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.

The zeros of a quadratic function
are 5 and -9. What would be a
possible function for those
solutions?
Answer:
(x-5)(x+9) = 0
Step-by-step explanation:
In the equation above, if you plugged in the values given(5, and -9) then you will see that the answer i s0. You basically takes the zeroes you are given, and invert their signs to form the equation.
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.
- 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]
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.

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 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)

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].
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.

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

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)

Answer:
130
Step-by-step explanation:
x + 95 + 35 = 180
x + 130 = 180
x = 50
x + y = 180
50 + y = 180
y = 130
Answer:
130°
Step-by-step explanation:
the sum of the angles in a triangle are 180°
we need to subtract the sum of the other two angles in order to find angle ∠QPG
180-(35+95)=180-130=50°
the question is asking for the external angle of angle ∠QPG (the value that we find when we subtract the angle from 180°)
so we are going to subtract 50 from 180
180-50=130°
2nd way:
the sum of the two inner angles are equal to the external angle of the third angle:
35+95=130°--> ∠QPG
