Answer:
4.5=4 and 1/2
Step-by-step explanation:
SAS similarity. the angle degree is the same. if you multiply 14 and 8 by a factor of 7 you get 98 and 56 which means the triangle have the same ratio making them similar. because of this ratio it makes the side similar therefore being a SAS similarity because the angle is between the sides.
Step-by-step explanation:
=3.0625/ 1
=30625/10000
(multiply top until the decimal goes. and have to multiply by the same number bottom also, here have multiplied by 10000 both bottom and top)
=6125/ 2000
=49/16 (simplify the both bottom and top)
When the gradient of the slope is negative or positive, the slope is negative or positive respectively.
or if u wanna tell by looking at the straight line graph, then if it makes an acute angle with the x-axis it's positive, if it makes an obtuse angle with x-axis its negative.
the slope is zero when the graph is horizontal
then slope is undefined when eh graph is vertical.
hope this helps
