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.

f(x) = -4x^2 + 5x
Find f(6)
Answer:
-114
Step-by-step explanation:
f(6) it means f(x=6) so substituting x=6 in your equation gives us
f(6)= -4*(6)²+5*(6)
= -4*36+30
= -144+30
= -114

A.80 in sq
B.140 in sq
C.70 in sq
D.35 in sq
Answer:
C. 70 in sq
Step-by-step explanation:
The formula of a trapezoid is the A = a + b / 2 multiplied by height. (a and b are the bases). If you plug in the numbers into the formula, you will get 70.
Which step could be used to solve x + 3.6 = negative 1.7 for x in one step? Select two options. Add 3.6 to both sides. Add Negative 3.6 to both sides. Add 1.7 to both sides. Add Negative 1.7 to both sides. Subtract 3.6 from both sides.
Answer:
Subtract 3.6 from both sides.
Step-by-step explanation:
Given
[tex]x + 3.6 = -1.7[/tex]
Required
Solve in one step
There are two ways to go about it.
1. Collect Like Terms
[tex]x + 3.6 = -1.7[/tex]
3.6 and -1.7 are like terms, so the equation becomes
[tex]x = -1.7 - 3.6[/tex]
[tex]x = -5.3[/tex]
2. Subtract 3.6 from both sides
[tex]x + 3.6 = -1.7[/tex]
This becomes
[tex]x + 3.6 - 3.6 = -1.7 - 3.6[/tex]
[tex]x = -5.3[/tex]
Hence, the last option answers the question.
Answer:
Option 2and 5 are correct.
Step-by-step explanation:
-Add -3.6 to both sides
-Subtract 3.6 from both sides

Drum lessons at the youth club cost $8 each for members. There is a membership fee of $24. For non membership, each drum lessons cost $12. For what number of lessons is the cost the same for a member and non member
Answer:
6
Step-by-step explanation:
Given that:
One time membership fee = $24
Cost for each drum lesson at the youth club for members = $8
For non-members,
Cost for each drum lesson = $12
To find:
Number of drum lessons such that the cost for a member and a non-members is same.
Solution:
Let the number of drum lessons = [tex]x[/tex]
Cost for drum lessons for the members = Number of drum lessons [tex]\times[/tex] Cost for one drum lesson
Cost for drum lessons for the members = $[tex]8x[/tex]
Total cost for members = $24 + $[tex]8x[/tex]
Total cost for the drum lessons for the non-members = $12[tex]x[/tex]
As per question statement, both the expressions are equal:
[tex]24+8x = 12x\\\Rightarrow 12x-8x=24\\\Rightarrow 4x =24\\\Rightarrow x = 6[/tex]
For 6 number of lessons, cost for both will be same.

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

Solve –2k + 12 < 30 for k.
Answer:
k<-9
Step-by-step explanation:
First you want to isolate the variable, or k in this case. So you will subtract 12 on both sides which will leave you with -2k<18. Then you will divide both sides by -2. Which turns into k>-9. But since you divided by a negative, the sign changes, so the answer would be k<-9.

Find a number c such that the polynomial
p(x) = -x + 4x2 + cx3 - 8x4
has a zero at x =1/4
Answer:
c = 2
Step-by-step explanation:
Since the polynomial has a zero at x = [tex]\frac{1}{4}[/tex] , then p([tex]\frac{1}{4}[/tex] ) = 0, then
p([tex]\frac{1}{4}[/tex] )
- [tex]\frac{1}{4}[/tex] + 4([tex]\frac{1}{4}[/tex] )² + c([tex]\frac{1}{4}[/tex] )³ - 8[tex](\frac{1}{4}) ^{4}[/tex] = 0
- [tex]\frac{1}{4}[/tex] + 4([tex]\frac{1}{16}[/tex] ) + c([tex]\frac{1}{64}[/tex] ) - 8([tex]\frac{1}{256}[/tex] ) = 0
- [tex]\frac{1}{4}[/tex] + [tex]\frac{1}{4}[/tex] + [tex]\frac{c}{64}[/tex] - [tex]\frac{1}{32}[/tex] = 0 , simplifying gives
[tex]\frac{c}{64}[/tex] - [tex]\frac{1}{32}[/tex] = 0 ( add [tex]\frac{1}{32}[/tex] to both sides )
[tex]\frac{c}{64}[/tex] = [tex]\frac{1}{32}[/tex] ( multiply both sides by 64 )
c = 2

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.

Find the value of Angle A and B!!! Will mark brainliest
Answer:
A=73
B=107
Step-by-step explanation:
since the angles are across from eachother they would be the same, the total angle of all 4 added together would be 360, and 73+107 would be 180, so 180+180 is equal to 360

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%
