Answer:
the value of X is 122
Step-by-step explanation:
First, all triangle angles add up to 180 so to find the missing angle we subtract 51 and 71 from 180 and get 58
Now we know straight lines always equal 180 as well so we subtract 58 from 180 and get 122 and that is the value of x
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>
Answer:
(0,8)
Step-by-step explanation:
Let X be 0 and solve for Y to get the intercept
y= - 4() + 12
y= - 4 * + 12
y= - 4 * 1 + 12
y= - 4 + 12
y=8
when x=0, y=8
(0,8) is y intercept
