What are the x and y intercepts of y=x^2+3x-10 (show all steps please)
Phoenix [80]

Answer:

X-int: (2,0) , (-5,0)

Y-int: (0,-10)

Step-by-step explanation:

To solve for the x-int, set y to 0.

0= x^2 + 3x - 10

0= (x-2)(x+5)

x= 2, and -5

To solve for the y-int, set x to 0.

y= (0)^2 + 3(0) - 10

y= -10

2. A palindrome is a number or a word that is the same in the two directions: left to right and vice
a_sh-v [17]

Answer:

90 between 1000 and 9999

Step-by-step explanation:

The first digit cannot be 0. It can be nine other digits.

The second digit can be anything between 0 and 9.

To be palindromic the 2nd and 3rd digits must be the same.

And in addition, the 1st and 4 numbers must be the same.

So the answer is 9 * 10 = 90. That does seem too small, but try making a palindrome with the restrictions I have outlined. None of the examples you have given beginning with 8 are palindromic.

8118 is palindromic

8998 is also palindromic

9009 is palindromic

2002 is palindromic

There are only 90 of them.

Please HELP me. I've been trying to solve this question for an hour but I didn't find any answer.
Marta_Voda [28]
Volume of a cylinder is formulated as: π·r²h
Surface area of a cylinder is formulated as: 2π·rh + 2π·r²

So, for a:
Volume = π·5²·12 = π·25·12 = 300π
Surface area = 2π·5·12 + 2π·5² = 120π + 50π = 170π

And it's essentially the same process for the other questions.

Which equation represents a line which is parallel to the line 7x - y = 4?
koban [17]

Answer:

Step-by-step explanation: step : Place the given line’s equation in slope- intercept form y = mx + b. A line parallel to this line will have the same slope.

7x - y = 4. Yields y = 7 x - 4. Therefore y = 7x - 5 is the correct answer.
