Step-by-step explanation:

To find the x-intercept, set y = 0

To find the y-intercept, set x = 0

Answer:

y= -8x-2

Step-by-step explanation:

30-(-42)/-4-5 = slope = 72/-9 simplified to -8

Now that you have the slope, plug in the points

30=-8(-4)+b

30=32-2

B= -2

Answer:

y=3/2x+3

Step-by-step explanation:

The equation is in y=mx+b format. m is the slope, or steepness of the line, while b is the y intercept (where the line crosses with the y axis).

The given line shows the y intercept; it's 3.

To find the slope, use this equation: y2-y1/x2-x1

Pick any two points and plug them into the equation. For example, use (0,3) (y intercept) and (-2, 0) (x intercept.)

now,

3-0/0-(-2)

3/2

the slope is 3/2.

Now, the line is

y=3/2x+3.

Answer:

They started shopping for cloths at 11:45 AM

Step-by-step explanation:

First of all we have to calculate the whole time that they spent in the mall starting from shopping.

They spent 1 hour on shopping, 1 hour and 30 minutes at food court and 30 minutes in video arcade which makes:

[tex]1 + 1.5+ 0.5 = 3\ hours[/tex]

as 30 minutes is equal to half hour so we used 0.5 in place of it.

Now we know that they left at 02:45 PM. We have to see what time it was 3 hours ago.

[tex]02:45\ PM - 03:00 = 11:45\ AM[/tex]

Hence,

They started shopping for cloths at 11:45 AM

Answer:

Step-by-step explanation:

If -3/2 and 5 are solutions to the quadratic equation, hence the expression will give;

(x-(-3/2))(x-5) = 0

(x+3/2)(x-5) = 0

Compare the resulting expression with (ax+b)(x+c)=0, we can see that;

ax = x

divide both sides by x

ax/x = x/x

a = 1

b = 3/2

-5 = +c

c = -5

Hence a = 1,  = 3/2 and c = -5

Answer:

a- 0.05n + 0.25(36 – n) = 6

Step-by-step explanation:

i just did it on edg

The value of each coin (Nickels and Quarters) determines their number in a money sum

The correct option that gives the equation that can be used to solve for the number of nickels, n, is option;

0.05·n + 0.25·(36 - n) = 6

Reason:

The given equation can be presented as follows;

[tex]\begin{array}{|c|c|c|c|}&\mathbf{Number}&\mathbf{Value}&\mathbf{Total \ value}\\&&&\\Nickels&n&0.05&0.05 \cdot n\\Quarters&36 - n&0.25 & 0.25 \cdot(36 - n)\\&&&\\\mathbf{Total}&36&&6\end{array}\right][/tex]

From the above table, we have;

0.05·n + 0.25·(36 - n) = 6

Solving the above equation gives;

0.05·n + 9 - 0.25·n = 6

-0.2·n = 6 - 9 = -3

[tex]n = \dfrac{3}{0.2} = 15[/tex]

Therefore;

The equation that can be used to solve for the number of nickels, n, is; 0.05·n + 0.25·(36 - n) = 6

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

Step-by-step explanation:

add 4 on both sides

leaves you with 15 on the right side

you then divide by negative 2

since you divide by a negative you have to switch the sign

Isolate the variable by dividing each side by factors that don't contain the variable.

The given question is incomplete

Here are some letters and what they represent. All costs are in dollars.

m represents the cost of a main dish.

n represents the number of side dishes.

s represents the cost of a side dish.

t represents the total cost of a meal.

Discuss with a partner: What does each equation mean in this situation? a. a.  m = 7.50

b. m = s + 4.50

c . ns = 6

d. m + ns = t

2. Write a new equation that could be true in this situation.

Answer:

t = 3m -n(s+1)

Step-by-step explanation:

Using the information we can describe the value of each letters

using a and b

        7.50 = s + 4.50

         s = 3

substitute s in c, we get

using equation d we have

so we an equation using the above data

t +ns = 3m - n

t = 3m -n(s+1)

Answer – 7 years old

SOLVINGS

Let Kevin’s present age be ‘x’

In 56 years, Kevin’s age will be x + 56

In 56 years, Kevin’s age will be 9x

Therefore, x + 56 = 9x

Solving for x

x + 56 = 9x

9x – x = 56

8x = 56

x = 56/8

x = 7

Kevin is 7 years old right now.

Answer:

17.5 Km

Step-by-step explanation:

In Monstor zip line, it's 120 km /hour

so in 0.25 hours, it's 0.25 * 120 = 30 Km

in another small

d = 50*h

= 50*0.25

= 12.5 km

so you travel (30-12.5)km farther on the monster zip line = 17.5 Km

Answer:

8x = 32

x = 4

y = 6

Step-by-step explanation:

2.5y + 3x = 27

5x – 2.5y = 5

_____________

8x = 32 (equation obtained after adding the two equations)

x = 32/8

x = 4

Plug x = 4 in 2.5y + 3x = 27

2.5y + 3*4 = 27

2.5y + 12 = 27

2.5y = 27 - 12

2.y5= 15

y = 15/2.5

y = 6

The equation results of adding the two equations is 8x = 32.

The solution to the system is (4, 6).

A straight line on the coordinate plane is represented by a linear function. As an illustration, the equation y = 3x – 2 depicts a linear function because it is a straight line in the coordinate plane.

Any function whose graph is not a straight line is said to be nonlinear. Any curve other than a straight line can be a graph of it.

An example of a non-linear function is a quadratic function.

Given, A system of linear equations in variables 'x' and 'y'.

2.5y + 3x = 27...(i) and 5x - 2.5y = 5...(ii)'

Reaaranging eqn(i) we have

3x + 2.5y = 27...(iii)

Adding (ii) and (ii) we have,

8x = 32.       (As + 2.5y and - 2.5y cancels)

x = 32/8.

x = 4.

Putting the value of 'x' in eqn(i) we have,

2.5y + 12 = 27.

2.5y = 15.

y = 6.

So, The solution to the system is (4, 6).
