Answer:

B, C, D, E

Step-by-step explanation:

To graph the equations (sorry i dont have a camera), use the up/down line and on the 6 put a dot, then move one space to the right, and four squares down to place your next dot. This is for y = -4x+6. To graph y = 4x - 2, go back to the up/down line, to the -2 part, and put a dot. then go to the right once, and up four times to place your next dot. when the lines connect, you should be able to find your point, at (1, 2)

Answer:

Option D: [tex]12\frac{1}{2}[/tex] is the correct answer.

Step-by-step explanation:

Given that:

3/4 inches on map are equal to [tex]7\frac{1}{2}[/tex] miles

We will find the unit rate in term of inches.

[tex]\frac{3}{4}\ inches = 7\frac{1}{2}\\\\Unit\ rate = \frac{15}{2}*\frac{4}{3}\ miles\\\\Unit\ rate = 10\ miles\ per\ inch[/tex]

Total distance covered by Bonnie according to map;

Total distance = [tex]\frac{1}{2}+\frac{3}{4} = \frac{2+3}{4}[/tex]

Total distance = [tex]\frac{5}{4}\ miles[/tex]

Actual distance = [tex]\frac{5}{4}*10 = \frac{25}{2}\ miles \\[/tex]

Actual distance = [tex]12\frac{1}{2}\ miles[/tex]

Hence,

Option D: [tex]12\frac{1}{2}[/tex] is the correct answer.

Answer:

x = 11

Step-by-step explanation:

Here, we want to get the value of x

Let’s start by looking at the point U

Now, we can see angles on a straight line at that point

Mathematically, angles on a straight line are supplementary

What this mean is that they add up to 180

Now, the value of the angle that falls into the triangle on that straight line will be;

180-(11x + 12)

Now, we have all the angles of the triangle

Mathematically, the sum of all is 180 as the a sum of the angles of a triangle is 180

5x + 10 + 58 + 180-(11x+2 )= 180

5x + 10 + 58 -11x-2 = 0

-6x+ 66 = 0

6x = 66

x = 66/6

x = 11

Answer:

The total number of cookies is 90

Step-by-step explanation:

As, they said 40% of the total number of cookies is 36, we will take the total as "x"

= 40% of x = 36

40/100 X x = 36

40x = 36 x 100

40x = 3600

x = 3600/40

x = 90

So total cookies she baked = 90

Let's check!

So 40% of 90 need to be 36

So,

40/100 x 90 = 3600/100

= 36

So therefore, total number of cookies = 90

Answer:

2/3

Step-by-step explanation:

5/6*4/5=20/30

20/30 divided by ten equals 2/3

the answer is 2/3

Answer:

The water amount will be equal at 19.5 minutes

Step-by-step explanation:

Here, we want to find the value of t when the water level in both tanks will be equal

We simply proceed to equate both ;

That will be;

30t + 25 = -20t + 1000

30t + 20t = 1000-25

50t = 975

t = 975/50

t = 19.5 minutes

9514 1404 393

Answer:

  $6.87

Step-by-step explanation:

The cost of 0.6 pounds of blueberries is ...

  (0.6 lb)($3.98/lb) = $2.39

The cost of 1.8 pounds of clementines is ...

  (1.8 lb)($2.49/lb) = $4.48

Then the total cost of the purchase is ...

  $2.39 +$4.48 = $6.87

The combined cost is $6.87.

Answer:

Step-by-step explanation:

For number 1.

If x = -2.

                    y = 4x + 3 = 4(-2) + 3 = -8 + 3 = -5

If x = 3

                    y = 4x + 3 = 4(3) + 3 = 12 + 3 = 15

If x = -4

                   y = 4x + 3 = 4(-4) + 3 = -16 + 3 = -13

If x = -5

                  y = 4x + 3 = 4(-5) + 3 = -20 + 3 = -17

If x = 5

                  y = 4(x) + 3 = 4(5) + 3 = 20 + 3 = 23

For number 2.

If x = -2

                 [tex]y = x^{2} + 4 + 2x = (-2)^{2} + 4 + 2(-2) = 4 + 4 - 4 = 4[/tex]

If x = 3

                [tex]y = x^{2} + 4 + 2x = (3)^{2} + 4 + 2(3) = 9 + 4 + 6 = 19[/tex]

If x = -3

                [tex]y = x^{2} + 4 + 2x = (-3)^{2} + 4 + 2(-3) = 9 + 4 - 6 = 7[/tex]

If x = 4

               [tex]y = x^{2} + 4 + 2x = (4)^{2} + 4 + 2(4) = 16 + 4 + 8 = 28[/tex]

If x = -4

               [tex]y = x^{2} + 4 + 2x = (-4)^{2} + 4 + 2(-4) = 16 + 4 -8 = 12[/tex]

Perpendicular bisector means it divides the line into two equal part at 90°

Answer:

The answer should be 14/15.

Step-by-step explanation:

The answer is 14/15 because -2/5 and 4/3 with a common denominator turns into -6/15 and 20/15.

Then you add both of them together.

-6/15 + 20/15 = 14/15

Answer:

7x + 2

Step-by-step explanation:

Original Equation: 3x − ( −2 − 4x)

First, we distribute the negative sign:

= 3x + (−1) (−2−4x)

=3x + (−1)(−2) + (−1)(−4x)

= 3x + 2 + 4x

Using the communitive property of addition, we can write:

= 3x + 4x + 2  (Instead of 3x + 2 + 4x)

Combining like terms, we get:

= (3x + 4x) + 2

= 7x + 2

That's the final Answer, and don't worry about the answer in point form. I worked it out correctly. All steps followed;

Answer:

[tex]Total = 20v + 40x + 80y[/tex]

[tex]Total = 20(v + 2x + 4y)[/tex]

Step-by-step explanation:

The options were not given,en but the question can still be solved.

Given

[tex]Daises = \$ x[/tex]

[tex]Magnolias = \$ y[/tex]

[tex]Vase = \$ v[/tex]

Required

Determine the cost of 20 vases, 40 daises and 80 magnolias

If 1 vase costs $v, then

[tex]20\ vases = 20 * v[/tex]

[tex]20\ vases = 20v[/tex]

If 1 daises costs $x, then

[tex]40\ daises = 40 * x[/tex]

[tex]40\ daises = 40x[/tex]

If 1 magnolias costs $y, then

[tex]80\ magnolias = 80 * y[/tex]

[tex]80\ magnolias = 80y[/tex]

[tex]Total = 20v + 40x + 80y[/tex]

Another expression that represents the total is to factorize the expression.

[tex]Total = 20(v + 2x + 4y)[/tex]

Answer:

(x-y)/z

Step-by-step explanation:

Answer: Option A.

Step-by-step explanation:

Simplifying

xy + -9z = 4

Solving

xy + -9z = 4

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '9z' to each side of the equation.

xy + -9z + 9z = 4 + 9z

Combine like terms: -9z + 9z = 0

xy + 0 = 4 + 9z

xy = 4 + 9z

Divide each side by 'y'.

x = 4y-1 + 9y-1z

Simplifying

x = 4y-1 + 9y-1z

Step-by-step explanation:

[tex]\sf \frac{3}{a} x - 4 = 20\\\\Add \ 4 \ to \ both \ sides\\\\\frac{3}{a} x = 20+4\\\\\frac{3}{a} x = 24\\\\Multiply \ both \ sides \ by \ a\\\\3x = 24 * a\\\\Divide \ 3 \ to \ both \ sides\\\\x = 24a / 3\\\\x = 8a\\\\\rule[225]{225}{2}[/tex]
