Answer:

y=-2x+2

Step-by-step explanation:

Slope intercept form:

y=mx+b

Find slope:

4-2/-1-0

Slope = 2/-1

slope = -2

Plug-in known values

4=-2(-1)+b

4=2+b

b=2

You can also plug in the other ordered pairs.

2=-2(0)+b

2=b

b=2

Answer:

x = 4 and y = -1

Step-by-step explanation:

Given that,

6x+5y=19  ... (1)

2x+3y=5 ...(2)

We need to solve the above equations.

Multiply equation (2) by 3.

6x+9y=15 ...(3)

Subtract equation (1) and (3).

6x+5y-(6x+9y)=19-15

6x+5y-6x-9y = 4

-4y = 4

y = -1

Put the value of y in equation (2).

2x+3(-1)=5

2x-3=5

2x=8

x=4

So, the solution of the above equations are x = 4 and y = -1.

Answer:

y = -1

Answer:

v = 3.75 mph

Step-by-step explanation:

Constant speed motion

An object travels at a constant speed if the ratio of the distance traveled by the time taken is constant.

Expressed in a simple equation, we have:

[tex]\displaystyle v=\frac{d}{t}[/tex]

Where  

v = Speed of the object

d = Distance traveled

t = Time taken to travel d.

Sam walks from home to school for a distance of d=0.75 miles in t=12 minutes. To calculate the speed, we need to convert the time to hours.

t=12/60 = 0.2 hours. Now compute the speed:

[tex]\displaystyle v=\frac{0.75\ mi}{0.2 \ h}[/tex]

v = 3.75 mph

Answer:

Number of hot dogs sold =  56

Number of  hamburgers sold = 52

Step-by-step explanation:

Let

Number of hot dogs sold = x

Number of  hamburgers sold = y

We can make equation from given equations:

[tex]0.50x+1y=80[/tex] (Hot dogs were sold for $.50 (fifty cents), and hamburgers were sold for $1 (one dollar). The total money raised by your class was $80. )

[tex]x+y=108[/tex]  (Together you sold 108 hot dogs and hamburgers.)

Now we cam solve these system of equations to find value of x and y

[tex]0.50x+y=80--eq(1)\\x+y=108--eq(2)[/tex]

Subtract both equations to get value of x:

[tex]0.50x+y=80\\x\:\:\:\:\:\:\:\: + y=108\\-\:\:\:\:\:\:\:\: -\:\:\:\:\:\: -\\---------\\-0.5x=-28\\x=\frac{-28}{-0.5}\\x=56[/tex]

We get value of x = 56

Now putting value of x in equation 2 to find value of y

[tex]x+y=108\\56+y=108\\y=108-56\\y=52[/tex]

So, we get y = 52

Therefore,

Number of hot dogs sold = x = 56

Number of  hamburgers sold = y = 52

x greater that -4 and less or equal to -1

The integer solutions to the given inequality is {-3, -2, -1, 0, 1}.

Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.

The given inequality is 2x<3x +4 ≤ x+6.

2x<3x +4

Subtract 2x on both the sides of inequality, we get

0<x+4

Subtract 4 on both the sides of inequality, we get

-4<x

Now, 3x +4 ≤ x +6

Subtract x on both the sides of inequality, we get

2x+4≤ 6

Subtract 4 on both the sides of inequality, we get

2x≤ 2

Divide 2 on both the sides of inequality, we get

x≤1

Now, -4<x≤1

So, solution is {-3, -2, -1, 0, 1}

Therefore, the integer solutions to the given inequality is {-3, -2, -1, 0, 1}.

Step-by-step explanation:

We can find the modulus/absolute value from the point -8.95 to each of the other points:

|(-9) - (-8.95)| = 0.05.

|(-8) - (-8.95)| = 0.95.

|(-7) - (-8.95)| = 1.95.

So what this tell us is that the point -8.95 is furthest away from -7 and is closest to -9. It is also much closer to -9 than to -8. (compare 0.05 with 0.95)

Hence the best answer is Point A. (A)

cicumference of circle =2Πr=2×3.14×4.2=26.3

The circumference of the circle will be 26.4 cm.

The circumference, which is the distance around the object, the diameter, which is the length of a circle measured from one end to the other and passing through its center, and the radius, which is equal to half of the diameter, are the three key characteristics.

Given, A circle has a radius of 4.2 cm.

From the general formula of the circumference of the circle:

Circumference of the circle = 2*pi* radius

in our case,

Circumference of the circle = 2*pi *4.2

Circumference of the circle = 26.389 cm

Therefore, The circumference of the circle will be 26.4 cm.

Answer:500(1.2)^t> 850

Step-by-step explanation:

got it right on the test

The missing values in the expression are t > log(850/A)/logb if Resource managers need to determine the number of years.

It is defined as the expression in mathematics in which both sides are not equal they have mathematical signs either less than or greater than known as inequality.

We have:

Resource managers need to determine the number of years after which purple loosestrife will cover more than 850 acres of the wetland.

c = 850

[tex]\rm A(b)^t > 850[/tex]

[tex]\rm (b)^t > \dfrac{850}{A}[/tex]

Taking log and solving for t:

t > log(850/A)/logb

Thus, the missing values in the expression are t > log(850/A)/logb if Resource managers need to determine the number of years.

Answer:

The area is 23.49 cm²

Step-by-step explanation:

Let us solve the question

In the given triangle

∵ The base of the triangle has a length of 8.7 cm

∴ The base = 8.7 cm

∵ The height of this base has a length of 5.4 cm

∴ The height = 5.4 cm

∵ The area of the triangle = [tex]\frac{1}{2}[/tex] × base × height

→ Substitute the values of the base and the height

∴ The area of the triangle = [tex]\frac{1}{2}[/tex] × 8.7 × 5.4

∴ The area of the triangle = 23.49 cm²

∴ The area is 23.49 cm²
