6x - 10 = 2 ( add 10 to both sides )
6x = 12 ( divide both sides by 6 )
x = 2
Answer:
x=2
Step-by-step explanation:
Given
9x - 10 = 3x + 2 ( subtract 3x from both sides )

Answer:
x=65
Step-by-step explanation:
The angle with the measurement of 125 degrees is supplementary to the one adjacent to it (sharing the same vertex and on same line).
What that means is that the measurement of the angle adjacent to that angle of 125 degrees is 180-125=55.
So now we know the sum of the interior angles of a triangle add up to be 180 degrees.
That is we have to solve the following equation for x:
x+55+60=180
Add 55 and 60:
x+115=180
Subtract 115 on both side:
x=180-115
Simplify:
x= 65

The two triangles below are similar. What is the similarity ratio of ∆ABC to ∆DEF?
A) 3:1
B) 1:3
C) 2:1
D) 1:2
Answer:
Option C is correct
Step-by-step explanation:
The two triangles are similar if there sides are proportional to each other
So, In Triangle ABC and Triangle DEF
AB/DE=BC/EF=AC/FD
according to definition of similar triangles.
We are given AC = 8
and FD = 4
So, AC/FD = 8/4 = 2/1
or 2:1
So, Option C is correct
Answer: Option C
2:1
Step-by-step explanation:
Two triangles are similar if the ratio of their sides is proportional.
In this case we have the triangle ∆ABC and ∆DEF so for the sides of the triangles they are proportional it must be fulfilled that:
[tex]\frac{AB}{DE}=\frac{BC}{EF}=\frac{AC}{DF}[/tex]
In this case we know that:
[tex]AC=8[/tex]
[tex]DF=4[/tex]
Therefore
[tex]\frac{AC}{DF} = \frac{8}{4}\\\\\frac{AC}{DF} = \frac{2}{1}[/tex]
The similarity ratio of ∆ABC to ∆DEF is 2:1

Answer:
He didn't change the direction of the inequality when he divided both sides by -2.
Step-by-step explanation:
Let's go through each step and see.
First step: They distribute and they did so correctly. -4(x+8)=-4x-32.
Second step: They added 2x on both sides.
Third step: They added 32 on both sides.
Fourth step: The divide both sides by -2 correctly but since this is inequality you must flip the sign.
For example 3>2 but if you multiply both sides by -1 or divide both sides by -1 you get -3<-2.
You have to flip the sign whenever you multiply or divide both sides of inequality by negative number.

On a particular day, the wind added 4 miles per hour to Jaime's rate when she was rowing with the wind and subtracted 4 miles per hour from her rate on her return trip. Jaime found that in the same amount of time she could row 48 miles with the wind, she could go only 24 miles against the wind. What is her normal rowing speed with no wind?
Answer:
12 miles per hour
Step-by-step explanation:
Let her normal rowing speed be x
Also note the formula D = RT, where d is distance, R is rate(speed) and T is time
On windy day, her speed is x + 4
On against wind return, her speed is x - 4
With wind, she can go 48 miles in same amount of time when she goes 24 miles against wind. This can be written as:
48 = (x+4)T
24 = (x-4)T
We can write each equation in terms of T and equate both. So we have:
48/x+4 = T
24/x-4 = T
Thus,
[tex]\frac{48}{x+4}=\frac{24}{x-4}\\48(x-4)=24(x+4)\\48x-192=24x+96\\24x=288\\x=\frac{288}{24}\\x=12[/tex]
Thus, Jaime's normal rowing speed is 12 miles per hour
which values of x and y would make the following expression represent a real number? (4+5i)(x+yi)
Answer:
So x=4 and y=-5 would work.
Step-by-step explanation:
When you multiply complex conjugates, you get a real result.
Example:
[tex](a+bi)(a-bi)=a^2-b^2i^2=a^2+b^2[/tex]
I replace [tex]i^2[/tex] with -1 since [tex]i^2=-1[/tex].
[tex]a^2+b^2[/tex] is a real number (there is no imaginary part, no i).
So what is the conjugate of 4+5i?
4-5i
So x=4 and y=-5 would work.
A multiple of the complex conjugate would work as well.
[tex](a+bi)(ca-cbi)[/tex]
[tex]c(a+bi)(a-bi)[/tex]
[tex]c(a^2-b^2i^2)[/tex]
[tex]c(a^2+b^2)[/tex]
This is still a real number; there is no imaginary part,no i.

The measure of <2 is 45 degree.
What is Angle Sum Property?The angle sum property of a triangle states that the sum of the interior angles of a triangle is always 180 degrees.
From the figure, applying angle sum property
<2 + 45 + 90= 180
<2 + 135=180
<2 = 180- 135
<2 = 45 degree

The scale of a town map is 1 inch to 3 miles. On the map, a lake and the downtown are 4 inches apart. What is the actual distance between the lake and the downtown?
3/4 mile
1/3 mile
7 miles
12 miles
Answer:
Step-by-step explanation:
The answer is 12 miles, if every inch is 3 miles on the map then 3x4=12.
Answer:
12 miles
Step-by-step explanation:
In order to solve the problem you only have to use the scale of the map, we know that the ratio is 1 inch to 3 miles, so if one inch in the map represent 3 miles on real scale, now we just do a rule of three like this:
[tex]\frac{1 inch}{4 miles}=\frac{3 inches}{x}[/tex]
So now that we have our function we can clear the x to solve the problem:
[tex]x=\frac{3x4}{1}[/tex]
[tex]x=\frac{12}{1}[/tex]
[tex]x=12 miles.[/tex]
By doing this we now know that there are 12 miles from downtown to the lake.

Option C (f(x) = x^2)
Step-by-step explanation:
Quadratic Function is a polynomial which has a maximum degree of 2. It is expressed in the form:
f(x) = a + bx + cx^2; where a, b, and c are real numbers.
Any function which has the highest degree of 2 (not more than that) is the quadratic function. Option A illustrates the absolute values function. Option B shows a function which does not match the characteristics of the quadratic equation. Option D shows a linear function. Therefore, Option C (i.e. f(x) = x^2) is the correct choice!!!

In some trigonometry classes, this acronym is very important to solving questions like this.
Why?
It tells us the right triangle-definition of these trigonometry functions.
We have that cosine of an angle is equal to tge side that is adjacent to it over the hypotenuse.
So here we are asked to find cos(B).
Lets look at triangle respect to the angle B
The measurement of the side that is opposite is 64.
The measurement of the side that is adjacent is 48.
The measurement of the hypotenuse is 80.
So cos(B)=48/80.
Let's reduce. 48 and 80 have a common factor of 8 so divide numerator and dexter by 8. This gives us:
cos(B)=6/10.
One more step in reducing. Both factors are even so cos(B)=3/5.
Is (4y-8)cm divided by 2 equals to 4y-8cm over 2 and then a cm or is it (2y-4)cm?
Answer:
(2y-4)cm
Step-by-step explanation:
In the given question we have (4y-8) divided by 2
which can be written mathematically as [tex]\frac{\left ( 4y-8 \right )cm}{2}[/tex]
Now (4y-8) is a quatity with unit cm. and the whole expression is in parentheses. Moreover, two quatity can only be added or subtracted only when their units are same. Therefore 4y and 8 must have same unit that is cm.
Therefore, [tex]\frac{\left ( 4y-8 \right )cm}{2}=(2y-4)cm[/tex] and not anything else

[tex]3 \le x \le 7[/tex].
Step-by-step explanation:
Hopefully this will help. Let me know in the comments if it doesn't.
The domain is all the x's where the function exists. The function you have starts at x=3 and ends at x=7. There are no breaks in your line between those numbers for x. So your domain is all x's between 3 and 7 ( inclusive).
So that means all values of x that is greater than or equal to 3 and values of x less than or equal to 7.

Which logarithmic equation has the same solution as x-4=2^3
Answer:

Step-by-step explanation:
The given equation is:
[tex]x-4=2^{3}[/tex]
We have to find the logarithmic equation with same solution as the given equation.
If we take the log of both sides, we can get a logarithmic equation. Since the log operation is applied to both sides the solution of the equation will stay the same.
Taking the logarithm to the base 3 of both sides, we get:
[tex]log_{3}(x-4)= log_{3}(2)^{3}\\\\ log_{3}(x-4)= 3log_{3}(2)[/tex]
Answer: The CORRECT answer is C: log2(x-4)=3
