Find the sum of 5x+20 and the opposite.write an equivalent expression in standard form justify each step
Answer:
Therefore, the sum of 5x+20 and the opposite is: 0Thus, the equivalent expression is:[tex]5x+20-\left(5x+20\right)=0[/tex]
Step-by-step explanation:
We know that the opposite is the additive inverse. For example, 8+(−8)=0 where 0 is the identity for addition.Given that we have to compute the sum of 5x+20 and the opposite.
Given
5x+20opposite of 5x+20 = -(5x+20)so
The sum of 5x+20 and the opposite:
5x+20 + -(5x+20)
Distribute the Negative Sign
[tex]=5x+20+-1\left(5x+20\right)[/tex]
[tex]=5x+20+-1\left(5x\right)+\left(-1\right)\left(20\right)[/tex]
[tex]=5x+20+-5x+-20[/tex]
Combine Like Terms
[tex]=5x+20+-5x+-20[/tex]
[tex]=\left(5x+-5x\right)+\left(20+-20\right)[/tex]
[tex]=0+0[/tex]
[tex]=0[/tex]
Therefore, the sum of 5x+20 and the opposite is: 0Thus, the equivalent expression is:[tex]5x+20-\left(5x+20\right)=0[/tex]

Answer:
20 quarts
Step-by-step explanation:
Five gallons is equal to 20 quarts.
I hope it helps.
Answer:
20 quarts
Step-by-step explanation:
in 1 gallon there is 4 quarts so if theres 5 gallons there would be 4 quarts for each, so multiply 5 by 4, becuase you need 4 quarts in every gallon, the product (answer to a multiplication problem) to that is 20. :)

6y=3y-18 What is thee slope intercept and what is the slope
Answer:
y = (1/2)x - 3
The slope is m = 1/2 and the y-intercept is (0, -3).
Step-by-step explanation:
Assuming that you meant 6y = 3x - 18, we solve this equation for y to obtain the slope-intercept formula y = mx + b for this particular case:
y = (3/6)x - (18/6), or
y = (1/2)x - 3
The slope is m = 1/2 and the y-intercept is (0, -3).

Drag and drop formal proof. Prove the Polygon Exterior Angle Sum Theorem for the enclosed triangle, that is ∠1+∠2+∠3=360°
.
Answer:
The sum of all the external angles of a triangle is 360°.
Step-by-step explanation:
Let there are n sides in a polygon.
So, there are n internal angles in the polygon, let ∠i1, ∠i2, ∠i3, ..., ∠in are the measure of n internal angles of the polygon.
The measure of external angle corresponding to ∠i1, ∠1= 180°-∠i1,
The measure of external angle corresponding to ∠i2, ∠2 = 180°-∠i2,
Similarly, the measure of external angle corresponding to ∠in, ∠n = 180°-∠in.
Now, the sum of all the external angles of the polygon,
(∠1+∠2+...+∠n)=(180°-∠i1)+(180°-∠i2)+...+(180°-∠in)
=(180°+180°+...n times)-(∠i1+∠i2+...+∠in)
=n x 180° - (∠i1+∠i2+...+∠in)
As ∠i1+∠i2+...+∠in is the sum of all the internal angles of the polygon.
So, the sum of all the external angles of the polygon =
(n x 180°) - (sum of all the internal angles of the polygon).
In the case of a triangle, n=3 and the sum of all the three internal angles, ∠i1+∠i2+∠i3 = 180°.
Therefore, the sum of all the external angles of a triangle,
∠1+∠2+∠3 =3x180°-(∠i1+∠i2+∠i3)
=540°=180°
=360°.
Hence, the sum of all the external angles of a triangle is 360°.

Which of the following represents the greatest percent of change?
A. Boots that were originally priced at $90 are on sale for $63
B. A baby that weighed 7 pounds at birth now weighs 10 pounds
C. A bracelet that costs $12 to make is sold for $28
D. A savings account increased from $500 to $600 in one year
Answer:
c
Step-by-step explanation:
a. 63(new) - 90(old) = -27 / 90 = 0.4285*100 = 42.9%
b. 10(new) - 7(old) = 3 / 7 = -0.3*100 = -30 = 30%
c. 28(new) - 12(old) = 14 / 12 = 1.166 * 100 = 116.6%
d. 600(new) - 500(old) = 100 / 500 = 0.2 = 20%
The greatest percentage change will be a bracelet that costs $12 to make and is sold for $28 as 133.33% thus option (C) is correct.
What is the percentage?The percentage is defined as a given amount in every hundred. It is a fraction with 100 as the denominator percentage is represented by the one symbol %.
The percentage is also called the indicating hundredths. Thus, 2% is two-hundredth, which means 2%=2/100=0.02.
As per the given,
% change = (change)/original x 100
A): (90 - 63)/90 x 100 = 30%
B): (10 - 7)/10 x 100 = 30%
C); (28 - 12)/12 x 100 = 133.33%
D):(600 - 500)/500 x 100 = 20%
Hence "The greatest percentage change will be a bracelet that costs $12 to make and is sold for $28 as 133.33%".

Answer:
the line is inconsistent:)
Step-by-step explanation:
Graph the line
y = - 4/3x + 3
I need help with the steps.
Start by putting a dot at (0,3). Then you just need to go four down and three right from that dot and put another dot. Just repeat that a couple times to make sure it is straight, and connect the dots with a line. You can also go four up and three left from the (0,3) for the other side of the axis.
Step-by-step explanation:
First look at the y-intercept or b (in this case it is 3)
The y-intercept tells us where the line touches in the graph on the Y-axis
(In this case you move up in the Y-axis 3 times)
Put a dot on 3 (in the y-axis)
Now from 3 on the y-axis go down -4 and right 3 since the slope is -4/3
(Slope = rise/run -4 is rise [but since it the 4 is a -4 you go down] and 3 is run)
every time you finish going down -4 and right 3 place a dot on it and repeat if you think you can draw a line then stop and draw the line and you are finished

Answer:
y = 9
Step-by-step explanation:
∆KLH is congruent to ∆FLH by the Hypotenuse-Leg Congruence Theorem.
Therefore,
m<KHL = m<FHL
Thus:
6y = 4y + 18
6y - 4y = 18 (subtraction property of equality)
2y = 18
y = 18/2 (division property of equality)
y = 9

Step-by-step explanation:
In order to simplify, add like terms
(8x^2-7x+2)+(3x^2-9x-6)
8x^2 + 3x^2 = 11x^2
-7x + -9x = -16x
-6 + 2 = 4
now the equation is 11x^2 - 16x +4
-9h - 15 = 93 Need help. Not that good at solving two step equations. Algebra's tricky. Please solve.
Answer:
h=12
Step-by-step explanation:
first you want to isolate the variable. since you are subtracting 15, you wanna add fifteen to the 93 and cancel it out on the other side of the equation symbol. that equals 108. how since you are doing 9*h you divide on the opposite side of the equation so 108/9=12. the 9 cancels out meaning h=12

Answer:
74
Step-by-step explanation:
did school asignment
The measurement of ∠ B = 74°
What are Supplementary angles?Two Angles are Supplementary when they add up to 180 degrees.
Given that ∠ A and ∠ B are Supplementary and ∠ A = (3x−23),
∠ B = (2x−12)
According to definition of Supplementary,
∠ A + ∠ B = 180°
(3x−23) + (2x−12) = 180°
5x - 35 = 180°
5x = 180° + 35
5x = 215°
x = 43°
Putting x = 43° in ∠ B = (2x−12)
∠ B = (2*43−12)
∠ B = 86 - 12
∠ B = 74°
Hence, The measurement of ∠ B = 74°

The original Volkswagen Beetle follows
a quadratic curve, write an equation if
the height is 5 feet long and the length
is 14 feet long. Show your work in the
sketchpads below.
Answer:
[tex]y= -\frac{5}{49}x^{2}+5[/tex]
Step-by-step explanation:
In order to solve this, we need to start by drawing a sketch of what the problem looks like (see attached picture).
From the picture, we can see that the graph of the equation should be a parabola with a vertex located at the point (0,5) and x-intercepts located at (-7,0) and (7,0) respectively.
So, there are two ways in which we can build a quadratic equation:
Standard form:
[tex]y=ax^{2}+bx+c[/tex]
or
Vertex form:
[tex]y=a(x-h)^{2}+k[/tex]
Since we already have the vertex and two points on the equation, we can directly use the vertex form. Where vertex is located at the coordinates (h,k)
So in this case: h=0 and k=5, which simplifies our equation a lot:
[tex]y=a(x-0)^{2}+5[/tex]
[tex]y= ax^{2}+5[/tex]
So we only need to find the value of a for our equation to be complete. We can use either x-intercept to find this. Let's use the point (7,0) so we get:
[tex]0=a(7)^2+5[/tex]
and now we can solve for a:
[tex]-5=49a[/tex]
[tex]a=-\frac{5}{49}[/tex]
so this completes our equation:
[tex]y= -\frac{5}{49}x^{2}+5[/tex]
whose graph looks like the one in the attached picture.
