Work out the value of x
Answer:
Step-by-step explanation:
Add 87° + 63° = 150°
then set up this equation:
x + 150° = 180°
x + 150° = 180°
- 150° = -150°
x = 30°
When you add 87 + 63 + 30
it should give you 180° if it doesnt equal 180° then recheck your work.

Vector V is shown in the graph below.
HELP!
Which of the following represents the linear form of v?
v= -6i -8j
v= -8i-6j
v= 6i +8j
v= 8i +6j
Answer:
v = -8i - 6j
Step-by-step explanation:
The starting point is (9, 9)
The direction of the vector is the direction of the arrowhead.
The i is the horizontal component.
The j is the vertical component.
Therefore, to go from the start to the end of the line, we need to travel negative 8 units (horizontally) and negative 6 units (vertically).
Therefore, v = -8i - 6j
Answer:
(b) v = -8i -6j
Step-by-step explanation:
The unit vectors in the x- and y-directions are i and j, respectively.
The vector v shown in the graph extends from x=9 to x=1, or (1 -9) = -8 units in the x-direction.
It extends from y=9 to y=3, or (3-9) = -6 units in the y-direction.
Represented as a sum of x- and y-vectors, that is ...
v = -8i -6j

Add 5 points of 100% and divide by 6 (total entries)92 + 5(100) / 6592/698.67%Solution
Five 100s will bring up the 92% up by 6.67% to 98.67%The work of a student to solve the equation 3(3x − 4) = 8 + 2x + 5 is shown below: Step 1. 3(3x − 4) = 8 + 2x + 5 Step 2. 6x − 7 = 13 + 2x Step 3. 6x − 2x = 13 + 7 Step 4. 4x = 20 Step 5. x = 5 In which step did the student first make an error and what is the correct step? (1 point) Step 2, 9x − 12 = 13 + 2x Step 2, 9x − 4 = 2(6 + x + 3) Step 3, 6x + 2x = 13 + 7 Step 3, 6x − 2x = 13 − 7
Answer:
(a) Step 2. 9x -12 = 13 +2x
Step-by-step explanation:
The distributive property says a factor outside parentheses multiplies each term inside parentheses. It is an error to do addition of the factor, or to miss multiplying a term.
In Step 2 of this "solution", the factor of 3 is erroneously added to each coefficent inside parentheses. It should be multiplied.
Correct Step 2: 9x -12 = 13 +2x
__
The rest of the solution should be ...
Step 3: 9x -2x = 13 +12
Step 4: 7x = 25
Step 5: x = 25/7
___
Check
3(3(25/7) -4) = 8 + 2(25/7) +5

Find the rate of change for f(x)=x^2-8x+15 from x=0 to x=4
Answer:
-4
Step-by-step explanation:
Find the rate of change for f(x) = x² - 8x + 15 from x = 0 to x = 4
The rate of change is the rate at which a variable changes over a specific period of time.
Averate rate of change: [tex]\frac{f(b)-f(a)}{b-a}[/tex]
First, we need to find the functions for when x = 0 and when x = 4:
For x = 0
f(x) = x² - 8x + 15
f(0) = 0² - 8(0) + 15
f(0) = 0 - 0 + 15
f(0) = 15
For x = 4
f(x) = x² - 8x + 15
f(4) = (4)² - 8(4) + 15
f(4) = 16 - 32 + 15
f(4) = -16 + 15
f(4) = -1
Averate rate of change: [tex]\frac{f(b)-f(a)}{b-a}[/tex]
A = [tex]\frac{f(4)-f(0)}{4-0}[/tex]
A = [tex]\frac{-1-15}{4-0}[/tex]
A = [tex]\frac{-16}{4}[/tex]
A = [tex]-4[/tex]
Therefore, the rate of change from x = 0 to x = 4 is -4.

Find the volume of the cylinder.
Either enter an exact answer in terms of \piπpi or use 3.143.143, point, 14 for \piπpi.
Volume is the measure of 3 dimensional space. The volume of the considered cylinder whose radius is of 3 units, and height of 6 units is V = 54π cubic units.
What is the volume of a cylinder?Suppose that the radius of considered cylinder be 'r' units.
And let its height be 'h' units.
Then, its volume is given as:
[tex]V = \pi r^2 h \: \rm unit^3[/tex]
For this case, we're specified that:
Radius of the considered cylinder = r = 3 unitsThe height of the considered cylinder = h= 6 units.Thus, the volume of this cylinder is:
[tex]V = \pi r^2 h = \pi (3)^2 (6) = 54\pi\: \rm unit^3[/tex]
Thus, the volume of the considered cylinder whose radius is of 3 units, and height of 6 units is V = 54π cubic units.

Daddy spends 50% of his salary on rent, 1/4 of the remainder on groceries and keeps the rest. If he keeps $4800, how much is his salary
Answer:
$19,200
Step-by-step explanation:
Daddy spent 3/4 of his salary on things.
This means that you can multiply 4,800*4 to find the salary as 4,800 is 1/4 of the total salary.
4,800*4=19,200

The dimensions of a rectangle are shown. What is the perimeter, in units of the rectangle?
Answer:
the perimeter, in units of the rectangle is 16x + 20
Step-by-step explanation:
perimeter of a rectangle be is 2(L + B)
p = 2(L + B)
L = 5x + 2
B = 3x + 8
p = 2L + 2B
p = 2(5x + 2) + 2(3x + 8)
p = (10x + 4) + (6x + 16)
p = 10x + 4 + 6x + 16
Collect like terms
p = 10x + 6x + 4 + 16
p = 16x + 20
Answer: 16x+20
Step-by-step explanation:
perimeter of a rectangle is the length of all sides added together.
(3x+8)+(3x+8)+(5x+2) + (5x+2)
combine like terms

What is an equation of the circle with center (-5,4) and a radius of 7?
(1) (x - 5)² + (y + 4)² = 14
(2) (x - 5)2 + (y + 4)² = 49
(3) (x + 5)² + (y — 4)² = 14
(4) (x + 5)² + (y - 4)² = 49
Answer:
Option D
Step-by-step explanation:
Given:
Center point: (-5, 4)Radius: 7Formula:
Equation of circle: (x - h)² + (y - k)² = r²
[Where (h, k) is the center point and "r" is the radius of the circle]
Substitute the coordinates of the center point in the formula:
Given center point: (-5, 4)
∴ x-coordinate of center point (h) = -5; y-coordinate of center point (k) = 4
⇒ (x - h)² + (y - k)² = r²⇒ [x - (-5)]² + [y - 4]² = r²Substitute the radius in the formula:
Given radius: 7
⇒ [x - (-5)]² + [y - 4]² = r²⇒ [x - (-5)]² + [y - 4]² = (7)²Simplify both sides of the equation:
⇒ [x + 5]² + [y - 4]² = (7)(7)⇒ [x + 5]² + [y - 4]² = 49 (Option D)Therefore, Option 4 is correct.
Which expression is equivalent to -3x+9?
A.-3(x+9)
B.-3(x-3)
C.-3(x+12)
D.3(-x-3)
Explanation:
Use the distributive property to pull out the -3
When going in reverse like this, we divide each term by -3
-3x/(-3) = x
9/(-3) = -3
So -3x+9 = -3(x-3)
We can verify this by multiplying the -3 outside with each term inside
-3 times x = -3x
-3 times -3 = 9
This shows how -3(x-3) turns into -3x+9 again.
