Answer:

x=-58/15

Step-by-step explanation:

distribute first 10-2.5x+12=21-10x-28

Simplify(add the numbers) 22-2.5x=-7-10x

move the variable to the left side 22-2.5x+10x=-7

move the constant to the right side -2.5x+10x=-7-22

simplify like terms 7.5x=-29

divide by 7.5                       x=-58/15

alternate forms are x=-3 13/15                or  x=-3.86

Answer:

y = m x + b      standard form for straight line

m = (y2 - y1) / (x2 - x1)

When y2 = 12,  x = -6

when y = 0, x = -2

m = (12 - 0) / (-6 - (-2)) = -3

so y = -3 x + b

Also, when x = 0, y = -6

Our equation is

y = -3 x - 6

As a check try x = -2

y = (-3 * -2) +  (-6) = 0     as the graph shows

Assuming you meant to type h(x)=-4x+1

Answer:

[tex]f(x)=-\frac{1}{4}x+\frac{1}{4}[/tex]

Step-by-step explanation:

We know that, because [tex]h(x)[/tex] is the inverse of [tex]f(x)[/tex], that [tex]h(f(x))=x[/tex], so [tex]-4f(x)+1=x[/tex].

Aha! We can solve for [tex]f(x)[/tex]!

We subtract [tex]1[/tex] from both sides to get [tex]-4f(x)=x-1[/tex].

Finally, we divide both sides by [tex]-4[/tex] to get [tex]\boxed{f(x)=-\frac{1}{4}x+\frac{1}{4}}[/tex].

Answer:

] The three consecutive even numbers are 38, 40 and 42. The smallest of the three is clearly 38.           Step-by-step explanation:Even numbers are of the form [math]2k[/math], [math] k \in \mathbb{Z}[/math]. Three consecutive even numbers are of the form [math]2k[/math], [math]2(k+1)[/math], [math]2(k+2)[/math]. We have that their sum is 120 therefore [math]\\2k + 2(k+1) + 2(k+2) = 120 \Leftrightarrow k+(k+1)+(k+2) = 60 \Leftrightarrow 3(k+1) = 60 \\ \Leftrightarrow k+1=20 \Leftrightarrow \boxed{k=19}.[/math

Answer: 3/4

Step-by-step explanation:

9/14 divided by 6/7 is 3/4

Find the reciprocal of the divisor

Reciprocal of 6/7: 7/6

Now, multiply it with the dividend

So, 9/14 divided by 6/7 = 9/14 x 7/6

= 9 x 7 = 63

= 14 x 6 = 84

After reducing the fraction, the answer is 3/4

Hope this helps :)

The division of the fraction 6/7 by 9/15 gives the result 4/3.

To simplify the division of 6/7 divided by 9/14, multiply the first fraction by the reciprocal of the second fraction.

The reciprocal of a fraction is obtained by swapping the numerator and the denominator.

So, the reciprocal of 9/14 is 14/9.

Now, rewrite the division as multiplication:

(6/7) * (14/9)

To multiply fractions, multiply the numerators together and the denominators together:

= (6 * 14) / (7 * 9)

= 84/63

Now, divide the numerator and denominator by their greatest common divisor, which is 21:

= (84/21) / (63/21)

= 4/3

Therefore, 6/7 divided by 9/14 simplifies to 4/3.

7. Translation

Step-by-step explanation:

6: To solve for π means to isolate it on one side.

Step 1: Divide both sides by 2r.

Therefore, π = circumference over twice the radius, or circumference over diameter.

7: #7 is a translation because each point is moving vertically 3 units and horizontally 1 unit (3 units up and 1 unit to the right). If it were a reflection, we'd be able to spot a line of reflection, but there isn't any here. Also, if it were a rotation, the triangle would change the way its angled, and it'd be in a different quadrant

Therefore, this is a translation.
