Step-by-step explanation:

b/c we can substructure 5cd and 3dc b/c it doesn't matter if the place of cd and dc change. what I mean if 5 ×3=15 and it is the same with 3×5=15 both of the product are the same but, if it is - and ÷ it wil be wrong for example 5-3=2 but 3-5= -2

Write the slope intercept form of the graph plz

Answers

Answer:

y = 3x - 6

Step-by-step explanation:

slope intercept form is: y = mx + b

m is your slope, so figure it out by doing rise/run

you rise 3, over one which is 3/1, but simplifies to 3

b is your y-intercept, find it by seeing where the line crosses the y-axis, which is -6

therefore, your answer is: y = 3x - 6

The cost of a daily rental car is as follows: The initial fee is $69.99 for the car, and it costs $0.30 per mile. If John initially pays $200.00 before taxes and does not want to exceed that amount, how many miles can he drive?

x ≥ 433 miles
x = 450 miles
x ≥ 450 miles
x ≤ 433 miles

Answers

x [tex]\geq[/tex] 433

explanation:

let m equal miles

0.30m + 69.99 = 200

           -69.99     -69.99

0.30m = 130. 01

130.01 / 0.30 = 433. 36...

but we're gonna round it to 433

so 433 miles

3x-9=7x+14 solve for x

Answers

Answer:

x= - 23/4

Step-by-step explanation:

Add  9  to both sides of the equation:

3x -9 = 7x +14

3x- 9 + 9 = 7x +14 +9

Simplify:

3x -9 + 9 = 7x +14 +9

3x = 7x +14 +9

3x =7x +14 +9

Subtract 7x from both sides of the equation:

3x= 7x +23

3x -7x = 7x +23 - 7x

Simplify Again:

3x -7x = 7x +23 -7x

-4x =23

Combine like terms:

-4x =23

Divide both sides of the equation by the same terms:

14x/ 14  = 23/ -4

Cancel terms that are both the numerator and the denominator:

x= - 23/- 4

Answer:

x= - 23/4

у+ 4 = -4(х+2) what is this in standard form?​

Answers

Answer:

4x + y = -12

Step-by-step explanation:

Standard form is Ax + By = C

First, distribute the -4:

у + 4 = -4(х + 2)

y + 4 = -4x - 8

Subtract 4 from both sides:

y = -4x - 12

Add 4x to both sides:

4x + y = -12

So, the standard form equation is 4x + y = -12

Answer:

<ABC = 51°

Step-by-step explanation:

Given

<A = 2x -15°

<B = x - 5°

< C = 148°

Now

<A + <B = < C ( Exterior angle of a triangle is equal to the sum of two opposite interior angles)

2x -15° + x - 5° = 148°

3x - 20° = 148°

3x = 148° +20°

3x = 168°

x = 168° / 3

X = 56°

Now for Angle B

= 56° - 5°

= 51°
