The solutions of x are 1 and ![-\frac{5}{2}](https://tex.z-dn.net/?f=-%5Cfrac%7B5%7D%7B2%7D)
Step-by-step explanation:
Given,quadratic equation is
![2x^2+3x-5=0](https://tex.z-dn.net/?f=2x%5E2%2B3x-5%3D0)
[
here a =2, b= 3 and c= -5]
![\Leftrightarrow x = \frac{-3\pm\sqrt{49} }{2.2}](https://tex.z-dn.net/?f=%5CLeftrightarrow%20x%20%3D%20%5Cfrac%7B-3%5Cpm%5Csqrt%7B49%7D%20%7D%7B2.2%7D)
![\Leftrightarrow x = \frac{-3\pm7}{4}](https://tex.z-dn.net/?f=%5CLeftrightarrow%20x%20%3D%20%5Cfrac%7B-3%5Cpm7%7D%7B4%7D)
Either x =1 or, ![x = -\frac{5}{2}](https://tex.z-dn.net/?f=x%20%3D%20-%5Cfrac%7B5%7D%7B2%7D)
Answer:
No, his inference is not valid
Step-by-step explanation:
the data shown represents the statistic of 100 people's preferred ways to view movies in total
out of that 30/100 people prefer to watch in theatre.
trent inferences that out of 400 people 300 would prefer to watch in theatre another way to write this is 300/400
if we multiply the data we're given so that the denominators match Trent's inference. The data tells us that 120/400 would prefer to watch in theatre, so his inference is not valid.
here to find the factors firstly we need to find the zeros of the function , zeros are those points at which the graph crosses or touches the x axis
Now we can see the zeros are x=4 and x=6
And we can write the factors as (x-4) and (x-6)
So the factorization would be
(x-4)(x-6)
Answer:
The equation –3y = 15 – 4x rewritten in slope-intercept form is
✔ y = (4/3)x – 5
.
The y-intercept is
✔ –5
and the slope of the line is
✔ 4/3
.
Line
✔ B
is the graph of the line –3y = 15 – 4x.
