Answer:
11x-8
Step-by-step explanation:
First you expand 3(x-2): 3x-6
3x-6+2(4x-1)
then expand 2(4x-1): 8r - 2
3x-6+8x-2
and then simplify 3x - 6 + 8x -2: 11x - 8
11x - 8
so the answer is 11x-8
During a scuba dive, Lainey descended to a point 26 feet below the ocean surface. She continued her descent at a rate of 26 feet per minute. Enter an inequality you could solve to find the number of minutes she can continue to descend if she does not want to reach a point more than 78 feet below the ocean surface. Use t to represent the variable for the minutes Lainey can continue to descend.
Answer:
t ≤ 2
Step-by-step explanation:
Given that:
Initial Position = - 26 feets (below surface)
Descent rate = 26 feets per minute
Maximum depth = 78 feets
Let t = number of minutes
Hence,
Initial position + (descent rate * number of minutes) ≤ - 78
-26 + (- 26t) ≤ - 78
-26t ≤ - 78 + 26
-26t ≤ - 52
t ≤ 52/26
t ≤ 2

Nevaeh is decorating the Christmas tree. She has 85 red bulbs, 76 green bulbs, 49 yellow bulbs, and 52 blue bulbs.
A. Does she have more red and blue bulbs or green and yellow bulbs?
B. How many light bulbs does she have in all?
Answer:
A) Red and Blue Bulbs
B) 262 lightbulbs.
Step-by-step explanation:
A) red and blue = 85+52=137
Yellow and green = 76+49=125
Answer to A is Red and Blue bulbs
Bulbs in all: We already know from A that there are 137 and 125 so 137+125 is 262.

Up on the left, up on the right
Up on the left, down on the right
Down on the left, up on the right
Down on the left, down on the right
Step-by-step explanation:
Coefficient of 3x⁴ is positive (concave upwards)
Power of x⁴ is even (both ends go upwards)
Hence the answer is Up on the left, up on the right.
Find the values of x in [0, 360°) which satisfy the
equation below.
2 cota x = -3 SC X
Given :
An equation 2cot x = -3sec x .
To Find :
the values of x in [0, 360°) which satisfy the given equation.
Solution :
Converting cot x and sec x in the form of sin x and cos x.
[tex]\dfrac{2cos \ x}{sin\ x}= \dfrac{-3}{cosx}\\\\2cos^2 x +3 sin\ x =0\\\\2( 1 - sin^2 x ) + 3sin \ x = 0 \\\\2sin^2 x -3sin\ x -2 = 0\\\\2sin^2\x -4sin\ x + sin\ x -2 = 0\\\\2sin\ x( sin\ x - 2 )+ 1( sin \ x - 2 ) = 0\\\\sin \ x = \dfrac{-1}{2} \ or\ sin \ x = 2[/tex]
Neglecting sin x = 2 because sin x cannot be greater than 1.
x = π - π/6, π + π/6
x = 5π/6 and x = 7π /6
Therefore, the values of x in [0,360°) is 5π/6 and x = 7π /6 .

Alex is trying to run a certain number of miles by the end of the month Alex is 40% of the way to achieving her goal and she already has run 12 miles how many miles is she trying to run by the end of the month
Answer:
30 miles
Step-by-step explanation:
Given that:
Alex has some target to run a certain number of miles by the end of the month.
Goal already achieved = 40% of the total goal
Number of miles already run by Alex = 12 miles
To find:
Number of miles that Alex is trying to run by the end of month?
Solution:
We have to find nothing but the goal of Alex here.
Let the number of miles that Alex is trying to run by the end of the month = [tex]x[/tex] miles
As per question statement:
40% of total number of miles to be run = 12 miles
OR
[tex]\dfrac{40}{100}\times x = 12\\\Rightarrow 40x=12\times 100\\\Rightarrow x = \dfrac{1200}{40}\\\Rightarrow \bold{x = 30\ miles}[/tex]
Total number of miles that Alex is trying to run by the end of the month = 30 miles

[tex] = > \bf \frac{x}{40} = \frac{4}{5} [/tex]
[tex] \bf = > 40 \times \frac{x}{40} = 40 \times \frac{4}{5} [/tex]
[tex] \bf = > x = 8 \times 4[/tex]

The sum of the firstnith term of series
is given by Sn = n2+ 5 n-6. Find the
general term (tn) and (+20)
Answer:
Tn = 2n+4
T20 = 44
Step-by-step explanation:
Given Sn = n²+ 5 n-6
Tn = Sn - Sn-1
Sn-1 = (n-1)² + 5(n-1) - 6
Tn = n²+ 5n-6 - ((n-1)² + 5(n-1) - 6))
Tn = n²+ 5n-6-(n²-2n+1+5n-5-6)
Tn = n²+ 5n-6-n²+2n-1-5n+5+6
Tn = 2n-7+11
Tn = 2n+4
Get the general term is 2n+4
To get the 20th term;
T20 = 2(20) + 4
T20 = 40+4
T20 = 44
Hence the 20th term of the sequence is 44

Rewrite the following equation in slope-intercept form. y - 8 = -8(x + 2)
Step-by-step explanation:
y - 8 = -8(x + 2)
y - 8 = -8x - 16
y = -8x - 8
The slope-intercept form is y = -8x - 8.
Answer:
y = -8x - 8
Step-by-step explanation:
First distribute the -8 into the parentheses
next get the the y by itself
add 8 to both sides and you get
y = -8x - 8

Write an equation in point-slope form of the line that passes through the given point and with the given slope m.
(-4,1) m=4
The equation of the line is ?
Answer:
An equation in point-slope form of the line that passes through the given point and with the given slope m = 4 will be:
[tex]y-1 = 4(x-(-4))[/tex]
Step-by-step explanation:
Given
The point = (-4, 1)m = 4Using the point-slope form of the line equation
[tex]y-y_1=m\left(x-x_1\right)[/tex]
here:
m = slope(x₁, y₁) = pointsubstituting the values m = 4 and the point (-4, 1) in the point-slope form of the line equation
[tex]y-y_1=m\left(x-x_1\right)[/tex]
[tex]y-1 = 4(x-(-4))[/tex]
Thus,
An equation in point-slope form of the line that passes through the given point and with the given slope m = 4 will be:
[tex]y-1 = 4(x-(-4))[/tex]
Note: It can further be simplified
[tex]y-1=4\left(x+4\right)[/tex]
Add 1 to both sides
[tex]y-1+1=4\left(x+4\right)+1[/tex]
[tex]y=4x+17[/tex]

Rachel's biscuits require 0.75 cup of milk for 1 batch. Use dimensional analysis to convert this amount into liters. Use the conversion factors 1 cup/0.5 pints to convert cups into pints, 1 pint/0.5 quart to convert pintos to quarts, and 1 quart/0.94 liter to convert quarts to liters. Use the correct number of significant digits to give your answer
Answer:
0.75 cup = 0.1763 liters
Step-by-step explanation:
From the question:
Using the conversion factors given in question
We are converting
0.75 cup to liters
Step 1
Convert cups to pint
1 cup = 0.5 pints
0.75 cup = x pints
x = 0.75 × 0.5 pints
x = 0.375 pints
Step 2
Convert pints to Quart
1 pints = 0.5 quart
0.375 pint = x quart
Cross Multiply
x quart = 0.375 × 0.5 quart
x quart = 0.1875 quart
Step 3
Convert from quart
1 quart = 0.94 liter
0.1875 quart = x liter
Cross Multiply
x liter = 0.1875 × 0.94 liter
x liter = 0.17625 liters
Approximately to 4 significant figures= 0.75 cup = 0.1763 liters
Answer:
0.75 cup = 0.1763 liters
