Answer:

equation: y = -4x + 7

slope: -4

y-intercept: 7

Step-by-step explanation:

in order to make this equation into slope-intercept form, you have to isolate the y

to do that, you can subtract the 4x on both sides, which will leave y by itself

4x + y = 7

-4x -4x

y = -4x + 7

the slope is -4

and the y-intercept is 7

Answer:

Identify the slope, m. This can be done by calculating the slope between two known points of the line using the slope formula.

Find the y-intercept. This can be done by substituting the slope and the coordinates of a point (x, y) on the line in the slope-intercept formula and then solve for b.

Given f(x) = 15x + 35, what is the domain of f?

ankoles [38]

The answer is [ all real numbers ]

The reason why is because the function as no "undefined" points and it also doesn't have any constraints which means that any number could be used without affecting it.

Best of Luck!

Televisions and monitors come in two common aspect ratios, 4:3 and 16:9 (sometimes

kati45 [8]

Answer:

The dimension of the TV = 11.2 inches × 8.4 inches

Step-by-step explanation:

Let x be the length of the TV

Let y be the width of the TV

x : y = 4:3

$\frac{x}{y} = \frac{4}{3} \\cross-multiplying\\3x = 4y \\x = \frac{4}{3} y- - - - - (1)$

From the figure attached:

using Pythagoras theorem

x² + y² = 42²

where:

$x = \frac{4}{3} y\\(\frac{4}{3}y)^2 + y^2 = 42^2\\\frac{16}{9}y^2 + y^2 = 1764\\ \frac{16y^2}{9} + \frac{y^2}{1} = 1764\\\frac{16y^2 +9y^2}{9}= 1764\\ cross-multiplying\\16y^2 + 9y^2 = 1764\\25y^2 = 1764\\y^2 = \frac{1764}{24}\\y^2 = 70.56\\y = \sqrt{70.56} \\y = 8.4\ inches\\Finding\ x:\\x = \frac{4}{3} y\\x = \frac{4}{3} \times 8.4\\ x = 1.33 \times 8.4\\x = 11.2\ inches\\\therefore\ the\ dimensions\ are\ 11.2\ inches \times 8.4\ inches$
