Answer:
4. -2s^9
7. 8b^10
Step-by-step explanation:
First, focus on the number part of the expression. For 4), multiply -2 x -1 x -1 = -2. Then, look at the exponents. When you're multiplying exponents with the same base (in number 4, the base is s), you can add the exponents.
2+3+4 = 9; which makes it s^9. Multiply -2 x s^9, which gives you -2s^9.
Same thing for 7). Multiply all the numbers first. this gives you 8. (Remember two negatives equals a positive). Add all of the exponents of b together, which gives you 10. (when a variable has no exponent, it means that the exponent is 1.) Multiplying 8 and b^10 should give you 8b^10.
It may help to brush up on exponent rules and sign rules.
Answer:
AA
Step-by-step explanation:
12/8 = 1.5
21.6/14.4 = 1.5
18/12 = 1.5
the AA postulate states that two triangles are similar if they have two corresponding angles that are congruent or equal in measure
Answer:
y<= 2/5 x -8
Step-by-step explanation:
When we are dealing with inequalities we have to keep in mind that the graph are regions and not figures (like lines)
The region has orientation and it is given by the sign used, if it is above something, it means the > sign, otherwise the < sign.
Now, we have a line and the region is below, so there is a < sign involved, other thing to keep in mind is that the figure can be contained in the region if is graphed using a solid line, so there is the = sign involved
Answer:
1. y=7.2
2. x=18
Step-by-step explanation:
1. Triangles CMN and CBA are similar triangles (by AAA postulate). Similar triangles have proportional corresponding sides, so
2. GK is angle G bisector. Use angle bisector's property:
