What is the solution of the equation 2X = 7? Round your answer to the nearest ten-thousand.
Answer:
x =2.8074
Step-by-step explanation:
2^x = 7
Take the log of each side
log (2^x) = log (7)
We know log a^b = b log a
x log 2 = log 7
x = log (7) / log 2
x =2.80735
To the nearest tenth thousandth
x =2.8074

y-intercept of –7 and a slope of 3/2
Answer:
y=3/2x-7
Step-by-step explanation:
Slope-intercept formula: y=mx+b
m= slope
b= y-intercept
Replace the "m" and "b" the number that is given it
So the slope of 3/2 will look like this in the equation:
y=3/2x+b
THe y-intercept of -7 will look like this in the equation with the slope:
y=3/2x-7

What are the x and y intercepts of the graphed functionality ?
Answer:
Step-by-step explanation:
the x intercepts are -1 and 1 (where y = 0)
the y intercept is 1 (where x = 0)
Answer:
X-intercepts: (1,0) and (-1, 0)
Y-intercept: (0,1)
Step-by-step explanation:
I believe the x-intercepts also have a multiplicity of 2 each if you need to know that.

Which expression is equal to (−4x2−1)(2x2+3)?
−8x4−14x2−3
−8x4−10x2+3
−8x2−14x−3
8x4−14x2+3
Answer:
The first one:
−8x4−14x2−3
Step-by-step explanation:
(-4•2-1)(2•2+3)
-4•2 = -8
-8 - 1 = -9
(-9)(2•2+3)
2•2 = 4
4+3 = 7
(-9)(7) = -63
Now we find the one that equals -63:
-8•4-14•2-3
(-8•4)-14•2-3
-32-14•2-3
-32-(14•2)-3
-32-28-3
(-32-28)-3
-60-3
-60-3 = -63

Simplify expression using order of operations
uhhhh
Step-by-step explanation:
Answer:
72
Step-by-step explanation:
To solve 46 + {[3(2+5)]+5}, you would first do what is inside the () so that would be 2+5, then you would move outward multiplying 7 by 3 to get 21, then adding 5 to get 26. Then you would finally add 46 to get 72

Jesse makes a 6% commission on every spa where makes if he sold $875 worth of items this week, how much will he make in commission
Answer:
$52.50
Step-by-step explanation:
6% of 875
0.06*875
52.5
Jesse will make $52.50 in commission this week if he sold $875 worth of items.
What is the percentage?The percentage is the ratio of the composition of value to the whole composition of value multiplied by 100.
Here,
To calculate Jesse's commission, we can multiply the total sales by the commission rate:
Commission = Total Sales × Commission Rate
In this case, the total sales are $875 and the commission rate is 6%, so:
Commission = $875 × 6% = $52.50
Therefore, Jesse will make $52.50 in commission this week if he sold $875 worth of items.

The graph below shows the number of plates arranged on different numbers of tables in a room: A graph is shown. The values on the x-axis are 0, 1, 2, 3, 4, 5. The values on the y-axis are 0, 6, 12, 18, 24, and 30. Points are shown on ordered pairs 0, 0 and 1, 6 and 2, 12 and 3, 18 and 4, 24. These points are connected by a line. The label on the x-axis is Number of Tables. The title on the y-axis is Number of Plates. What does the point (1, 6) on the graph represent? (1 point) The ratio of plates to tables in the room is 7:1. The ratio of tables to plates in the room is 7:1. There are 6 plates for every 1 table in the room. There are 6 tables for every 1 plate in the room.

The titanium content of an alloy is being studied in the hope of ultimately increasing the tensile strength. An analysis of six recent heats chosen at random produces the following titanium contents. 9.7% 7.4% 5.9% 7.7% 7.5% 8.9% What is the value of the test statistic, if the alternative hypothesis is the mean titanium content is greater than 9.5%?
Answer:
Tstatistic = - 3.068
Step-by-step explanation:
Given the data: 9.7% 7.4% 5.9% 7.7% 7.5% 8.9%
Mean titanium > 9.5%
Test statistic :
(m - μ) / (s/√n)
From the data: obtain the sample mean and standard deviation
From the data given ;
Calculate the same mean and standard deviation :
Using calculator :
Sample mean (m) = ΣX / n
Sample size (n) = 6
m = 47.1 / 6 = 7.85
Standard deviation (s) :
Using calculator = 1.317
Hence,
(m - μ) / (s/√n)
Tstatistic = (7.85 - 9.5) / (1.317/√6)
Tstatistic = - 1.65 / 0.5376629
Tstatistic = - 3.068
5a - 25d factor using the GCF
Answer: 5(a-5d)
Step-by-step explanation:
The GCF (the largest number that can be factored evenly out of the expression is 5. Thus, we divide out 5 from the expression, leaving a and -5d inside of the paranthesis.
We can check our work by redistributing 5 to the factor within the parenthesis. This will prove whether or not your factoring is correct. In this case, taking out the 5 is the correct factorization.
