a line is drawn perpendicular to y=(1/2)x+6 and passes through the points (b,1) and (-3,2). what is the value of b
Answer:
[tex]{ \tt{y = \frac{1}{2} x + 6}} \\ [/tex]
- If two lines areperpendicular, their gradients have a relation below;
[tex]{ \tt{m_{1} \times m _{2} = - 1 }} \\ [/tex]
- Therefore, gradient for points (b, 1) and (-3, 2);
[tex]{ \tt{ \frac{1}{2} \times m _{2} = - 1}} \\ \\ { \tt{m = - 2}}[/tex]
- Therefore:
[tex]{ \tt{ - 2 = \frac{2 - 1}{ - 3 - b} }} \\ \\ { \tt{ - 2( - 3 - b) = 1}} \\ \\ { \tt{6 + 2b = 1}} \\ { \tt{2b = - 5}} \\ { \tt{b = - \frac{5}{2} }}[/tex]
Which of the following does NOT represent the distance a car travels when going 75 miles per hour
PLS HELP I WILL MARK BRAINLIEST
The answer is D which does not represent the distance a car travels when going 75 miles per hour. 1 Hour and 15mins a car travels 93 3/4 miles
How to calculate distance?Use the formula d = st, or distance equals speed times time, to find the distance. Since both represent a certain amount of distance per unit of time, such as miles per hour or kilometers per hour, rate and speed are comparable. If speed s and rate r are equal, then r = s = d/t.Speed is calculated as Distance x Time.Time is determined using the formula Time = DistancexSpeed.Distance is calculated as Distance = Speed x Time.Distance divided by time equals speed. Simply explained, it would look like this after traveling 60 kilometers in one hour: Distance (60 kilometers) divided by time (1 hour) equals 60 km/h.To learn more about Distance refer to:

2 Sue is x years old. She is over 2.
Ben is twice as old as Sue.
Ceri is 4 years older than Sue.
The total of their three ages is less than 28.
a Write this information as an inequality.
b What age could Sue be?
c What are the corresponding ages of Ben and Ceri?
a. x < 2
b. Sue's age = 4
c. Ben's age = 8 and Ceri's age = 16
How to solve Ages problems ?
- If the present age is y, then n times the present age = ny.
- If the present age is x, then age n years later/hence = x + n.
According question,
Sue = x
She is over 2, so Sue = x+2
Ben age is twice as old as Sue,
so, Ben = 2(x+2)
Ceri is 4 years older than Sue.
so, Ceri = 4(x + 2)
The eq. will form as,
(x+2) + 2(x+2) +4(x+2) < 28
=> x + 2 + 2x+ 4 + 4x + 8 < 28
=> 7x < 28 - 14
=> 7x < 14
=> x < 2
Sue age = x + 2 = 2 + 2 = 4
Ben's age = 2( x + 2) = 2(2 + 2) = 8
Ceri's age = 4(x + 2) = 4(2 + 2) = 16
Therefore, the answer of a. x < 2
b. Sue's age = 4
c. Ben's age = 8 and Ceri's age = 16

-3x-3y=3 y=-5x-17 its solving a question using subsitution
The required solutions are x = - 4 and y = 3 to the given linear system of equations. which are determined by the substitution method.
The linear system of equations is given in the question
-3x - 3y = 3 ....(i)
y = -5x - 17 ....(ii)
Substitute the value of equation (ii) in equation (i),
-3x - 3(-5x - 17) = 3
-3x - 3 ×-5x - 17 × -3 = 3
-3x + 15x + 54 = 3
Rearrange the terms likewise and apply the arithmetic operation,
12x + 51 = 3
12x = -48
x = -48/12
x = - 4
Substitute the value of x = - 4 in equation (ii), and solve for y
y = -5(-4) - 17
y = 20 - 17
y = 3
Thus, the required solutions are x = - 4 and y = 3 to the given linear system of equations.

2) The midpoint M of line segment AB has coordinates (-3, 4). If A is the origin (0.0),
what are the coordinates of point B? (The use of the accompanying grid is optional)
Step-by-step explanation:
the coordinates of the midpoint between points A and B are
((xa + xb)/2, (ya + yb)/2)
in our case that is (-3, 4).
xa = 0
ya = 0
so we get
-3 = (0 + xb)/2
-6 = 0 + xb = xb
4 = (0 + yb)/2
8 = 0 + yb = yb
B = (-6, 8)

For the function f(x) and the given domain: {-1, 0, 1}, the range is {-8, -1, 6}
What is the range of the function?
For a function y = f(x), we define the domain as the set of the inputs (possible values of x) and the range as the set of the outputs (possible values of y).
In this case, the function is:
y = 7x - 1
And the domain is: {-1, 0, 1}
By evaluating ni the values of the domain, we will get the values of the range.

What is transformation in graphs?The graph's curve "moves to the left/right/up/down," "it expands or compresses," or "it reflects" when a function is transformed. For instance, simply advancing the graph of the function g(x) = x2 by 3 units will yield the graph of f(x) = x2 + 3. Function transformations are very useful for graphing the functions by simply moving, expanding, compressing, or reflecting the curve, as opposed to having to start from scratch with the graphing.
A function transformation "moves," "resizes," or "reflects" the parent function's graph, depending on the case. Function transformations can be broadly divided into three categories:

Margot goes to the store to buy curtains without measuring the lenght of her windows. she guesses the windows are 36 inches in length. when she gets home she measures and finds they are 40 inches in length.what is the percent error of her guess.
Answer:
The percent error is 10%
Step-by-step explanation:
The lengh of the windows are 40 inches, which is the 100% of the lengh.
What you have to do is to put 40 and 100 in a proportion with her guess, which is 36:
40 / 100 = 36 / x
so you do: (100 x 36) / 40 = 90%
This means that the percent error of her guess is 100% - 90% = 10%

Given f(x) = x² - 10x + k, and the remainder when f(x) is divided by x + 2 is

The value of k is [tex]8[/tex]
Given that f(x) = [tex]x^{2} -10x+k[/tex] and when it is divided by [tex]x+2[/tex] it gives us the remainder as [tex]32[/tex]
now we know that Divident=Divisor*quotient+remainder...(1)
Now since the quotient is [tex]x+2[/tex]remainder [tex]32[/tex] and we don't know the divisor while the divident is [tex]x^{2} - 10x + k[/tex]
hence putting the values of divident, divisor, quotient, and the remainder in (1)
we get
[tex]x^{2} - 10x + k=divisor*(x+2)+32[/tex]
using the remainder theorem put [tex]x+2=0[/tex] which gives us the value of x as [tex]-2[/tex]
Now put [tex]x=-2[/tex] in f(x) that is find the value of f(x) at [tex]x=-2[/tex] that is find[tex]f(-2)[/tex]and put that value equal to the remainder which is [tex]32[/tex] in our case
Hence according to the remainder theorem;
[tex]f(-2)=(-2)^2-10(-2)+k=32[/tex]
[tex]4+20+k=32[/tex]
[tex]24+k=32[/tex]

What is the distance between two points?The distance between two points is defined as the length of the line segment between two places represents their distance. Most significantly, segments that have the same length are referred to as congruent segments and the distance between two places is always positive.
The formula of distance between two points is P(x₁, y₁) and Q(x₂, y₂) is given by: d (P, Q) = √ (x₂ – x₁)² + (y₂ – y₁) ².
We have been given as C is the point (1, -2)
The point D lies in the second quadrant and has coordinates (x, 5)
The Length of CD is the square root of 53 units.
Length of CD = √ (x – 1)² + (5 – (-2)) ²
√(53) = √ (x – 1)² + (5 – (-2))²
53 = (x – 1)² + (5 + 2)²
53 = x² - 2x + 1 + 49
x² - 2x -3 = 0
x = 3, -1
Since D lies in the second quadrant, so x-coordinate will be negative.
Therefore, the value of x would be -1.
