Answer:

<em>b =  \frac{13}{12}</em>

<em>Solution</em><em>,</em>

<em>b -  \frac{7}{4}  =  \frac{ - 2}{3}  \\ or \:  \frac{b \times 4 - 7}{4}  =  \frac{ - 2}{ 3 }  \\ or \:  \frac{4b - 7}{4}  =  \frac{ - 2}{3}  \\ or \: 3(4b - 7) =  - 2  \times 4 \\ or \: 12b - 21 =  - 8 \\ or \: 12b =  - 8 + 21 \\ or \: 12b = 13 \\  \: b =  \frac{13}{12}</em>

Annabel is comparing the distances that two electric cars can travel after the battery is fully charged. Car A (miles) Car B (mi
Maslowich

Answer:

Car B can travel further than Car A after the battery is fully charged.

D. Car B because the measures of variability are smaller for Car B than for Car A.

Step-by-step explanation:

Car B can travel further than Car A after the battery is fully charged because Car A has lesser mean and median than Car B.

Median divides the data into two halves. A smaller median means that there is lesser mileage of Car A than Car B.

There are two measures.

Measure of center tells us how much near or far the data is spread from the center.

The mean , median and mode are the measures of center.

Car A has less mean , median telling us that it traveled less.

Measure of Variability tells us how data changes with a single value.

Smaller MAD means the data is denser at the mean. Car B has lesser MAD.

Smaller IQR tells us that data is closer to the middle of the data.

Car B has smaller IQR .

So car B traveled consistently as it has smaller IQR and MAD

D. Car B because the measures of variability are smaller for Car B than for Car A.

(2x2 + 5x - 7) + ( 3 - 4x2 + 6x)
velikii [3]

\qquad\qquad\huge\underline{{\sf Answer}}♨

Here's the solution :

\qquad \sf  \dashrightarrow \:(2 {x}^{2}  + 5x - 7) + (3 - 4 {x}^{2}  + 6x)

\qquad \sf  \dashrightarrow \: 2{x}^{2}  + 5x   - 7 + 3 - 4 {x}^{2}  + 6x

\qquad \sf  \dashrightarrow \:2 {x}^{2}  - 4 {x}^{2}  + 5x + 6x - 7 + 3

\qquad \sf  \dashrightarrow \: - 2 {x}^{2}  + 11x - 4

Complete the table and graph the function.
EastWind [94]

Answer:

X Y

-5 7

-2 1

-1 -1

2 -7

Step-by-step explanation:

If x = -5, then:

y = -3 -2(-5)

y = -3 + 10

y = 7

If x = -2, then:

y = - 3 -2(-2)

y = -3 + 4

y = 1

If x= -1, then:

y = -3 -2(-1)

y = - 3 + 2

y = -1

If x=2, then:

y = -3 -2(2)

y = -3 -4

y = -7
