Answer:
see below
Step-by-step explanation:
-15 = 2x + 1
Subtract 1 from each side
-15-1 = 2x + 1-1
-16 = 2x
Divide each side by 2
-16/2 = 2x/2
-8 =x
Check
-15 = 2(-8) + 1
-15 = -16+1
-15 = -15
Answer:
-8
Step-by-step explanation:
subtract 2x to move it to the left side
-2x-15=1
add 15 to move it to the right side then add 1 to 15 since it would be 15 plus 1
-2x=16
divide by -2 to get x by its self
-2x=16/2x
If m 4= 138, then what is m 5 ?
42
48
138
142?
Answer:
42
Step-by-step explanation:
im pretty sure I got this right I did it in my head
Answer:
m 5 = 42
Step-by-step explanation:
A line is 180 degrees. m 4 = 138 degrees. 180 - 138 = 42 degrees. this makes m 1 = 42 degrees and m 5 is equal to m 1.

Which best describes the type of association shown in this scatter plot?
•no association
•non-linear association
•positive linear association
•negative linear association
Answer:
Negative linear association/correlation.
Step-by-step explanation:
The type of association that is shown in the scatter plot is negative linear association since it declining at a steady rate with a few outliers. It resembles a line going downwards or sloping downwards.
The best describes the type of association shown in this scatter plot is,
⇒ negative linear association
We have to given that,
A scatter plot is shown in figure.
Since, this scatter plot declining at a steady rate with a few outliers.
And, It resembles a line going downwards or sloping downwards.
Hence, The type of association that is shown in the scatter plot is negative linear association.
Thus, The best describes the type of association shown in this scatter plot is,
⇒ negative linear association

The perimeter of a rectangle is 34 units its width is 6.5 Units
Write an equation to determine the length(l) of the rectangle.
Answer: Length=10.5
Step-by-step explanation: P=34 and W=6.5. This can also be known as Perimeter=W+L+W+L=2(W+L). In this case, it would be 34= 2(6.5 +L). 34=13+2L.(The 2L's are crossed out now because they cancel both out)
-2L -2L (There is a line going down at the equal sign.
34+-2L=13 Subtract 34 from both sides and cancel the two 34's out)
-34 -34
-2L=-21 (Divide both sides by -2) (Cancel out the -2's)
/-2 /-2
L = 10.5
List the metric system units for measuring length in order from greatest to least. Centimeter. Kilometer. Meter. Millimeter.
Answer:
millimeter
centimeter
meter
kilometer
Step-by-step explanation:
Measure of Lengths
10 millimeters (mm) = 1 centimeter (cm)
10 centimeters = 1 decimeter (dm) = 100 millimeters
100 centimeter = 1 meter (m) = 1,000 millimeters
1000 meters = 1 kilometer (km)
find the missing angle. 9 5 x°
Answer:
45 degrees
Step-by-step explanation:
the right angle is 90 degrees and one angle is 45 degrees and 90+45=135 and 180-135=45 so 45 degrees is the missing angle
What substitution should be used to rewrite 4x12 – 5x6 – 14 = 0 as a quadratic equation?
Answer:

Let m = x^6
4m^2 - 5m - 14 = 0
How are the measures of the interior angles of a triangle related to the measures of the exterior angles of the triangle ?
Answer:
one interior angle + one exterior angle = 180 degrees
Step-by-step explanation:
This is because the two angle form a straight line, which equal to 180 degrees.

Answer:
As the angles are supplementary, their sum is 180
123 + 3x = 180
3x = 57
x = 19
Answer:
x° = 19°
Step-by-step explanation:
[tex] = > 123 \degree + 3x \degree = 180 \degree \\ \\ = > 3x\degree = 180\degree - 123\degree \\ \\ = > 3x\degree = 57\degree \\ \\ = > x\degree = (\frac{57}{3} )\degree \\ \\ = > x\degree = 19\degree [/tex]

Step-by-step explanation: Rise/Run, pick two points and use the formula (y2-y1)/(x2-x1)
Answer:
1
Step-by-step explanation:
the function is
f(x) = x - 2.
This is in m(x) + b form, so whatever is before the x is the slope. Since X is just by itself, the slope is 1.

A quadrilateral has 2 pairs of congruent angles and 4 congruent sides. What is the name of the quadrilateral?
Answer: Rhombus
A rhombus is a quadrilateral with all four sides the same length. If all four angles are the same (all 90 degrees), then the rhombus is more specifically a square. Any rhombus is a parallelogram which is why we have congruent opposite pairs of angles.
Beccas dad told her that she needs to practice piano for two hours this week so far she has practiced 20 minutes on Monday a half an hour on Tuesday and 15 minutes on Wednesday how much longer does she need to practice?
Answer:
Step-by-step explanation:
She needs to practice piano for 2 hours this week:
Lets add the time she played the piano so far:
Monday + Tuesday + Wednesday
Which is
20 + 30 (half an hour) + 15
= 65 minutes
In which 2 hours is equal to 120 minutes
So,
120 - 65 = 55
She needs to practice for 55 more minutes in this week

The given bar graph shows the percentage of U.S. women in the labor force from 1960 through 2010. The function f left parenthesis x right parenthesis equals 3.5 square root of x plus 38 models the percentage of U.S. women in the labor force, f left parenthesis x right parenthesis , x years after 1960. Use this formula to solve the following questions.
US women in Labor ForceAccording to the model above, approximately what percentage of women will be a part of the work force in 1996? Does the given bar graph verify this result? Explain why or why not. Use complete sentences and proper labels to answer.
Answer:
59% of women will be a part of the work force in 1996
According to the bars, the percentage was in the range of 57.5 - 60.2. This verify the previous result.
Step-by-step explanation:
In the figure attached, the bar graph is shown.
f(x) = 3.5√x + 38
where f(x) models the percentage of U.S. women in the labor force x years after 1960. In 1996, x = 1996 - 1960 = 36. Replacing it into the equation:
f(36) = 3.5√36 + 38 = 59%
A clothes shop has some special offers.
T-shirts are buy one get one free and jumpers are 3 for 2.
The normal price of a T-shirt is £3.50 and the normal price of a jumper is £16.
How much does it cost to get 3 jumpers and 8 T-shirts using this offer as appropriate?
Answer:
£142 for 3 jumpers and 8 T-shirts
Step-by-step explanation:
Since the T-shirts cost £3.50 each and they are buy one get one free, when you buy 8 T-shirts you only pay for 4 of them.
£3.50(4) = £140 for the 8 T-shirts
Since you bought 3 jumpers with a buy 3 for £2 sale, the 3 jumpers cost £2.
Add the amount of money all together to find the total cost of the T-shirts and jumpers.
£140 + £2 = £142

What is an
equation of the line that passes through the points (-3,8) and (4,1)?
Answer: y= -1x + 5
Step-by-step explanation:
(-3,8) ( 4,1)
8-1= 7
-3-4 = -7
7/-7 = -1 so the slope is -1 so we will use the formula y=mx+b to find the y-intercept
8= -1(-3) + b
8= 3 + b
-3 -3
b= 5 so the y intercept is 5 now we will write the equation like this y= -1x + 5

Which statement(s) can be interpreted from the equation for a real estate value, V(C)=228,000(1.03)' where V(C) represents the value of the real estate and t represents the time in years?
The equation is an exponential growth equation.
The equation is an exponential decay equation
The equation is neither exponential decay nor exponential growth
$228,000 represents the initial cost of a real estate that appreciates 3% per year over the course of years.
$228,000 represents the initial cost of a real estate that appreciates 30% per year over the course of t years
$228,000 represents the initial cost of a real estate that depreciates 3% per year over the course of t years
$228,000 represents the initial cost of a real estate that depreciates 30% per year over the course of t years
Answer:
The equation is an exponential growth equation.
$228,000 represents the initial cost of a real estate that appreciates 3% per year over the course of years.
Step-by-step explanation:
the correct equation is: V(C)=228,000(1.03)^t
Hi, to answer this question we have to apply an exponential growth equation:
A = P (1 + r) t
Where:
p = initial cost
r = growing rate (decimal form)
t= years
A =cost after t years
Before applying the formula:
1.03 = 1+r
1.03-1 =r
0.03=r
Replacing with the values given:
A = 228,000 (1+ 0.03)^t
r = 0.03
Since r is in decimal form, we have to multiply it by 100
0.03 x 100 = 3% appreciation per year
Feel free to ask for more if needed or if you did not understand something.

no solution
Answer:
no solution
Step-by-step explanation:
when you substitute [tex]y[/tex] for [tex]-2x+4[/tex] the equation is false
how I solved this:
1. substitute [tex]y[/tex] for [tex]-2x+4[/tex]
[tex]6x+3(-2x+4)=-12[/tex]
2. distribute the 3
[tex]6x+-6x+12=-12[/tex]
3. combine like terms
[tex]12=-12[/tex]
this is incorrect because 12 does not equal -12, so there is no solution
