Answer:
0,-14
Step-by-step explanation:
5(x+7)²=245
divide both sides by 5
(x+7)²=49
Taking the square root of both sides
x+7=±7
Either x+7=7
subtract 7 from both sides
x+7-7=7-7
x=0
or
x+7=-7
subtract 7 from both sides
x+7-7=-7-7
x=-14
Answer:
D. Subtract 9y from both sides of the equation.
Step-by-step explanation:
A. Divide both sides of the equation by 36.
B. Multiply both sides of the equation by 6.
C. Add 9y to both sides of the equation.
D. Subtract 9y from both sides of the equation.
Given:
9y - 6x = 36
To solve for x
Step 1: subtract 9y from both sides
9y - 6x - 9y = 36 - 9y
- 6x = 36 - 9y
Step 2: Divide both sides by -6
- 6x / -6 = (36 - 9y) / - 6
x = (36 - 9y) / - 6
The answer is
x = (36 - 9y) / - 6
Hey, you didn’t provide any picture or further context.
To solve for gradient, do (y2-y1)/(x2-x1)
So what do you think?
A: When you multiply two numbers, their exponents add.
So,
Since 64^1/2 multiplied by itself is 64, then it is the square root of 64.
B: The area is irrational. 7 * √7 is irrational.
The observatory telescope has 22 times the magnifying power compared to the small telescope.
Data;
- small telescope = 150 times
- large telescope = 3300
<h3>Division of Numbers</h3>
To solve this question, we have to divide the large telescope by the small telescope to calculate it's magnifying power.
The magnification of the observatory telescope is 22 times greater or larger than the small telescope.
