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
