How do you determine the intercepts from an equation or graph

2 answers:

5 0

OK so it's quite easy In a graph it would be the point that touches the y axis. The point that intersects the y axis.

In an equation it would just be the never without the variable

for example

y = 5x+10

The 10 is the y intercept because it doesn't have any other variable next to it

When you want the x intercepts (x,0):. Set y=0 then solve for x

Answer:

See attachment

Step-by-step explanation:

To see clearly the graph that represents

$f(x) = {x}^{2} + 3x + 2$

we rewrite in vertex form to get;

$f(x) = (x + \frac{3}{2})^{2} - \frac{1}{4}$

This is a vertical parabola with vertex at (-1.5,-0.25) and opens upwards.

The required graph is shown in the attachment.

Answer:

well without rounding anything, I got 511.9999999992 people

Step-by-step explanation:

so the ratio I used was 36 people for every 225 people( 225 because in total he asked 225 people) then I divided 3,200 into 225 to see how many times It would fit, the answer was 14.2222222222 then I multiplied that by 36 and my answer was 511.9999999992 people. I hope this helps, I tried to be as accurate as possible.

15% of £70= £10.5

Expenditure =£24+£10.5=£34.5

Net amount raised =gross amount - Expenditure

=£70-£34.5=£35.5

Multiply the following and write your answer In scientific notation.. 3.62 × 10^-5 · 9,400.

svet-max [94.6K]

Answer:

3.4028 x 10^-1

Step-by-step explanation:

First you make the 9400 into scientific notation:

9.4x10^3

Then you combine like terms

(3.62x9.4)(10^-5x10^3)

Finally you simplify

34.028x10^-2

3.4028x10^-1
