Step-by-step explanation:

3−2(x+1)=2x−7

3+(−2)(x)+(−2)(1)=2x+−7(Distribute)

3+−2x+−2=2x+−7

(−2x)+(3+−2)=2x−7(Combine Like Terms)

−2x+1=2x−7

−2x+1=2x−7

Step 2: Subtract 2x from both sides.

−2x+1−2x=2x−7−2x

−4x+1=−7

Step 3: Subtract 1 from both sides.

−4x+1−1=−7−1

−4x=−8

Step 4: Divide both sides by -4.

−4x−4=−8−4

Answer:

Independent variable: distance

Dependent variable: number of letters recognized on an eye chart

Step-by-step explanation:

Independent variables are stand-alone. This means that it does not depend on another variable but affects the dependent variable.

Dependent variables are dependent on another variable. When the independent variable changes, dependent variables are changed.

Since the hypothesis is that the distance affects the number of letters recognized,

the distance causes a change in the number of letters recognized not the other way around.

Thus, the dependent variable is the number of letters recognized on the eye chart while the independent variable is the distance.

Answer:

The function f(x) was translated right 3 units and up 2 units.

Step-by-step explanation:

F(x)=(2/3)^x

If we move it right for 3 units, we get

f(x)= (2/3)^(x-3)

If we move up 2 units , we get

g(x)= (2/3)^(x-3) +2

Answer:

109.6cm^2

Step-by-step explanation:

To find the area of a trapezoid the formula is (a+b)/2*h so for this problem, (12+15.4)/2*8= 27.4/2*8= 13.7*8=109.6cm^2

Answer:x=30

Step-by-step explanation:

So first you have to find x so add all your sides together:

Equation: 45+2x+0.5x+x=150

Combine like terms: 45+3.5x=150

Subtract 45 from -45 -45

both sides: 3.5x=105

Then divide by 3.5: x=30

Now that you have your x substitute it in:

2(30)=60

0.5(30)=15

and the last one is x=30

And there you have all your sides! If you wanna check it just add up all the sides and it should equal 150.

Answer:The equation of any straight line, called a linear equation, can be written as: y = mx + b, where m is the slope of the line and b is the y-intercept. The y-intercept of this line is the value of y at the point where the line crosses the y axis.

Answer

1360

Step-by-step explanation:

4x10 is 40 so you'd have to multiply 40x34 which is 1360

136×10 is the amount of water used by the airplane to deliver 34

trips.

Multiplication is a method of finding the product of two or more numbers

Given that Airplanes are sometimes used to fight fires.

A certain airplane can deliver 4 x 10 liters of water in one trip.

We need to find how much water can the  airplane deliver in 34

trips

Let us find the water used for one trip.

1 trip is 4 x 10 liters which is 40 litres.

Now we have to find for 34 trips.

We have to multiply 34 with 40 litres

34×40

Thirty four times forty

1360

Now we have to convert it to the scientific notation 136×10

Hence, 136×10 is the amount of water used by the airplane to deliver 34

trips.

Answer:

The person will have P-4 paintings left      

Step-by-step explanation:

We are told that the total number of painters who entered into the painting donation agreement to the local museum is 12 painters

and they all agreed to donate 48 paintings equally

so each painter will donate

48/12= 4paintings

Since this person already had P paintings in his art collection

his painting will reduce by the 4 paintings he denoted to the local museum\

hence he will have

P-4 paintings remaining

Answer:

4.5 is the range

Step-by-step explanation:

Ok, so it's asking for range, Range means The Highest number minus the smallest number.

What is the highest number? it's "2.3"

What is the lowest number? it's "-2.2"

so subtract those numbers and you get your answer!

Wait... why is the range 4.5? well, you do 2.3-(-2.2) when there are 2 minuses, you switch it to a + sign. so, 2.3+2.2=4.5!

Step-by-step explanation:

(1-3i)-(2-i)=

1-2-3i+i=

-1-2i

1-2-3i+i

= -1-2i

Step-by-step explanation:

I simplified it in a simple way by arranging like terms together and did the calculation. Here the like term of 1 is -2 and for -3i it's i. so 1-2= -1 and -3i+i= -2i according to integers rule.

Answer:

29/24π

Step-by-step explanation:

To get coterminal angles, you simply have to add or subtract 2π

In this problem, we are looking for a coterminal angle that is between

0 and 2π, so we will add 2π to −19/24π.

−19/24π+2π

=

−19/24π+48/24π

=

29/24π

29/24π

is the answer to the question.

[tex]\frac{11\pi }{4}[/tex] is the coterminal between of [tex]\frac{19\pi }{4}[/tex] between (0, 2[tex]\pi[/tex]).

Coterminal angles are the angles that have the same initial side and share the terminal sides.

To find the coterminal angle of an angle, we just add or subtract multiples of 360 degrees from the given angles.

According to the given question.

We have

Angle = [tex]\frac{19\pi }{4}[/tex]

Since, the coterminal angle is to be between 0 and 2π.

Therefore, we subtract 2π from [tex]\frac{19\pi }{4}[/tex]to get coterminal angle.

⇒ [tex]\frac{19\pi }{4} -2\pi[/tex] [tex]= \frac{19\pi -8\pi }{4} =\frac{11\pi }{4}[/tex]

Hence, [tex]\frac{11\pi }{4}[/tex] is the coterminal between of [tex]\frac{19\pi }{4}[/tex] between (0, 2[tex]\pi[/tex]).

Answer:

(-4,-0.5)

Step-by-step explanation:

midpoint = ((x1+x2)/2, (y1+y2)/2)

               = ((-5+-3)/2, (-4+3)/2)

               = (-8/2, -1/2)

               = (-4,-0.5)

x= 1 + 5 √2

x= 1 - 5 √2

The values of x in the expression are x = 1 + √51 and x = 1 – √51.

We have,

Expanding the left side of the equation, we get:

(x – 1)2 = x2 – 2x + 1

So, we have:

x2 – 2x + 1 = 50

Subtracting 50 from both sides, we get:

x2 – 2x – 49 = 0

Now, we can use the quadratic formula to solve for x:

x = [2 ± √(22 – 4(1)(–49))] / (2)

x = [2 ± √(204)] / (2)

x = [2 ± 2√51] / (2)

x = 1 ± √51

Therefore,

The values of x are x = 1 + √51 and x = 1 – √51.
