First question, answer is A, the starting point in the graph shows it’s (0,150) while the slope is 30, look at the labeled axis.

second question, i have to do work for it, i can answer it later. remind me. but in order to find the slope, the formula is delta y over delta x. then to find the y intercept, do what’s called “collect the evidence”. this is when you fill out all needed info, it will look like this- y= x= m= b= ??

idk ab the third question, they would all make the function fine?? idk i’m confused, it doesn’t make sense

fourth question, the answer would be B

Select the two values of x that are roots of this equation 2x^2+1=5x​
Zanzabum

Answer:

2.28 and 0.22

Step-by-step explanation:

2x²+1=5x

2x²-5x+1=0

this cannot be properly factorized

so let's use the almighty formula,

- b  +  -  \sqrt{( {b}^{2} }   - 4ac) \:  \times  \frac{1}{2a}

where a=2, b=-5, c= 1

=-(-5)±√{(-5)²-4x2x1} x 1/(2 x 2)

=5±√25-8 x1/4

=5±√17 x ¼

=(5±4.12)/4

=2.28. or. 0.22

roots=2.28 and 0.22
