Answer:
Just see that the first expression has all negative, meaning the total will be a negative, but the second expression the subtraction sign and the negative sign are together, there's a rule when two negative sign's are together/next to each other, they turn into a addition sign, so it basically 8 + 20 for the second expression, so 8-(-20) has a higher result
Step-by-step explanation:
There's no work needed to be done :P
Answer:
The answer is all real numbers
She catched as bill 1 time
Numbers 1, 2 and 3 are attached while 4 & 5 will be written down.
4. the histogram and stem/leaf plot are showing the exact same data, and the data is sorted by the same grouping. the frequency table shows a different grouping but the same data is shown more in-depth.
5. the number of leaves, frequencies, and the height of the bars are related because they are different ways of showing the same groups of data just in different ways. The impact that the choice of intervals makes on this relationship in the data is how concentrated, or diverse the data is.
Hope I helped!
y = x^2 + 2x...eqn 1
y = 3x + 20...eqn 2
subst for y in eqn 1...
=> x^2 +2x = 3x +20
=> x^2 - x - 20 =0
=> (x-5) (x+4) =0
=> x = 5 or -4
for x =5, y = 35 (sub for x in eqn 1 or 2)
for x = -4, y = 8 (sub for x in eqn 1 or 2)
