280 I’m pretty sure. Hope I help :)
Answer:
m=12
Explanation:
Given any quadratic function, y=ax²+bx+c.
We can determine the nature of the roots of such quadratic function by examining the discriminant, D where:
• If D>0, the roots are real and unequal.
,
• If D=0, the roots are real and equal.
,
• If D<0, the roots are complex.
In our given equation:
For the function to have exactly one zero, the value of D=0.
The value of m for which the function will have one zero is 12.
Answer:
For the extra credit question just plant the dotss and if its a square then do what it sais
Step-by-step explanation:
The decimal equivalent is -4.666....
In order to find this, we need to start by just taking the whole number for itself.
-4.
Now we have to handle the fraction version. In order to do that, we need to do the division and turn into a decimal.
2/3 = .666...
Now we simply put them together and get our answer.
-4.666...
HELLO EVERYONE,
TO FIND Y:
We know
a straight line makes an angle of 180
so,
180 = 119-y
180-119 = y
therefore y is
y = 59 degrees
TO FIND X:
We know,
all angles of a quadrilateral make a sum of 360,
so,
A+B+C+D = 360
HERE,
A = 131
B = 56
C = Y = 59
D = X
131 +56+59+X = 360
360 - 246 = X
X = 114 Degrees
Please do mark me the branliest if it helpful for you. Thanks.
