The answer is C, 3ab

ab is the same as a times b, and then 3ab is just multiplying the product of ab by 3

1.
A graph of linear function is a straight line.
Linear function in a slope-intercept form: y = mx + b

Answer: Equation 3: y = 12x + 17.

2.
x|-1 | 0 | 1 | ? |
y| 4 | 7 |10| ? |

a slope: $m=\dfrac{y_2-y_1}{x_2-x_1}$

We choose:
$(-1; 4)\to x_1=-1\ and\ y_1=4\\(0;\ 7)\to x_2=0\ and\ y_2=7$

subtitute:

$m=\dfrac{7-4}{0-(-1)}=\dfrac{3}{1}=3$

a slope-intercept form: $y-y_1=m(x-x_1)$

subtitute:

$y-4=3(x-(-1))\\\\y-4=3(x+1)\\\\y-4=3x+3\ \ \ \ |add\ 4\ to\ both\ sides\\\\y=3x+7\ (*)$

subtitute x = 2 to the equation (*):

$y=3\cdot2+7=6+7=13$

Answer: (2, 13)

3.
(-2; 7), (-5; 4)

the slope: $m=\dfrac{4-7}{-5-(-2)}=\dfrac{-3}{-5+2}=\dfrac{-3}{-3}=1$

$y-7=1(x-(-2))\to y-7=x+2\ \ \ \ |add\ 7\ to\ both\ sides\\y=x+9$

check other:

$(-8;\ 1)\to L=1;\ R=-8+9=1;\ L=R-correct\\(-11;-2)\to L=-2;\ R=-11+9=-2;\ L=R-correct$

The conclusion: It's a linear function

Answer: It is a linear function because there is a constant rate of change in both the input and output values.

4.
y = 3x + 5 /look at the picture/

Answer: It is a linear function because its graph contains the points (0, 5), (1, 8), (2, 11), which are on a straight line.

check:
$(0; 5)\to L=5; R=3\cdot0+5=5;\ L=R-correct\\(1;\ 8)\to L=8;\ R=3\cdot1+5=8;\ L=R-correct\\(2;\ 11)\to L=11;\ R=3\cdot2+5=11;\ L=R-correct$

Daisy purchases 10,000 tennis balls for $4200 she uses her credit card which has an interest rate of 14% if she makes a monthly

zepelin [54]

Answer:

25 months

Step-by-step explanation:

We can use the amortization formula to solve for t.

That formula tells you the monthly payment as a function of interest rate (r=.14), compounding periods per year (n=12), principal borrowed (P=4200), and number of years (t). Using the given values, we have ...

200 = 4200(r/n)/(1 -(1 +r/n)^(-nt))

1 -(1 +r/n)^(-nt) = 4200(r/n)/200

1 -21r/n = (1 +r/n)^(-nt)

log(1 -21r/n) = -nt·log(1 +r/n)

-log(1 -21r/n)/log(1 +r/n) = nt . . . . . . the number of months we want

-log(1 -21(0.14)/12)/log(1 +0.14/12) = nt = 24.23

It will take Daisy about 25 months to pay of her credit card.

Braydon is at the 10-mile Marker at the park to run. He can run at a pace of 3 miles per hour. Lauren is at the 12-mile marker a

madreJ [45]

it will take 1.33 hours for Braydon and Lauren to get to the same mile marker on the path in the park .

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

Here we have , Braydon can run at 3 miles per hour , he's initially at 10 mile marker . Lauren is at the 12-mile marker at the park, She is walking at a pace of 1.5 miles per hour. We need to find How long will it take for Braydon and Lauren to get to the same mile marker on the path in the park .Let's find out:

Let after time t they meet each other so , Braydon can run at 3 miles per hour , he's initially at 10 mile marker . Distance traveled is given by :

⇒ $3t+10$
