3.932 × 10^5
First you want to count how many zeros are in there 2 ok then count the 932 because the 3 hundred thousand is going to stay as a regular digit then when you have a scientific notation you need it to be a power of 10 so ten is always going to be the coefficient for the decimal basically.
5x + 4x + 1
= 9x + 1
u just need to simplify the answer
Answer:
x = 113
Step-by-step explanation:
( 5x + 685 ) + ( 12x - 106 ) = 2500 ( 685 - 106 = 579)
17x + 579 = 2500
17x = 2500 - 579
17x = 1921
x = 1921 / 17
x = 113
So hmm check the picture below
the height or altitude is CD
and the base is AB
how long are those? well
Y=mx+b m=slope
so the equation that you want to find will have 1 for x and 4 for y and will have the same slope (-4) as y=-4x-5 but different 'b' value so
y=-4x
if we subsitute 1 for x we get
y=-4
which is not correct we want
x=1 and y=4 so
y=-4+8=4 so
y=-4x+8 is the equation
