Answer:
[tex]x=0.5[/tex]
[tex]y=anything[/tex]
Step-by-step explanation:
15−x+y=14−(−x−y)
15-x+y=14+x+y
Subtract 14 from both sides
1-x+y=x+y
Subtract y from both sides
1-x=x
Add x to both sides
1=2x
2x=1
Divide both sides by 2
x=0.5

You hungrily remove frozen meat from the fridge. Its temperature is -18 degrees celsius but you can start cooking it only when it reaches 15 degrees celsius. Its temperature is increasing by 3 degrees celsius every minute. How many minutes will you have to wait before you can start cooking? *
Answer:
start at -18 degrees
To get to 15 it would be 33 degrees increased
1 min = 11 minutes
3 degrees = 33 degrees
You would have to wait 11 minutes

Definition of Complementary Angles
Answer:
Add to 90 degrees
Step-by-step explanation:
Complementary angles are angles that add up to 90 degrees or a right angle. For example,
52°+38°=90°
Therefore, 52 and 38 are complementary angles.
-7 -5(-4c+4) <-7c+8-3
Answer:
c < 32/27
Step-by-step explanation:
−7−5(−4c+4)<−7c+8−3
Step 1: Simplify both sides of the inequality.
20c−27<−7c+5
Step 2: Add 7c to both sides.
20c−27+7c<−7c+5+7c
27c−27<5
Step 3: Add 27 to both sides.
27c−27+27<5+27
27c<32
Step 4: Divide both sides by 27.
27c/27 < 32/27
c < 32/27

What is the standard form of function f?
f(x) = 4(x + 6)^2+ 5
Substitute numerical values into the equation for a, b, and c.
F(x) = ax^2 + bx + c
Answer:
f(x) = 4x² + 48x + 149
Step-by-step explanation:same as the one above me.
The numerical values in the equation for a, b, and c will be 4, 48, and 149, respectively.
What is a function?A function is an assertion, concept, or principle that establishes an association between two variables. Functions may be found throughout mathematics and are essential for the development of significant links.
The quadratic equation is given as ax² + bx + c = 0. Then the degree of the equation will be 2.
The quadratic function is given below.
f(x) = 4(x + 6)²+ 5
Convert the equation into a standard form. Then we have
f(x) = 4(x + 6)²+ 5
f(x) = 4(x² + 12x + 36)+ 5
f(x) = 4x² + 48x + 144 + 5
f(x) = 4x² + 48x + 149
The numerical values in the equation for a, b, and c will be 4, 48, and 149, respectively.

Answer:
f(x) = 0.5x + 2
f(x) = 1/2x + 2
y - 3 = 1/2(x - 2)
y - 1 = 0.5(x + 2)
Step-by-step explanation:
In the figure attached, the graphed line is shown.
The missing options are:
f(x) = 0.2x - 4
f(x) = 0.5x + 2
f(x) = 1/2x + 2
y – 3 = 1/2(x – 2)
y – 1 = 0.5(x + 2)
From the picture, we can see that points (0, 2) and (2, 3) are on the line. Then, the slope of the line is:
m = (3 - 2)/(2 - 0) = 1/2 = 0.5
The y-intercept is (0, 2), or b = 2
Therefore, in the slope y-intercept form, the equation is:
f(x) = mx + b
f(x) = 1/2x + 2 = 0.5x + 2
In the point-slope form, the equations is:
y - y1 = m(x - x1)
y - 3 = 1/2(x - 2)
Using point (-2, 1), in the point-slope form, the equation is:
y - y1 = m(x - x1)
y - 1 = 0.5(x + 2)

Find the value of x in the question
Answer:
x=52
Step-by-step explanation:
r=90 s=34 q=180-(90+34)
180-(90+34)=56
to find angle sqr
180-56=124
124=x+72
52=x
Answer:
x = 52
Step-by-step explanation:
→We are given an exterior angle (outside of the triangle) as (x + 72). We are also given two interior angles as 34 and 90. The sum of the two farthest interior angles away from the exterior, is equal to the exterior. So this means that ∠R(90°) + ∠S(34°) = ∠PQS(x + 72), and we can set up the equation like that:
90 + 34 = x + 72
→Add like terms (90 and 34):
124 = x + 72
→Subtract 72 from both sides:
52 = x
Lucas attends 8 classes each day. If each class is about
45 minutes long, about how long will Lucas have been
in school when he starts his fourth class of the day?
He will have 3 classes done before starting the fourth class.
3 classes x 45 minutes per class = 135 minutes.
1 hour = 60 minutes
134 minutes = 2 hours and 15 minutes.
Before the fourth class starts he was at school for 2 hours and 15 minutes
PLEASE HELP!! The question is “ Abbey spends 5 hours less then triple the amount of time Emily spends on homework. Nathan spends twice as much time on homework as Abbey does. Write a simplified expression for the total number of hours the three friends spend on their homework. Show your work.”
Answer:
5(2x-3)
Step-by-step explanation:
Let the amount of time Emily spends on homework.=x (in hours)
Abbey's Time = 5 hours less than triple the amount of time Emily spends
Therefore:
Amount of Time spent by Abbey =3x-5Nathan's Time = Twice as much time as Abbey.
Amount of Time spent by Nathan =2(3x-5)Next, we calculate the total number of hours the three friends spend on their homework
=Time spent by Emily+Time spent by Abbey+Time spent by Nathan
=x+(3x-5)+2(3x-5)
=x+3x-5+6x-10
Collect like terms
=x+3x+6x-5-10
=10x-15
Next, we simplify by factorizing
Therefore, Total number of hours =5(2x-3)

the cougars baseball team played 16 games last year and won 12 of them. this year they are scheduled to play 28 games. if the end up with the same winning percentage, how many games will they win
Answer:
They won 21 games
Step-by-step explanation:
First take the 12 out of 16 games they have won and make it a fraction, 12/16. Then divide 12 by 16, 12 ÷ 16 and then you get, 0.75 then as always multiply it by 100 and get 75 (you can also just move the decimal over 2 places) Then after that you smack that percentage sign on 75 and get %75. So now we know that the Cougars baseball team won %75 of there games. Now take 28 and put it as a fraction, but! You need two numbers for it to be a proper fraction to we will replace the numerator with W to represent how many games they won, so now you should have something like this W/28, so now we find the value of W and by doing that just guess and check (it cant be over 28 so it must be under 28) and when your looking for your number do W ÷ 28 and try to get 0.75 and when you get that (that being 21 ÷ 28 = 0.75 ) you now know that 21 is your answer.
