Answer:
Lets name the first set A and the second one B.
The union:
A∪B = {-7,0}∪{-3,5} = {-7, -3, 0, 5}The intersection:
A∩B = {-7,0}∩{-3,5} = ∅ as no common elementsExplain??????????????????
Answer:
20
Step-by-step explanation:
You just replace the numbers in the letters
So it becomes: 9/3 + 2×6 + 5
You then simplify it to: 3 + 12 + 5
Work your way from there: 15 + 5= 20
So your answer is 20

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

12. Negative twelve is four less than twice a number, p.
Answer:
tyrr
Step-by-step explanation:
g
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.

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
17 x 30 = 510 Not correct as calculated before taxes.
100-80/ 100 = 0.8
0.8 x 510 = 408
408/510 = 0.8 Is correct
0(17) (30) = 510 Not correct as calculated before tax
510 - 2(17)(30) = 510 i Not correct as calculated before tax.

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

Solve the equation for y.
-4x+ 3y = 12
Answer:
[tex] - 4x + 3y = 12 \\ 3y = 12 + 4x[/tex]
divide through out by 3:
[tex]y = 4 + \frac{4}{3} x \\ \\ { \boxed{ \boxed{y = \frac{4}{3}x + 4 }}}[/tex]
Answer:
y = 4/3x + 4
Step-by-step explanation:
-4x + 3y = 12
-4x + 3y + 4x = 12 + 4x
3y = 4x + 12
3y/3 = (4x + 12)/3
y = 4/3x + 4

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.
