Answer:
it's 4
Step-by-step explanation:
Answer:
y = x + 5
Step-by-step explanation:
Perpendicularity: Slope is the opposite reciprocal. In this case with it being -1 aka -1/1, the slope will be 1 aka 1/1
Find the opposite reciprocal of the slope
m = -1 = -1/1
so,
m⊥ = 1 as the opposite reciprocal is 1/1
2 - Plug the new slope into y = mx + b
y = mx + b
y = 1x + b
y = x + b
3 - Plug the point values in replacing x and y to get alone and solve for the y intercept, b.
y = x + b
-4 = -9 + b
+9 +9
5 = b
4 - Plug into the values into y = mx + b all together
y = mx + b
y = 1x + 5
y = x + 5
Hope this helps :)
Scientific notation consists of a coefficient (here 5.14) multiplied by 10 raised to an exponent (here 5). To convert to a real number, start with the base and multiply by 5 tens like this: 5.14 × 10 × 10 × 10 × 10 × 10 = 514000.0. Multiplying by tens is easy: one simply moves the decimal point in the base (5.14) 5 places to the right, adding extra zeroes as needed.

Here we wish to write the number 0.000345 as a coefficient times 10 raised to an exponent. To convert to scientific notation, start by moving the decimal place in the number until you have a coefficient between 1 and 10; here it is 3.45. The number of places to the left that you had to move the decimal point is the exponent. Here, we had to move the decimal 4 places to the right, so the exponent is -4.
Answer:
Undefined
Step-by-step explanation:
The formula for slope is 
So use the x's and y's from the given points to solve for the slope
(10, -6) (10, -6)
The slope for this line would be undefined because a number cannot be divided by 0
Answer:
x³+3x²+4x+12
Step-by-step explanation:
you are going to write both equations and distribute. if there are like terms, combine them and then put it order.
(x + 3) × (x² + 4)
x³ + 4x + 3x² + 12
when putting in order, you want the highest power to the left and then the lowest power to the right.
so
x³+3x²+4x+12
