linear equation: -3(x+4)+5x=3(-2x-4) +8x
Answer:
-52
Step-by-step explanation:
I haven't learnt these types of things yet, just decided to give it a try.
Answer:
0 = 0
Step-by-step explanation:
Q= -3(x + 4)+5x = 3(-2x-4)+8x
first : -3 multiply both x and 4 and 3 multiply both -2x and -4
then : -3x-12+5x = -6x-12+8x
and then collect like terms ; -3x+5x -12= -6x+8x-12
= 2x -12 = 2x-12
finally, 2x-2x = -12+12
0 = 0

what’s the degree
Answer:
Finding the degree of a polynomial is really simple. All you have to do is find the largest exponent in the polynomial, so in this case, the degree is 5 (Yes, my previous answer is wrong) and not 26. I don't know how you got 26.
Another example: In 3x² - 8x⁷ + 6xy⁴, the degree is 7.

for the third question The equation of the parabola is y^2 = 8x
Step-by-step explanation:
The equation for the parabola is y² = 4px, the equation of the directrix is x = -2, the focus is at (2, 0), and the value of p is 2.
What is a parabola?It is defined as the graph of a quadratic function that has something bowl-shaped.
(x - h)² = 4a(y - k)
(h, k) is the vertex of the parabola:
a = √[(c-h)² + (d-k²]
(c, d) is the focus of the parabola:
It is given that:
From the graph the equation will be:
y² = 4px
The focus is (2, 0)
As the directrix is x = -2
The value of p = 2.
Thus, the equation for the parabola is y² = 4px, the equation of the directrix is x = -2, the focus is at (2, 0), and the value of p is 2.

Johanna sells small cakes for $60 and large cakes for $80. She earned $1200 in sales one day. Johanna found that she could represent this situation with the equation
60x+80y=1200
where x is the number of small cakes and y is the number of large cakes.
If this equation is rewritten as a function by solving for y, what would be a reasonable domain for that function?
Answer:
[tex]0 \le x \le 20[/tex]
Step-by-step explanation:
Given
[tex]60x + 80y = 1200[/tex]
Required
Determine the domain
[tex]60x + 80y = 1200[/tex]
First, solve for y
[tex]80y = 1200 - 60x[/tex]
Divide through by 80
[tex]\frac{80y}{80} = \frac{1200}{80} - \frac{60x}{80}[/tex]
[tex]y = \frac{1200}{80} - \frac{60x}{80}[/tex]
[tex]y = 15- 0.75x[/tex]
Given that x represents large cakes
The smallest number of cakes is 0.
To get the largest, we simply set y to 0 (to get the x intercept)
[tex]0 = 15- 0.75x[/tex]
[tex]-15 = - 0.75x[/tex]
Solve for x
[tex]x = \frac{-15}{-0.75}[/tex]
[tex]x = 20[/tex]
Hence, the domain is:
[tex]0 \le x \le 20[/tex]

Find the slope of each line
Step-by-step explanation:
To find the Slope of each line, pick two points you can clearly identify on each graph. The first graph has a point (-5,5) and (4,-5). Using these two points find the difference of the y coordinates divided by the difference in the x coordinates, like this:
5 - (-5). = 10
-5 - 4 = - 9
So the Slope is - 10/9
Same steps for all. Your equation is
(y1 - y2) / (x1 - x2)
Mia drew a map of a park. Mia’s map shows the endpoints of the walking paths at A(2, 2), B(2, 6), C(8, 6), and D(8, 2). There are 6 walking paths: AB, BC, CD, AD, AC, and BD.
1. Are walking paths AB and CD parallel? Explain.
2. Are walking paths AC and BD perpendicular? Explain.
3. Mia also drew path FG that goes through (12, 2) on her map and is parallel to path AC. Write an equation for path FG.
4. Mia also drew path MN that goes through (10, 10) on her map and is perpendicular to path BD. Write an equation for path MN.
Answer:
1. yes, because they both have the same undefinite slopes. They are both vertical lines.
2. no, because their slopes are not negative reciprocals.
3. [tex]y=\frac{2}{3}x-6[/tex]
4. [tex]y=\frac{3}{2}x+5[/tex]
Step-by-step explanation:
In order to solve this problem, we can start by drawing a diagram of the paths Mia drew. (See attached picture the red lines are the original paths).
1. In order to determine if the paths are parallel or not, we need to first know what the slope of the paths is. The slope of the paths can be found by using the equation:
[tex]m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]
So, for path AB we get:
[tex]m_{AB}=\frac{6-2}{2-2}[/tex]
which yields:
[tex]m_{AB}=\frac{4}{0}[/tex]
Now, since we have a denominator of 0 in that friction, this means that the division is not defined for the real number, therefore, we are dealing with a vertical line.
for the path CD we get:
[tex]m_{CD}=\frac{2-6}{8-8}[/tex]
which yields:
[tex]m_{AB}=-\frac{4}{0}[/tex]
Now, since we have a denominator of 0 in that friction, this means that the division is not defined for the real number, therefore, we are dealing with a vertical line.
Therefore, since both slopes are the same, this means that the two lines will be parallel.
2. The procedure is the same as in the previous problem:
[tex]m_{AC}=\frac{6-2}{8-2}[/tex]
which yields:
[tex]m_{AC}=\frac{2}{3}[/tex]
for the path BD we get:
[tex]m_{BD}=\frac{2-6}{8-2}[/tex]
which yields:
[tex]m_{BD}=-\frac{2}{3}[/tex]
This two fractions are just opposite in sign. But for the lines to be perpendicular, their slopes should be negative reciprocal. In this case they are not reciprocal, so the lines are not perpendicular to each other.
3. For part 3, we know that for two lines to be parallel, their slopes must be the same. We already found the slope of AC to be:
[tex]m_{AC}=\frac{2}{3}[/tex]
we also know the line must go through the point (12,2), so we can use the point-slope form of the equation:
[tex]y-y_{1}=m(x-x_{1})[/tex]
so we can go ahead and substitute the pertinent data:
[tex]y-2=\frac{2}{3}(x-12)[/tex]
So now we can solve it for y so it gets the slope-intercept form, which is:
[tex]y=\frac{2}{3}x-6[/tex]
4. In this part of the problem, we will need to follow a similar process, but this time, we need the slope to be negative reciprocal to slope of the line BD.
[tex]m_{BD}=-\frac{2}{3}[/tex]
so:
[tex]m_{MN}=\frac{3}{2}[/tex]
so now we can build our equation with the point-intercept form and the given point so we get:
[tex]y-10=\frac{3}{2}(x-10)[/tex]
So now we can solve it for y so it gets the slope-intercept form, which is:
[tex]y=\frac{3}{2}x-5[/tex]

a motor bike travels 240 km in 4 hours. How long will it take to travel 450 km
Answer:
7 hours and 30 minutes
Step-by-step explanation:
[tex]240 \div 4 = 60km \: per \: h[/tex]
[tex]450 \div 60 = 7.5 = 7h \: 30min[/tex]
It will take motor bike 7.5 hours to cover 450 Km of distance.
What is Speed in Kinematics?Speed of a body is defined as the distance travelled by it per unit time taken to cover the distance.
Mathematically-
S = Δd/Δt or S = {d(2) - d(1)}/{t(2) - t(1)}
It is a scalar quantity as it only has magnitude and no direction.
Given is a motor bike travels 240 km ins 4 hours.
We can calculate the speed of the bike as -
s = 240/4 = 60 Km/hr
Then, the time taken to cover 450 Km will be -
t = 450/60
t = 7.5 hours
Therefore, it will take motor bike 7.5 hours to cover 450 Km of distance.

To solve the system of linear equations 3 x minus 2 y = 4 and 9 x minus 6 y = 12 by using the linear combination method, Henry decided that he should first multiply the first equation by –3 and then add the two equations together to eliminate the x-terms. When he did so, he also eliminated the y-terms and got the equation 0 = 0, so he thought that the system of equations must have an infinite number of solutions. To check his answer, he graphed the equations 3 x minus 2 y = 4 and 9 x minus 6 y = 12 with his graphing calculator, but he could only see one line. Why is this? because the system of equations actually has only one solution because the system of equations actually has no solution because the graphs of the two equations overlap each other because the graph of one of the equations does not exist
Answer:
because the graphs of the two equations overlap each other
Step-by-step explanation:
when two graphs have the same line, the line overlaps so it looks like only one line. therefore, the answer is
C) because the graphs of the two equations overlap each other.

Hey there!
“66 / v = 44 / 62”
~ FIRST you have to CROSS MULTIPLY
66 • 62 = 44 • v
66 • 62 = 4,092
44 • v = 44v
➡️ 4,092 = 44v
~ SECOND TURN/FLIP your EQUATION
44v = 4,092
~ THIRD DIVIDE both SIDES by 44
44v / 44 = 4,092 / 44
CANCEL out: 44 / 44 because that gives you 1
KEEP: 4,092 / 44 because that gives you the v-value
FOURTH: SOLVING
4,092 / 44 = v ; v = 4,092 / 44
Solve the equation that’s in STEP FOUR and you have your v-value
