Which value of "X" is a solution to this equation? 4x2 +22x +10

Mathematics
1 answer:
Maslowich2 years ago
5 0

Answer:

Two solutions: X = -5 and X = -0.5

Step-by-step explanation:

4x^2 + 22x + 10 = 0 // divide by 2

2x^2 + 11x + 5 = 0

delta = 11^2 - 4 * 2 * 5 = 121 - 40 = 81

sqrt(delta) = 9

x1 = (-11 - 9) / 4 = -5

x2 = (-11 + 9) / 4 = -0.5

Write the equation of a line that is perpendicular to the line that passes through (4,−3)and (−7,8).
masha68 [24]

Line perpendicular to a given line is = 1/m

To find m, use m =y2-y1/x2-x1 formula

m = (8-(-3))/(-7-4)

m = 11/-11,

m = -1

Use y= mx+c to find equation of line

Plug in a pair of values,

-3= -1(4)+ c

c= 1

Thus, equation is:

y = -x+1

Equation of line perpendicular to this line is:

y= x+1

What is algebra? What do you do with algebra?
tigry1 [53]

Algebra is a very important branch of math.

Algebra is a lot like arithmetic which means it follows all the rules of arithmetic, and it still uses the four main operations that arithmetic is built on.

In arithmetic, the only thing that was unknown was the answer to the problem. For example, 39 + 2 = 41.  In algebra, we use a variable to represent the number. A variable is a letter that represents any number. The most common variable is "x".
