The option that describes Myra’s distance as time increases is increasing.

Looking at the table provided, it can be seen that as time passes, the distance ran by Myra increases. It can be seen that distance increases from 0.4miles to 0.8 miles when time increases from 2 seconds to 4 seconds.

Change in distance run per time = change in distance / change in time

(0.4 - 0) / (2 - 0)

0.4 / 2 = 0.2

Answer:

MN = 5

Step-by-step explanation:

From inspection of the given diagram:

Therefore:

[tex]\implies \sf MN+NR=MNR[/tex]

[tex]\implies 2.5x+x=5x-3[/tex]

[tex]\implies 3.5x=5x-3[/tex]

Add 3 to both sides:

[tex]\implies 3.5x+3=5x-3+3[/tex]

[tex]\implies 3.5x+3=5x[/tex]

Subtract 3.5x from both sides:

[tex]\implies 3.5x+3-3.5x=5x-3.5x[/tex]

[tex]\implies 3=1.5x[/tex]

[tex]\implies 1.5x=3[/tex]

Divide both sides by 1.5:

[tex]\implies 1.5x \div 1.5=3 \div 1.5[/tex]

[tex]\implies x=2[/tex]

Substitute the found value of x into the expression for MN:

[tex]\implies \textsf{MN}=2.5(2)[/tex]

Part A:  Expression for the distance in meters between given two birds using subtraction = 2.5 - (-2.5)

Part B: The distance between two birds using additive inverse 2.5- (-2.5) =5 meters

An expression is an combination of numbers and mathematical operations such as addition, subtraction, division and multiplication with equating any two terms.

Additive inverse : Additive inverse of an number a is the number that  when adds to a gives zero .

Let b be additive inverse of a, then a + b =0

Then, b = -a

Given two birds A and B are at  points x= -2.5 and  y = 2.5 respectively

Therefore,  the expression for the distance in between given two birds

           = y - x  = 2.5- (-2.5)

We an clearly see that  -2.5 is additive inverse of 2.5

Distance between the two birds = 2.5 -(-2.5) =2.5 +2.5 = 5 meters

Therefore, the expression for distance between the two birds A and B is 2.5-(-2.5) and the distance is 5 meters.

Answer:

x = 0.25

Step-by-step explanation:

[tex]9\sqrt{x} =5-2x[/tex]

[tex]81x = 25 - 20x + 4x^{2}[/tex]

[tex]0=4x^{2} -101x+25[/tex]

[tex]0 = 4x^{2} -1x-100x+25[/tex]

[tex]0=x(4x-1)-25(4x-1)\\0=(x-25)(4x-1)[/tex]

[tex]x=25,\frac{1}{4}[/tex]

[tex]2*25+9\sqrt{25} =5\\50+9*5=5\\50+45=5\\95=5[/tex]

[tex]2*\frac{1}{4}+9\sqrt{\frac{1}{4} } =5 \\0.5+9*\frac{1}{2} =5\\0.5+4.5=5\\5=5[/tex]

Answer:

[tex]x=\dfrac{1}{4}[/tex]

Step-by-step explanation:

Given equation:

[tex]2x+9\sqrt{x}=5[/tex]

Subtract 2x from both sides to isolate the square root:

[tex]\implies 2x+9\sqrt{x}-2x=5-2x[/tex]

[tex]\implies 9\sqrt{x}=5-2x[/tex]

Square both sides to eliminate the square root:

[tex]\implies (9\sqrt{x})^2=(5-2x)^2[/tex]

[tex]\implies 81x=(5-2x)(5-2x)[/tex]

[tex]\implies 81x=25-20x+4x^2[/tex]

Subtract 81x from both sides:

[tex]\implies 81x-81x=25-20x+4x^2-81x[/tex]

[tex]\implies 0=25-101x+4x^2[/tex]

[tex]\implies4x^2-101x+25=0[/tex]

To factor a quadratic in the form [tex]ax^2+bx+c[/tex], find two numbers that multiply to [tex]ac[/tex] and sum to [tex]b[/tex]:

[tex]\implies ac=4 \cdot 25=100[/tex]

[tex]\implies b=-101[/tex]

Therefore, the two numbers are -1 and -100 as:

[tex]\implies -1 \cdot -100=100=a[/tex]

[tex]\implies -1+(-100)=-101 =b[/tex]

Rewrite [tex]b[/tex] as the sum of these two numbers:

[tex]\implies4x^2-x-100x+25=0[/tex]

Factor the first two terms and the last two terms separately:

[tex]\implies x(4x-1)-25(4x-1)=0[/tex]

Factor out the common term (4x - 1):

[tex]\implies (x-25)(4x-1)=0[/tex]

Apply the zero-product property:

[tex](x-25)=0 \implies x=25[/tex]

[tex](4x-1)=0 \implies x=\dfrac{1}{4}[/tex]

Input each solution into the original equation to check its validity:

[tex]\begin{aligned}x=25 \implies 2(25)+9\sqrt{25}&=5\\50+9(5)&=5\\50+45&=5\\95 & \neq 5\end{aligned}[/tex]

Therefore, x = 25 is not a valid solution.

[tex]\begin{aligned}x=\dfrac{1}{4}\implies 2\left(\dfrac{1}{4}\right)+9\sqrt{\dfrac{1}{4}}&=5\\\dfrac{1}{2}+9(\dfrac{1}{2})&=5\\\dfrac{1}{2}+\dfrac{9}{2}&=5\\\dfrac{10}{2}&=5\\5 & = 5\end{aligned}[/tex]

Therefore x = ¹/₄ is a valid solution.

Therefore, the only valid solution to the equation is x = ¹/₄.

The equation of a line perpendicular to y = 4x - 3 that passes through the point (2,-2) is y = -1/3x - 3/2

The equation of the line is given as

y = 4x - 3

Rewrite the equation as

y = 4x - 3

A linear equation is represented as

y = mx + c

Where

Slope = m

So, we have

m = 4

The slopes of perpendicular lines are opposite reciprocals

This means that

m2 = -1/m1

So, we have

m = -1/4

Evaluate

m = -1/4

The equation of the perpendicular line is then calculated as

y = m(x - x1) + y1

Where

(x1, y1) = (2, -2)

This gives

y = -1/4(x - 2) - 2

Evaluate

y = -1/3x + 1/2 - 2

Evaluate the sum and the difference

y = -1/3x - 3/2

So, the equation of a line perpendicular to y = 4x - 3 that passes through the point (2,-2) is y = -1/3x - 3/2

Hence, the required equation of a line perpendicular to y = 4x - 3 that passes through the point (2,-2) is y = -1/3x - 3/2
