The result of dividing a two-digit number by the number with its digits reversed is 7 over 4. If the sum of the digits is 12, what is the number?
Why does a fraction with lesser denominator have larger pieces than the fraction with a greater denominator
Answer:
Step-by-step explanation:
The bigger the denominator the smaller the fraction.
For example if you have 1/9 and 1/5.
The fraction 1/5 has a greater denominator and is greater than 1/9, because it is split into less parts.
Hope this helped :)
4.A system of equations is shown below. Find the solution by using substitution. y = 3x + 6 y = x + 2 O (0,2) 0 (0,-2) O (2,0) O (-2, 0)

0,2
Step-by-step explanation:
Jordan says that the shortest side
of any isosceles triangle has to be
at least 6 units, but Tierra says
there is no minimum length for the
shortest side of an isosceles
triangle. Who is right? Why?
Answer: I'm pretty sure Tierra is right because an isosceles triangle does not have a minimum side length. It's just the shortest length has to be equal to the other shortest length.
Step-by-step explanation: properties of an isosceles triangle.
What is the slope of the line that passes through the points (1, -7) and (1, 13)?
Write your answer in simplest form.
Answer:
Undefined
Step-by-step explanation:
An expression in mathematics which does not have meaning and so which is not assigned an interpretation. For example, division by zero is undefined in the field of real numbers.
Solve the system of linear equations by substitution.
x + 4y = 21
y = −x + 12
the solution to the system is ( , ) answer is an ordered pair
=========================================================
Explanation:
We can replace y in the first equation with -x+12 due to the second equation.
x+4y = 21
x+4( y ) = 21
x + 4(-x+12) = 21
x-4x+48 = 21
-3x = 21-48
-3x = -27
x = -27/(-3)
x = 9
which leads to,
y = -x+12
y = -9+12
y = 3
Therefore, the solution as an ordered pair is (x,y) = (9, 3)
---------------
Check:
x+4y = 21
9+4(3) = 21
9+12 = 21
21 = 21 .... the first equation works
and,
y = -x+12
3 = -9+12
3 = 3 ... so does the second equation
Both equations are true for those x and y values. The answer is fully confirmed.

Answer:
30
Step-by-step explanation:
To work this out we do:
6÷20%
6÷0.2
30
This makes sense since 20% of 30 will be 10%(3) ×2 = 6
Answer:
30
Step-by-step explanation:
Equation ---> 6 = 20%
to get to 100% you multiply 20% by 5.
20% x 5 = 100%
So you do the same to the other side of that equation
6 x 5 = 30
6 is 20% of 30

C(x) = (12,000x - 0.02x^3) - (3000x - 0.002x^3)
Write a simplified expression for C(x).
A. C(x) = -0.022x^3 + 9000x
B. C(x) = -0.018x^3 + 9000x
C. C(x) = -0.022x^3 + 15,000x
Answer:
B
Step-by-step explanation:
C(x) = (12,000x - 0.02x^3) - (3000x - 0.002x^3)
C(x) = 12,000x - 0.02x^3 - 3000)x + 0.002x^3
C(x) = (12,000 - 3,000)x + (-0.02 - 0.002)x^3
= 9000x - 0.018x^3

Answer:
The functions have the same y-intercept.
OPTION C is correct.
Step-by-step explanation:
DEFINITIONS AND FORMULAS
The equation of a linear graph is given to be:
[tex]y=mx+b[/tex]
Where m is the slope of the graph and b is the y-intercept.
To calculate the slope given a table, we can use the formula:
[tex]m=\frac{y^{2}-y^{1} }{{}x^2 -x^1}[/tex]
SOLUTION
Function 1: The equation of the graph is given to be
[tex]p=-\frac{3}{2}r-5[/tex]
Therefore, the y-intercept of the graph is given to be:
[tex]b=-5[/tex]
Function 2: Recall that the y-intercept of a graph is the y-value when x = 0.
On checking the graph, we can see that when r = 0, p = -5.
Therefore, the y-intercept is:
[tex]b=-5[/tex]
ANSWER
The functions have the same y-intercept.
OPTION C is correct.
this took me awhile but the answer is function 1
Step-by-step explanation:
Which equation represents exponential growth?
O A) y= 2x
O B) y = 3(5)
OC) y = 4x?
OD) y = 2(0.5)
Answer:
C) y = 4x?
Step-by-step explanation:
Exponential growth is a process that increases quantity over time. It occurs when the instantaneous rate of change of a quantity with respect to time is proportional to the quantity itself.
There are two types of exponential functions: exponential growth and exponential decay. In the function f (x) = bx when b > 1, the function represents exponential growth. In the function f (x) = bx when 0 < b < 1, the function represents exponential decay

Answer:
In response to tissue injury, the body initiates a chemical signaling cascade that stimulates responses aimed at healing affected tissues. These signals activate leukocyte chemotaxis from the general circulation to sites of damage. These activated leukocytes produce cytokines that induce inflammatory responses [7].

what do you add to 35 over 8 to make 6
Answer:
You would add [tex]\frac{13}{8}[/tex] or 13/8 (fraction)
Step-by-step explanation:
First we make an equation with the following evidence:
We know 35 over 8 is [tex]\frac{35}{8}[/tex]
And we know were trying to get 6
The unknown is the "add" which gives us X
Equation: x + [tex]\frac{35}{8}[/tex] = 6
When we solve the equation we get x = 13/8
How do we solve it?
Subtract 35/8 on both sides:
x + 35/8 -35/8 = 6 - 38/8
And leaves us with x = 6
