The equation, y=4x+15 represents the relationship shown in the graph.
Finger [1]3 years ago
4 0

Answer:

4. -4x+y=15

Step-by-step explanation:

We have been given a graph of a linear function and we are asked to find the correct equation representing the relationship shown in the graph.

Since we know that the standard form of an equation is in form: Ax+By=C, where A, B and C are integers.

First of all we will find the slope of our line and write equation of line in slope-intercept form. Then we will change it into standard form.

m=\frac{y_2-y_1}{x_2-x_1}

m=\frac{23-15}{2-0}

m=\frac{8}{2}=4

Slope of our line is 4. We can see that y-intercept (b) is 15. Now let us write equation of our line in slope-intercept form.

y=mx+b

y=4x+15

Now we will change our given equation into standard form by subtracting 4x from both sides of our equation.

-4x+y=4x+15-4x

-4x+y=15    

Therefore, the equation -4x+y=15 represents the relationship shown in the graph in standard form and 4th option is the correct choice.

Answer:

  6.5e^(i·(-157.38°)) ≈ 6.5e^(-2.7468i)

Step-by-step explanation:

A suitable calculator can find the value of this ratio for you.

  ((2+3i)/(1-i))² = -6 -2.5i ≈ 6.5∠-157.38° ≈ 6.5e^(-2.7468i)

Louie is trying to find a rectangular canvas for his art project. Its height must measure 18 inches and form a 48° angle with th
KengaRu [80]

Answer:

27 inches

Step-by-step explanation:

To find the length of the diagonal, we just need to use the cosine relation of the 48° angle.

The adjacent side to the angle is the height of the canvas, and the hypotenuse formed is the diagonal of the canvas. So, we have that:

cos(48) = height / diagonal

0.6691 = 18 / diagonal

diagonal = 18 / 0.6691 = 26.9 inches

Rounding to the nearest inch, the diagonal of the canvas measures 27 inches

Sandeep has twice as much as sonia. together they have rs 150. how much does sonia have
Inga [223]

let sonia has the (x)

Sandeep would have twice as much as Sonia so (2x)

together they'd have 150.

so, x+2x=150

solve for X

3x=150

X=150/3

So x=50 is what Sonia has,

and Sandeep would have 2(50) =100
