Answer:
X = 11/20
Step-by-step explanation:
7/4x-3=2+9/2x
We move all terms to the left:
7/4x-3-(2+9/2x)=0
Domain of the equation: 4x!=0
x!=0/4
x!=0
x∈R
Domain of the equation: 2x)!=0
x!=0/1
x!=0
x∈R
We add all the numbers together, and all the variables
7/4x-(9/2x+2)-3=0
We get rid of parentheses
7/4x-9/2x-2-3=0
We calculate fractions
14x/8x^2+(-36x)/8x^2-2-3=0
We add all the numbers together, and all the variables
14x/8x^2+(-36x)/8x^2-5=0
We multiply all the terms by the denominator
14x+(-36x)-5*8x^2=0
Wy multiply elements
-40x^2+14x+(-36x)=0
We get rid of parentheses
-40x^2+14x-36x=0
We add all the numbers together, and all the variables
-40x^2-22x=0
a = -40; b = -22; c = 0;
Δ = b2-4ac
Δ = -222-4·(-40)·0
Δ = 484
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
x1=−b−Δ√2ax2=−b+Δ√2a
Δ−−√=484−−−√=22
x1=−b−Δ√2a=−(−22)−222∗−40=0−80=0
x2=−b+Δ√2a=−(−22)+222∗−40=44−80=−11/20
Triangle ABC pictured above has a right angle at C. If a=4.3 and c=9, find the measure of angle B. Round to the nearest tenth of a degree.

Answer:
1
Step-by-step explanation:
give me brainliest
The number is -12 in the inequality x + 4y ≥ ?
What is an inequality?In mathematics, an inequality is a relation which makes a non-equal comparison between two numbers or other mathematical expressions.
Given is a system of linear inequalities represented by the graph [attached]
We need to find the missing number,
y ≥ 2x – 2 and x + 4y ≥ ?
The linear equation with slope m and intercept c is given as follows.
y = mx + c.
The formula for slope of line with points (x₁, y₁) and (x₂, y₂) can be expressed as,
m = y₂ - y₁ / x₂ - x₁
The orange line intersects y-axis at (0, -2), therefore the y-intercept is -2.
The orange line intersects the points that are (1, 0) and (0, -2).
The slope of the line can be obtained as follows,
m = 2,
The slope of the line is m = 2.
Therefore, the orange line is y ≥ 2x – 2.
The blue line intersects y-axis at (0, -3), therefore the y-intercept is -3.
The blue line intersect the points that are (-4, -2) and (0, -3).
The slope of the line can be obtained as follows.
m = -1/4
The inequalities is x + 4y ≥ b passes through the point (0, -3).
0 + 4(-2) ≥ b
-12 ≥ b
Hence the number is -12 in the inequality x + 4y ≥ ?

Raymond used 36 cubes to build the first layer of a rectangular prism. The edge length of each cube was 1 inch. The finished prism had a total of 8 layers. What is the volume of Raymond’s prism in cubic inches?
Answer:
[tex]Volume=288in^{3}[/tex]
Step-by-step explanation:
Given
Base Cubes =36
Layers = 8
The number of base cubes represents the base area and the number of layers represents the height of the prism.
So, the volume is calculated as:
Volume = Base Cubes * Layers, i.e Base Area * Heights
Volume = [tex]36*8[/tex]
Volume = [tex]36in^{2} * 8 in[/tex]
Volume = [tex]288in^{2}[/tex]
• There are 20 pounds of the mixture.
• Peanuts cost $2.95 per pound.
• Almonds cost $5.95 per pound.
• The mixture costs $4.00 per pound.
How many pounds of peanuts will there be?
Answer:
6.63 pounds
Step-by-step explanation:
Total pounds of mixture = 20
The contents of the mixture are; peanuts and almonds. Of which;
Peanuts cost = $2.95 per pound
Almonds cost = $5.95 per pound
The mixture cost = $4.00 per pound
Total cost of contents of the mixture = $8.90
The pounds of peanuts = [tex]\frac{2.95}{8.90}[/tex] x 20
= 6.63
Therefore, 6.63 pounds of peanuts was used in producing 20 pounds of the mixture.

80
7436 and k+ 80
+80 and k+36
and
36
Answer:
(C) j/j+80 and 36/k+36
Step-by-step explanation:
From the table attached :
Total Email (positive + negative) = j + 80
Number of positive Emails = j
Fraction of positive emails = (number of positive / total number of emails) = j / (j + 80)
Total phone calls (positive + negative) = 36 + k
Number of positive Emails = 36
Fraction of positive emails = (number of positive / total number of emails) = 36 / (k + 36)
What is the slope of (-6, 1) and (2,5)?
Answer:
1/2
Step-by-step explanation:
To find the slope given two points, use the slope formula
m= ( y2-y1)/(x2-x1)
= ( 5-1)/(2--6)
= (5-1)/(2+6)
= 4/8
= 1/2
Answer:
slope = [tex]\frac{1}{2}[/tex]
Step-by-step explanation:
Calculate the slope m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (- 6, 1) and (x₂, y₂ ) = (2, 5)
m = [tex]\frac{5-1}{2+6}[/tex] = [tex]\frac{4}{8}[/tex] = [tex]\frac{1}{2}[/tex]
