Answer:
Riko is wrong because she uses the wrong formula.
Step-by-step explanation:
Given the coordinate points (-2, -3) and (2, -5)
We are to find the distance between the two points
Using the formula:
D = √(x2-x1)²+(y2-y1)²
From the coordinates x1 = -2, y1 = -3, x2 = 2 and y2 = -5
Substitute
D = √(2-(-2))²+(-5-(-3))²
D= √(4)²+(-2)²
D = √16 + 4
D = √20
D = √4*√5
D = 2√5
This shows that Riko is wrong because she uses the wrong formula.
Answer:
No, Riko is not correct. The points do not have the same x-coordinates. If you connect the points, they do not form a horizontal or vertical line, so you cannot count spaces or use absolute value to find the distance.
Step-by-step explanation:
The nth term of a sequence is n-4
a) Work out the first three terms of the sequence.
b) Work out the tenth term of the sequence.
Step-by-step explanation:
a) 1st term: 1-4= -3
2nd term: 2-4= -2
3rd term: 3-4= -1
b) FORMULA: a1 (n-1) d
a1 (first term): -3
d (difference): 1
-3 (n-1) 1
-3-1n-1= -1n-4

about 7/10of the surface of the earth is covered with water. express this as an equivalent fraction with 100 as the denominator. the fraction with 100 as the denominators are known as per cent. 50/100 means 50 per cent. so what percentage of the earth's surface is covered with water? what percentage is covered with the land?

3x -(-2-4x)=
What does this equals??
Answer:
7x + 2
Step-by-step explanation:
Original Equation: 3x − ( −2 − 4x)
First, we distribute the negative sign:
= 3x + (−1) (−2−4x)
=3x + (−1)(−2) + (−1)(−4x)
= 3x + 2 + 4x
Using the communitive property of addition, we can write:
= 3x + 4x + 2 (Instead of 3x + 2 + 4x)
Combining like terms, we get:
= (3x + 4x) + 2
= 7x + 2

The quotient of a number and 6 minus -1/3 is equal to the quotient of the number and 8. What is the number?
Answer:
x = 8
Step-by-step explanation:
Let the number = x
x/6 - 1/3 = x/8
-1/3 = x/8 - x/6
-1/3 = (6x-8x)/48
-1/3 = -2/48x
Divide both sides by -2/48
x = -1/3 ÷ -2/48
= -1/3 × -48/2
= 48/6
= 8
x = 8
The number = 8

solve x-5y=-30, 3x+5y=10 show your work
1) x = 5y - 30
2) x = - 1.6y + 3.3
im assuming these are 2 different questions
Explanation:1)Start with the equation:
x - 5y= -30
add 5y to both sides:
x = 5y - 30
Your answer is x = 5y - 30
2)Start with the equation:
3x+5y=10
subtract 5y from both sides:
3x = -5y + 10
divide by 3 to get x singular
x = - 1.6y + 3.3
Your answer is x = - 1.6y + 3.3
Hope this helps :)

7th gradeeee
Answer:
0=0
Step-by-step explanation:
Add zero
0+2=2
2=2
Subtract 2 from both sides of the equation
2=2
2−2=2−2
Simplify
Combine like terms
2−2=2−2
0=2-2s
or
0=2s-2
0=0
Answer 0=0
please hellp find x y and z
Answer:
angle x = 98
angle y = 82
angle z = 82
Step-by-step explanation:
angle y + 98 = 180; therefore, angle y = 82 degrees
angles z and y are alternate interior angles and are congruent (equal)
angle x is 98 degrees because angles x and y are same-side interior and their angles are supplementary (add up to 180 degrees)

divide 4/20=5
5x4=20
The constant is 5
Answer:
B. 5
Step-by-step explanation:
1/k = 4/20 (Given)
1/k = 1/5 (Reduce)
1 = 1/5k (Multiply k on both sides)
5 = k (Divide 1/5 on both sides)
