Answer:

[tex] m\angle ABC = 35\degree [/tex]

Step-by-step explanation:

(3x - 70)° = x° (corresponding angles)

3x - 70 = x

3x - x = 70

2x = 70

x = 70/2

x = 35

[tex]

m\angle ABC = (3x - 70)\degree \\\\

m\angle ABC = (3\times 35- 70)\degree \\\\

m\angle ABC = (105- 70)\degree \\\\

Write in slope-intercept form an equation of the line that passes through the given points (4, 1), (8, 2)

Answers

Find slope first
(2-1)/(8-4) = 1/4
Format: y = mx + b
y = 1/4x + b
Plug in one point
1 = 1/4(4) + b, b = 0
Solution y = 1/4x

The slope-intercept form of the line is [tex]y=\dfrac{1}{4}x[/tex].

Given:

A line passes through the two points [tex](4,1)[/tex] and [tex](8,2)[/tex].

To find:

The slope-intercept form of the line.

Explanation:

The slope-intercept form of a line is:

[tex]y=mx+b[/tex]

Where, [tex]m[/tex] is slope and [tex]b[/tex] is the y-intercept.

The line passes through the two points [tex](4,1)[/tex] and [tex](8,2)[/tex]. So, the equation of the line is:

[tex]y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)[/tex]

[tex]y-1=\dfrac{2-1}{8-4}(x-4)[/tex]

[tex]y-1=\dfrac{1}{4}(x-4)[/tex]

Using the distributive property, we get

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

[tex]y=\dfrac{1}{4}x-1+1[/tex]

[tex]y=\dfrac{1}{4}x[/tex]

Therefore, the slope-intercept form of the line is [tex]y=\dfrac{1}{4}x[/tex].

Can anyone help with number 9 please

Answers

Answer:

A) 55

Step-by-step explanation:

angle 3 is an exterior angle. to find the interior angle of the triangle, subtract angle 3 from 180

180 - 110 = 70

all the angles in a triangle add up to 180.

since angles 1 and 2 are the same, you can call them x.

70 + 2x = 180

70 - 70 + 2x = 180 - 70

2x = 180 - 70

2x = 110

2x/2 = 110/2

x = 110/2

x = 55

Answer:

A.55

Step-by-step explanation:

The angle that is not numbered =70 because it is the supplementary angles of angle 3. if that is 70 a triangle add to 180 then 180-70=110. and 1 and 2 and equal so 110/2 =55

2. Ashley had a summer lemonade stand where she sold small cups of lemonade for $1.25 and large
cups for $2.50. If Ashley sold a total of 155 cups of lemonade for $265, how many cups of each
type did she sell?

Answers

Answer:

[tex]\boxed {\boxed {\sf 98 \ Small \ Cups}}\\\\\boxed {\boxed {\sf 57 \ Large \ Cups}}[/tex]

Step-by-step explanation:

Let's make a system of equations.

First, define the variables.

Let s= small cups and g= large cups

Next, make 2 equations. 1 for the money and 1 for the number of cups.

Money

A small cup costs 1.25 and a large cup costs 2.50. The total money made is 265. 1.25s+2.50g=265

Number

A total of 155 cups of lemonade were sold. The sum of small cups and large cups sold will equal 155. s+g=155

Here is our system of equations:

[tex]1.25s+2.50g=265 \\s+g=155[/tex]

Now, solve. Let's isolate a variable in the 2nd equation, so we can plug it in after.

Subtract g from both sides of the equation. s+g=155 s+g-g=155-gs=155-g

Now we know that s is equal to 155-g. We can substitute (155-g) in for s in the first equation.

[tex]1.25s +2.50g=265[/tex]

[tex]1.25(155-g)+2.50g=265[/tex]

Distribute the 1.25

1.25(155-g)= (1.25*155)+ (1.25*-g)= 193.75-1.25g

[tex]193.75-1.25g+2.50g=265[/tex]

Work to isolate the variable. Subtract 193.75 from both sides of the equation and combine like terms on the left.

[tex]193.75-1.25g+2.50g=265-193.75[/tex] (Subtract 193.75)

[tex]-1.25g+2.50g=265-193.75[/tex]

[tex]1.25g=71.25[/tex] (Combine like terms).

1.25 and g are being multiplied. The inverse of multiplication is division. Divide both sides by 1.25

[tex]1.25g/1.25=71.25/1.25\\g=71.25/1.25\\g=57[/tex]

Now we know that 57 large cups were sold. Plug 57 back into the original second equation to find the small cups.

[tex]s+g=155[/tex]

[tex]s+57=155[/tex]

Subtract 57 from both sides of the equation to isolate the variable, s.

[tex]s+57-57=155-57\\s=155-57\\s=98[/tex]

Ashley sold 57 large cups and 98 small cups.

small cup she sold = x = 98

large cup she sold = y =57
