Answer:
y= -10x +30
Step-by-step explanation:
It's going down by 10 every time so the slope is -10
(you could also use the formula of y2-y1 over x2-x1= 20-30/ 1-0= -10/1 or -10)
Since it is starting off at 30 the y intercept is 30
Markers were placed at altitudes of 10 and 15 feet below sea level.
Enter the integer that represents the altitude closer to sea level.
Helppppppppp please
Answer:
|10|
Step-by-step explanation:
Since 10 is negative (below the sea level), 10 is 10 spaces away from zero on the number line, meaning your answer is |10|.

A. 0 -1+ (1+21) + 5i
B. 20+68
C. 20+5i
D 22+6i
Answer:
i would say the answer is 20 + 6i but thats not an answer

O2.0 km/min
O 2.5 km/min
Answer:
2.0 km/min
Step-by-step explanation:
20/2=10
Hope this helps!!!
Answer:
2.0 km/min
Step-by-step explanation:
To find the average velocity, divide the number of km by the number of minutes:
20/10
= 2
So, the average velocity of the trip was 2.0 km/min
Michelle's car needs repairs. The mechanic said it will be $144 for parts plus $80 an hour to repair the car. How many hours can Michelle afford to pay the mechanic if she can spend no more than $384?
Answer:
3 hours
Step-by-step explanation:
Total cost = 144 + 80h
Where h = number of hours
How many hours can Michelle afford to pay the mechanic if she can spend no more than $384?
384 = 144 + 80h
Subtract 144 from both sides
384 - 144 = 144 + 80h - 144
384 - 144 = 80h
240 = 80h
Divide both sides by 80
h = 240 / 80
= 3
h = 3 hours

determine the domain of the following graph
Answer: [tex]-2 \leq x \leq 9[/tex]
Step-by-step explanation:
The domain is the set of x-values for which the relation is defined.
The domain of the graph will be -2 ≤ x ≤ 9 which is shown in the given figure.
What are the domain and range of the function?The domain of the function includes all possible x values of a function, and the range includes all possible y values of the function.
The domain of a graph is the set of all possible input values (also called the independent variable) that can be plotted on the graph. In other words, it is the range of values that the horizontal axis (also called the x-axis) of the graph covers.
To determine the domain of a given graph, you will need to look at the labels and scale of the x-axis.
The domain of a graph is the set of all possible input values in intervals as -2 ≤ x ≤ 9 that can be plotted on the graph.
Thus, the domain of the graph will be -2 ≤ x ≤ 9, as indicated in the illustration.

Find the exact length of the third side.
Answer:
[tex]24x^{2} +7x^{2} =[/tex]
step-by-step explanation:
You have to solve this to get your answer. This is a case where you have to use the pythagorean theorem.
Answer:
this is a right angle triangle.
which means that we can use hypotenuse theorem to solve it.
the hypotenuse theorem:-
a^2 +b^2 =c^2
where a and b are the sides opposite to the hypotenuse.
[(the longest side) the longest side of the triangle is always opposite to the right angle]
so...
a = 24
b = 7
a^2 + b^2 = c^2
24^2 + 7^2 = c^2
576 + 49 = c^2
625 = c^2
don't stop here, you could lose marks. I have seen my classmates do this silly and small mistake and lose 1/2 a mark.
√625 = c
25 = c
thus the length of the third side is 25.

i hope this helps.

Answer:
1/2x+5=10
subtracting 5 from both sides 1/2x+5-5=10-5
1/2x=5
divide both sides by 1/2
1/2x÷1/2=5÷1/2
x=5×2/1

Jasmine bought 3 slices of cheese pizza and 2 slices of pepperoni pizza for a total cost of $11.75. Keegan bought 2 slices of cheese pizza and 1 slice of pepperoni pizza for a total cost of $7. What is the cost of one slice of CHEESE pizza?
Answer:
$2.25
Step-by-step explanation:
Let c represent the price of cheese pizza and let p represent the prize of pepperoni pizza
3c + 2p= 11.75
2c + 1p = 7
Solve using elimination method
3c + 2p= 11.75 × 2
2c + 1p = 7 × 3
6c + 4p = 23.5
-
6c + 3p = 21
p = 2.5
Substitute 2.5 for p in equation 1
3c + 2p= 11.75
3c + 2(2.5) = 11.75
3c + 5 = 11.75
3c = 11.75-5
3c = 6.75
c= 6.75/3
c= 2.25
Hence the price of one slice of cheese pizza is $2.25
Answer:
$2.25

PLEASE HELP!! Determine whether the triangles are similar. If similar state how (AA~,SSS~, or SAS~), and write a similarity statement
Answer:
Yes they are similar because of SAS similarity
Step-by-step explanation:
the side lengths are proportional to each other, and the angle in the middle of the sides is the same size, therefore it has Side Angle Side (SAS) similarity.
ΔTSR ~ ΔFEG by the SAS Similarity Theorem
What is the SAS Similarity Theorem?SAS Similarity Theorem states that two triangles with two pairs of proportionate sides and a pair of included angle are similar to each other.
In the image given, the two triangles have:
Two pairs of proportional sides - TS/FG = TR/FE = 3.A pair of congruent included angles - ∠T ≅ ∠F.This means they are similar by the SAS Similarity Theorem.
Therefore, ΔTSR ~ ΔFEG by the SAS Similarity Theorem.

Hey if you see this question, and know the answer, then come and answer!
my little sister is having a test practice and for the table, in the picture, I need to know the constant proportionally, and the equation for the chart. Thanks so much yall!
please don't answer for points
love yall <3
Answer:
The constant of proportionality is 1/25.
Step-by-step explanation:
Chart values:
a | b
75 3
200 8
1525 61
10 0.4
To find the constant, divide your "b" values by your "a" values.
3/75 simplifies to 1/25 (GCF is 3)
8/200 simplifies to 1/25 (GCF is 8)
61/1525 simplifies to 1/25 (GCF is 61)
0.4/10 becomes 4/100, which simplifies to 1/25 (GCF is 4)
Since all four come to the same constant, 1/25 is the constant of proportionality.
The equation here would be:
[tex]b=\frac{1}{25}a\\b=\frac{a}{25}[/tex]
