Answer:
4x-3
Step-by-step explanation:
Equation of the line that is parallel to y = 4x + 1 and contains the point (1, 1) is y = 4x - 3.
What are equation of a line that is parallel to that line?Two lines are said to be parallel if they always maintain the same distance apart. If two lines are drawn so that they could extend into infinity without ever meeting each other, these lines are called parallel. Parallel lines are also called Equidistant lines.
Given
Equation of line y = 4x + 1
Point = (1, 1)
Equation of the line that is parallel to y = 4x + 1 is y=kx + b
Here k =4
y = 4x + b and contains the point (1,1)
Substitute the point (1,1) in y= 4x + b
⇒ 1 = 4(1) + b
⇒ 1 - 4 = b
⇒ b = -3
y = 4x + b
⇒ y = 4x - 3
Equation of the line that is parallel to y = 4x + 1 and contains the point (1, 1) is y = 4x - 3.

Step-by-step explanation:
The vertex form of the equation of a parabola is ...
y = a(x -h)² +k . . . . . . . . . vertex (h, k); scale factor 'a'
The graph shows the vertex is (h, k) = (-4, -1) and a=1. Putting these values into the form, we have ...

which fraction is the least 2/4, 5/10, 2/5, 3/4
Answer:
2/5 or the third one
Step-by-step explanation:
The first two are 1/2 after they are simplified and the second two are just below or just above one half, the last one is above and the third one is below.
Answer:
2/5
Step-by-step explanation:
Convert all fractions to have a common denominator
4, 10, and 5 can all be multiplied to equal 20
As a result, we will use 20 for the common denominator
What multiplied by 4 equals 20? 5 × 4 = 20
What multiplied by 10 equals 20? 2 × 10 = 20
What multiplied by 5 equals 20? 4 × 5 = 20
If we multiply this to the denominator, we must also multiply the same number to the numerator
Starting from left to right:
2 × 5 / 4 × 5 = 10/20
5 × 2 / 10 × 2 = 10/20
2 × 4 / 5 × 4 = 8/20
3 × 5 / 4 × 5 = 15/20
Compare: 10/20, 10/20, 8/20, 15/20
Which fraction has the smallest numerator?
8/20 as 8 is less than 15 and 10
Which fraction was 8/20? Check back to our work.
8/20 = 2/5
2/5 is the least

Step-by-step explanation:
The length of a rectangle is 3m less than twice the width, and the area of the rectangle is 65m^2 . Find the dimensions of the rectangle.
W
L=2w-3
Area=(L×w)
65=[(2w-3)×w]
65 =(2w²-3w)
65=2w²-3w
2w²-3w-65=0
by using the quadratic equation
you'll get 2 values in which one will be negative
Obviously a length can't be negative so you take the positive.
w=6.5m
L=2(6.5)-3
=10m

Solve the triangle. A = 46°, a = 31, b = 27
Answer:
A=46 degrees, B=33.4 degrees, C=100.6 degrees
a=34, b=27, c=48.2
Step-by-step explanation:
(a/sin(A)) = (b/sin(B)) = (c/sin(C))
we are given
(34/sin(46)) = (27/sin(B))
34sin(B) = 26sin(46)
34sin(B) = 18.702834809
sin(B) = 0.550083377
note use inverse sin function to find angle B
B = 33.372733167 approx 33.4 degrees then
C = 180 - (46 + 33.4) = 100.6
Then, (b/sin(B)) = (c/sin(C))
27/0.550083377 = c/0.982935349
0.550083377 * c = 27 * 0.982935349
0.550083377 * c = 26.539254427
c = 48.245876056 approx 48.2 .
Lastly, you get: A=46 degrees, B=33.4 degrees, C=100.6 degrees
a=34, b=27, c=48.2

complete question
study by Allstate Insurance Co. finds that 82% of teenagers have used cell phones while driving ( The Wall Street Journal , May 5, 2010). In October 2010, Massachusetts enacted a law that forbids cell phone use by drivers under the age of 18. A policy analyst would like to determine whether the law has decreased the proportion of drivers under the age of 18 who use a cell phone.a. State the null and the alternative hypotheses to test the policy analyst’s objective.
b. Suppose a sample of 200 drivers under the age of 18 results in 150 who still use a cell phone while driving. What is the value of the test statistic? What is the p-value?c. At α = 0.05 has the law been effective?
d. Repeat this exercise using the critical value approach with α = 0.05
Answer:
1. H0: p>=0.82
H1: p<0.82
2. z test statistic = -2.5767
3. the law has been effective
4. the null is rejected, the law has been effective
Step-by-step explanation:
1. hypothesis formulation
H0: p>= 0.82
H1: p< 0.82
2. p = 82% = 0.82
estimated p^ = x/n = 150/200 = 0.75
standard error calculation:
= √0.82(1-0.82)/200
= √0.82x0.18/200
= √0.02716615
Z test statistic calculation:
= 0.75-0.82/0.02716615
= -2.5767
3. this test is 1 tailed
the p-value using a p value calculator is = 0.004983
0.004983 < 0.05 so we Reject null and conclude that the law has been effective.
4. we Reject null at 0.05 if z is less than -1.645.
-2.5767<-1.645 so we Reject H0 and conclude law has been effective and there is a decrease in drivers under this age who use cell phones

Each cube has 2-inch-long edges. What is the volume of the figure?
Answer:
8 inches (to the third power)
Step-by-step explanation:
The formula for the volume of a cube is V = s^3 (side to the third power)
So if we plug in '2' then we get our volume

Which of the following cannot be the side lengths of a triangle?
10, 12, 18
9, 9, 10
3, 11, 15
10, 15, 20
Answer:
3, 11, 15
Step-by-step explanation:
The two shorter sides add up to 14, which is smaller than 15, therefore making the triangle impossible as the sum of the two smaller sides have to be larger than the longest side
