Answer:
a
Step-by-step explanation:
it is really obvious
Answer:
x is infinite
Step-by-step explanation:
-6x+7=2x+10-8x-3
reduce:
-6x+7=7-6x
7-6x = 7-6x
x = x
x is infinite
Answer:
b. y=-2x+3
Step-by-step explanation:
find slope by getting any 2 points form the graph
(0,3) (1,1)
m = (y2-y1) / (x2-x1)
m = (1-3) / (1-0) = -2 it means by moving one unit right you need to move 2 unit down
note that it does not matter which points you chose to be second or first
then use slope point equation again it does not matter which point from the slope you use
y - y1 = m ( x - x1 )
y - 3 = -2 ( x - 0)
y = -2x +3
To determine the lengths of the sides from shortest to longest, you need to calculate the corresponding angles. The higher angles will correspond to longer sides.
To find the angles, you have to solve for x. You’re already given that angle A is 76. To find the others, you know that angle C is 180-(16x+16) since it’s supplemental to the exterior angle. Then, you know the sum of the angles of the entire triangle is 180, so add up A, B, and C
A+B+C=180
76+6x+(180-16x-16)=180
240-10x=180
-10x=-60
x=6
So to find angle B, you use 6x or 6(6)=36.
To find angle C, you use 180-(16x-16) or 180-16(6)-16=68
So now match up the angles with their corresponding sides to find the length from shortest to longest.
Angle A (76) corresponds with BC
Angle B (36) corresponds with AC
Angle C (68) corresponds with AB
Again, the higher the degree, the longer the corresponding side, so AC is shortest, AB is next, and BC is the longest.
Answer:
let
i= simple interest
p= principal
t= time
r=rate
data given
p=$720
r=4.25%
t= 3months
i=?
from the formula
i=prt
i=$720×(4.25/100)×3
i=$720×0.0425×3
i=$91.8
therefore simple interest for 3 months is $91.8
