You can factor it to find the answer:

<span>–3x^2 + 4x + 4 
</span>–(3x^2 - 4x - 4)
–(3x + 2)(x - 2)

x=-2/3 or 2, which means that there are  x intercepts, at -2/3 and 2.

Y = -3x^2 + 4x + 4

Educated guess: There may be about 2 x - intercepts in the equation.

The sum of the following algebraic expression 2x + 15, 7-8x and 3x - 41 is 30 find the value of x..​
Ksju [112]

\\  \tt  \longmapsto2x + 15 + 7 - 8x + 3x - 41 = 30 \\   \\  \tt  \longmapsto 2x - 8x + 3x + 15 + 7 - 41 = 30 \\  \\  \tt  \longmapsto  - 3x - 19 = 30 \\  \\  \tt  \longmapsto 3x + 19 =  - 30 \\  \\  \tt  \longmapsto 3x =  - 30 -19 \\  \\  \tt  \longmapsto 3x =  - 49 \\  \\  \tt  \longmapsto x = - \frac{49}{3}

Darla spent $120.37 on groceries in January, $108.45 in February, and $114.86 in March. What was the average monthly cost of Dar
kari74 [83]
In order to find an average, you have to add all the numbers and divide by the number of things you added.

120.37 + 108.45 + 114.86 = 343.68
343.68/3 = 114.56

She spent an average of $114.56 each month on groceries.

PLEASE ANSWER QUICKLY!!The diameter, D, of a sphere is 10.4 mm. Calculate the sphere's volume, V.
Svetlanka [38]

Answer:

About 588.7 mm^3

Step-by-step explanation:

The formula for the volume of a sphere is (4/3)*pi (or in this case 3.14)*r^3, where r is the radius.

We need the radius. We are given the diameter, 10.4.

The radius is half the diameter, so 10.4/2=5.2.

Use r=5.2 and put it into the formula:

(4/3)*3.14*5.2^3≈588.7
