What is the solution for x in the equation? -4 + 5x - 7 = 10 + 3x - 2
Answer:
x = 9.5
x = 9 1/2
x = 19/2
All answers are the same, just different ways of denoting it.
Step-by-step explanation:
-4 + 5x - 7 = 10 + 3x - 2
Simplify both sides, by combining like terms
-4 + 5x - 7 = 10 + 3x - 2
-11 + 5x = 8 + 3x
Inverse operations
-11 + 5x = 8 + 3x
+11 +11
5x = 19 + 3x
-3x -3x

Please answer 4x + 10 = 30
Answer:
x=5
Step-by-step explanation:
Let's solve your equation step-by-step.
4x+10=30
Step 1: Subtract 10 from both sides.
4x+10−10=30−10
4x=20
Step 2: Divide both sides by 4.
4x /4 = 20/4
x=5
The value of x that satisfies the equation 4x + 10 = 30 is x = 5.
Here,
To solve the equation 4x + 10 = 30,
we want to find the value of x that makes the equation true.
Step 1: Isolate the variable term.
First, we want to get rid of the constant term 10 on the left side of the equation.
We can do this by subtracting 10 from both sides of the equation:
4x + 10 - 10 = 30 - 10
Simplifying:
4x = 20
Step 2: Solve for x.
Next, we want to isolate the variable x on one side of the equation.
Since 4 is multiplied by x, we can undo this by dividing both sides of the equation by 4:
4x / 4 = 20 / 4
Simplifying:
x = 5
Step 3: Check the solution.
To verify that our solution is correct, we can substitute the value of x back into the original equation:
4x + 10 = 30
Substitute x = 5:
4(5) + 10 = 30
Simplifying:
20 + 10 = 30
30 = 30
Since both sides are equal, our solution x = 5 is correct.
Therefore, the value of x that satisfies the equation 4x + 10 = 30 is x = 5.

Find a function rule for the line that passes through the origin (0,0) and the point (5, - 13)
what is the function rule for the line?
a. y= -13/5x
b. y= -5/13x
c. y= 5x -13
d. y= -13x +5
Answer:
The Function rule for line is: [tex]\mathbf{y=-\frac{13}{5}x}[/tex]
Option A is correct option.
Step-by-step explanation:
Find a function rule for the line that passes through the origin (0,0) and the point (5, - 13)
The function rule is of form: [tex]\mathbf{y=mx+b}[/tex]
where m is slope and b is y-intercept
Finding slope:
The formula used to find slope is: [tex]Slope=\frac{y_2-y_1}{x_2-x_1}[/tex]
We have [tex]x_1=0, y_1=0, x_2=5, y_2=-13[/tex]
Putting values and finding slope
[tex]Slope=\frac{y_2-y_1}{x_2-x_1}\\Slope=\frac{-13-0}{5-0}\\Slope=\frac{-13}{5}\\Slope=-\frac{13}{5}[/tex]
Finding y-intercept
We will use point(0,0) to find y-intercept
[tex]y=mx+b\\0=-\frac{13}{5}(0)+b\\0=0+b\\b=0[/tex]
So, y-intercept is 0
The Function rule for line having slope m=-13/5 and y-intercept b=0:
[tex]y=mx+b\\y=-\frac{13}{5}x+0\\y=-\frac{13}{5}x[/tex]
So, The Function rule for line is: [tex]\mathbf{y=-\frac{13}{5}x}[/tex]

A 17 year old female high school student feels that she is overweight. Her weight is 145 and height 5'4. Calculate the BMI. Round your answer to one decimal place.
Answer:
BMI is 24.9
Step-by-step explanation:
In order to calculate the student's BMI we first need to convert her weight into kilograms and her height into meters. We know that there are 39.37 inches in a meter and every foot has 12 inches. Therefore, since the student is 5ft 4 inches, this means she is 64inches tall. Now we can divide this by 39.37 to find her height in meters
64 / 39.37 = 1.6256 meters
Now we need to calculate her weight in kilograms. Since there are 2.20462 pounds in 1 kilogram, we simply divide her weight by 2.20462.
145 / 2.20462 = 65.7709 kilograms
Now we use the BMI formula to solve for the students BMI
BMI = [tex]\frac{mass}{height^{2} }[/tex]
BMI = [tex]\frac{65.7709}{1.6256^{2} }[/tex]
BMI = [tex]\frac{65.7709}{2.6425}[/tex]
BMI = 24.88
Therefore we can see that the students BMI is 24.9

What are the coordinates of the point on the directed line segment from
(-6, -10) to (9, 2) that partitions the segment into a ratio of 1 to 2?
Answer:
The coordinates of point that divides the given line in ratio 1:2 are (-1,-6)
Step-by-step explanation:
Given that:
(x1,y1) = (-6,-10)
(x2,y2) = (9,2)
If a point (x,y) divides a line into ratio m:n, the coordinates can be found out by the formula
[tex](x,y) = (\frac{nx_1+mx_2}{m+n} , \frac{ny_1+my_2}{m+n})[/tex]
As given ratio is: 1:2
so m= 1
n = 2
Putting the values in the formula we get
[tex]= (\frac{(2)(-6)+(1)(9)}{1+2} , \frac{(2)(-10)+(1)(2)}{1+2})\\=(\frac{-12+9}{3} , \frac{-20+2}{3})\\=(\frac{-3}{3} , \frac{-18}{3})\\=(-1,-6)[/tex]
Hence,
The coordinates of point that divides the given line in ratio 1:2 are (-1,-6)

Part b
What is the y-intercept of the function
Answer:
A. [tex]f(n) =0.2n+4.8[/tex]
B. The y intercept is 4.8
Step-by-step explanation:
Given
[tex]a_n= 5 + 0.2(n-1)[/tex]
Solving (a): Write as a function.
To do this, we simply substitute f(n) for [tex]a_n[/tex]
[tex]a_n= 5 + 0.2(n-1)[/tex] becomes
[tex]f(n)= 5 + 0.2(n-1)[/tex]
Open Bracket
[tex]f(n) = 5 + 0.2n-0.2[/tex]
Collect Like Terms
[tex]f(n) =0.2n-0.2 + 5[/tex]
[tex]f(n) =0.2n+4.8[/tex]
B. The y intercept.
To get the y intercept, we set n to 0
i.e
[tex]f(0) =0.2 * 0+4.8[/tex]
[tex]f(0) =0+4.8[/tex]
[tex]f(0) =4.8[/tex]
Hence, the y intercept is 4.8

Triangle ABC has vertices A(-3,0) B(0,6) C(4,6). Find the equations of the three perpendicular bisectors of the same triangle.
Answer:
1.[tex]y=-6x+6, y=\frac{6}{5} x+\frac{18}{5}, y=\frac{6}{11} x+\frac{42}{11}[/tex]
2.[tex]y=-\frac{1}{2} x+2\frac{1}{4} , x=2, y=-\frac{7}{6}x+\frac{43}{12}[/tex]
Step-by-step explanation:
A(−3, 0), B(0, 6), and C(4, 6)
using the midpoint formula: [tex](\frac{x_1+x_2}{2}, \frac{y_1+y_2}{2})[/tex] we can find all of their midpoint which is necessary to complete question 1 and 2
Mid AB=(-1.5, 3), Mid BC=(2, 6), Mid AC=(0.5,3)
Next, we have to find the slope of from the vertex and the midpoint of each side. We use the slope formula: [tex]\frac{y_2-y_1}{x_2-x_1}[/tex].
You would get -6, 6/5, and 6/11.
Next you substitute in the coordinates for the equation of each for example: y=-6x, you switch in the set of cords AB which is (-1.5, 3). 3=-6(-1.5)+z and find that z=6, so the equation is y=-6x+6. As for the rest, repeat the same process until you find all 3 cords. You should get an answer of [tex]y=-6x+6, y=\frac{6}{5} x+\frac{18}{5}, y=\frac{6}{11} x+\frac{42}{11}[/tex]
For question 2,
The line has to be perpendicular bisector to the midpoint, signifying that it has to split 2 angles into congruent angles and a side into half. In order to do that we need to first find the opposite reciprocal of each side's slope. Which means we need to once again use the slope formula and get the opposite reciprocal by [tex]-\frac{1}{slope}[/tex]. For all the opposite reciprocal slopes you get will be incorporated into the final formulas. That gives us the slopes of -1/2, 0 and -7/6. Then do the same process of matching cords with these incomplete equations and you can find the final equations of [tex]y=-\frac{1}{2} x+2\frac{1}{4} , x=2, y=-\frac{7}{6}x+\frac{43}{12}[/tex]
I hope that helped with your question!! :)
