2xsquared +3x+1=0 solve using quadratic formula

Mathematics
1 answer:
vlada-n [284]3 years ago
5 0

Answer:

<em>x</em> = \frac{1}{2} , -1

Step-by-step explanation:

The quadratic formula is:  <u>-b±√b²-4ac</u>

                                                 2a

The discriminant (Δ) is b²-4ac. Evaluating this expression after substituting for <em>a, b </em>and <em>c</em> helps you identify the number of real solutions to the quadratic equation.

<em>a </em>= 2, <em>b</em> = 3, <em>c </em>= 1

Δ = -3²- 4 x 2 x 1;

Δ = 1

<u>-3±1 </u>

Write an equation in point-slope form for the line.<br> (1,3) <br> (0,1)<br> m=4
Anna [14]

Given coordinates (1,3) and (0,1).

In order to find the equation of line, we need to find the slope between given coordinates.

We know slope formula,

m= \frac{y2-y1}{x2-x1}

We have (x1,y1) = (1,3) and (x2,y2) = (0,1).

Plugging values of x1,y1,x2 and y2 in slope formula, we get

m=\frac{1-3}{0-1}

Simplifying top and bottom of the fraction we got for slope

m=\frac{-2}{-1}=2

We got slope m=2.

We are given second point (0,1), where x-coordinate is 0 and y-coordinate is 1.

y-intercept is a point on y-axis, where x=0.

Therefore, y-intercept = 1.

Now, applying slope-intercept form of the linear equation

y=mx+b, where m is the slope and b is y-intercept.

m=2 and b=1.

Plugging values of m and b in slope-intercept form, we get

y=2x+1.

Therefore, point-slope form for the line is y=2x+1.

A clothing store offers a free T-shirt when a customer spends $75 or more. Lyndon has already spent $36. 95. Which statement bes
Allisa [31]

Lyndon should spend $38.05 or more to get a free T-shirt.

We have to find the statement best represents all of the amounts he can spend to get a free T-shirt

Suppose that the amount Lyndon get free T shirt is x.

Given that a clothing store offers a free T-shirt when a customer spends $75 or more.

Lyndon has already spent $36.95.

x+36.95\geq 75

To find the value of x,

Solve above inequality

x\geq 75-36.95

x\geq 38.05

Therefore,

Lyndon should spend $38.05 or more to get a free T-shirt

creativ13 [48]

Answer:

<h2><u><em>x = -18</em></u></h2>

Step-by-step explanation:

X=20=-x+2 can you solve this?

assuming that the equation is:

20 = -x + 2

x = -20 + 2

x = -18
