ba - ha = c
solve for a
Answer:
h = [tex]\frac{c}{b-h}[/tex]
Step-by-step explanation:
Given
ba - ha = c ← factor out a from each term on the left side
a(b - h) = c ← divide both sides by (b - h)
a = [tex]\frac{c}{b-h}[/tex]
HURRY!! 20 POINTS!! What is the solution set of the equation x+3/x+2=3+1/x? Note: x≠0, −2
{2} {−1, 2} {−1, 1} {−1}
The solution set for the given equation is x=-1 .
Solution set is written as {-1}
for better understanding check the calculation below.
Calculation :We need to solve the given equation
[tex]\frac{x+3}{x+2} =3+\frac{1}{x}[/tex]
To solve any equation we take LCD.
LCD of the given equation is x(x+2)
Multiply LCD with each term to remove the denominator
[tex]\frac{x+3}{x+2}\cdot x(x+2) =3\cdot x(x+2)+\frac{1}{x}\cdot x(x+2)\\x(x+3)=3x(x+2)+x+2\\x^2+3x=3x^2+6x+x+2\\[/tex]
Subtract x^2 and 3x from both sides of the equation to get 0 on the left side of the equation
[tex]0=3x^2+6x+x+2-x^2-3x\\0=2x^2+4x+2\\[/tex]
Now divide the whole equation by 2 and then we factor it
[tex]0=x^2+2x+1\\0=(x+1)(x+1) \\x+1=0\\x=-1[/tex]
The solution set for the given equation is x=-1
Solution set is written as {-1}

Write 4-6 sentences describing how many acute and obtuse angles are created when 2, 3, or 4 parallel lines are crossed by a single transversal that is not perpendicular to them. Identify how many unique acute angle measures there are and how many unique obtuse angle measures there are, explaining your reasoning. Propose a generalization for when there are n parallel lines, and confirm the generalization matches what was found for the cases of 2, 3, or 4 parallel lines. Prove the generalization, explaining all of your reasoning.

A sculptor is selling her work at an exhibit and hopes to earn at least $31,000 in revenue. Small pieces go for $780 and large pieces go for
$1,500.
If x represents the number of small pieces sold and y represents the number of large pieces sold, write an inequality that
describes this situation.
The answer should be
780x + 1500y=31000
please correct me if i'm wrong

write y=5/8x +6 in standard form using intergers
Answer:
5x - 8y = -48
Step-by-step explanation:
Move 5/8x to the y side to get (-5/8)x + y = 6. Multiply both sides by -8 to get 5x - 8y = -48.

Find the slope using a table
Answer:
-1/2
Step-by-step explanation:
slope = (y2-y1)/(x2-x1)

Presenting a graph with a skewed scale would be a:
data collection error.
Interpretation error.
sampling error.
measurement error.
Presenting a graph with a skewed scale is a data collection error. The correct option is A.
What is a data collection error?The field data collection error is the study of the erroneous sample or inaccurate data, not the study of missing data. It might be challenging to maintain a high response rate on a large-scale survey.
The answer would be a data collection error. Interpretation doesn’t have an effect on how the graph is originally graphed, and neither does measurement. Sampling could be an answer, however, data collection makes more sense.
Hence, the correct option is A.

I REALLY NEED THIS RIGHT NOW PLEASE HELP Are the given lines parallel? How do you know? y=2 and y = -4
Answer:
Yes, they have the same slope
Step-by-step explanation:
Both y=2 and y=-4 have the same slope, a slope of zero, because when they are graphed, both of them form a straight horizontal line. And since they both form a straight horizontal line, they are parallel because they have the same slope.

The hypotenuse of a right triangle is 1 centimeter longer than one side and 4 centimeters longer than three times the other side. Find the dimensions of the triangle.
Answer:
[tex]Hypotenuse = 25cm[/tex]
[tex]Opposite = 24cm[/tex]
[tex]Adjacent = 7cm[/tex]
Step-by-step explanation:
Represent:
The opposite with aThe adjacent with bThe hypotenuse with cGiven that:
[tex]c = 1 + a[/tex]
[tex]c = 4 + 3b[/tex]
Required
Solve for a, b and c
[tex]c = c[/tex]
So, we have:
[tex]1 + a = 4 + 3b[/tex]
Subtract 1 from both sides
[tex]a = 4 -1 + 3b[/tex]
[tex]a = 3 + 3b[/tex]
Apply Pythagoras Theorem
[tex]c^2 = a^2 + b^2[/tex]
Substitute 3 + 3b for a and 4 + 3b for c
[tex](4 + 3b)^2 = (3 + 3b)^2 + b^2[/tex]
Open brackets
[tex]16 + 12b+12b+9b^2 = 9 + 9b+9b+9b^2 +b^2[/tex]
[tex]16 + 24b+9b^2 = 9 + 18b+10b^2[/tex]
Collect Like Terms
[tex]10b^2 - 9b^2 + 18b - 24b + 9 - 16 = 0[/tex]
[tex]b^2 - 6b -7 = 0[/tex]
Expand
[tex]b^2 +b-7b-7=0[/tex]
Factorize:
[tex]b(b+1)-7(b+1) =0[/tex]
[tex](b-7)(b+1) = 0[/tex]
Split:
[tex]b - 7 = 0\ or\ b+1=0[/tex]
[tex]b = 7\ or\ b=-1[/tex]
But the adjacent of a triangle can't have a negative measurement.
So:
[tex]b = 7[/tex]
Recall that:
[tex]c = 4 + 3b[/tex]
[tex]a = 3 + 3b[/tex]
Substitute 7 for b in the above expressions
[tex]c = 4 + 3 * 7[/tex]
[tex]c = 4 + 21[/tex]
[tex]c = 25[/tex]
[tex]a = 3 + 3 * 7[/tex]
[tex]a = 3 + 21[/tex]
[tex]a = 24[/tex]
Hence, the dimensions of the triangle are:
[tex]Hypotenuse = 25cm[/tex]
[tex]Opposite = 24cm[/tex]
[tex]Adjacent = 7cm[/tex]

Vanessa's total sales = - $321.50 1. How much do the girls owe the school in concession fees (15%) from Vanessa's total sales?
Answer:
pretty easy i did the math and it is about 42.56
Step-by-step explanation:
The revenue, R(x), from selling x units of a product is represented by the equation R(x) = 35x, while the total cost, C(x), of making x units of the product is represented by the equation C(x) =20x +500. The total profit, P(x), is represented by the equation P(x) =R(x) - C(x). For the values of R(x) and C(x) given above, what is P(x)? *
a) 15x
b) 15x+500
c) 15x-500
d) 10x+100
Answer:
c) 15x-500Step-by-step explanation:
Step one:
given data
Revenue
[tex]R(x) = 35x[/tex]
Total cost
[tex]C(x) =20x +500[/tex]
profit
[tex]P(x) =R(x) - C(x)[/tex]
Required
the value of P(x)
Step two:
substituting we have
[tex]P(x) =35x- (20x+500)\\P(x)=35x-20x-500\\\\P(x)=15x-500[/tex]
Option C is correct

We you divide x12 and y18,12=4 y=6. Then you take +1 and change it to -1. It should bring you to answer A.

Answer:
The answer is A:
[tex](x^{4}y^{6} - 1)(x^{8}y^{12} - x^{4}y^{6} + 1)[/tex]
Step-by-step explanation:
To solve this question, first apply the exponent rule to the entire equation:
[tex]x^{12}y^{18} + 1[/tex]
[tex]= (x^{4}y^{6})^{3} + 1^{3}[/tex]
Next, we can apply the Sum of Cubes formula. To refresh your memory, the formula is as thus:
[tex]x^{3} + y^{3} = (x + y)(x^{2} - xy + y^{2})[/tex]
So, let's apply this to the equation above:
[tex](x^{4}y^{6})^{3} + 1^{3}[/tex]
[tex]= (x^{4}y^{6} + 1)((x^{4}y^{6})^{2} - x^{4}y^{6} + 1^{2})[/tex]
[tex]= (x^{4}y^{6} + 1)((x^{4}y^{6})^{2} - x^{4}y^{6} + 1^{2})[/tex]
[tex]= (x^{4}y^{6} - 1)(x^{8}y^{12} - x^{4}y^{6} + 1)[/tex]
Therefore, the answer is A.

x2 • (x2 - 32772)
Step-by-step explanation:
step 1: ((x4) - 22x2) - 32768x2
step 2: Pull out like factors :
x4 - 32772x2 = x2 • (x2 - 32772)
Factoring: x2 - 32772
Theory : A difference of two perfect squares, A2 - B2 can be factored into (A+B) • (A-B)
Proof : (A+B) • (A-B) =
A2 - AB + BA - B2 =
A2 - AB + AB - B2 =
A2 - B2
Note : AB = BA is the commutative property of multiplication.
Note : - AB + AB equals zero and is therefore eliminated from the expression.
Check : 32772 is not a square !!
Ruling : Binomial can not be factored as the difference of two perfect squares.

If A = { 2,3,5,7 } then find the value of n(A).
Answer:
We conclude that
n(A) = 4Step-by-step explanation:
Given the set
A = { 2,3,5,7 }If we closely observe, we can easily identify that set A has 4 elements, which are 2, 3, 5, and 7.
n(A) denotes the number of elements in a set.
Since set A has 4 elements, therefore the value of n(A) = 4
Thus, we conclude that
n(A) = 4
