Step-by-step explanation:

I am not sure who made the dots on the charts, but they are wrong.

y = 1/2 x + 3

domain means all valid values for x.

range means all valid values for y (the functional results).

x = 0

y = 1/2 × 0 + 3 = 3

x = 1

y = 1/2 × 1 + 3 = 3.5

x = 2

y = 1/2 × 2 + 3 = 4

x = 3

y = 1/2 × 3 + 3 = 4.5

x = 4

y = 1/2 × 4 + 3 = 5

so, the range is 3, 3.5, 4, 4.5, 5

y = x - 6

x = 10

y = 10 - 6 = 4

x = 12

y = 12 - 6 = 6

x = 14

y = 14 - 6 = 8

x = 16

y = 16 - 6 = 10

x = 18

y = 18 - 6 = 12

so, the range is 4, 6, 8, 10, 12

Answer:

7 to the power of 3/2

Step-by-step explanation:

7 is the same as 7¹ and [tex]\sqrt{7}[/tex] is the same as 7 to the power of 1/2

since the bases are both 7, we keep the base and add the exponents when we multiply with exponents, giving us:

7 to the power of 3/2

Answer:

289/216

Step-by-step explanation:

add the parentheses first

(2/3+3/4)×(3/6+4/9)=

17/12×17/18

then multiply

17/12×17/18=

286/216

2/3 + 3/4

= 2 × 4/3 × 4 + 3 × 3/4 × 3

= 8/12 + 9/12

= 8 + 9/12

= 17/12

For adding, subtracting, and comparing fractions, it is suitable to adjust both fractions to a common denominator. The common denominator you can calculate as the least common multiple of both denominators - LCM(3, 4) = 12. In practice, it is enough to find the common denominator by multiplying the denominators: 3 × 4 = 12. In the next intermediate step, the fraction result cannot be further simplified by canceling.

Add: 3/6 + 4/9

= 3 × 3/6 × 3 + 4 × 2/9 × 2

= 9/18 + 8/18

= 9 + 8/18

= 17/18

For adding, subtracting, and comparing fractions, it is suitable to adjust both fractions to a common denominator. The common denominator you can calculate as the least common multiple of both denominators - LCM(6, 9) = 18. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 6 × 9 = 54. In the next intermediate step, the fraction result cannot be further simplified by canceling.

2 = 17/12 × 17/18

= 17 × 17/12 × 18

= 289/216

Multiply both numerators and denominators. Result fraction keep to lowest possible denominator GCD(289, 216) = 1. In the next intermediate step, the fraction result cannot be further simplified by canceling.

Consider ABCD is a rhombus

We know that

All sides are equal in rhombus

=> AB=BC=CD=DA

and AC and BD are digonals

Given that

Diagonal and the side of the rhombus are equal.

=> AB = BC = CD = DA = AC

Diagonal AC divides the rhombus into two triangles .

They are ∆ BAC and ∆ DAC

In triangle BAC

BA=BC=AC,(Given)

=> < BAC=<ABC= < ACB =60°………(1)

Similarly in ∆DAC ,

DA=DC=AC

=><DAC=<ACD=<ADC=60°……….(2)

From (1) and (2)

<A=<BAC+< DAC=60°+60°=120°

and

< B= < ABC = 60°.

and

<C=<ACB+<ACD=60°+60°=120°

and

< D =<ADC=60°

Therefore, <A = 120° , <B = 60° ,<C = 120° ,<D = 60°

Answer:-

The measures of the all angles in the rhombus are 120° , 60° ,120° and 60°

Used formulae:-

all sides in a rhombus are equal

Answer:

Yes, B is correct, the horizontal line test is used to test if an INVERSE is a function.

Answer:

B

Step-by-step explanation:

the equal is correctly

3x + 1 = 2x + 4

what was done now :

2 x-blocks (2x) subtracted from the right side, and 1 numbered block subtracted from the left side.

to reestablish balance and equality of both sides, we need to do more the exact same things - just in the other sides.

2 x-blocks subtracted from the LEFT side, and 1 numbered block subtracted from the RIGHT side.

and that is answer B.

18/2-3/.75=15/1.25

The average speed of Even between two checkpoints is 9 miles per hour.

The distance covered by the particle or the body in an hour is called the average speed. It is a scalar quantity. It is the ratio of the total distance to the total time.

We know that the average speed formula is given as,

Average speed = Total distance / Total time

Running a marathon is Evan. Between two checkpoints, he wants to compute his average speed. He takes 0.75 hours to go to the 3-mile checkpoint and 2 hours to get to the 18-mile milestone.

The average speed is given as,

Average speed = 18 / 2

Average speed = 9 miles per hour

The average speed of Even between two checkpoints is 9 miles per hour.

More about the average speed link is given below.

Answer:

Each slice of pizza is 4 dollars

Step-by-step explanation:

you need to multiply 2.50$ by 3 to get the total of the drinks and subtract it by the overall total of 31.50 to get the total cost of the pizza or 24.00$. Then you divide 24.00$ by 6 since there are 3 people and they each get 2 slices of pizza giving you 4.00$ per slice of pizza.

Answer:

y = $238

Step-by-step explanation:

Given the equation,  y = 0.29x + 58

Where:

y = total cost of renting a car

x = number of miles driven

58 = initial cost or amount.

To find the estimated cost for renting a car if you plan on driving for 619 miles, substitute 619 as the value of x into the equation:

y = 0.29(619) + 58

y = 179.51 + 58

y = 237.51 or 238

Therefore, the estimated total cost for driving 619 miles is $238.

Let's say we had the massive number

6,230,000,000

which we can shorten it to saying "6.23 billion" and that allows us to drop all the extra zeros at the end.

When writing it in scientific notation, we would say [tex]6.23 \times 10^9[/tex] and the [tex]\times 10^9[/tex] portion indicates "times ten to the ninth power". This is the place holder for "billion". It means we'll move the decimal point 9 spots to the right to go from 6.23 back to the original massive number shown above.

In short, scientific notation allows us to represent really large numbers in a compact way. It's useful to be able to communicate to a friend about whatever number you're referring to. One application is trying to find vast distances in outer space which tend to be very larger numbers. There are many other applications for scientific notation.

The perpendicular bisector of the of the hypotenuse side forms a right

triangle with the hypotenuse and the longer leg of the of the triangle.

The ratio, of the length of the segment cut from the perpendicular bisector by the hypotenuse and the longer leg to the length of the longer leg, is 1 : 3

Reason:

The given parameters are;

An acute angle of the right triangle = 30°

Let R represent the length of the hypotenuse side, we have;

The length of the longer leg, [tex]L_{ll}[/tex] = R × cos(30°) = [tex]\dfrac{\sqrt{3} }{2} \cdot R[/tex]

The perpendicular bisector forms a right triangle with a leg length = R/2

The length of the hypotenuse formed by the bisector is therefore;[tex]R_{bisector} = \dfrac{\dfrac{R}{2} }{cos(30^{\circ})} = \dfrac{\dfrac{R}{2} }{\dfrac{\sqrt{3} }{2} } = \dfrac{R}{\sqrt{3} }[/tex]

The length, L, of the segment cut by the hypotenuse and the longer leg is therefore;

[tex]L= R_{bisector} \times sin(30^{\circ}) = \dfrac{1}{2} \times \dfrac{R}{\sqrt{3} } = \dfrac{R}{2 \cdot \sqrt{3} }[/tex]

The ratio, of the length of the segment cut from this perpendicular bisector by the hypotenuse and the longer leg to the length of the longer leg, r, is therefore;

[tex]r = \dfrac{L}{L_{ll}} = \dfrac{ \dfrac{R}{2 \cdot \sqrt{3} }}{\dfrac{\sqrt{3} }{2} \cdot R} = \dfrac{2 \cdot R}{2 \cdot \sqrt{3} \times \sqrt{3} \times R } = \dfrac{1}{3}[/tex]

The ratio, of the lengths, r = [tex]\dfrac{1}{3}[/tex], therefore, r = 1:3
