Cell phone cases cost $12 each. Write an equation to find y, the total cost of x number of cases.
Answer:
y=12x
Step-by-step explanation
Let's assign meaning to the variables
y= the total cost
x=the number of cases purchased
Since y is the total it is going to be our ending value so y=12x
Hope this helps!
Which ordered pairs in the form (x, y) are solutions to the equation
7x−5y=28?
Select each correct answer.
A. (4, 10)
B. (−1, −7)
C. (7, 9)
D. (−6, −14)
When I tried to solve for 5y I got 5.6
Options B. (−1, −7) and D. (−6, −14) are correct which are the solutions to the equation.
What is a linear equation?It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
It is given that:
The equation is:
7x - 5y = 28
From the above equation:
y = mx + c
On comparing:
y = (7/5)x - 28/5
m = 7/5
c = -28/5
After plotting the graph of the equation:
From the graph:
B. (−1, −7)
D. (−6, −14) are the ordered pairs in the form (x, y) that are solutions to the equation.
Thus, options B. (−1, −7) and D. (−6, −14) are correct which are the solutions to the equation.

Marvin has a 27-foot ladder. Safety standards
dictate that the base of a 27-foot ladder should be
placed 7 feet from a vertical wall. How far above the
ground will the top of the ladder be on the wall, in
feet? (Round your answer to the nearest tenth.)
Answer:
15.1657508881 or 15.17
Step-by-step explanation:
I believe you are supposed to use the hypotenuse of a right triangle equation
a2+b2=c2
Let's begin! 27 feet is the hypotenuse (the longest part of a right triangle)(c)
so 7*7 is equal to 49
and 27*27 is equal to 279
Now you put the numbers back into the equation
49+b2=279, Now let's solve for b
279-49=230 b2=230
230 squared is 15.1657508881
Hope this makes sense!
Answer:
15.17

Ohm's law states that V=IR for a simple circuit, where V is the total voltage, I is the amount of current running through the resistor and R is the resistance of the resistor. If I=40 amperes when R=3 ohms, find the amount of current (in amperes) when the resistor has a resistance of 20 ohms. Assume voltage remains constant.

Write the equation of the line that has the following slope and y-intercept
Answer:
y=-4/3x+8
Step-by-step explanation:
The formula to create a linear equation is y=mx+b.
m = slope
b= y intercept
m= -4/3
b= 8

What are the like terms in the expression below?
3x + 8 + 3y + 8x
A 8 and 8x C 3x and 8x
B 3x and 3y D 3x, 3y, and 8
Correct answer:
C) 3x and 8x
Step-by-step explanation:
At first I thought the correct answer was D.
You may Have thought that too but that is not the correct answer.
You see 3x and 8x are both like terms because they both have x
but..
The other 3 does not have a x it has a y

could anyone give a simple answer? sorry if im asking so many questions, im just confused. Which table of ordered pairs represents a proportional relationship? A 2-column table with 3 rows. Column 1 is labeled x with entries negative 3, negative 4, negative 5. Column 2 is labeled y with entries 3, 2, 1. A 2-column table with 3 rows. Column 1 is labeled x with entries negative 1, negative 3, negative 5. Column 2 is labeled y with entries 1, 3, 5. A 2-column table with 3 rows. Column 1 is labeled x with entries negative 2, negative 4, negative 6. Column 2 is labeled y with entries negative 5, negative 7, negative 9. A 2-column table with 3 rows. Column 1 is labeled x with entries negative 2, negative 3, negative 4. Column 2 is labeled y with entries 0, negative 1, negative 2.
Answer:
A 2-column table with 3 rows. Column 1 is labeled x with entries 14, 28, 42. Column 2 is labeled y with entries 2, 4, 6.
Step-by-step explanation:
A 2-column table with 3 rows. Column 1 is labeled x with entries 16, 32, 48. Column 2 is labeled y with entries 1, 2, 4.
No, as x= 4 ⇒ y =64 not 48
A 2-column table with 3 rows. Column 1 is labeled x with entries 1, 5, 6. Column 2 is labeled y with entries 5, 20, 30.
No, as x = 5 ⇒ y = 25 not 20
A 2-column table with 3 rows. Column 1 is labeled x with entries 14, 28, 42. Column 2 is labeled y with entries 2, 4, 6.
Yes, as 2*7 = 14, 4*7= 28, 6*7= 42
A 2-column table with 3 rows. Column 1 is labeled x with entries 0, 1, 3. Column 2 is labeled y with entries 25, 70, 90.
No, x = 3 ⇒ y= 25+3*45= 160 not 90

In order to find the solution, You would first line line the equation up. then, you would subtract -200 by 15. The answer would be -185. I know the answer will be negative because -200 is too big for 15 to make the solution positive. If you had a positive 201 plus -200 the answer would be equivalent to a positive one because the positive would cancel out the negative.
Included: Negative, positive, equivalent.
explanation/ statement:
"I think I should subtract -200 by 15. which one equal -185. I know the answer will be negative because -200 is too big for 15 to make the solution positive.
In fact, If you had a positive 201 plus -200 the answer would be equivalent to a positive one because the positive would cancel out the negative one.
