Jen measured the growth of a sunflower. In week one, it grew 2 1/2 inches. In week two, it grew 2 3/4 Inches. In week three, it grew 3 1/4 Inches. How much did the sunflower grow over all the three weeks?

First find the slope m. slope formula: [tex]\frac{y_{2} - y_{1} }{x_{2} - x_{1} }[/tex]

Let's use (0, -20) for x1 and y1; and (2, 10) for x2 and y2

[tex]\frac{10-(-20)}{2-0}[/tex] = [tex]\frac{30}{2}[/tex] = [tex]15[/tex]

Now find the y-intercept: the point where the graph crosses the y-axis. The y intercept always has an x value of 0. So -20 is the y-intercept

Use the slope formula [tex]y = mx + b[/tex]. Slope=m, y-intercept = b

y = 15x - 20

y is the money in the bank account in dollars

x is the day

Answer:

x = 18

Step-by-step explanation:

1/2x - 7 = 1/3 (x- 12)

Multiply both sides by 3

3 * 1/2x - 3 * 7 = 3 * 1/3 (x - 12)

3/2x - 21 = x - 12

Collect like terms

3/2x - x = 21 - 12

1/2x = 9

Multiply both sides by 2

x = 2 * 9

x = 18

Answer:

x = 18

Answer:

y=-1/3x-6

Step-by-step explanation:

Perpendicular lines have slopes that are negative and reciprocal; if you multiply them together, the result is -1

so, to find the slope of the new line:

3m=-1

divide by 3

m=-1/3

the slope of the new line is -1/3

Slope-intercept form is written as y=mx+b, where m is the slope and b is the y intercept.

Here's our equation so far:

y=-1/3x+b

since the line passes through the point (9,-9), we can use it to solve for b

substitute into the equation:

-9=-1/3(9)+b

-9=-3+b

-6=b

b is -6

here's our equation

y=-1/3x-6

hope this helps! :D

Z in the second blank

Answer:

C

Step-by-step explanation:

Hello There!

x = # of cars and y = # of vans

the total amount of vehicles is 12 so

x + y = 12

each car can hold 4 students and each van can carry 12 students

there are a total amount of 72 students

so 4x + 12y = 72

so from the given information we can conclude that the answer is C

Answer:

18 is 14% of 128.5714

Step-by-step explanation:

it's 77.78

Step-by-step explanation:

14: 18*100 =

(14*100): 18 =

1400: 18 = 77.78

Now we have: 14 is what percent of 18 = 77.78

Question: 14 is what percent of 18?

Percentage solution with steps:

Step 1: We make the assumption that 18 is 100% since it is our output value.

Step 2: We next represent the value we seek with $x$x.

Step 3: From step 1, it follows that $100\%=18$100%=18.

Step 4: In the same vein, $x\%=14$x%=14.

Step 5: This gives us a pair of simple equations:

$100\%=18(1)$100%=18(1).

Step 6: By simply dividing equation 1 by equation 2 and taking note of the fact that both the LHS

(left hand side) of both equations have the same unit (%); we have

$\frac{100\%}{x\%}=\frac{18}{14}$100%x%=1814

Step 7: Taking the inverse (or reciprocal) of both sides yields

$\frac{x\%}{100\%}=\frac{14}{18}$x%100%=1418

$\Rightarrow x=77.78\%$⇒x=77.78%

Therefore, $14$14 is $77.78\%$77.78% of $18$18.

Answer:

2% per year.

Step-by-step explanation:

Solving our equation

r = 960 / ( 12000 × 4 ) = 0.02

r = 0.02

converting r decimal to a percentage

R = 0.02 * 100 = 2%/year

The interest rate required to

accumulate simple interest of $ 960.00

from a principal of $ 12,000.00

over 4 years is 2% per year.

Answer:

[tex](x,y) = (-1,0)[/tex]

Step-by-step explanation:

Given

[tex](x+1)^2 = -8(y-2)[/tex]

Required

The coordinates of the focus

First, write the expression in form of: [tex]y=a(x-h)^2+k[/tex]

[tex](x+1)^2 = -8(y-2)[/tex]

[tex](x+1)^2 = -8y + 16[/tex]

[tex]-8y + 16 = (x+1)^2[/tex]

Subtract 16 from both sides

[tex]-8y = (x+1)^2 - 16[/tex]

Divide through by -8

[tex]y = -\frac{1}{8}(x+1)^2 - \frac{16}{-8}[/tex]

[tex]y = -\frac{1}{8}(x+1)^2 +2[/tex]

In this case:

[tex]a = -\frac{1}{8}[/tex]

[tex]-h = 1[/tex]         [tex]h = -1[/tex]

[tex]k = 2[/tex]

The focus of the parabola is:

[tex](x,y) = (h,k + \frac{1}{4a})[/tex]

This gives:

[tex](x,y) = (-1,2 + \frac{1}{4*-\frac{1}{8}})[/tex]

[tex](x,y) = (-1,2 + \frac{1}{-\frac{1}{2}})[/tex]

[tex](x,y) = (-1,2 -2)[/tex]

[tex](x,y) = (-1,0)[/tex]

Answer:

A

Step-by-step explanation:

Given

[tex]\frac{1}{3}[/tex] x - 8 = - 12 ( multiply through by 3 to clear the fraction )

x - 24 = - 36 ( add 24 to both sides )

x = - 12 → A

Answer:
