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

Answers

The correct answer is y=-3x-10

when a line is parallel to another line that means the slip of the lines are going to be the same and since the y-intercept of the other line was given to you, you would just put them together in one equation.

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

Hope this helps!

Find the slope of the line passing through the points (-2, -8) and (9,-8).
slope:

Answers

Answer:  0

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.

Answers

All of our equations are in slope-intercept form. Slope-intercept form is y=mx+b. m stands for the slope, and b stands for the y-intercept. Our y-intercept is 3. Therefore, we can eliminate the equations that say the y-intercept isn’t b. Next, we can find the slope. We have the points (0, 3) and (3, 2). The formula for slope is y2-y1/x2-x1. 2-3 is -1, 3-0 is 3. Our slope is -1/3. After eliminating those without the y-intercept, we have A or D. We know that the slope is -1/3, so the answer must be D.

Si Martha retira de su cuenta el 10% para los transportes del mes. ¿Cuál es el nuevo saldo de la cuenta?

Answers

Respuesta:

0,9 veces

Explicación paso a paso:

Deje que la cantidad en la cuenta de Martha se denote como x, que es la cantidad en la cuenta = x

Porcentaje retirado para transporte = 10%

El porcentaje total siempre será del 100%

Por lo tanto, si se retira el 10%, entonces; el porcentaje restante es:

Porcentaje total: porcentaje gastado en transporte

(100% - 10%) * monto en cuenta

90% * x = 0,9 * x = 0,9x

Saldo de cuenta nueva = 0.9x

Answers

Answer:

a. quadratic.

The given polynomial p(x)=4x−2x²+3 is a quadratic polynomial. The correct option is A.

What is a polynomial?

A polynomial in mathematics is an expression made up of coefficients and indeterminates and involves only the operations of multiplication, addition, subtraction, and non-negative integer exponentiation of variables.

In algebra, a polynomial function with one or more variables in which the highest-degree term is of the second degree is known as a quadratic function, a quadratic polynomial, a polynomial of degree 2, or simply a quadratic.

In the given polynomial p(x)=4x−2x²+3 it can be observed that the degree of the polynomial is 2 or the highest power of the variable is 2.

Therefore, the given polynomial p(x)=4x−2x²+3 is a quadratic polynomial. The correct option is A.

5) where 2 coins are toased find the probability of getting:
1)both the coins with some place
2)both the coins with different place
3)at least one tail
5)at the most one head

Answers

Step-by-step explanation:

Let S be the sample space

S={HH, HT, TH, TT}

n(S)= 4

A: both the coins with some place

B: both the coins with different place

C:at least one tail

D:at the most one head

1) A={TT,HH}

n(A)=2

P(G)= n(A)/n(S)

= 2/4

= 1/2

2) B ={HT, TH}

n(B) = 2

P(B) = n(B)/n(S)

= 2/4

= 1/2

3) C= {HT, TH, TT}

n(C)=3

P(C) = n(C)/n(S)

= 3/4

4). D={HT, TH}

n(D) = 2

P(D) = n(D)/n(S)

= 2/4

The equation of line a is y=−14x+3. If line b runs perpendicular to line a and passes through (2, 6), what would be the equation of line b?

Answers

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
