Answer:
y = -7/3x + 5
Step-by-step explanation:
7x + 3y = 15
- subtract 7x from both sides
3y = -7x + 15
- divide both sides by 3
y = -7/3x + 5

find the equation of the linear function represented by the table below in slope-intercept form. picture of table is below
Answer:
[tex] y = 3x + 2 [/tex]
Step-by-step explanation:
The equation of a linear function in slope-intercept form is: y = mx + b, where, m = slope, and b = y-intercept.
Find slope (m) of the linear function by using any two points, say (3, 11) and (7, 23):
[tex] m = \frac{y_2 - y_1}{x_2 - x_1} = \frac{23 - 11}{7 - 3} = \frac{12}{4} = 3 [/tex]
To find the y-intercept (b), substitute the value of the corrdinate pair of any of the points represented on the table, and the value of the slope (m) into [tex] y = mx + b [/tex].
Substituting, x = -1, y = -1, m = 3.
[tex] y = mx + b [/tex]
[tex] -1 = 3(-1) + b [/tex]
[tex] -1 = -3 + b [/tex]
Add 3 to both sides
[tex] -1 + 3 = b [/tex]
[tex] 2 = b [/tex]
[tex] b = 2 [/tex]
Substitute m = 3, and b = 2 into the equation of the linear function in slope-intercept form:
[tex] y = mx + b [/tex]
[tex] y = 3x + 2 [/tex]

Select an example from the list below which correctly demonstrates that a relation does not need to be a function to have a domain and range.
A. The relation {(−1, 1), (0, 2), (3, −2), (5, 2)} is not a function, but the relation has a domain of {−1, 0, 3, 5} and a range of {1, 2, −2}.
B. The relation {−1, 0, 3, 5} is not a function and has no domain or range.
C. The relation {(0, 1), (0, 2), (0, 3), (0, 4)} is not a function, but the relation has a domain of {1, 2, 3, 4} and a range of {0}.
D. The relation {(0, 1), (0, 2), (0, 3), (0, 4)} is not a function, but the relation has a domain of {0} and a range of {1, 2, 3, 4}.

Answer:
59 degrees (just taking a shot)
Step-by-step explanation:
A six sided polygon should have a total degree total of 720 degrees. 105+142+140+124+88+x=720. When you find x, it should equal 121 degrees. Since x and y are both on a straight line, that line has to be 180 degrees. These are supplementary angles. 180-121 should equal 59.

2. During typhoon Ambo, PAGASA tracks the amount of accumulating rainfall. For
the first three hours of typhoon, the rain fell at a constant rate of 25mm per
hour.
The typhoon slows down for an hour and started again at a constant rate of 20 mm
per hour for the next two hours. Write a piecewise function that models the amount
of rainfall as function of time.
Answer:
The answer is below
Step-by-step explanation:
Let t represent the time in hour and A(t) represent the amount of accumulating rainfall at time t.
In the first three hours the rain fell at a constant rate of 25mm per
hour, hence:
A(t) = 25t 0 ≤ t ≤ 3
The rain then slows down and remains constant at 75 mm [i.e. 25(3)] for an hour.
The rain increases at a rate of 20t from 4 ≤ t ≤ 6. Hence the piecewise equation is given as:
[tex]A(t)=\left \{ {{25t\ \ \ \ \ \ \ \ \ \ for\ 0\leq\ t\ \leq\ 3} \atop {75\ \ \ \ \ \ \ \ \ \ for\ 0\leq\ t\ \leq\ 6 \atop {75+20(t-4)\ \ for\ 4\ \leq\ t\ \leq\ 6}} } \right. \\\\\left[/tex]

The 250m between Sam's house and the tennis court corresponds to 5 cm on a town map. What is the actual distance between Sam's school and the library if they are 8.4 cm apart on the same map?
Answer:
420m
Step-by-step explanation:
250m = 5cm
50m = 1cm
? = 8.4cm
50 x 8.4=
420m = 8.4cm
Step-by-step explanation:
firstly we need to find the scale factor
firstly we know that 250m=25000cm
25000/5=5000
so 1:5000 is scale factor.
Now let us find the distance between Sam's school and the library
if they are 8.4 cm apart on map it means that in actual distance they are
(8.4)*5000=42000 cm in reality

Two ratios that are equivalent to 2:12
One equivalent ratio is 1:6
To get this ratio, you divide both parts of 2:12 by 2
2/2 = 1
12/2 = 6
So that's why 2:12 is equivalent to 1:6
From here we could multiply both parts by say 3
1*3 = 3
6*3 = 18
Meaning that 1:6 and 2:12 are equivalent to 3:18
==============================================
Two possible answers are 1:6 and 3:18
There are infinitely possible answers

Emma is moving and must rent a truck. In addition to an initial fee, the rental company charges a fee of $2.50 per mile driven. If Emma were to drive 2 miles, the total cost would be $25. Write an equation for C,C, in terms of m,m, representing the total cost of renting the truck if Emma were to drive mm miles.
PLEASE HELP MEEEEEE!!!!
The total cost equation of renting the truck if Emma were to drive mm miles will be
C=2.5m+20
What is equation?Equation: A declaration that two expressions with variables or integers are equal. In essence, equations are questions, and attempts to systematically identify the solutions to these questions have been the driving forces behind the creation of mathematics. Simple algebraic equations with merely addition or multiplication to differential equations, exponential equations with exponential expressions, and integral equations are examples of different types of equations.Let,
C=total cost
m=number of miles
the cost function is in the form of
C=am+b
the rental company charges a fee of $2.5 per mile so a=2.5
C=2.5m+b.....................(1)
if Emma were to drive m=2 miles, the total cost would be C=25
25=2.5\c*2+b
25=5+b
25-5=b
20=b
b=20..................put it back in equation 1
C=2.5m+b

QUESTION 4 of 10: You estimate that your new business's revenue will grow at a compounded rate of 30% each month for the first 6
months. If your third month's revenue is estimated at $5,000, what is your second month's revenue? (Round to the nearest dollar.)
a) $2,945
b) $3,846
ОООО
c) $4,012
d) $4,333
Answer:b) $3,846
Step-by-step explanation:
If your third month's revenue is estimated at $5,000, then $3846.15 is second month's revenue.
What is Percentage?percentage, a relative value indicating hundredth parts of any quantity.
Given that business's revenue will grow at a compounded rate of 30% each month for the first 6 months.
Third month's revenue is estimated at $5,000.
We need to find the second month's revenue.
Let us assume the revenue of second month = x
Compounded rate = 30%
x + 30% of x = 5000
x + 0.3x = 5000
1.3x = 5000
Divide both sides by 1.3
x = 3846.15
Hence, $3846.15 is second month's revenue.

Answer: [tex][5, \infty)[/tex]
On a keyboard, you would write [5, infinity)
The square bracket means "include this value" and a curved parenthesis means "exclude this value". We cannot include infinity as it is not a number, so we always use parenthesis with either infinity.
[tex]y \ge 5[/tex] is the same as [tex]5 \le y[/tex] which is also the same as [tex]5 \le y < \infty[/tex] which may help lead to set up the interval notation answer.
