Convert to slope-intercept form, y = mx + b.

12 = 4x - 6y

Subtract 4x to both sides:

12 - 4x = -6y

Divide -6 to both sides:

y = 2/3y - 2

Now its in slope-intercept form, y = mx + b, where 'm' is the slope.

So the slope is 2/3.

Solve for x in the equation x squared minus 10 x + 25 = 35.
atroni [7]

Answer:

x = 5 ± \sqrt{35}

Step-by-step explanation:

Given

x² - 10x + 25 = 35 ( subtract 25 from both sides )

x² - 10x = 10

Using the method of completing the square

add ( half the coefficient of the x- term )² to both sides

x² + 2(- 5)x + 25 = 10 + 25

(x - 5)² = 35 ( take the square root of both sides )

x - 5 = ± \sqrt{35} ( add 5 to both sides )

x = 5 ± \sqrt{35}

That is the second option on list

The length of a rectangular mailing label is
trasher [3.6K]
P = 2(L + W)
P = 22
L = 2W - 4

22 = 2(2W - 4 + W)
22 = 2(3W - 4)
22 = 6W - 8
22 + 8 = 6W
30 = 6W
30/6 = W
5 = W.....width is 5 cm

L = 2W - 4
L = 2(5) - 4
L = 10 - 4
L = 6....length is 6 cm

alfred deposited $893.78 in a savings account that earns 2.2% simple interest. What is alfreds account balance after seven years
ASHA 777 [7]
Hello!  The formula for finding simple interest is prt. That means multiply the principal (initial amount) by the rate (percentage) by time (months or years). The principal is $893.78 and the interest rate is 2.2%. 893.78 * 2.2% (0.022) is 19.66316. Do not delete that number. The time is 7 years. Now multiply that number by 7 in order to get 137.64212 or $137.64 when rounded to the nearest whole hundredth.  Now, let's add both numbers. 893.78 + 137.64 is 1,031.42. There. Alfred's balance after seven years is $1,031.42.

Find the slope of the line between (1,5) and (3,9)
8_murik_8 [283]

Answer:


Step-by-step explanation: Use the two points that are given to you and substitute them into the slope formula to find the answer.

m=<u><em>y2-y1/x2-x1</em></u>

m=9-5/3-1

m=4/2

Simplify the answer.

m=4/2

m=2/1

Final answer is 2.

The slope is positive meaning it is ascending (going up).
