Answer:

Option (B) 4 = 2x - 3

Step-by-step explanation:

Let distance travel by Marcus be "x" miles

Then, according to question

Distanced travelled by Jenney will be

twice of "x" minus 3.

Distance travelled by Jenny = 2x - 3.

Also, it is given that Jenny has travelled 4 miles.

then, 4 = 2x - 3. So, here option (B) is the correct option.

Answer:

B

Step-by-step explanation:

The steps to solve the inequality 3b + 8 ≥ 14 involve subtracting 8, then dividing by 3 to find b ≥ 2.

To solve the inequality 3b + 8 ≥ 14:

Subtract 8 from both sides: 3b + 8 - 8 ≥ 14 - 8, which simplifies to 3b ≥ 6.

Divide by 3 to isolate b: 3b/3 ≥ 6/3, giving you b ≥ 2.

Therefore, the solution to the inequality is b ≥ 2, indicating that b must be greater than or equal to 2.

Answer

D, 12m

Step-by-step explanation:

Answer:

12 m

Step-by-step explanation:

Area of a triangle is:

A = ½ bh

Given that h = b - 5 and A = 42:

42 = ½ b (b - 5)

84 = b² - 5b

0 = b² - 5b - 84

0 = (b + 7) (b - 12)

b = -7, 12

The length of the base can't be negative, so b = 12 m.

Answer:

See below,

Step-by-step explanation:

2x > 50

Dividing both sides by 2:

x > 25 which is Graph C  (because the red line is to the right of 25).

x + 6 < 32

x < 32 - 6

x < 26  which is Graph B .

Ques 1)

The first inequality is given by:

                  [tex]2x>50[/tex]

on dividing both side of the inequality by 2 we obtain:

               [tex]x>25[/tex]

i.e. the solution set is the set of all the real values which are strictly greater than 25.

i.e. the shaded region is to the tight of 25 and there will be a open circle at 25 (Since the inequality is strict inequality )

i.e. the solution set is: (25,∞)

Hence, the graph which represents the inequality 2x>50 is: Graph C.

Ques 2)

The second inequality is given by:

             [tex]x+6<32[/tex]

on subtracting both side of the inequality by 6 we get:

                 [tex]x+6-6<32-6\\\\i.e.\\\\x+0<26\\\\i.e.\\\\x<26[/tex]

This means that the solution set is the set of all the real values which are strictly less than 26.

i.e. the shaded region is to the left of 26 and there will be a open circle at 26 ( since the inequality is strict)

i.e. the solution set is: (-∞,26)

The graph which represents the inequality x+6<32 is:  Graph B

Answer:

40 MPH (Miles Per Hour)

Step-by-step explanation:

Well i will put it in simple terms. Put 2/3 into a decimal point, which for this fraction is 0.66666666667 (the 6 is infinite basically). Then you multiply it by 60, because you know it goes in that distance in one minute and 60 minutes makes a hour, which equals 40. So the answer is 40 MPH.

40 miles per hour.

To determine how many miles per hour a bird is flying when it covers 2/3 of a mile per minute, we can follow a simple conversion. Since there are 60 minutes in an hour, we need to multiply 2/3 by 60.

Let's do the calculation:

(2/3 mile/minute) times 60 minutes/hour = 40 miles/hour

This means that when a bird flies 2/3 of a mile per minute, it is equivalent to flying at a speed of 40 miles per hour.

Answer:

86

Step-by-step explanation:

To evaluate f(- 9) substitute x = - 9 into f(x)

f(- 9) = (- 9)² + 5 = 81 + 5 = 86

The correct answer is not listed in the provided options. f(-9) is found by substituting -9 into the function f(x) = x² + 5, giving us (-9)² + 5, which results in 86. The provided options do not include the correct answer, suggesting there may be a mistake.

To find f(-9) when f(x) = x² + 5, we simply substitute -9 for x in the function and calculate the result.

Step-by-Step Solution:

Replace every x in the function with -9: f(-9) = (-9)² + 5.

Calculate the square of -9: (-9)² = 81.

Add 5 to the result: 81 + 5 = 86.

Thus, f(-9) = 86.

The correct answer is not listed in the provided options, so there might be a typo in the original function or the options given.

Answer:

3x

Step-by-step explanation:

-(x-1) +5 = 2(x+3) - c

C is the unknown term

Distribute the negative sign and the 2

-x+1 +5 = 2x+6 -c

Combine like terms

-x+6 = 2x +6-c

Solve for c

Add x to each side

-x+x +6 = 2x+x +6-c

6 = 3x+6 -c

Add c to each side

6+c = 3x +6 -c+c

c+6 = 3x+6

Subtract 6 from each side

c+6-6 = 3x+6-6

c = 3x

When c = 3x, the two sides of the equation are equal, and the solutions are infinite.

Answer: [tex]3x[/tex]

Step-by-step explanation:

Let be "z" the missing term:

[tex]-(x-1)+5=2(x+3)-z[/tex]

For the system to have infinite number of solutions, [tex]2(x+3)-z[/tex] must be equal to [tex]-(x-1)+5[/tex].

Now you must solve for "z". Apply Distributive property:

[tex]-x+1+5=2x+6-z[/tex]

Add the like terms on the left side:

[tex]-x+6=2x+6-z[/tex]

Now you need to subtract [tex]2x[/tex] and 6 from both sides of the equation and finally you can multiply both sides by -1. Then:

[tex]-x+6-2x-6=2x+6-z-2x-6\\\\(-1)-3x=-z(-1)\\\\z=3x[/tex]

In mathematics, notation like V(x) generally represents a function. Whether it is indeed a function depends on its definition and if every input x corresponds to exactly one output.

In mathematics, V(x) can indeed be a function. The notation V(x) generally represents a function named 'V' that takes an input 'x'. Whether it represents a function in a particular context depends on how it is defined. For a relationship to be a function, every input x must correspond to exactly one output in the function V. For instance, if V(x) is defined as x², then it IS a function, because each input x yields a specific output, which is the square of x.

x=4

Answer:

Step-by-step explanation:

We could multiply the first equation by -3 and, separately, multiply the second equation by 4.  The result would be:

-12x - 15y = -21

12x  - 8y = -48

the x terms now cancel.  The result is:

- 15y = -21

- 8y = -48

----------------

-23y = -69, or y = 3.  If y = 3, then 3x - 2y = -12 becomes:

3x - 2(3) = -12, or

3x - 6 = -12, or    3x = -6, and so x = -2.

The solution is (-2, 3).

Answer:

In the slot for 4x + 5y = 7 is -3. Which makes -21.

In the slot for 3x-2y=-12 is 4. Which makes -48.

Step-by-step explanation:

When you add the -21 and -48 you get -69.

The solution is (-2, 3)

0.86

The hundredths place is the second digit after the decimal point.  It is the 6 in this case.

Since the next digit (3) is 4 or less, the hundredths place stays the same and the rest is basically just cut off, leaving 0.86.

If the next digit (3) were 5 or more, the hundredths place would have gone up 1 (to 7) and the rest would have been cut off, giving a final result of 0.87

The decimal numeral system is the most widely used system for representing both integer and non-integer values. When 0.8637 is rounded to the nearest hundredth​ the number will be 0.86.

The decimal numeral system is the most widely used system for representing both integer and non-integer values. It is Hindu–Arabic numeral system's expansion to non-integer numbers. Decimal notation is the method of representing numbers in the decimal system.

A decimal number is rounded off based on its preceding number if the preceding number is greater than 5 then the number is rounded off to the next number, but if it's not, then the number is left in the same way.

Therefore, when 0.8637 is rounded to the nearest hundredth​ the number will become,

0.8637 ≈ 0.86

Hence, when 0.86 is rounded to the nearest hundredth​ the number will be 0.86.

Step-by-step explanation:

The equation of the fourth side of the considered parallelogram is y = 2x + 10

Parallel lines have same slope, since slope is like measure of steepness and since parallel lines are of same steepness, thus, are of same slope.

Since given parallel line has equation [tex]y = 2x + 2[/tex], thus its slope is 2 and thus, the slope of the needed line is 2 too.

If the slope of a line is m and the y-intercept is c, then the equation of that straight line is given as:

y = mx + c

To find the slope of a line, we find the rate at which the value of 'y' is increasing as we increase the value of 'x' by one unit.

A parallelogram is a four sided polygon, whose opposite sides are parallel to each other.

The slopes of y = 0 and y = 2 is same. (being 0)

Therefore the fourth side would've same slope as that of y = 2x.

The slope of y = 2x is 2 (the coefficient of x)

Thus, the equation of fourth side would be:

y = 2x + c for some real number c

Let we find the coordinates of four vertices. These are intersections of the equations of the adjacent sides.

Intersection of y = 0:

Putting y = 0 gives 0 = 2x, or x = 0

Thus, the intersection is on (0,0)

Putting y = 0 gives 0 = 2x + c, or x = -c/2

Thus, the intersection is on (-c/2, 0)

Intersection of y = 2:

Putting y = 2 gives 2 = 2x, or x = 1
Thus, the intersection is on (1,2)

Putting y = 2 gives 2 = 2x + c, or x = (2-c)/2

Thus, the intersection is on ((2-c)/2, 2)

Thus, the four vertices' coordinates are:

(0,0), (1,2), (-c/2, 0), and ( (2-c)/2, 0)

Let we name these points, as:

A(0,0), B(-c/2, 0),  C( (2-c)/2, 2) and D(1,2),

AB is line y = 0 (known from the y-coordinates of A and B)

Similarly, CD is line y = 2 (known from the y-coordinates of C and D)

AD and BC are parallel. (these are going to be other pair of parallel sides).

The length of AD is:

[tex]\sqrt{(1-0)^2 + (2-0)^2} = \sqrt{5} \: \rm units[/tex]

A parallelogram has its parallel sides of equal length.

Thus, length of BC is of √5 units too.

Since this parallelogram has two side lengths of 5 units, adn as AD and BC are not those sides, so we must have:

|AB| = |CD| = 5 units.

Length of AB is:

[tex]|AB| = \sqrt{(-c/2 - 0)^2 + (0 - 0)^2 } = c/2 = 5\\c = 10[/tex]

Thus, the equation of the fourth line is:

[tex]y = 2x + 10[/tex]

The graph of the considered parallelogram is given below.

Thus, the equation of the fourth side of the considered parallelogram is y = 2x + 10

To find the length of a rectangle with an area of 55 square feet and a width of 3 1/7 feet, you divide the area by the width after converting the mixed number to an improper fraction. Length = 55 / (22/7), which simplifies to 17.5 feet.

To find the length of the rectangle when the area is 55 square feet and the width is 3 1/7 feet, you can use the formula for the area of a rectangle, which is Area = Length × Width. You will first need to convert the width to an improper fraction, where 3 1/7 feet is 22/7 feet. Then, use the area to find the length:

Area = Length × Width

55 = Length × (22/7)

To find the Length, divide both sides by the width: Length = 55 / (22/7)

Multiply by the reciprocal of the width: Length = 55 × (7/22)

Simplify to find the Length: Length = 55/22 × 7

Length = 2.5 × 7

Length = 17.5 feet

Therefore, the length of the rectangle is 17.5 feet.
