Answer:
y intercept = [tex](0, ~-\frac{5}{2} )[/tex]
x intercept = [tex](-2, ~0)[/tex]
.
Step-by-step explanation:
[tex]-5x - 5y = 10[/tex]
.
y intercept
[tex]\to x = 0[/tex]
[tex]-5(0) - 4y = 10[/tex]
[tex]-4y = 10[/tex]
[tex]y = \frac{10}{-4}[/tex]
[tex]y = -\frac{5}{2}[/tex]
so, the answer is [tex](0, ~-\frac{5}{2} )[/tex]
.
x intercept
[tex]\to y = 0[/tex]
[tex]-5x - 4(0) = 10[/tex]
[tex]-5x = 10[/tex]
[tex]x = \frac{10}{-5}[/tex]
[tex]x = -2[/tex]
so, the answer is [tex](-2, ~0)[/tex]

Henry drank 2/5 of his water bottle. If he drank 3 cups of water, what was the total amount of cups of water in his water bottle? Solve with a model and a full sentence answer.
Answer:
The amount of cups of water in the water bottle is 7.5.
Step-by-step explanation:
Given that Henry drank 2/5 of his bottle of water, and those 2/5 were distributed in 3 glasses, to determine the total amount of glasses that go into the bottle it is necessary to perform the following calculation:
2/5 X = 3
1/5 X = 1.5
X = 1.5 x 5
X = 7.5
Therefore, the bottle fits 7 and a half glasses of water.

Given:
End points a line segment are (9,-8) and (-1,-4).
To find:
The equation of perpendicular bisector of given line.
Solution:
Slope of given line is
[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
[tex]m_1=\dfrac{-4-(-8)}{-1-9}[/tex]
[tex]m_1=\dfrac{-4+8}{-10}[/tex]
[tex]m_1=\dfrac{4}{-10}[/tex]
[tex]m_1=-\dfrac{2}{5}[/tex]
Product of slopes of two perpendicular line is -1.
[tex]m_1\times m_2=-1[/tex]
[tex](-\dfrac{2}{5})\times m_2=-1[/tex]
[tex]m_2=\dfrac{5}{2}[/tex]
So, slope of perpendicular bisector is [tex]\dfrac{5}{2}[/tex].
Perpendicular bisector passes through the midpoint of given endpoints.
[tex]Midpoint=\left(\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2}\right)[/tex]
[tex]Midpoint=\left(\dfrac{9+(-1)}{2},\dfrac{(-8)+(-4)}{2}\right)[/tex]
[tex]Midpoint=\left(\dfrac{8}{2},\dfrac{-12}{2}\right)[/tex]
[tex]Midpoint=\left(4,-6\right)[/tex]
So, perpendicular bisector passes through (4,-6) and having slope [tex]\dfrac{5}{2}[/tex]. The equation of perpendicular bisector is
[tex]y-y_1=m(x-x_1)[/tex]
where, m is slope.
[tex]y-(-6)=\dfrac{5}{2}(x-4)[/tex]
[tex]y+6=\dfrac{5}{2}(x)+\dfrac{5}{2}(-4)[/tex]
[tex]y+6=\dfrac{5}{2}x-10[/tex]
[tex]y=\dfrac{5}{2}x-10-6[/tex]
[tex]y=\dfrac{5}{2}x-16[/tex]
Therefore, the equation of perpendicular bisector is [tex]y=\dfrac{5}{2}x-16[/tex].
Joshua has at most 10 dollars a cab company will charge him 4 dollars flat and a rate is 1.25 for each mile driven write and solve and inequality for the above situation
Answer:
4.8 miles
Step-by-step explanation:
First you need to figure out an equation which will be 10<or equal to 1.25m+4. In this equation m=the number of miles. Knowing this information you can now solve. You want to subtract 4 from both sides leaving you with 6 is less than or equal to 1.25m. You then divide both sides by 1.25 and you are left with 4.8 is less than or equal to m.

State the domain and range of the relation below.
{(1, -2), (4, 5), (2, -4), (6,5), (2, 2)}
A domain = {1, 2, 4, 6) and range = {-4, -2, 2,5}
B domain = {-4, -2, 2, 5} and range = {1, 2, 4, 6}
c domain = {-2, 1, 2, 4, 5} and range = {-4, 2, 2, 5, 6}
D domain = {-4, 2, 2, 5, 6} and range = {-2, 1, 2, 4,5}
* need help fast *
Answer:
The answer you are looking for is A.
Step-by-step explanation:
Remember, the domain is a set of working x values or all possible inputs of a function or two variable relationship. The range is a set of working y values or all possible outputs of a function or two variable relationship. A two variable relationship with more than one output for each input will not be a function in general but will be refered to as inverse.
Now given a set of coordinates for this relation, coordinates with x and y values or inputs and outputs are generally cartesian coordinates represented by (x,y). This is so we know the working x value for each y value, also making it easier to graph it on a coordinate plane or visualize it. x = domain (input of a function) , y = range (output of a function).
All you have to do is sort the x and y values you are given from the coordinates.
For instance, (-1,2) and (4,5) : domain of -1 and 4 [the x values], range of 2, and 5 [the y values].

make m the subject of g-3m=am+5
Answer:
m = (g - 5) / (a + 3)
Step-by-step explanation:
g-3m=am+5
Get all the m's on one side.g - 5 = am + 3m
Combine the m's into one term, using bracketsg - 5 = (a + 3)m
Get m on it's own by dividing by a + 3(g - 5) / (a + 3) = m
Answer:
[tex]\displaystyle m=\frac{g-5}{3+a}[/tex]
Step-by-step explanation:
Equation Solving
To solve an equation for a specific variable, we perform a sequence of steps to have that variable isolated or make it the subject of the equation.
We are given the expression:
[tex]g - 3m=am+5[/tex]
And it's required to make m the subject of the equation. This means we have to isolate m at the left side of the equation.
First, multiply both sides by -1;
[tex]-g + 3m=-am-5[/tex]
Add am:
[tex]-g + 3m+am=-5[/tex]
Add g:
[tex]3m+am=-5+g[/tex]
The variable m is found in both term, thus we factor it out:
[tex]m(3+a)=g-5[/tex]
Dividing by 3+a:
[tex]\mathbm{\displaystyle m=\frac{g-5}{3+a}}[/tex]

can you please explain this?
Answer:
The question is giving you pairs of points in space which can be used to define lines. It is then asking you to determine if the lines defined by those points are parallel, perpendicular, or neither.
Step-by-step explanation:
Two key things you need to know to solve this is that the lines will be parallel if their slopes are the same, and perpendicular if one slope is the negative reciprocal of the other (i.e. [tex]s_{1} = -s_{2}^{-1}[/tex])
Let's start with question 11. You are given two pairs of points, each of which describes a distinct line:
(3,5)-(1,1) and (0, 2)-(5, 12)
To find the slope of each pair, take the vertex with the lesser x co-ordinate, and subtract it from the vertex with the greater x co-ordinate. That will give us a valid Δx and Δy to get the slope.
In the first pair, 3 > 1, so we'll subtract the second point from the first:
[tex]s = \Delta y / \Delta x\\s = \frac{5 - 1}{3 - 1}\\s = 4/2\\s = 2[/tex]
So the first pair of vectors describe a line with a slope of 2. Let's look at the other pair:
[tex]s = \Delta y / \Delta x\\s = (12 - 2) / (5 - 0)\\s = 10 / 5\\s = 2[/tex]
That also gives us a slope of 2, meaning that the two lines are parallel.
This same process will need to be done for the other three questions. We can't answer questions 12 or 14 here, as the last point is cut off on the edge of the image. For question 3 though, one line has a slope of 7/3, and the other 3/7. That puts them in the "neither" category, as one is not the negative reciprocal of the other, but instead the positive reciprocal.

how many ventices are there in a cuboid
8
Step-by-step explanation:
By Euler's formula the numbers of faces F, of vertices V, and of edges E of any convex polyhedron are related by the formula F + V = E + 2. In the case of a cuboid this gives 6 + 8 = 12 + 2; that is, like a cube, a cuboid has 6 faces, 8 vertices, and 12 edges.
Answer:
there are 8 6+8=12+2 vertices, and 12 edges

Given the equation y=-3x+2.5: When x is 1, what value of y makes the equation true? When x is -1.5, what value of y makes the equation true? When y is 8.5, what value of x makes the equation true?
Step-by-step explanation:
when,X=1
y=-3 *1+2.5
y=-3+2.5
y=0.5
when,X=1.5
y=-3*1.5+2.5
y=-4.5+2.5
y=-2
when,y=8.5
8.5=-3*X+2.5
3*X=2.5-8.5
3*X=-6
X=-6/2
X=-3
Hence, the statements are true:
when [tex]x=-1.5[/tex] the value of [tex]y=-2[/tex] and when [tex]y=8.5[/tex] then [tex]x=-3[/tex].
What is the equation?
The definition of an equation is a mathematical statement that shows that two mathematical expressions are equal.
Here given equation is
[tex]y=-3x+2.5[/tex]
So,
[tex]y=-3 (1)+2.5\\y=-3+2.5\\y=0.5\\[/tex]
When,
[tex]x=-1.5\\y=-3(1.5)+2.5\\y=-4.5+2.5\\y=-2\\[/tex]
when,
[tex]y=8.5\\8.5=-3x+2.5\\3x=2.5-8.5\\3x=-6\\x=-\frac{6}{2}\\x=-3\\[/tex]
Hence, the statements are true:
when [tex]x=-1.5[/tex] the value of [tex]y=-2[/tex] and when [tex]y=8.5[/tex] then [tex]x=-3[/tex].

Write the equation of this line in Point-Slope Form.
Answer:
y -3 = (-1/2)(x - 5)
Step-by-step explanation:
Slope of line: Notice that if we go from 7 to 5, the 'run' is -2 and the corresponding 'rise' from 2 to 3 is 1. Thus, the slope is m = -1/2.
Using m = -1/2 and the point (5, 3), we write the equation of this line in point-slope form as:
y -3 = (-1/2)(x - 5)
