Note: I am assuming you meant to write the value of y = 12 instead of w = 12.
So, I am assuming y = 12
Answer:
The value of 13 - 0.75y + 8x when we substitute y = 12 and x = 1/2 will be: 8
Step-by-step explanation:
Given the expression
[tex]13\:-\:0.75y\:+\:8x[/tex]
Given
y = 12x = 1/2substituting y = 12 and x = 1/2 in the expresion
[tex]13\:-\:0.75y\:+\:8x=13\:-\:0.75\left(12\right)\:+\:8\left(\frac{1}{2}\right)[/tex]
[tex]=13-0.75\cdot \:12+8\cdot \frac{1}{2}[/tex]
[tex]=13-9+4[/tex]
[tex]=8[/tex]
Therefore, the value of 13 - 0.75y + 8x when we substitute y = 12 and x = 1/2 will be: 8

Step 1: Define Systems
y = 3x - 3
y = -4x + 4
Step 2: Solve for x
Substitution
Substitute in y: 3x - 3 = -4x + 4Isolate x terms: 7x - 3 = 4Isolate x term: 7x = 7Isolate x: x = 1Here we see that our x-value would equal 1.
∴ (-3, 0) is NOT a solution to the systems.

A batch has 15000 coloured bulbs. 3/5 of the batch are orange in colour & the rest are green . if 1/8 th of the green bulbs are not working , how many green bulbs are functional?
Answer:
5250 bulbs are functional green bulbs
Step-by-step explanation:
find out how much 1/5 of 15000 is
15000/5=3000
find out how many are orange
3/5=1/5+1/5+1/5 3000*3=9000
of the 15000 bulbs 9000 are orange the rest are green find the amount that is left over
15000-9000=6000 bulbs are green
find out what 1/8 of the green bulbs is
6000/8=750
1/8 or 750 green bulbs are not working
find out how many bulbs are functional
6000-750=5250 bulbs are functional green bulbs
3x-y=7 in slope intercept form
Answer:
y = 3x - 7
General Formulas and Concepts:
Pre-Algebra
Equality PropertiesAlgebra I
Standard Form: Ax + By = C
Slope-Intercept Form: y = mx + b
m - slope b - y-interceptStep-by-step explanation:
Step 1: Define
Standard Form: 3x - y = 7
Step 2: Rewrite
Find slope-intercept form
Subtract 3x on both sides: -y = 7 - 3xDivide -1 on both sides: y = 3x - 7Answer:
y = 3x + 7
Step-by-step explanation:
subtract 3x from both sides
multiply both sides by (-1) to get positive numbers

Y intercept: (0,7)
X intercept: (-7/4, 0)
Step-by-step explanation:
Step-by-step explanation:
finding y intercept:(x=0)
y=4x +7
=4(0)+7
y=7
finding x intercept:(y=0)
y=4x+7
0=4x+7
-7=4x

If a recipe calls for 12 oz. of chocolate chips for 2 batches, how many ounces of chocolate chips would you need for 1/2 a batch?
Answer:
3 oz.
Step-by-step explanation:
how many 1/2 are there in 2?
there are 4.
this means we divide 12 (oz. of choc chips) and 4
when we divide them, we get 3oz.
thats why you need 3oz. chocolate chips for 1/2 of a batch
hope this helps!

the cost for a bakery to make a dozen muffins is 2.52. the sale price of an individual muffin is 2.99. for one day, the bakery will donate 1/2 of the profits from muffin sales to charity. what is the bakeries donation, in dollars, if 88 muffins are sold that day
Answer:
I'm pretty sure it would be $131.56
Step-by-step explanation:
I think it will be $131.56 because if you take an multiply the 2.99 times 88 the number of muffins that were sold that day, then you would get $263.12. If you donated 1/2 of the profits made, then you would take 263.12 and divide it by 2 because half of it would be divided by 2. So therefore you would get $131.56! Hope this helps!
Correct me if I'm wrong!
Consider the system of inequalities.
3x + 2y < 8
-5x - 9y > -2
Select all ordered pairs that are solutions to the system of inequalities.
(-10, -3)
a)
b)
(-1, 5)
(0, 0)
d)
(1, -1)
Answer:
b)
The point is (-1,5) and (0,0) also satisfies the given inequalities
The solution of the given inequalities
(x, y) = (4 , -2 )
Step-by-step explanation:
Step(i):-
Given system of equations are
3x + 2y < 8
-5x - 9y > -2
The solution of the given equations are
3x + 2y = 8 multiply '5'
-5x - 9y = -2 multiply '3'
15 x + 10 y = 40 ...(i)
-15x - 27 y = -6.....(ii)
Adding (i) and (ii) , we get
- 17 y = 34
y = -2
Substitute y = -2 in equation 3x + 2y =8
3x - 4 =8
3x = 12
x =4
The solution of the given system of inequalities
(x, y) = (4 , -2 )
Step(ii):-
3x + 2y < 8
-5x - 9y > -2
The point is (-1,5)
-3 + 10 < 8
7 < 8
5 - 45 > -2
-40 > -2
The point (0,0) also satisfies the given inequalities
Final answer :-
The point is (-1,5) and (0,0) also satisfies the given inequalities

Jada traveled 135 miles in 3 hours. Andre traveled 228 miles in 6 hours. Both Jada and Andre traveled at a constant speed. A) How far did Jada travel in 1 hour?
Given:
Jada traveled 135 miles in 3 hours.
Andre traveled 228 miles in 6 hours. Both Jada and Andre traveled at a constant speed.
To find:
How far did Jada travel in 1 hour?
Solution:
We have,
Distance traveled by Jada in 3 hours = 135 miles
Then,
Distance traveled by Jada in 1 hour = [tex]\dfrac{135}{3}[/tex] miles
= 45 miles
Therefore, Jada travel 45 miles in 1 hour.
Evaluate -8 x |2|.
A.-16
B.-10
C.16
D.10
Step-by-step explanation:
|| represents the absolute value function:
|x| = x when x >= 0,
|x| = -x when x < 0.
Therefore (-8) * |2| = (-8) * 2 = -16. (A)
Answer:
Step-by-step explanation:
In step 1: mode will be solved so |2| will be absolute positive value of 2 which is 2
Step 2: multiply by -8 which is -16
So Answer is (A) -16

Answer:
What is the sum of the exterior angles in a regular 15-gon?
The sum of the exterior angles in any convex polygon, including a regular 15-gon, is 360∘.
Step-by-step explanation:
thank me later
mark me as brainliest please
Answer:
5 exterior angles.
Step-by-step explanation: since they all have to add to 360 you can divide 360/5 = 72. You can also check by adding one interior angle plus 72 and checking if you get 180.
