The question is incomplete.

This is the complete question as I found in internet:

<span>Use substitution to determine which of the following points is a solution to the standard form equation below 5x-2y = 10

these are the points:
</span>
-1,5

1,5

0,-5

0,5

Answer: (0, -5)

Explanation:


point          x           y        5x - 2y = 10 ?


-1,5         -1           5         5(-1) - 2(5) = - 5 - 10 = - 15 ≠ 10 ⇒ not a solution

1,5            1          5         5(1) - 2(5) = 5 - 10 = 5 ≠ 10 ⇒ not a solution
 
0,-5           0        -5           0 -2(-5) = 10 ⇒ a solution

0,5             0         5          0 - 2(5) = - 10 ≠ 10 ⇒ not a solution

The first 4 terms of a geometric sequence are 2, 6, 18, 54. Part A: Find the common ratio. Remember the common ratio is the numb
ra1l [238]

Answer:

Common ratio is 3

The three terms are 162, 486, 1458

Step-by-step explanation:

Given: The first 4 terms of a sequence are 2,6,18,54

To find:

A. the common ratio

B. the next 3 values in the geometric sequence

Solution:

Geometric sequence is a sequence in which each of the terms is obtained by multiplying the previous term by a fixed number.

A.

\frac{6}{2}=3\\\\\frac{18}{6}=3\\\\\frac{54}{18}=3

So, the common ratio is 3

B.

The next three values are as follows:

54(3)=162\\162(3)=486\\486(3)=1458

The value in dollars,v(x),of a certain truck after x years is represented by the equation v(x)=32,500(0.92)^x.To the nearest dol
Vika [28.1K]

Answer: $2193

Step-by-step explanation:

v(x) = 32,500(.92)^{x}

Plug two and three in for x

v(2) = 32,500(.92)^{2}

v(2) = 32,500(.8464)

v(2) = 27,500

v(3) = 32,500(.92)^{3}

v(3) = 32,500(.778688)

v(3) = 25,307.36

Subtract v(3) from v(2)

27,500 - 25,307.36 = 2192.64

Round to the nearest dollar to get $2193

Fraction form: \frac{89}{99}

Step-by-step explanation:

0.89898989.... is the correct answer because it can be written as \frac{89}{99} in the simplest form. and 0.89898989.... is rational because it is a repeating number.

Any rational number is a number that can be written as a fraction, a repeating decimal, a whole number, an integer, etc. As long as the number is a number with infinite digits like π.

There are 650 sixth graders in the school and 338 of them are girls. What percent of the 6th grade students are girls?
Evgesh-ka [11]

Answer:

52% are girls

Step-by-step explanation:

We know that there are 650 sixth-graders and 338 of them are girls, we are then asked to find the percentage of how many are girls.

We have the fraction 338 over 650 but need to reduce it.

To solve this, we need to find the GCF of 650 and 338, which is 26, so divide both the numerator and denominator by 26.

\frac{338/26}{650/26}

\frac{13}{25}

Now divide the 13 and 25 :

13 / 25 = 0.52

0.52 * 100 = 52%

Therefore, 52% of the sixth-graders in the school are girls
