Answer:

x=0.450765 or x=−0.950765

Step-by-step explanation:

14x² + 7x - 6

→ Find the product, sum and factors

Product = -6

Sum = 7

Factors = No factors

→ Since there are no factors utilise the quadratic formula

\frac{-b+-\sqrt{b^{2}-4ac } }{2a}

→ List the values of a, b and c

a = 14

b = 7

c= -6

→ Substitute into the formula

\frac{-7+-\sqrt{7^{2}-4*14*-6} }{2*14}

→ Simplify

x=0.450765 or x=−0.950765

Answer:

x=0.950 or -0.450

Step-by-step explanation:

14x^2+7x-6

using quadratic formula

x=-b+√b^2 -4ac/2a or x= -b-√b^2-4ac/2a

where b;7 ,a;14, c;-6

x=-7+√7^2-4(14)(-6)/2(14)

x=7+√49+336/28 or 7-√49+336/28

x=7+√385 /28 or 7-√385/28

x=7+19.621 /28 or 7-19.621 /28

x=26.621/28 or -12.621/28

x=0.950 or -0.450

Drupady [299]
No unit fractions are shown. (Sometimes editing is required when you copy and paste your question text.)

Selections B and D have 1 as their first digit. We suspect those are supposed to be the unit fractions 1/8 and 1/3, respectively.

If c is a positive integer, how does the graph of y=x+c compare to the graph of y=x?
Len [333]

Answer:

It is shifted c units to the left  .

Step-by-step explanation:

In general, adding a constant c to the value of x shifts a graph c units to the left.

The graph of y = x + c is parallel to y = x,  the y-intercept becomes (0, c) and the x-intercept becomes (-c, 0).

In the diagram below, the red line is the graph of y = x, and the blue line is the graph of y = x + 1.

Please help me by solving this!​
JulsSmile [24]

Answer:

Ani age is 21

Biju age is 18

Step-by-step explanation:

let Ani age be X

let Biju age be Y

the difference of their age is 3

i.e X - Y = 3......,....(equ. 1)

let Dharam age be A

let Cathy age be B

i.e A = 2x

B = y/2

the difference of their age is 30

Y/2 - 2x = 30..... (equ. 2)

from equ.1 X = ( 3+y).........( equ.3)

y/2 - 2(3+y) = 30

y/2 - 6 + 2y = 30

multiply both side by 2

y - 6 + 2y = 60

y + 2y = 60 - 6

3y = 54

Y = 18

from equ.3

X = 3+Y where y is 18

X = 3+18 = 21

Will someone help me with both of these I have to solve for the unknown portions please
IceJOKER [234]

Answer:

b=2.5

p=6

Step-by-step explanation:

Take the fraction and simplify it. So 10/8 would be 5/4

You multiply the 2 by 2, giving you h/4

So now you have 5/4=h/4

h=5 but now you have to divide both by 2 again so it can go back to the original fraction.

5÷2=2.5 and 4÷2=2

Second Problem! 4/2 is equal to 2/1

You can also multiply 4 by 3 to get the numerator as 12. Multiply the 4 by 3 and the 2 by 3

Now you have 12/6= 12/p

So p is 6
