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 calculated value   t = 0.452< 2.2621 at 0.05 level of significance

null hypothesis is accepted

Based on the sample, can it be concluded that μ is not different from 45 centimeters

Step-by-step explanation:

Step( i ):-

Heights were measured for a random sample of 10 plants

Size of the sample 'n' = 10

Mean of the sample (x⁻ ) = 46 centimeters

Standard deviation of the sample (s) = 7 centimeters

Mean of the Population ( μ ) = 45

Step(ii):-

Null Hypothesis :H₀:( μ ) = 45

Alternative Hypothesis : H₁:  μ ) ≠ 45

Test statistic

             [tex]t = \frac{x^{-}-mean }{\frac{S}{\sqrt{n} } }[/tex]

            [tex]t = \frac{46-45}{\frac{7}{\sqrt{10} } }[/tex]

           t = 0.452

  Degrees of freedom

                 γ = n-1 = 10 -1 = 9

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

Answer:

The value of cos Ф is ± [tex]\frac{1}{2}[/tex]

Step-by-step explanation:

There are important rules for sin Ф and cos Ф

∵ sin Ф = [tex]\frac{\sqrt{3}}{2}[/tex]

∴ sin²Ф = [tex](\frac{\sqrt{3}}{2})^{2}[/tex]

∴ sin²Ф = [tex]\frac{3}{4}[/tex]

→ By using the third rule above

∵ cos²Ф = 1 - sin²Ф

∴ cos²Ф = 1 - [tex]\frac{3}{4}[/tex]

∴ cos²Ф = [tex]\frac{1}{4}[/tex]

→ Take square root for both sides

∴ cos Ф = ± [tex]\frac{1}{2}[/tex]

∴ The value of cos Ф is ± [tex]\frac{1}{2}[/tex]

Answer:

B. 1

Step-by-step explanation:

The quotient will have 1 decimal place because one of the numbers in the calculation has one decimal place, and the answer is only allowed to be as exact as the numbers used in the equation.

To make sure the answer is correct, we can do the math:

170.8/14 = 12.2

12.2 only has one decimal place, so answer choice B is correct.

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!! :)

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)
