Peter works as a delivery person for a bike shipping company. The graph shows a linear model for his delivery times on different
aev [14]

Answer/Step-by-step explanation:

✍️The equation of the line in point-slope form:

The equation is given as y - b = m(x - a), where,

(a, b) = a point on the line.

slope (m) = \frac{y_2 - y_1}{x_2 - x_1}

Let's find the slope (m) of the line, housing (3, 21) and (6, 12):

slope (m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{12 - 21}{6 - 3} = \frac{-9}{3} = -3

Substitute a = 3 and b = 21, m = -3 into y - b = m(x - a).

Thus, the point-slope equation would be:

✅y - 21 = -3(x - 3)

✍️The equation of the line in slope-intercept form:

Rewrite y - 21 = -3(x - 3), so that y is made the subject of the formula.

y - 21 = -3x + 9

Add 21 to both sides

y = -3x + 9 + 21

y = -3x + 30

✅The slope-intercept equation of the line is y = -3x + 30

Where,

-3 = how much did his delivery time decrease per day (slope)

30 = how long it initially took Peter to deliver his packages (y-intercept)

A ladder is leaning against the side of a building. The
cupoosta [38]

Answer:

16 ft

Step-by-step explanation:

Based on the situation above, it forms into a right triangle. Therefore we can apply the Pythagorean Theorem. We will use the formula below:

c = √( a² + b²)

In the problem above, the ladder acts as the hypotenuse denoted by c. It has a length of 20 ft. While the base denoted by b is 12 ft. Therefore, we need to solve for a. We will derive the formula above.

c² = a² + b²

a² = c² - b²

a = √( c² - b² )

a = √( 20² - 12² )

a = 16

The unit is in ft.

Correct me if I'm wrong. I hope it helps.

To solve 49^3x = 343^2x+1, write each side of the<br> equation in terms of base<br> DONE
Nostrana [21]

Answer:

no solution

Step-by-step explanation:

49^3x = 343^2x+1

49 = 7^2 and 343 = 7^3

7^2 ^3x  = 7^3 ^2x+1

we know that a^b^c = a^ (b*c)

7^(2 *3x)  = 7^(3 *(2x+1))

7^(6x)  = 7^(6x+3)

The bases are the same so the exponents have to be the same

6x = 6x+3

Subtract 6x from each side

0 =3

This is never true so there is no solution
