-values to use as plotting coordinates. To do this you want to substitute the given value for x which will give you a corresponding y-value.
E.g:
x | [tex]x^{2} -4x+4[/tex] | y
0 | [tex](0)^{2} -4(0)-4[/tex] | -4
Here we have gotten the coordinates (0, -4) so this will be a point on the graph.
Repeat with all other values on the table and you should get a bunch of dots which lead upwards in a curved line from a point. Extend the lines to form a parabola shape (A u-shape).
Once you have drawn the graph, label the parts.
Roots: The places where the line crosses the x-axis
Vertex: The lowest point of the parabola
Line of symmetry: The vertical line in which the parabola reflects/ is the same either side (Has equation x=_).
y-intercept: The point where the line crosses the y-axis.

Question 21:
Name the angle:
Answer: Either angle QPO or angle OPQ
Explanation:
When naming an angle, we always have the vertex as the middle letter. That vertex is P. It's where the two rays are joined.
So we could have the name "angle QPO" or "angle OPQ" since the order of the other letters doesn't matter. All that we care about is P is in the middle.

To convert the parametric curve into Cartesian form,
rewrite the equation for [tex]x[/tex] to make [tex]\sin t[/tex] the subject:
[tex]x=2\sin t[/tex]
[tex]\implies \sin t=\dfrac{x}{2}[/tex]
Substitute this into the given equation for [tex]y[/tex]:
[tex]\begin{aligned}y & =3 \sin t\\\implies y & = 3 \left(\dfrac{x}{2}\right)\\y& = \dfrac{3}{2}x\end{aligned}[/tex]
Therefore, the Cartesian form of the parametric curve is:
[tex]y=\dfrac{3}{2}x[/tex]

A store is giving out cards labelled 1 through 10 when customers enter the store. If the card is an even number, you get a 10% discount on your purchase that day. If the card is an odd number greater than 6, you get a 40% discount. Otherwise, you get a 20% discount. The table shows the results of 400 customers. What is the relative frequency for each discount? Use pencil and paper. If the manager of the store wants to approximately half of the customers to receive the 20% discount, does this seem like an appropriate method? Explain.
Answer:
Relative frequency for each discount :
10% - 0.4925, 20% - 0.3325, 40% - 0.175
Since only 33.25% of customers got 20% discount, it is not an appropriate method.
Step-by-step explanation:
relative frequency = number of frequency/total number of frequency
you can find out relative frequency for each number and add them up to get relative frequencies of discounts.

Answer:
1st option y-5 = 3(x-1)
Step-by-step explanation:
graph shows y intercept of 2
1st option has a y intercept of 2
Answer:
Option 1
Step-by-step explanation:
Clearly, the slope of the line is 3. (As it cannot be negative in this case and it's more vertical so it's not 1/3)
The point slope form is written as :
y - y₁ = m(x - x₁)
Substituting m = 3 :
y - y₁ = 3(x - x₁)
Option 1 is the only option with the value of m as 3.
Hunter misses 10% of the free throws he attempts in a season. How many total free throws did he attempt if he missed 54?
Answer:
540
Step-by-step explanation:
If you divide 540 by 100 (100%) you get 5.4 then multiply it by 10 (10%) to get 54 again. THIS WAS TO CHECK TO GET: 10% or 100% is 10 so multiply 54•10=540

Solve -3(x - 4) > -2x + 5
Answer:
x<7
Step-by-step explanation:
-3(x - 4) > -2x + 5 Distribute
-3x+12>-2x+5 Subtract 12 from both sides
-3x>-2x-7 Add 2 to both sides
-5x>-7 Simplify
x<7
Answer:
x < 7.
Step-by-step explanation:
-3(x - 4) > -2x + 5
-3x + 12 > -2x + 5
-3x + 2x > 5 - 12
-x > -7 Note: we divide by -1 so the sign flips:
x < 7.

What is the next step in solving this augmented matrix using the gauss-jordan elimination method? a. convert the matrix to the linear system form. b. divide r2 by 2 and r3 by 3. c. the matrix is solved. d. this is an inconsistent matrix that cannot be solved. e. divide r1 by 2 and r3 by 3.
Based on the Gauss-Jordan Elimination method, and the matrix given, the next step would be to b. divide R2 by 2 and R3 by 3.
What is the next step in the Gauss-Jordan Elimination method?The first row has already gone as low as it can so rows two and three need to be worked on.
The best way to do this is to divide Row 2 by 2 and Row 3 by 3. This then leads to the augmented matrix becoming:
[1 0 0 I 5]
[0 1 0 I 4]
[0 0 1 I 3]

Answer:
A) [tex]0.13[/tex]
Step-by-step explanation:
If a function [tex]f(x)[/tex] is continuous over the interval [tex][a,b][/tex], then the average rate of change over that interval is [tex]\displaystyle \frac{f(b)-f(a)}{b-a}[/tex]:

Answer:
s = 132 square cm
Step-by-step explanation:
s = area of base + area of lateral faces
Area of base (triangle)
A = 1/2bh
A = 1/2(3)(4)
A = 1/2(12)
A = 6
There are two bases (triangles), so multiply the answer by 2.
6 x 2 = 12
Area of lateral faces (3 rectangles)
First rectangle:
A = lw
A = 5(10)
A = 50
Second rectangle:
A = lw
A = 4(10)
A = 40
Third rectangle:
A = lw
A = 3(10)
A = 30
Add all the areas together.
s = 12 + 30 + 40 + 50
s = 132 square cm
