Answer:
6
Step-by-step explanation:
5x + 2 - 7x = -10
Combine the two x's:
-2x + 2 = -10
Subtract 2 from both sides:
-2x = -12
Divide both sides by -2:
x = 6
If f(x) = 3^x and g(x) = 2x + 5, at which value of x is f(x) < g(x)?
A. -1
B. 2
C. -3
D. -4
Answer:
A) x = -1
Step-by-step explanation:
[tex]f(-1)=3^{-1}=\dfrac13\\\\g(-1)=2(-1)+5=3\\\\\implies f(x) < g(x)[/tex]
[tex]f(2)=3^{2}=9\\\\g(2)=2(2)+5=9\\\\\implies f(x)=g(x)[/tex]
[tex]f(-3)=3^{-3}=\dfrac{1}{27}\\\\g(-3)=2(-3)+5=-1\\\\\implies f(x) > g(x)[/tex]
[tex]f(-4)=3^{-4}=\dfrac{1}{81}\\\\g(-4)=2(-4)+5=-3\\\\\implies f(x) > g(x)[/tex]
you had $22 to spend on three pretzels. After buying them you had $15.70.How much did each pretzel cost?
Answer: $2.10
Step-by-step explanation: 22-15.70= 6.3
This means you spent $6.30 on pretzels. Divide 6.30 by 3 to find out how much each pretzel costs. You would get 2.1 (which is written as $2.10 in money).

So far, Ricardo has scores of 13, 17, 19 and 21 points for the first four rounds of a dice game. What does he need the total score to be for the next two rounds combined in order to achieve an average score of 20 points per round for all six rounds?
Answer:
40 points
Step-by-step explanation:
The score for the first four rounds of the game is 13, 17, 19, and 21 points.
Let [tex]S_5[/tex] and [tex]S_6[/tex] be the scores of the fifth and sixth games respectively in order to achieve an average score of 20 points per round for all six rounds.
[tex]\text{Average score} = \frac{\text{Sum of the scores of all the rounds}}{\text{Total number of the rounds}}[/tex]
[tex]\Rightarrow 20=\frac{13+17+19+21+S_5+S_6}{6}[/tex]
[tex]\Rightarrow 20\times6=80+S_5+S_6[/tex]
[tex]\Rightarrow S_5+S_6=120-80=40.[/tex]
Hence, the combined score of the fifth and sixth rounds are 40 points.

A pilot was scheduled to depart at 4:00 pm, but due to air traffic, her departure has been delayed by 10 minutes. Air traffic control approved a new flight plan that will allow her to arrive three times faster than she calculated in her original flight plan. Let x represent the time, in minutes, of her original flight. Create an equation that can be used to predict the number of minutes after 4:00 pm she will arrive at her destination. y equals one third times x plus 10 y = 3x + 10 y equals one third times x minus 10 y = 3x − 10
Answer:
a. y equals one third times x plus 10
= y = 1/3(x) + 10
Step-by-step explanation:
Let us represent:
Let the original final plan = x
Let the current flight plan = y
The initial time of departure = 4.00pm
Her flight was then delayed for 10 minutes
We are told in the question that:
The current flight plan allows her arrive at her destination three times faster.
This means y= (1/3)x
y = x/3
Hence the equation generated =
y = x/3 +10
y = 1/3(x) + 10
Answer:
y = 1/3x + 10

In the given figure, O is Center of circle. If AC//DB and angle ABC=50 , find angle ACD
Answer:
Step-by-step explanation:
m∠ACB = m∠CBD = 90° ⇒ m∠CAB = 90° - 50° = 40° = m∠ABD ( Alternate interior angles )
m∠CBD = 90°
m∠CDB = 50 °
Check the picture below, notice the tickmarks, both sides are equal and they make twin angles on the "base" side of the isosceles triangle.

We know that 1/2 = 0.5, then (-1/2) = -0.5
So we conclude that
-0.5 and (-1/2) are equivalent.
Another equivalent pair is:
11/20 and 0.55
To check this, you can just solve the fraction in your calculator, you will see that:
11/20 = 0.55
Then 11/20 and 0.55 are equivalent.
The final equivalent pair is:
-1/50 and -0.02
Because:
-(1/50) = -(0.02) = -0.02

the least value is negative 9 x 10-³
the greatest value is positive 7 x 10-⁵
Answer:
2,4,1,3
Step-by-step explanation:
So, I labeled each one, 1,2,3, and 4 respectively.
1, when expanded is 0.000005
2 is equal to -0.009
3 is simple 0.00007
and 4 is -0.0000002
Obviously the one of the negative numbers is the smallest. The bigger number with the negative sign is more negative because it is farther away from one on the number line. Therefore 2 is the smallest. That makes 4 the second smallest. 3 is larger than 1 because there are less zeros to the first non-zero digit. That places the order from least to greatest as:
2,4,1,3
If PQRS is a parallelogram and PQ=9x+1 and RS=13x-11, solve for x.
Applying the definition of a parallelogram, the value of x in the length of the sides of the given parallelogram is: x = 3.
What is a Parallelogram?A parallelogram is a quadrilateral that has two pairs of opposite sides that are congruent to each other.
Given the following:
PQ = 9x + 1RS = 13x - 11Find x by creating an equation:
PQ = RS (congruent sides)
Substitute
9x + 1 = 13x - 11
Combine like terms
9x - 13x = -1 - 11
-4x = - 12
x = 3
Therefore, applying the definition of a parallelogram, the value of x in the length of the sides of the given parallelogram is: x = 3.

Answer:
False
Step-by-step explanation:

Question 5 options:
C(14, 5)
C(-10+5)
C ( 10,9)
C(-14,8)
Step-by-step explanation:
Since you added 12 to the x coordinate and subtracted 7 from the y coordinate, to undo that translation, you need to subtract 12 from the x coordinate of the image and add 7 to the y coordinate of the image.
This gives you that C=(-2-12, 1+7)=(-14, 8)
The surface area of a cylinder is approximately 640.56 square meters. The radius of the cylinder is 5 meters less than the height of the cylinder. To the nearest whole meter, what are the radius and height of the cylinder?
the radius is approximately 6 meters,
height is approximately 11 meters
The radius of cylinder = 6 meter.
The height of cylinder = 11 meter.
What is cylinder?A cylinder is a "three-dimensional object with two round flat bases and one curved side. It has a curved surface in the middle. The base and the top surface are identical".
According to the question,
Surface area of the cylinder = 640.56 m²
Let the height of the cylinder = x meters
Let the radius of the cylinder = (x-5)meters
Formula for surface area of cylinder = 2πrh ( where 'r' is the radius of the cylinder and 'h' height of the cylinder)
640.56 = 2(3.14)(x-5)(x)
640.56/(6.28) = x² - 5x
x² - 5x =102
x² - 5x - 102 =0
using quadratic equation, [-b±√(b² - 4ac)]/2a.
b = -5; a=1; c=102
x =[-(-5) ±√(-5)² - 4(1)(102)]/2
= [5 ± √433]/2
x = 11 and -7
since x=-7 neglect negative value, we get x=11.
The height of the cylinder is 11 meters
The radius of the cylinder is (11 - 5) = 6 meters.
Hence, The radius of cylinder = 6 meter.
The height of cylinder = 11 meter.
