Mateo completed the following steps to solve the equation -2 + z = 10.
-2 + z = 10
-2 + z − 2 = 10 − 2
z = 8
Explain why Mateo's solution is incorrect. Then show how to correctly solve the equation.
if z = 8
then
-2 + (-8) = - 10
not 10
-2 + z = 10
-2 + 2 + z = 10 + 2
z = 12
check
-2 + (+12) = +10

Answer:
m = 2.4 and b = 14.8
Step-by-step explanation:
In slope-intercept form, all equations follow the formula y = mx + b, in which equations are parallel as long as they have the same slope, represented by the variable m. All that the b variable does is change the y-intercept. Knowing this, in order to find a parallel equation to y = 2.4x + 5.2 that intercepts the point (-2, 10), the only variable that can change is the b variable. The first step is to plus -2 into the x variable. This will grant you y = 2.4(-2) or y = -4.8, which will then allow you to find what the b variable should be by subtracting -4.8 from 10. This will grant you b = 14.8, and since you know the slope must stay the same, the final answers are m = 2.4 and b = 14.8.
Can someone please help me with this? I just need to know how it works and what the answer is.
Answer:
3
Step-by-step explanation:
Since you need to find the y value when x = -1, go to -1 on the x axis, and find where the green line crosses. The green line goes through the point (-1,3), or one box to the left and three boxes up, so the y value is 3.
Hopefully this helps- let me know if you have any questions!
Answer:Find the point in which the x = 1, and the y point meets.
When x = 1, y = 2
2 is your answer for y

The areas of the two rectangles below are equal. There are two possible areas. One is 105 u2
What is the other one?
Answer:
144 u²
Step-by-step explanation:
⇒ Areas are equal
(6x + 15)(2x + 7) = (4x + 7)(2x + 15)12x² + 42x + 30x + 105 = 8x² + 60x + 14x + 1054x² = 2xx = 1/2Calculating the areas
(6 x 1/2 + 15)(2 x 1/2 + 7) = 18 x 8 = 144(4 x 1/2 + 7)(2 x 1/2 + 15) = 9 x 16 = 144The other one is 144 u²

Dolbear's law states the relationship between the rate at which Snowy Tree Crickets chirp and the air temperature of their environment. The formula is T=50+n-40/4, where T is a temperature in degrees Fahrenheit and N is a number of chirps per minute. If T=57°F, find the number of chirps per minute.
Answer:
Number of chirps per minute = 68
Step-by-step explanation:
Given:
T = 50+ (N - 40)/4
where,
T is a temperature in degrees Fahrenheit
N is a number of chirps per minute
Find n when T = 57°F
T = 50 + (N - 40)/4
57 = 50 + (N - 40)/4
57 - 50 = (N - 40)/4
7 = (N - 40)/4
Multiply both sides by 4
7 × 4 = (N - 40)/4 × 4
28 = N - 40
28 + 40 = N
68 = N
N = 68
Number of chirps per minute = 68

Review the steps of the proof of the identity Sine (A minus StartFraction 3 pi Over 2 EndFraction) = cosine A.
Sine (A minus StartFraction 3 pi Over 2 EndFraction)
Step 1: = Sine A cosine (StartFraction 3 pi Over 2 EndFraction) minus cosine A sine (StartFraction 3 pi Over 2 EndFraction)
Step 2: = (Sine A) (0) + cosine A (negative 1)
Step 3: = (Sine A) (0) + (1) (cosine A)

[tex]\frac{4}{10}[/tex]Answer:
-2/5
Step-by-step explanation:
-[tex]\frac{2}{5}[/tex] ÷[tex]\frac{2}{1}[/tex]= -[tex]\frac{2}{5}[/tex]×[tex]\frac{1}{2}[/tex]=-4/10=-2/5
When dividing fractions you follow a rule called Keep change flip or KCF. You keep the first fraction in this case -2/5 then u change the symbol so from ÷ to × and then u flip the fraction. You then solve like you would a multiplication fraction.

An office supply store purchased a case of binders for $600. The profit (P) to be made on the binders is defined by the function
P(b) - 8.50b - 600, where b is the number of binders sold.
Part A What is the range of the function if the domain is {10, 45, 72, 100)?
Part B What do the domain and range represent in this situation?
Part C What is the minimum number of binders that the store needs to sell in order to make a profit (P >0)? Show or explain your work.
Part D What is the minimum profit the store can make on the sale of these binders? Show or explain your work.
Answer:
Part A
Domain = input values
Range = output values
Therefore, if the domain is {10, 45, 72, 100} then input those values into the function:
P(10) = 8.50(10) - 600 = -515
P(45) = 8.50(45) - 600 = -217.5
P(72) = 8.50(72) - 600 = 12
P(100) = 8.50(100) - 600 = 250
So the range is {-515, -217.5, 12, 250}
Part B
The domain is the number of binders sold
The range is the profit in dollars
Part C
Set the function to >0:
⇒ P(b) > 0
⇒ 8.50b - 600 > 0
add 600 to both sides:
⇒ 8.50b > 600
divide both sides by 8.50:
⇒ b > 70.58823529...
Therefore, the minimum number of binders the store needs to sell in order to make a profit is 71.
Part D
If the store sells a minimum of 71 binders, then substitute b = 71 into the function and solve to find the minimum profit:
⇒ P(71) = 8.50(71) - 600
⇒ P(71) = 603.5 - 600
⇒ P(71) = 3.5
Therefore, the store will make a minimum of $3.50 profit if it sells at least 71 binders.
However, if the store sells less than 71 binders, it will make a loss.
