Answer:
A. Add -2 to both sides
Step-by-step explanation:
The reason you need to add -2 to both sides is because if you add -2 to -2 it cancels out and you are left with x=18. But you need to add -2 to 18 too because them the equation won't be equal anymore.

Bailey made risotto using a recipe that called for 223 cups of liquid. Bailey added 23 cup of liquid to the risotto every 10 minutes. Drag and drop to complete the equation to find how many times Bailey added 23 cup of liquid.
Answer:
4 times
Step-by-step explanation:
Given that :
Cups of liquid required = 2 2/3
Fraction of liquid cup added per 10 minutes = 2/3
The number of times 2/3 cups of liquid is added :
Total cups of liquid required / amount of liquid added at a time
2 2/3 ÷ 2/3
8/3 ÷ 2/3
8/3 * 3/2
24 / 6
= 4 times

-2/5 w+11 2/5=9 4/5 solve for w please
Answer:
w = 4.
Step-by-step explanation:
-2/5 w+11 2/5=9 4/5
-2/5w + 57/5 = 49/5
Remove the fractions by multiplying thru by 5:
-2w + 57 = 49
-2w = 49 - 57
-2w = -8
w = 4.
Answer:
w= -8/5

The area of a trapezium is 300sqm and its height is 10m, if one of the parsllel sides is 10m, the length of the other parallel side is
Answer:
50M
Step-by-step explanation:
The area of a trapezium = 1/2 x ( a + b) x h
a and b are the parallel sides
h = height
300sqm = 0.5 x (10 + b) x 10
divide both sides by 10
30 = 0.5 x (10 + b)
Divide both sides by 0.5
60 = (10 + b)
b = 60 - 10 = 50
What's the equation
Given:
The graph of a parabola.
To find:
The equation for the parabola.
Solution:
The vertex form of a parabola is:
[tex]y=a(x-h)^2+k[/tex] ...(i)
Where, a is a constant and (h,k) is the vertex.
From the given graph it is clear that the vertex of the parabola is at point (-1,6). So, h=-1 and k=6.
Putting h=-1 and k=6 in (i), we get
[tex]y=a(x-(-1))^2+(6)[/tex]
[tex]y=a(x+1)^2+6[/tex] ...(ii)
The y-intercept of the graph is at point (0,3). Putting x=0 and y=3 in (ii), we get
[tex]3=a(0+1)^2+6[/tex]
[tex]3-6=a[/tex]
[tex]-3=a[/tex]
Putting a=-3 in (ii), we get
[tex]y=-3(x+1)^2+6[/tex]
Therefore, the equation of the parabola is [tex]y=-3(x+1)^2+6[/tex].
Write a polynomial function rule for g(x)+f(x)
Consider the polynomial function
f(x)=7x^3+x2-4x+10
g(x)=c^2-5
Given:
Consider the given polynomials are:
[tex]f(x)=7x^3+x^2-4x+10[/tex]
[tex]g(x)=x^2-5[/tex]
To find:
The polynomial function rule for [tex]g(x)+f(x)[/tex].
Solution:
We need to add both functions to get [tex]g(x)+f(x)[/tex].
[tex]g(x)+f(x)=(x^2-5)+(7x^3+x^2-4x+10)[/tex]
[tex]g(x)+f(x)=x^2-5+7x^3+x^2-4x+10[/tex]
On combining like terms, we get
[tex]g(x)+f(x)=7x^3+(x^2+x^2)-4x+(10-5)[/tex]
[tex]g(x)+f(x)=7x^3+2x^2-4x+5[/tex]
Therefore, the required function is [tex]g(x)+f(x)=7x^3+2x^2-4x+5[/tex].
Drag each graph to the correct location on the table.
The points on the graphs represent relations. Classify these relations according to whether or not they are functions
Answer:
Functions: Second Graph
Not functions: first and third graph
Step-by-step explanation:
The first and third graph are not functions and the second graph is a function. Use the vertical line test. I'm 100% sure.
By the vertical line test, it's clear that graph first will not be a function, second will be a function and third will also not be a function.
What is the e-test?A vertical line test is a test to determine whether a given function is a function or not.
In the vertical line test, we draw a vertical line on every x's point if the line intersects with only a single value of corresponding y then it will be a function otherwise not.
In the first given function if we draw a vertical line at x = 2 then it gave different values corresponding to y hence, it will not a graph.
In the second given function by drawing a vertical line, it gave a single unique value so it will be a function.
In the third given function if we draw a vertical line at x = 1 and 2 then it gives different values corresponding to y hence, it will not be a graph.

I believe (x+5)(x-2) would be equal though.
Step-by-step explanation:
(x-5)(x+2) = x²+2x-5x-10
simplify:
x²-3x-10 ≠ x²+3x-10
(x)(x+3) = x²+3x
simplify:
x²-3x ≠ x²+3x-10
(x+3)(x-10) = x²-10x+3x-30
simplify:
x²-7x-30 ≠ x²+3x-10
Jivesh brought his Model B rocket on a camping trip near the top of a mountain. He wants to model how it descends down the mountain. Here, he uses the equation h = −640t^2. When has the rocket descended 1,690 centimeters? Round your answers to the nearest hundredth. After t ≈ seconds, the rocket will have descended a distance of 1,690 centimeters. The negative time (can, cannot) be used in this context.
Answer:
i. 1.63 s
ii. The negative time cannot be used in this context
Step-by-step explanation:
i. Since h = −640t² and the rocket descends 1,690 m, h = -1,690 m (since there is a drop in height).
So, h = -640t²
t² = h/-640
t = √(- h/640)
Substituting h into the equation, we have
t = √(- h/640)
t = √[-(-1,690)/640]
t = √2.640625
t = 1.625
t ≈ 1.63 s
ii. So, the negative time cannot be used in this context because, the height drop is negative.

Step-by-step explanation:
To solve this problem use proportions. The tree's proportion is equal to [tex]\frac{30}{40}[/tex] and the shed's proportion is [tex]\frac{15}{x}[/tex]. These proportions are made by putting the height of the object over the length of the shadow. Then, cross multiply to find x. Do this by multiplying [tex]30 *x[/tex] and [tex]40*15[/tex]. Next set these equal to each other, [tex]30x=600[/tex]. Finally, divide both sides by 30 to find x. This equals 20 feet.

Find the length of side x I simplest radical form
Answer:
Option A
Step-by-step explanation:
By applying Pythagoras theorem in ΔABC,
(Hypotenuse)² = (Leg 1)² + (Leg 2)²
AC² = AB² + BC²
AC² = 6² + 5²
AC = [tex]\sqrt{61}[/tex]
Similarly, by applying Pythagoras theorem in ΔACD,
AD² = AC² + CD²
(10)² = [tex](\sqrt{61})^2[/tex] + x²
x² = 100- 61
x² = 39
x = √(39)

A major credit card company requires monthly payments equal to or greater than 8% of the total balance.A consumer has a credit card balance of $320. Write an inequality that represents acceptable payment amounts.
Answer:
320 x 0.08 = X
In the case, a payment equal to or greater than $ 25.60 would be considered acceptable by the company.
Step-by-step explanation:
Given that a major credit card company requires monthly payments equal to or greater than 8% of the total balance, and a consumer has a credit card balance of $ 320, the following calculations must be performed to determine an inequality that represents acceptable payment amounts:
320 x 0.08 = X
25.6 = X
Thus, in the case, a payment equal to or greater than $ 25.60 would be considered acceptable by the company.
Please help. Find the area of the composite figure
Okay so multiple 17 times 8 and 16 times 33 and then add the answers together and you should get 664!
Step-by-step explanation:
here's your solution
=> Firstly divide above picture in two parts
=> 1st = traingle
=> 2nd = trapezium
=> area of traingle = 1/2*base*height
=> height = 8
=> we need to find out base by using Pythagoras formula
=> base^2 = 17^2 - 8^2
=> base^2 = 289 - 64 = 225
=> base = √225
=> base of traingle = 15
=> now, area of traingle = 1/2*15*8
=>60sq.units
=> area of trapezium = 1/2(sum of p. sides ) *
distance between them
=> area = 1/2*(33 + 15)*16
=> area = 1/2*16*48
=> area = 384sq.units
=> area of whole figure = 384 + 60
= 444 sq.units
Nina buys a small rug in the shape of a kite. The width of the rug is half its height. What are the width and the area of the rug
Answer:
Width = 1/2h
Area = 1/4h²
Step-by-step explanation:
This is quite a vague question from you. Being asked to find the width and area of a particular shape, without being given dimensions.
However, I would try to solve it nonetheless.
From your question, you stated that the width of the rug is half its height, if so, then,
w = 1/2h
Again, you're being asked to find the area. Area of a kite is given as
Area = 1/2 * Width * Height and as such, we have
Area = 1/2 * 1/2h * h
Area = 1/4 * h²
All that you need to do now is substitute the value of h
