What’s the gradient and y intercept for c and e and could u explain pls thx

Answers

Step-by-step explanation:

if you are given an equation of a form y=kx+b, k is gradient and b is y-intercept

in c you can write this equation as y=(2x/3)-2,so gradient = 2/3 and y-intercept =-2

in e:6y=2x+3

y=x/3+1/2,gradient = 1/3, y-intercept=1/2

The gradient or Slope in a linear equation is simply the value "a" in this equation : y = ax + b

And the y-intercept is simply the value b.

so for example, what is the slope of y = 5x + 3 ? What is the y-intercept ? Well the gradient (or slope) is 5, and the y-intercept is 3.

So, for a.

y = -1/2x + 8

it's pretty simple : gradient = -1/2

y intercept = 8

Now for c.

[tex]y=\frac{2x-6}{3}[/tex]

[tex]y=\frac{2}{3}x-\frac{6}{3}[/tex]

[tex]y=\frac{2}{3}x-2[/tex]

So the gradient is 2/3 and the y intercept is -2 (and not +2, be careful there is a negative sign :) )

-2x + 6y - 3 = 0

6y = 2x + 3

y = (2/6)*x + (3/6)

y = (1/3)*x + (1/2)

so the gradient is 1/3

and the y-intercept is 1/2

Good luck, your the best :)

I WILL GIVE BRIANLISTSActivity Thinking About Circles Around You Do this activity together to investigate circles in the real world. Have you ever wondered why runners start at different spots on a track instead of lining up together? This is called a staggered start. Sincetrac Since tracks have semicircles (or half circles) on the ends, if all the runners lined up together, runners in outer lanes would need to run farther than runners in inner lanes. Why? Because the circumference of the outer lane is greater than the circumference of the inner lane. Staggering starting positions ensures that all runners run the same distance! ? Where do you see circles and semicircles in the world around you? Why could finding the area or circumference be helpful?

Is there a value of x that makes each of the following equalities true? If there is, find it.
a. √x-3=0
b. √x=-10
c. √x+1=0
d. √x=0.1

Answers

Step-by-step explanation:

a. √x - 3 = 0 ⇒ √x = 3 ⇒ x = 3² ⇒ x = 9 b. √x = -10,

no solution as √x is a positive value

c. √x+1=0 ⇒ √x = - 1,

no solution as √x is a positive value

d. √x = 0.1 ⇒ x = 0.1² ⇒ x = 0.01

√x-3=0x-3=0x=3

If square root is over x only x=3²=9

No solutions as -10 is <0

√x+1=0x+1=0x=-1

If root is over x only then no solutions

√x=0.1

x=0.01

How to find where inflection points are.

Answers

here’s the answer !! have a good day

An inflection point is a point on the graph of a function at which the concavity changes. Points of inflection can occur where the second derivative is zero. In other words, solve f '' = 0 to find the potential inflection points. Even if f ''(c) = 0, you can't conclude that there is an inflection at x = c.

22 meters per second in kilometers per hour.

Answers

Answer:

79.2 kilometres per hour

Step-by-step explanation:

1 km = 1000 m

1 hr = 3600 sec. To convert km/hr into m/sec,

We multiply the speed which in this case is 22m/s

by 3.6 giving 79.2 kmh. Therefore 22m/s into kilometer is 79.2 kmh.
