lisov135 [29]

Sanjay and Felipe would take a time of 3.4 hours to do the puzzle if they were working together.

<h3>What is the time?</h3>

Time can be described in mathematics as an ongoing and continuous series of events that take place one after another, from the past through the present and into the future.

The amount of time that something exists or continues to happen as measured or measurable.

The duration of events or the gaps between them can be measured, compared, or even ordered using time.

Time taken by Sanjay= 6 hours

Time taken by Felipe= 8 hours

Time taken by both if they work together,

=\frac{1}{1/6+1/8}

=\frac{1}{\frac{4+3}{24} }

=24/7

=3.4 hours

Use the quadratic formula to find both solutions to the quadratic equation given below 4x^2+3x-1=0
Aneli [31]
    4x²  +  3x    -  1 = 0
a=4      b=3   c=-1

Quadratic formula:
x =\frac{-b +/-  \sqrt{b^{2} -4ac} }{2a} =  \frac{-3 +/-  \sqrt{3^{2} - 4(4)(-1)}}{2(4)}
= \frac{-3 +/-  \sqrt{9 + 16}}{8} =  \frac{-3 +/-  \sqrt{25}}{8} =  \frac{-3 +/-  5}{8}
= \frac{-3 + 5}{8} , \frac{-3 - 5}{8}
= \frac{2}{8}, \frac{-8}{8}
= \frac{1}{4}, -1

Once again, I can’t figure it out. Can you help me again
malfutka [58]

Cross multiply: 20 * b = 45 * 34

Simplifying: 20 * b = 45 * 34

Multiply 45 * 34: 20b = 1530

Solving: 20b = 1530

Solving for variable 'b'.

Move all terms containing b to the left, all other terms to the right.

Divide each side by '20': b = 76.5

Simplifying: b = 76.5

Can you pleasee explain how to find a y- intersept??
AveGali [126]

a y-intercept is any point that has an x-value of 0. for example, the ordered pairs (0,6) and (0,-4) would both be considered y-intercepts since any point with an x-value of 0 overlaps with the y-axis.
