Rewrite the equation 8x + 6x^2 -7=x^2 in standard form and identify a, b, and c.
Vladimir79 [104]

Answer:

5x^2+8x-7=0\\a=5\\b=8\\c=-7

Step-by-step explanation:

The standard form of a quadratic is ax^2+bx+c=0. You need to subtract the x^2 from the right to set the quadratic equal to 0. Then a,b, and c are equal to the values of the coefficients in front of the terms.

If this helped, a brainliest would be greatly appreciated!

What is the value of x in the equation 2(x – 3) + 9 = 3(x + 1) + x?<br>x = <br>​
sukhopar [10]

Start with

2(x-3)+9=3(x+1)+x

Expand both parentheses by multiplying both terms by the number outside:

2x-6+9 = 3x+3+x

Sum like terms:

2x+3 = 4x+3

Simplify the "+3" on both sides:

2x = 4x

Subtract 2x from both sides:

2x=0

Divide both sides by 2:

x=0

Sheri is making 4 pounds of mixed nuts. She will use One-third the amount of macadamia nuts as she does almonds. A graph titled
notsponge [240]

1 pound of macadamia nuts; 3 pounds of almonds of each nut will she use.

Given that,

Sheri is making 4 pounds of mixed nuts.

She will use One-third the number of macadamia nuts as she does almonds.

A graph titled Sheri's mixed nut recipe has pounds of macadamia nuts on the x-axis, and pounds of almonds on the y-axis. 2 lines intersect at (1, 3).

We have to find,

How many pounds of each nut will she use?

According to the question,

Total mixed nuts are 4 pounds,

She will use One-third the number of macadamia nuts as she does almonds.

2 lines intersect at (1, 3).

Therefore,

Sheri's mixed nut recipe has pounds of macadamia nuts on the x-axis,

At x-axis, the point 1 lies.

So, macadamia nuts have 1 pound.

And pounds of almonds on the y-axis,

At y-axis, the point 3 lies.

So, almond nuts have 3 pounds.

Hence, 1 pound of macadamia nuts; 3 pounds of almonds of each nut will she use.

Rewrite the expression with a perfect square: x^2 - 14x + 11
nikitadnepr [17]

   Factoring  x2-14x+11 

The first term is,  x2  its coefficient is  1 .

The middle term is,  -14x  its coefficient is  -14 .

The last term, "the constant", is  +11 

Step-1 : Multiply the coefficient of the first term by the constant   1 • 11 = 11 

Step-2 : Find two factors of  11  whose sum equals the coefficient of the middle term, which is   -14 .

     -11   +   -1   =   -12     -1   +   -11   =   -12     1   +   11   =   12     11   +   1   =   12

Observation : No two such factors can be found
