1.43 x 10^7. Scientific notation moves the decimal to express the answer in a single whole digit. The exponent becomes 10^7, because you moved the decimal one place to the left, so you add 1 to your original exponent of 10^6.
55%. 40-18=22 and 22 of 40 is 55%
Answer:
Step-by-step explanation:
Given that,
3y=12+2x
To find the x-intercept will set y=0 because, at the intercept of x, the value of y is 0
Then, y=0
3y=12+2x
3(0)=12+2x
0=12+2x
2x=-12
divide both sides by 2
x=-12/2
x=-6
Also, to get the y-intercept, let set x=0, because, at the intercept of y, x = 0
3y=12+2x
3y=12+2(0)
3y=12
Divide both sides by 3
y=12/3
y=4
So, y-intercept 4
Also, the x-intercept is -6
Friving in opposite directions, Joe and Hannah become (45+40)= 85 more miles apart rvery hour. They are 510 miles apart after (510/85)= 6 hours.
