The zeros of a function are the values of x that make the function be equal to zero.
When graphing a quadratic equation, the graph is a parabola, and the zeros of the function are the x-intercepts of the graph, which are the points where the graph intersects the x-axis.
So, if the zeros of this function are x = -8 and x = 2, that means the parabola crosses the x-axis at x = -8 and x = 2.
Therefore the correct option is the first one.
-2x^2+-4x+-3x+-6
-2x^2-7x-6
Answer:
We have a right tailed test then the p value would be:
Step-by-step explanation:
Information provided
n=497 represent the random sample of homes selected
X=340 represent the number of homes with one or more lawn
estimated proportion of homes with one or more lawn
is the value that we want to test
z would represent the statistic
represent the p value (variable of interest)
System of hypothesis
We want to check if proportion of homeowners owning lawn mowers in charlotte is higher than 65%m so then the correct hypothesis are .:
Null hypothesis:
Alternative hypothesis:
The statistic is given by:
(1)
Replacing the info given we got:
We have a right tailed test then the p value would be:
Answer:
<em>The solution to the system of equation is (0, 2). The equation has only one solution.</em>
Step-by-step explanation:
Given the system of equations
y= x + 2 .... 1
2y = x + 4 ... 2
Substitute equation 1 into 2;
From 2; 2y = x+4
2(x+2) = x+4
2x+4 = x+4
2x - x = 4-4
x = 0
Substitute x = 0 into 1;
From 1; y = x+2
y = 0+2
y = 2
Hence the solution to the system of equation is (0, 2). The equation has only one solution.

Answer:
1/3
Step-by-step explanation:
so the ratio is 3:6
there are 9 total parts
divide 234 by 9 and you get 26
there are $26 per part
multiply 26 by 3 to get Tom's reward, which is 78
multiply 26 by 6 to get Chuck's reward, which is 156
the fraction of the total reward that Tom gets is 78/234<em> (this is Tom's $ over total)</em>
simplify and get 1/3
