Answer:
Remember that the roots are the values of the variable when the expression equals 0.
a: 4 + 3 = 7 and 4*3 = 12 so we have (x + 3)(x + 4) with roots -3, -4
b: -4 + -2 = -6 and -4*-2=8 so we have (t-2)(t-4) with roots 2, 4
c: 2*-4 + 6 = -2 and -4*6=24 so we have (2n+6)(n-4) with roots -3, 4
d: -7+-4 = -11 and -7*-4=28 so we have (y-4)(y-7) with roots 4, 7

A sales person saw the car for 18,250 and their commission is 912 and $.50 what percentage of the sales price is their commission
Answer:
the percentage of the sales price that is their commission is 5 %.
Step-by-step explanation:
Given;
price of the car, P = $18,250
commission, = $912.5
Let the percentage of the sales price that is their commission = y%
The percentage of the sales price that is their commission is calculated as;
[tex]\frac{y}{100} \times 18,250 = 912.5\\\\18,250y = 91250\\\\y = \frac{91250}{18250} \\\\y = 5 \ \%[/tex]
Therefore, the percentage of the sales price that is their commission is 5 %.
There are 42 pets at a local pet shop. Twenty-eight of the pets are fish, and the rest are birds. What is the ratio of fish to birds in the pet shop?
3 to 1
2 to 1
3 to 2
I don't know.
Answer:
Its 2 to 1. I just took the quizz!!!
Step-by-step explanation:
The ratio of fish to birds in the local pet shop is 2:1.
What are equivalent ratios?"Equivalent ratios are those that can be simplified or reduced to the same value. In other words, two ratios are considered equivalent if one can be expressed as a multiple of the other".
For the given situation,
Total number of pets in local pet shop = 42
Number of fish = 28, Then
Number of birds = [tex]42-28[/tex]
⇒ [tex]14[/tex]
Thus ratio of pets to fish = [tex]28:14[/tex]
Simplify the ratio to the smallest fraction
Dividing 14 on both sides,
⇒ [tex]2:1[/tex]
Hence we can conclude that the ratio of fish to birds in the local pet shop is 2:1.

The area of a typical eardrum is about 5.00 10-5 m2. (a) Calculate the average sound power incident on an eardrum at the threshold of pain, which corresponds to an intensity of 1.00 W/m2. 5e-5 Correct: Your answer is correct. W (b) How much energy is transferred to the eardrum exposed to this sound for 4.10 min
Answer:
5 * 10^-5 W
1.23 * 10^-2 J
Step-by-step explanation:
Given that :
Area = 5 * 10^-5 m²
Threshold of Pain = Intensity = 1.00 W/m2
Using the relation:
Intensity = power / Area
Hence,
Power = Intensity * Area
Power = 1 W/m² * 5 * 10^-5 m²
Power = 5 * 10^-5 W
Energy transferred to eardrum. Exposed for 4.10 minutes :
Using the relation :
Energy = Power * time
Energy = 5 * 10^-5 * (4.10 * 60 seconds)
Energy = 5 * 10^-5 W * 246 s
Energy = 0.0123
= 1.23 * 10^-2 J

What is an equation of the line that passes through the points (-6, 2) and
(-4, -1)? Put your answer in fully reduced form.
Answer (assuming the equation can be written in point-slope form):
[tex]y-2 = -\frac{3}{2}(x+6)[/tex]
Step-by-step explanation:
When knowing a point the line crosses through and its slope, you can write an equation in point-slope form, or [tex]y-y_1= m (x-x_1)[/tex].
1) First, find the slope of the line. Use the slope formula [tex]\frac{y_2-y_1}{x_2-x_1}[/tex] and the x and y values of the two points given, then solve like so:
[tex]\frac{(-1)-(2)}{(-4)-(-6)}\\= \frac{-1-2}{-4+6}\\= \frac{-3}{2}[/tex]
Thus, the slope is [tex]-\frac{3}{2}[/tex].
2) Now, use point-slope form, [tex]y-y_1= m (x-x_1)[/tex]. Substitute the [tex]m[/tex], [tex]x_1[/tex], and [tex]y_1[/tex] for real values.
The [tex]m[/tex] represents the slope, so substitute [tex]-\frac{3}{2}[/tex] in its place. The [tex]x_1[/tex] and [tex]y_1[/tex] represent the x and y values of one point the line crosses through. Any of the two points will work, and I chose (-6,2) for this answer. So, substitute -6 for
[tex]y-(2)= -\frac{3}{2}(x-(-6)\\y-2 = -\frac{3}{2}(x+6)[/tex]

Find the area of the polygon pls
Given:
The figure of a polygon.
To find:
The area of the polygon.
Solution:
Area of a triangle is
[tex]Area=\dfrac{1}{2}\times Base\times Height[/tex]
Area of trapezoid is
[tex]Area=\dfrac{1}{2}(a+b)h[/tex]
Where, a, b are bases and h is the height.
The area of the triangle with base 6 cm and height 8 cm is
[tex]A_1=\dfrac{1}{2}\times 6\times 8[/tex]
[tex]A_1=24[/tex]
Height of the trapezoid is [tex]13-8=5\ \text{cm}[/tex] and the bases are 6 cm, 12 cm. So, the area of the trapezoid is
[tex]A_2=\dfrac{1}{2}(6+12)(5)[/tex]
[tex]A_2=\dfrac{1}{2}(18)(5)[/tex]
[tex]A_2=(9)(5)[/tex]
[tex]A_2=45[/tex]
Now, the total area of the polygon is
[tex]A=A_1+A_2[/tex]
[tex]A=24+45[/tex]
[tex]A=69[/tex]
Therefore, the area of the polygon is 69 sq. cm.

—————
3
Answer: -260
Step-by-step explanation:
Answer:
-260
Step-by-step explanation:
First, we have to distribute -10 to 32 and -6, since 32 - 6 is in parentheses.
So, the expression becomes -320 + 60, because -10 × 32 = -320 and -10 × -6 = 60.
So, -320 + 60 = -260
What is the solution of the system? Use elimination.
3 (-5x-2y=6)
3x+6y=6
Answer:
x = -2 and y = 2
Step-by-step explanation:
The given equations are :
-5x-2y=6 ...(1)
3x+6y=6 ...(2)
Multiply equation (1) by 3. SO,
-15x-6y=18 ...(3)
Adding equation (2) and (3).
3x+6y-15x-6y = 6+18
-12x = 24
x = -2
Put the value of x in equation (1).
-5(-2)-2y=6
10-2y=6
4=2y
y = 2
So, the value of x is -2 and y is 2.
what's the gcf for x^3 y^2 and xy^5
=====================================================
Explanation:
We can rewrite x^3y^2 into x*x^2*y^2
We can rewrite xy^5 into x*y^2*y^3
Note how x*x^2*y^2 and x*y^2*y^3 both have an x in common. So that means x is part of the GCF.
Similarly, x*x^2*y^2 and x*y^2*y^3 have y^2 in common as well.
Overall, both original expressions contain x and y^2 which leads to the overall GCF being xy^2

(9y-6)° 51°
Answer:
5
Step-by-step explanation:
This is a right angle which means it is equal to 90. The angle is separated into two parts as shown - the sum of these two parts is equal to 90.
Calculations:
9y - 6 + 51 = 90
9y + 45 = 90
9y = 45
y = 5

an isosceles right triangle has an area 8 cm square find the length of its hypotenuse
please answer me fast
Answer:
5.9
Step-by-step explanation:
Area of a triangle is 1/2 base times height. the base is the horizontal part of the triangle and the height is the vertical part. Since it a isosceles they are equal. Those two segment are also called the legs (remember that for later). 4x4=16 times 1/2 equal 8 cm squared. So know me must find the hypotenuse. Since we since dealing with a right triangle we are going to use pythagorean theorem which is
[tex] {a}^{2} + {b}^{2} = {c}^{2} [/tex]
where a and b are the LEGS and c is the hypotenuse. the legs are also known as base and height so we use
[tex] {4}^{2} + {4}^{2} = {c}^{2} [/tex]
which simplify to
[tex]16 + 16 = {c}^{2} [/tex]
[tex]32 = {c}^{2} [/tex]
[tex] \sqrt{32} [/tex]
which is about 5.9

It goes up 6 and 1 across 6/1 = 6
Answer: 6
Step-by-step explanation:
The easiest way to find slope is by [rise/run] or literally the y value over the x value. In this way, you need to find two points that are on the intersections of the gridlines, then count the units in between
---------------------------------------------------------------------------
(-8, 4) (-9, -2)
