Answer:

-3x + y = -9

Step-by-step explanation:

Answer:

Ok so we see that at the end there is a +2 so the first thing we want to do is start our first point at (0,2). After that we can see that our slope is -1/2, since slope equals x/y we know that it is asking us to go 1 to the right, however since it is negative we will be going 2 down.  the Y intercept is the point where the line intercepts the Y-axis which is (0,2)

Step-by-step explanation:

Answer:

slope= -1/2

y-intercept = (0,2)

Step-by-step explanation:

The y-intercept is what y equals when x equals zero. On the graph, it is where the graph crosses through the y axis.

To find the y-intercept, plug in 0 for x, so x = 0

y = -1/2 (0) + 2

y=2

and we know x =0

So the point is (0,2)

Answer:

Step-by-step explanation:

57 / 514

=   57 / 514

(Decimal: 0.110895)

Rewrite the equation as  

x /14 =  5/ 7 .  x/ 14 =  5/ 7

Multiply both sides of the equation by  

14.14  ⋅  x /14 =  14 ⋅ 5 /7

Simplify both sides of the equation.

Tap for fewer steps...

Cancel the common factor of  14 .  

Cancel the common factor.

14 ⋅  x /14 =  14 ⋅ 5 /7

Rewrite the expression.

x = 14 ⋅ 5 /7

Simplify  14 ⋅  5/ 7 .

Cancel the common factor of  7 .

Factor  7  out of  14 .

x = 7 ( 2 ) ⋅ 5/ 7

Cancel the common factor.

x = 7 ⋅  2 ⋅  5/ 7

Rewrite the expression.

x  = 2 ⋅ 5

Multiply  2  by  5 .

x = 10

Answer:

Between 9 and 10

Step-by-step explanation:

Area = 95 square feet

The garden is a square

[tex]a^2 = 95[/tex]

a = [tex]\sqrt{95}[/tex] = 9.75

The two whole numbers for side length is between 9 and 10.

The length of this side to the nearest tenth of a foot is 9.8ft.

Answer: 90,75. cos 55°. sin55° ≈ 42,64

through E, draw EK perpendicular to BC (F ∈ BC)

because E is the midpoint of AB => BE = 11/2 = 5.5

ΔBEF is a right triangle at K

=> sin 55° = EK/BE

=> EK = 5,5.sin 55°

ΔABC has E and F is the midpoints of AB and AC

=> EF is  the median line of the triangle

=> EF = 1/2.BC

through A, draw AD perpendicular to BC

=> ΔABD is a right triangle at D

=> BC = 11.cos 55°.2 = 22.cos 55°

=> EF = 11.cos 55°

=>the area of the trapezium BEFC is:

[tex]\frac{5,5.sin55(11.cos55+22.cos55)}{2}=90,75.cos55.sin55[/tex]

Answer:

3x+4

Step-by-step explanation:

Parenthesis are not needed in this equation because it is all addition and subtraction. This means another way to write the equation is:

2x+x+5-1

Combine like terms and the answer you get is:

3x+4

Answer:

Rational

Step-by-step explanation:

We first have to define what these numbers mean:

Real numbers are all the numbers on the number line, they are not imaginary numbers that cannot be quantified on the number line.

Rational numbers are numbers that have either terminating decimals or recurring decimal, for example 5.3 (terminating decimal) or 1.333...(recurring decimal). I did not use the traditional definition of "a/b where a and b are integers and b ≠ 0" because it poses some problems. For instance 22/7 fulfills this condition but it is not a rational number! So it is best defined the way I just defined it.

An irrational number is a number that does not have terminating and recurring decimal, like 3.565215805.....

Integers are real numbers that are whole numbers.

Looking at the situation, which is the money in a bank account. The value will be a number that is rational because it is always an exact amount and this implies that it will always be a terminating decimal. Note that 45.00 is also a terminating decimal.

Answer:

D = 1/2 , E = -1/2 , F = -5/2

Step-by-step explanation:

vertical parabola : ( 1,-2), ( -3, 10 ), (4, 31 )

General form ; [tex]x^2 + y^2 + Dx + Ey + F = 0[/tex]

( 1 ,-2 ) = x1, y1

( -3, 10 ) = x2, y2

( 4, 31 ) = x3, y3

hence :

[tex]y1 = ax_{1} ^2 + bx_{1} + c[/tex]

[tex]y2 = ax_{2} ^2 + bx_{2} + c[/tex]

[tex]y3 = ax_{3} ^2 + bx_{3} + c[/tex]

attached below is the detailed solution required

D = 1/2 , E = -1/2 , F = -5/2

Answer:

-32 I think (plz dont be mad at me if this is wrong)

Step-by-step explanation:

Answer:

f(-2) = 50

Step-by-step explanation:

f(x) = 8x^2 - 14x - 10, find f(-2)

Just like how -2 replaced x in f(x), you will replace x with -2 in the equation

f(-2) = 8(-2)^2 - 14(-2) - 10

f(-2) = 8(4) + 28 - 10

f(-2) = 32 + 18

f(-2) = 50

Answer:

Step-by-step explanation:

The transformations of 1 and 4 are translations (1 and 4) and reflection (4), so are rigid transformations.

The transformation of 3 is a dilation by a factor of 3, so is non-rigid.

The transformation of 2 is a horizontal stretch by a factor of 2 and a vertical stretch by a factor of 3. It, too, is a non-rigid transformation, but is not strictly dilation.

Answer:

$7.75

Step-by-step explanation:

1. Take the cost - $4.80 for the 96 messages, and divide $4.80 by 96 to get the cost per message.

2. 4.80 ÷ 96 = $0.05 per message

3. Take that figure and multiply by 155 messages.

4. 155 × $0.05 per message = $7.75

Hope this helps!

Step-by-step explanation:

Explanation:

Cost of 1 loaf of bread = $4

Cost of 1 roll = $1

The baker needs to sell both items and it should be worth $36.

To find the linear equation, Suppose, the baker sells "b" loaves of bread and "r" rolls.

Then the total cost of the sales has to be $36.

So, the linear equation will be:

4b + 1r = 36

Answer:

4 3/2 is simplified into 5 1/2

Step-by-step explanation:

There are three halves in the improper fraction 3/2. Two of those halves make another whole number, and you are left with one half and 1. 4 + 1 1/2 is equal to 5 1/2.
