The statement about the range of the logarithmic function F(x) = log_bx being positive real numbers is false; the range includes all real numbers.
The statement that the range of F(x) = logbx is the set of all positive real numbers is False. The range of a logarithmic function like F(x) = logbx, where b is the base and x is the argument, is actually all real numbers, not just the positive ones. This is because you can take the log of any positive number, but the result can be any real number, negative, positive, or zero (when x=1).
For example, if the base b is greater than 1, as x approaches zero from the positive side, logbx will approach negative infinity, illustrating how the range includes negative numbers.
6/10 + 20/100 = 8/10
6/10 can be simplified but we don't need to worry about it right now. We only need to worry about simplifying 20/100:
20/100 → 10/50 → 5/25 → 1/5
Find common denominators
1/5 → 2/10
6/10
Now, add.
6/10 + 2/10 = 8/10
Therefore, the equation is true.
Best of Luck!

please help show steps plz
Answer:
x=-17 and x=-19
Step-by-step explanation:
-17+18=1
-19+18=-1
|-1| =1
Answer:
-17 and -19
Step-by-step explanation:
Absolute value equations have two problems and two solutions unless the original answer equals a negative-then it would be no solution.
x + 18 =1 subtract 18 from both sides to get x by itself
x = 1-18
x= -17
x +18 = -1 subtract 18 from both sides to get x by itself
x= -1 -18
x= -19
pauline uses 2/5 of a cup of sugar in each batch of cookies.Yesterday, pauline used 1 cup of sugar .How many batches of cookie did pauline make yesterday?
Answer:
Step-by-step explanation
two and a half batches?
Final answer:
Pauline used 1 cup of sugar and each batch of cookies requires 2/5 cup. By dividing 1 cup by 2/5 cup, we get 2.5 giving us ≈2 batches.
Explanation:
The question asks how many batches of cookies Pauline was able to make if she used 1 cup of sugar, with each batch requiring 2/5 of a cup of sugar. To find this, we can use a simple division process as our conversion factor. You divide the total amount of sugar used by the amount needed per batch.
Steps to calculate the number of batches:
Pauline uses 2/5 of a cup of sugar for each batch of cookies.
She used a total of 1 cup of sugar yesterday.
To find the number of batches made, divide the total amount of sugar by the amount per batch: 1 cup / (2/5 cup per batch) = 5/2 = 2.5 batches.
However, since you cannot make half a batch of cookies, Pauline must have made 2 batches.

Which is equal to sin of angle e?
a) cos of angle D
b) cos of angle F
c) sin of angle D
d) sin of angle F
Answer:
B) cos f
Step-by-step explanation:
sin e = DF/EF
cos d = (which side is adjacent i don't even know)/EF
cos f = DF/EF
sin d = opposite (hypotenuse)/hypotenuse, doesn't make sense
sin f = DE/EF

Kevin has 30% less money than Erin. Kevin has $140. How much money does Erin have
Answer:
Erin has $200
Step-by-step explanation:
Kevin = K
Erin = E
30% of Erin = 0.3E
K = E - 0.3E
K = 140
Substitute
140 = E - 0.3E
140 = 0.7E
Divide both sides of the equation by 0.7
E = 200
Erin has $200

Stephen got a new job through an employment agency. The job pays $41,236 per year. The agency fee is 15% of the first 5 weeks pay.
How much will Stephen pay to the agency?
Answer:
$594.75
Step-by-step explanation:
Given
yearly salary of Stephen= $41,236
No of weeks in a year = 52
Therefore, one week salary of Stephen = $41,236/52 = $793
to get one week salary divide total salary by number of weeks
5 weeks salary of Stephen = 5*793 = $ 3,965
agency fees = 15% of Stephen's 5 week salary
(15/100)*($ 3,965) = $594.75
Therefore, Stephen has to pay $594.75 to the agency.

A guitar shop is offering two deals on their guitars. Each guitar is $50 less than its initial sale price. In addition, customers receive a further discount of $3 off each $5 of the sale price. Write a function that represents the final price of a guitar f(x) with an initial price of x. If a guitars initial price was $200, what would it be with the discount?
Answer:
30 dollar discount
Step-by-step explanation:
Using the discount parameters given, the final sale price function of the guitar would be f(x) = x - 0.6x - 30 and the discount on initial price of $200 would be $90
Let initial price = x
First discount :
$50 off :
f(x) = x - 50Second discount :
$3 off each $5 of sale price
3/5 of sale price = 0.6 × (x - 50)Final discount :
0.6( x - 50) = 0.6x - 30The Final sale price :
f(x) = x - 0.6x - 30
Given an initial price, x = 200
Discount on price :
Final discount = 0.6x - 30
Discount on price of x = 200 :
0.6(200) - 30
120 - 30 = $90
Therefore, the discount on the price is $90

Given that the measure of ∠x is 120°, and the measure of ∠y is 60°, find the measure of ∠z.
Answer:
60 degrees
Step-by-step explanation:
angle y is vertically opposite to angle a, (we can call it.)
angle x is supplementary to the other angle inside the triangle, which we can call angle b.
so, angle a is 60 degrees, as vertically opposite angles are equal
angle b is 60 degrees as supplementary angles = 180
based of the sum of angles in a triangle is 180 theorem;
60+60+unknown= 180
so unknown is 60 degrees
What is the distance between the points (4,-2) and (-1,10)?
A. 5 units
B. 6 units
C. 12 units
D. 13 units
Answer:
D. 13 units
Step-by-step explanation:
The distance between the points (4,-2) and (-1,10) is 13 units.
Explanation:To find the distance between two points, we can use the distance formula. The distance formula is:
d = sqrt((x2 - x1)^2 + (y2 - y1)^2)
In this case, the coordinates of the first point are (4, -2) and the coordinates of the second point are (-1, 10). Plugging these values into the distance formula, we get:
d = sqrt((-1 - 4)^2 + (10 - (-2))^2) = sqrt((-5)^2 + (12)^2) = sqrt(25 + 144) = sqrt(169) = 13 units
Therefore, the distance between the points (4, -2) and (-1, 10) is 13 units.

y = 4x + 11
y = -2x - 1
Answer:
x = -2, y= 3
Step-by-step explanation:
y = 4x + 11
y = -2x - 1
Because both equations are equal to y, we can set them equal to each other
4x + 11 = -2x - 1
Add 2x to each side
4x+2x +11 = -2x+2x -1
6x +11 = -1
Subtract 11 from each side
6x+11-11=-1-11
6x = -12
Divide each side by 6
6x/6 = -12/6
x = -2
Now we need to find y
y = -2x-1
y = -2(-2)-1

The sum of two numbers is 38. The smaller number is eight less than the larger number. What are the numbers?
Answer: 15 + 23 =38
So n + n + 8 = 38
which means n + n = 30
and since the n's are the same, you just cut the 30 in 2 equal pieces. 15 and 15.
So n = 15, n + 8 = 23
15 + 23 = 38 :)
What integers are plotted on the number line below?
Hey there!
We can see on this number line that each tick mark represents one because every five marks, there is a difference of five.
Two marks to the left of 0 will be 0 minus 2, so -2.
Three marks to the left of -5 will be -5 minus 3, so -8.
Your answer is -8 and -2.
Hope this helps!
Final answer:
The integers that are being referred to are -8 and -2, which are negative whole numbers located on the left side of zero on a number line.
Explanation:
When plotted on the number line, integers represent whole numbers that can be positive, negative, or zero.
To identify the integers that are plotted, one would look for distinct marks or points on the number line that correspond to whole numbers.
Based on the data, we come to the conclusion that the numbers in question are -8 and -2.
The integers plotted on the number line are -8 and -2. The integer -8 is to the left of -2 on the number line.
These two numbers are examples of negative integers, which are located to the left of zero on a standard number line. The understanding of how to read a number line and identify the placement of integers is a key concept in mathematics, which allows for better comprehension of more complex mathematical ideas such as rational numbers, real numbers, and complex numbers.
