How can you represent an decrease in temperature using an addition equation? Explain!
Complete the equation of the line whose y-intercept is (0,5) and slope is -9.
y=
Answer: y=-9x+5
Step-by-step explanation:
slope intercept form is y=mx+b
simply plug in the values.
m= the slope
the slope you gave was -9, so plug that in to m.
b= the y intercept aka when the number touches the y axis. in this case, it would be 5.
y=-9x+5
solve for m
–m + 8 = –4m − 10
Answer:
m=-6
Step-by-step explanation:
-m + 8 = -4m -10
+m. +m.
8= -3m -10
+10. +10
18 = -3m
/-3m /-3m
-6=m
Answer:
m=-6
Step-by-step explanation:
–m + 8 = –4m − 10
Subtract 8 from both sides
-m+8-8=-4m-10-8
Simplify:
-m=-4m-18
Add 4m to both sides
-m+4m=-4m-18+4m
Simplify:
3m=-18
Divide both sides by 3
3m/3=-18/3
-18/3=-6
m=-6
Help!!! Please help me I need help on my homework!
Answer:
25 degrees and 45 degrees
Step-by-step explanation:
A triangle's angles HAVE TO add up to 180 degrees, no more no less. 110 + 45 + 25 = 180
pls help me with this asap you dont have to give a big explanation i mostly need the answer
Answer:
because 3 spheres is inside the cylinder and they are placed close together
=> The height of the cylinder is 3 times the diameter
=> the height is 18cm
the volume of the cylinder is 3,14.18.(6/2)² = 508,68
because 3 spheres have the same diameter
=> the volume of 3 spheres is 4.3,14.3³ = 339,12
=> the volume of the cylinder that is left empty is 508,68 - 339,12 = 169,56
Step-by-step explanation:
Answer:
The answer is 508,68
Step-by-step explanation:
Since the volume of the cylinder is equal to the area of the permanent base multiplied in the height
Since the radius of the base is equal to 3 and since the area of its cylinder is equal to
[tex]314 \times 3 \times 3 = 28.26[/tex]
When the height equal to 18
Then the volume equal to
[tex]28.26 \times 18 = 508.68[/tex]

Determine whether the expression is a polynomial. If it is a polynomial, find the degree
and determine whether it is a monomial, binomial, or trinomial.
2x^-3-4x+1
Answer:
hello again !
this isn't classified as a polynomial because polynomials do not contain variables raised to a negative number, such as this, which is raised to -3.

An obtuse triangle has two angles that measure 28° and 102°, what is the measure of the third side?
Answer:
50 degrees
Step-by-step explanation:
Well, all triangle's angles should add up to 180, so
102+28=130
180-130=50
Can you help me thank you
Answer:
D
Step-by-step explanation:
If you multiply one side by 4, you have to multiply both sides by 4. D is the only one who multiplies both sides by 4, so it is the correct answer.

The volleyball team needs new uniforms. The students plan to sell plush toy eagles (the school mascot) for $5 each. The students find three companies on-line that sell stuffed mascots. Company A sells 12 eagles for $34.56. Company B sells 15 eagles for $42.90. Company C charges $51.30 for 18 eagles. Which company has the best buy?
Answer:
Step-by-step explanation:
A=34.56/12=$2.88 each
B=42.90/15=$2.86 each
C=51.30/18=$2.85 each
So C is the cheapest.

c) Simplify fully
(5x – 10x2) /(14x - 7)
Answer:
- [tex]\frac{5x}{7}[/tex]
Step-by-step explanation:
Given
[tex]\frac{5x-10x^2}{14x-7}[/tex] ← factor out 5x in the numerator and 7 in the denominator
= [tex]\frac{5x(1-2x)}{7(2x-1)}[/tex] ← factor out - 1 on the numerator
= [tex]\frac{-5x(2x-1)}{7(2x-1)}[/tex] ← cancel the common factor (2x - 1)
= - [tex]\frac{5x}{7}[/tex]

Martha rented a sedan at a cost of $21.25 a day for three days. She drove 980 miles at 25 cents a mile. Gas cost $63.45 what was the cost per mile
Answer:
38 cents per mile
Step-by-step explanation:
Let us first calculate the total expenditure by Martha
= 21.25*3= $ 63.75
Cost of gas =$ 63.45
Therefore cost per mile = 127.2/980= 0.1297+0.25= $0.3797 or 38 cents per mile
When looking at a graphed System of Equations,
how do you determine which line is the better
deal?
Answer:
Step-by-step explanation:
So, if we are looking to save money, then it would probably be a good choice to go for the least steepest line. Assuming Money stands for the Y axis and Quantity stands for the X axis, then looking at the least steepest line means the lowest Y axis, which translates to the least amount of money.
