Anastaziya [24]

Answer:

It sold 43.57 iPhones for the same quarter in the previous year.

Step-by-step explanation:

It sold 61.0 million iPhone, which is an increase of 40% over the value of the previous year x.

This can be interpreted as:

61 million is 140% = 1.4 of the previous year amount, that is, x. So

$1.4x = 61$

$x = \frac{61}{1.4}$

$x = 43.57$

It sold 43.57 iPhones for the same quarter in the previous year.

What is the equation in slope-intercept form of a line that passes through the points (5,3) (4,-3)

Darya [45]

Answer:

y=6x-27

Step-by-step explanation:

To find the slope of a line given 2 points; use this equation.

$\frac{y_2-y_1}{x_2-x_1} = \frac{rise}{run}$

(5,3) (4,-3)

$x_1 y_1$ $\\x_2 y_2\\\\$

$\frac{3 - (-3)}{4-5} =\frac{-6}{-1} = 6$

slope = 6

as for y-intercept use this method in the attachment

Find x and y 30 points

Vika [28.1K]

Since the two triangles are similar

$\frac{5 + x}{5} = \frac{7 + y}{7} = \frac{10}{8} \\ \implies \frac{5 + x}{5} = \frac{10}{8} \\ \implies x = \frac{50}{8} - 5 = \frac{50 - 40}{8} = \frac{10}{8} = \frac{5}{4} \\ \therefore x = \frac{5}{4}$

Also,

$\\ \frac{7 + y}{7} = \frac{10}{8} \\ \implies y = \frac{70}{8} - 7 = \frac{70 - 56}{8} \\ \therefore y = \frac{14}{8} = \frac{7}{4}$
