How many real numbers solutions are there to the equation? 0= -3x^2+x-4

Mathematics

Nataly_w [17]3 years ago
4 0
<span>ax^2+bx+c=0
The quadratic formula is
x=(-b+/-</span><span>√(b^2-4ac))/2a
The part </span>√(b^2-4ac) tells us how many solution we will get:
using <span>-3x^2+x-4
</span>√(1-4(-4)(-3))=√(1-36)=√-35 this is an impossible result since the inside of a square root has to be always greater or equal to zero. This means that the equation has no solutions.

Help! Best answer gets brainliest
julsineya [31]

Answer:

7.9

Step-by-step explanation:

the first thing to do is find the second projection.

16-7 = 9

than we can use a proportion to find BD

7 : BD = BD : 9

BD = √9 x 7 = √63 = 7.9

we have to use the square root because in the proportion BD Is repeated two times. If we don’t use it, we find BD^2

For what value of a does (1/9)a+1 =81a+1 272-a?
AlexFokin [52]

Answer:

-4

Step-by-step explanation:

\left( \dfrac{1}{9}\right)^{a+1}= 81^{a+1}\cdot 27^{2-a}\\\\\\(3^{-2})^{a+1}=(3^4)^{a+1}\cdot (3^3)^{2-a} \\\\\\3^{-2a-2}=3^{4a+4}\cdot 3^{6-3a} \\\\\\3^{-2a-2}=3^{a+10} \\\\\\-2a-2=a+10 \\\\\\-3a=12 \\\\\\a=-4

Hope this helps!
