#3 Solve for the letter A

Answer:

2x2−6x−4

Step-by-step explanation:

Let's simplify step-by-step.

5x^2+2x−11−(3x^2+8x−7)

Distribute the Negative Sign:

=5x^2+2x−11+−1(3x^2+8x−7)

=5x^2+2x+−11+−1(3x^2)+−1(8x)+(−1)(−7)

=5x^2+2x+−11+−3x^2+−8x+7

Combine Like Terms:

=5x^2+2x+−11+−3x^2+−8x+7

=(5x^2+−3x^2)+(2x+−8x)+(−11+7)

=2x^2+−6x+−4

Answer is 4

-y=-4x+8

y=4x-8

Answer:

4/1 or just 4

Step-by-step explanation:

4x - y = 8

subtract 4x from either side

-y = 8 - 4x

divided either side by -1

y = 8 + 4x

M= 4

Complete question:

Kyle incorrectly says that the product of - ( - 6 ) # ( - 1 ) is 6 . 11. After a recycling awareness program, the number of tons of recyclable material taken to the landfill is reduced by 13 7/10 tons per month. Represent the total change in the tons of recyclable material taken to the landfill after 7 months resulting from the awareness program a. What is the correct product? 10 month. Represent the total change in the b. What was Kyle's likely error?

Answer:

Kindly check explanation

Step-by-step explanation:

Given that :

Kyle incorrectly says that the product of - ( - 6 ) ( - 1 ) is 6

-(-6)(-1) = 6 [incorrect]

Correction:

-(-6) (-1) :

- (-6) = 6

6 (-1) = - 6

Given that reduction in materials = 13 7/10 tons per month

Monthly reduction = 13 7/10 = 137/10 tons

After 7 months : (7 * 137/10) = 959/10 tons = 95.9 tons

Change in amount of material taken to the land fill:

Initial amount - amount after 7 months

If initial amount = x

Change in amonnt = (x - 95.9) tons

Answer:

5x-3(x-2)=10+x

Step-by-step explanation:

the is anserw is x=4

Answer:

5x^2 - 12x - 4 = 0

Step-by-step explanation:

5x - 3 (x - 2) = 10 + x

(5x - 3) (x - 2) = 10 + x

(5x^2 - 10x - 3x +6) = 10 + x

5x^2 - 13x + 6 = 10 + x

5x^2 - 13x +6 - 10 - x = 0

5x^2 - 12x - 4 = 0

3×(d±4)≡32

3d±12≡32

    -12   -12

3d≡20

20÷3≡6 2/3

Answer:

Area = 1/2 bh

Area = 18

Base = 9

height = ?

18 = 1/2 x 9 x h

cross multiply

18 x 2 = 1 x 9 x h

36 = 9h

divide both sides by 9

h = 4

(a) The formula for area of a triangle is expressed in terms of h as [tex]h = \frac{2A}{b}[/tex]

(b) The height, h of the triangle is calculated as 4 in

Given:

area of a triangle, [tex]A= \frac{1}{2} bh[/tex]

To find:

(a) The formula, (area of a triangle) is expressed in terms of h as;

[tex]A = \frac{1}{2} bh\\\\multiply \ both \ sides \ of \ the \ equation \ by\ 2\\\\bh = 2A\\\\divide \ through \ by \ b\\\\\frac{bh}{b} = \frac{2A}{b} \\\\h = \frac{2A}{b}[/tex]

(b) The height, h of the triangle is calculated as

[tex]h = \frac{2A}{b}\\\\Recall , A = 18 \ in^2 , \ b = 9\ in\\\\h = \frac{2\times 18}{9}\\\\h = 4 \ in[/tex]

Step-by-step explanation:

2(x + 2) = 2x + 4

2x + 4 = 2x + 4

Both sides are identical so we can replace x with any value we like and the equation will balance, so there are infinitely many solutions.

Answer:

D

Step-by-step explanation:

Count the number of places it takes to get one place past  3

There are 5 zeros in the given question. That gets you to just before the 3.

Add one more to get past the 3. That makes 5 zeros + 1 more place = 6

Since you are moving right, the 6 is minus. Your answer is 3 * 10^-6

Answer:

Slope Intercept Form: y = [tex]\frac{1}{4}[/tex] x + 1

Point Slope Form: y - 2 = [tex]\frac{1}{4}[/tex] × (x - 4)

Standard Form: 1x - 4y = -4

Step-by-step explanation:

Answer:

[tex]y=\frac{1}{4} x+1[/tex]

Step-by-step explanation:

A linear equation needs two pieces of information: the slope of the line, and its y-intercept. Since we are already given the slope we can plug that into the standard equation format:

y=mx+c, where m=slope and c=y-intercept

y=1/4x+c

Now we just need to find the y-intercept.

To find it we are given a point: (4,2), which we can use to trace back to the y-intercept using the slope. The slope of the line of 1/4. This means that the point before it is located 4 units to the left on the x intercept, and 1 unit lower on the y-intercept. Conveniently, this gives us our y-intercept, as the x values 4-4=0. The y value is 1 (2-1) so our y-intercept is 1!

So now we have our equation:

y=1/4x+1

Answer:

D. 6 1/12

Step-by-step explanation:

First add the like fractions.

3 2/3 + 2/3 = 3 4/3 (Don't worry about simplifying yet)

Now find the least common multiple for 3 4/3 and 1 3/4 so we can add them.

3: 3, 6,  9, 12

4: 4, 8, 12

In this case 12 is the least common multiple.

3/4 x 3/3 = 9/12    9/12

4/3 x 4/4 = 16/12

Add those two fractions then add the whole numbers and put it in front.

4 25/12

Simplify
