just follow what they say. graph (2,1). rise over run, so up 5 and to the right 3.

Answer:

This is the correct answer the guy above plotted it wrong!

The yellow line is the correct plot!

Answer:

104

Step-by-step explanation:

100%= 1.00

so

420%= 4.20

Multiply 4.20×20

84

now add the original 20

104. She has 104 boxes in total.

Hope this helps! If you have any questions on how I got my answer feel free to ask. Stay safe!

Answer:

104

Step-by-step explanation:

20 + (20*4) + (20*0.2)

= 20 + 80 + 4

= 104

Answer:

[tex]\boxed {\boxed {\sf y= \frac{1}{2}x-5 }}[/tex]

Step-by-step explanation:

Since we are given a point and a slope, we should use the point-slope equation.

[tex]y-y_1=m(x-x_1)[/tex]

where m is the slope and (x₁, y₁) is the point the line passes through.

We are given the slope of 1/2 and the point (4, -3). Therefore:

[tex]m= \frac{1}{2} \\x_1= 4\\y_1= -3[/tex]

Substitute the values into the formula.

[tex]y--3= \frac{1}{2} (x-4)[/tex]

[tex]y+ 3= \frac{1}{2} (x-4)[/tex]

Distribute the 1/2. Multiply each term inside the parentheses by 1/2.

[tex]y+3= \frac{1}{2} *x + \frac{1}{2} * -4[/tex]

[tex]y+3=\frac{1}{2}x-2[/tex]

We want to the equation of the line in slope-intercept form or y=mx+b. We need to isolate y. 3 is being added and the inverse of addition is subtraction. Subtract 3 from both sides of the equation.

[tex]y+3-3=\frac{1}{2}x-2-3[/tex]

[tex]y=\frac{1}{2}x-2-3\\y= \frac{1}{2}x-5[/tex]

The equation of the line is y=1/2x-5

Answer:

The number of cheery pieces in the box are [tex]18[/tex].

Step-by-step explanation:

Let the number of orange pieces in the box be [tex]x[/tex].

The box contains three times as many cherry pieces as orange pieces.

So, the number of cherry pieces in the box be [tex]3x[/tex].

It has four more grape pieces than cherry pieces.

So, the number of grape pieces in the box be [tex]3x+4[/tex].

There are [tex]46[/tex] total pieces in the box.

So, [tex]x+3x+3x+4=46[/tex]

[tex]\Rightarrow 7x+4=46[/tex]

[tex]\Rightarrow 7x=46-4[/tex]

[tex]\Rightarrow 7x=42[/tex]

[tex]\Rightarrow x=\frac{42}{7}[/tex]

[tex]\Rightarrow x=6[/tex]

So, the number of cherry pieces [tex]=3x=3\times 6=18[/tex].

Hence, the number of cheery pieces in the box are [tex]18[/tex].

Answer:

Yes

3

Step-by-step explanation:

a direct variation is written in the form

y = kx

k is a constant which is usually non zero.

6y = k18x

k = 3

An increase in x would lead to an increase in y

Answer:

45°

Step-by-step explanation:

well all the side are equal. Since each angle of this square is 90, and if I'm not mistaken, the two angle are equal to each other.

So both angle x and y are 45°

Answer:

if you multiply the denominator by the AB^3 by 7 you wll get your common factor

Step-by-step explanation:

Step-by-step explanation:

Question 15:

5(x - 9) - 2(x + 3)

= (5)(x) + (5)(-9) - (2)(x) - (2)(3)

= 5x - 45 - 2x - 6

= 3x - 51

= 3(x - 17).

Question 16:

The terms 36x, 18y and 9 have GCF of 9.

Hence 36x - 18y + 9 = 9(4x - 2y + 1).

Answer:

Lisa would travel 417 miles a day.

Step-by-step explanation:

subtract 3,014 - 95 = 2, 919

Then divide 2, 919 / 7 = 417

Answer:

[tex]6[/tex]

Step-by-step explanation:

Recall that [tex]a^{-b}=\frac{1}{a^b}[/tex]. Therefore, any number [tex]n[/tex] raised to the power of [tex]-1[/tex] will be  [tex]\frac{1}{n^1}=\frac{1}{n}[/tex] (the reciprocal of that number).

Thus, the value of the expression [tex]\left (\frac{1}{6}\right)^{-1}[/tex] is:

[tex]\left (\frac{1}{\frac{1}{6}}\right )=\fbox{$6$}[/tex].

Answer:

5x

product means muliply so 5 times x

Answer:

the answer will be 15 number D

Answer:

x = 15 (D)

Step-by-step explanation:

First, we distribute the -1/2:

-1/2 x x = -1/2x

-1/2 x 5 = -2.5

Now we have -1/2x + (-2.5) = -10

Move the variables to one side and the regular numbers on the other (in other words, subtracting both sides by -2.5:

-1/2x = -10 + 2.5

-1/2x = -7.5

x = -7.5/(-1/2)

x = 15   (D)

Answer:

Its an increase

Diameter is twice the radius so divide 24/2 = 12

Then use 12 as radius in the area of a circle equation.

Answer:

£210

Step-by-step explanation:

Given that :

Visa cost = £2300

7% charge of visa price = (0.07 * £2300) = £161

Total cost = £(161 + 2300) = £2461

Amount to be saved per month = £2461 / 12 = £205.08333

= £210 (nearest £10)

Based on the information given the equations that are correct are:

6 thousand 438 divided by 6 equals 1 thousand 73 which is written as 6,438/6=1073 will be calculated using this formula

Numerator/Denominator

Where,

Numerator=6,438

Denominator=6

Let plug in the formula

6,438/6

1 ≤ x ≤ 5

Step-by-step explanation:

Answer:

5[tex]\sqrt[\\]{3} \\[/tex] or about 8.66

Step-by-step explanation:

To find the distance of any line, you have to use distance formula.

[tex]\sqrt{(y-y_{1} )^{2} + (x-x_{1} )^{2}[/tex]

So, we insert our points:

[tex]\sqrt{(5-9 )^{2} + (-3-4 )^{2}[/tex]

Then you solve, and should end up with [tex]\sqrt{75}[/tex]. Either you can simplify it for an exact number, or you can round. It depends on what the directions ask for.
