Answer:

The factor form of the given equation is 6x^2-13x-5=(2x-5)(3x+1)                                    

Step-by-step explanation:

Given : Expression 6x^2-13x-5

To find : Which expression represents the factored form of given expression?

Solution :

We have given the quadratic equation,

6x^2-13x-5=0

We solve the given quadratic equation by middle term split,

i.e. the multiple of number is 30 and addition is -13,

6x^2-15x+2x-5=0

Taking common to form factor,

3x(2x-5)+1(2x-5)=0

(2x-5)(3x+1)=0

Therefore, The factor form of the given equation is 6x^2-13x-5=(2x-5)(3x+1)

Do these tables of values represent linear functions or nonlinear functions?
KIM [24]

Answer:

1. Nonlinear

2. Nonlinear

3. Linear

Step-by-step explanation:

Hello there!

To solve this question, let's figure out a ratio of how much an x variable goes up by how much the y goes up. If it is a linear function (meaning a straight line), this ratio should stay consistent throughout the whole data plot.

For the first one, we can see that x is going up by 1, and so is y. But on the second to last, it jumps up once on the x value by 1, but y went up by two. This is not a consistent ratio and is considered nonlinear.

For the second one, we can see that for every x value going up 1, the y goes up by 1 too, as seen between the transition from the x values 1 to 2. However, when it goes from 2 to 4, the correct y value, if linear, should be 5.8. This is nonlinear.

The last one says that when x goes up by one, y value decreases by 2. this stays consistent all around and is linear.

At a rally attended by 520 people, 30% were fantes, 25% were ewes, 15% were nzemas, 20% were gas and the rest were gonjas. How m
mariarad [96]

Answer:

No. of gonjas = 52

No. of more nzemas than fantes = 78

Step-by-step explanation:

Total no. of people = 520

No. of fantes = \frac{30}{100} × 520

No. of fantes = 156

No. of ewes = \frac{25}{100} × 520 = 130

No. of nzemas = \frac{15}{100} × 520 = 78

No. of gas = \frac{20}{100} × 520 = 104

No. of gonjas = 520 - (156 + 130 + 78 + 104) = 52

No. of fantes = 156

No. of nzemas = 78

No. of more nzemas than fantes = 156 - 78 = 78

Pie chart of the following problem is shown below.

If f(x)=x2+2x−5 and g(x)=2x+4, what is(f⋅g)(x)?
kvasek [131]
(F.g)(x)= (x^2+2x-5)(2x+4)

(F.g)(x)= 2x^3+4x^2+4x^2+8x-10x-20

(F.g)(x)= 2x^3+8x^2-2x-20=> C
