How do you solve these?

Vinil7 [7]

For the first one, the answer is -1 1/5

for the second one, the answer is 2.75

for the third one and fourth one,
To divide fractions take the reciprocal (invert the fraction) of the divisor and multiply the dividend. This is the quickest technique for dividing fractions. The top and bottom are being multiplied by the same number and, since that number is the reciprocal of the bottom part, the bottom becomes one

Does the rule y = 2 · x + 4 represent a linear or an exponential function? Explain.

Natali5045456 [20]

<span>B.
Linear function; the independent variable x is not an exponent.

But for me, answer is:
</span>
Linear function; <span>the function is in the form y = mx + b, where m = slope, b = y-intercept, and x is a real number.

Describe the sample space for this problem: 1200 students at a certain school, all with equal probability of being selected on a random draw.

Which outcome (or outcomes) of the sample space compose the event?

Sophie wins the bike. The chances that that will happen are 1/1200, or 0.00083...

Write an equation in Slope-Intercept Form using the table below.

Veseljchak [2.6K]

Answer:

y = x + 46

Step-by-step explanation:

When writing an equation of a line, keep in mind that you always need the following information in order to determine the linear equation in slope-intercept form, y = mx + b:

1. 2 sets of ordered pairs (x, y)

2. Slope (m)

3. Y-intercept (b)

First, choose two pairs of coordinates to use for solving the slope of the line:

Let (x1, y1) = (0, 46)

(x2, y2) = (1, 47)

User the following formula for slope

$m = \frac{y2 - y1}{x2 - x1}$

Plug in the values of the coordinates into the formula: $m = \frac{y2 - y1}{x2 - x1} = \frac{47 - 46}{1 - 0} = \frac{1}{1} = 1$

Therefore, the slope (m) = 1.

Next, we need the y-intercept, (b). The y-intercept is the y-coordinate of the point where the graph of the linear equation crosses the y-axis. The y-intercept is also the value of y when x = 0. The y-coordinate of the point (0, 46) is the y-intercept. Therefore, b = 46.

Given the slope, m = 1, and y-intercept, b = 46, the linear equation in slope-intercept form is:

y = x + 46
