What is the solution to the given system of equations?
y=4x-28
y=1.5x-18
1(-12,4)
2.(2,-12)
3.(7,0)
4.(7.5,2)
Answer:
Solution (4, -12)None of the listed choices are a solution
Step-by-step explanation:
y = 4x - 28
y = 1.5x - 18
Set the equations equal since both equal y
4x - 28 = 1.5x - 18
Subtract 1.5x from both sides
2.5x - 28 = -18
Add 28 to both sides
2.5x = 10
Divide both sides by 2.5
x = 4
---------------------
use x= 4 in either equation
y = 4x - 28
y = 4(4) - 28
y = 16 - 28
y = -12
--------------------
Solution (4, -12)
Please help, my brain just sucks rn. The area of a rectangle is 93.6 square inches. If the length of one of its sides is 5.2 in. what is its perimeter?
46.4 inch
Step-by-step explanation:
Area=l×b
93.6 =5.2×b
93.6/5.2 =b
So b= 18
Again,
p=2(l+b)
p=2(18+5.2)
p= 2×23.2
p=46.4

Answer:
[tex]144 ft^2[/tex]
Step-by-step explanation:
the area of the sidewalk is the area of the whole plot of land minus the area of the flower bed.
The area of the flower bed: length * width = Area; 10 * 8 = 80
The area of the whole plot:
(3 + 10 + 3) * (3 + 8 + 3) = 16 * 14 = 224
224 - 80 = 144 ft squared

Indicate in standard form the equation of the line through the given points, writing the answer in the equation box
below.
PO.-4). Q15, 1)
Answer:
y = x-4
Step-by-step explanation:
The standard form is;
y = mx + b
where m is the slope and b is the y-intercept
we have the two points as (0,-4) and (5,1)
so we find the slope using the slope formula;
m = (y2-y1)/(x2-x1)
m = (1 + 4)/(5-0) = 5/5 = 1
The y-intercept value is the value of y when x = 0
We already have a point (0,-4) and the equation would be:
y = 1(x) + (-4)
y = x-4

PROBLEM:
Jenni's mother sent her to the Farmers Market to buy 5 pounds(lbs.) of
potatoes. The market sold potatoes by the ounce (oz.) Jenni asked Farmer
Brown for 5 pounds of potatoes. Farmer Brown gave Jenni 64 ounces of
potatoes. Jenni noticed that she did not get 5 lbs. of potatoes. How many
more ounces does she need so that her mother can make 5 lbs. of french
fries?
Answer:
16 ounces
Step-by-step explanation:
1 pound = 16 ounces
16*5 = 80 ounces
5 pounds = 80 ounces
80-64 = 16 ounces

Answer:
C. 17.4
Step-by-step explanation:
add all the numbers and then divide
11 + 14 + 15 + 16 + 16 + 18 + 20 + 20 + 22 + 22 = 174
then divide by the amount of numbers there is which is 10.
174/10 = 17.4

no spam and kindly explain your answer!
Answer:
(x + 1)(x + 2)(2x + 1)(x - 3).
Step-by-step explanation:
From the leading and last coefficients, 2 and -6 the values +/- 1, +/-2 , +/- 3 could be roots of this equation ( well, up to 4 of them).
Try x = 1:
f(1) = 2(1)^4 + 1^3 - 14(1)^2 - 19(1) - 6 = -36 so its not 1.
f(-1) = 2 - 1 - 14 + 19 - 6 = 0 do x = -1 is a root.
Therefore (x + 1) is a factor (By the factor theorem)
Try x = 2:
f(2) = 32 + 8 -56 - 38 - 6 = -6o so x =2 not a root.
f(-2) = 32 - 8 - 56 + 38 - 6 = 0 so x = -2 is a root and (x + 2) is a factor.
(x + 1)(x + 2) = x^2 + 3x + 2.
Long division:
2x^2 - 5x - 3 <-----------Quotient
--------------------------------------------
x^2 + 3x + 2 ) 2x^4 + x^3 -14x^2 - 19x - 6
2x^4 + 6x^3 + 4x^2
-5x^3 - 18x^2 - 19x
-5x^3 - 15x^2 - 10x
-3x^2 - 9x - 6
-3x^2 - 9x - 6
.......................
2x^2 - 5x - 3 = (2x + 1)(x - 3)
So Finally, the factors are (x + 1)(x + 2)(2x + 1)(x - 3).
I am a number less than 100. When you divide me by 2, my remainder is 1. When you divide me by 25, my remainder is 2. What numbers am I?
Answer:
27 and 77
Step-by-step explanation:
Given
Let
[tex]n \to[/tex] number
[tex]n\ \%\ 2 = 1[/tex]
[tex]n\ \%\ 25 = 2[/tex]
[tex]n <100[/tex]
Required
Find n
[tex]n\ \%\ 2 = 1[/tex] implies that the number is odd and the possible solutions are:
[tex]\{3,5,7,9,......99\}[/tex]
The possible solutions to [tex]n\ \%\ 25 = 2[/tex] are:
[tex]\{27,52,77\}[/tex]
Testing 27, 52 and 77 with [tex]n\ \%\ 2 = 1[/tex], we have:
[tex]27\ \%\ 2 = 1[/tex] --- true
[tex]52\ \%\ 2 = 0[/tex] ---- false
[tex]77\ \%\ 2 = 1[/tex] --- true
Hence, the possible numbers are 27 and 77
Solve the following quadratic function
by utilizing the square root method.
Simplify your answer completely.
f(x) = 100 – 49x^2
Answer:
x = 10/7 or x = -10/7
Step-by-step explanation:
By using the completing the squares method, we have to divide the coefficient of the x term by 2, square it and add to both sides
From what we have here, the coefficient of the x term is 0
Thus, we have it that;
0 = 100 - 49x^2
We can proceed to use the difference of two squares here;
Whereby;
a^2 - b^2 = (a-b)(a + b)
0 = (10-7x)(10+7x)
10 - 7x = 0 or 10 + 7x = 0
7x = 10 or 7x = -10
x = 10/7 or x = -10/7
A 200 L tank of water is losing about 120 mL of water a day. If the tank starts off full, how long will it be before it is less than half full?
Answer: 834 days
Step-by-step explanation:
The tank will be half full when it has lost 100 L.
Convert that to milliliters so that it can be compared with the loss rate:
1 l = 1,000 ml
100 l = 100 * 1,000
= 100,000 ml
The rate of loss is 120 ml per day. To lose 100,000 ml, the leak would have to have been going on for:
= 100,000 / 120
= 833.3
= 834 days (less than half full)
