how do you solve the system:
y+1=2x
5y+5=10x
Answer:
choose "infinitely more solutions"
Step-by-step explanation:
Let's solve this system by substitution method
y+1=2x
- 1 = - 1
y = 2x -1 <-- sbstitute this in the next equation
---------------------------------------------------------------------------------
5y+5 = 10x
5(2x -1) + 5 = 10x
10x -5 + 5 = 10x
10x + 0= 10x
- 10x = -10x
0 = 0 <-- infinitely more solutions
Answer:
5+5=10x
y=1×5+5=10x45×+=1+32=
(312) 9 = 3. (9.12)
O A. True
O B. False
Answer:
False
Step-by-step explanation:
Since rounding 312 to the nearest hundred will be 300 and not 3 and rounding 9.12 to the nearest one is 9
and 300≠9

Answer:
Circumference = 37.68
Area = 113.04
Step-by-step explanation:
Circumference = π × d
Circumference = 3,14 × 12 feet
Circumference = 37.68
Area = π × r²
Area = 3,14 × 6 × 6
Area = 113.04

Answer:
437.3 ft
Step-by-step explanation:
The angle of depression can be copied inside the triangle to the angle of elevation (at lower right). Then the side x can be seen to be adjacent to the angle.
The mnemonic SOH CAH TOA reminds you of the relations. Here, we have the hypotenuse and we want the adjacent angle. The relevant relation is ...
Cos = Adjacent/Hypotenuse
cos(29°) = x/(500 ft)
Multiplying by 500 ft gives ...
x = (500 ft)cos(29°)
x ≈ 437.3 ft
_____
Additional comment
You have posted a number of problems that make use of this geometry. They are all solved the same way:
a) identify the desired measure and the given measures
b) using SOH CAH TOA, identify the relation applicable to those measures
c) fill in the given values in the equation
d) solve for the unknown
You may need to make use of what you know about angles and triangles in order to relate given angles to ones you need to use.
A snail moves 3/8 of a foot in 1/5of an hour. What is the snail's speed in feet per hour?
A) 3/40 feet per hour
B) 1 5/8 feet per hour
C) 1 7/8 feet per hour
D) 2 7 /8 feet per hour
Answer:
B) 1 5/8 feet per hour is your answer
3/8foot=1/5hour
15foot =8hour
1 foot =8/15 hour

Answer:
x = 3
Step-by-step explanation:
x = (sq rt 3)( sq rt 3) because the leg opposite the 30 degree angle (sq rt 3) times the set value of sq rt 3 = the leg adjacent to the 30 degree angle.
x = (sq rt 3)(sq rt 3)
x = 3

what is 3/4 as a fraction out of 100, a decimal,and a percentage
Which graph is the solution to the following inequality
Step-by-step explanation:
-8x+5 > 21
Minus 5 from both sides
-8x > 16
Then divide 8 from both sides (also I am pretty sure the sign would change because you are dividing by a negative number)
x < -2
So the answer is x is less than or equal to -2
or C

Answer:
x = 7
Step-by-step explanation:
The corresponding sides are proportional:
(2x +1)/5 = (x +2)/3
3(2x +1) = 5(x +2) . . . . . cross multiply
6x +3 = 5x +10 . . . . . . . eliminate parentheses
x = 7 . . . . . . . . . . . . . . . subtract 5x+3 from both sides

please help me work this out! set up and solve a quadratic equation to work out the value of x
Answer:
x = 8
Step-by-step explanation:
✔️Area of the square = s²
Where,
s = (2x - 4)
Area = (2x - 4)² = (2x - 4)(2x - 4) = 2x(2x - 4) -4(2x - 4)
= 4x² - 8x - 8x + 16
Area of square = 4x² - 16x + 16
Area of rectangle = L × W = (3x - 6) × x
= 3x² - 6x
✔️Since both have the same area, therefore,
4x² - 16x + 16 = 3x² - 6x
Collect like terms
4x² - 3x² - 16x + 6x + 16 = 0
x² - 10x + 16 = 0
Factorize
x² - 2x - 8x + 16 = 0
x(x - 2) -8(x - 2) = 0
(x - 2)(x - 8) = 0
(x - 2) = 0 or (x - 8) = 0
x = 2 or x = 8
If we plug in x = 2 into any of the given side length, we would have 0. (i.e. 2x - 4 = 2*2 - 4 = 0)
So the value of x cannot be 2 because the length of any of the shape cannot be 0.
So therefore, the value of x = 8
