Step-by-step explanation:
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?
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 ...

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

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.

x = 9
CB = DB = 61
Step-by-step explanation:
∠CAB = ∠DAB
So, DB = CB {Sides opposite to equal angles are equal}
6x +7 = 3x+ 34
Subtract 7 from both sides.
6x = 3x + 34 - 7
6x = 3x + 27
Subtract 3x from both sides.
6x - 3x = 27
3x = 27
Divide both sides by 3
x = 27/3
x = 9
DB = 6x +7
= 6*9 + 7
= 54 + 7
DB = 61
CB = 3x + 34
= 3*9 + 34
= 27 + 34
CB = 61

Question 7(Multiple Choice Worth 1 points) (08.02 LC) Eva conducted a survey to find out the amount of time high schoolers spend surfing the Internet. From the data collected, the range of time spent was 3 hours. What does this range say about the data? The quotient between the greatest amount of time and the least amount of time spent surfing the Internet is 3 hours. The difference between the greatest amount of time and the least amount of time spent surfing the Internet is 3 hours. All the students surveyed spend exactly 3 hours surfing the Internet. All the students surveyed spend an average of 3 hours surfing the Internet.
Answer:
The answer is "Option B".
Step-by-step explanation:
The difference between most time and also the least spending time on Internet surfing is 3 hours. Since we do not have charts for tables etc., only 3 can be used we need. A range is defined as the difference between the largest and the smallest amounts. The range between both the largest as well as the smallest is unique. In this reply, it tells us that the gap between most time and the fewer hours invested surfing the web is 3 hours.
In option A, it is wrong since the range has nothing to do with formulas. (Of course, the dividend with a divisor results in a quotient). Only subtraction and not division may be achieved.In option C, when all surf for exactly one hour, it could take the largest time of 3 hours and 3 hours, the last time. Add it into the equation and the range of the data present would've been 0.In option D, It is erroneous even as the range is not the mean, and the mean seems to be the average. We search for both the range, not the mean.The answer is B
The difference between the greatest amount of time and the least amount of time spent surfing the Internet is 3 hours.
This answer is proven 100% correct.

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.

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

Answer:
$14
Step-by-step explanation:
x = price of scarf 1
y = price of scarf 2
together they cost $25
x + y = 25
one scarf costs $3 more than the other
x = y + 3
now we use that in the first equation again
y+3 + y = 25
2y +3 = 25
2y = 22
y = $11
=> x = y +3 = 11 + 3 = $14

which expression is equivalent to (4 square root 5 to the power of 3) to the power of 1/2
Find the slope of the line passing through the points (-2, -8) and (9,-8).
slope:
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.

find the angle measures given the figure is a rhombus.
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
