Step-by-step explanation:
(6, 24) this ordered pair has an x-value of 6 and a y-value of 24
The only equation, if you substitute those values into it, which works is D.
24 = 4(6)
24 = 24
What is the first step in simplifying the expression
-5x2(4x3 - x2)2 ?
O Distribute -5x?
Square 4x - x2
Subtract 4x3 - 2
Answer:
Square 4x³ - x²
Step-by-step explanation:
Given the expression -5x²(4x³ - x²)²
The first step in simplifying the expression is to open the parenthesis by taking the square of 4x³ - x² as shown;
-5x²(4x³ - x²)²
= -5x²[(4x³)²- 2x²(4x³) + (x²)²]
= -5x²[16x^6- 8x^5 + x^4]
Hence the correct answer is Square 4x³ - x²

Teri incorrectly solved the system of equations below. Correctly identify the error Teri made. 2x - 10 y = -30 x - 5y = 20 Step 1: x - 5y = 20 x = 5y + 20 Step 2: 2(5y + 20) - 10 y = -30 10y + 40 - 10y = -30 40 = -30
Answer:
See explanations below
Step-by-step explanation:
Given the system of equation
2x - 10 y = -30 ... 1
x - 5y = 20 ... 2
Step: From 2;
x = 20 + 5y ...3
Step 2: Substitute equation 3 into 1
2x - 10y = -30
2(5y+20) - 10y = -30
Open the bracket
10y + 40 - 10y = -30
10y - 10y + 40 = -30
0+40 = -30
40 = -30
The steps taken by Teri are correct all through. He didn't make any error whatsoever

In the diagram, which pair of angles are vertical angles? 12 56 4 3 87 21 and 22 O 24 and 26 O Z6 and 28 O 25 and 23
Answer:
6 and 8
Step-by-step explanation:
vertical lines yes, theyre across from each other making it vertical line
Vertical angles are the angles at the opposite sides of a transversal
The vertical angles are <6 and <8
How to determine the vertical anglesFor a pair of angles to be vertical angles, there must be a transversal line, and the two angles must be at the either sides of the transversal
This means that the following angles are vertical angles
Angles 1 and 3Angles 2 and 4Angles 5 and 7Angles 6 and 8Hence, the vertical angles are <6 and <8

what is the equation of the line in slope intercept form that passes through (-2,5) and (-1,1)
Answer:
y=4/3x+7/3
Step-by-step explanation:
I don't know if this is right.
can i get help on question 2 please
Answer:
last option is the answer
Step-by-step explanation:
the answer cannot be the two middle options because you can see the y-intercept is 2 so the equation must end with that
now you have to determine if the slope of the line is -5 or -1
you can find the slope by selecting two points on the line; for example, (0,2) and (1,1) and using formula: difference of y-values 2 - 1
difference of x-values 0 - 1
the slope is -1
is the expression 3 (x + 1 1/2) - 3 equivalent to 3x + 1 1/2?
Answer:
Yes
Step-by-step explanation:
If you multiply the 3 into the equation it will give you 3x+3 3/2 -3 and if you simplify it the answer is 3x+4 1/2 -3=3x +1 1/2.
3x+1 1/2 = 3x + 1 1/2
a rectangle has a width that is 1/2 its length the perimeter of this rectangle is 42 inches what is the width of the rectangle...what is the width of the rectangle
Answer:
w = 7 inches
Step-by-step explanation:
length = n
width = n/2
Perimeter = 2n + 2(n/2)
42 = 2n + n
42 = 3n
n = 14
width = 14/2 = 7

Step-by-step explanation:
Opposite sides and angles of a parallelogram are equal.
So,
3x - 1 = 35
Add 1 to both sides
3x = 35 + 1
3x = 36
Divide 3 to both sides
x = 36 / 3
x = 12

Sketch a graph of the polynomial function f(x) =x3− 2x2. Use it to complete the following:
f is------ on the intervals (−∞, 0) and (0, 2).
f is------ on the interval (2,∞).f is on the interval (0, 4__3).
f is------ on the intervals (−∞, 0) and(4__3, ∞).
Answer:
We have the function:
f(x) = x^3 - 2*x^2
To sketch this, we need to graph some points, and then just draw a line that passes through the points.
The graph of this equation is shown below.
Now we can complete the question.
If the graph is below the x-axis in some interval, the function is negative in that interval
If the graph is above the x-axis in some interval, the function is positive in that interval.
If the graph goes up in a interval, then the function is increasing in that interval
If the graph goes down on an interval, then the function is decreasing in that interval.
Then:
1) f is------ on the intervals (−∞, 0) and (0, 2).
Here we can see that the graph is below the x-axis in those intervals, then here we have:
f is negative on the intervals (−∞, 0) and (0, 2).
2) f is------ on the interval (2,∞)
Here the answer is positive:
f is positive on the interval (2,∞)
3) fi is ------ on the interval (0, 4/3)
In the graph, you can see that the graph goes down in that interval, then the correct answer here is:
f is decreasing on the interval (0, 4/3)
4) f is------ on the intervals (−∞, 0) and (4/3, ∞).
In this case, we can see that the graph goes up in these intervals, then the correct answer here is:
f is increasing on the intervals (−∞, 0) and (4/3, ∞).

5 1/8 - 2 3/4
Answer:2 3/ 8
Step-by-step explanation: 5 1/8 - 2 3/4
= 41/ 8 - 11/4
= 41/8 - 22/8
=19/8
=2 3/ 8
Change to improper fraction .Then make the denominator the same ,make both denominator to 8 . Now you have 41/8 and 22/8 ,you can subtract it and it gives you 19/8.Lastly you make the improper fraction to mixed numbers which is 2 3/ 8 .
Write the fractions from parts (a) and (b) as a proportion, and solve to find out how many miles Alex's friend's house is from school. Round your answer to the tenths place. *
Question:
Alex skateboards at a constant speed from his house to school 3.8 miles away. It takes him 18 minutes.
a. What fraction represents his constant speed, c?
b. After school, Alex skateboards at the same constant speed to his friend’s house. It takes him 10 minutes. Write the fraction that represents constant speed, c, if he travels a distance of y.
c. Write the fractions from parts(a) and (b) as a proportion, and solve to find out how many miles Alex’s friend’s house is from school. Round your answer to the tenths place.
Answer:
(a) [tex]c = \frac{3.8}{18}[/tex]
(b) [tex]c = \frac{y}{10}[/tex]
(c) 2.1 miles
Step-by-step explanation:
Solving (a):
Given
[tex]Distance = 3.8\ miles[/tex]
[tex]Time = 18\ minutes[/tex]
Required
Determine the constant speed, c.
Speed is calculated as:
[tex]Speed = \frac{Distance}{Time}[/tex]
So, we have:
[tex]c = \frac{3.8}{18}[/tex]
Solving (b):
Given
[tex]Distance = y[/tex]
[tex]Time = 10\ minutes[/tex]
Required
Determine the constant speed, c.
Speed is calculated as:
[tex]Speed = \frac{Distance}{Time}[/tex]
So, we have:
[tex]c = \frac{y}{10}[/tex]
Solving (c): Write (a) and (b) as proportions and solve for y.
As a proportion, we have
[tex]\frac{y}{10} = \frac{3.8}{18}[/tex]
Multiply both sides by 10
[tex]10 * \frac{y}{10} = 10 * \frac{3.8}{18}[/tex]
[tex]y = 10 * \frac{3.8}{18}[/tex]
[tex]y = \frac{38}{18}[/tex]
[tex]y = 2.11111[/tex]
[tex]y = 2.1\ miles[/tex] ---- approximated
A bottle of 150 vitamins costs $5.25. If the cost varies directly with the number of vitamins in the bottle, what should a bottle of 250 vitamins cost?
Answer:
$8.75
Step-by-step explanation:
Set up a proportion where x is the cost of a bottle with 250 vitamins:
[tex]\frac{150}{5.25}[/tex] = [tex]\frac{250}{x}[/tex]
Cross multiply and solve for x
150x = 1312.5
x = 8.75
So, it will cost $8.75 for a bottle with 250 vitamins

Ok I need help solving this...
A. 105
B. 120
C. 50
D. 125
Answer:
A - 105
Step-by-step explanation:
since the two measurements are supplements, you do x+82+x+112=180. then you get x=-7. then you do 112-7=105
Answer:
105°
Step-by-step explanation:
A line equals 180, so take the two expressions and set them equal to 180:
x+82+x+112=180
simplify:
2x+194=180
2x=-14
x=-7
now plug the x value into the bolded expression
x+112
-7+112 = 105°
2x + 6 = 6x - 22

P Р
The length of TU is
Answer:
TU = 8.4
Step-by-step explanation:
The geometric figure consists of the following segments;
1) 4 parallel lines, WS, YR, XQ, and, VP
2) Three transversals, VW, PS, and, TU
The given parameters are;
PQ = QR = RS
Therefore, given that the transversal, PS, makes equal intercept with the 4 given parallel lines, by equal intercept theorem, the transversal TU will make equal intercepts with the given parallel lines
Therefore;
TX = 2.8 = XZ = ZU
From which we have, by segment addition postulate;
TU = TX + XZ + ZU
∴ TU = 2.8 + 2.8 + 2.8 = 8.4
TU = 8.4.
