Answer:

x= 1/3 or x=4

Step-by-step explanation:

Let's solve your equation step-by-step.

3x2−13x+4=0

Step 1: Factor left side of equation.

(3x−1)(x−4)=0

Step 2: Set factors equal to 0.

3x−1=0 or x−4=0

x= 1/3or x=4

Answer:

Step-by-step explanation:

The y-intercept is 10 of the line that passes through the points (2,7) and (6,1).

The equation of a line is found using the slope-intercept form of a straight line. We need to know the slope of the line and the intercept where the line crosses the y-axis in order to use the slope-intercept formula. Consider a straight line with y-intercept b and slope m. For a straight line with slope "m" and y-intercept "b," the slope intercept form equation is: y = mx + b.

Given that the points are (2,7) and (6, 1).

To find the equation, using the slope formula;

m = (y₂ - y₁) / (x₂ - x₁)

m = (1 -7) / (6-2)

m = -6/4

m = -3/2

Now to find the slope intercept form,

y = (-3/2)x + b,

here b is the y-intercept.

Now we will substitute the value of (2,7) in the slope intercept equation.

Hence, b = 10

Therefore, the y-intercept is 10 of the line that passes through the points (2,7) and (6,1).

Answer:

17:14 or 17 to 14

Step-by-step explanation:

since you know there are 14 girls, subtract 14 from 31 and then you'll get 17. since its asking for a ratio of boys to girls not girls to boys, you put boys first, then girls. so your answer will be 17:14

Answer:

Step-by-step explanation:

The slope formula is (change in y)/(change in x)

since the numerator (change in y) is 0, the slope will be 0

Answer:

9 runners

Step-by-step explanation:

Number of runners who started race = 45

Fraction that dropped off in the first half =. 2/3

Fraction of the remaining that dropped of in the second half = 2/5

Number of runners who dropped off in the first half :

(2/3) * 45 = (2 * 45) / 3 = 90 /3 = 30 runners

Runners left = (45 - 30) = 15

Number who dropped off in the second half :

(2/5) * 15 = (2 * 15) / 5 = 30 /5 = 6 runners

Number of runners who finished the race :

(15 - 6) = 9 runners

Answer:

c= 89

Step-by-step explanation:

the angles of a triangle add up to 180

in this triangle, our angles are:

c-33

c-25

c-29

this means that

(c-33) + (c-25) + (c-29) = 180

3c - 87 = 180

add 87 to both sides

3c = 267

divide both sides by 3

c = 89

Well, we know standard form of quadratic equation : ax² + bx + c where,

a = Coefficient of x²

b = Coefficient of x

c = Constant term

We also equation for determinant :

⇒ b² - 4ac

Here, if value of determinant i.e. (b² - 4ac) = A perfect Square, then we can understand that the givdn equation is factorisable.

But, if the value of (b² - 4ac) ≠ A perfect square, then it will be considered as "Not factorisable"

Now let's calculate whether the equation is factorisable or not :

Comparing the given equation with ax² + bx + c, we get :

a = 1

b = -3

c = -54

Putting values in the determinant equation :

⇒ (-3)² - 4(1 × -54)

⇒ 9 + 216

⇒ 225

⇒ 15²

So, determinant = A perfect square

That means the given equation is factorisable.

Now let's factorize with by middle term splitting :

⇒ x² - 3x - 54

⇒ x² -(9 - 6)x - 54

⇒ x² - 9x + 6x - 54

⇒ x(x - 9) + 6(x - 9)

⇒ (x + 6)(x - 9) [Required Solution]

Hence, we get our required solution.

Step-by-step explanation:

The pencils and the notebook together cost $2.75, from there you can calculate how many erasers.

1 eraser would bring the total to $3, therefore Denise can buy $1.25 more of erasers which is 5. 3 + 1.25 is $4.25. therefore Denise can buy 6 erasers

Answer:

he can buy 6 erasers

Step-by-step explanation:

because if you add 1.75 plus one and add 0.25 ....6 times it will equal 4.25 i hope this was helpful

3.2 plz help me to

Step-by-step explanation:

Answer:

3.2

Step-by-step explanation:

Let Cesar's, Carmen's and Dalila's amount be represented by x, y and z respectfully.

Since they're money sum up to $95.34, the first expression will be;

x+y+z=95.34

Carmen_y_ is $12.12 less than cesar_x, so the equation will be ;

y=x-12.12

Cesar_x_raised $35more than Dalila_z. So the equation will be;

x=z+35

making z the subject, z=x-35 .

Substituting the Second equation into the first one, we get;

x+x-12.12+z=95.34

Subtracting the third equation into the new equation we get;

x+x-12.12+x-35=95.34

Simplifying, we get 3x- 47.12= 95.34.

3x=142.46
