Answer:

I'm pretty positive the answer is A. -0.8x+4.8y+16

Step-by-step explanation:

Answer:

Step-by-step explanation:

a)  

4x - 3 = 2x + 7

4x - 2x = 7 + 3

2x = 10

x = 10 / 2

x = 5

b)

2x + 6 = 7x - 14

6 + 14 = 7x - 2x

20 = 5x

x = 20 / 5

x = 4

Step-by-step explanation:

Answer:

0.0576 ft2

Step-by-step explanation:

If the scale factor between a front door's blueprint and the actual front door is 0,04 The front door's actual area is 36 ft2, while its area on the blueprint will be 1.44 ft².

The ratio among comparable dimensions of an object and a model with that object is known as an exponent in algebra. The replica will be larger if the scale factor is a whole number. The duplicate will be lowered if the step size is a fraction.

It is given that, the scale factor of the blueprint of a front door to the actual front door is 0.04. The area of the actual front door is 36 ft².

Scale factor =Area of the new shape ÷ Area of the original shape

0.04= Area of the front door on the blueprint÷36 ft²

Area of the front door on the blueprint=0.04×36

Area of the front door on the blueprint=1.44 ft²

Thus, if the scale factor between a front door's blueprint and the actual front door is 0,04 The front door's actual area is 36 ft2, while its area on the blueprint will be 1.44 ft².

Answer:

y=.1x+3 I think that is the answer

Answer:

y=0.1x+3

Step-by-step explanation:

The slope is 0.1, (Y2-Y1/X2-X1) --> (2.5-3)/(-5-0)= -0.5/-5=0.1

The y-intercept is 3

y=0.1x+3

Answer:

Vertical change= 1

Horizontal change= 2

Rate of change=  1/2

Step-by-step explanation:

The vertical change is how many units you go up on the triangle and the horizontal change is how many units you go left or right on the triangle. The rate of change is the vertical change over the horizontal change. So that is why 1/2 is the rate of change. Have a great day!

Answer:

4

Step-by-step explanation:

Answer:

48 K - 4 L

132 k - 11 L

Step-by-step explanation:

36 ÷ 3 = 12 so that means that for every 1 liter there are 12 Kilomiters.

4 x 12 = 48

11 x 12 = 132

Answer:

4 should be the answer to the question

Answer:

11 1/5 divided by 2 3/4:

11 1/5 is a bit less than 12, and 2 3/4 is a bit less than 3  

The answer, therefore, should be fairly close to 12 ÷ 3

12 ÷ 3 is 4

Answer is 4

2[tex]x^3[/tex] - 7[tex]x^2[/tex] + 8x -3

Step-by-step explanation:

To multiply a binomial (2 terms) by a trinomial (3 terms):

Multiply the first term of the binomial by the each term of the trinomial.

Multiply the second term of the binomial by each term of the trinomial.

Combine the expressions and simplify.

(2x-3)*([tex]x^2[/tex]-2x+1)

(2x * [tex]x^2[/tex]) + (2x * -2x) + (2x * 1)

(2[tex]x^3[/tex]) + (-4[tex]x^2[/tex]) + (2x)

(2x-3) * ([tex]x^2[/tex]-2x+1)

(-3 * [tex]x^2[/tex]) + (-3 * -2x) + (-3 * 1)

(-3[tex]x^2[/tex]) + (6x) + (-3)
