Answer:
79°
( vertically opposite angles are equal. So, <AOB = < A'OB' )
Answer:
∠ A'OB' = 79°
Step-by-step explanation:
∠ AOC = ∠ C'OA' = 35° ( vertical angles )
BOB' is a straight angle , thus
∠ COB' = 180° - (79 + 35)° = 180° - 114° = 66°
C'OC is a straight angle, thus
∠ A'OB' = 180° - (66 + 35)° = 180° - 101° = 79°

slove each system of equations using graphing, substitution or elimination. y=2x-3 y=2x+3
Answers
y=2x-3
y=2x+3
Since the both expressions 2x-3 and 2x+3 are equal to y, set them equal to each other forming an equation in x.
2x-3=2x+3
Cancel equal terms on both sides of the equation
-3=3
The statement is false for any value of x and y , so there is no solution
Vary the scale factor n from values less than 1 to values greater than 1. How do the points in the resulting images differ from the corresponding points on the preimage? Describe the general location of the points relative to the center of dilation. What happens to the logo of the sailboat as you vary the scale factor?

Answers
Answer: For values of n < 1, all the points on the image move closer to the center of dilation and the logo shrinks. For values of n > 1, all the points on the image move farther from the center of dilation and the logo expands.

The coach took a digital photo of the new cycling team bike. She sent a 4 cm-by-6 cm photo to each team
member.
1. If the photo were enlarged to 150% of its original size, what would be its new length (long side)?
9
2. Suppose you want to make a 2 cm-by-3 cm copy of the original photo.
What percent should you use?
50%
3. What will be the measurement for each angle in the smaller photo?
Answers
Answer:
1. 9 cm
2. 50%
3. Assuming the photo is a rectangle, the answer would be 90 degrees on every angle (in a dilation, angle measurements are congruent).
Step-by-step explanation:
1. The long side is clearly the 6 cm side. multiply it by 1.5x (150%) and you get 9.
2. 2 is 50% of 4 and 3 is 50% of 6.
3. Assuming the photo is a rectangle, the answer would be 90 degrees on every angle (in a dilation, angle measurements are congruent).

Find the measures of the sides of triangle JKL, then classify it by its sides J(-3, 2), K(2,6), L(8, -1)
Answers
Given:
The vertices of the triangle JKL are J(-3, 2), K(2,6), L(8, -1).
To find:
The measures of the sides of triangle JKL and classify it by its sides.
Solution:
Distance formula:
[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
Using distance formula, we get
[tex]JK=\sqrt{(2-(-3))^2+(6-2)^2}[/tex]
[tex]JK=\sqrt{(2+3)^2+(4)^2}[/tex]
[tex]JK=\sqrt{(5)^2+(4)^2}[/tex]
[tex]JK=\sqrt{25+16}[/tex]
[tex]JK=\sqrt{41}[/tex]
Similarly,
[tex]KL=\sqrt{\left(8-2\right)^2+\left(-1-6\right)^2}=\sqrt{85}[/tex]
[tex]JL=\sqrt{\left(8-\left(-3\right)\right)^2+\left(-1-2\right)^2}=\sqrt{130}[/tex]
Now,
[tex]JK^2+KL^2=(\sqrt{41})^2+(\sqrt{85})^2[/tex]
[tex]JK^2+KL^2=41+85[/tex]
[tex]JK^2+KL^2=126[/tex]
[tex]JK^2+KL^2\neq JL^2[/tex]
Since, measure of all sides are different and sum of squares of two smaller sides is not equal to the square of largest side, therefore the triangle is scalene triangle.
Overnight the temperature went from 39*F to -5*F. What is the difference in temperature?
Answers
Explanation: Since the new temperature is a negative number and the old was positive, you add them together. However instead of (-5) +39 (which the answer would be 35), you would write 5 +39 because -5 is 5 spaces away from 0. You can also check by using the equation 39 -44. You would get the answer -5, proving that the answer is indeed -44 degrees.

Answer:
y = -2/3x -5
Step-by-step explanation:
First, let's fill in our equation of y = mx + b
(6, -9) is the coordinate we will be subsituting
If the equation that s to the one we are solving we must turn its slope into it's negative reciprocal, which would go from 3/2 to -2/3
Now let's substitute and solve
y = mx + b
(-9) = -2/3(6) + b
-9 = -4 +b
+4 +4
-5 = b
Now we create the equation
y = -2/3x -5

Answer:
D) $400
Step-by-step explanation:
We are given the relations ...
s = 0.75m
s = 300
Then we can find m by equating the expressions for s:
0.75m = 300
m = 300/0.75 = 400
Meifen's savings is $400.

Answer:
(x, y) = (-2, 1)
Step-by-step explanation:
Equate the two expressions for y.
-5x -9 = 2x +5
-14 = 7x . . . . . . . .add 5x-5
-2 = x . . . . . . . . . divide by 7

Lianne is saving to buy a DVD player that costs 2 1\2 times her weekly allowance. If she spends 3\4 of her allowance on other things, how long will she take to save the money for the DVD player?
Answers
Answer:
She will take 10 weeks to save the money for the DVD player
Step-by-step explanation:
Let w = Lianne's weekly allowance.
The DVD player costs 2 1/2 times her weekly allowance, thus
DVD cost = 5/2w
She gets w every week but spends 3/4w on other things, thus the remaining money is
Weekly savings =w - 3/4w = 1/4w
To know the number of weeks needed, we divide the DVD cost by the weekly savings:
[tex]\displaystyle N = \frac{\frac{5}{2}}{\frac{1}{4}}[/tex]
Operating:
[tex]\displaystyle N = \frac{5}{2}*\frac{4}{1}[/tex]
N = 10
She will take 10 weeks to save the money for the DVD player
