It’s either Option 1 or 4
Answer:
If x = time in seconds, the answer is 1 second.
Step-by-step explanation:
The question is asking for the maximum height and the time it was achieved, so in terms of a graph, it is the vertex coordinates. Luckily this equation is in vertex form, so it gives us those points. The -1 in the equation is the x, but you invert this sign, because even thought the value on the graph is positive, it tells you to subtract 1, therefore adding -1, so for this part (the x part of the equation) remember to invert the sign.
The other part (the height) comes from the equation adding 45 at the end. This is the highest y point, and therefore the answer is (1,45), 1 second for 45 meters high.
Answer:
7=x
Step-by-step explanation:
.5(6x-4)=4x-9
3x-2=4x-9
subtract 3x to each side
-2=x-9
add 9 to each side
7=x
When distributing the negative to the (5-9y) you need to distribute it to both the 5 and the -9 so your 9 should be positive now. So it should be 72+24y = 4y-5+9y
Answer:
36
Step-by-step explanation:
Since BD is similar to GI, the ratio of the sides of the triangles is 27:3=9:1. This means that BC is 9 times larger than BH, or 4*9=36 units long. Hope this helps!
