The difference of the square of a number and 18 is equal to 3 times that number. Find the positive solution.
Answer: x=6 or x=-3
Step-by-step explanation:
x^2-18=3x
x^2-3x-18=0
(x-6)*(x+3)=0
x-6=0 x+3=0
x=6 x=-3

. Is (4,-3) a solution to the following system of equations?
X - y = 4
2x + y = 5
(Use elimination method)
Answer:
No. The correct solution is (3,-1)
Step-by-step explanation:
Since we are using elimination method, we can go ahead and see that we can cancel "-y" from the first equation and "+y" from the second equation.
Once we do that, we go ahead add the like terms and get 3x = 9
Then, we divide by 3 on each side and get x = 3
Now, we can take that value of x and plugin to any of the original 2 equations we started with.
Say we plugin x = 3 into the second equation.. it will turn to, 2(3) + y = 5
Then we solve for y.
2(3) + y = 5
6 + y = 5
6 - 1 = 5
y = -1
There, we found our x value and our y value, (3,-1) :)

The two angles are supplementary angles, which when added together equal 180 degrees.
6x -10 + 6x +10 = 180
Combine like terms:
12x = 180
Divide both sides by 12:
x = 180/12
x = 15
The answer is C) 15

Between which two integers does -√46 appear on the number line please write in words
==========================================================
Explanation:
List out the perfect squares
1^2 = 12^2 = 43^3 = 94^2 = 165^2 = 256^2 = 367^2 = 498^2 = 64and so on. We can see that 46 is between 6^2 = 36 and 7^2 = 49.
We can say 6^2 < 46 < 7^2
Applying the square root to all three sides leads us to 6 < sqrt(46) < 7
Now multiply all three sides by -1. This will flip the inequality signs
We go from
6 < sqrt(46) < 7
to
-6 > -sqrt(46) > -7
It might help to order things from smallest to largest to get this
-7 < -sqrt(46) < -6
This means -sqrt(46) is between -7 and -6 on the number line
See the diagram below.
Answer:
Step-by-step explanation:
First notice that -√46 lies between -√49 and -√36, that is, between
-7 and -6.
Here all three numbers are negative because they lie to the left of zero (0) on the number line.

Answer:2.3
Step-by-step explanation:
Cut the the shape into a right triangle and a rectangle
Tri: find measure of the base
sin(45)= opp/hyp
= x/1.8
1.8 *sin (45) = x
x = 1.3
base of tri = 1.3
Area of tri = 1/2bh
1/2(1.3)(1.3)
=0.845
Area of rectangle: 1.1*1.3=1.43
Total area = 1.43+0.845
=2.245
=2.3m^2

In simple fraction= 3/2
DIvide 3/2 by 2
= 3/2/3
=3/2 * 1/3
=3/6
= 1/2
Hence each person will get 1/2 of the whole water melon

Answer:
area = 2.28
Step-by-step explanation:
area of triangle is 1/2*b*h
area = (1/2)*3.8*1.2
area = 2.28
Answer:
2.28
Step-by-step explanation:
Area of triangle =(base*height)/2
And base=1.2 cm
Height=38 mm ( change it to cm as they need the answer in square cm) which is 3.8 cm
So (1.2*3.8)/2=2.28
Tom bought a pizza. He ate 1/3 of the pizza and gave some of it to his brother. He was left with 1/5 of the pizza. What fraction of the pizza did he give to his brother?
Answer:
2/3 = 10/15
1/5 = 3/15
10/15 - 3/15 = 7/15 of the pizza to his brothers
Suzie's Slushes has increasing profits each week during the hot summer months. Suzie finds that each week during the summer her profits increase by 30% over what they were the previous week. In her first week of business, her profits were $300.
How much money will she make in all over 4 weeks?
Enter your answer, rounded to the nearest cent, in the box.
HELP FAST PLEASE
Answer: 1856.10
Step-by-step explanation:
Suzie will make $1856 in 4 weeks.
Suzie will make a profit of:The first week 300
The second week: 300 x 30% + 300 = 390
The third week: 390x (1430%) = 507
The fourth week: 507 × (1430%) = 659.1
So Sum to: 300 +390 +507 +659.1 = 1856.1
Profit is $1856.

I NEED HELP WITH A MATH QUESTION!!! graph and vertex are included
Answer:
Below
Step-by-step explanation:
To find the answers for the table, you must plug in each x value into the equation and get your y value:
x = -1
(-1^2)-(4*-1)-1
=
1+4-1
=
4
When x = -1, y = 4
x=0
(0^2)-(-4*0)-1
=
-1
When x = 0, y = -1
x = 1
(1^2)-(4-1)-1
=
1-4-1
=
-4
When x = 1, y = -4
x = 2
(2^2)-(4*2)-1
=

=
-5
When x = 2, y = -5
x = 3
(3^2)-(4*3)-1

Which is the correct formula for the function?
35% of customers at a clothing store spend at least $20 per visit. Yesterday, 143 spent at least $20. Predict the number of customers who came to the store yesterday.
Answer:do 142 times 20 which is 2840 times 0.35 which is 994 I think not sure
Step-by-step explanation:
Answer:
Total number of customers = 143/35% = 409 approximately
Step-by-step explanation:
If the trend did not change yesterday, we estimate that 143 customers constitute 35% of the total number.
So
Total number of customers = 143/35% = 409 approximately
Can anyone help me solve this circle?
=============================================
Explanation:
Focus on triangle OCT. We can see that the triangle is isosceles because OT = OC are two radii of the same circle. That consequently means angles T and C are the congruent base angles (rotate the triangle to see what I mean). The base angles are opposite the congruent sides.
Since base angle C is 35 degrees, that makes base angle T this measure as well.
-----------
We just found angle CTO is 35 degrees. Angle PTO is supplementary to this, so it is 180-35 = 145 degrees.
Now focus solely on quadrilateral PTOQ. The goal is to find angle O, aka angle QOT. We found angle T in the paragraph above and it's 145 degrees. Angle Q is 90 degrees assuming segment PR is tangent to the circle at point Q.
------------
Recall that for any quadrilateral, the interior angles always add to 360
let x be the measure of angle O, aka angle QOT
P+T+O+Q = 360
60+145+x+90 = 360
x+295 = 360
x = 360-295
x = 65
Therefore, angle QOT is 65 degrees

Tao uses elimination to solve the following system of linear equations.
Given:
The system of equation is:
[tex]-2x+4y=16[/tex]
[tex]2x+2y=8[/tex]
To find:
The solution of the given system of equations.
Solution:
We have,
[tex]-2x+4y=16[/tex] ...(i)
[tex]2x+2y=8[/tex] ...(ii)
Add (i) and (ii) to eliminate the variable x.
[tex]6y=24[/tex]
[tex]y=\dfrac{24}{6}[/tex]
[tex]y=4[/tex]
Putting [tex]y=4[/tex] in (ii), we get
[tex]2x+2(4)=8[/tex]
[tex]2x+8=8[/tex]
[tex]2x=8-8[/tex]
[tex]2x=0[/tex]
Divide both sides by 2.
[tex]x=0[/tex]
Therefore, the solution of given system of equations is (0,4). Hence, the correct option is A.
Answer:
(0,4) or A
