B.–5 and –1
C.–1 and 4
D.0 and 4

Answers

C -1 and 4 i just did the test on this

Answer

C.–1 and 4


Explanation

Solving the equations  y = –x² + 4x and y = x – 4

–x² + 4x = x – 4

x² - 4x + x = 4

x² - 3x = 4

x² - 3x + (3/2)² = 4 +  (3/2)²

(x - 3/2)² = 4 +  9/4

              = 6.25

x - 3/2 = √6.25                      or  x - 3/2 = -√6.25

x = 2.5 + 1.5                                        x = -2.5 + 1.5

 = 4                                                        = -1


What is the slope of a line that is perpendicular to the line y = 8x + 5?

Answers

perpendicular lines, slope is opposite and reciprocal
y = 8x + 5 has slope = 8
so perpendicular line slope = -1/8

answer
-1/8

Answer: [tex]\dfrac{1}{8}[/tex]

Step-by-step explanation:

The given equation of a line : [tex]y = 8x + 5[/tex]

We know that general Slope-intercept form of equation is given by :-

[tex]y=mx+c[/tex], where m is the slope of the line.

When we compare the given equation the general slope intercept form of equation , we get

Slope of line = 8

We know that the product of slopes of two perpendicular line is -1.

Let m be the slope of  line that is perpendicular to the line [tex]y = 8x + 5[/tex], then we have

[tex]-8\times m=-1\\\\\Rightarrow\ m=\dfrac{1}{8}[/tex]

What do you do if you're looking for least common multiple and all your numbers are prime?

Answers


It’s important to remember the distinction between “greatest common factor” and “least common multiple.” A factor of a particular number is a bit like a multiplicative LEGO piece that makes it up; they’re the numbers that other natural numbers can be broken down into by division. A multiple is the opposite; a number and the number that it’s multiplied by (say, 8 x 5) *become factors* of a new number (40, in this case).

When we talk about finding the “least common multiple” of a set of numbers, what we’re asking is this: if you list out multiples of each number, what’s the *first* number in those lists they all have in common? For instance, if we wanted to find the least common multiple between 3 and 5, we could list out their multiples:

3, 6, 9, 12, 15, 18, 21
5, 10, 15, 20, 25, 30

15 is the first multiple that appears in both lists, so the least common multiple of 3 and 5 is 15.

1.  Given: DC || AB and AD|| BC

2.  If two lines are parallel then a tranversal line makes eight angles.

∠2=∠3 and ∠1=∠4   ( Alternate interior angle )

3 .  If one side is common in two figure then reflexive property use.

CA = CA             (Reflexive )

If we take two triangles ΔDAC and ΔCAB are congruent by above property.

The length of a side of an equilateral triangle is 12. find the length of the altitude

Answers

Final answer:

To calculate the altitude of an equilateral triangle with side length 12, divide the side by 2 and multiply by [tex]\(\sqrt{3}\)[/tex] giving an altitude of approximately 10.3923 units.

Explanation:

To find the length of the altitude of an equilateral triangle with a side length of 12, you can use the Pythagorean theorem. The altitude of the equilateral triangle creates two 30-60-90 right triangles. The altitude is the longer leg in this case, and the side of the triangle is the hypotenuse. In a 30-60-90 triangle, the longer leg (altitude) is [tex]\(\sqrt{3}\)[/tex]times the shorter leg (half of the side of the triangle).

First, divide the side of 12 into two to get the shorter leg of the right triangle, which is 6. Then, multiply 6 by \(\sqrt{3}\) to find the length of the altitude. This results in:

[tex]\(6 \times \sqrt{3} = 6\sqrt{3} \approx 10.3923\)[/tex]

Therefore, the altitude of the equilateral triangle is approximately 10.3923 units long.

divide this polynomial:
(x^2-6x-20) divided by (x+2)
* if someone would be able to tell me how to divide this it would be very MUCH appreciated

Answers

Hi! 

So I'll show you how to divide the polynomial step-by-step

First you want to write this out like any long division problem. 

After that you need to see what times x is x^2?

x*x is x^2 so you want to write x over -6x, you have to make sure that you write it over the same degree term. 

Now you multiply both x and 2 (which came from the x +2) by x (which was what you wrote in your first part of the quotient) 

Then you subtract what you got from multiplying the x and 2 by x (you should have gotten -8x) 

Now you want to bring down the next term in the dividend. 


So you want to see what times x is -8x? (This should be -8)

Now you write -8 in the quotient. Now your quotient should be x-8.

After that, you want to multiply x+2 by the -8 and subtract again. (you should get -4)

Since you've filled in the last space in your quotient you have a remainder of -4. Remember to write the remainder as a fraction, -4/x+2

What is the measure of ∠SPQ in this rhombus?
m∠SPR = (2x+13)°
m∠QPR = (3x−12)°

Answers

The measure of ∠SPQ in the rhombus PQRS, based on ∠ SPR = (2x+13)°, and ∠ QPR = (3x-12)°, is the sum of the two angles of ∠ SPR and ∠ QPR, which equal the whole or ∠ SPQ, in other words (2x+13)° + (3x-12)°.

Solution:

In a Rhombus The diagonals bisect the angles.

m∠SPR=m∠QPR

Substituting the given values :

2x+13=3x-12

Subtracting 2x both sides:

13=3x-2x-12

13=x-12

Adding 12 both sides:

x=25.

m∠SPR=2x+13=2(25)+13=50+13=63

m∠SPQ=2∠SPR

m∠SPQ=2m∠SPR

m∠SPQ=2x63=126

m∠SPQ= 126 degrees

Kendra is making a large salad for a party. She buys lettuce for $2.25 per pound and tomatoes for $2.65 per pound. She spends at least $8.

Let x represent the number of pounds of lettuce that Kendra buys. Let y represent the number of pounds of tomatoes that Kendra buys.

Which inequality represents this situation?


A. 2.25x+2.65y>8

B. 2.25x+2.65y<8

C. 2.25x+2.65y≤8

D.2.25x+2.65y≥8

Answers

The answer is D.
I hope this helps.

Answer:  The correct option is

(D) [tex]2.25x+2.65y\geq8.[/tex]

Step-by-step explanation:  Given that Kendra is making a large salad for a party. She buys lettuce for $2.25 per pound and tomatoes for $2.65 per pound. She spends at least $8.

x represent the number of pounds of lettuce that Kendra buys and y represent the number of pounds of tomatoes that Kendra buys.

We are to select the inequality that represents the situation.

We have

total amount of money that Kendra spends on lettuce is given by

[tex]a_l=2.5\times x=2.5x[/tex]

and the total amount of money that she spends on tomatoes is

[tex]a_t=2.65\times y=2.65y.[/tex]

Therefore, the inequality can be written as

[tex]a_l+a_t\geq 8\\\\\Rightarrow 2.25x+2.65y\geq8.[/tex]

Thus, option (D) is CORRECT.

What is the new price of s shirt that is on sale for 50% off and has an original price of $50?

Answers

50%=1/2 or 1 half. 50/2=$25

Final answer:

To calculate the new price of the shirt on a 50% sale off its original price of $50, divide the original price by 2, resulting in a new price of $25.

Explanation:

The question asks us to calculate the new price of a shirt that is on sale with a 50% discount from its original price of $50. To find the new price, you simply need to reduce the original price by the percentage of the discount. Since a 50% discount cuts the price in half, you divide the original price by 2.

Calculation:

Original price of the shirt: $50

Discount: 50% of $50 = $50 / 2 = $25

New price after discount: $50 - $25 = $25

Therefore, the new price of the shirt after a 50% discount is $25.
