Evaluate the function f(x) = -7x + 2 at f(-18).

Step-by-step explanation:

we are to first collect like terms here I mean all numbers that look alike are to be out on the same side so we are now going to have.

[tex]2 - 8x > 34[/tex]

[tex] - 8x > 34 - 2[/tex]

[tex] - 8x > 32[/tex]

now we are to divide both sides with the coefficient of x and we are to get

[tex] - 8x \div - 8 < 32 \div - 8 = x < 4[/tex]

Answer:

1/4

Step-by-step explanation:

It's not entirely clear to me what you're trying to solve, but it looks like the initial equation is

[tex]\dfrac{a-2}{a+3} -1 = \dfrac3{a+2}[/tex]

First convert each term into a fraction with the same (i.e. the least common) denominator. The first term needs to be multiplied by a + 2; the second term by (a + 3) (a + 2); and the third term by a + 3 :

[tex]\dfrac{a-2}{a+3}\cdot\dfrac{a+2}{a+2} -1\cdot\dfrac{(a+3)(a+2)}{(a+3)(a+2)} = \dfrac3{a+2}\cdot\dfrac{a+3}{a+3} \\\\ \dfrac{(a-2)(a+2)}{(a+3)(a+2)} - \dfrac{(a+3)(a+2)}{(a+3)(a+2)} = \dfrac{3(a+3)}{(a+3)(a+2)}[/tex]

Now that everything has the same denominator, we can combine the fractions into one. Move every term to one side and join the numerators:

[tex]\dfrac{(a-2)(a+2)-(a+3)(a+2)-3(a+3)}{(a+3)(a+2)} = 0[/tex]

Simplify the numerator:

[tex]\dfrac{(a^2-4)-(a^2+5a+6)-(3a+9)}{(a+3)(a+2)} = 0 \\\\ \dfrac{-8a-19}{(a+3)(a+2)} = 0[/tex]

If neither a = -3 nor a = -2, we can ignore the denominator:

[tex]-8a-19 = 0[/tex]

Solve for a :

[tex]-8a = 19 \\\\ \boxed{a = -\dfrac{19}8}[/tex]

Answer:

The first box is 4, the second box which is above the third box is 12 and the third box is 8

Step-by-step explanation:

To add fractions, you have to find like terms. So, you have to make 1/2 have a denominator of 8.

8/2 is 4, so 1/2 equals 4/8.

Now, the first box above the 8 will be 4.

The second and third boxes will be the sum to 4/8+8/8 which is 12/8.

Answer:

x=4

Step-by-step explanation:

117+59=176

176+4=180

x=4

Answer:

x = 20

Step-by-step explanation:

I just plugged in the x possibilities until they both matched, and because they are on opposite sides, as in if they were in the same grid they would be right across from each other, they represent the same angle.

You could also set them equal to each other.

As in:

3x + 32 = 5x - 8

This would simplify (after isolating x) to:

40 = 2x

Divide by 2

20 = x

[tex]\boxed{ \rm{answer \: by \: { \boxed{ \rm{☆HayabusaBrainly}}}}}[/tex]

3x + 32° + 5x - 8° = 180°

8x + 24° = 180°

8x = 180° - 24°

8x = 156°

x = 156 ÷ 8

At 2:25, the distance between the tip of the hour hand and the minute will be greater.

The distance between the hour hand and the minute hand is measured in degrees and the higher the degree, the greater is the distance between the tip of the hour hand and the tip of the minute hand.

From an hour to another;

So, starting from 12 toward the clockwise direction, the tip of the hour shift twice; i.e.

= 2 × 30°

= 60°

Now, in 2hr : 20 minutes, the distance is:

[tex]\mathbf{= 60+(\dfrac{20}{60})\times 30^0}[/tex]

= 70°

In 2hr : 25 minutes, the distance is:

[tex]\mathbf{= 60+(\dfrac{25}{60})\times 30^0}[/tex]

= 72.5°

Thus, at 2:25, the distance between the tip of the hour hand and the minute will be greater.

Answer:

11a−29b−50

Step-by-step explanation:

Hope this helps brodie

The simplified expression for ‐3 + 7(a – 3b – 1) – 4(10 – a + 2b) is 11a - 29b - 50.

To simplify the expression -3 + 7(a - 3b - 1) - 4(10 - a + 2b), we can apply the distributive property and combine like terms:

-3 + 7(a - 3b - 1) - 4(10 - a + 2b)

= -3 + 7a - 21b - 7 - 40 + 4a - 8b

= (7a + 4a) + (-21b - 8b) + (-3 - 7 - 40)

= 11a - 29b - 50

Therefore, the simplified expression is 11a - 29b - 50.

-12,0

Step-by-step explanation:

i took the quiz

Answer:

The x intercept is -12

Step-by-step explanation:

Because we need to find the x intercept (x,0)

We can substitute y or F(x) into 0

0=x+12

Subtract 12 on both sides

x=-12

so (-12,0) or -12
