Answer: the statement “measure of <4 is 105 degrees” is incorrect.
Explanation: This is because since both angles 1 and 3 are vertical, this means they are both 95. This gives us 190 (95x2). Now we subtract this from 360 which gives us 170. Since angles 2 and 4 are vertical, we divide by 2, which gives us 85, not 105.
Hope this helps! :)
Answer:
2^6
Step-by-step explanation:
What I did was multiply 2 by 2 as many times as it took to get to 64 since 2 is a multiplicity of 64
There is no background information on this
Answer:
-y + 63
Step-by-step explanation:
Let's start like by solving the order of operations, and then add our Y's:
7y + 7 + −8y + 56
Adding:
+63 - y
Simplifying:
-y + 63
Thus, our answer is -y + 63
Answer:
second and fourth option
Step-by-step explanation:
the <em>discriminant </em>of a quadratic equation is the easiest way to know how many solutions there will be
(discriminant: b²- 4ac)
{a discriminant of 0 means 1 solution; discriminant < 0 means no real roots, discriminant > 0 means two real roots }
so, we can quickly run b² - 4ac for each equation provided:
(note: ax² + bx + c is the formatting we use to find a, b, and c)
8² - 4(-9)(-8)
64 - 288 = -224
4² - (4)(1)(4)
16 - 16 = 0
-1² - (4)(-10)(-9)
-1 - 360 = -361
-6² - (4)(3)(3)
36 - 36 = 0
So, because the second and fourth options listed have a discriminant of 0, they have 1 real solution
hope this helps!! have a lovely day :)
