Answer:

x = 6

Step-by-step explanation:

Let's solve your equation step-by-step.

6−8x=7x−10x−24

Step 1: Simplify both sides of the equation.

6−8x=7x−10x−24

6+−8x=7x+−10x+−24

−8x+6=(7x+−10x)+(−24)(Combine Like Terms)

−8x+6=−3x+−24

−8x+6=−3x−24

Step 2: Add 3x to both sides.

−8x+6+3x=−3x−24+3x

−5x+6=−24

Step 3: Subtract 6 from both sides.

−5x+6−6=−24−6

−5x=−30

Step 4: Divide both sides by -5.

−5x/-5 = -30 /-5

x=6

Answer:

no solution.

Step-by-step explanation:

2x + 3x + 9 < 5x - 7

5x + 9 < 5x - 7

5x + 9 - 9 < 5x - 7 - 9

5x < 5x - 16

5x - 5x < 5x - 16 - 5x

Step-by-step explanation:

8.43 has two decimal digits. 0.06 has two decimal digits.

The product of eight.43 and 0.06 can have 2*2 = four decimal digits.

843*6 = 5058

8.43*0.06 = 0.5058

Answer:

r1 and r2 are the radii of two concentric circles

To find:

The length of the chord of the larger circle.

Solution:

We have given the two concentric circles which means both the circles have the same centre.

The chord of the larger circle toches the inner circle so the chord of the larger circle will be the tangent of the smaller circle.

And we know that the radius of the circle is perpendicular to the tangent of the circle.

Let 2x be the length of the chord of the circle.

r1 is the radius of the larger circle.

r2 is the radius of the smaller circle.

So by the Pythagoras theorem,

The length of the half of the chord is given by:

r1² = x² + r2²

x² = r1² - r2²

x = √r1² - r2²

So,

The length of the chord will be 2x = 2√r1² - r2² units

Answer:

its b

Step-by-step explanation:

The y-intercept: (0,-5); vertex point: (2,-9); x-intercepts: (-1,0) and (5,0) option (B) is correct.

It is defined as the graph of a quadratic function that has something bowl-shaped.

We have a function:

[tex]\rm f(x) = x^2 - 4x-5[/tex]

The above function shows a parabola equation.

For y-intercept plug x = 0 in the function.

f(0) = -5

So the y-intercept is (0, -5)

For the vertex:

[tex]\rm f(x) = (x-2)^2-9[/tex]  (from perfect square trinomial)

[tex]\rm f(x) = (x-h)^2+k[/tex]

(h, k) is the vertex = (2, -9)

For x-intercept:

f(x) = 0

[tex]\rm x^2 - 4x-5=0[/tex]

After factorizing:

(x+1)(x-5) = 0

So the x-intercept will be:

(-1, 0) and (5, 0)

Thus, the y-intercept: (0,-5); vertex point: (2,-9); x-intercepts: (-1,0) and (5,0) option (B) is correct.

Option B, There is no correlation between the last digit of phone number and the quiz grade.  

Step-by-step explanation:

The values on the scatter plot are dispersed and hence no best fit curve can be drawn for this data set.

Hence there is no relation between the two variables that is last digit of phone number and the quiz grade.  

Answer:

Yeah what he said

Step-by-step explanation:

Answer:

x < -1

Step-by-step explanation:

if he substituded 0 for x into the inequality, he gets 3>4. then he should notice it is incorrect so the riht way to solve is to use subtracting property of inequality and subtract 4 from both sides and get -1 > x

Answer:

the answer would actually be x< -1 then he should've checked his work by replacing the x with -1

Answer:

She has 50 shirts

Step-by-step explanation:

If 8 is 16 percent then 16/100 = 8/50

Answer:

if 8 shirts equal 16%, that means 1 shirt equals 2%, so she has 50 shirts

Step-by-step explanation:

Answer:

Step-by-step explanation:

For parallelogram, the opposite sides are equal. Hence

2x + 4 = 6x - 16

Collect the like terms

2x - 6x = -16 - 4

-8x = -20

x = 20/8

x = 5/2

x = 2.5

Hence the value of x is 2.5

We know that the ratio of wooden bats to metal bats is 2:1. We also know that there are 20 wooden bats.

We need to know how many metal bats there are.

Since 20 of the bats are wooden, that covers the 2. Using common knowledge, we know that this ratio is in the tenths. If the 2 is equal to 20 then the 1 is equal to 10.

There are 10 metal bats.

10 bro- bc 20 divided by 2 is 10 .,. easy math y-y

Step-by-step explanation:

(f + g)(x) = f(x) + g(x)

= (2x² - 9x) + (3x - 2) = 2x² - 6x - 2.

Therefore (f + g)(3) = 2(3)² - 6(3) - 2 = -2.

(f - g)(x) = f(x) - g(x)

= (2x² - 9x) - (3x - 2) = 2x² - 12x + 2.

Therefore (f - g)(-4) = 2(-4)² - 12(-4) + 2 = 82.

(g o f)(x)

= g(2x² - 9x) = 3(2x² - 9x) - 2 = 6x² - 27x -2.

(f o g)(x)

= f(3x - 2) = 2(3x - 2)² - 9(3x - 2) = 18x² - 51x + 26.

Answer:

y = (x – 6) / -3 = [2 – x/3]

Step-by-step explanation:

y = f(x) = -3x + 6

f⁻¹(x) → x = -3y + 6 → (x – 6) / -3 → x / -3 + -6/-3 → -x / 3 + 2 → 2 – x/3

Step-by-step explanation:

AB = 1 unit

A'B' = 3 units

The scale of dilation = A'B'/AB

Therefore:

scale of dilation = 3 units / 1 unit = 3

This means that ABC was dilated or enlarged in size by multiplying every of its segment by 3. In essence, A'B'C' is 3 times the size of ABC.
