a parallel line has the same gradient, so the gradient would be 3 1/3
a perpendicular line has the negative inverse gradient of the original (eg. if the original gradient is 4/3 then the perpendicular gradient would be -3/4 (all you have to do is change the +/- sign and flip the fraction), so in your case the gradient of the perpendicular line would be -3/10 (since 3 1/3 = 10/3)
Answer:
X=7
Step-by-step explanation:
These are supplementary angles. So they measure to 180º. 180º-95º=85º. 85º-10= 84º. 84º÷12x= 7.
Answer:
C
Step-by-step explanation:
hi! a horizontal line's slope is always 0.
hope this helps:)
Answer:
Rational Numbers
Step-by-step explanation:
- An integer in its most simplified form cannot be a decimal nor a fraction, meaning -4/3 nor -0.75 would work.
- A whole number is a number that is either positive or negative but cannot be a decimal in simplified form. -4/3 is -1.333.... which is less than one and negative, meaning it cannot be a whole number due to it obviously being a decimal.
- -4/3 is not a natural number as it is both a decimal and negative.
- -4/3 is not irrational because it repeats when in decimal form.
- -4/3 is rational as in decimal form it repeats and to give more information, rational numbers can be both positive and negative numbers. The 3 that repeats in the decimal form of -4/3 works as a rational number due to this.
Therefore, it would apply to the first square.

If you use fractions, the answer you get will always be an exact answer in the form of a fraction. resorting to decimals means that you may run into rounding errors and therefore get only an approximate answer. e.g. the fraction 1/3 cannot be exactly represented by a decimal.fractions can be easier to represent the number rather then using decimals which involve writing out many numbers it does not affect the accuracy of the answer UNLESS you are rounding up and down the numbers
