Describe how you would determine the x-intercepts from the factored form of a quadratic equation

Mathematics
1 answer:
Aloiza [94]3 years ago
4 0

Answer:

Please check explanations

Step-by-step explanation:

Given the factored form, all we have to do is to equate each of the factor to zero, then solve for x

The particular value of x represents the solution that shows the value of the x-intercept

for example

In a case of a quadratic equation where we have

(x-a)(x-b) = 0

Then we can have

(x-a) = 0 or ((x-b) = 0

Then we have x = a or x = b

a and b are the x intercepts in this case

What is the slope of the line through (1, -1) and (5. – 7)?
Vladimir [108]

Answer:

-3/2

Step-by-step explanation:

Given two points, we can find the slope by

m = (y2-y1)/(x2-x1)

    = (-7 - -1)/ (5-1)

    = (-7+1)/(5-1)

    = -6/4

    = -3/2

5.<br>Find the sum of all two - digit natural numbers which are divisible by 3.​
kykrilka [37]

Answer:

1665

Step-by-step explanation:

This is AP, where:

  • First term is: 12= 3*4
  • Last term is: 99= 3*33
  • Common difference is: 3
  • Number of terms is: 33- 3= 30 (because the 4th term is included)
  • S=1/2*30(12+99)= 1665

The sum of all two - digit natural numbers which are divisible by 3 is 1665

Solve for the indicated variable in each scientific formula. c=wtc/1000 for w
Hitman42 [59]
First, multiply both sides by 1000
1000*c = w*t*c

Since c is on both sides, they would cancel each other out
1000 = w*t

Divide both sides by t.
w = 1000*t
