hi can someone help please? thank you
pls this was due 2 months ago
Answer:
Similarities:
For both functions, x is increasing at the same rate.
They are both decreasing, which means that they’re reaching to the negative numbers.
Differences:
The y in Function 2 in increasing faster than Function 1, because Function 2 has a rate of change of -2, and Function 1 has a rate of change of -1 OR you can say that Function 2 has a slope of -2 and Function 1 has a slope of -1.
Function 2 as a y-intercept of 5, but Function 1 has a y-intercept of -3.
Hope this helps! :)

You plant a tree that is 36 inches tall. Aftler one yea, the tee is 43 inches tall. Which
expression descríbes the percent of increase ín the tree's heigh?
Answer:
% increase will be: 16.28%
Step-by-step explanation:
You plant a tree that is 36 inches tall.
Thus, the initial value = 36 inchesAfter one year, the tee is 43 inches tall.
Thus, the final value = 43 inchesTherefore, the percent of the increase will be:
% increase = 100% × (final - initial)/ initial
= 100% × (43 - 36)/36
= 100% × 7/36
= 100% × 0.16
= 16.28%
Thus, % increase will be: 16.28%

Sydney bought 5 new notebooks for $ 1.42 each and 15 pens that cost 3 for $1.20. How much change would Sydney get back if she gave the cashier a $20 bill?
Answer:
She will get $6.90
Step-by-step explanation:
5 × 1.42 = 7.10
15 ÷ 3 = 5
5 × 1.20 = 6.00
7.10 + 6.00 = 13.10
20.00 - 13.10 = 6.90

Please help me with two questions! Thank you so much!!
Answer:
See below
Step-by-step explanation:
DOK 3
[tex] In\: \triangle ABC, \:\\
m\angle A + m\angle B + m\angle C = 180\degree \\\\
m\angle A + 76\degree + m\angle C = 180\degree \\\\
m\angle A + m\angle C = 180\degree - 76\degree \\\\
m\angle A + m\angle C = 104\degree \\\\
\frac{1}{2} (m\angle A + m\angle C) =\frac{1}{2}\times 104\degree \\\\
\red{\bold{\frac{1}{2} (m\angle A + m\angle C) = 52\degree}}... (1)\\[/tex]
Since, AD and DC are bisectors of [tex] \angle A \: \&\: \angle C[/tex] respectively.
[tex] m\angle DAC= \frac{1}{2}m\angle A... (2)\\\\
m\angle DCA= \frac{1}{2}m\angle C...(3) \\[/tex]
Adding equations (2) & (3), we find:
[tex] m\angle DAC+m\angle DCA= \frac{1}{2}(m\angle A+m\angle C).... (4)\\[/tex]
From equations (1) & (4)
[tex] m\angle DAC+m\angle DCA= 52\degree... (5)\\\\
In \triangle ADC, \\
m\angle ADC + m\angle DAC +m\angle DCA = 180\degree... (6)\\\\[/tex]
From equations (5) & (6), we find:
[tex] m\angle ADC + 104\degree = 180\degree... (6)\\\\
m\angle ADC = 180\degree - 52\degree \\\\
\huge\purple {\boxed{m\angle ADC = 128\degree}}
[/tex]
DOK 4:
Let the measures of the angels 1, 2 and 3 be 4x, 5x and 6x respectively.
Therefore,
4x + 5x + 6x = 180°
15x = 180°
x = 180°/15
x = 12°
4x = 4*12° = 48°
5x = 5*12° = 60°
6x = 6*12° = 72°
[tex] m\angle 1 = 48\degree \\\\
m\angle 2 = 60\degree \\\\
m\angle 3 = 72\degree \\[/tex]

Answer:
H. The preimage and image will not have the same orientation but will be congruent.
Step-by-step explanation:
If you rotate something (say your phone), it will be a different orientation than when you stated unless you rotate it exactly 360 degrees (a full circle). Since 90 is not equal to 360, the arrow will not have the same orientation.
When you rotate your phone, it is still the same size and shape. This means that it is congruent. Same will happen with your arrow.
