The simplified expression of (3x – 5 – 7x²) – (–2 + 6x² – 5x) is

-x² + 8x - 3

To subtract polynomials. Specifically, we will solve the expression

(3x - 5 - 7x²) - (-2 + 6x² - 5x) step by step using the rules of polynomial subtraction.

To subtract polynomials, we need to combine like terms and simplify the expression.

Step 1: Distribute the negative sign in the second parentheses:

(3x - 5 - 7x²) + (2 - 6x² + 5x)

Step 2: Now, group the like terms together. Like terms have the same variables raised to the same powers:

(3x + 5x) + (-7x² + 6x²) + (-5 + 2)

Step 3: Combine the like terms:

8x - x² - 3

So, the final simplified expression after subtracting the polynomials is:

-x² + 8x - 3

1. First, we distribute the negative sign by changing the signs of all the terms in the second parentheses.

2. Next, we group the like terms together, which means combining the terms with the same variable and exponent.

3. Finally, we combine the coefficients of the like terms to obtain the simplified polynomial expression.

Answer:

m<1=74

m<2=37

Step-by-step explanation:

m<2 is the same as the other angle, 37 degrees. So now we need to find the other angle in the triangle.

37+37+x=180.

The total degree of a triangle is 180.

x=106

Subtract that from 180 to get m<1.

180-106=74

Step-by-step explanation:

Answer:

a constant term is a term in an algebraic expression that does not contain any variables

Therefore your answer is 43

Answer:

The constant term in the above expression is 43 as it has no variable where 3 has x variable 45 has y variable and 13 has z variable

So 43 is the constant term in the above expression

Answer:

$16.8

Step-by-step explanation:

Given data

We have the given function as

C= 1.80 + 1.5d

Let us substitute the value of d=10 in the expression

C= 1.80 + 1.5*10

C=1.80+15

C=16.8

Hence the cost of the ride for 10 miles is $16.8

Answer:

-17

Step-by-step explanation:

To get that answer, apply the slope formula

m = (y2 - y1)/(x2 - x1)

m = (-8 - (-8))/(9 - (-2))

m = (-8 + 8)/(9 + 2)

m = 0/11

m = 0

Any line with slope 0 is completely horizontal.

As a quick rule of thumb: if the y coordinates of the two points are the same, then the slope is 0 on this horizontal line.

Answer:

Rex buried 4 bones on Tuesday

Step-by-step explanation:

10 - 6 = 4. Simple as that

Hint : The product of the slopes of two lines perpendicular to each other is - 1 .

______________________________

In slope-intercept ( y = ax + b ) from of the linear equations the coefficient of x is the slope of the line.

Thus :

Slope of line a = - 14

______________________________

Suppose that the slope of line b is x according to the Hint we have :

- 14 × x = - 1

negatives simplify

14x = 1

Divide both side by 14

14x ÷ 14 = 1 ÷ 14

x = 1/14

So the slope of line b is 1/14

_____________________________

Now let's find the equation of line b by point-slope formula using the point question have us ( 2 , 6 ) :

y - y( given point ) = Slope × ( x - x ( g p ) )

y - 6 = 1/14 × ( x - 2 )

y - 6 = 1/14 x - 2/14

y - 6 = 1/14 x - 1/7

Add both sides 6

y - 6 + 6 = 1/14 x - 1/7 + 6

y = 1/14 x - 1/7 + 42/7

y = 1/14 x + 41/7

And we're done ...

Answer: To perform a geometry reflection, a line of reflection is needed; the resulting orientation of the two figures are opposite. Corresponding parts of the figures are the same distance from the line of reflection. Ordered pair rules reflect over the x-axis: (x, -y), y-axis: (-x, y), line y=x: (y, x).

Step-by-step explanation:

So we can actually simplify the exponents here. The power rule for exponents is that when multiplying, you add the exponents. So,

3 + (-3) = 0

so the number is now 4^0.

Everything by the power of 0 is equal to 1, so the answer is 1.

Answer:

y=-3x-10

Step-by-step explanation:

Hi there!

We need to find the equation of the line parallel to y=-3x+4 that has the y intercept of -10 (the point (0, -10))

Parallel lines have the same slope

The slope of y=-3x+4 is -3 (it is in the placement of where m (slope) is in y=mx+b)

So the slope of the new line parallel to y=-3x+4 is also -3

Here is the equation of that line so far:

y=-3x+b

b is a placeholder for the y intercept

However, we are given the y intercept as -10, so substitute -10 as b into the equation

y=-3x-10

There's the equation of the line parallel to y=-3x+4 with a y intercept of -10
