NEED HELP ASAP!!!! What is the discriminant of 3x^2-10x=-2^2

Mathematics

Natali5045456 [20]3 years ago
3 0

Answer:

52

Step-by-step explanation:

3x^2-10x=-2^2      Rearranging:-

3x^2 - 10x + 4 = 0

Discriminant = b^2 - 4ac  ( for ax^2 + bx + c = 0) =

(-10)^2 - 4 * 3 * 4

= 100 - 48

= 52

Which number-line model represents the sum of 1.25+(-0.75)?
SIZIF [17.4K]

Solution:

<u>A few tips...</u>

  • Tip-1: If "+" and "-" are multiplied, it gives a result of "-".
  • Tip-2: If "-" and "-" are multiplied, it gives a result of "+".
  • Tip-3: If "+" and "+" are multiplied, it gives a result of "-".

<u>Changing the sign of the given equation.</u>

  • 1.25 + (-0.75)
  • => 1.25 - 0.75                                        [Sign changes according to tip-1.]

This could only mean that the arrow would go to <u>1.25 units forward.</u> Then a second arrow will be drawn to go <u>0.75 units back.</u>

The graph that matches with the above info is Option C.

Find the slope of the line containing the pair of points f(1) = -6 and f(-7) = -6.
DENIUS [597]

We have that    the slope of the line containing the pair of points f(1) = -6 and f(-7) = -6. is

m=\infty

From the question we are told

Find the slope of the line containing the pair of points f(1) = -6 and f(-7) = -6.

Where Standard form of Equation is

y=mx+c

Generally the equation for the Slope  is mathematically given as

m=\frac{y_2-y_1}{x_2-x_1}

Therefore

m=\frac{-7-1}{-6-(-6)}\\\\ m= \infty

Therefore

The slope of this line is

m=\infty

Pachacha [2.7K]
3n=27+3
you can do anything as long as you do it to both sides
3n=27+3
add like terms
27+3=30
3n=30
divide both sides by 3
n=10
