From the numbers between 11 and -14
Number of terms: 6
First term: -14
6th term = 11
a + (n-1)d = -14
11 + (6-1)d = -14
11 + 5d = -14
5d = -25, d = -5

From 11 you subtract 5 to the left
d = 6, c = 1, b = -4, a = -9

Which is the smallest non-negative?

Solution: c

Solve using substitution x = 3y + 1 2x + 4y = 12​

Answers

Answer:

x = 4

y = 1

Step-by-step explanation:

x = 3y + 1 (Multiply everything by -2)

2x + 4y = 12​ (Transfer 4y to the right of the = sign)

2x = -4y + 12

-2x = -6y - 2

0 = -10y + 10

-10 = -10y

y = 1

x = 3y + 1

x = 3(1) + 1

x = 3 + 1

x = 4

Graph this function: y =3/4x - 4 (you can just put the cordinants)​

CAN SOMEONE HELP ME WITH THIS PLEASE?

Answers

Answer:

Y= 4   and    X=2

Step-by-step explanation:

When you are trying to find the X or Y value for an equation, set the opposite value to zero. That means that if you are trying to find Y in 6x+3y=12, you would make the X zero. Since six is being multiplied by X and X now equals zero, your equation for finding the Y value is now 3y=12. Divide them both by three and you get Y=4. In order to find your X value you would do the same thing. Since you are trying to find X, set the Y value to zero. That makes your equation for finding the X value 6x=12. That is because, again, you set Y to zero, and three times zero is zero. 6x=12 equals X=2 because you divide both sides by 6.

Ste-by-step explanation:

Three sides of a quadrilateral are the same length, g, The length of the fourth side is 7 inches,
The perimeter of the quadrilateral is 10 inches,
Write an equation that represents
the situation
7
3
7

Answers

Answer:

Step-by-step explanation:

Let s represent the length of each of the three sides mentioned.  The length of the fourth side is 7 inches.  Adding the lengths of the four sides together yields 10 inches:  g + g + g + 7 = 10 (inches)

Then 3g + 7 = 10, or 3g = 3, or g = 1.  

This equation is OK, but there's no solution, since 3g or just 3 is less than 7.  With side lengths 1, 1, 1, 7, we cannot draw a quadrilateral.

The coach of a lacrosse team bought ice cream cones to celebrate a victory. A single-scoop cone was $3 and a double-scoop cone was $5. The coach bought 15 cones and paid $57. A system of equations describing this situation could be written in the form below where s represents the number of single cones and d represents the number of double cones. What is the sum of A, B, C and E?

Answers

Answer:

The number of

Single scoop cones = s = 9

Double scoop cones = d = 6

Step-by-step explanation :

Let t he number of

Single scoop cones = s

Double scoop cones = d

A single-scoop cone was $3 and a double-scoop cone was $5. The coach bought 15 cones and paid $57.

The system of equation

= s + d = 15.. Equation 1

s = 15 - d

3s + 5d = 57.... Equation 2

We substitute 15 - d for s

3(15 - d) + 5d = 57

45 - 3d + 5d = 57

Collect like terms

- 3d + 5d = 57 - 45

2d = 12

d = 12/2

d = 6

Solving for s

s = 15 - d

s = 15 - 6

s = 9

Therefore,

The number of

Single scoop cones = s = 9

Double scoop cones = d = 6

An environmentalist tracks the total number of trees y in a park after x years of a planting program. The line of best fit for the data is represented by the equation y = 3x + 15. What is the percent change in the total number of trees from x = 4 to x = 7? Round your answer to the nearest percent.

Answers

Answer:

33.33%

Step-by-step explanation:

The line of best fit for the data is represented by the equation y = 3x + 15.

At x = 4,

y = 3(4) + 15 = 27

At x = 7,

y = 3(7) + 15 = 36

We need to find the percent change in the total number of trees from x = 4 to x = 7.

So,

[tex]\%=\dfrac{36-27}{27}\times 100\\\\=33.33\%[/tex]

So, the required percentage change is equal to 33.33%.
