Just do 18 divided by 6, and make your answer a negative. The answer is -3
Answer:
21 cm²
Step-by-step explanation:
A = (b + B)×h/2
= (5 + 9)×3/2
= 14×3/2
= 7×3
= 21 cm²
Answer:
X Intercept: (-10,0), Y Intercept: (0,2)
Step-by-step explanation:
Well, firstly you need to rewrite the equation to make it easier. After rewriting it you have the equation y=x/5+2 by adding the x to the right side and dividing everything by 5. Now simply plug in your zeroes in their respective places. For the x intercept, your y value must equal 0 so we have the equation 0=x/5+2. After solving it, x must be -10 in order for our y value to be 0 getting us for the x intercept (-10,0). For the y intercept, your x value must equal zero so you simply subsitute zero in the equation for x which I will do here: y=0/5+2. If our x value is zero, consequently, our y value will be 2 getting us for the y intercept, (0,2).
It is just the multiplication of vectors. We'll multiply corresponding pairs together. The general formula for the pairs of (
