Answer:
x intercept at (7/3 , 0)
y intercept at (0,-3)
Step-by-step explanation:
9x-7y=21
we need to find x and y intercepts
To find x intercept , plug in 0 for y
9x - 7(0) = 21
9x = 21
divide by 9 on both sides
x= 21/ 9 = 7/3
so x intercept at (7/3 , 0)
To find y intercept , plug in 0 for x
9(0) - 7(y) = 21
-7y = 21
divide by -7 on both sides
y= -3
so y intercept at (0,-3)
7 times 30 is 210
answer: 30
Answer:
40
Step-by-step explanation:
5 + 2 = 7
56 ÷ 7 = 8
8 × 5 = 40
Answer:
340000000
Step-by-step explanation:
3.4 x 10^8 is in scientific notation.
To change this to standard form you have to multiply 3.4 by 10 to the 8th power. You would be multiplying 3.4 by 10 eight times. It's a positive 8 so you move the decimal point 8 times to the right. If it were a negative then you'd move the decimal to the left.
3.4
<h2>
↑ moving the decimal 8 times to the right would then make it 340000000</h2>
