Step-by-step explanation:

The coordinate plane is a two-dimension surface formed by two number lines. One number line is horizontal and is called the x-axis. The other number line is vertical number line and is called the y-axis. The two axes meet at a point called the origin. We can use the coordinate plane to graph points, lines

Discriminate

Answers

Answer:

D = 41

Step-by-step explanation:

y = ax² + bx + c

The discriminant D = b² - 4ac tells the types of roots the equation has.

If D < 0 , then quadratic equation has no real roots, has two imaginary roots.

If D = 0 , then quadratic equation has one real root.

If D > 0 , then quadratic equation has two distinct real roots.

~~~~~~~~~~~~

x² + 5x - 4

a = 1, b = 5, c = - 4

D = 5² - 4(1)(- 4) = 25 + 16 = 41

Step-by-step explanation:

This is a special triangle 45, 45, 90 therefore you just multiply the sides by sqrt(2) to find the hypotenuse so it will be 4 sqrt(2)

Another way to do it is by Pythagorean triangle which will still lead to 4 sqrt(2)

Little billy wants to buy a pineapple upside down came. The cakes are 2 days old so they are 70% off! The original price is $20. What is the sale price

Answers

Answer:

$6

Step-by-step explanation:

Original price of the pineapple = $20

Percentage off = 70%

Amount discounted = 70% of $20

Amount discounted  = 0.7 * 20

Amount discounted  = $14

Sale price = Original price - Discount

Sale price = $20 - $14

Sale price = $6

Hence the sale price was $6

Clara found the product of 3 – 6y2 and y2 + 2. Her work is shown below.

(3 – 6y2)(y2 + 2) = 3(y2) + (–6y2)(2)

= 3y2 – 12y2

= –9y2

Is the student’s work correct?

Answers

Answer: No the students work is not correct. Because you are using distribution. Which means that 3 has to multiply the y2 and 2 not just the y2! And after you distribute it you need to simplify!

Step-by-step explanation:

Answer:

(3 – 6y²)(y² + 2) = - 6y⁴ - 9y² + 6

Step-by-step explanation:

Given the expression

3-6y² and y²+2

We have to find the product of 3-6y² and y²+2

Clara's Solution:

(3 – 6y²)(y² + 2) = 3(y²) + (–6y²)(2)

                          = 3y² – 12y²

                          = -9y²

NO!

The student's work is INCORRECT!

Clara did not imply the correct distribution of multiplying the terms in the first step.

Here is the correct solution:

(3 – 6y²)(y² + 2) = 3(y²) + (–6y²)(2) + (3)(2) + (–6y²)(y²)

                          = 3y² – 12y² + 6 - 6y⁴

                           = - 6y⁴ - 9y² + 6

Therefore,

(3 – 6y²)(y² + 2) = - 6y⁴ - 9y² + 6

Answer:

Step-by-step explanation:

The upper vertex would be ...

  3/2(3, 3) = (4.5, 4.5)

and the right vertex would be ...

  3/2(4, 0) = (6, 0).

The base of the larger triangle would be 6, and its height would be 4.5. Then the area is ...

  A = (1/2)bh

  A = (1/2)(6)(4.5) = 13.5 . . . area of dilated triangle

Write an equation of the line in slope intercept form

Answers

Answer: y = x + 2 OR f(x) = x + 2

Step-by-step explanation:

Calculating slope:

Remember rise over run; when going from one point to another point, in this case from (-3, -1) to (0,2), locate the distance moved in the x and y directions. This scenario moves 3 up and 3 right, meaning a positive slope of one. However, if the line was directed left, your slope would be negative.

Finding y-intercept:

Where does the line intersect the y-axis and have a x-value of 0? This is your y-intercept --> (0,2).

Write Equation:

y = mx +b

y = 1x + 2

y = x + 2 (your final answer)

Find the missing terms 14.5_,_,18.4

Answers

The first term is a which is equal to 14.5

The 4th term is a + 3d = 18.4

We know what a is so we can substitute it into the above equation...

14.5 + 3d = 18.4

3d = 3.9

d = 1.3

So the common difference is 1.3... now you just have to add that to the first term so...

14.5 + 1.3 = 15.8 (2nd term)

15.8 + 1.3 = 17.1 (3rd term)

A man sold a fan for Rs. 400. Find the cost price if he incurred a loss of 15%.

Answers

Answer:

Cost price of the fan is [tex]\text {Rs. 470.59}[/tex].

Step-by-step explanation:

Given: A man sold a fan for  [tex]\text{Rs.}\:400[/tex]. He incurred a loss of [tex]15\%[/tex].

To find: The cost price of the fan

Solution:

We have,

Selling price, S.P.,  of the fan [tex]= \text{Rs.} 400[/tex]

Loss [tex]=15\%[/tex]

We know that [tex]\text {Loss\%}=\frac{\text{C.P.-S.P.}}{\text{C.P.}}\times100\%[/tex]

Now let the C.P. of the fan be [tex]\text{Rs.} \:x[/tex]

So, [tex]15=(\frac{x-400}{x})\times 100[/tex]

[tex]\implies 15x=100x-40000[/tex]

[tex]\implies 100x-15x=40000[/tex]

[tex]\implies 85x=40000[/tex]

[tex]\implies x=\frac{40000}{85}[/tex]

[tex]\implies x= 470.59[/tex]

Hence, the cost price of the fan is [tex]\text {Rs. 470.59}[/tex].
