Step-by-step explanation:
y=1/3x+5 through (2,1)
Answer:
No solution
Step-by-step explanation:
1 = 1/3(2) + 5
1 = 17/3
1 is not equal to 17/3
so the answer has no solution meaning the point does not exist in the graph.
4. A car is priced at $7200. The car dealer allows a customer to
pay a one-third deposit and 12 payments of $420 per month.
How much extra does it cost the customer?
Answer:
$240 extra
Step-by-step explanation:
1/3(7200) + 12(420) = 2400 + 5040 = 7440
7440 - 7200 = 240
The customer had to pay 1720 extra.
What is Unitary Method?The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.
For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.
12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.
As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.
This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.
Given:
A car is priced at $7200.
If the deposit is one third = 7200/3
= 240
The amount after 12 payments will be
= 240 x 12
= 2880
total cost will be
= 2880 + 2400
= 5280
and, The customer had to pay extra amount
= 7200 - 5280
= 1720

Find the length of RA. A. 42 B. 84 C. 14 D. 7
Answer:
[tex]\large \boxed{\mathrm{B. \ 84}}[/tex]
Step-by-step explanation:
[tex]LU[/tex] bisects [tex]RU[/tex] and [tex]UA[/tex].
[tex]RU=UA[/tex]
[tex]3m+21=6m[/tex]
Solve for m.
Subtract 3m from both sides.
[tex]21=3m[/tex]
Divide both sides by 3.
[tex]7=m[/tex]
Calculate [tex]RA[/tex].
[tex]RA=3m+21+6m[/tex]
[tex]RA=9m+21[/tex]
Put m = 7.
[tex]RA=9(7)+21[/tex]
[tex]RA=63+21[/tex]
[tex]RA=84[/tex]
Answer:
B) 84
Step-by-step explanation:
ΔLRU ≅ ΔLAU {SAS congruent}
Therefore, UA = UR {CPCT}
6m = 3m +21
Subtract 3m from both sides
6m - 3m = 3m + 21 -3m
3m = 21
Divide both sides by 3
3m/3 = 21/3
m = 7
RA = RU + UA
= 3m + 21 + 6m {add like terms}
= 9m + 21 {Plug in m =7}
= 9*7 + 21
= 63 + 21
RA = 84 units

38
X = 10
Answer:
x = 10
Step-by-step explanation:

Add 6 on both sides of the equation.
5x = 50
Divide by 5 on both sides of the equation.
x = 10
So, the value of x is equal to 10
Answer:
x=10
Step-by-step explanation:
5x-6=44
grouping constants and numbers with coefficient of x we get
5x=44+6
5x=50

x=10
What expression has the same value as -3/2-(2-3/8)+3/2
Answer:
[tex]\dfrac{-3}{2}-(2-\dfrac{3}{8})+\dfrac{3}{2}=\dfrac{-13}{8}[/tex]
Step-by-step explanation:
We need to find the value of expression [tex]\dfrac{-3}{2}-(2-\dfrac{3}{8})+\dfrac{3}{2}[/tex].
Firstly solving the second term as :
[tex](2-\dfrac{3}{8})=\dfrac{16-3}{8}=\dfrac{13}{8}[/tex]
Now the above expression becomes,
[tex]\dfrac{-3}{2}-(2-\dfrac{3}{8})+\dfrac{3}{2}\\=\dfrac{-3}{2}-\dfrac{13}{8}+\dfrac{3}{2}[/tex]
-3/2 and +3/2 equals 0.
It means that, [tex]\dfrac{-3}{2}-(2-\dfrac{3}{8})+\dfrac{3}{2}=\dfrac{-13}{8}[/tex]
A survey of 100 people found that 35 people exercise in
the morning, 45 people exercise in the afternoon, and 20
people exercise at night. Tara claims that 35:55, 45:80,
and 20:65 are possible ratios from this data. Jim claims
that 35:100, 45:100, and 20:100 are possible ratios from
this data. Who is correct? Explain.
Answer:
Jim's claim is correct
Step-by-step explanation:
Total survey=100 people
Morning exercise=35 people
Afternoon exercise=45 people
Night exercise=20 people
Morning exercise : Total survey
=35 : 100
Afternoon exercise : Total survey
=45 : 100
Night exercise : Total survey
=20 : 100
Jim's claim is correct because in finding the ratio, one has to relate it with the total people involved in the survey.
Tara's claim however seems to relate one variable with two other variables
Example:
35 : 55
Morning exercise : (morning exercise + night exercise)
35 : (35+20)
35 : 55
Answer:
Sample Response: Jim is correct because 35:100, 45:100, and 20:100 are part-to-whole comparisons. There are other possible part-to-part ratios from the data.

The amount of clay students used for their last art project is weighed. The line plot displays the amounts of clay. How much more clay did the students who used of a pound use than the students who used of a pound?
Answer:
C. 2 [tex]\frac{1}{4}[/tex]
Step-by-step explanation:
First, calculate the amount of clay that both groups used in total. We can find this by multiplying the amount by the number of students.
Used 3/4 of a pound:
3/4(4) = 3 pounds
Used 1/4 of a pound:
1/4(3) = 3/4 pound
Now, subtract:

What will be the effect on the graph of y = |x| if x is replaced with -x?
A. a vertical shift
B. no change
C. a reflection over the x-axis
D. a horizontal shift of 1 unit to the left
The vertical lines on each side of the x mean it is the absolute value of x.
Replacing x with -x would make no change on the graph, because the absolute value is always a positive number.
The answer is B.
There will be no change on the graph of y = |x| if x is replaced with -x. Option B is correct.
A function is defined as the expression that set up the relationship between the dependent variable and independent variable.
The vertical lines on each side of the x mean it is the absolute value of x. Replacing x with -x would make no change on the graph because the absolute value is always a positive number.
Therefore, there will be no change on the graph of y = |x| if x is replaced with -x. Option B is correct.

The graph of y vx is translated 5 units to the left and 7
units up. What is the equation of the graph that results from
this translation?
y=-1.4x
Step-by-step explanation:
divide the change in y by the change in x to find the gradient,
7 divided by -5 [as the translation is to the left].
there might be a y intercept value, c as in
y=mx + c but with the given information without thee starting points it is hard to find
The required equation of the graph that results from the translation is y = √(x + 5) + 7.
What is translation on the coordinate plane?Translation on a coordinate plane is a transformation that moves an object or figure from its original position to a new position in a straight line. It is also called a "slide." In translation, all points of the object are moved by the same distance in the same direction.
Here,
To shift the graph of the function y = √x to the left by 5 units, we need to replace x with x + 5 in the equation. This will give us the graph of y = √(x + 5).
To shift the graph 7 units up, we need to add 7 to the entire function. This will give us the final equation of the translated graph:
y = √(x + 5) + 7.
Therefore, the equation of the graph that results from the translation is y = √(x + 5) + 7.

2. A business man sold an article at a gain of 10%. Had he sold the article at a gain of 20% he would have gained Rs. 55 more. Find the cost price of the article.
Step-by-step explanation:
Let SP1 be x
P%=10%
CP=SP×100/100+%P
= x+100/100+10
= 100x/110
SP2= x+55
CP= SP×100/100+%P
or 100x/110= x+55×100/120
or x/110=x+55/120
or 24x-22x=22×55
or 2x=1210
or x=1210/2
or x=605
