Write an equation in slope-intercept form for each table below. Show how you found the slope and y-intercept.
Answer:
y = 2x + 1
Step-by-step explanation:
The intercept is the point where the line touches the y axis. The slope is determined by calculating the rise divided by run.
Which system of equations could you use to
determine where the paths intersect?

9. Write the equation of the line in slope-intercept form given the following:
Point (0, 1), (2, -1)
Answer:
y=1x+1
Step-by-step explanation:
We already know the Y intercept is 1 from the first set of points given
The change in x is 2 and the change in Y is also 2 so when you make the slope equation y/x you get 1
Pluggin in the numbers you get: y=1x+1

The sail and mast of a sailboat form a right triangle.What is the height of the mast on the sailboat? height 20m width 12m
Answer: 16 m
Step-by-step explanation:
Using the Pythagorean theorem you can find the height of the mast.
The formula is;
a² + b² = c²
a is one side of the triangle such as the width
b is another side such as the height
c is the hypotenuse which is the longest side.
c will therefore be 20m.
a will be 12m
12² + b² = 20²
b² = 400 - 144
b² = 256
b = √256
b = 16m

Step-by-step explanation:
1) 3/4x = 1/2 2) 2x = 3/11 3) 1 1/2 x = 12 4) 1/5x = 1/6
x = 1/2 * 4/3 x = 3/11 * 1/2 3/2x = 12 x = 1/6 *5/1
x = 2/3 x = 3/22 x = 12 * 2/3 x = 5/6
x = 4*2
x= 8

Step-by-step explanation:
Angle 43 and x are called same-side exterior anglesThat means they sum up to 180 degrees, so[tex]43^{\circ}+x^{\circ}=180^{\circ}\\43^{\circ}-(43^{\circ})+x^{\circ}=180^{\circ}-(43^{\circ})\\x^{\circ}=137^{\circ}[/tex]2). Arielle has a collection of grasshoppers and crickets. She has 561 insects in all.
The number of grasshoppers is twice the number of crickets. Find the number of
each type of insect that she has
Arielle has 374 grasshoppers and 187 crickets in all.
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
Let's set
x = number of grasshoppers
y = number of crickets
Arielle has a collection of 561 insects, therefore
x + y = 561 [1]
The number of grasshoppers is twice the number of crickets, so
x = 2y [2]
Substituting [2] in [1]:
2y + y = 561
Simplifying
3y = 561
Dividing by 3
y = 561/3
y = 187
From [2]:
x = 374
x = 374
Hence, the number of each type of insect that she has 374 grasshoppers and 187 crickets

Sarah has a brother who is 5 years younger than herself and another brother who is 8 years younger than herself. She observes that the product of her brothers ages is equal to the age of her 40 year old father. How old is Sarah? How do we setup an equation for this using null factor law presumably.
Answer:
Sarah is 13 years old
Step-by-step explanation:
Represent Sarah's age with S
Her first brother's age with F
Her second brother's age with B
So, we have:
From the first statement, we have:
[tex]S - F = 5[/tex] ---- (1)
From the second, we have:
[tex]S - B = 8[/tex] ---- (2)
The product of their ages is 40.
First, we make F the subject in (1) and B the subject in (2)
[tex]F = S - 5[/tex]
[tex]B = S - 8[/tex]
Their product is represented as follows:
[tex]F * B = 40[/tex]
Substitute values for F and B
[tex](S - 5) * (S - 8)=40[/tex]
Open bracket
[tex]S^2 - 5S -8S + 40 = 40[/tex]
[tex]S^2 - 13S + 40 = 40[/tex]
Subtract 40 from both sides
[tex]S^2 - 13S = 0[/tex]
Factorize:
[tex]S(S - 13) = 0[/tex]
Split:
[tex]S = 0[/tex] or [tex]S - 13 = 0[/tex]
But Sarah's age can't be 0 because she has two younger brothers.
So, we stick to
[tex]S - 13 = 0[/tex]
Make S the subject
[tex]S = 13[/tex]
Hence, Sarah is 13 years old
Given that these two triangles are similar, what is the measure of L???
Answer:
35°
Step-by-step explanation:
Each triangle has a total degree of 180° so you know that one triangle has degrees of 90°&55° then you can subtract that from 180 to find out. But since they are similar they have to have the same angles and the first triangle tells you the missing angle.

Answer:
357°FStep-by-step explanation:
Step one:
given data
actual reading= 350°F
thermometer reading 2% of the actual reading
Step two:
Required:
The thermometer reading
let us find 2% of 350°F
2/100*350°
=0.02*350
=7°F
Hence the thermometer reading is 7°F greater than 350°F
The thermometer reading is 350+7=357°F
Match each graph with the correct slope of the line. drag and drop the answer
Answer/Step-by-step explanation:
✔️Slope of the first graph:
Using two points on the line, (0, 1) and (3, 2),
[tex] slope (m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{2 - 1}{3 - 0} = \frac{1}{3} [/tex]
Slope = ⅓
✔️Slope of the second graph:
Using two points on the line, (0, 0) and (1, 1),
[tex] slope (m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{1 - 0}{1 - 0} = \frac{1}{1} = 1 [/tex]
Slope = 1
✔️Slope of the third graph:
Using two points on the line, (0, 1) and (2, 2),
[tex] slope (m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{2 - 1}{2 - 0} = \frac{1}{2} [/tex]
Slope = ½
The correct slopes of the graphs are as follows:
1. m = 1 / 3
2. m = 1
3. m = 1 / 2
slope = m = y₂ - y₁ / x₂ - x₁
1.
(0, 1)(6, 3)
m = 3 - 1 / 6 - 0 = 2 / 6 = 1 / 3
2.
(0, 0)(3, 3)
m = 3 - 0 / 3 - 0 = 3 / 3 = 1
3.
(0, 1)(4, 3)
m = 3 - 1 / 4 - 0 = 2 / 4 = 1 /2

Gavin has 50 tokens and continues to ride the roller coaster three times every hour Gibson has 12 tokens and finds two more tokens on the ground every hour how long until they have the same amount of tokens?
Answer:62
Step-by-step explanation: I just did it and got it right
They have the same amount of tokens after t = 7.6 hours.
What is the unitary method?The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.
Since Gavin initially has 50 token and rides the roller coaster three times per hour, he uses 3 token per hour.
So, a number of token he losses after t hours is 3 token per hour × t hours = 3t.
Thus, the number of tokens left after t hours is T = 50 - 3t
Since Gibson initially has 12 tokens and find two tokens on the ground per hour, he gains 2 tokens per hour.
So, number of token he gains after t hours is 2 token per hour × t hours = 2t.
Thus, the number of tokens he has after t hours is T' = 12 + 2t
To find the time t when they will have the same tokens, T must be equal to T', that is T = T'.
So, 50 - 3t = 12 + 2t
Now collecting like terms, we have
50 - 12 = 3t + 2t
38 = 5t
Then dividing both sides by 5, we have
t = 38/5
t = 7.6 hours
Hence, they have the same amount of tokens after t = 7.6 hours.
