Answer:
3/2
Step-by-step explanation:
Answer:
y = 3/2x - 2
Step-by-step:
Points: (2,1),(0,-2)
m= y/x —> -3/-2 —> 3/2
y =mx+b
1 =3/2(2)+b
1 = 3+b
1 - 3 =b
-2 = b
y = 3/2x - 2

Answer:
8.6
Step-by-step explanation:
There is an easier way which is finding the slope of the equation but I'm going to stick to distance formula(which is easier for me).
For this, you would have to know the distance formula which is
d=√(x2−x1)^2+(y2−y1)^2
Which simplifies into [tex]\sqrt{(7)^2 +(5)^2}[/tex] which you get from 6-(-1) and -2-(-7)
Further simplifies into [tex]\sqrt{49+25}[/tex]
=[tex]\sqrt{74}[/tex]
=8.602325
use the distance formula:
√ ( x2 - x1 )² + ( y2 - y1 )²
√ ( 6 - ( - 1 ) )² + ( - 2 - ( - 7 ) )²
√ ( 7 )² + ( 5 )²
√ 49 +25
√ 74
8.602325267
8.6 is the answer

Answer:
Lauren's triangle is an isosceles triangle
Step-by-step explanation:
Given the sides of a triangle as 7mm, 9mm and 7mm.
From the given sees you will see that two of the sides are the same showing that the triangle is an isosceles triangle.
An isosceles triangle is a triangle that as two of its sides equal and since two of the sides are both 7mm, hence Lauren's triangle is an ISOSCELES TRIANGLE

Which sum or difference is modeled by the algebra tiles?
A. (x2 - 2x + 3) - (-x - 4x - 2) = 2x - 1
B. (x - 2x - 3) + (x2 - 4x + 2) = 2x - 1
C. (x2 - 2x-3) - (x + 4x + 2) = 2x - 1
D.(X2-2x-3) + (-x2 +4x+2)=2x-1
The sum or difference modeled by the algebra tiles shown in the image is: [tex](x^2 - 2x - 3) - (x + 4x + 2) = 2x - 1[/tex]. The correct option is C.
What is algebra?Algebra is a branch of mathematics that deals with symbols and the rules for manipulating those symbols.
The tiles on the left side of the equation represent the polynomial x^2 - 2x - 3, which can be factored as (x - 3)(x + 1).
The tiles on the right side of the equation represent the polynomial -x - 4x - 2, which can be simplified as -5x - 2.
Substituting these expressions into the original equation, we get:
(x - 3)(x + 1) - (-5x - 2) = 2x - 1
Expanding the left side and simplifying, we get:
[tex]x^2 - 2x - 3 + 5x + 2 = 2x - 1[/tex]
Simplifying further, we get:
[tex]x^2 + 3x - 2 = 2x - 1\\x^2 + x - 1 = 0[/tex]
This is a quadratic equation that can be factored as (x + 1)(x - 1) = 0, which has roots x = -1 and x = 1.
Therefore, the sum or difference modeled by the algebra tiles is C. [tex](x^2 - 2x - 3) - (x + 4x + 2) = 2x - 1.[/tex]

Answer:
106°
Step-by-step explanation:
The requried measure of the angle m∠ UTS is given as 106°.
What is an angle bisector?An angle bisector is the line segment that bisects the angle into two equal halves.

For rhombus,
Diagonal of the rhombus, it bisects the angle of the rhombus.
So,
10x - 23 = 3x + 19
x = 37
Now,
∠RUT + ∠UTS = 180
[37 + 37] + ∠UTS = 180
∠UTS = 180 - 74
∠UTS = 106°
Thus, the requried measure of the angle m∠UTS is given as 106°.

If the arc measure is 90 degrees and the diameter of the circle is 10, what is the arc length?
Answer:
2.5π
Step-by-step explanation:
First, let's find the circumference of the circle. The circumference is equal to dπ, or the diameter times π.
Knowing the diameter is 10, we can easily find that the circumference is 10π.
10π is the entire circumference, but we only need 90° of the circle. If the whole circle is 360°, then that means the portion we need is 90°/360°, which is 1/4.
1/4 times 10π is equal to 2.5π.
2.5π is the arc length.

. Neve is examining a tree limb. She notices that the smaller branches spiral away from the larger limb. The limb has 1 branch, then another single branch. After that, the branches spiral in the pattern {2, 3, 5, 8, …}. Can you model the tree growth with the Fibonacci sequence? Explain.
Answer:
[tex]a_1=2\\a_n=a_{n-1}+(n-1)\,,n>1[/tex]
Step-by-step explanation:
Given: The smaller branches spiral in the pattern [tex]\{2,3,5,8,...\}[/tex] from a larger limb.
To model: the tree growth with the Fibonacci sequence
Solution:
Take [tex]a_1=2[/tex]
Let [tex]a_n[/tex] denotes the [tex]n^{th}[/tex] term.
[tex]a_2=3=2+1=2+(2-1)=a_1+(2-1)\\a_3=5=3+2=3+(3-1)=a_2+(3-1)\\a_4=8=5+3=5+(4-1)=a_3+(4-1)[/tex]
So,
[tex]a_1=2\\a_n=a_{n-1}+(n-1)\,,n>1[/tex]
Answer:
Yes.
Step-by-step explanation:
The pattern in which the branches are growing off the limb is {1, 1, 2, 3, 5, 8, …}, meaning you can use the model with tree growth.
Dan bought a new computer for $900. Each year, the value of the computer decreased by 25% of the previous year's value. At this rate, what can Dan expect the approximate value of the computer to be after 8 years?
Answer:
$90
Step-by-step explanation:
Given data
Price= $900
Rate= 25%
Time= 8 years
Let us apply the compounding formula
A= P(1-r)^t >>>>note that the negative sign is because of the depreciation
substitute
A= 900(1-0.25)^8
A= 900(0.75)^8
A= 900*0.100
A= $90
Hence the value of the car after 8 years will be $90

Answer:
A factor is a circumstance or action that will/would influence an outcome.
A variable is something that is liable to change or something that isn't temporary.
A product is a result of an action or a process.
Coefficient means a quantity is being multiplied by the variable, for instance:
4 (the coefficient) X (the variable) - (the operator) 7 (the constant) = 5 (the constant)
What that looks like is: 4x-7=5.

Answer:
it must be y=-5x+21
Step-by-step explanation:
lets type the equation in front of us and make it simple so we can deal with it
y-1=-5(x-4)
first thing you need to do is to remove those brackets by multiplying whats in the bracket by -5 like this
y-1=-5x+20 -5*x=-5,, -5*-4=20 (note: when you multiply negative with
negative result is positive)
then add each side by 1 so it will be
y=-5x+21

Answer:
S₁₂ = 531440
Step-by-step explanation:
There is a common ratio between consecutive terms, that is
r = 6 ÷ 2 = 18 ÷ 6 = 3
This indicates the sequence is geometric with sum to n terms
[tex]S_{n}[/tex] = [tex]\frac{a(r^n-1)}{r-1}[/tex] ( r ≠ 1 )
where a is the first term and r the common ratio
Here a = 2 and r = 3 , then
S₁₂ = [tex]\frac{2(3^{12}-1) }{3-1}[/tex]
= [tex]\frac{2(531441-1)}{2}[/tex]
= 531441 - 1
= 531440

Grace earns $7 for each car she washes. She always saves $29 of her weekly earnings. This week, she wants to have at least $58 in spending money. How many cars must she wash? Enter and solve an inequality to represent this situation.
SOMEONE PLEASE HELP!!!!!!!!
In order to figure out how many cars she must wash, first you should figure out how much money total you need. This week, she needs $25 for her weekly earnings + $65 for spending money = $90. Then you divide the total amount of money, $90, by 7. The answer is 12.8, but because you can't wash 12.8 cars, the answer is 13.

Can of soup has a radius of 3.4 centimeters. Can is 10.2 centimeters tall, what is the approximate area of the label that wrap around the can?
Answer:
218 cm²
Step-by-step explanation:
Can of soup has a radius of 3.4 centimeters. Can is 10.2 centimeters tall, what is the approximate area of the label that wraps around the can?
The formula to solve the above question is given as:
The curved or the lateral surface area of the cylinder = 2πrh
Where:
r = 3.4 cm
h = 10.2 cm
The curved or the lateral surface area of the cylinder = 2 × π × 3.4 cm × 10.2 cm
= 217.9 cm²
Therefore, the approximate area of the label that wraps around the can is
218 cm².
