Answer:
-1.6
Step-by-step explanation:
Since they're both negative and you're adding, you would do the same if you added normally, but you would add a negative sign.
Answer:
-2.6
Step-by-step explanation:
-1.4 + (-1.2)
-1.4 - 1.2
-(1.4+1.2)

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

Step-by-step explanation:
When we get a sale value or reduced value to find
This is a short cut of workings in bold to find correct value.
10% of 510 = 51
20% of 510 = 102
510-102 =408

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.

2) The y coordinate stayed the same between the image and pre-image, but the x-coordinates decreased by 7.
Step-by-step explanation:
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

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

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)

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

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 equation to represent the given phrase is 2p-4=-12.
What is an equation?In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
The given phrase is "Negative twelve is four less than twice a number, p."
Here, four less than twice a number, p is
2p-4
The difference is equal to -12.
Now, 2p-4=-12
The solution of an equation is the set of all values that, when substituted for unknowns, make an equation true.
Here, transpose -4 to the other side of an equation, we get
2p=-12+4
2p=-8
p=-2
Therefore, the value of p is -2.
