(6x2 - 2x) + (5x-7)
A. 30x3 - 52x2 + 14x
B. 6x2 - 7x+7
c. 11x2 - 9x
D. 6x2 + 3x - 7
​

Answer:

(-1, 3)

Step-by-step explanation:

In order for a point to be a solution to a system of equations, the lines have to intersect at that point in the graph. We can see that the two lines at the graph intersect at (-1,3), so that must be the solution.  

Answer:

$4.3

Step-by-step explanation:

Cole bought 10 gallons of gas at the gas station with the lowest price.(the lowest price is $3.57 each gallon.) He paid with two $20 bills. Write and solve an equation to find his change.

two $20 bills = 2 * $20

= $40

Gallons of gas = 10

Lowest price of each gallon = $3.57

Cost of 10 gallons of gas = 10 * $3.57

= $35.7

Let his change = x

His change = Amount paid with - cost of gas

x = $40 - $35.7

x = $4.3

His change = $4.3

Answer:

Step-by-step explanation:

Answer:

x = ±1.155

Step-by-step explanation:

We need to graph the given function [tex]f(x) = 6x^2-11+3[/tex] and find its zeroes.

The attached figure shows the graph of the given function.

To find zeroes,

Put f(x) = 0

So,

[tex]6x^2-11+3=0\\\\x=\pm 1.155[/tex]

Hence, this is the required solution.

Answer:

1

Step-by-step explanation:

Answer:

1) no, it is not a right triangle.     3² + 4² ≠ 25²

2) no, it is not a right triangle.    38² + 77² ≠ 86²

3) no, it is not a right triangle.    10² + 36² ≠ 37²

4) yes, it is a right triangle.        30² + 40² = 50²

5) yes, it is a right triangle.         8² + 15² = 17²

6) yes, it is a right triangle.        18² + 24² = 30²

7) no, it is not a right triangle.     5.3² + 7.9² ≠ 8.1²

8)  yes, it is a right triangle.         10² + 24² = 26²

Answer:

27 degrees

Step-by-step explanation:

So looking at this rhombus, we can make out 4 seperate traingles.

How many degrees are in a traingle? 180.

Looking at the traingle with z angle in it, we can see that it is a right traingle.

Now, lets subtract that 90 degrees from the 180.

This leaves us with the 63 degrees and x that make up the 90 degrees that are left.

Now all we have to do is subtract the 63 degrees from the 90 total degrees that we have left, and we will find out what z is equal to.

90 minus 63 is 27, so the angle of z is:

27 degrees

I hope this helps!

Note that I assumed these are right traingles, however I dont see how you can solve this without these being right trianlges, since you cannot use sin, cos, or tan to find this value without another angle or side length.

b) 19.426 peri, 26.139

Answer :

The system can be inconsistent or consistent and  independent or consistent and  dependent.

Step-by-step explanation :

Consistent system: When the system of equation have atleast one solution then the system is consistent.

Inconsistent system: When the system of equation have no solution then the system is called inconsistent.

Dependent system: When the consistent system have infinite number of solutions then the system is called dependent.

Independent system: When the consistent system has exact one solution then the system is called independent system.

We are given two solutions of two equations are (3,2,-6) and (-2,5,1).

But the system of equations have three equations.

Then, the system of equations may have no solution or may have altleast one solution.

If given system of equations have no solutions then the system is inconsistent.

If the given system of equations have two or more than two solutions then the system is consistent and dependent.

If the given system of equations has exactly one solution then the system is consistent and independent.

The system can be inconsistent or consistent independent or consistent independent.

Answer:

3x-8

Step-by-step explanation:

15x^2 - 22x - 48 / 5x + 6

15x^2 / 5x = 3x

-48 / 6 = -8

3x-8

Hope this helps :)

Answer:

The answer is G. The first part of the segment is 7 (between 6 and 8) and the endpoint is at 20. It has a range of 13.

Step-by-step explanation:

since y=6x

by substitution

-5x+ 2 (6x)= -42

-5x+ 12x=-42

7x= - 42

divide both sides by 7

x= 6

y=6x

y =6*6

y=36

Answer:

k = -2

Step-by-step explanation:

firstly, let us examine the kind of transformation that we have

We have a transformation from (3,2) to (3,0) and (-3,0) to (-3,-2)

So, we are actually subtracting 2 from the values of f(x) to get the values of g(x)

This shows a vertical translation to the tune of 2 units in the downward direction

So, the correct answer here is that -2 is being subtracted from f(x) to give g(x)

Accordingly, the value of k in the question is -2

Answer:

21

Step-by-step explanation:

I think its 21, because the BD line divides the big triangle into 2 ones and they are equilateral triangle, sorry if I'm wrong

Answer:

BD = 21

Step-by-step explanation:

The sector divided AC into two equal pieces and since this is a right triangle the height of the triangle BD is equal to half of the base

(21+21) / 2 = x

42 / 2 = x

21 = x

Answer:

The area of this triangle is 7.5 square feet.

Step-by-step explanation:

Area of a triangle formula: A = 1/2 * base * height;

Apply formula to equation

(5 * 3)/2 = 7.5
