Virty [35]

Answer:

The width is 10 inches

Step-by-step explanation:

Perimeter = 2(Length + Breadth)

Length(L) = 3B + 5

Perimeter = 70

70 = 2(3B + 5)

70 = 6B + 10

70 - 10 = 6B

60 = 6B

60/6 = B

B = 10 inches

A chef got 7 bags of onions. The red onions came in bags of 8 and the yellow onions came in bags of 3. If the chef got a total o

frutty [35]

Answer:

$\#\text{ of 8-onion bags: }4,\\\#\text{ of 3-onion bags: }3$

Step-by-step explanation:

Let $a$ be the number of bags with 8 onions and let $b$ be the number of bags with 3 onions. We have the following system of equations:

$\begin{cases}a+b=7,\\8a+3b=41\end{cases}$

Subtracting $b$ from both sides of the first equation, we get $a=7-b$ . Substitute this into the second equation:

$8(7-b)+3b=41,\\56-8b+3b=41,\\56-5b=41,\\-5b=-15,\\b=\boxed{3}$

Therefore, the number of 8-onion bags is:

$a=7-b,\\a=7-3,\\a=\boxed{4}$

Thus, the chef got 4 8-onion bags and 3 3-onion bags.

Find the equation of a line that is perpendicular to line g that contains (P, Q). coordinate plane with line g that passes throu

maw [93]

Answer:

$y - Q = - \frac{1}{4}(x - P)$

Step-by-step explanation:

Line g passes through (-2,6) and (-3,2).

The slope of line g is given by:

$\frac{ y_2-y_1}{x_2-x_1}$

Let's substitute the values to get:

$\frac{2 - 6}{ - 3 - - 2}= \frac{ - 4}{ - 1} = 4$

The equation that is perpendicular to line g will have a slope that is the negative reciprocal of 4.

i.e -1/4

If this line passes through (P,Q), then the equation is:

$y - Q = - \frac{1}{4} (x - P)$

The graph of y=1/x is shown below. Draw the graph of its inverse.

lord [1]

Y=1/x solve for x

x=1/y now reverse lables...

y=1/x

Yes that is the same equation you started with. What that means is the the inverse function in this case produces the same exact graph :)
