Answer:

D

Step-by-step explanation:

f(-9) = 3/5(-9) + 8 = 13/5

Option C, a = (w - 4b )/7 is the correct answer

w = 7a + 4b

7a = w - 4b

a = (w- 4b )/7

Answer: x = 0, y = 0

Step-by-step explanation:

x + y = 27y = 8x

Consider the first equation. Subtract 27y from both sides.

x + y = -27y = 0

Combine y and -27y to get -26y

x - 26x = 0

Consider the second equation. Subtract 8x from both sides.

27y - 8x = 0

To solve a pair of equations using substitution, first solve one of the equations for one of the variables. Then substitute the result for the variable in the other equation.

x - 26y = 0, -8x + 27y = 0

Choose one of the equations and solve it for x by isolating x on the left hand side of the equal sign.

x - 26y = 0

Add 26y to both sides of the equation.

x = 26y

Substitute 26y for x in the order equation,

-8x + 27y = 0.

-8 x 26y + 27y = 0

Multiply -8 times 26y

-208y + 27y = 0

Add -208y to 27y

-181y = 0

Divide both sides by -181.

y = 0

Substitute 0 for y in x = 26y. Because the resulting equation contains only one variable, you can solve for x directly.

x = 0

Answer:

The equation is linear. Standard form:

7n - 6m - 4 =0

Step-by-step explanation:

Linear Equations

The linear equations are identified because all terms form a polynomial of degree 1 or zero (no variable).

The standard form of a linear equation is:

ax+by+cz+d=0

where x, y, z are the variables, and a,b,c are constants.

The equation:

7n - 8m = 4 - 2m

Is linear, both variables have an exponent of 1 and there is an independent term. Moving all terms to the left side:

7n - 8m - 4 + 2m =0

Simplifying:

7n - 6m - 4 =0

Answer:

Step-by-step explanation:

The idea hear is to find the least common multiples of 15 and 24

Given that they separated at exactly 1:00pm

the multiples are

15= 15,30,45,60,75,90,105,120

24= 24, 48,72,96,120

the multiples common is 120

Therefore they will meet in 120minute, which is 2 hours time \

hence the time will be 3:00pm

Answer:

B. y=3/4x+6

Step-by-step explanation:

tttttttttttttt

Answer: B

Step-by-step explanation: the y-intercept is always the b in the equation y=mx+b. in this case it’s 6. Then you look at the rise and the run. its 3/4 because you go up 3 units, and to the right 4 units, to get to the next coordinate point.

Answer:

y=1/2x+0.5

Step-by-step explanation:

The slope is 1/2, which you can see by looking at the change of y/x. The y intercept is 0.5, which can be seen on the y axis.

Answer:

-1/3

Step-by-step explanation:

its rise over run.

u rise 2, and run 6 and its a negative slope

when you simplify its then -1/3

Answer:

[tex]m = -\frac{1}{3}[/tex]

Step-by-step explanation:

Using the slope formula:

            y2 – y1

m   =   --------------

            x2 – x1

Plug in any two points that the line passes through:

In this case, (2, 0) and (–1, 1).

              1 – 0

m   =   --------------

            –1 – 2

                 1

m   =   --------------

Answer:

Step-by-step explanation:

last year won 57 games

this year won 15 games

the difference is 57 - 15 = 42,

this means it drops 42 / 57 = 0.73 (100%)  ≈ 73%

therefore,  the percentage decrease from the given choices is: J

42 =   x  

57     100

The 3 problem

Step-by-step explanation:

Answer:

The answer is C) x+y = 233, 14x + 20y = 3748

Step-by-step explanation:

x(number of t-shirts sold) + y(number of sweatshirts sold) = 233 (total number of pieces of clothing sold)

14x (14 is the cost of each t-shirt and since x = number of t-shirts sold then it is 14x or 14 multiplied by number of t-shirts sold) + 20y (20 is the cost of each sweatshirt and since y = number of sweatshirts sold then it is 20y or 20 multiplied by number of sweatshirts sold) = 3748 (total of money raised)

Answer:

A (-2,-3) B (3,-3)

Step-by-step explanation:

I took math in high school

Answer:

The coordinate numbers are A (-2,-3) B(3,-3)

Question #1

first, you need to find the slope. Use the formula: m=(y₂-y₁)/(X₂-X₁). Plug in x and y values. once you have found the slope, use point-slope form;

(y-y₁)=m(x-x₁). Again, plug in x and y values. Simplify the equation. Do that with the coordinate pairs, to see which one matches y=-1/2x+4. The answer though is A, (-2,5) and (2,3).

Question #2

Do the same thing, find the slope using the formula, and then use point-slope form. After that, find the matching equation and that's the answer. I am confused though because the right equation would be [tex]y=-3x[/tex], but that's not one of the answers.

Answer:

Kali needs 104 more tiles to completely cover the box.

Step-by-step explanation:

Length of box =  20 in

Breadth of box = 6 in

Height of box= 9 in

Total surface area of box = 2lw + 2lh + 2wh

Total surface area of box = 2(20)(6) + 2(20)(9) + 2(6)(9)

Total surface area of box = 708 sq. in.

Side of tile = 1 in

Area of 1 tile = [tex]Side^2 = 1^2 = 1 sq. in[/tex]

Area of 604 tiles = 604 sq. in.

Area remain uncovered = 708 - 604 = 104 sq.in.

So, Kali needs 104 more tiles to completely cover the box.
