Step-by-step explanation:
Solve the simultaneous equations y= 2x
y=x^2-4x+8
Answer:
x = 4
Step-by-step explanation:
y = 2x , y = x^2 -4x +8
=> 2x = x^2 - 4x + 8
6x - x^2 - 8 = 0
(-x^2 + 2.3x - 3^2 ) -1 = 0
( -x-3)^2 - 1= 0
(-x-3)^2 = -1
(-x-3)^2 = (-1)^2
-x - 3 = 1
x = 4
2(x + 1) = 2
what’s the solution ?
Answer:
x = 0
Step-by-step explanation:
2(x + 1) = 2
x + 1 = 2 ÷ 2
x + 1 = 1
x = 1 - 1
x = 0
Answer:
x = 0
Step-by-step explanation:
2(x+1)=2
2x + 2 = 2
2x = 2-2 = 0
x = 0

.3(3x+7)= 9x +21 help please
that is true
Step-by-step explanation:
3×3x = 9x
3×7= 21
So 9x + 21
because you cant add a variable to a number that doesnt have the same variablem
Answer:
All real numbers make this equation true, so it is true.
Step-by-step explanation:
3(3x+7)=9x+21 if I were to input 3 as x on both sides, it would equal 48 on each side.
It essentially becomes 3(9+7)=27+21
then 3(16)=48
48+48
This is true for all variables, so the equation must be true
2(2 + 2) = 4(1 − 8)

solve the equation 7+2 |2x+1| =15
Answer:
I believe the answer is X=2.5
Step-by-step explanation:
7+2=9
so now we have to find what X would be so we can do the second equation
So we know that the second equation must equal 6 because 9+6=15
So now we experiment with different numbers for X
if we did 2, the new equation would be 2x2+1 which is 5, too low
if we did 3, the new equation would be 2x3+1 which is 7, too high
So we need something in the middle
in the middle of 5 and 7 is 6 which is the number we need
so to get 6 we need something in between 2 and 3, which in 2.5

For Beatrix's latest art installation,
she has fixed a 2 x 2 square sheet of steel to a wall.
She has two 1 x 2 magnetic tiles, both which she
attaches to the steel sheet, in any orientation, so
that none of the sheet is visible and the line
separating the two tiles cannot be seen. As shown
alongside, one tile has one black cell and one grey
cell; the other tile has one black cell and one spotted
cell.
How many different looking 2 x 2 installations can
Beatrix obtain?
Answer:
4
Step-by-step explanation:
there are 2 combinations given already, and a 1 x 2 tile is half of the steel square, so you could also have black+black and grey+spots so add all combinations together and you get 4 combos!

Jim rented a truck for one day. There was a base fee of $15.95, and there was an additional charge of 78 cents for each mile driven. Jim had to pay $186.77 when he returned the truck. For how many miles did he drive the truck?
Answer:
219 miles.
Step-by-step explanation:
Jim paid $186.77 in total.
The base fee was $15.95
$186.77 - $15.95 = $170.82
The base fee was taken care of, the rest of the money was spent on the number of miles he drove.
For each mile he needs to pay 78 cents (Aka 0.78).
$170.82 ÷ 0.78 = 219
Jim drove 219 miles.

What is the value of y?
A. 72°
B. 36°
C. 54°
D. 108°
Answer:
C. y = 54°Step-by-step explanation:
y + y + 72 = 180
2y = 180 - 72
y = 108/2
y = 54°
Find X and Y and show please show calculations
Answer:
Y = 90
X = 52
Step-by-step explanation:
Y is on a straight line. The sum of the angles on a straight line is 180.
The only other angle (that is marked) on this straight line, is a 90 degree one. So, <y + 90 = 180.
<y = 90.
Now <x + 38 = 90
so, x = 52
Answer:
Y = 90
X = 52

You go to a pizza place and order 4 medium pizzas and an order of breadsticks. The breadsticks cost $4.30
The total bill was $. Write and solve an equation to find the price of each pizza.
find the values of x,y,and z. The diagram is not to scale
Answer:
x+63°+36°=180°(angle sum property in first triangle)
x+99°=180°
x=180°-99°
x=81°
x + z=180
81°+z=180°
z=180°-81°
z=99°
z+13°+y=180(angle sum property in second triangle)
99°+13°+y=180
112°+y=180°
y=180°-112°
y=68°
therefore, x=81° z=99° y=68°

Use your knowledge of the Triangle Sum Theory to solve for x. Then solve for ∠ L.
help plss
Answer:
X= 15
K=45
Step-by-step explanation:
The Triangle Sum Theory means that every interior angle of a triangle sums up to 180. My first approach was to put 169 as x but that isn’t correct. That is because a triangle’s smallest angles have to add up to be more than the biggest angle. Ex (10, 5, 7 that is a triangle because the sum of 5+7 is more than 10) So as you can see there are x’s next to the other numbers. That is because x needs to be able to multiply with the other numbers and stand on it’s own and add up to 180. So this would be the equation: X+8•X+3•X=180. You should find that 15 makes everything add up to 180. Now knowing x is 15 now we know that 3x is equal to 45. So k=45 That is how you solve this tricky question. Hope this helps! ❤️
What does x equal in -7=-1+x/3
Hello! :)
To solve your equation, we will first simplify both sides of the equation
-7 = -1 + x/3
-7 = -1 + 1/3x
-7 = 1/3x - 1
Next, we will flip the equation
1/3x - 1 = -7
Third, we will add 1 to both sides
1/3x - 1 + 1 = -7 + 1
1/3x = -6
Last, we will Multiply both sides by 3
3 * (1/3x) = (3) * (-6)
x = -18 (ANSWER)
That means -18 is you answer

For h(x) = x3 + 2x, find h(4).
Answer:
h(4) = (4)3+2(4) = 20
Step-by-step explanation:
First you input 4 wherever there is an x then you restated the equation with 4 substituted in as x next solve
The value of h(4) is 72.
Important information:
The given function is [tex]h(x)=x^3+2x[/tex].Value of function:Substitute [tex]x=4[/tex] in the given function.
[tex]h(4)=(4)^3+2(4)[/tex]

Ms. Franco has 64 pencils and 48 erasers. She wants to put an equal number of pencils and erasers into boxes for her students. What is the GREATEST number of pencils or erasers Ms. Franco can put in each box?
answer: 16
but why is the answer 16
Answer:
16
Step-by-step explanation:
Given that:
Number of pencils = 64
Number of erasers = 48
To obtain the GREATEST number of pencils or erasers Ms. Franco can put in each box, the we find the greatest common factor of both numbers ; 64, 48
_____64 ___48
__2__32___24
__2__16___12
__2__8___ 6
__2__4___3
No number can divide both numbers simultaneously further.
Hence, greatest common factor :
(2 * 2 * 2 * 2) = 16
