Answer:
Check the solution in both equations. The solution is ( − 1, 2). Solve the system by graphing: {− x + y = 12 x + y = 10 . Solve the system by graphing: {2x + y = 6 x + y = 1 . In all the systems of linear equations so far, the lines intersected and the solution was one point.

y=3/4x
5/2x+2y=5
What is the value of X?
Answer:x = 5/4
Step-by-step explanation: We are given y = 3/4x
and 5/2x +2y = 5
Substituting the value y=3/4 x in second equation we get
5/2x + 2(3/4)x = 5
8/2x = 5
4x = 5
and so , x = 5/4
substituting value of x in y = 3/4x we get,
y = 3/4 (5/4)
So, y = 15/16
which are the required values of x and y on solving the two given equations.

If the point T(3,-4) is translated 2 units left and 3 units up, the coordinates of T' will be .
Answer:
T' (1, -1)
Step-by-step explanation:
Since it is 2 units left, we subtract 2 from the x value and since it is 3 units up, we add 3 to the y value.
Mila owns a small business selling used books. She knows that in the last week 83 customers paid cash, 16 customers used a debit card, and 41 customers used a credit card. Based on these results, express the probability that the next customer will pay with something other than a credit card as a decimal to the nearest hundredth
Answer:
the answer is 0.71
Step-by-step explanation:
it told me
The probability the next customer will pay with something other than a credit card is 0.71.
What is probability?Probability deals with the occurrence of a random event. The chance that a given event will occur. It is the measure of the likelihood of an event to occur.The value is expressed from zero to one.
For the given situation,
Number of customers paid cash = 83
Number of customers used a debit card = 16
Number of customers used a credit card = 41
Total number of customers = 140
The probability that the next customer will pay with something other than a credit card is
P(e) = (Number of customers paid cash + Number of customers used a debit card) / Total number of customers.
⇒ [tex]P(e)=\frac{83+16}{140}[/tex]
⇒ [tex]P(e)=\frac{99}{140}[/tex]
⇒ [tex]P(e)=0.7071[/tex] ≈ [tex]0.71[/tex]
Hence we can conclude that the probability the next customer will pay with something other than a credit card is 0.71.

Terrel lives 2 5/6 blocks away from his best friends house. His school is 4 1/3 blocks away in the same direction. If he stops at his best friends house first how much farther do they have to walk to school.
Answer:
5/8 of a mile
Step-by-step explanation:
Let the distance from Post Office to Friend's house =D
7/8 + 5/6 + D =miles - Total distance from Georgia's house to a Friend's house.
42 minutes / 18 minutes per mile =2 1/3 miles - total distance from her house to a friend's house. So, we have:
7/8 + 5/6 + D = 2 1/3, solve for D
[21 + 20] / 24 + D = 2 1/3
41/24 + D = 2 1/3 subtract 41/24 from both sides
D =2 1/3 - 41/24
D =7/3 - 41/24
D =[56 -41] / 24
D = 15 / 24
D = 5/8 of a mile - the distance between the School and her Friend's house.

The question is a model of rectangular stove top with four circular burners is shown the side length of the top stove and the diameter of the burners are labeled.which measurement is the best estimate of the area and square inches of the stove top that does not include the area of the burners?
Answer: see work
Step-by-step explanation:
Total area is 24x22=528
one circle area is (pi)3^2=9(pi)
that times 4 because of 4 circles =36(pi)
so the total are minus the circles now
in terms of pi the answer is 528-36(pi)
if pi = 3.14 the answer in 414.96
- ZA and B are complementary angles. If mA = (x + 28)° and m ZB = (4x - 8), then find the measure of ZA.
Answer:
42 degrees
Step-by-step explanation:
"Complementary" means the angle measures add up to 90 degrees.
[tex]m\angle A+m\angle B =90^\circ\\(x+28)+(4x-8)=90\\5x+20=90\\5x=70\\x=14[/tex]
Now plug in 14 for x in the expression for the measure of angle A.
[tex]m\angle A = 14^\circ+28^\circ =42^\circ[/tex]

What equation represents the graph shown? Using the equation
editor, enter an equation that represents the graph.
Given:
The graph of a line.
To find:
The equation for the given line.
Solution:
If a line passes through two points, then the equation of the line is:
[tex]y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)[/tex]
From the given graph it is clear that the line passes through the points (-1.5,0) and (0,1). So, the equation of the line is:
[tex]y-0=\dfrac{1-0}{0-(-1.5)}(x-(-1.5))[/tex]
[tex]y=\dfrac{1}{1.5}(x+1.5)[/tex]
[tex]y=\dfrac{1}{1.5}(x)+\dfrac{1}{1.5}(1.5)[/tex]
[tex]y=\dfrac{1}{1.5}x+1[/tex]
Therefore, the equation of the given line is [tex]y=\dfrac{1}{1.5}x+1[/tex].
In 2018 sienna invested 5000. The value of the invest,ent increases by 3%each year compounded weekly if she doesn't make additional transactions, what will be the value of her investment in 2025
Answer:
6168.02
Step-by-step explanation:
The formula for calculating future value:
FV = P (1 + r/m)^mn
FV = Future value
P = Present value - 5000
R = interest rate = 0.03
N = number of years = 7
m = Number of compounding = 52
5000 x ( 1.000577)^52 x 7 = 6168.02
The polynomial
y = (x - 5)(x - 2)(4x + 3)
has been graphed incorrectly. Identify the
error and how to fix the graph.
Answer:
y = (x+5)(x+2)(4x-3)
Step-by-step explanation:
This is almost correct but the problem is that the signs should be flipped...
Why? If we solve for x-5=0 the answer we would get is 5, but the graph shows -5 as its zero so that doesn't match
The revised version would be the opposite signs
y = (x+5)(x+2)(4x-3)

Which equation has a axis of symmetry of x=4 ?
I think you forgot to add the picture. However, any x = 4 equation will result in a graph with a vertical line on the x-axis. For example x = 20 will be a vertical line on x-axis 20.
Or, in a more difficult equation like this...
10x - 60 = 10
10x = 10 +60
10x = 70
x = 7,
where the graph looks like a vertical line with a point on the x axis on 7.
