Suppose that Kevin's checking account shows a balance of $910.25 at the beginning of the month. During this month, he makes deposits of $175.35, $472.25, $235.40, and $450.15, and he writes checks for $307.50, $289.25, $150.30, and $327.00. Find the end-of-the-month balance in his account.
Answer:
The answer is $1,169.35
Step-by-step explanation:
Deposits is when you put money into your account, so, you'll add what he deposits. which will be $2,242.4, Next when he writes a check it means he took money out of his account so you'll subtract. You'll add up the amount of checks he wrote and subtract your answer with the deposits so, $2,243.4, - $1,074.05 = 1,169.35 and thats how you get your answer.
A particle moves along the x-axis so that at time t\ge 0t≥0 its velocity is given by v(t)=3t^2-18t+15.v(t)=3t2−18t+15. Determine all values of tt when the particle is at rest.
When a particle is at rest, the velocity = 0. Therefore, we equate the v(t) term to zero (0)

Can you help me find the slope, y-intercept, and the equation based off this chart?
y-interceptis As given by the question
There are given that the value of x and y.
Now,
For finding the value of the slope, choose two-point from the given table
So,
Suppose the two points are:
[tex](1,\text{ 5) and (}3,\text{ 3)}[/tex]Now,
From the formula of slope:
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]Where,
[tex]x_1=1,y_1=5,x_2=3,y_2=3[/tex]Put all the above value into the given formula
So,
[tex]\begin{gathered} m=\frac{y_2-y_1}{x_2-x_1} \\ m=\frac{3_{}-5_{}}{3_{}-1_{}} \\ m=-\frac{2}{2} \\ m=-1 \end{gathered}[/tex]Hence, the value of the slope is -1.
Now,
For the equation of the line that is based on the given chart, use two supposes point and the given slope.
So,
The two poin and slope is:
[tex](1,\text{ 5) and (3, 3) and m=-1}[/tex]Then,
From the formula of two point form;
[tex](y-y_1)=m(x-x_1)[/tex]Where,
[tex]x_1=1,y_1=5,x_2=3,y_2=3,\text{ m=-1}[/tex]Then,
Put all the given value into the above formula
So,
[tex]\begin{gathered} (y-y_1)=m(x-x_1) \\ (y-5_{})=-1(x-1_{}) \\ (y-5)=-x+1 \\ y-5+x-1=0 \\ y+x-6=0 \end{gathered}[/tex]Hence, the equation of the line is:
[tex]y=-x+6[/tex]Now,
To find the y-intercept, put x=0 and solve for x
So,
The y intercept of the given equation is:
[tex]\begin{gathered} y=-x+6 \\ y=-(0)+6 \\ y=6 \end{gathered}[/tex]Hence, the y-intercept is (0, 6)

The value of x from the equation represented by the given bar diagram is 20.
The equation is represented using the bar diagram and from the bar diagram be can observe that the equation will be the following equation mentioned below:
3.5 x + 12.5 x = 320 equation 1
The bar diagram represents 3.5 x + 12.5 x = 320 equation. Now we will simplify this equation and will find the value of x from this equation. The steps that need to be followed to simplify this equation are shown below;
3.5 x + 12.5 x = 320
16 x = 320
Divide both sides of equation by 16 , we will get
x = 320/16
x = 20
The value of x from the equation 3.5 x + 12.5 x = 320 is 20.

y equals negative two thirds times x minus 3
y equals negative three halves times x minus 2
y equals negative three halves times x minus 3
y equals negative two thirds times x minus 2
y equals negative two thirds times x minus 2 is the equation of graph.
What is slope of line?The slope of the line is the ratio of the rise to the run, or rise divided by the run.
The given two points are 3 comma 0 and 0 comma negative 2.
i.e (3,0)(0,-2)1)
The formula for slope is (y₂-y₁)/(x₂-x₁)
slope = (-2 - 0) / (0 - 3)
= -2 / -3
The negative negative are multiplied we get positive
= 2/3
The standard form of a line is y = mx + b, where m is slope of line and b is y intercept.
slope(m) = 2/3
We can use either of points (0,-2)...x = 0 and y = -2
now sub and find b, then y intercept
-2 = 2/3(0) + b
-2 = b
so equation is : y = 2/3x - 2
Hence y equals negative two thirds times x minus 2 is the equation of graph.

The angles in the parallelogram is as follows:
a = 27°b = 55°c = 55°How to find angles in a parallelogram?A parallelogram is a quadrilateral with opposite sides equal to each other and opposite side parallel to each other.
The diagonal of a parallelogram bisect each other.
Therefore, the angles a, b and c in the parallelogram can be found as follows:
180 - 118 - 35 = a (sum of angles in a triangle)
180 - 153 = a
a = 27 degrees.
Therefore, let's find angle b.
62 + 63 + b = 180 (sum of angles in a triangle)
125 + b = 180
180 - 125 = b
b = 55 degrees
Let's find the angle c
Hence,
b = c (alternate angles)
Therefore,
c = 55 degrees.

Select the correct answer. Jonathan has 30 chocolates. He gives some chocolates to his friend David. He then gives Sarah half the number of chocolates that he gave David and gives Lily two-thirds of what he gave David. After giving away the chocolates, Jonathan has 4 chocolates left. If the number of chocolates Jonathan gives David is x, which equation represents the situation? How many solutions does this equation have? A. x + 1 2 x + 2 3 x = 30 − 4 , which has no solution B. x + 1 2 x + 2 3 x = 30 , which has infinitely many solutions C. x + 1 3 x + 2 3 x − 4 = 30 , which has one solution D. x + 1 2 x + 2 3 x + 4 = 30 , which has one solution E. 1 2 x + 2 3 x = x − 4 , which has no solution
The solution to equation x+ 1/2x+2/3x+4= 30 and has one solution x = 12 which is the correct answer would be an option (D).
The no. of chocolates given to Sarah = 1/2 of x = x/2
Then Lily has two-thirds of what he has given David. Following the distribution of the chocolates,
The number of chocolates provided to Lily is equal to two-thirds of the number of chocolates given to David.
The number of chocolates given to Lily Equals 2/3 of x = 2x/3
Now, the total number of chocolates delivered to David, Sarah, and Lily
= x+x/2+2x/3
Here LCM of 2 and 3 is 6
The Total no. of chocolates given to David, Sarah, and lily
= (6x + 3x+ 4x)/6
The total number of chocolates distributed to David, Sarah, and Lily is 13x/6.
Jonathan had four chocolates left after giving them out.
The number of chocolates left with Jonathan equals the total number of chocolates given to David, Sarah, and Lily.
⇒ 4 = 30 - 13x/6
⇒ 4 + 13x/6 = 30
⇒ 13x/6 = 30-4 = 26
⇒ x = 26×6/13 = 2×6
⇒ x = 12
Hence, the equation which represents the given situation is 30 - 13x/6 =4

let the consecutive odd integers be
x, x+ 1, x+ 2, x + 3, x + 4
Average = sum / total number

Total number = 5
-45 = x + x + 1 + x + 2 + x + 3 + x + 4 / 5
Introduce cross multiplication

[tex]\begin{gathered} \angle BAD\cong\angle ABC \\ \angle ADC\cong\angle BCD \end{gathered}[/tex]The angles are congruent because if AD and BC are congruent, and the lines are parallel, they sides will form the same angles.
Also, as the segment AD is "cut" by two parallel lines, the angles BAD and ADC are consecutive interior angles and are, therefore, supplementary.
Then, we can write:
