Solve for f 7a - 3d + 6f = 5

Answer:  x=-5  x=2

Step-by-step explanation:

x^2+5x-2x-10=0  factor out x from the expression

Xx(x+5)-2x-10=0   factor out x+5 from the expression

(x+5)x(x-2)=0 when the product of factors equals 0, at least one factor is 0

x+5=0   solve for the equation x

x-2=0

       x=-5

      x=2

Answer: A is the 8-pack, B is the single roll, C is the 100 pack, D is the 50 pack.

Step-by-step explanation:

For each of these, multiply the smaller number by a number that has a product of the bigger number, example D. multiply 25 by 2 to get 50, then compare the totals.

Answer:

the first one is an 8 pack of glue sticks

the second one is 1 tape roll for .19

the third one is 100 pack of pencils for 4.88

the fourth one is a 25 pack of paper clips

Given problem;

  Write the equation of the line with the given slope and y-intercept

 The equation of a line is expressed as;

          y  = mx + b;

   m is the slope and b is the y-intercept

7. m = -5, b = -6

   y  = mx + b

Input the parameters:

    y = -5x -6

8. m = 1, b = -4

   y = mx + b

Input the parameters:

   y = x - 4

9. m = 0.4, b = -9

    y = mx + b

Input the parameters:

    y = 0.4x - 9

10. m = 0, b = 3

     y = mx + b

Input the parameters:

    y = 3

Answer:

So using process of elimination it isnt possible for it to be AA or not similiar bc they are similiar since there vertical angles so were left with picking between SSS and SAS which I know that there is an angle that is congruent which is at the midpoint so if i were you I would put SAS similarity.

I just took a test of this lesson so I hope im right.

Answer:

45

Step-by-step explanation:

To find you need to turn the percent into a decimal and multiply it by the number you want to find the percent of.

0.15 x 300=45

Ratio of children, adults and pensioners is 1 : 2 : 8/3 = 3 : 6 : 8.

Let, 3x is number of children.

So, 6x is number of adults and 8x is number of pensioners.

Now,

3x + 6x + 8x = 85

17x = 85

x = 5

Therefore, number of pensioners are 8×5 = 40.

Hence, this is the required solution.

Answer:

-7

Step-by-step explanation:

-7-5=-12

-12×2=-24

-7+1=-6

-6×4=-24

-24=-24

Answer:

x = -7

Step-by-step explanation:

2(x - 5) = 4(x + 1)

Multiply the parenthesis by the outside numbers (simplify).

2x - 10 = 4x + 4

Combine like terms (add 20 to both sides, and subtract 2x).

0 = 2x + 14

Subtract 14 from both sides of the equation.

2x = - 14

Divide both sides of the equation by 2.

x = -7

Hope this helps, let me know if you have any questions :)

Answer: D) y ≤ 5/2x + 5

The slope is 5/2 and the y-intercept is 5. The area shaded should be to the right of the line because it is less than or equal to.

Hope this helps!

Answer:

x = -15/2 or -7.5

Step-by-step explanation:

6x - 4(x - 9) = 2(3 - x)

6x - 4x + 36 = 6 - 2x

2x + 36 = 6 - 2x

4x + 36 = 6

4x = -30

x = -30/4

x = -15/2

Check:

6(-7.5) + -4(-7.5 - 9) = 2(3 + 7.5)

-45 + 66 = 2(10.5)

21 = 21

Answer:

[tex]-\frac{15}{2}[/tex]

Step-by-step explanation:

6x-4(x-9)=2(3-x)

6x-4x+36=6-2x (expansion)

2x+36=6-2x (collecting like terms)

2x+2x=6-36

4x=-30 (-30/4)

x=-[tex]-\frac{15}{2}[/tex]

Answer:

19.1

Step-by-step explanation:

Answer:

b. 2x - y = 5

you are able to change the equation to y = 2x -5. this is then in the form of y = mx + b.

m = slope and b = y-intercept

m = 2 and b = -5

Answer

d. x - 2y = 10

Step-by-step explanation:

The answer you chose does have the correct y intercept, but the incorrect slope, it was asking for a slope of 1/2, not a slope of -2.

REMEMBER: The y intercept is when x = 0, the x intercept is when y = 0.

To find the y intercept, substitute 0 for x, and solve for y. The slope is the coefficient of x when the coefficient of y is 1.

Just convert this standard form equation into slope intercept.

Standard Form: Ax + By = C.

Slope Intercept: y = mx + b. (m is the slope, b is the y intercept)

To convert just get y by itself completely on the left side of the equation. (y has to have a coefficient of positive 1)

x - 2y = 10

-x -x

-2y = -x + 10

÷2 ÷2 ÷2

-y = -1/2x + 5

×-1 ×-1 ×-1

y = 1/2x - 5 → y = mx + b

m = 1/2, and b = -5

Answer:

The volume will be four times the original volume.

Step-by-step explanation:

V = (pi)r2h is the formula for the volume of a cylinder. The formula becomes V = (pi)(2r)2h if the radius is doubled and the height remains the same. V = 4(pi)r2h after simplifying. ... Therefore the new volume would be 4 times the original volume.

Answer:

x+(x+7)=91

Step-by-step explanation:

Hope this helps :)

Answer:   your answer for the smaller number is 38.5 and the larger number is 52.5.

Step-by-step explanation:

To make sure it's right, I just add the numbers together.

Your Problem:

91 ÷ 2 = 45.5

45.5 + 7 = 52.5

45.5 - 7 = 38.5

52.5 + 38.5 = 91
