Log7 (x+3) - log7 (x-3) = 1
log7 [(x+3) / (x-3)] = 1
raise both sides to power of 7
(x+3) / (x-3) = 7
7x – 21 = x + 3
6x = 24
x = 4

A rectangular baking pan is 12 inches long, 6 inches wide, and 2.5 inches tall. If 1 cubic inch of cake mix is approximately 0.5
ahrayia [7]

Answer:

Amount of cake mix baking pan can hold is 99 ounces

Step-by-step explanation:

Here we have the size of the baking pan is given by the following relation

Volume of baking pan = Length × Width × Height

Volume of baking pan = 12 in. × 6 in. × 2.5 in. = 180 in.³

Mass of 1 cubic inch of cake mix = 0.55 ounces, therefore, the mass of cake mix that the 180 in.³ baking pan can hold is found as follows;

Amount of cake mix baking pan can hold = Volume of baking pan × Mass per cubic inch of cake mix

Amount of cake mix baking pan can hold = 180 in.³ × 0.55 ounce/in.³ = 99 ounces.

Find the slope <br> (-19,-6) (15,16)
Alex Ar [27]

Answer:

11/17

Step-by-step explanation:

slope between two points: slope = (y2 - y1) / (x2 - x1)

(x1, y1) = (-19, -6), (x2, y2) = (15, 16)

m = (16 - ( - 6)) / (15 - ( - 19))

refine

m = 11/17

sorry it is hard to follow... i am on my phone rn :/

Write two solutions for the following equation 2x+3y=24.
SVETLANKA909090 [29]

Answer: (12, 0) and (0, 8)

Step-by-step explanation:

This equation is in standard form. We can sub in a number for x to solve for y and vice versa.

Let's sub in 0 for x.

2x+3y=24\\2(0)+3y=24\\3y=24\\\frac{3y}{3} =\frac{24}{3} \\y=8

When x is 0 y is 8 giving us the coordinate (0, 8).

Now lets sub in 0 for y

2x+3(0)=24\\2x=24\\\frac{2x}{2} =\frac{24}{2} \\x=12

When y is 0 x is 12 giving us the coordinate (12, 0)
