Write an equation of a line that passes through point (5, 3) and is perpendicular to the line 2y = 5x – 8.

anastassius [24]

Answer:

y= -2/5+5

Step-by-step explanation:

A line must always be written in the form y= and the line given is not. Dividing both sides of the equation by 2 you get y=5/2x-4. This is the equation of the line given.

Perpendicular line have gradients that, when they are multiplied, they are equal to -1

The line given multiplied by the gradient of the line(the one required to find)= - 1. That is 5/2×line= -1.

Dividing both sides of the equation by 5/2 you'll get - 2/5. This is the gradient of the line required.

Using the general formula y=mx+c substitute the gradient into the equation. You'll get something like this y= -2/5x+c.

Substitute the given point into the equation. You'll get something like this 3= -2/5(5)+c.

Calculate the value of c. You'll get c=5.

Substitute the value of c into the original equation. You'll get something like this y= -2/5+5

This is the equation: y= -2/5+5

PLEASE HELP

Answer:

$(\sqrt{30}-2\sqrt{5})\ m$

Step-by-step explanation:

we know that

The length of the side, s, of a cube with a surface area, SA is equal to the formula

$s=\sqrt{\frac{SA}{6}}$

Step 1

Find the length of the side, s, of a cube with a surface area of $180\ m^{2}$

we have

$SA=180\ m^{2}$

substitute in the formula

$s=\sqrt{\frac{180}{6}}$

$s=\sqrt{30}\ m$

Step 2

Find the length of the side, s, of a cube with a surface area of $120\ m^{2}$

we have

$SA=120\ m^{2}$

substitute in the formula

$s=\sqrt{\frac{120}{6}}$

$s=\sqrt{20}=2\sqrt{5}\ m$

Step 3

Find the difference of the length sides

$(\sqrt{30}-2\sqrt{5})\ m$

Estimate the solution of the linear system of equations by graphing. Give approximate coordinate values to the nearest integer.

lubasha [3.4K]

The solutions to the system of equations is $(3.8,-1.6)$

Explanation:

Given the system of equations are $3y=-6x+18$ and $-35=-7x+5y$

We need to determine the solution to the system of equations.

Let us plot the equation $3y=-6x+18$ in the graph.

When $x=0$ , we get, $3y=18 \implies y=6$

When $y=0$ , we get, $-18=-6x \implies x=3$

Thus, the coordinates are (0,6) and (3,0)

Let us plot the equation $-35=-7x+5y$ in the graph.

When $x=0$ , we get, $-35=5y \implies -7=y$

When $y=0$ , we get, $-35=-7x \implies 5=x$

Thus, the coordinates are (0,-7) and (5,0)

The solution to the system of equations is the point of intersection of the two lines.

Thus, the lines intersect at the point $(3.824,-1.647)$

The approximate values of the point is $(3.8,-1.6)$

Thus, the solution is $(3.8,-1.6)$

Let P be the set of polynomials. Let a, b, c, and d be elements of P such that band d are non-zero elements of P. Which of the f

lozanna [386]

Answer:

D. The sum is a rational expression.

Step-by-step explanation:

the given expression is a/b +c/d

so in the question it is given that b and d are non zero values

a/b is rational number and c/d is a rational number

so if both are rational number , so we know that the sum of rational number is also a rational number.

The right option is D. The sum is a rational expression
