1. What is the solution to the equation 2(x - 10) + 4 = - 6x + 2?
A. -9/2
B. 1
C. 9/4
D. 5/2
Answer:
9/4
Step-by-step explanation:
2(x - 10) + 4 = -6x + 2
2x - 20 + 4 = -6x + 2
2x - 16 = -6x + 2
8x - 16 = 2
8x = 18
x = 18/8 or 9/4
Answer:
the answer is C
Step-by-step explanation:
2(x-10) +4 = -6x + 2
2x-20 +4= -6x +2
2x-16 = -6x+2
+16 = +16
______________
2x = -6x + 18
+6x = +6x +18
_____________
8x =18
x=2.25 or 9/4

Step-by-step explanation:
Given data
Distance= 15km
Time = 2 hours
We know that the expression for the speed is
Speed= distance/time
Substitute
Speed= 15/2
Speed= 7.5 km per hour
Hence the speed is 7.5km/h

A slide at a children's park is 74 inches tall in the horizontal distance The slide covers is 70 inches what is the angle measures created by the slide and the ground
Answer:
46.6°
Step-by-step explanation:
A slide at a children's park is 74 inches tall in the horizontal distance The slide covers is 70 inches what is the angle measures created by the slide and the ground
We solve the above question using Trigonometric function of Cosine.
tan x = Opposite/Adjacent
x = The angle
Hypotenuse = Slide covers = 70 inches
Adjacent = 74 inches
tan x = 74/70
x = arc tan (74/70)
x = 46.591140271°
Approximately = 46.6°

HELPPP!!!!!! THIS IS DUE AT 8:20
Given:
The figure of a right angle triangle.
To find:
The value of x.
Solution:
In a right angle triangle,
[tex]\tan \theta=\dfrac{Opposite}{Adjacent}[/tex]
Using this formula in the given triangle, we get
[tex]\tan (31^\circ)=\dfrac{x}{33}[/tex]
[tex]0.60086=\dfrac{x}{33}[/tex]
[tex]0.60086\times 33=x[/tex]
[tex]19.82838=x[/tex]
[tex]x\approx 19.83[/tex]
Therefore, the value of x is about 19.83 units.
Which graph represents the equation x=2?
Answer:
1)
Step-by-step explanation:
In the line that is the graph of equation x = 2, every ordered pair has 2 as its x-coordinate. That means it's a vertical line that passes through x = 2 on the x-axis.
Answer: 1)
The graph option 1) is the correct answer.
What is an equation?An equation is a mathematical statement that shows that two mathematical expressions are equal.
Given is an equation, x = 2
We see x intercept is 2 and there is no y intercept,
We know when x = a then the line is always parallel to y-axis and here x intercept is 2 therefore the line will pass through 2 on x-axis.
In graph 1) The line is passing through 2 on x-axis and is parallel to y-axis.
Hence, The graph option 1) is the correct answer.

What is the best name for polynomial with 3 terms that has a degree
Answer:
Names of Degrees
Degree Name Example
1 Linear x+3
2 Quadratic x2−x+2
3 Cubic x3−x2+5
4 Quartic 6x4−x3+x−2
Answer:
Quartic Trinomial
Step-by-step explanation:
Monomial = one term
Binomial = two terms
Trinomial = three terms
Polynomial = four or more terms
As the other answer says, the order for degrees is:
Linear - to first degree
Quadratic - to second degree
Cubic - to third degree
Quartic - to fourth degree
Quintic - to fifth degree
Anything above fifth degree is just said "__th degree"
Example: x^7 + x^2 + 5 would be seventh degree trinomial

Copy the shape and fill in the missing angle. Sow the work. Thanks.
Answer:
x=12
Step-by-step explanation:
Hello There!
So first things first, the angle labeled 4x+17 and the blank interior angle are vertical angles meaning that they are congruent
So now we can solve for x
Remember all of the angles in a triangle add up to equal 180 so
180 = x + 23 + 80 + 4x + 17
step 1 combine like terms
4x+x=5x
23+17+80=120
now we have
180=120+5x
step 2 subtract 120 from each side
180-120=60
now we have
60=5x
step 3 divide each side by 5
60/5=12
we're left with x=12
Use the points in each diagram to name the figure shown
60>x and x >57
A x=61
B x=59
C x=50
x is b because 59 is less than 60 but greater than 57.

Find the 3rd term of the sequence. Show me the solutions and calculations.
Given:
[tex]b(1)=-12[/tex]
[tex]b(n)=b(n-1)\cdot 4[/tex]
To find:
The third term of the sequence.
Solution:
We have,
[tex]b(n)=b(n-1)\cdot 4[/tex]
For n=2, we get
[tex]b(2)=b(2-1)\cdot 4[/tex]
[tex]b(2)=b(1)\cdot 4[/tex]
[tex]b(2)=-12\cdot 4[/tex] [tex][\because b(1)=-12][/tex]
[tex]b(2)=-48[/tex]
For n=3, we get
[tex]b(3)=b(3-1)\cdot 4[/tex]
[tex]b(3)=b(2)\cdot 4[/tex]
[tex]b(3)=-48\cdot 4[/tex] [tex][\because b(2)=-48][/tex]
[tex]b(3)=-192[/tex]
Therefore, the 3rd term of the sequence is -192.

Brian is mowing his lawn. He and his family have 7.84 acres. Brian mows 1.29 1 acres on Monday, 0.85 acres on Tuesday, and 3.63 acres on Thursday. How many acres does Brian have left to mow? * 0 2.70 0 20.7 02.07 O 0.207
Answer:
2.07
Step-by-step explanation:
I DID IT ON A CALCULATOR
The area of a 2D form is the amount of space within its perimeter. The area that is needed to be mowed by Brian is 2.07 acres.
What is an area?The area of a 2D form is the amount of space within its perimeter. It is measured in square units such as cm2, m2, and so on. To find the area of a square formula or other quadrilateral, multiply its length by its width.
The total area that is needed to mow is 7.84 acres. Given that Brian mows 1.291 acres on Monday, 0.85 acres on Tuesday, and 3.63 acres on Thursday. Therefore, the area already mowed by Brian can be written as,
[tex]\rm \text{The area already mowed by Brian} = 1.291 + 0.85 + 3.63= 5.771\ acres[/tex]
The area that is left to mow = Total area - Area already mowed by Brian
= 7.84 - 5.771
= 2.069 acres ≈ 2.07 acres
Hence, the area that is needed to be mowed by Brian is 2.07 acres.
