(_+10)(_+-1)= 11x^2+17x-10 in factored form

Mathematics
1 answer:
Sever21 [200]3 years ago
4 0

Answer:

The factored form will be:

11x^2+17x-10=\left(11x-5\right)\left(x+2\right)

Step-by-step explanation:

Given the expression

11x^2+17x-10

Breaking the expression into groups

=\left(11x^2-5x\right)+\left(22x-10\right)

  • factoring out x from 11x²-5x

11x²-5x = x(11-5)

  • factoring out 2 from 22x-10

22x-10 = 2(11x-5)

so the expression becomes

=x\left(11x-5\right)+2\left(11x-5\right)

factoring out common term 11x-5

=\left(11x-5\right)\left(x+2\right)

Therefore, the factored form will be:

11x^2+17x-10=\left(11x-5\right)\left(x+2\right)

A survey of 2,000 doctors showed that an average of 3 out of 5 doctors use brand X aspirin. How many doctors use brand X aspirin
VladimirAG [237]
This is a proportion problem that involves cross-multiplication
Set your problem up like so:
\frac{x}{2,000} = \frac{3}{5}

Now cross multiply
2,000 x 3 = 6,000
now you're left with 5x = 6,000
Now divide by 5 on both sides
Answer is 1,200

Which value of m will create a system of parallel lines with no solution? y=mx-6 8x-4y=12 A coordinate grid with one line labele
nydimaria [60]

Answer:

A system of parallel lines will be created where the two lines will never meet and have no common solution at a value of m = 2

Step-by-step explanation:

The equation of the given line is 8·x - 4·y = 12

Which gives;

8·x- 12= 4·y

y = 2·x - 3

Given that the line passes through the points (0, -3) and (1, -1), we have;

Slope, \, m =\dfrac{y_{2}-y_{1}}{x_{2}-x_{1}}

When (x₁, y₁) = (0. -3) and (x₂, y₂) = (1, -1), we have;

Slope, \, m =\dfrac{(-1)-(-3)}{1-(0)} = 2

y - (-3) = 2×(x - 0)

y = 2·x - 3 which is the equation of the given line

For the lines 8·x - 4·y = 12, which is the sane as y = 2·x - 3 and the line y = m·x  - 6 to have no solution, the slope of the two lines should be equal that is m = 2

Given that the line passes through the point (1.5, 0), we have;

y - 0 = 2×(x - 1.5)  

y = 2·x - 3...................(1)

For the equation, y = m·x  - 6, when m = 2, we have;

y = 2·x  - 6..................(2)

Solving equations (1) and (2) gives;

2·x - 3 = 2·x  - 6, which gives;

2·x - 2·x=  - 3 - 6

0 = 9

Therefore, a system of parallel lines will be created where the two lines will never meet and have no common solution at a value of m = 2.

How to find the missing unit 18/3=?/1
Gennadij [26K]

Answer:

x = 6

Step-by-step explanation:

<u>Step 1:  Cross Multiply</u>

<u />\frac{18}{3} = \frac{x}{1}

18 * 1 = x * 3

18 = 3x

<u>Step 2:  Divide both sides by 3</u>

<u />18/3 = 3x / 3

6 = x

Answer:  x = 6
