x = -15
Step-by-step explanation:
1) Four times sum of a number and 10
4(x + 10)
2) is equal to 100 added to 8 times the number
4(x+10) = 8x + 100
x + 10 = 2x + 25
-15 = x

Hi! I'm happy to help!
A square root, means:
√x=y
This means that:
x=y·y=√x·√x
When we have the square button, it causes everything to be multiplied by itself once.
√x²=x
Due to the fact that the squared symbol is outside of the parenthesis, it causes both the square toot of 2, and the square root of 3, to be squared.
Now that we know this, √2², and √3²= 2, and 3.
This is why we get 2+3.
2+3=5, which is pretty self explanatory.
I hope this was helpful, keep learning! :D
How do I work this out (don’t tell me the answer) quickest reply gets brainiest
Answer:
2/7 divided by 3/4
So we can't divide fractions but what we can do is multiply them.
The First step is to do KCF (Keep, Change, Flip)
So It will be 2/7 TIMES 4/3. Keep 2/7 change the division sign to multiplication sign and flip 3/4 to 4/3. Now Multiply normally.
I hope this helps you find the correct answer <3

A coffee shop uses the formula P=C+1/2S to calcuate the number of loyalty points a customer has earned after buying C coffees and S sandwiches.
a. If Pete has 32 loyalty points after buying 23 coffees, then how many sandwiches has he bought?
b. If Morgan has 22 loyalty points after buying 14 sandwiches, then how many coffees has she bought?
Answer: a.) Pete bought 18 sandwiches.
b.) Morgan bought 15 coffees.
Step-by-step explanation: The formula P = C + 1/2S lets us know that sandwiches are worth half as many points as coffees.
a. If Pete has 32 loyalty points after buying 23 coffees, then how many sandwiches has he bought?
Plug in the number of points (P) and the number of coffees (C).
32 = 23 + 1/2S
subtract 23 from each side of the equation.
9 = 1/2S
Now. to solve for S, multiply each side by 2.
18 = S
Pete bought 18 Sandwiches.
b. If Morgan has 22 loyalty points after buying 14 sandwiches, then how many coffees has she bought?
The same method can be used for problem b.
Plug in the number of points (P) and the number of sandwiches (S).
22 = C + 1/2 (14)
Multiply 1/2 by 14.
22 = C + 7
To solve for C, subtract 7 from each side of the equation.
15 = C
Morgan Bought 15 coffees.

Answer:
B. Real numbers
Step-by-step explanation:
Real numbers are all numbers, rational and irrational, that could be found on a plane. This includes all positive and negative numbers, and all decimals. So, this only excludes imaginary numbers. The rest of the options exclude irrational numbers and more.

please help find the sum of all even integers from 2 to 100
Answer:
2550
Step-by-step explanation:
2 + 4 + 6 + ……… + 98 + 100
= (2×1) +(2×2) + (2×3) + ……… + (2×50)
= 2 × (1 + 2 + 3 + ………. + 50)
The sum (S) of n natural numbers is given by -
S = (n × (n + 1) )/2
Therefore,
2 × (1 + 2 + 3 + ……… + 50)
= 2 × ((50 × 51)/2)
= 2 × (2550/2)
= 2 × 1275
= 2550

write a function to repaint this. reflection across the y axis, then a translation a units to the right and b units up
Answer:
For the first one, I believe you would need to use a rotation matrix; to rotate 90º counterclockwise, the matrices would look like ; you would then multiply those out. A reflection across the x-axis would be changing the sign of f(x) (from negative to positive or positive to negative), a reflection across the y-axis would be changing the sign of x, translation a units to the right would be subtracting a from x, translation b units up would be adding b to x. Rotation of 180º about the origin would be the same format as the first matrix, except it would be cos180 and cos0 on the top and sin180 sin0 on the bottom. Reflection across the y-axis would be changing the sign of x again.
OR
1. We know that, 'Translation shifts the figure in any direction'.
As, the function f(x) is translated 'a' units to the right, the new form of function is f(x-a).
Again, the function is translated 'b' units up, the final form of the function is f(x-a)+b.
2 and 3. We know that, ' Reflection flips the image over a line'.
As the function g(x) is reflected over y-axis, the new form of the function is g(-x).
As the function h(x) is reflected over x-axis, the new form of the function is -h(x).
4 , 5 and 6. We know that, 'Rotation turns the image around a point to a certain degree'.
Let us assume the function to be a point (x,y).
As the function is rotated by 90° counterclockwise about the origin, the new function becomes ( y,-x ) i.e. R_{90}R
90
(x,y) = ( -y,x ).
As the function is rotated by 180° counterclockwise about the origin, the new function becomes ( y,-x ) i.e. R_{180}R
180
(x,y) = ( -x,-y ).
As the function is rotated by 2700° counterclockwise about the origin, the new function becomes ( y,-x ) i.e. R_{270}R
