The equation to use is
y = mx + c

The first thing you need to know is the gradient represented by the m

Do you know how to find the gradient

Answer:

y = -3x² - 3x + 6

Step-by-step explanation:

main formula: r×(x² - (a + b)x + ab) = y

r×(x² - (-2 + 1)x -2×1) =y

r×(x² +x -2) = y

by using the point (0,6) →

r×(0² + 0 -2) = 6

r×-2 = 6

r= -3

so

y= -3x² -3x +6

Literal Equations: Solve for p:<br> 5(4x + p)=w
frosja888 [35]

Answer:

Step-by-step explanation:

Simplifying

5(4x + p) = w

Reorder the terms:

5(p + 4x) = w

(p * 5 + 4x * 5) = w

(5p + 20x) = w

Solving

5p + 20x = w

Solving for variable 'p'.

Move all terms containing p to the left, all other terms to the right.

Add '-20x' to each side of the equation.

5p + 20x + -20x = w + -20x

Combine like terms: 20x + -20x = 0

5p + 0 = w + -20x

5p = w + -20x

Divide each side by '5'.

p = 0.2w + -4x

Simplifying

p = 0.2w + -4x

Please help me with these geometry questions.
sashaice [31]

Answer:

1)2(lb+bh+hl)

=2(17*12+12*8+8*17)

=2(204+96+136)

=2*436

=872 in^2

2)2*pi*r(r+h)

=2*3.14*14(14+29)

=6.28*14(43)

=6.28*14*43

=3780.56 mm^2

3)A=11*4.3+3*6 +3*8+11*3(Area of each plane figure -triangle and rectangle)

=47.3+18+24+33

=122.3cm^3

4)h*(sum of II sides)+14*8+19*8+14*8+25(Area of plane surface-trapezium,rectangle,square)

=12.1(19+5)+112+152+112+25

=12.1*24+401

=290.4+401

=691.4ft^2

Calculate the mean. 4, 5, 7, 7, 9, 12, 15, 20
Semmy [17]

Answer:

Mean: 9.875

Median: 8

Mode: 7

Minimum: 4

Maximum: 20

Range: 16

Size: 8

Sum: 79

Step-by-step explanation:

How to find the mean?

1. Count the number N of data points in your data set.

2. Sum up all of the data points in your data set (add them all together).

3. Average = Mean = Sum/N.

How to find the median ?

The median is the numeric value separating the upper half of a sample data set from the lower half. The median of a data set can be found by arranging all the values from lowest to highest value and picking the one in the middle. If there is an odd number of data values then the median will be the value in the middle. If there is an even number of data values the median is the mean of the two data values in the middle.

For the data set 1, 1, 2, 5, 6, 6, 9 the median is 5.

For the data set 1, 1, 2, 6, 6, 9 the median is 4. It is the mean of 2 and 6 or, (2+6)/2 = 4.

How to find the mode

Mode is the value or values in the data set that occur most frequently.  

For the data set 1, 1, 2, 5, 6, 6, 9 the mode is 1 and also 6.

Hope this helps you! :D

I believe it is

  • 5x+3 = 4x

Adding -4x - 3 to both sides

  • 5x +3 - 4x - 3 = 4x - 4x - 3

Simplifying

  • x = - 3

Answer is - 3
