Heather is solving an equation by graphing the expressions on either side of the equal sign. If the graph intersects at an infinite number of points which statement could describe the equation heather is attempting to solve?
Answer:
one side of the equation is a quadratic equation, and the other side of the equation is a quadratic expression
Step-by-step explanation:
the description needs to be the same for each equation. For example linear and linear would work as well.
Which is the correct?
Answer:
the 2nd one
Step-by-step explanation:
Given an equation y=-3x +5, explain the steps for using slope-intercept form to graph this equation.
A.Use the y-intercept to plot the point (0,5). Then, using the y-intercept as a reference point move left 3 units and up 1 unit, and plot a second point.
B. Use the y-intercept to plot the point (5,0). Then, using the y-intercept as a reference point, move right 3 units and up 1 unit , and plot a second point.
C.Use the y-intercept to plot the point (5,0). Then, using the y-intercept as a reference point, move left 3 units and up 1 unit, and plot a second point.
D. Use the y-intercept to plot the point (0,5). Then using the y-intercept as a reference point, move left 1 unit and up 3 units, and plot a second point
Answer:
A.Use the y-intercept to plot the point (0,5). Then, using the y-intercept as a reference point move left 3 units and up 1 unit, and plot a second point.
Step-by-step explanation:
5 is the y intercept, so 0,5 is where you would start and then 3 is the same as 3/1 so you go up 3 over 1.

Michelle is a server in a restaurant. On a weekend night, Michelle earned $4 an hour and $65 in tips. She made a total of $93. Write and solve an equation to determine how many hours she worked. On Monday, Ken spent half of his money on a new game. The next day he earned $12 mowing lawns. He now has $32. How much money did Ken have before bought the game? I need the equation too.
Answer:
first question: Michelle worked for 7 hours
second question: Ken had $40 before buying the game
Step-by-step explanation:
4x + 65 = 93
4x = 28, x = 7
Michelle worked for 7 hours
Ken 1/2x + 12 = 32
1/2x = 20
x = 20. 20*2 = $40, ken has $40 before buying the game.
A 10-ounce package of cashews costs $8.11, and a 16-ounce package of cashews costs $12.Calculate the cost per ounce of each package.Which package, the 10-ounce or the 16-ounce package, is the better buy? In the box below write the cost per ounce of each package and state which package is the better buy.
Answer:
The better buy is 12-ounce packageStep-by-step explanation:
Step one:
given data
we are told that 10 ounces cost $8.11
and also 16 ounces cost $12
Required
The unit cost per ounce
for the 10 ounce package
the unit cost = 8.11/10=$0.81 per ounce
for the 12 ounce package
the unit cost = 12/16=$0.75 per ounce
the better buy is 12-ounce package because the unit cost is cheaper than that of the 10-ounce package by $0.06
factor 2w+6
Please explain? I'd like to understand how you did it so that I can do it myself the next time, thanks a mil :)
Answer:
2( w + 3 )
Step-by-step explanation:
Well first off, since theres no common term to factor out, I had to split 6 in half
so 2 w + 6 becomes 2w + 2 x 3.
I then factored out 2 because it's a common term,
which then leaves: 2( w + 3 )
basically, you have to find a common term to factor out, if you don't see one, you have to do something to a number so there's common terms.

What is the unit rate if you write 11 pages in 2 hours? F What is the unit rate If you write 11 pages in 2 hours
Answer:
5.5 pages/hour
Step-by-step explanation:
We need to find the unit rate if you write 11 pages in 2 hours. It can be calculated by dividing no of pages to no of hours as follows :
[tex]R=\dfrac{11}{2}\ \text{pages/hour}\\\\=5.5\ \text{pages/hour}[/tex]

2. Si Maria decide recortar rectangulos, de área igual a 0.03 m?, ¿Cuántos rectángulos obtendrá de la cartulina?
a) 6 rectangulos
b) 60 rectangulos
c) 15 rectangulos
150
d)
rectángulos
Responder:
60 triángulos
Explicación paso a paso:
La pregunta está incompleta. No se dio el área del cartón. Digamos que la dimensión del cartón es de 2 m por 0,9 m.
Área del cartón = Largo * Ancho
Dado;
Longitud = 2 m
Ancho = 0,9 m
Área del cartón = 2 * 0.9
Área del cartón = 1.8m²
Si María decide recortar rectángulos con un área igual a 0.03 m², la cantidad de rectángulos que puede obtener del tablero se expresa como;
Número de rectángulos = área del cartón / área de cada parte recortada
Número de rectángulos = 1.8 / 0.03
Número de rectángulos = 60 rectángulos.
Por tanto, el número de rectángulos que puede recortar es de 60 rectángulos.
Tenga en cuenta que se asumió el área del rectángulo y que se puede emplear el mismo cálculo para cualquier otra dimensión dada.
How many grade seven students of koronadal national comprehensive high school are there in all
The complete question is;
The following diagram(attached) shows how all the Grade Seven students of
Koronadal National Comprehensive High School go to school.
How many grade seven students of koronadal national comprehensive high school are there in all
Answer:
269 students
Step-by-step explanation:
From the venn diagram attached, we can see various given numbers of the students of the different modes of transport to school.
To get how many grade 7 students there are in total, we will add all the students inside the venn diagram simply because the set of grade 7 students are represented by those inside the venn the venn diagram while the number 100 outside the venn diagram is not a member of the set of grade 7 students which we are dealing with.
Thus,
Total number of grade 7 students = 76 + 19 + 15 + 17 + 55 + 20 + 67 = 269

What is the measure of AC?
DE is 30, so AD is also 30
A full circle is 360
ACE = 360- Ad-de
Ace = 360-30-30 = 300
Ac is half of ace
Ac = 300/2 = 150
The answer is b 150

9514 1404 393
Answer:
see attached
Step-by-step explanation:
If you plot the points on the graph, you notice that the run (change in x) is 3 for each "rise" (change in y) of -1, so the slope is ...
m = rise/run = -1/3
The middle point is on the y-axis, so is the y-intercept.
In slope-intercept form, the equation is ...
y = mx + b . . . . . . where m is the slope (-1/3) and b is the y-intercept (4)
y = -1/3x +4 . . . . equation
-62 - 4x = 42
So how do I get the answer to this problem?
Answer:
-26
Step-by-step explanation:
-62 - 4x = 42
-4x=42+62
-4x=104
X=-104/4
X=-26
So the value of the X is -26
Max placed 6 cans in a box and the box was 40% full.How many cans will the box be able to hold when it’s completely full?
Answer:
4 cans
Step-by-step explanation:
this can be 4 cans because if 6 cans equal 40% it's opposite so 4 cans equal 60% so full is 100% so 60%+40%=100%
Erin weighs 135 pounds and is gaining ½ pound each week. Miranda weighs 143 pounds and is losing ¼ pound each week. Write an equation that could be used to determine x, the number of weeks that it will take until the two girls weigh the same amount?
Answer:
10.66 weeksStep-by-step explanation:
Number of weeks is x
135 + 1/2x = 143 - 1/4x1/2x + 1/4x = 143 - 1353/4x = 8x = 32/3 = 10.66 weeksAnswer:
[tex]135+\frac{1}{2}x=143-\frac{1}{4}x[/tex]
Step-by-step explanation:
Let E represent Erin’s weight, and let M reprevent Miranda’s weight.
And let x represent the amount of week that passes.
Eric is currently 135 pounds. However, she is gaining 1/2 pounds per week x.
Hence, we can write the following equation:
[tex]D=135+\frac{1}{2}x[/tex]
Miranda currently weights 143 pounts. However, she is losing 1/4 pounds per week x.
Since she is losing weight, 1/4 is negative. Hence:
[tex]M=143-\frac{1}{4}x[/tex]
When the two girls weigh the same, D=M. Thus:
[tex]D=M[/tex]
Substitute them for their respective equations to acquire:
[tex]135+\frac{1}{2}x=143-\frac{1}{4}x[/tex]
Notes:
To solve, first eliminate the fractions by multiplying everything by 4. This yields:
[tex]540+2x=572-x[/tex]
Add x to both sides. Subtract 540 from both sides:
[tex]3x=32[/tex]
Divide both sides by 3:
[tex]x=32/3\approx10.67[/tex]
Hence, it will take about 11 weeks for the girls to weigh the same.

If Triangle ABC is congruent to Triangle SRT, find the possible value(s) for x
Answer:
x = 2 or x = -3
Step-by-step explanation:
Given that ∆ABC ≅ ∆SRT, it follows that their corresponding side lengths are congruent to each other.
Thus:
[tex] RT = BC [/tex]
[tex] (x^2 + x) = 6 [/tex]
Solve for x
[tex] x^2 + x = 6 [/tex]
Subtract 6 from each side
[tex] x^2 + x - 6 = 6 - 6 [/tex]
[tex] x^2 + x - 6 = 0 [/tex]
Factorise
[tex] x^2 + 3x - 2x - 6 = 0 [/tex]
[tex] x(x + 3) -2(x + 3) [/tex]
[tex] (x - 2)(x + 3) [/tex]
x = 2 or x = -3
