the graph of the equation y=2x-1 is shown in the coordinate plane.
wich lists contain only points that lie on the graph of y=2x-1?
A. (0,-1), (15,29), (2,3)
B. (2000, 1999), (3,5)
C. (-2,-3), (-5,-9), (0,0)
D. (-0.5, -2), (0.3, -0.4), (0.5, 0)
E. (1/4, -1/2), (4/5, 3/5)
Answer:
A, D, & E
Step-by-step explanation:
If you plug in the coordinates, they prove to be valid
(0, -1)
2(0) - 1
0 - 1 = -1
(15, 29)
2(15) - 1
30 - 1 = 29
(2, 3)
2(2) - 1
4 - 1 = 3
(-0.5, -2)
2(-0.5) - 1
-1 - 1 = -2
And so on. Just plug them in and see if it is correct.

Answer:
Step-by-step explanation:
∠5 = ∠1 {Alternate exterior angles are congruent}
8x - 19 = 7x - 3
Add 19 to both sides
8x = 7x - 3 + 19
8x = 7x + 16
Subtract 7x from both sides
8x - 7x = 16
x = 16
∠5 = 8x - 19
= 8*16 - 19
= 128 - 19
∠5 = 109
∠5 + ∠4 = 180 {linear pair]
109 + ∠4 = 180
∠4 = 180 - 109
∠4 = 71°

The 6 elephants at the zoo have a combined weight of 11,894 pounds. About how much does each elephant weigh?
Answer:
1982.33 pounds
Step-by-step explanation:
If they all weigh the same amount then you can figure it out by division.
11894/6=1982.33
Answer:
TO find out how much each elephant weighs you simply have to do 11, 894 divided by 6. Since the answer is a decimal (1982.33333333), I would just round it to the nearest tenth as it dosent specify where we have to round it to. SO, 1982.33333333 rounded to the nearest tenth is 1982.3

find the total cost 35$ with 50% discount
Answer:
The total cost will then be $17.5
Answer:
17.5 dollars
Step-by-step explanation:
Sale price = $17.5 (answer). This means the cost of the item to you is 17.5. You will pay $17. 5 for a item with an original price of $35 when discounted 50%. In this example, if you buy an item at $35 with 50% discount, you will pay 35 - 17.5 = 17. 5

Find the least square number divisible by 5, 10, 15. (a) 100 (b) 625 (c) 900 (d) 225
Answer:-
900
Verification:-
[tex]\\ \sf\longmapsto \dfrac{900}{5}=180[/tex]
[tex]\\ \sf\longmapsto \dfrac{900}{10}=90[/tex]
[tex]\\ \sf\longmapsto \dfrac{900}{15}=6[/tex]
Answer:
a) 100
→ [tex]\frac{100}{5}[/tex] = 20
→ [tex]\frac{100}{10}[/tex] = 10
→ [tex]\frac{100}{15}[/tex] = 6⅔
100 is not divisible by 15
b) 625
→ [tex]\frac{625}{5}[/tex] = 125
→ [tex]\frac{625}{10}[/tex] = 62.5
→ [tex]\frac{625}{15}[/tex] = 41.6
625 is not divisible by 10 and 15.
c) 900
→ [tex]\frac{900}{5}[/tex] = 180
→ [tex]\frac{900}{10}[/tex] = 90
→ [tex]\frac{900}{15}[/tex] = 60
900 is the correct answer.
d) 225
→ [tex]\frac{225}{5}[/tex] = 45
→ [tex]\frac{225}{10}[/tex] = 22.5
→ [tex]\frac{225}{15}[/tex] = 15
225 is not divisible by 15
900 is the correct answer.
Tonya has 5/8 yards of ribbon and is sharing it with Terri by cutting it in half. How much ribbon will each girl have?
Answer:
5/16
Step-by-step explanation:
you can't split 5 in half, so you need to multiply the fraction to make it so you can split it in half. Multiply the equation by 2
5/8 * 2=10/16
now you can divide it by two to get 5/16

what is the circumference of a circle with an area of 20 pi
Answer:
28.1 units
Step-by-step explanation:
Area of circle= πr², where r is the radius.
Given that the area is 20π,
20π= πr²
Divide both sides by π:
20= r²
Square root both sides:
[tex]r = \sqrt{20} [/tex]
[tex]r = \sqrt{4(5)} [/tex]
[tex]r = ( \sqrt{4} )( \sqrt{5} )[/tex]
[tex]r = 2 \sqrt{5} [/tex]
Circumference of circle= 2πr
Substitute the value of r:
Circumference of the circle
[tex] = 2(\pi)( 2\sqrt{5} )[/tex]
[tex] = 4\pi \sqrt{5} [/tex]
= 28.1 units (3 s.f.)

Answer:
<R=56 degrees; <Q=62 degrees; <S=62 degrees
Step-by-step explanation:
5x+12=4x+22 (This is because the two angles are congruent to each other.)
x+12=22
x=10
Now, plug it in.
5(10)+12=50+12=62 degrees
62(2)=124 degrees (This is because the two angles are congruent and equal)
180-124=56 degrees

The square root of the sum of 69 and 31 is an/a_____?
A.Rational Number
B.Irrational Number
C.Both rational and irrational
D.Neither rational nor irrational
Answer:
A. Rational number
Step-by-step explanation:
If you add both 69 and 31 it will give you 100. The square root of 100 is 10 and therefore it is a rational number
David uses software to draw two triangles. He finds that he can use a rotation and a reflection to map one triangle onto the other, and he finds that the image of vertex D is vertex L, the image of vertex V is vertex C, and the image of vertex W is vertex Y. In how many different ways can David write a congruence statement for the triangles? Complete the explanation.
Use the given information to select congruence statements.
△DVW ≅ △
△DWV ≅ △
△VDW ≅ △
△VWD ≅ △
△WDV ≅ △
△WVD ≅ △
There are __ more ways with the order of the triangles reversed. There is a total of __ ways to write a congruence statement.
Transformation involves changing the position of a shape.
The complete statement is:
There are _3_ more ways with the order of the triangles reversed. There is a total of _9_ ways to write a congruence statement.
From the question, we understand that:
[tex]\mathbf{\triangle DVW \cong \triangle LCY}[/tex]
This mean that, the following 6 statements can be used as the congruent statements
[tex]\mathbf{\triangle DVW \cong \triangle LCY}[/tex]
[tex]\mathbf{\triangle DWV \cong \triangle LYC}[/tex]
[tex]\mathbf{\triangle VDW \cong \triangle CLY}[/tex]
[tex]\mathbf{\triangle VWD \cong \triangle CYL}[/tex]
[tex]\mathbf{\triangle WDV \cong \triangle YLC}[/tex]
[tex]\mathbf{\triangle WVD \cong \triangle YCL}[/tex]
A triangle has 3 sides, and there are 2 triangles in the question.
The number (n) of congruence statements is:
[tex]\mathbf{n = 3^2 = 9}[/tex]
The remaining (r) number of congruent statement is:
[tex]\mathbf{r = 9 - 6 = 3}[/tex]
So, the blanks should be completed with 3 and 9

1: -6m,
2: 10.3-12m,
3: 28a-7,
4: 5/8h+7
Step-by-step explanation:
so, a helpful thing with these, is to add like terms. with #4, we see that the letter m is with both of the numbers, and since we are adding a bigger negative to a positive, the answer will be a negative with the number. for 6, 2 numbers have an x, and 2 do not. so we add or subtract the like pairs, as in the ones with the letters, and then a separate one for the one with no letters. for the last one, you always want to have a "common denominator" which is the number on the bottom. because 8 is already on the bottom, and 4 is divisible by 8 by 2, we inversely multiply the top and bottom numbers for the "3/4" and would get "6/8" to match the bottom denominator for "1/8" hope this helps
