This is easy since you are already given the binomials. Just multiply them together.
(3x + 3)(3x + 3)
9x^2 + 9x + 9x + 9
9x^2 + 18x + 9.
The coefficient of term b is 18, so B = 18

Kaya is saving money at a rate of $30 per month. Edgardo is saving money at a rate of $35 per month. They both started saving at

ladessa [460]

Let Kaya's savings be 30x and Edgardo's savings be 35x If they both started saving at the same time: f(x)=30x f(x)=35x Now, sub in values for x in to the function starting with 0. Subtract y2-y1 and x2-x1 for both functions. For slope: m=y2-y1/x2-x1 so your result will be m=30/1=30 for f(x) = 30x and m=35/1=35 for f(x) = 35x so the slopes are m=30 and m=35 respectively!

Draw 8 lines that are between 1 inch and 3 inches long. Measure each line to the nearest fourth inch, and make a line plot.

IRISSAK [1]

The length of the line is the difference between the endpoints of the line

The length of each line to the nearest fourth inch is 0.25 inch

<h3>How to measure the length of each line</h3>

The length of the horizontal line is given as:

Length = 2 inches

This is calculated as:

Length = 3 inches - 1 inch

Length = 2 inches

8 lines are to be drawn between the 1 inch and 3 inches point.

So, the length (l) of each line is:

$l = \frac{2\ inches}{8}$

Simplify the fraction

$l = \frac{1\ inches}{4}$

Divide

$l = 0.25\ inch$

Hence, the length of each line to the nearest fourth inch is 0.25 inch

1.29 * 5% = 1.29 * 0.05 = 0.0645

0.0645 rounds down to 0.06

1.29 + 0.06 = 1.35

If the discriminant is positive how many solutions are there

ddd [48]

Answer:

$b^2-4ac>0$ yields 2 real roots

Step-by-step explanation:

To find the number of real roots for a quadratic, we apply the discriminate. The discriminate is the inside portion of the square root from the quadratic formula.

• $b^2-4ac>0$ yields 2 real roots

• $b^2-4ac=0$ yields 1 real root

• [tx]b^2-4ac<0[/tex] yields no real roots

Example:

$4x^2-7x+2=0$ where a=4, b=-7, and c=2

$b^2-4ac=(-7)^2-4(4)(2)=49-32=17$ .

It has 2 real roots
