Answer:

3 pizzas

Step-by-step explanation:

34-4=30

30/10=3

Answer:

3 pizzas

Step-by-step explanation:

34-4=30 since we already know the delivery fee

30/10=3 since we have 30 dollars left without the delivery fee we are just left to divide 30 by 10 to get the total number of pizzas

Answer:

Answer: D- point and line

Step-by-step explanation:

Answer:

(- 5, - 3 )

Step-by-step explanation:

Given the 2 equations

- 3x + 10y = - 15 → (1)

5x - 7y = - 4 → (2)

Multiplying (1) by 5 and (2) by 3 and adding the result, eliminates the x- term.

- 15x + 50y = - 75 → (3)

15x - 21y = - 12 → (4)

Add (3) and (4) term by term to eliminate x, that is

29y = - 87 ( divide both sides by 29 )

y = - 3

Substitute y = - 3 into either of the 2 equations and solve for x

Substituting into (1)

- 3x + 10(- 3) = - 15

- 3x - 30 = - 15 ( add 30 to both sides )

- 3x = 15 ( divide both sides by - 3 )

x = - 5

solution is (- 5, - 3 )

Step-by-step explanation:

X^2 = 9^2 - 3^2

x^2 = 81 - 9

x^2 = 72

x = √72

x = 8.485

Answer:

meema, papa, and then auntie jo

Step-by-step explanation:

you need to find the slope of each of them and then determine which one is the fastest and which one is the slowest.

meema: 48-24/4-2 = 4/2 = 2

papa: 40-24/5-3 = 16/2 = 8

auntie jo: 45-18/5-2 = 27/3 = 9

Answer:

A 5:3

Step-by-step explanation:

Answer: 124.8cups of whipped cream

Step-by-step explanation:

for every 5 cups of blueberries there are 312 cups of whipped cream so you will multiply 312 and 2

(312×2= 624)

Then divide it by 5

(624÷5= 124.8)

Answer: D

Step-by-step explanation:

Answer:2n + 3

Step-by-step explanation:

The provided expression is equivalent to the first expression in the option, choice (A) is correct.

It is defined as the combination of constants and variables with mathematical operators.

The question is incomplete.

The complete question is in the picture, please refer to the attached picture.

We have expressions:

[tex]\rm = \dfrac{2n}{n+4}+\dfrac{7}{n-1}[/tex]

[tex]\rm =\dfrac{2n\left(n-1\right)}{\left(n+4\right)\left(n-1\right)}+\dfrac{7\left(n+4\right)}{\left(n+4\right)\left(n-1\right)}[/tex]

[tex]\rm =\dfrac{2n^2+5n+28}{\left(n+4\right)\left(n-1\right)}[/tex]

Thus, the provided expression is equivalent to the first expression in the option, choice (A) is correct.

#SPJ2

Answer:

(a,b) to (-a,-b)

Step-by-step explanation:

You can think of this as folding the paper horizontly and vertically, and see where the new point lies. You see that the x coordinate changes its sign  when the paper folds vertically, and the y coordinate changes its sign when folded horizontally.

But in general, if you have point (a,b) and if you rotate it 180 degrees, you just switch the signs, and you will get (-a,-b).

Ex. (-6,5) rotates 180 degrees and becomes (6,-5)

Answer:

(6,-5)

Answer:

72 dogs

Step-by-step explanation:

3 dogs/2 cats = x dogs/48 cats

Cross Multiply

3/2 x x/48

2x=144

x=72

Answer:

72 dogs

Step-by-step explanation:

First turn 3:2 into a fraction:

3/2

Then you can make the equation a proportion question, which is much eaiser to handle.

3/2=x/48  (I recommend writing this out so it will be easier to see)

Then you cross multiply, or multiply by the numerator of the first fraction by the denominator of the second, and the denominator of the first fraction by the numerator of the second.

Multiply 2 by x, which becomes 2x.

Multiply 3 by 48, which is 144

This becomes... 2x=144

You then solve with equation by dividing 144/2 and getting 72.

Meaning x=72 dogs

Answer:

The answer is below

Step-by-step explanation:

Which equation in slope-intercept form represents a line that passes through the point (2,3) and is perpendicular to the line y−9=23(x+7)

Solution:

The equation of a line in slope intercept form is given as y = mx + b, where m is the slope and b is the y intercept.

Given a line y−9=23(x+7)

y - 9 = 23x + 161

y = 23x  + 170. The slope of this line comparing with y = mx + b gives m = 23

Two lines are perpendicular if the product of their slope gives -1.

Let [tex]m_1[/tex] be the slope of the perpendicular line, hence:

[tex]m_1(23)=-1\\\\m_1=\frac{-1}{23}[/tex]

Since the perpendicular line passes through (2, 3), we can get its equation using:

[tex]y-y_1=m_1(x_x_1)\\\\y-3=\frac{-1}{23}(x-2)\\\\y= \frac{-1}{23}x+\frac{2}{23}+3\\\\ y= \frac{-1}{23}x+\frac{71}{23}[/tex]

Answer:

The solution of this system of linear equations is [tex](x,y) = (-3,-2)[/tex].

Step-by-step explanation:

Let be the following system of linear equations:

[tex]2\cdot x - 7\cdot y = 8[/tex] (1)

[tex]-3\cdot x + 2\cdot y = 5[/tex] (2)

From (1) we clear [tex]y[/tex]:

[tex]2\cdot x -8 = 7\cdot y[/tex]

[tex]y = \frac{2\cdot x - 8}{7}[/tex]

And we apply this variable in (2):

[tex]-3\cdot x+2\cdot \left(\frac{2\cdot x -8}{7} \right)= 5[/tex]

[tex]-3\cdot x +\frac{4}{7} \cdot x -\frac{16}{7} = 5[/tex]

[tex]-\frac{17}{7}\cdot x = \frac{51}{7}[/tex]

[tex]x = -\frac{51}{17}[/tex]

[tex]x = -3[/tex]

And the value of [tex]y[/tex] is:

[tex]y = \frac{2\cdot (-3)-8}{7}[/tex]

[tex]y = -\frac{14}{7}[/tex]

[tex]y = -2[/tex]

The solution of this system of linear equations is [tex](x,y) = (-3,-2)[/tex].
