1/6+3/7=? What does it equal

2 answers:

25/42 that is my best guess. you find it by finding the smallest common number between 6 and 7 and then multiply the number that makes the bottom become that number with the top one EJ, to get to 42 you would have to multiply 7 * 6 so you will multiply both the 7 and the 3 by 6 and to get 42 with 6 you have to 6 *7 so you will multiply the 6 and the 1 by seven and then just add the top one and tehn add the bottom ones

Find the equation of the line that passes through (1,3) and is perpendicular to y = 1 − 2 x

egoroff_w [7]

Answer:

$y=\displaystyle\frac{1}{2} x+\displaystyle \frac{5}{2}$

Step-by-step explanation:

Hi there!

Linear equations are typically organized in slope-intercept form: $y=mx+b$ where m is the slope and b is the y-intercept.

Perpendicular lines always have slopes that are negative reciprocals (ex. 1/2 and -2, 3/4 and -4/3)

Determine the slope (m):

$y = 1 -2x$

Rearrange into slope-intercept form:

$y = -2x+1$

Now, we can identify clearly that the slope is -2. Because perpendicular lines always have slopes that are negative reciprocals, a perpendicular line would have a slope of $\displaystyle\frac{1}{2}$ . Plug this into $y=mx+b$ :

$y=\displaystyle\frac{1}{2} x+b$

Determine the y-intercept (b):

$y=\displaystyle\frac{1}{2} x+b$

Plug in the given point (1,3) and solve for b:

$3=\displaystyle\frac{1}{2} *1+b\\\\b=\displaystyle \frac{5}{2}$

Therefore, the y-intercept is $\displaystyle \frac{5}{2}$ . Plug this back into $y=\displaystyle\frac{1}{2} x+b$ :

$y=\displaystyle\frac{1}{2} x+\displaystyle \frac{5}{2}$

I hope this helps!

Use the drawing tool(s) to form the correct answer on the provided number line.

miskamm [114]

Answer:

x= 1, x= 4, and x= -3

Step-by-step explanation:

Use the possible combinations of factors of the constant term of the polynomial to find a first root. Try 1, -1, 2, -2, 3, -3, etc.

Notice in particular that x = 1 is a root (makes f(1) = 0):

$f(1)=x^3-2*1^2-11*1+12=1-2-11+12=13-13=0$

So we know that x=1 is a root, and therefore, the binomial (x-1) must divide the original polynomial exactly.

As we perform the division, we find that the remainder of it is zero (perfect division) and the quotient is: $x^2-x-12$

This is now a quadratic expression for which we can find its factor form:

$x^2-x-12=x^2-4x+3x-12=x(x-4)+3(x-4)=(x-4)*(x+3)$

From the factors we just found, we conclude that x intercepts (zeroes) of the original polynomial are those x-values for which each of the factors: (x-1), (x-4) and (x+3) give zero. That is, the values x= 1, x= 4, and x= -3. (these are the roots of the polynomial.

Mark these values on the number line as requested.

Answer:

$466

Step-by-step explanation:

Represent her salary by s. Then the amount spent on rent is s/2.

After spending 168 on her electric and water bills, she had s/2 - 168 dollars left. She spent half of this on her phone bill, leaving her with

s/2 - 168

-------------- dollars.

After buying $57 worth of gas, she had

s/2 - 168

-------------- - 57 dollars left, and this came to $92.

We must now solve for s.

First, multiply all three terms by 2. We get

s/2 - 168 - 2(57) = 2(92), or

s/2 - 168 - 114 = 184

Simplifying this, we get s/2 = 168 + 114 + 184, or s/2 = 466.

She spent half her salary (that is, half of s) on rent. As seen above, this is $466.

Laptop has a listed price of $860.99 before tax. If the sales tax rate is 9.25%, find the total cost of the laptop with sales ta

Tanzania [10]

Answer

The sales tax is determined by computing a percent of the purchase price. To find the sales tax multiply the purchase price by the sales tax rate. Remember to convert the sales tax rate from a percent to a decimal number. Once the sales tax is calculated, it is added to the purchase price.
