A line that passes through the point (1, –1) and parallel to another line whose slope is 1.

Mars2501 [29]

Parallel lines have same slope so so far the new equation looks like this
$y = 1x + b \\ y = mx + b$
now you plug in you points or coordinates to find b or solve for the y-intercept
$- 1 = 1(1) + b$
$- 1 = 1 + b$
$- 1 = 1 + b \\ - 1 = - 1$
$- 2 = b$
now that you have your b your final solution is
$y = 1x - 2 \: or \: y = x - 2$

The sum of the base and the height of a triangle is 2626 cm. find the dimensions for which the area is a maximum.

Lelu [443]

Let the height of the triangle be $h$ and the base be $b$ .

Given that $h+b=26$ and the area of the triangle is $A=\frac{bh}{2}$ . Or

$A(h)=\frac{(26-h)h}{2}$ .

When the area is maximum, $\frac{dA}{dh} =0$ .

or,

$\frac{d\frac{(26-h)h}{2} }{dh} =0$ .

$\frac{d(26-h)h }{dh} =0$

$2h-26=0$

$h=13$

The dimensions of the triangle with maximum area is

$h=13 cm, b=13 cm$

Find the value of x. do not include the degree symbol in your answer.

hjlf

Answer:

x = 50

Step-by-step explanation:

The chord- chord angle is half the sum of the arcs intercepted by the angle and its vertical angle, that is

$\frac{1}{2}$ (x + 110) = 80 ← multiply both sides by 2 to clear the fraction

x + 110 = 160 ( subtract 110 from both sides )

x = 50

Each pencil costs x cents and each eraser costs y cents. What is the total cost in dollars of 10 pencils and 12 erasers

mamaluj [8]

The total cost is 10x+12y unless there are specific amounts for x and/or y. If there are, simply plug them into the equation.
