Ivenika [448]

Answer:

Y= 40

Step-by-step explanation:

I know the y equals 40 because I used

a {}^{2}  + b {}^{2}  = c {}^{2}

But for z and x I got stuck, so I hope I helped you a little to move forward with this problem.

(2, -4), (x, y) , A , and B all lie on the line. Find an equation relating x and y.​
frutty [35]

Answer:

An equation relating x and y is:

y = 3/4x - 5.5

Step-by-step explanation:

The slope-intercept form of the line equation

y = mx+b

where

  • m is the slope
  • b is the y-intercept

Given the points

(2, -4), (x, y), A(6, -1), and B(10, 2)

Taking any two points let say A(6, -1), and B(10, 2) to determine the slope

\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}

\left(x_1,\:y_1\right)=\left(6,\:-1\right),\:\left(x_2,\:y_2\right)=\left(10,\:2\right)

m=\frac{2-\left(-1\right)}{10-6}

Refine

m=\frac{3}{4}

We know that the value of the y-intercept can be determined by setting x = 0, and determining the corresponding value of y.

From the graph, it is clear

at x = 0, y = -5.5

Thus, the y-intercept b = -5.5

Thus, substituting b = -5.5 and m = 3/4 in the slope-intercept form of the line equation

y = mx+b

y = 3/4x + (-5.5)

y = 3/4x - 5.5

Therefore, an equation relating x and y is:

y = 3/4x - 5.5

There are 70 students in the school band. 40% of them are sixth graders, 20% are seventh graders, and the rest are eighth grader
nirvana33 [79]
The answer is 10% if There is 40% six graders and 20% seventh graders then you need 10% more to make 100% so it’s 10% eighth graders

3liters of juice to the ratio 5:3:4
Radda [10]

Step-by-step explanation:

Let 3 litres of juice be divided into 5x, 3x and 4x parts.

\therefore \: 5x + 3x + 4x = 3 \: litres \\  \therefore \: 12x = 3000 \: ml\\ \therefore \: x =  \frac{3000}{12}  \\ \therefore \: x =  250 \: ml \\  \therefore \: \\  5x = 5 \times 250 = 1250 \: m = 1.25 \: l \\ 3x = 3\times 250 = 750 \: ml  = 0.75 \: l\\ 4x = 4 \times 250 = 1000 \: ml  = 1 \: l\\
