Answer:
amt of 25% solution to mix=6 gal
amt of 40% solution to mix=3 gal
Step-by-step explanation:
let x=amt of 25% solution to mix
9-x=amt of 40% solution to mix
25%x+40%(9-x)=30%*9
.25x+3.6-.40x=2.7
.15x=0.90
x=6

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.

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.
___ student(s) for every 8 computers.
45 students for every __ computer(s).
Answer:
_18__ student(s) for every 8 computers.
45 students for every _20_ computer(s).
Step-by-step explanation:
18 students for every 8 computers 45 students for every 20 computersSolve 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 table below represents a function.
x y
0 1
2 5
5 26
7 50
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
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).
