Answer:
C
Step-by-step explanation:
Answer:
D.) y=5x+14
Step-by-step explanation:
point slope form: y-y1=m(x-x1)
y1=4, m=5, x1=-2
y-4=5(x+2)
distribute 5
y-4=5x+10
add 4 to both sides
y=5x+14
9. Consider f(x) = x³+x¹. Would the function be even, odd, neither, or not enough information to determine? A. even B. Odd C. Neither D. Not Enough Information
The function is odd, since
f(-x) = (-x)³ + (-x)
… = (-1)³ x³ - x
… = -x³ - x
… = -(x³ + x)
… = - f(x)
so the answer is B.
What is the value of x in the equation 5(3x + 4) = 23?
start fraction 43 over 15 end fraction
start fraction three over 15 end fraction
start fraction 15 over 43 end fraction
start fraction two over five end fraction
Answer:
5(3x+4)=23
5*3=15 5*4=20
15x+20=23
-20=-20
15x=3
divide by 15 from both sides
x=0.2
Step-by-step explanation:
Answer:
5(3x+4)=23
5*3=15 5*4=20
15x+20=23
-20=-20
15x=3
divide by 15 from both sides
x=0.2
Explanation: In a fraction, the number of equal parts being described is the numerator (from Latin: numerātor, "counter" or "numberer"), and the type or variety of the parts is the denominator (from Latin: dēnōminātor, "thing that names or designates"). As an example, the fraction 8/5
amounts to eight parts, each of which is of the type named "fifth". In terms of division, the numerator corresponds to the dividend, and the denominator corresponds to the divisor.
Informally, the numerator and denominator may be distinguished by placement alone, but in formal contexts they are usually separated by a fraction bar. The fraction bar may be horizontal (as in 1/3), oblique (as in 2/5), or diagonal (as in 4⁄9). These marks are respectively known as the horizontal bar; the virgule, slash (US), or stroke (UK); and the fraction bar, solidus, or fraction slash. In typography, fractions stacked vertically are also known as "en" or "nut fractions", and diagonal ones as "em" or "mutton fractions", based on whether a fraction with a single-digit numerator and denominator occupies the proportion of a narrow en square, or a wider em square. In traditional typefounding, a piece of type bearing a complete fraction (e.g. 1/2) was known as a "case fraction", while those representing only part of fraction were called "piece fractions".

what’s the slope of the line that passes through the points (-5,6) and (11,2)??
Answer:
-0.25Step-by-step explanation:11 - (-5) is 16 and 2 - 6 is -4 and -4 divided by 16 is -0.25
Answer:
-0.25Step-by-step explanation:
This is because when calculating the slope of given points, we must use this simple formula:
Slope= rise/run = Δy/Δx(simplified version)
The actual formula is
slope = (y₂ - y₁) / (x₂ - x₁)PROCESS:1. Find the difference of the x axis'
ANSWER: The difference of the x axis should be 11-(-5)= 16
2. Find the difference of the y axis'
ANSWER: The difference of the y axis should be 2-(6)= -4
3. Substitute these new values into the formula Δy/Δx
ANSWER: You should get -4/16 which is -0.25
4. Your answer will be -0.25

A manufacturer wants to construct a box whose base length is 4 times the base width. The material to build the top and bottom cost 8 dollars per ft.2 and sides 5 dollars per ft.2. If the box must have a volume of 72 ft.3, determine the dimensions that will minimize cost.
Answer:
width = 1.77845 ft
length = 7.1138 ft
height = 5.691 ft
total cost = $759.09
Step-by-step explanation:
volume = length x width x height
length = 4 width
base of the rectangle = 4 x 1 w = 4w²
72 (volume) = 4w²h
18 = w²h
f(c) = (2 x 4w² x $10) + (2 x wh x $5) + (2 x 4wh x $5)
f(c) = 80w² + 10wh + 40wh
f(c) = 80w² + 50wh
since we need only 1 variable (width), we have to substitute h:
h = 18/w²
f(c) = 80w² + 50w(18/w²) = 80w² + 900/w
f'(c) = 160w + 900/w²
0 = (160w³ + 900)/w²
0 = 160w³ + 900
0 = 20(8w³ + 45)
0 = 8w³ + 45
8w³ = -45
w³ = -45/8
w = ∛-45/8 = -1.77845 and 1.77845
since w cannot be negative, then it must be 1.77845

Question on pictures ^^^^^^^^
Answer:
y=35 x=145
Step-by-step explanation:
y is equivalent to 35
180-35=145
Answer:
x = 145
y = 35
Step-by-step explanation:
x and the 35 degree angle are supplementary angles, so x + 35 = 180.
solve for x, x = 145. the 35-degree angle and angle Y are corresponding angles, so the value of y will be 35.

18) If Holstein cows produce milk that is on average 3.66% butterfat and Jersey
cows produce milk that is on average 4.5% butterfat, how many gallons of Jersy milk
should be added to every 100 gal of Holstein milk to have milk that is 4% butterfat?
Guys please help me with this question I’m using all my points for this please just help me
Answer:
68 gallonsStep-by-step explanation:
Milk of Holstein cows ⇒ 3.66% butterfatMilk of Jersey cows ⇒ 4.5% butterfatIf we add x gal of 4.5% milk, then we have below equation:
100*0.0366 + x*0.045 = (100 + x)*0.043.66 + 0.045x = 0.04x + 40.045x - 0.04x = 4 - 3.660.005x = 0.34x = 0.34/0.005x = 68 galA rectangle is 12 feet long and 5 feet wide.

Sally went to the clearance rack at a department store and found a shirt she wanted to buy. The shirt was $36.00 and is on sale for $24.00. What is the percent of the decrease?
Answer:
33.34%.
Step-by-step explanation:
Given that,
The actual price of the shirt = $36
Price on sale = $24
We need to find the percent of the decrease. The formula for the percentage is given by :
[tex]\%=\dfrac{|\text{actual value-estimated value}|}{\text{actual value}}\times 100[/tex]
Putting all the values,
[tex]\%=\dfrac{24-36}{36}\times 100\\\\=33.34\%[/tex]
So, the percentage decrease in the price of the shirt is 33.34%.
The length of a rectangle is 4 yd less than three times the width, and the area of the rectangle is 55 ya? Find the dimensions of the rectangle. Length: Width :
Answer:
length = 11 yard
width = 5 yard
Step-by-step explanation:
Area of a rectangle = L W
where A = 55 yard
L = 3W - 4
find: Length
width
solution:
A = L W
55 = (3W - 4) W
55 = 3W² - 4W
3W² - 4W - 55 = 0
use quadratic equation to solve for W:
W = - (-4) ± √(-4)² - 4(3)-55
2(3)
W = 5, W = -11/3
substitute W=5 to equation L = 3W - 4 to solve for L
L = 3W - 4
L = 3(5) - 4
L = 15 - 4
L = 11
therefore, the dimensions of a rectangle:
length = 11 yard
width = 5 yard
I’m looking for x can someone help me
Answer:
x = 30°
Step-by-step explanation:
Since m and n are perpendicular, then
y + 70° = 90° ( subtract 70° from both sides )
y = 20°
thus 40 + y = 40° + 20° = 60°
Then
x + 60° = 90° ( subtract 60° from both sides )
x = 30°
