Answer:
When c and a are positive or both are negative
Step-by-step explanation:
negative times negative equals positive so if a was negative and c was negative -a*-c= ac
Of course positive times positive equals negative so if a and c were positive we could do
a*c= ac
Hope I could help !
Enter an algebraic expression for the word expression.

Step-by-step explanation:
If g(x)=1-3/4x find the values of g(0), and -5·g(4)-1
If h(x)=|1-7x| find the values of h(1), and 23-h(9)
If f(x)=8-5x find the values of f(4c), and f(4p+3)
Step-by-step explanation:
g(0)= 1
g(5)= 1-3/20 = 17/20
-5.g(4)-1 =-5. (13/16) -1 = -65/16 -1= (-65-16)/16= -81/16
A student used the proportion n/100 = 5/26 to find 5% of 26. What did the student do wrong?
Given:
A student used the proportion [tex]\dfrac{n}{100}=\dfrac{5}{26}[/tex] to find 5% of 26.
To find:
The student's mistake.
Solution:
Let 5% of 26 be n. Then,
[tex]n=\dfrac{5}{100}\times 26[/tex]
On dividing both sides by 26, we get
[tex]\dfrac{n}{26}=\dfrac{5}{100}[/tex]
So, the proportion used by the student was incorrect. The denominators of the proportion are interchanged.
Solve 5x-3y =1,
3x-y=5.
Answer:
Below in bold.
Step-by-step explanation:
5x - 3y = 1
3x- y = 5 Multiply this equation by -3:
-9x + 3y = -15 Now add this equation to the first equation:
-4x = -14
x = -14/-4 = 3.5.
Now substitute for x in equation 1:
5(3.5) - 3y = 1
-3y = 1 - 17.5
-3y = -16.5
y = 5.5.

How many solutions do the TWO equations have?
15y + 12x = 18 5y + 4x = 6
==========================
2x+ 3y= 12 -6y= 4x-24
^^^ SEPERATE EQUATIONS
Answer:
Below.
Step-by-step explanation:
15y + 12x = 18
5y + 4x = 6
The second equations is the first times 3 so they are basically the same.
Infinite Solutions.
2x+ 3y= 12
-6y= 4x-24 Rearranging the second equation:
-4x - 6y = -24 Multiplying the first equation by 2:
4x + 6y = 24
- we see that the last equation is -1 * previous equation.
So there are infinite solutions.

Can someone tell me the answer to this and explain how to do it?
answer:
-2x + 9 or -2 which is what the question asks
step-by-step explanation:
we have to combine like terms which means terms that are similarin this, only 5x and -7x are like terms since both have x with them9 will stay the same since it does not have a like term5x + 9 + (-7x) = __x + 9
-2x + 9
therefore, -2 goes in the blankNeed help on this.. The first one that answer it first correctly gets a BRANLIST
Answer: The answer is C) J' (3,-1), K' (1,-4)
Step-by-step explanation: First, you need to find the location of J, which is located in Quadrant III. You go left 3, and go down 1, making the coordinates of J (-3,-1). Next, you need to find the location of K, which is also located in (-1, -4).
So, the question asks, "What are the coordinates of J' and K' after JK is reflected across the y-axis?"-- Well, first, which line is the x-axis, and which line is the y-axis?
The x-axis is the line that is horizontal(Across) while the y-axis is the line that is vertical( Up and Down).
So you bring J and Ks coordinated over the y-axis to Quadrant IV(4). You already know their original coordinates, so you place the as you would in the picture above, except that the line would be reflected.

Eli claims that the product of 6 Superscript 5 and 5 Superscript negative 3 is 6 squared. Which explains whether Eli is correct?
Eli is correct. He added 5 + (negative 3) to find the exponent of 2.
Eli is incorrect. He added the exponents instead of subtracting them.
Eli is incorrect. He subtracted the exponents instead of adding them.
Eli is incorrect. He added the exponents even though the bases are not the same.
Answer:
d
Step-by-step explanation:
Eli is incorrect because he added the exponents even though the bases are not the same.
Option D is the correct answer.
What is an expression?An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the like terms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example:
1 + 3x + 4y = 7 is an expression.
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
[tex]6^5[/tex] x [tex]5^{-3}[/tex] = 6²
Now,
Simplifying the expression.
= [tex]6^5 \times 5^{-3}[/tex]
= [tex]\frac{6^5}{5^3}[/tex]
We see that,
6² is when we add the exponents even if the base is not the same.
We can not add the exponent if the base is not the same.
Thus,
Eli is incorrect because he added the exponents even though the bases are not the same.

Sometimes you need to use FOIL, in order to simplify a radical expression,
Multiplying binomial expressions is very similar to multiplying binomial radicals
Examples:
Answer:
c) ([tex](6-\sqrt{12} )(6+\sqrt{12} ) = 24[/tex]
d) ([tex](3+\sqrt{8} )(3-\sqrt{8} ) = 1[/tex]

Step(i):-
Given that the binomial expression
([tex](6-\sqrt{12} )(6+\sqrt{12} )[/tex]
Multiply
( 36 + 6√12 -6√12 -(√12)²)
= ( 36 -12)
= 24
c) ([tex](6-\sqrt{12} )(6+\sqrt{12} ) = 24[/tex]
Step(ii):-
Given that the binomial expression

Answer:
x + 37 = 90
Step-by-step explanation:
Since complementary angles add up to 90 degrees, we would need to add 37 and x to equal 90 degrees. Therefore, x + 37 equals 90 degrees. As for solving, subtract 37 from both sides and you are left with x = 53.
Wanda has three times more shirts than her brother, Will. The equation a = 3b, where a represents the number of shirts Wanda has, and b represents the number of shirts Will has, shows this relationship. If Wanda has 24 shirts, how many shirts does Will have?
Answer:
8 shirts
Step-by-step explanation:
Given the equation a = 3b, where
a = the number of shirts Wanda has
b = the number of shirts Wanda's brother (Will) has
Hence if Wanda has 24 shirts then
24 = 3b
Divide both sides by 3
24/3 = b
b = 8 shirts
Will has 8 shirts.
Answer:
8 shirts

You take a 200 milligram dosage of aspirin. During each subsequent hour, the amount of medication in your bloodstream decreases by about 35% each hour. What level of aspirin (mg) will be in your bloodstream in 4 hours. NEED ANSWER URGENT!!!
Answer: The level of aspirin (mg) will be in your bloodstream in 4 hours = 35.70 mg.
Step-by-step explanation:
If the amount is decreasing by r%, then the final amount is given by :-
[tex]A=P(1-r)^t[/tex]
, where P = initial value , t= time
Given: P= 200 milligram, r= 35% = 0.35, t= 4 hours
The level of aspirin (mg) will be in your bloodstream in 4 hours = [tex]200(1-0.35)^4[/tex]
[tex]=200(0.65)^4\\\\=200\times 0.17850625\\\\=35.70125\approx35.70 \ mg[/tex]
Hence, the level of aspirin (mg) will be in your bloodstream in 4 hours = 35.70 mg.
Find the area of the shaded part (π=22/7)
Answer:
42cm square
Step-by-step explanation:
Frist find the area of the square. 14*14
Then find the Area of the circle.- (radius) one side of the square is the diameter so, diameter divided by 2 - 14/2=7
After that subtract the area of circle from the area of the square.
Answer:
first we find the area of the square.
area of square=side²
area of square =14²
area of square=196cm²
area of circle=pi×radius²
radius=14/2=7
area of circle=22/7×(7)²
area of circle =22/7×49
area of circle =154cm²
area of shaded region=area of square - area of circle
area of shaded= 196cm²-154cm²
area of shaded=42cm²
