System of equations pls help me
Answer:
(4,4)
Step-by-step explanation:
We can solve this system of equations using the elimination method.
In order to use the elimination method there must be two variables with the same coefficient. Note that the coefficients don't have to have the same sign ( eg. 6 and -6 would work ). If there are two similar variables with similar coefficients then you can add or subtract, depending on the signs of the coefficients, the two equations "eliminating" the variable. There would then be one variable left over in which you can solve for.
For this case, both equations have 7x, one negative 7 and one positive 7. When the signs are different you add the two equations. So our first step is to add the two equations
7x - 4y = -44
+ (-7x -3y = 16 )
-----------------------
Remove parenthesis
7x -4y = -44
-7x -3y = +16
------------------
0x - 7y = -28
We are left with -7y = -28.
Because there is now only one variable, we can solve for it.
-7y = -28
divide both sides by -7
y = 4
Now we want to find the value of x. We can do this by plugging in the value of y into one of the equations and then solving for x. Note that we can plug in 4 for y into either equation and solve for x and we would get the same answer.
7x - 3y = 16
y = 4
7x - 3(4) = 16
multiply 4 and -3
7x - 12 = 16
add 12 to both sides
7x = 28
divide both sides by 7
x = 4
So x = 4 and y = 4 so the solution to the system of equations is (4,4)
simplify the equation
A line passes through the points (4, 6) and (8, 7). What is its equation in point-slope form?
Hello there! :)
First, let’s find the slope.
We can find it using this formula:
m=y2-y1/x2-x1
m=7-6/8-4
m=1/4
So the slope is 1/4.
Now, we can use the point-slope formula:
y-y1=m(x-x1)
y-6=1/4(x-1/4)
Hope it helps. :)

Find an equation of the vertical line through (4,-9)
Answer:
x = 4
Step-by-step explanation:
Whenever it asks for the equation of a vertical line all you have to do is look at the x point given to you which is 4 and make x = 4, doing this means that this certain vertical line covers all possible y values which includes -9 as well which is why the answer is x=4

The length of the base of an isosceles triangle is x. The length of a leg is 3x - 6. The perimeter of the triangle is 58. Find x.
Answer:
x = 10
Step-by-step explanation:
Perimeter of a triangle = the sum of the three sided of the triangle.
In an isosceles triangle, there are two equal sides and a base.
Perimeter = ( 3x - 6) + (3x - 6) + x
58 = 7x - 12
58 + 12 = 7x
70 = 7x
[tex]\frac{70}{7} = \frac{7x}{7}[/tex]
10 = x

Answer:
120.8
Step-by-step explanation:
The value of y from the given equation is 120.8.
The given equation is 62=y-58.8.
What is an equation?In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
The given equation can be solved as follows
Add 58.8 on both the sides of an equation, that is
62+58.8=y-58.8+58.8
⇒ y=120.8
Hence, the value of y from the given equation is 120.8.

What is "o"? will get 15 points for correct answer.
Answer:
54 Degrees
Step-by-step explanation:
We know that a triangle has to have 180 degrees in all. we also know that the bottom lines is a straight angle, so 180 degrees.
using this information, we can find n. We know that n+78 is 180, so n=102
We also know that o+102+24=180, so
o=54

A pile of newspapers in Mr. Moore’s ELA class was 17 ¾ inches high. Each consecutive week, for the next 5 weeks, the height of the pile of newspapers increases by 8 712 inches each week. What was the height, in inches , of the pile after 3 weeks? Step by step plz
Answer:
43 1/2
Step-by-step explanation:
answer will be:
original height plus 3 times 8 7/12 inches
3 times 8 7/12 can be done by converting the mixed number to an improper fraction:
[tex]\frac{3}{1}[/tex] · [tex]\frac{103}{12}[/tex] = [tex]\frac{103}{4}[/tex] = 25 3/4
25 3/4 added to 17 3/4 equals 42 6/4 which is 42 + 1 1/2 = 43 1/2

Why is this wrong?? Trying to do test corrections
Answer:
See answer below
Step-by-step explanation:
y = one time fee
35x = hourly rate( hours worked)
35x + y = $190
y = - 35x = 190
$35 per hours × hours work and you did not used the total cost $190
Next time rewrite the sentence and translate into an equation.
The customers service charges = one-time fee + hourly rate$ ( hours worked)
190 = y + 35(x) point slope form
- 35x + 190 = y
1) 6p + 12 - 2 = 8p + 4
6p + 12 - 2 = 8p + 4
6p + 10 = 8p + 4
6p - 8p = 4 - 10
-2p = -6
2p = 6
p = 3
Answer:
p = 3
Step-by-step explanation:
First, simplify. Combine like terms. Like terms are terms with the same variable as well as same amount of said variable:
6p + (12 - 2) = 8p + 4
6p + (10) = 8p + 4
Isolate the variable, p. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS. PEMDAS is the order of operations, and stands for:
Parenthesis
Exponents (& roots)
Multiplications
Divisions
Addition
Subtraction
First, subtract 8p and 10 from both sides of the equation:
6p (-8p) + 10 (-10) = 8p (-8p) + 4 (-10)
6p - 8p = 4 - 10
-2p = -6
Next, isolate the variable, p, by dividing -2 from both sides of the equations:
(-2p)/-2 = (-6)/-2
p = -6/-2
p = 3
3 is your answer.
