Answer:
2a + 3b = 0
Step-by-step explanation:
So we are given that a = -3, b = 2, c = 5, and d = -4 and we are asked to evaluate the expression 2a + 3b. To evaluate the expression, we would have to plug in -3 for a, 2 for b, 5 for c, and -4 for d:
2a + 3b = 2(-3) + 3(2) = -6 + 6 = 0
So by evaluating the expression we get 0.

which is the correct value of c for x^2-14x+c=(x-7)^2
Answer:
c = 3.5 - x
Step-by-step explanati
x^2 - 14x + c = (x - 7)^2
x^2 - 14x + c = x^2 - 7^2
x^2 - 14x + c - x^2 = x^2 - 49 - x^2
-14x + c = 49
-14x / -14 + c = 49 / -14
x + c = 3.5
x - x + c = 3.5 - x
c = 3.5 - x

State if the two triangles are congruent. If they are, state how you know.
Answer:
The triangles can be congruent.
Step-by-step explanation:
They are congruent if proven by SSS: 2 sides are clearly stated that they are congruent due to the marks they have.
The last side can be congruent if the diagonals are congruent in length by proving.
They can also be congeuent due to SAS because there is gonna be alternate interior angles due to the transversal.

write a paragraph proof for the following conjecture
Given m∠1 + m∠2 = m∠4
Prove: m∠3 + m∠1 + m∠2 = 180°
m∠1 + m∠2 = m ∠4 , under the exterior angle property of a triangle which says that sum of the interior opposite angles of an exterior angle will be equal to the measure of the exterior angle .
To prove that m∠3 + m ∠1 + m∠2 = 180° , let us use the angle sum property .
= Angle sum property = Sum of the three interior angles in a triangle will be equal to 180° .
= Since ∠1 , ∠2 and ∠3 are the interior angles of this triangle , their sum will be equal to 180° .
Hence proved that m∠1 + m∠2 + m∠3 = 180°
∴ m∠1 + m∠2 + m∠3 = 180° under the angle sum property of a triangle .

What are the slope and y-intercept of the graph of y=−13x+1
Answer:
Hi there!
Your answer is:
slope: -13
y-int: 1
Step-by-step explanation:
The slope is the x coefficient, rise/run
In this case, its -13/1. Which means it has a slope of -13.
The y int is the constant term.
In this case, its 1. Which means it crosses the y axis at 1

A boat cost $16,500 and decreases in value by 13% per year how much will the boat be worth after eight years?
Answer:
$5,415.49
Step-by-step explanation:
Cost of the boat = $16,500
Decrease in value per year = 13%
Worth of the boat in 8 years = ?
Remaining value = 100% - 13%
= 87%
Worth of the boat in 8 years = cost of the boat × remaining value^8
= $16,500 × 87%^8
= $16,500 × 87/100^8
= $16,500 × 0.87^8
= $16,500 × 0.3282116715437121
= $5,415.49
The worth of the boat after 8 years = $5,415.49

Which statements about the values of 4.099 and 40.99 are true? Select all that apply. 4.099 is 110 of 40.99. 4.099 is 1100 of 40.99. 40.99 is 10 times more than 4.099. 40.99 is 100 times more than 4.099. 4.099 is 10 times more than 40.99.
Answer:
40.99 is 10 times more than 4.099
Step-by-step explanation:
Given the values :
4.099 and 40.99
4.099 is 110 of 40.99 : 110 * 40.99 = 4508.9 (false)
4.099 is 1100 of 40.99 : 1100 * 40.99 = 45089 (false)
40.99 is 10 times more than 4.099 : (10 * 4.099) = 40.99 (true)
40.99 is 100 times more than 4.099 : (100 * 4.099) = 409.9 ( false)
4.099 is 10 times more than 40.99 : (10 * 40.99) = 409.9 (false)

You rode 180 miles at 60 miles per hour. Let t be the time it took. Can t be 4 hours?
Answer:
t = 3 hours, therefore it cannot be 4 hours
Step-by-step explanation:
Divide the miles traveled by the rate you traveled. This will find the time it took to travel.
180/60 = 3
You drove 3 hours to travel 180 miles, therefore t cannot equal 4.

The Number Line
A number line is defined as a graphic representation of numbers such as fractions, integers, and whole numbers laid out evenly on a straight horizontal line.
The number line can be used for comparing and ordering numbers and also performing simple operations such as addition and subtraction.
There are four numbers located on a number line. Let's analyze each one:
A: -27/3. This division is a whole number =.9 and is correctly placed.
B: -13/2 = -6.5. Note this value was incorrectly placed at -4.5.
C: 9/2= 4.5. The number is correctly placed

10. Calculate the speed of waves in a puddle that are .15 apart and made by tapping the water
surface twice each second.
Since the waves are 0.15 apart and made by tapping the water surface twice each second the speed of waves in the puddle is 0.6 m/s
To answer the question, we need to know what a wave is
What is a wave?A wave is a disturbance in space which carries energy from one point to another
What is the speed of a wave?The speed of a wave v = fλ where
f = frequency and λ = wavelengthWavelength of waveSince the puddles are 0.15 m are and we know that this is the distance from crest to crest.
Also, the distance from crest to crest is λ/2
So, λ/2 = 0.15
λ = 2 × 0.15 m
= 0.3 m
Frequency of wave
Also, since the tapping by the water surface is done twice each second, the frequency, f = 2 times/s = 2 Hz
Speed of waves in puddleSubstituting the values of the variables into the equation, for speed, we have
v = fλ
v = 2 Hz × 0.3 m
v = 0.6 m/s
So, the speed of waves in the puddle is 0.6 m/s

to find the slope of the two points
Answer:
Slope is :-
[tex] \boxed{\bf \; m \; = - \cfrac{7}{5}} [/tex]
Step-by-step explanation:
Given two points :-
[tex] \sf \implies(-5,3) , (0,−4)[/tex]
To Find :-
The slope of Two points that is given.
Solution :-
[tex]\sf \implies(-5,3) , (0,−4)[/tex]
As we know that the formula of Slope is :-
[tex]\sf \implies \boxed{\sf Slope = \cfrac {y_2 - y_1}{x_2 - x_1}}[/tex]
Now, Put the values of x and y :-
Where,
[tex]{ \sf \: {y_2} = - 4}[/tex]
[tex] \sf \: x_2 = 0[/tex]
[tex] \sf \: y_1 = 3[/tex]
[tex] \sf \: x_1 = - 5[/tex]
Put the values on their respective place :-
[tex]\sf \implies \: Slope = \cfrac{ - 4 - 3}{0 - ( - 5)} [/tex]
Simplify this Fraction :-
Add -4 and -3 which is on the numerator as we know that "-" and "-" equals to "+":-
[tex]\sf \implies \: Slope = \cfrac{ - 7}{0 - ( - 5)} [/tex]
Now Add 0-(-5) on the denominator as we know that "-" and "-" equals to "+":-
[tex]\sf \implies \: Slope = \: \cfrac{ - 7}{ 5} [/tex]
Which can be rewritten as,
[tex]\sf \implies \: m = \: - \cfrac{7}{5} [/tex]
This fraction can't be cancelled. Hence, the slope of the two points is:-
[tex]\sf \implies \boxed{\sf m = \: - \cfrac{7}{5}} [/tex]
Note :- Slope can also be denoted as [tex] m [/tex].
