Answer:

[tex]y=-\frac{3}{2}x+1[/tex]

Step-by-step explanation:

Slope-intercept form means

[tex]y=mx+c[/tex]

where m is given its the slope which is [tex]-\frac{3}{2}[/tex] and we have the coordinates x and y which is (4, -5) and we need to find the value of c which is the y-intercept so we insert all these values into the equation so ,

[tex]y=mx+c[/tex]

[tex]-5 = -\frac{3}{2}(4)+c[/tex]

[tex]-5=-6+c[/tex]

[tex]c=1[/tex]

now we know the value of slope which is given [tex]-\frac{3}{2}[/tex] and we found the value of which is 1 so we put these values into our original slope-intercept form equation

[tex]y=mx+c\\\\y=-\frac{3}{2}x+1[/tex]

The solution to a system of equations is where the lines intersect, which are: A. (-2,0) C. (1, -3)

When a system of equations is represented on a graph, the solution to the system of equations is simply the coordinates of the points where the line of the equations intersect.

Thus, the lines intersect at (-2,0) and (1, -3). Therefore, the solution to the system of equations are: A. (-2,0) C. (1, -3)

2421 × 60 = 145260

2421 × 60% = 1452.6

Step-by-step explanation:

Answer:

A

Step-by-step explanation:

We can solve for y for both of the lines' equations to get the point-slope form.

L1: [tex]y=\frac{-2}{3} x+\frac{8}{3}[/tex]

L2:[tex]y=\frac{-3}{2}x+\frac{7}{2}[/tex]

So, the slopes of the two lines are [tex]\frac{-2}{3}[/tex] and [tex]\frac{-3}{2}[/tex].

Remember that parallel lines have the same slope, and perpendicular lines have opposite and reciprocal slopes. These slopes are reciprocal but not opposite.

Answer:

x = 1  ,y = -2

Step-by-step explanation:

Solve the following system:

{-4 y - 3 x = 5 | (equation 1)

3 y - 2 x = -8 | (equation 2)

Subtract 2/3 × (equation 1) from equation 2:

{-(3 x) - 4 y = 5 | (equation 1)

0 x+(17 y)/3 = -34/3 | (equation 2)

Multiply equation 2 by 3/17:

{-(3 x) - 4 y = 5 | (equation 1)

0 x+y = -2 | (equation 2)

Add 4 × (equation 2) to equation 1:

{-(3 x)+0 y = -3 | (equation 1)

0 x+y = -2 | (equation 2)

Divide equation 1 by -3:

{x+0 y = 1 | (equation 1)

0 x+y = -2 | (equation 2)

Collect results:

Answer: {x = 1  ,y = -2

Answer and explanation:

Stellar is a Brazilian cryptocurrency that is used to facilitate low cost and flexible payment. It was renamed lumens and is denoted XLM.

One stellar lumen is currently equal to $0.219096

For the purpose of the question and since it does not specify exchange rates for each bank, let's assume:

Bank A= 0.219097 to 1 US dollar

Bank B= 0.219099 to 1 US dollar

Using Bank A to exchange $1700 for stellars= $1700*0.219097= 372.464 stellars

Using Bank B to exchange $1700 for stellars= $1700*0.229042= 389.3714 stellars

From the above, we can see that Bank B has a better exchange rate as it is cheaper than Bank A(gives more stellar) . She should therefore use Bank B for her exchange.

Common factors between the two numbers is 3 and 1.

Step-by-step explanation:

The factors of 42 are 42, 21, 14, 7, 6, 3, 2, 1.

The factors of 45 are 45, 15, 9, 5, 3, 1.

The value of the prime number which is a factor of 42 and 45 would be  3.

Used a concept of prime number that states,

A prime number is a whole number greater than 1 whose only factors are 1 and itself. A factor is a whole number that can be divided evenly into another number. Numbers that have more than two factors are called composite numbers.

Given that the two numbers are 42 and 45

Now, factors of numbers 42 and 45 are,

The Factor of 42 are

1, 2, 3, 6, 7, 14, 21, 42

And, The factors of 45 are

1, 3, 5, 9, 15, 45

So, the prime number that is a factor of 42 and 45 is 3.

y = -3/2x + 5/2

Explanation-

slope intercept form is y = mx + b

so we have to solve the equation for y

Answer:

King size(x): 3

Regular size(y): 2

Steps:

System of Equations:

x+y = 5

3.75x+1.75y = 14.75

Multiply 3.75 on all sides.

3.75x+3.75y = 18.75

3.75x+1.75y = 14.75

Subtract top and bottom

            2y  = 4

            /2      /2

             y   =  2

After you know regular size amount, figure out king size ----3.

Hint: | Put the fractions in 2 x + 1/x over a common denominator.

Put each term in 2 x + 1/x over the common denominator x: 2 x + 1/x = (2 x^2)/x + 1/x:

((2 x^2)/x + 1/x)^2

Hint: | Combine (2 x^2)/x + 1/x into a single fraction.

(2 x^2)/x + 1/x = (2 x^2 + 1)/x:

((2 x^2 + 1)/x)^2

Hint: | Distribute exponents over quotients in ((2 x^2 + 1)/x)^2.
