Answer:
14
Step-by-step explanation:
Answer:
(-4, 1)
Step-by-step explanation:
Solve it as a system of equations:
[tex]3x-2y=-14\\3x+y=-11[/tex]
subtract the two equations
[tex]-3y = -3[/tex]
divide both sides by -3
[tex]y=1[/tex]
Plug this into the equation 3x + y = -11 to solve for x
[tex]3x + 1 = -11\\[/tex]
subtract 1 from both sides
[tex]3x = -12[/tex]
divide both sides by 3
[tex]x = -4[/tex]
So the answer is (-4, 1)

The domain is just asking for all the possible x values
The x value that's furthest to the left is -7 and because it's an open circle we write ( instead of [
the furthest to the right the line goes is 4 and because the circle is closed it's written with ]
but it all together and get
(-7,4]
What is not a description of slope?
rise over run
the rate of change of a line
change in yover the change in x
the ratio of horizontal change compared to vertical change
Answer:
the ratio of horizontal change compared to vertical change
Step-by-step explanations
slope = difference of y/ difference of x
rise (y) over (/) run (x)
change in y over change in x (y/x)
horizontal change (x): to vertical change (y) WRONG

Walter and Denise ordered a dessert to share at a restaurant. If Denise ate 1 8 of the dessert and Walter ate 4 5 of the dessert, what fraction of the dessert was left over?
Answer:
3/40
Step-by-step explanation:
Walter and Denise ordered a dessert to share at a restaurant. If Denise ate 1/8 of the dessert and Walter ate 4/5 of the dessert, what fraction of the dessert was left over?
Let the total dessert be represented as = 1
The fraction of the dessert left over =
1 - (4/5 + 1/8)
Lowest Common Denominator = 40
1 - (4 × 8 + 1 × 5/40)
1 - (32 + 5/40)
1 - 37/40
Lowest Common Denominator = 40
40 × 1 - 37 × 1/40
40 - 37/40
= 3/40
Therefore, the fraction of dessert that is left over = 3/40

is 5m^3 -3m^4-7m a polynomial? State the type and degree of the polynomial.
Answer:
Yes it is a polynomial.
It is a trinomial.
The degree is 4.
Step-by-step explanation:
So polynomial is an expression that has variables, constants, and exponents. And all of these are connected through things like addition and subtraction. In this question, you have x as your variable, 0 as your constant, and 4,3,1 as your exponents.
A term is the part of the polynomial that is separated by + or - sign. So in this question, you have 5m^3, -3m^4, and -7m as your terms. Because you have three terms, therefore this is a trinomial.
The degree of polynomial is represented by the variable with the largest exponent, so in your case, 4 is your largest exponent, therefore the degree of the polynomial is 4.

Step-by-step explanation:
The 30 represents how many problems there were in all
Hope I was Helpful!!
Ohhhhh No wait the answer is . 80 Im so sorry
B. 0.80
So, 24 out of 30 is equal to 80%.
If 100% = 1.0
Then 80% = 0.80
Hope this helps you out! Good luck. :)

Step-by-step explanation:
The aspect ratio of a TV screen is the ratio of the horizontal length to the vertical height. If the TV has a diagonal of 100 cm and the aspect ratio is 4:3, then find the horizontal length and the vertical height of the TV screen.
Answer:
The horizontal length is 80 cm, and the vertical height is 60 cm.
Step-by-step explanation:
The aspect ratio is the ratio of the horizontal length to the vertical height.
We have a rectangle with sides 4 and 3. We can find the length of the diagonal.
We can use the Pythagorean theorem to find the length of the diagonal.
a^2 + b^2 = c^2
3^2 + 4^2 = c^2
9 + 16 = c^2
c^2 = 25
c = 5
The diagonal is 5 in the ratio.
The ratio of the horizontal length to the vertical height to the diagonal is
4:3:5
We multiply all the numbers in the ratio by the same unknown, x.
A ratio of 4:3:5 is the same as a ratio of 4x:3x:5x.
We are told that the diagonal is 100 cm, so we have
4x : 3x : 100,
but we already had a ratio of
4x : 3x : 5x, so
5x = 100, and we can find x.
5x = 100
Divide both sides by 5.
x = 20
Since x = 20, then the horizontal length 4x = 4(20) = 80,
and the vertical height 3x = 3(20) = 60
Answer: The horizontal length is 80 cm, and the vertical height is 60 cm.
Answer:
horizontal length=80, vertical length=60
Step-by-step explanation:
a^2 + b^2 = c^2
the tv is a 3:4:5 right triangle
the ratio is then changed from
3:4:5
to
60:80:100
because 100/5 = 20
so you multiply the original ratio by 20
(because the length of 100 that we are given is the hypotenuse of the triangle(diagonal of the tv))
Therefore,
the horizontal length is 80
the vertical lengt is 60
What is the value of the expression below when a = -2, b = 3, C = -5
[a– 2ac + 56]
Answer:
34
Step-by-step explanation:
plug the coefficients in the equation, so
-2-2(-2)(-5)+56
Distribute the -2(-2)(-5), so it equals -20
so the equation is -2-20+56
add -20+56, so -2+36
-2+36=34
34 is your answer

PLEASE HELP ME I HAVE BEEN IN THIS QUESTION FOR MORE THAN 10 MINUTES PLEASE HELP
Answer:
31.40 ft^2
Step-by-step explanation:
You are trying to find the circumference, C = 2 * r * 3.14
1. To get the radius you divide the diameter by 2: 10 / 2 = 5
2. Plug your radius into the equation
C = 2 * 5 * 3.14
3. Your final answer should be 31.40 ft^2

-10b + 5 = 7b + 5
step by step
Answer:
b = 0
Step-by-step explanation:
Let's solve your equation step-by-step.
−10b+5=7b+5
Step 1: Subtract 7b from both sides.
−10b+5−7b=7b+5−7b
−17b+5=5
Step 2: Subtract 5 from both sides.
−17b+5−5=5−5
−17b=0
Step 3: Divide both sides by -17.
−175/17 = 0/-17
0
