Answer: 
Step-by-step explanation:
By the negative exponent rule, you have that:
By the exponents properties, you know that:
You can rewrite 16 and 9 as following:
16=4²
9=3²
Therefore, you can rewrite the left side of the equation has following:
As the base are equal, then:
Solve for x:
Answer:
33
Step-by-step explanation:
Answer:
y = -6
Step-by-step explanation:
Step 1: Define
8x - 9y = -50
x = -13
Step 2: Substitute and solve for <em>y</em>
8(-13) - 9y = -50
-104 - 9y = -50
-9y = 54
y = -6
2y + 12 = -3x
Step-by-step explanation:
Divide y y by 1 1 . Divide 12 12 by 2 2 . Use the slope-intercept form to find the slope and y-intercept. The slope-intercept form is y=mx+b y = m x + b , where m m is the slope and b b is the y-intercept.
Answer:
79.5 feet
Step-by-step explanation:
5.3 per minute can also be written as the ratio 5.3:1. so if we have x:15, we can see that we've multiplied the right side by 15 so we have to do the same to the other side. 15 times 5.3 is 79.5. so thats your answer.
i hope this helps :))
