Answer:
#1) 4 x 3 - 1 is less than or equal to 11 (it's equal). 4 x 3 - 1 < 11 is not true because 11 is not less than 11.
Step-by-step explanation:
#2) 8x + 1 = 57 --- subtract 1 from both sides
8x = 57 - 1
8x = 56 -- divide both sides by 8
x = 7.....any other value for x will not work
Answer:
y = 2x - 3
Step-by-step explanation:
the formula for finding equation of a line is m = (y2 - y1 )/(x2 - x1). that is (7-3)/(5-3) which gives you 4/2 = 2.
you then chose one of the point and fill in the equation y - y1 = m (x -x1)
So let's chose (3,3) and fill in.
y - 3 = 2 (x - 3)
y - 3 = 2x - 6
y - 2x = -6 + 3
y - 2x = -3
Hence, the equation of the line is y = 2x - 3

<h3>Answer: 2 different real number solutions </h3>
Both solutions are irrational.
===============================================
Explanation:
The given function f(x) = 5x^2+2x-12 is in the form f(x) = ax^2+bx+c
We see that
a = 5, b = 2, c = -12
Plug those values into the discriminant formula below
D = b^2 - 4ac
D = (2)^2 - 4(5)(-12)
D = 4 - 4(5)(-12)
D = 4 + 240
D = 244
Because D > 0, this means we have two different real solutions for f(x) = 0
The value of D is not a perfect square, so those two solutions or roots are irrational.
