Answer:
the temperature dropped to -5 by 4:00 am
Step-by-step explanation:
Use f(x)=-4x+1, g(x)=x^2-8x+21, and h(x)=║9-3x║ for these equations.
Find g(-5)
Find g(x+4)
If f(x)=53, find x.
Step-by-step explanation:
For each problem, plug in the values, then simplify.
g(x) = x² − 8x + 21
g(-5) = (-5)² − 8(-5) + 21
g(-5) = 25 + 40 + 21
g(-5) = 86
g(x) = x² − 8x + 21
g(x+4) = (x+4)² − 8(x+4) + 21
g(x+4) = x² + 8x + 16 − 8x − 32 + 21
g(x+4) = x² + 5
f(x) = -4x + 1
53 = -4x + 1
52 = -4x
x = -13

Match the picture to the reason that would prove the triangles congruent.
Options:
NONE
ASA
SSS
SAS
AAS
HL
Answer:
HL (Hypotenuse Leg)
Step-by-step explanation:
You have BC=CD (Because of reflexive property), AC=DC, and measure of BAC is equal to the measure of BDC, which is 90 degrees. Since these triangles are right and they have a hypotenuse and a leg congruent, you can say that they are congruent because of HL.

Answer: In the chart, put 6 in place of the question mark.
The equation should be something like w = 2/3 p
W is the number of quarts of water. P is the number of quarts of Pineapple juice.
This week they will need 3 times the previous week so 18 quarts of pineapple juice and 12 quarts of sparkling water.
Step-by-step explanation:
If the basic recipe is 2 water to 3 juice, and they used 4 quarts if water, you can see that is double the amount of water so you need double the amount of juice. 2 times 3 is 6.
Unit rate means for ONE quart of juice, how much sparkling water is used. that should be 1 Pineapple Juice for 2/3 Sparkling water
OR
for EACH quart of sparkling water, how much juice do you need.
that would be 1 unit of Sparkling Water for 1 1/2 units of Pineapple Juice

Casey is making a flower arrangement with roses r and carnations c the cost of each rose is $0.50 and the cost of each carnation is $0.10 . the arrangement has a total $20. how many of each flower did Casey put in his arrangement
Answer:
r+c=80
.50r+.10c=20
Step-by-step explanation:
each rose costs $0.50
each carnation costs $0.10
The number of roses is r, and the number of carnations is c.
the arrangement has a total of 80 flowers, so we have that:
r + c = 80
the cost is $20, so we have:
r*0.5 + c*0.1 = 20
so our system of equations is:
r + c = 80
r*0.5 + c*0.1 = 20
and we can also solve it; for this isolate one of the variables in the first equation:
r = 80 - c
now let'r replace this in the second equation:
(80 - c)*0.5 +c*0.1 = 20
40 - c*0.4 = 20
c = 20/0.4 = 50
this means that we have 50 carnations, and the other 30 are roses.

Bradley estimated the height of a tree at 2.5 meters. Carla estimated that tree's height at 8 feet.
How could a conversion ratio be used to compare Bradley's and Carla's estimates of the tree's height when measured in feet? (1 foot = 0.305 meters)
Answer: 4.1 feet : 4 feet
Step-by-step explanation:
From the question, we are informed that Bradley estimated the height of a tree at 2.5 meters. Carla estimated that tree's height at 8 feet.
The conversion ratio be used to compare Bradley's and Carla's estimates of the tree's height when measured in feet goes thus:
Since 1 feet = 0.305 meters
2.5 meters will be = 2.5/0.305 = 8.2 feet
Therefore the conversion ratio will be:.
= 8.2 : 8
Reducing to lowest term will be
= 4.1 feet : 4 feet.
= 4.1 : 4

Susan owes $15,000 in student loans. She pays $150 toward the debt every month. Represent the total amount that she owes as a function of months (x) after each payment?
Answer:
f(x) = 15000 - 150x
Step-by-step explanation:
Given that:
Initial Amount owed = $15000
Amount payed towards debt per month = $150
Total amount owed as a function of month(x) after each payment :
F(x) = Initial amount owed - (amount paid per month * number of month)
Let number of month = x
f(x) = 15000 - 150x
Hence, the function ;
f(x) = 15000 - 150x represents the total amount owed after each payment.

What is the value of |– 4.25|?
Answer:
4.25
Step-by-step explanation:
|– 4.25| change to 4.25 and that's how it works
The required value of the expression given of absolute function is 4.25.
Given that,
An expression is given |-4.25|, a simplified value of the expression is to be determined.
The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
Here,
The given expression consists of an absolute function,
So the property of an absolute function is to give an outcome of positive values of the existing value always,
Following the above property,

Find one or more sequences of rigid motions and dilations that will map ABC to DEF Often, there is more than one sequence that will
nap a prelmage to a similar image. The table below provides spaces for two different sequences.
Begin by setting the scale factor of each dilation equal to the ratio you computed in question 1. Then find the rigid transformations needed to
complete the mapping Perform the transformations in GeoGebra to check your sequences.
