Answer:1,1/2

Step-by-step explanation: First, we got to make an common denomanator, which is 24. 2 1/4 would be 2 6/24, and 3/6 would be 12/24. then, we use 2,6/24 and subtract it by 12/24, which is 1, 18/24, simplified to 1,1/2

B. y = 1

Step-by-step explanation:

Answer:

the asymptote of the graph y = 1

Step-by-step explanation:

The asymptote of the graph y = 1 (Horizontal asymptote)

As you can see a line that a graph is approạching to as it heads towards infinity but it does not intersect.

Moreover, the value of y is decreasing over its domain. as you can see in the graph.

. Use the quadratic formula to solve each quadratic real equation. Round

Liono4ka [1.6K]

Answer:

A. No real solution

B. 5 and -1.5

C. 5.5

Step-by-step explanation:

The quadratic formula is:

$\begin{array}{*{20}c} {\frac{{ - b \pm \sqrt {b^2 - 4ac} }}{{2a}}} \end{array}$ , with a being the x² term, b being the x term, and c being the constant.

Let's solve for a.

$\begin{array}{*{20}c} {\frac{{ 5 \pm \sqrt {5^2 - 4\cdot1\cdot11} }}{{2\cdot1}}} \end{array}$

$\begin{array}{*{20}c} {\frac{{ 5 \pm \sqrt {25 - 44} }}{{2}}} \end{array}$

$\begin{array}{*{20}c} {\frac{{ 5 \pm \sqrt {-19} }}{{2}}} \end{array}$

We can't take the square root of a negative number, so A has no real solution.

Let's do B now.

$\begin{array}{*{20}c} {\frac{{ 7 \pm \sqrt {7^2 - 4\cdot-2\cdot15} }}{{2\cdot-2}}} \end{array}$

$\begin{array}{*{20}c} {\frac{{ 7 \pm \sqrt {49 + 120} }}{{-4}}} \end{array}$

$\begin{array}{*{20}c} {\frac{{ 7 \pm \sqrt {169} }}{{-4}}} \end{array}$

$\begin{array}{*{20}c} {\frac{{ 7 \pm 13 }}{{-4}}} \end{array}$

$\frac{7+13}{4} = 5\\\frac{7-13}{4}=-1.5$

So B has two solutions of 5 and -1.5.

Now to C!

$\begin{array}{*{20}c} {\frac{{ -(-44) \pm \sqrt {-44^2 - 4\cdot4\cdot121} }}{{2\cdot4}}} \end{array}$

$\begin{array}{*{20}c} {\frac{{ 44 \pm \sqrt {1936 - 1936} }}{{8}}} \end{array}$

$\begin{array}{*{20}c} {\frac{{ 44 \pm 0}}{{8}}} \end{array}$

$\frac{44}{8} = 5.5$

So c has one solution: 5.5

Hope this helped (and I'm sorry I'm late!)

78 children attended a trip to Six Flags. 60 of them were boys. Find the ratio of the number of boys to girls, and express the n

cupoosta [38]

First we need to find out how many girls there were
Subtract the number of boys from the total
78 - 60 = 18 girls
Boys : Girls
60 : 18
The GCF of all these numbers is 6, therefore we divide both sides by 6 to get the simplified ratio
60/6 = 10
18/6 = 3
10:3
