early says that m ×(-1) is always equal to m ÷(-1) for all rational values of m. is he correct
Answer:
The equation are true.
Step-by-step explanation:
Given
[tex]m * (-1) = m / (-1)[/tex]
Required
True or false?
We solve this question from right to left:
[tex]m * (-1) = m / (-1)[/tex]
Express / as *
[tex]m * (-1) = m * 1/(-1)[/tex]
[tex]m * (-1) = m * (-1)[/tex]
The expression on both sides of the equation are true.

Answer:
-3,2 -2,4 1,-1
Step-by-step explanation:
Suppose y varies directly as x. If x = 24 when y = 8, then what is the constant of variation
Direct variation is represented by the formula [tex]\frac{y}{x} = k[/tex]
where k is the constant of variation.
So here, since we know that x = 24 and y = 8,
the constant of variation must be equal to 8/24.
if we write 8/24 in lowest terms, we have 1/3.
So 1/3 = k.
0.2 =% yssssssssssssssssssssssssssssssssssssssssss
Answer:
20%
Step-by-step explanation:
If it was 0.3 it would be 30% or if it was .35 it would be 35%.
0.3 is another way of writing 0.30 but since it's just a zero, you don't really have to write 30.

Eva is going to the amusement park, where she has to pay a set price of admission and another price for tickets to go on each of the rides. The total amount of money Eva will spend is given by the equation y=26+1.5x. , where y represents the total amount of money, in dollars and cents, and represents the number of rides Eva goes on . What could the number 1.5 represent in the equation ?
Answer:
B. The change in the total amount if money for every one additional ride she goes on
Step-by-step explanation:
Given,
y = 26 + 1.5x, where,
y = total amount of money Eva will spend
x = number of rides Eva rides on
Thus,
Set price of admission into the amusement park = $26
Price per ride = $1.5
Therefore, the 1.5 I'm the equation can be said to be "the change in the total amount if money for every one additional ride she goes on".
In the diagram below of parallelogram ROCK, m angle is 70 degrees and m angle ROS is 65 what is the value of x
Answer:
135
Step-by-step explanation:
The measure of the angle KSO is 135°
What is a parallelogram?A parallelogram is a special type of quadrilateral that has both pairs of opposite sides parallel and equal.
Given that, In the diagram below of parallelogram ROCK, m angle is 70 degrees and m angle ROS is 65
We know that, opposite angles of a parallelogram are equal,
Therefore, ∠ ORK = 70°
In triangle, SRO, ∠ ORK and ∠ ROS are interior angles, and ∠ KSO is an exterior angle,
We know, The measure of an exterior angle of a triangle is equal to the sum of the measures of the two non-adjacent interior angles.
Therefore, ∠ KSO = ∠ ORK + ∠ ROS
∠ KSO = 135°
Hence, The measure of the angle KSO is 135°

Answer:
∠D = 52º
∠E = 32º
∠F = 96º
Step-by-step explanation:
the sum of interior angles of a triangle equals 180º
so: (x + 20) + (3x) + 32 = 180
3x + x + 20 + 32 = 180 combine like terms
4x + 52 = 180 subtract 52 from both sides
4x = 128 divide both sides by 4
x = 32
plug x into each angle measure to get them:
∠D = (32) + 20 = 52º
∠E = 32º (given)
∠F = 3(32) = 96º

Newton's law of cooling states that the temperature of an object changes at a rate proportional to the difference between its temperature and that of its surroundings. Suppose that the temperature of a cup of coffee obeys Newton's law of cooling. If the coffee has a temperature of 185 degrees Fahrenheit when freshly poured, and 3 minutes later has cooled to 167 degrees in a room at 60 degrees, determine when the coffee reaches a temperature of 137 degrees.
Answer:
9.4 secs
Step-by-step explanation:
From Newton's law of cooling;
T(t) = Ts + Do e^-kt
Where;
D0= initial temperature difference
Ts= Temperature of the surroundings
t= time
K = positive constant
Do = 185 - 60 = 125 degrees
167 = 60 + 125 e^-3k
167 - 60 = 125 e^-3k
107/125 = e^-3k
ln(e^-3k) = ln(107/125)
-3k = -0.1555
k = 0.1555/3
k = 0.0518
Substituting the value of k to find the time taken to reach 137 degrees
T(t) = Ts + Do e^-kt
137 = 60 + 125 e^-(0.0518t)
137 - 60 = 125 e^-(0.0518t)
77 = 125 e^-(0.0518t)
e^-(0.0518t)= 77/125
ln [e^-(0.0518t)] = ln(77/125)
-0.0518t = -0.4845
t = 0.4845/0.0518
t = 9.4 secs

Find the equation of the exponential function represented by the table below:
Answer:
[tex]f(x)=5(4)^x[/tex]
Step-by-step explanation:
The exponential function is [tex]f(x)=ab^x[/tex]. [tex]a[/tex] is the initial value of the function, or the y-value when x=0. In this case, [tex]a[/tex]=5. If we enter that into the equation:
[tex]f(x)=5b^x[/tex]
Then we can use another point to solve for [tex]b[/tex].
[tex]20=5b^1[/tex]
Since anything raised to the power of 1 remains the same, we can continue to solve algebraically.
[tex]20=5b\\\frac{20}{5}=\frac{5b}{5}\\b=4[/tex]
Now that we have both the [tex]a[/tex] and [tex]b[/tex] value, we can return to the exponential function and fill in the blanks.
[tex]f(x)=5(4)^x[/tex]
