Answer: B.16

Step-by-step explanation:

using pythagoras

[tex]20^{2} = x^{2} + 12^{2}[/tex]

400 = [tex]x^{2}[/tex] + 144

[tex]x^{2}[/tex] = 256

x = 16 and -16

please give me a brainliest answer.

Answer:

x = [tex]\frac{16+b-4a}{4}[/tex]

Step-by-step explanation:

4(a + x) - b = 16 ( add b to both sides )

4(a + x) = 16 + b ← distribute parenthesis on left side

4a + 4x = 16 + b ( subtract 4a from both sides )

4x = 16 + b - 4a ( divide both sides by 4 )

x = [tex]\frac{16+b-4a}{4}[/tex]

Answer:

y = ½x - 4

Step-by-step explanation:

Given the linear equation in point-slope form, y + 2 = ½(x - 4):

To transform the equation into its slope-intercept form, y = mx + b:

y + 2 = ½(x - 4)

Distribute ½ into the parenthesis:

y + 2 = ½x - 2

Subtract 2 from both sides:

y + 2 - 2 = ½x - 2 - 2

y = ½x - 4 ← This is the slope-intercept form.

Answer:

A. The rate of change of this graph is 3

B. The rate of change represent 3 Souvenirs are purchased in one day of vacation.

Step-by-step explanation:

A. By looking at the graph the x axis is changing by 1, and the y axis is chaning by 3 so the rate of change is 3.

B. The rate of change is 3 means 3souvenirs are purchases in 1 day of vacation.

Answer:

4

Step-by-step explanation:

( x1, y1 ) = ( 5, 3 )

Here,

x1 = 5

y1 = 3

( x2, y2 ) = ( 6, 7 )

Here,

x2 = 6

y2 = 7

Formula : -

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

Slope = ( 7 - 3 ) / ( 6 - 5 )

= 4 / 1

Slope = 4

Answer:

(y−3)=4(x−5)

Step-by-step explanation:

Point slope form is defined by the formula [tex]y-y_{1}=m(x-x_{1})[/tex]

First, you find the slope using the slope equation [tex]\frac{y_{2} -y_{1}}{x_{2}-x_{1}}[/tex]. (7−3)/(6−5)=4. Then you plug it back into the point slope form equation, and also plug in the points from y1 and x1.

This is also y=4x−17 in slope-intercept form or −4x+1y=−17 in standard form.

Answer:

A. This conclusion was drawn using the law of detachment

Step-by-step explanation:

Definition:

Law of Detachment

If p equals q and p is also true. Then q is true.

if a number is a whole number, then it is an integer.

3 is a whole number (true statement) , so it 3 is an integer. (must be true)

Answer:

Suzanne's lessons are 20 minutes long.

Jim's lessons are 50 minutes long.

Step-by-step explanation:

Jim's lessons = 30min longer than Suzanne's lessons

Suzanne's lessons = 1/3 of Pedro's lessons

Pedro's lessons = 60min

First, you need to find Suzanne's lesson time because her lessons are linked to Pedro's. Since you know Pedro's lesson is 60 minutes long and Suzanne's are a third of that you do: 60/3. Which is 20. So you know Suzanne's lessons are 20minutes long.

Next, since you know Suzanne's lessons are 20minutes long and Jims are 30mins longer than Suzanne's you do: 20+30. Which equals 50minutes. So, Jim's lessons are 50minutes long.

428 - 1,212 = -784

? = -784

hope it helps!

Answer:

- 784

Step-by-step explanation:

428 - x = 1,212​

1,212 - 428 = - x

- x = 784

x = - 784

Answer:

x = -5

Step-by-step explanation:

x = -5 because a horizontal line does not change in y value

Horizontal line that goes through the point V(-5,17) is y=17.

The horizontal line that passing through any point (a,b) is y=b

So the horizontal line passing through the point is y=17

= 21/4 x -2/5. flipped and multiplied

= -21/10

= -2 1/10

Answer:

-2 1/10

Step-by-step explanation:

5 1/4 = 21/4

-2 1/2 = -5/2

21/4 ÷ -5/2=-21/10 = -2 1/10

Step-by-step explanation:

just think about the basic formulas for area and perimeter of rectangles, and what pieces of information we already have directly.

area = length × width

perimeter = 2×length + 2×width = 136 m

=> length + width = 68 m

then we know

length = 2×width + 8

this we use as substitute in the simplified perimeter equation :

2×width + 8 + width = 68

3×width + 8 = 68

3×width = 60

width = 20 m

and therefore

length = 2×width + 8 = 2×20 + 8 = 40+8 = 48 m

and now we can calculate the area :

area = length×width = 48×20 = 960 m²

please consider that for a length or distance we use m (or other length units), for and area then m². for a volume then m³. as a basic unit for an area is a square. and for a volume a cube.
