Solve for a
-1/4a- 4=7/4a- 3

Answer:

-30

Step-by-step explanation:

[tex]\boxed{slope = \frac{y1 - y2}{x1 - x2} }[/tex]

where (x₁, y₁) is the first coordinate and (x₂, y₂) is the second coordinate.

Slope

[tex] = \frac{12 - ( - 18)}{11 - 12} [/tex]

[tex] = \frac{12 + 18}{ - 1} [/tex]

= -30

Answer:

False

Step-by-step explanation:

The point of tangency is the point where a tangent intersects a circle.

Answer:

x > 77

Step-by-step explanation:

According to order of operations rules, we must carry out division before addition or subtraction.  In this case we wish to isolate x and are permitted to simplify the inequality by combining the "like terms" 3 and 8, as follows:

X/7-3>8

     +3 +3

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

x/7 > 11

The easiest way in which to solve for x is to multiply both sides of this inequality by 7:

7(x/7) > 7(11), or

x > 77

All numbers greater than 77 are part of the solution set.

Answer:

If you were to make a 360 degree circle and minus the 50 thats already there you get 310 the right angle on angle 5 is 90 degrees because its a right angle so then the 310-90=220 the obtuse angle on angle 2 is 180 so 220-180=40 lastly you share those forty between angles 3 and 4 and the solution is your answer.

Answer:

  P'(4, 1)

Step-by-step explanation:

Add the translation values to the point coordinates.

  P(4, 5) ⇒ P'(4 +0, 5+(-4)) = P'(4, 1)

Answer:

its 216 cubic feet.

Step-by-step explanation:

6x6x6 is 216

Answer:

(x+7)(x+2) = 66

x^2+9x+14=66

x^2 + 9x -52 = 0

(x+13)(x-4) = 0

x = 4 bc the other root, -13, can't be used (it would make the dimensions negative values)

Answer:

7 9/12

Step-by-step explanation:

1 1/2 + 3/4 + 1 1/2 + 1/2 + 2/3 + 3 =

add together with pairs

3 + 3 1/2 + 1 5/12

add again

6 1/2 + 1 3/12

7 9/12

(I think it's right not 100% percent sure but 95%)

anyways hope this helped :))

Answer: 2.49 s

Step-by-step explanation:

Given

Rock is dropped from a height of [tex]h=100\ ft[/tex]

Using the equation of motion [tex]h=ut+\frac{1}{2}at^2[/tex]

here, [tex]u=0[/tex] (Rock is dropped)

[tex]a=g[/tex]

Putting values

[tex]\Rightarrow 100=0+\dfrac{1}{2}gt^2\\\\\Rightarrow t^2=\dfrac{2h}{g}=\dfrac{2\times 100}{32.2}\\\\\Rightarrow t=\sqrt{6.211}=2.49\ s[/tex]

Answer:

6.5 ft

Step-by-step explanation:

You must use Pythagoras theorem, which is a² + b² = c², then square root c to get answer

if 5.6 = a and 3.3 = b

5.6²+3.3²=42.25(=c²)

42.25 = c²

square root both sides

6.5 = c

Answer:

6.5 ft.

Step-by-step explanation:

To find this you can use the Pythagorean Theorem. [tex]a^2+b^2=c^2[/tex]

[tex]5.6^2 + 3.3^2=C^2[/tex]

31.36+10.89=[tex]C^2[/tex]

42.25=[tex]C^2[/tex]

NOW you have to square root both sides of the equation

[tex]\sqrt{42.25} = \sqrt{C^2}[/tex]

You square root both sides so you can get ride of the exponent on C

So, your answer is 6.5=C

hope this helps :)

p.s. for further questions, [tex]c^2[/tex], is always the opposite side of the right angle.  :)

Answer:

180

Step-by-step explanation:

Answer: 12.75

Step-by-step explanation:

10.25+ .50(5)=12.75

Step-by-step explanation:

Line is passing through the point A (-3, 5) and the point B (0, -16)

a) Slope (m) = (-16 - 5)/(0+3) = - 21/3 = - 7

b) y - intercept (b) = - 16

c) Equation of line

y = mx + b

y = - 7x + (-16)

y = - 7x - 16

Answer:

$25 for Adam and $75 for Hamza

Step-by-step explanation:

$100 will be divided to 3 + 1 = 4 parts

the dollars Adam received

= $100 × 1/4

= $25

the dollars Hamza received

= $100 × 3/4

= $75

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

the dollars Hamza give to Adam

= $75 × 25%

= $75 × 25/100

= $18.75

the dollars Adam have

= $25 + $18.75

= $43.75

the dollars Hamza have

= $75 - $18.75

= $56.25

the ratio

= 43.75：56.25

= 7：9

8 square feet = 2 hours

°divide 2hrs to 8 square feet

1hr = ?

2÷8 =4

so,

1hr = 4 square feet

•4 square feet can be painted in 1 hour.

*now to find how many square can be painted in 7 hrs.

°multiply no. of hours to hd no. of square feet per hour.

7hrs = ?

7×4 =28

So,

may this helps you

Answer:

10

Step-by-step explanation:

First substitute x for 2

3(2) + 4

6+4

10  When x is 2 f = 10

Answer:

1= 180 ft

2 = 60 ft

3= 35 ft

4= 150 ft

Step-by-step explanation:

1 = 3x

2=x

3=x-25

4= 2x+30

425= 7x -5

420=7x

x=60

Answer:

x = -2

Step-by-step explanation:

These 2 angles are alternate exterior so they're equal to each other.

x + 127 = 125

x = 125 - 127

x = -2

Answer:

Below

Step-by-step explanation:

The answer would be 90°

We know that every triangle should add up to 180°,

with that we can solve it!

30° + 40° = 70°!

180° - 70° = 90°!

30° + 40° + 90° = 180°

70° + 90° = 180°
