None of the given equations are perpendicular to the equation '5y = 2x +4'. This is because perpendicular lines have reciprocal, negative slopes and none of the given lines meet this criteria.

To find the equations that are "perpendicular" to the given equation 5y = 2x +4, we first need to find out the slope of the given equation. The slope of the equation is obtained by rearranging it into the y=mx+b form where m stands for the slope. Thus, y=(2/5)x+4/5, which gives us a slope (m) of 2/5.

Perpendicular lines have slopes that are negative reciprocals of each other. So, for a line to be perpendicular to the given line, it should have a slope of -5/2.

Given the equations 7 y = 6x + 8, 4y = 8, and y + 7 = 3x, let's find out their slopes. The slope for the first equation is 6/7, for the second equation is undefined as it's a horizontal line, and for the third equation is 3. Hence, none of these lines are perpendicular to the given line. Similarly, none of the lines Y2 = -173.5+ 4.83x − 2(16.4) and line Y3 = -173.5+ 4.83x + 2(16.4) don't have a slope of -5/2 and hence, are not perpendicular to the given line.

The equation of the line with a slope of 2/3 and y-intercept of 4 is y = 2/3x + 4.

The equation of a line in slope-intercept form (which is the most common form we deal with in algebra) is y = mx + b, where m is the slope and b is the y-intercept.

In this case, you're given that the slope (m) is 2/3 and the y-intercept (b) is 4. Substituting these values into the equation gives you the equation of the line: y = 2/3x + 4.

This is the equation that represents the given line

Final answer:

The equation of the line with a slope of 2/3 and a y-intercept of 4 is y = 2/3x + 4.

Explanation:

To find the equation of a line with a slope of ⅓ and a y-intercept of 4, we can use the slope-intercept form of a line, which is y = mx + b where m is the slope and b is the y-intercept.

The given slope is ⅓, so m = ⅓. Given that the y-intercept is 4, b = 4.

Plugging these values into the slope-intercept equation, we get y = ⅓x + 4, which is the equation of the desired line.

The equation of a line is a mathematical expression that describes the relationship between the independent variable (x) and the dependent variable (y) for points on that line in a Cartesian coordinate system. It allows you to represent a straight line graphically on a two-dimensional plane.

Answer:

[tex]4.5375*10^1[/tex]

Step-by-step explanation:

we know that

[tex]45\frac{3}{8}=45+\frac{3}{8}=45+0.375=45.375[/tex]

Convert decimal number in scientific notation

A number expressed in  scientific notation   has the form

[tex]a*10^{n}[/tex]

where

[tex]1\leq a < 10[/tex]

n is a integer

Expressing 45.375 in this form means writing the number as a value between 1 and 10

so

For a=4.5375,n=1

[tex]45.375=4.5375*10^1[/tex]

Final answer:

The mixed number 45 3/8 can be expressed in scientific notation as 4.5375 *[tex]10^2[/tex] by first converting it to an improper fraction, then to a decimal, and finally moving the decimal point two places to the left.

Explanation:

To write the mixed number 45 3/8 in scientific notation, let's first convert it into an improper fraction and then into a decimal. The mixed number 45 3/8 is equivalent to (45 * 8 + 3) / 8, which simplifies to 363/8 or 45.375 as a decimal.

Now, to express this in scientific notation, we move the decimal point two places to the left so that the number falls between 1 and 10. As a result, we get 4.5375. Since we moved the decimal two places to the right, we multiplied by 10 to the power of 2([tex]10^2[/tex])

Finally, 45 3/8 in scientific notation is 4.5375 *( [tex]10^2[/tex] ).

The number that Dan wrote is two millions thirty five thousand, four

The correct number in expanded form is

[tex](2*10^6)+(3*10^5)+(5*10^4)+4=2,000,000+300,000+50,000+4=2,350,004[/tex]

Step-by-step explanation:

We can just make a ratio. 5:4 = x:12. We see x=15

The height of the tree = 15m.

let us say the height of the tree=h

in this problem,

the height of the sam can be treated as perpendicular of a right-angle triangle.

while his shadow can be treated as the base of the same triangle.

now, we need to calculate the angle of elevation α

it is the angle between the line of sight and the horizon.

hence,

the tangent of the angle of elevation α= height/length of the shadow

tanα= 5/4

tan α = height of the tree/length of the shadow of the tree

5/4 = h/12

h=15m

therefore, the height of the tree = 15m

Answer:

w=6

Step-by-step explanation:

3w+5=23

3w=23-5

3w=18

w=6

The solution to the equation 3w + 5 = 23 is w = 6.

The given equation is 3w + 5 = 23.

We need to solve for w.

Subtract 5 from both sides of the equation to isolate the term with 3w:

3w + 5 - 5 = 23 - 5

3w = 18

Divide both sides of the equation by 3 to solve for w:

(3w) / 3 = 18 / 3

This simplifies to:

w = 6

Therefore, the solution to the equation 3w + 5 = 23 is w = 6.

Answer:

The x-intercept is at -8 and the y-intercept is at -5.

Step-by-step explanation:

When you simplify 5x + 8y = 40 into y = mx + b form, you get y = -5/8x - 5.

Answer: x-intercept is (-8,0) and y-intercept is (0,-5)

Step-by-step explanation:

5x+8y=-40

To find the x-intercept, you plug in 0 in for y.

5x+8(0)=-40

5x=-40

Then solve for x

5x/5=-40/5

x=-8

The x-intercept is (-8,0)

To find the y-intercept, you plug in 0 in for x

5(0)+8y=-40

8y=-40

Solve for y

8y/8=-40/8

y=-5

y-intercept is (0,-5)
