If TRAP is an isosceles trapezoid, what is the value of x?
(5x +9)"
R
A. 9
B. 25
C. 18
D. 23
E. 19
F. Cannot be determined
Answer: 19, I had to get the question wrong :/
The value of x is 19
How to determine the value of x?From the question we understand that TRAP is an isosceles trapezoid
This means that the adjacent angles add up to 180 degrees.
So, we have:
5x + 9 + 4x = 180
Evaluate the like terms
9x = 171
Divide both sides by 9
x = 19
Hence, the value of x is 19

what is g(3)=
?????
Answer:
g(3) = 4
Step-by-step explanation:
The question means what is the value of y when x = 3
Locate x = 3 on the x- axis. Go vertically up until the dot is met and read off the corresponding value on the y- axis, that is y = 4
Thus when x = 3 then y = 4, or
g(3) = 4
The value of g(3) from the graph given is 4
The given diagram is a graph in the xy-plane with different coordinate points.
g(x) is the output value of the function for an input value of x.Th order to get g(3), this means that we need to get the corresponding y-value for the value of x.The point that has an x-coordinate of 3 is the point o the coordinate (3, 4). Hence the required value of y when x = 3 is 4.Hence we can conclude that the value of g(3) is 4

Mr. Morales purchases 6 boxes of pencils, 12 boxes of pens, and 4 cases of notebook paper for his classroom. Each box of pencils costs $4.10, each box of pens costs $6.50, and each case of notebook paper costs $105. What is the total cost in dollars of his classroom supplies?
Answer:
$522.60
Step-by-step explanation:
pencils: $4.10 * 6 ===> $24.60
pens: $6.50 * 12 ===> $78
notebook paper: $105 * 4 ===> $420
pencils + pens + notebook paper = total cost

Hi! Would you guys mind anderring this? A submarine is at a depth of 100 feet below sea level. Then it starts to dive at a rate of 50 feet per minute. What is the slope?
Answer:
slope (m) = -50 or -50x
Step-by-step Explanation
I'm assuming that the x-axis is divided by 1 minute segments.
The slope is defined as "the change in y-coordinate" divided by "the change in x-coordinate"
Since the y value is decreasing (negative) 50 feet per minute, then it is safe to say that the slope is -50 (feet)/ 1 minute
Therefore... the slope is -50 or -50x depending on the answer the assignment is looking for
Answer:
Independent variable: Time in minutes
Dependent variable: The elevation in feet
Slope: -50
Y-Intercept: -100

The angle measurements in the diagram are represented
by the following expressions.
ZA= 63 - 189
ZB = 142 + 38°
Solve for x and then find the measure of ZA:
Answer:
∠A = 30°Step-by-step explanation:
∠A + ∠B = 180
where ∠A = 6x - 18
∠B = 14x + 38
first step is to solve for x:
6x - 18 + 14x + 38 = 180
6x + 14x = 180 + 18 - 38
20x = 160
x = 160 / 20
x = 8
now substitute x=8 into angle A
∠A = 6x - 18
∠A = 6(8) - 18
∠A = 30°
In a three-digit number, the tens digit is the same as the hundreds digit. The ones digit of this number is equal to 1/3 of the sum of the other two digits. Find the number if the sum of all its digits is equal to 24.
Answer:
The three digit number is;
996
Step-by-step explanation:
The three digit can be written xyz
ones digit is equal to 1/3 the sum of the two other digits
z = 1/3(x + y)
x + y + z = 24
Tens digit is same as hundreds digit
That means x = y
z = 1/3 (x + x) = 2x/3
So;
2x/3 + x + x = 24
Multiply through by 3
2x + 3(2x) = 72
8x = 72
x = 72/8
x = 9
x = y = 9
z = 1/3(18)
z = 6

Answer:

Step-by-step explanation:
Answer:
2. m = 1
3. y - (-1) = 5 (x - 4)
4. y = 5x - 21
Step-by-step explanation:
Work for #2
m (slope) = [tex]\frac{y2 - y1}{x2 - x1} \fracyx}[/tex]
m = [tex]\frac{-1 - 2}{-2 -1}[/tex]
m = [tex]\frac{-3}{-3}[/tex]
m = 1
Work for #3
y = -1/5x + 3 and through (4, -1)
The slope of a perperndicular line is the negative reciprocal. So, it is 5.
Plug this number into point-slope form. Use the points you were given (4,-1) in the equation as well.
y - y1 = m (x - x1)
y - (-1) = 5 (x - 4)
y + 1 = 5x - 20 (Only if you are supposed to simplify it)
Work for #4
Finish solving the equation
y - (-1) = 5 (x - 4)
y + 1 = 5x - 20
y = 5x - 20 - 1
y = 5x - 21

If f(x) = -3, then x = _____ .
Answer:
x = -5
Step-by-step explanation:
f(x) is the same thing as y. so when y=-3, find that point and the x is -5
The answer to the given problem can be stated as, "If f(x) = -3, then x = -5.
What is a function?A function y = f(x) is defined as a one to one relation between sets X and Y. The set X is called the domain while Y is called the range of f(x).In order to find the different values of f(x) for different x on a graph, draw perpendicular lines to both the axis.
The graph given in the problem shows different points lying on it.
In order to find the value of x at f(x) = -3, draw a perpendicular line from the graph at which the value of f(x) is -3.
The x coordinate obtained is given as x = -5.
Hence, the required value of x at f(x) = -3 is -5.

Abby counts 12 large boxes and 18 small boxes of pencils in the supply cabinet. Each large box contains 144 pencils . Each small box contains 24 boxes. Estimate the total number of of pencils. Explain why it might be better to have an underestimate rather than an overestimate.
Answer:
2,160 pencils
Step-by-step explanation:
Large boxes = 12
Small boxes = 18
Each large box contains 144 pencils . Each small box contains 24 pencils
Total pencil in large boxes = Total large boxes × number of pencils per box
= 12 × 144
= 1,728 pencils
Total pencil in small boxes = Total small boxes × number of pencils per box
= 18 × 24
= 432 pencils
Estimate the total number of of pencils
Total number of pencils = total pencils in large boxes + total pencil in small boxes
= 1,728 pencils + 432 pencils
= 2,160 pencils
It is better to have an underestimate than an overestimate so that you won't disappoint your buyers when they request for a quantity of supply. If it is underestimated; you can meet demand, if it is overestimated; you can't meet demand
