Answer:

b = -6.307 or -11.693

Step-by-step explanation:

b^{2} +9b +13\\

This can't be factored so you need to use the quadratic formula which is

-b ± \frac{\sqrt{b^{2} -4ac}}{2a}

Plugging the numbers from the equation in, it's

-(9) ± \frac{\sqrt{(9)^{2}-4(1)(13) } }{2(1)}

This simplifies down to b = -6.307 or -11.693.

These are both real solutions.

A 2/3=8/2. B. 4/9=8/9 c 3/4&gt;9/10 d 2/4&gt;2/3 which comparison is true
vladimir2022 [97]

The given comparisons are not true in all of the options provided.

<u>Step-by-step explanation:</u>

The given comparisons are in the form of fractions.

Check each of the given options one by one based on the relation given for the comparison.

Option a) is 2/3 = 8/2. Here, you have to check that the given fractions are equal or not. If both the values are equal, then the comparison is true. If they are not equal, then the comparison is false.

By dividing 2 by 3, we get a value of 0.666

By dividing 8 by 2, we get a value of 4.

Therefore, 0.666 ≠ 4. The comparison is false.

Option b) is 4/9 = 8/9. Here, you have to check that the given fractions are equal or not.

Look into the given comparison, the fractions have same denominator of 9.

In such cases, if the denominator is same and the numerator value is different, then they are not equal.

Therefore, 4/9 ≠ 8/9. The comparison is false.

Option c) is 3/4 > 9/10. Here, you have to check whether 3/4 is greater than 9/10.

By dividing 3 by 4, we get a value of 0.75

By dividing 9 by 10, we get a value of 0.9

Therefore, 0.75 is not greater than 0.9. The comparison is false.

Option d) is 2/4 > 2/3. Here, you have to check whether 2/4 is greater than 2/3.

By dividing 2 by 4, we get a value of 0.5

By dividing 2 by 3, we get a value of 0.666

Therefore, 0.5 is not greater than 0.666. The comparison is false.

Raphael graphed the functions g(x)=x+2 and f(x)=x−1. How many units below the y-intercept of g(x) is the y-intercept of f(x)? A
jasenka [17]

Answer:

3 units below the y-intercept of g(x) is the y-intercept of f(x)

Step-by-step explanation:

g(x)=x+2 and f(x)=x-1

In f(x)= mx+b the y intercept is b

In g(x)=x+2, the y intercept value is 2

In f(x)=x-1, the y intercept value is -1

the difference in y intercept is +2-(-1)=+3

3 units below the y-intercept of g(x) is the y-intercept of f(x)
