Answer:
no
Step-by-step explanation:
The two short sides, 1 and 2, do not have a sum greater than the long side, 5, so these lengths do not form any sort of triangle.
__
Lengths 1, 2, √5 satisfy the Pythagorean theorem, so will form a right triangle.
1² +2² = (√5)²
1 + 4 = 5 . . . . . . Pythagorean theorem is satisfied

7b^2- b + 3b + 6 - 3b^2+ 5 + 2b^2+ 7b
Answer:
Below
Step-by-step explanation:
First we combine your first set of terms,
7b^2 + 2b^2 = 9b^2
There's a subtraction hidden in there!
9b^2 - 3b^2 = 6b^2
Next we do the same thing for the second term,
3b + 7b = 10b
but there's a subtraction in the expression!
10b - b = 9b
Then we finish with our third term
6 + 5 = 11
Answer:
6b^2 + 9b + 11

Hi there!
(z)
We know that the two segments with "z" are congruent, so:
z + 15 = 5z + 9
Solve for z:
15 = 4z + 9
6 = 4z
z = 3/2
(y)
We know that (7y + 6) = 90° (indicated by the square angle), so:
7y + 6 = 90
7y = 84
y = 12°
(x)
Segments (x + 26) and (3x - 8) are congruent, so:
x + 26 = 3x - 8
26 = 2x - 8
34 = 2x
x = 17

Step-by-step explanation:
Job A: $8.95 per hour (40 hours a week)Job B: $16,400 per year
a. Which job pays more?
b. How much more?
Answer:
A) Job A pays more.
B) $784 dollars more than job B.
Step-by-step explanation:
We know that job B Makes $16,400 per year. We just need to find out how much job A makes in a year.
Job A: 8.95 x 40= $358 in a week.
We know that there is 4 weeks in a month and 12 months in a year.
12 x 4 = 48.
48 weeks in a year x $358 in a week= $17,184
We now know that job A pays more than iob B.
In order to find out how much more we will use the formula Job A- Job B= Difference between.
$17,184-$16,400= $784
Job A pays $784 dollars more than job B.

The accompanying data set lists the numbers of children of world leaders. Use the data to construct a frequency distribution using six classes and to create a frequency polygon. Describe any patterns.
Frequency polygons are used to show the trend between the elements of a given dataset and the frequency of each element.
From the dataset, we have the following class of 6 and the frequency:
[tex]Class \to Frequency[/tex]
[tex]0 - 2 \to 9[/tex]
[tex]3 - 5 \to 18[/tex]
[tex]6 - 8 \to 7[/tex]
[tex]9 - 11\to 0[/tex]
[tex]12 - 14 \to 5[/tex]
[tex]15 - 17 \to 4[/tex]
So, the frequency distribution is as follows:
[tex]\begin{array}{ccc}{Class}&{Frequency}&{x}\\0-2&9&1\\3-5&18&4\\6-8&7&7\\9-11&0&10\\12-14&5&13\\15-17&4&16\end{array}\right][/tex]
The class midpoint (x) is calculated by calculating the mean of each class.
For instance, the midpoint (x) of class 0 - 2 is:
[tex]x = \frac{1}{2}(0+2) = \frac{1}{2} \times 2 =1[/tex] ---- and so on
The class midpoint (on the x-axis) is plotted against the frequency (on the y-axis) to create the frequency polygon (see attachment)

Your printer takes 36 seconds to print a small photo and 60 seconds to print a large one.
a.) Write an expression for the time (in seconds) your printer would take to print a batch
including both small and large photos.
b.) Find the time your printer would take to print 12 small photos and 5 large photos.
Answer: for part B = 732 seconds or 12.2 minutes
Step-by-step explanation: 36 seconds times the amount of small photos 12 = 432 plus 60 seconds times the amount of large 5 photos = 300 , 432 plus 300 equals 732 seconds
(36 x 12) + (60 x 5) = 732
Jae is a real estate photographer. The amount he earns in one week is a linear function of the number of houses he photographs.
If he photographs 2 houses, he earns $315, and if he photographs 7 houses, he earns $1015.
a. Create a linear model for Jae's earnings (y) (in dollars) as a function of the the number of houses he photographs (x), and put
the model in slope-intercept form.
Equation of a linear function is defined by equation y = mx + b,
where m = slope of the line and b = y-intercept
Linear model representing a function for the earning (y) to photograph the houses (x) will be,
y = 140x + 35
Let the linear equation representing the earnings to photograph the houses,
y = mx + b
If we graph a line with two variables, earnings from photography on y-axis and the number of houses at x-axis,
Slope of the line 'm' = [tex]\frac{\triangle y}{\triangle x}[/tex]
If two points lying on the line are (2, 315) and (7, 1015).
Slope of the line 'm' = [tex]\frac{1015-315}{7-2}[/tex]
= [tex]\frac{700}{5}[/tex]
= 140
Therefore, equation of the line will be,
y = 140x + b
Since, (2, 315) lies on the line,
315 = 140(2) + b
315 = 280 + b
b = 35
Now the equation will be,
y = 140x + 35
Therefore, linear model representing a function of the earning (y) to photograph the houses (x) will be,
y = 140x + 35

Solve f(x) = 2 for x.
f(x)=2
f(x) is the function, x inside represent the input, while the value the function is equal to is the output.
So to solve for x, look at where f(x)/ y is equal to 2. And, from there the function is equal to 2 when x=-1.
So your answer is x=-1

Paul bought a student discount card for the bus. The card allows him to buy daily bus passes for $1.40.
After one month, Paul bought 19 passes and spent a total of $31.60.
How much did he spend on the student discount card?
Paul spent $________
on the student discount card.
Answer:
$5
Step-by-step explanation:
First, we need to find the total amount he spent on the passes.
We just need to multiply the number of passes by the price of each pass.
19 x 1.4 = 26.6
This means he spent $26.6 on the passes.
Now, we can find out how much he spent on the discount card.
Just subtract his total spending amount by the amount he spent on passes.
31.6 - 26.6 = 5
He spent $5 on the discount card.
