Answer:

y = 3x + 3

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

calculate m using the slope formula

m = $\frac{y_{2}-y_{1} }{x_{2}-x_{1} }$

with (x₁, y₁ ) = (- 1, 0) and (x₂, y₂ ) = (0, 3) ← 2 points on the line

m = $\frac{3-0}{0-(-1)}$ = $\frac{3}{0+1}$ = $\frac{3}{1}$ = 3

the line crosses the y- axis at (0, 3 ) ⇒ c = 3

y = 3x + 3 ← equation of line

I need to find the surface area for this one pls help me

Alex

Step-by-step explanation:

so, you got the volume but don't know how to find the surface area ? that is strange for me. what's the problem ?

the surface of a cube or rectangular prism consists of 6 sides that split (for a rectangular prism) into 3 pairs of equal sides :

top and bottom

left and right

front and back

all we need to do is calculate the areas of these 6 rectangles and add them up. that's it.

in our case

top and bottom : 5×4 × 2 = 20×2 = 40 in²

left and right : 4×4 × 2 = 16×2 = 32 in²

front and back : 5×4 × 2 = 40 in²

so, in total, the whole surface area of the prism is

40 + 32 + 40 = 112 in²

Please help with math

Answer:

Scale factor = 3

Step-by-step explanation:

Using similar triangles

AT/AG = AB/AC

9/3 = x+10/3x-10

Cross multiply

3(x+10) = 9(3x-10)

Expand

3x+30 = 27x-90

3x-27x = -90 - 30

-24x = -120

x = 120/24

x = 5

For the larger triangle;

AC = 3x-10

AC = 3(5)-10

AC =15-10

AC = 5

AB = x+10

AB = 5+10

AB = 15

For the scale factor;

Since AT/AG = AB/AC

9/15 = 3/5

3*3/5*3 =3/5

Since the numerator and denominator of the larger triangle is multiplies by the same factor i.3 3. Hence the scale factor is 3

Hi can you help me please?)

<em>*To solve for a specified variable, you need to isolate that variable onto one side.</em>

Firstly, subtract 5r on both sides: $2p=q-5r$

Lastly, divide both sides by 2 and <u>your answer will be $p=\frac{1}{2}q-\frac{5}{2}r$ </u>

First, subtract z on both sides of the equation: $-10-z=xy$

Next, divide both sides by y and <u>your answer will be $\frac{-10-z}{y}=x$ </u>

Firstly, multiply both sides by b: $a=cb$

Next, divide both sides by c and <u>your answer will be $\frac{a}{c}=b$ </u>
