Answer: A, -6

Step-by-step explanation: If it is the problem I think it is there should be a chart with the first column labeled x that includes -2, -1, 0, 1, and 2. The second column should be labeled y and includes 8, 2, -4, -10, and -16. You use the slope formula the m=rise/run which is also y2-y1/x2-x1=slope. So now you substitute y2 as 2, y1 as 8, x2 as -1, and x1 as -2. Now you do 2-8/-1- -2, which becomes 2+-8/-1+2. When you add 2 and -8 you get -6 and when you add -1 and 2 you get 1. Now we put them together to get -6/1, which equals -6, as our slope.

When I solved this equation I got x=0.5
qwelly [4]

You might have made an error the first time you solved for x. I got x = -0.5.

When you have your log base 4, the way you cancel that out is by making 4 the base on both sides, so you get 4^(log4) to reduce to 1, and you're left with:

2x + 3 = 4^(1/2) ... Simplify

2x + 3 = 2

2x = -1

x = -1/2

If you plug that back in, everything checks out. Maybe double check your use of logarithm/exponent properties?

A shortage of gold causes the price of gold wire to increase by 140%. If 10 feet of gold wire previously cost $50, what is the n
Marianna [84]
The increase in price is 140% of the original price.
The original price was 100% of the original price since 100% is a whole quantity.
Now the new price is 140% more than it was, so the new price is
100% + 140% of the old price.
100% + 140% = 240%

Now we find 240% of $50.
To find a percent of a number, multiply the percent by the number.

240% of $50 =
= 240% * $50
= 2.4 * $50
= $120

Answer: 10 ft of gold wire now costs $120
Gold wire now costs $12 per foot.

The mean can be found by adding the two numbers and dividing by 2

let the second number be y

(x + y)/2 = 1/2x + 1

solve for y

multiply each side by 2
x + y = 2(1/2x + 1)
distribute
x + y = x + 2
subtract x on both sides
y = 2

ANSWER: the second number is 2

Write an equation of a line that passes through the point (-5,3) and is parallel to the line y = -2x + 5.
zimovet [89]

Answer:

Step-by-step explanation:

y = -2x+5

slope of line is -2.

slope of parallel to line is also -2

point-slope equation for line of slope -2 that passes through (-5,3):

y-3 = -2(x+5)
