Someone help me please

Answers

Step-by-step explanation:

Q6

answer A, as x² is the regular parabolic curve up. and x²-3 just shifts this curve down by 3 units. and that is what we need, as the extreme point of the curve is a bit below the x-axis, and therefore has a negative y value.

Q7

answer C, as this curve is the complete opposite of the curve in Q6.

it is the regular parabolic curve but down. that means -x².

but the extreme point is a bit above the x-axis (and has therefore a positive y value). -x²+3 shifts the parabolic curve up by 3 units.

Q8

answer A again. the functional values are only positive (the whole curve is above the x-axis). so, C and D are therefore wrong.

and between A and B we need to remember, that a negative exponent means 1/...

in case of B 1/(2^x).

and that would mean for large positive x we would get very small values for y.

but we see the opposite. for large x we also get large y.

so, it is 2^x (answer A).

If x + y = 10 and x - y = 4, find the value of x² - y²

Answers

Answer:

x²-y² = 40

Step-by-step explanation:

Factorising x²-y²:

x²-y² = (x+y)(x-y)

This is due to the property that states:

a²+b² = (a+b)(a-b)

Substituting the given values into the above equation:

x²-y² = (10)(4)

= 40

Hence, x²-y² = 40

Step-by-step explanation:

1) 5 times 9 equals 45, then you add 5 to get 50.

2) -2 times 8 equals -16, minus 3 is the same as adding a -3 to get -19

3) 7 times 5 equals 35, plus 1 to get 36.

4) 72 divided by 6 equals 12, minus 10 to get 2.

5) 40 minus 14 equals 26, divided by 2 to get 13.

6) 3 times 3 equals 9, minus 5 to get 4 then multiplied by 4 to get 16 as your final answer.

on a sunny day liam decided to walk to his grandmother's house. After walking for a while at a rate of 3 mph, Liam realized that it might start raining, so he decided to take a taxi the rest of the way. The taxi traveled at a speed of 30mph. If he arrived 2 hours before he started, what distance did liam traveled by taxi?

Answers

The answer is ten. The formula for calculating speed is as follows:

Speed = distance × time. Knowing the distance and time units is required to calculate the speed units.

Explain about the speed?

A bicycle that travels 30 meters in two seconds, for example, is moving at a rate of 15 meters per second. The speed of an object in motion varies frequently (for example, a car may travel down a street at 50 km/h, then slow to 0 km/h, and then accelerate to 30 km/h).

The rate at which a distance changes over time is referred to as speed. It has a dimension of time and distance. As a result, the SI unit of speed is formed by combining the fundamental unit of time and the fundamental unit of distance. As a result, the SI unit of speed is the meter per second (m/s).
