Using it's concepts, the domain and the range of the function are given as follows:
a) Domain: [0, 7].
b) Range: [0, 300].
What are the domain and the range of the function?The domain of a function is composed by the set of all possible input values of the function. Hence, on the graph, the domain is composed by the values of x.
In the context of this problem, the input of the function is the number of days. A week has 7 days, hence the domain of the function is given by:
[0, 7].
The range of a function is composed by the set of all possible output values of the function. Hence, on the graph, the range is composed by the values of y.
In the context of this problem, the output of the function is the balance of the bank account after each day. Supposing that the smallest balance of the account is of $0, and considering the greatest balance of $300 stated in the problem, the range of the function is given by:
[0, 300].
What is the missing information?The graph of the function is incomplete, hence we suppose that the minimum balance is of $0.

What is the general form of the equation of the line shown?
y
2 x-y+ 3 = 0
2 X-Y-3 = 0
ox-2y-3=0
Answer:
Sorry for late response, but I believe it may be 2x - y - 3 = 0.
Step-by-step explanation:
The general form of the equation of the line shown is,
⇒ y = - x + 3
What is Equation of line?The equation of line in point-slope form passing through the points
(x₁ , y₁) and (x₂, y₂) with slope m is defined as;
⇒ y - y₁ = m (x - x₁)
Where, m = (y₂ - y₁) / (x₂ - x₁)
Given that;
Two points on the line are (2, 1) and (0, 3).
Now,
Since, The equation of line passes through the points (2, 1) and (0, 3).
So, We need to find the slope of the line.
Hence, Slope of the line is,
m = (y₂ - y₁) / (x₂ - x₁)
m = (3 - 1)) / (0 - 2)
m = 2 / - 2
m = - 1
Thus, The equation of line with slope - 1 is,
⇒ y - 1 = - 1 (x - 2)
⇒ y - 1 = - x + 2
⇒ y = - x + 2 + 1
⇒ y = - x + 3
Therefore, The general form of the equation of the line shown is,
⇒ y = - x + 3

How do you explain a diameter of 0.00085 inches using scientific notation
Answer:
8.5 [tex]E^{-4}[/tex] inches
Step-by-step explanation:
Scientific scientific notation is where the super small / super large number is multiplied by a 10 (E) to the power of a number. Here, the number is smaller than 8.5 so our power must be negative. As we are making it four "places" bigger, we use the exponent of -4.

Can I get some help plz?...
Answer:
[tex]1\frac{1}{2}[/tex]
Step-by-step explanation:
The first step to solving this problem is to convert these into improper fractions.
[tex]7\frac{2}{3} =\frac{21+2}{3}=\frac{23}{3}[/tex]
[tex]5\frac{1}{9} =\frac{45+1}{9}=\frac{46}{9}[/tex]
The second step is to determine the reciprocal of the second term.
Reciprocal of [tex]\frac{46}{9} =\frac{9}{46}[/tex]
The third step is to multiply the first term by the reciprocal of the second term.
[tex]\frac{23}{3}*\frac{9}{46}=\frac{207}{138}[/tex]
The fourth step is to reduce this fraction.
[tex]\frac{207}{138}=\frac{3(69)}{3(46)}=\frac{23(3)}{23(2)}=\frac{3}{2}=1\frac{1}{2}[/tex]
Answer:
1 1/2 or 3/2
Step-by-step explanation:
First you need to make your fractions improper.
7 times 3 + 2 = 23, so the fraction is 23/3
5 times 9 + 1 = 46, so the fraction is 46/9
Since this is division, flip the second fraction.
So instead of 46/9, it's now 9/46
Now you can multiply.
23/3 + 9/46 = 207/138
207/138 simplified is 3/2, or 1 1/2

Answer:
ADE = 63°
Step-by-step explanation:
One thing at a time. We can start telling that triangle ADE is isosceles, of baseAD. Means the two angles EAD e ADE are congruent, and each measures [tex]\frac {180-54}2 = 63°[/tex].
Now look at angles EDA and ECB. They are corresponding angles relative to the parallels DA and CB, so they are congruent. Measure of angle C is the same of measure of angle ADE = 63°
Edit: I've been asked for the rest of the measures. Purple ones are the one you find during the exercize. Red ones are the remaining. External ADC is supplementary to ADC (it's an external angle) angle BAD is alternate to ADE respect to the two parallels AB and CE, so they are congruent. Angle ABC is supplementary to angle BCD since they're internal conjugate relative to the same two parallels.

write an equation in slope-intercept form of the line shown (1,-9) , (-3,-9)
Answer:
y = -9
Step-by-step explanation:
y2 - y1 / x2 - x1
-9 - (-9) / -3 - 1
0 / -4
y = 0 + b
-9 = b
Answer:
[tex]\boxed{\sf{y=-9}}[/tex]Step-by-step explanation:
The slope-intercept form is the only way to solve this problem.
Slope-intercept form:
[tex]\rightarrow \sf{y=mx+b}[/tex]
The m represents the slope.The b represents the y-intercept.Using the slope is another way to solve.
(1,-9) and (-3,-9)Use a slope formula.
Slope:
[tex]\sf{\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{rise}{run} }[/tex]
y2= (-9)
y1= (-9)
x2= (-3)
x1= (1)
Rewrite the problem.
[tex]\sf{\dfrac{(-9)-(-9)}{(-3)-1}=\dfrac{0}{-4}=\boxed{\sf{0} }[/tex]
Therefore, the slope is 0.We're not done yet.
y-intercept= (-9).
The m represents is 0.
The b represents is (-9).
So, the correct answer is y=-9.I hope this helps you! Let me know if my answer is wrong or not.
Use the given root to find the remaining root of the function. Root: x = - 3 Function: f(x) = x ^ 2 + x - 6
Answer:
x = 2
Step-by-step explanation:
Since we know one root is -3, we know one factor of the equation is (x+3)
From there we can use the factor we know to factor the rest of the equation:
x^2 + x - 6 = (x+3) * ?
Since know -6 is just 3 * -2 and since 3-2 is 1,
(x+3)(x-2) = x^2 + x - 6
From there,
x - 2 = 0
x = 2

Graph the line with the equation y = 4/5x + 2
Answer: I have provided a screenshot of what your graph should look like so uh yeah you got this!
The graph of the line with the equation y = 4/5x + 2 is given in below attachment.
To graph the line with the equation y = (4/5)x + 2, we can use the slope-intercept form, which is y = mx + b.
where "m" represents the slope and "b" represents the y-intercept.
In this case, the slope (m) is 4/5, and the y-intercept (b) is 2.
To plot the line, we can start by plotting the y-intercept, which is the point (0, 2).
From there, we can use the slope to find additional points and connect them to form the line.
Let's plot a few more points:
When x = 5:
y = (4/5)(5) + 2
= 4 + 2 = 6
So we have the point (5, 6).
When x = -5:
y = (4/5)(-5) + 2
= -4 + 2
= -2
So we have the point (-5, -2).

Step-by-step explanation.
A system of equations is basically two or more equations that rely on each other. If a solution for a variable is 2, it has to work for the other equation.
The substitution is basically plugging in the y value to y = 8x + 10
If y = 2
and also y = 8x + 10

Side QP is equal to side QR so 4x-2=10, then just solve for x and you get 3
Answer:
x=3

the trangal is isosoles so both sides need to equal 10 so the equation would be 4x-2=10.
frist you would add both sides by 2
4x-2=10
+2 +2
4x=12

Rosa can run 4 miles in 56 minutes. How many kilometers does Rosa run if she runs for 42 minutes?
Answer:
First, let’s use what we know to determine how many miles Rosa can run in a minute.
We do so by dividing 4 by 56 (4/56), which equals .071, after rounding.
So, Rosa runs .071 miles in a minute. Now we multiply this by 42 to get our final answer.
42 x .071 = 2.98. Using rounding, we know that Rosa can run 3 miles in 42 minutes.
