Answer:

0 and -1/4

Step-by-step explanation:

First you need to move the -9x to the left-hand side to set the problem to 0.so when you move it, it becomes a positive

36x^2 + 9x = 0

Now factor out the GCF

9x (4x + 1) = 0

Now set up two problems to solve:

9x = 0 divide by 9

x= 0

4x +1 = 0 subtract 1 from both sides

4x = -1 divide by 4

x = -1/4

The answer in the top right. x = 0 or -1/4

1. Obviously 0 is correct, as anything times 0 will always be 0.

2.
36(-.25)^ = 2.25
9(-.25) = 2.25

Answer:

Step-by-step explanation:

x * x = 7x

7 x 7 = 7 x 7

49 = 49

so if x is 7, the equation is true...

Write the equation of the circle with the given graph.

lara [203]

By identifying the radius and the center, we concluded that the equation is something like:

$(x - 2)^2 + (y - 1.5)^2 = 1.8^2$

<h3></h3><h3>How to write the equation of the circle?</h3>

For a circle centered on the point (a, b) with a radius R, the equation is:

$(x - a)^2 + (y - b)^2 = R^2$

So first we need to identify the center, we can see that it is: (2, 1.5)

And the radius is the distance between the center and the edge.

R = 1.8 (measured with a ruler, respecting the notation of the graph).

Then the equation of the circle is something like:

$(x - 2)^2 + (y - 1.5)^2 = 1.8^2$

What is the value of the expression |a + b| + |c| when a = –3, b = 7, and c = –15?

nikdorinn [45]

We know:
$|a|= \left\{\begin{array}{ccc}a&if\ a \ \textgreater \ 0\\0&if\ a=0\\-a&if\ a \ \textless \ 0\end{array}\right\\\\|2|=2\\|0|=0\\|-3|=3$

$|a+b|+|c|$
substitute a = -3; b = 7; c = -15
$|-3+7|+|-15|=|4|+15=4+15=19$

Please help. There is a strong positive linear correlation between the number of rainy days and the number of grapes produced on

irga5000 [103]

A strong positive linear correlation between the number of rainy days and the number of grapes produced on a grape plant, implies that:
The more the rains the more the number of grapes produced per plant. Hence the answer is:
A] Yes. Since the number of rainy days and number of grapes produced are linearly correlated, this means a greater number of rainy days causes the grape plants to produce more.

The sum of two numbers is 54 . the smaller number is 12 less than the larger number. what are the numbers?

Andreas93 [3]

<span>Let x=one number and x+12= the other number. Together the numbers=54. Set up the equation: x+x+12=54; Combine the variables; 2x+12=54; Subtract 12 from both sides of the equation; 2x=42; Divide both sides of the equation by 2; x=21 is one number and 21+12=33 is the other number. Check: 2(21) +12=54; 42+12=54; 54=54.</span>
