You need 2 points in order to draw this first put x=0 and you will find y= - 4 then solve
0 =  - (3 \div 4)x - 4

A flowerbed is to be 3m longer than its width.the flowerbed will have an area of 70m²​
melomori [17]
ANSWER
Yes, it is a quadratic equation which is x² + 3x - 70 = 0

SOLUTION

Area = Length × Width
Let x be the Length, L = x
Length is 3 cm longer than its width, thus, W = x + 3
The Area is equal to 70m², thus, A = 70m²

In Mathematical representation,
A = L × W
70 = (x)(x + 3)
70 = x(x) + x(3)
70 = x² + 3x
0 = x² + 3x - 70

How do you graph x+2÷(x^2-3x-10) without a calculator?
ahrayia [7]
First step is to simplify the equation into a form that we are familiar with graphing, in this case the simplest way i believe is to factorise the denominator. There are many methods of factorising quadratics but in this case my preferred method would be as follows:

x^2-3x-10, because it is a quadratic equation we know it can be factorised into the form (x+a)(x+b), we know that -10 is the product of a and b, therefore a and b can only be +/-1 and -/+10, or +/-5 and -/+2, the next step is to see which of these factors sum to equal -3, in this case it will be +2 and -5, therefore x^2-3x-10 can be factorised into (x+2)(x-5).

We have now simplified the function into f(x)= (x+2)/(x+2)(x-5), we can still simplify the function further though:

(x+2)/(x+2)(x-5), the numerator and denominator have a common factor therefore we can divide the numerator and the denominator by that factor, ((x+2)/(x+2))/((x+2)(x-5)/(x+2))= 1/(x-5) 

The function is now in it's simplest form, so we will now graph it. As a side note you can't perfectly "graph" any function by hand so instead we will sketch the function, to sketch a function you need to know the general shape of the function  and any x/y intercepts or asymptotes.        

Functions of the form a/(bx+c) are reciprocal functions, you need to be able to remember what reciprocal function looks like to be a able to sketch them by hand, they look something like this https://www.desmos.com/calculator/df2wiewhsz. To work out the x-intercept we will assign f(x) as 0, 0=1/(x-5), multiply both sides by (x-5), (x-5)0=1, 0=1, 0 doesn't equal 1 therefore there is no x-intercept but instead there is an asymptote at y=0. To work out the y-intercept we will assign x as 0, f(x)=1/(x-5), f(x)=1/-5, therefore the only y-intercept is at coordinates (0.-0.2). All reciprocal functions have 2 asymptotes, we have already found one of them, by making f(x)=0, to find the other asymptote we will make 1/(x-5)=∞, 1/0=∞, therefore x-5 has to equal 0, therefore the second asymptote will be x=5.

after putting all of this together the graph should look something like this https://www.desmos.com/calculator/bibeeu7xtv

Delvig [45]

Answer:

x=2/3+1/3\sqrt{10}

Step-by-step explanation:

Let's solve your equation step-by-step.

3x2−4x−2=0

For this equation: a=3, b=-4, c=-2

3x2+−4x+−2=0

Step 1: Use quadratic formula with a=3, b=-4, c=-2.

Mrs. R is pregnant and very worried that the child will have beta-thalassemia. What is the probability that the child will have
kenny6666 [7]

Answer:

There are three kind of beta-thalassemia.

Total possible outcome=  3 types of beta- thalassemia + 1 [child will have no trace of disease] = 4

As we know Probability(outcome) = \frac{\text{ Total favorable outcome}}\text{Total possible outcome}

Probability that the child will have beta-thalassemia major =\frac{_{1}^{3}\textrm{C}}{_{1}^{4}\textrm{C}}

     =\frac{3}{4}

   ∴ favorable=_{1}^{3}\textrm{C}

 And , Total =_{1}^{4}\textrm{C}

Probability that the child will have no trace of the disease=\frac{1}{4}
