Solve the equation for h and r. x= r-h/y
[tex]r \times x = \frac{r - h}{y} \\ [/tex]
Multiply sides by y
[tex]r \times x \times y = r - h[/tex]
Subtract sides minus r
[tex]r \times x \times y - r = - h[/tex]
Multiply sides by -1
[tex] - r.x.y + r = h[/tex]
Factoring r
[tex]h = r(1 - x.y)[/tex]

The value of y varies directly with x. When y= 2 4/7, x= 37 .
What is the value of y when x is 27 ?
1 5/7
2 3/7
3 1/7
3 4/7
Answer:
Option (a).
Step-by-step explanation:
The value of y varies directly with x. It would mean that,
y=kx, where k is constant
When
[tex]y=2\dfrac{4}{7},x=\dfrac{3}{7}\\\\y=\dfrac{18}{7}, x = \dfrac{3}{7}[/tex]
then,
[tex]\dfrac{18}{7}=k\times \dfrac{3}{7}\\\\k=6[/tex]
When x = 27,
[tex]y=6\times \dfrac{2}{7}\\\\y=\dfrac{12}{7}\\\\\text{or}\\\\y=1\dfrac{5}{7}[/tex]
So, the value of y is [tex]1\dfrac{5}{7}[/tex] when x is 27.

Consider the statement "Two lines in a coordinate plane are parallel if and only if the slopes of the lines are m and m, where m is any real number." Is this statement true or false? Explain your reasoning.
Statement is true.
The slopes of parallel lines are equal. Note that two lines are parallel if their slopes are equal and they have different y-intercepts.
Their:
1. corresponding angles are equal.
2. Alternative interior angles are equal.
3. Consecutive interior angles are supplementary.
4. Consecutive exterior angles are supplementary.

Find the constant. quickly please!
Answer:
Assuming you are asking for the slope which is 3 or in the equation format y=3x
Step-by-step explanation:
you must find the distance in the y- values and the x values, how each value increases or decreases. You may have heard of the phrase rise/run. To get to the pint (2,6) from (1,3), you must rise 3 units and move 1 unit. If you were to follow the rise/run method, you will need to divide the two numbers. In this case you will be dividing 3/1 which equals you. Then you must plug that number into the formula (y=mx+b).

The table below represents a function.
x y

Which equation makes the table true?
f( x) = 2 x + 1
f( x) = x 2 + 1
f( x) = x 2 - 1
f( x) = 2 x - 1
Answer:
f( x) = x ^2 + 1
The equation f( x) = x² + 1 makes the table true.
What is equation?Two or more expressions with an equal sign is called as equation.
The given table is
x y
0 1
2 5
5 26
7 50
The table value satisfy with the function f( x) = x² + 1=y
if x=0, then y=f(0)=0² + 1=1
if x=2, then y=f(2)=2² + 1=4+1=5
if x=5, then y=f(5)=5² + 1=25+1=26
if x=7, then y=f(7)=7² + 1=49+1=50
Therefore f(x)=x² + 1 is the equation of table.

Solve the equation x2 + + 7x= 30
O A. x= 15 and x= -2
0 B x=-6 and x = 5
0 C x= -10 and x= 3
O D. x= 10 and x= -3
Answer:
x^2+7x=30
x^2+7x-30=0
Here a=1,b=7 and c=-30
Now,
Discriminant(D)=b^2-4ac
=7^2-4×1×(-30)
=49+120=169
By applying Quadratic formula
x=-b+- root over b^2-4ac÷2a
=-7+- root over D ÷ 2×1
=-7 +- root over 169 ÷2
=-7 +- 13 ÷2
Now,
Either x=-7+13÷2=6÷2=3
Or x=-7 -13 ÷2=-20÷2=-10
Hence, ans is (C) x=-10 and x=3
A local jewelry store sells class rings. The store engraves a name and date on the ring and sells it using a markup rate of 340%. Write an equation that can be used to find the amount of markup y on the cost of a ring x.
The proportional equation that can be used to find the amount of markup y on the cost of a ring x is given by:
[tex]y = 3.4x[/tex]
What is a proportional relationship?A proportional relationship is a function in which the output variable is given by the input variable multiplied by a constant of proportionality, that is:[tex]y = kx[/tex]
In which k is the constant of proportionality.In this problem, the markup rate is of 340%, hence [tex]k = \frac{340}{100} = 3.4[/tex].

Answer:
Charles: 17 points
Adam: 25 points
Bethany: 30 points
Answer:
Adam scored 25 points.
Bethany scored 30 points.
Charles scored 17 points.
Step-by-step explanation:
A = Adam, B = Bethany, C = Charles
What we know:
C + 8 = A
A + 5 = B
A + B + C = 72
Charles:
C + 8 + 5 = B
C + (C + 8) + (C + 13) = 72
72 - 8 - 13 = 51
51/3 = 17
Charles scored 17 points.
Bethany:
17 + 13 = 30
Bethany scored 30 points.
Adam:
17 + 8 = 25
Adam scored 25 points.
