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

2x = 19

/2     /2

x = 9.5

Answer:

[tex] y = \frac{1}{2}x + \frac{1}{4} [/tex]

Step-by-step explanation:

Equation in slope-intercept form is given as [tex] y = mx + b [/tex]

An equation parallel to [tex] y = \frac{1}{2}x + \frac{5}{2} [/tex] would have the same slope as the equation.

The slope (m) of the line would be ½.

m = ½.

Given that this same line runs through or contains (³/2, 1), we cam find the value of b (y-intercept) by substituting m = ½, x = ³/2, and y = 1 in [tex] y = mx + b [/tex].

Thus:

[tex] 1 = (\frac{1}{2})(\frac{3}{2}) + b [/tex]

[tex] 1 = \frac{3}{4} + b [/tex]

Subtract both sides by ¾

[tex] 1 - \frac{3}{4} = b [/tex]

[tex] \frac{1}{4} = b [/tex]

To derive the equation, substitute m = ½, and b = ¼ in [tex] y = mx + b [/tex].

✔️The equation is:

[tex] y = \frac{1}{2}x + \frac{1}{4} [/tex]

There are a lot of questions here. I'll do problems 7 and 8 to get you started.

====================================================

Problem 7

The given equations are

y = x^2 + 5x - 2

y = 3x - 2

Since both right hand sides are equal to y, we can equate them, get everything to one side, and solve

x^2 + 5x - 2 = 3x - 2

x^2 + 5x - 2 - 3x + 2 = 0

x^2 + 2x = 0

x(x + 2) = 0

x = 0 or x + 2 = 0 ........ zero product property

x = 0 or x = -2

Now plug each x value back into one of the original equations given

If x = 0, then

y = 3x-2

y = 3*0-2

y = -2

Making (0,-2) as one solution. Repeat for the x value x = -2

y = 3x-2

y = 3(-2)-2

y = -8

The point (-2, -8) is the other solution to the system.

-------------------------------

Answer: There are two solutions and they are (0, -2) and (-2, -8)

====================================================

Problem 8

y = -x^2 - 3x + 2

y = x + 6

We'll use the same idea as before

y = -x^2 - 3x + 2

x + 6 = -x^2 - 3x + 2

x + 6 + x^2 + 3x - 2 = 0

x^2 + 4x + 4 = 0

Now factor the left side to solve for x

(x+2)(x+2) = 0

(x+2)^2 = 0

x+2 = 0

x = -2

Use this x value to find y

y = x+6

y = -2+6

y = 4

Or we can cay

y = -x^2 - 3x + 2

y = -(-2)^2 - 3(-2) + 2

y = 4

We get the same y value either way.

-------------------------------

Answer: There is one solution and it is (-2, 4)

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

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

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)

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.

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]

Option A is correct option.
