Hi!

Using y = mx + b form, where m is the slope and b is the y-intercept, we get the equation: y = -2x + 0.3

Hope this helps! :D

Answer:

$\boxed{\sf{14}}$

Step-by-step explanation:

$\boxed{\underline{\text{ORDER OF OPERATIONS:}}}$

Use the order of operations.

Note: PEMDAS or BODMAS stands for:

PEMDAS

Parentheses
Exponents
Multiply
Divide
Add
Subtract

BODMAS

Brackets
Order
Divide
Add
Subtract

First, do parentheses.

3+6*(5+4)÷3-7

(5+4)=9

$\Longrightarrow: \sf{3+6* 9\div 3-7}$

Do multiply and divide.

6*9=54

54/3=18

Then, rewrite the problem down.

$\Longrightarrow: \sf{3+18-7}$

Add.

$\sf{3+18=21}$

$\sf{21-7=\boxed{\sf{14}}$

$\Longrightarrow: \boxed{\sf{14}}$

Therefore, the correct answer is "C. 14".

I hope this helps, let me know if you have any questions.

X^2-12x+36=0 X= Solve for x

solong [7]

Answer:

Step-by-step explanation:

X^2-12x+36=0

X^2 - 8x - 4x + 36 = 0

(x^2 -8x) - (4x - 36) = 0

x(x - 8) - 4(x - 8) = 0

(x - 4)(x - 8) = 0

:- x - 4 = 0 or x - 8 = 0

x = 4 or x = 8

angle 1 and angle 2 are vertical angles. if the measure of angle 1 is (6x+11)° and measure of angle 2 is (10x-9)° find measure o

Svetradugi [14.3K]

Answer:

Angle 1 = 41°

Step-by-step explanation:

Since they are both vertical angles

(6x+11)° = (10x-9)°

6x - 10x = -9 - 11

-4x = -20

4x = 20

x= 5.

Therefore,

Angle 1 = 6(5) + 11

Angle 1 = 30 + 11

Angle 1 = 41°

Alto earned $ 225 and Sheryl earned $ 250.

Given that Alto and Sheryl both worked hard over the summer, and together they earned a total of $ 475, and Sheryl earned $ 25 more than Alto, the following calculation must be performed to determine how much each one earned:

S = A + 25
A = A
A + 25 + A = 475
2A = 475 - 25
A = 450/2
A = 225
S = 225 + 25 = 250

Therefore, Alto earned $ 225 and Sheryl earned $ 250.
