The equation of a line is y=-3x - 2. What are the slope and the y-intercept of the line?
A. slope = -3 and y-intercept = 2
B. slope = 3 and y-intercept = -2
C. slope = 3 and y-intercept = 2
D. slope = -3 and y-intercept = -2
Answer: D
Step-by-step explanation:
The slope of a linear equation is the m value in the linear equation y=mx+b, in this case m=-3. The y-intercept is the b value in the linear equation y=mx+b, in this case b=-2.
Simplify (1-3i)-(2-i)
Step-by-step explanation:
(1-3i)-(2-i)=
1-2-3i+i=
-1-2i
1-2-3i+i
= -1-2i
Step-by-step explanation:
I simplified it in a simple way by arranging like terms together and did the calculation. Here the like term of 1 is -2 and for -3i it's i. so 1-2= -1 and -3i+i= -2i according to integers rule.

Answer:
y = 9
Step-by-step explanation:
Step 1: Write equation
2(3y - 6) = 42
Step 2: Solve for y
Distribute 2: 6y - 12 = 42Add 12 to both sides: 6y = 54Divide both sides by 6: y = 9The Cost Saver Grocery Club sells sheet cakes. Each 14 sheet of cake requires 0.75 teaspoon of baking soda.

Determine whether the following rates are equal or not using unit rates: 60 units in 3 minutes and 80 units in 4 minutes
Answer:
The rates are equal
Step-by-step explanation:
To see if the rates are equal, divide both of the units by the number of minutes:
60/3
= 20
80/4
= 20
This means both rates are equal, since we got 20 for both of them
This means the rate is 20 units per 1 minute, for both rates.
So, the rates are equal.

Darnell uses 1 1/4 packages of bread to make 10 bracelets. He make 25 bracelets how packages of breads will he use
Answer:
3 1/8 packages of beads
Step-by-step explanation:
We know that Darnell uses 1 1/4 packages of beads to make 10 bracelets. In order to find how many packages of beads he'll need for 25 bracelets, we set up a proportion:
[tex]\frac{1\frac{1}{4} }{10} =\frac{x}{25}[/tex], where x is the number of packages needed
Cross-multiply:
25 * 1 1/4 = 10x
1 1/4 is just 1.25 in decimal form, so:
25 * 1.25 = 10x
31.25 = 10x
x = 3.125 = 3 1/8
So, Darnell will use 3 1/8 packages of beads.
~ an aesthetics lover
Answer:
We can calculate how many packages he needs to make 5 bracelets and then times that by 5 to see how many he'll need for 25
Step-by-step explanation:
First of all, let's turn 1 1/4 to [tex]\frac{5}{4}[/tex]
Now, if we divide the amount he needs for 10 bracelets by 2, we will have the amount he needs for 5 bracelets:
[tex]\frac{\frac{5}{4}}{2} = \frac{5}{4} * \frac{1}{2} = \frac{5}{8}[/tex]
Now, as 25 divided by 5 is 5, we can multiply our answer by 5 to get the amount needed for 25 bracelets:
[tex]\frac{5}{8} * 5 = \frac{25}{8}[/tex]
Now, we can turn this back into a mixed fraction:
[tex]\frac{25}{8} = 3\frac{1}{8}[/tex]
So the answer is 3 1/8 packages of bread.

Choose the equation for the graph
Answer: a) Y= 2|x-3|+1
Step-by-step explanation:
Hope this helps
The equation that describes the graph is the one in option a:
f(x) = 2*|x - 3| + 1
Which equation represents the graph?We can see that the graph is an absolute value equation with a vertex in the point (3, 1), so the absolute value function must be of the form:
f(x) = a*|x - 3| + 1
Now, we also can see that the arms open upwards, so the slope must be positive, and we can see that for each increment in x, we have an increment of 2 units in y, so the slope is a = 2.
This means that the function is:
f(x) = 2*|x - 3| + 1
So the correct option is a.

Emily wants to make a scale drawing of her kitchen. Her kitchen is a rectangle with a length of 6m and a width of 2m. She decides on a scale of 1cm to 0.5m. If the kitchen door is 1.2m wide, how wide should the door be on the scale drawing? Be sure to include units
Answer:
2.4 cm
Step-by-step explanation:
The scaled dimension on the drawing [tex]=[/tex] (Scale-factor) [tex]\times[/tex] (Original dimension)
She decides to draw 1cm for the original length of 0.5m=50 cm.
For this, the scaled dimension on the drawing=1cm and
the original dimention=50 cm
So, the scale-factor = 1/50.
As the kitchen door is 1.2m wide, i.e the original width of the door is 120 cm.
So, the scaled width of the door is
[tex]120\times \frac{1}{50}=2.4 cm.[/tex]
Hence, on the drawing, the width of the kitchen door should be 2.4 cm.

A marching band stands in a triangle formation. The drum major stands at A, one of the vertices of the triangle. The whole formation marches 3 units left and 5 units up. They then march 2 units left and 2 units up. After the movement, what coordinates will the drum major be standing on? A. (11, 3) B. (11, 11) C. (1, 11) D. (1, 3)
Answer:
D. (1, 3)
Step-by-step explanation:
Based on the image uploaded, during the first march, move point A, 3 units left, the new position will (3, -4), then move point A again 5 units up, the new position will be (3,1).
From second march move point A 2 units left, the new position will be (1,1), finally move point A 2units up, the new position and last position will be (1, 3).
Thus, the drum major be standing on (1, 3)

C. m= 6
D. m= 1/6
Answer
B
explanation
get the difference between the y valuesand divide it by the difference between the x values
[tex] \frac{9 - 6}{3 - 5} [/tex]
[tex] \frac{3}{ - 2} [/tex]
The slope of the line passing through the points (5, 6) and (3, 9) is -3/2.
Option B is the correct answer.
We have,
To determine the slope between two points, we can use the formula:
m = (y2 - y1) / (x2 - x1)
Given the points (5, 6) and (3, 9), we can substitute the coordinates into the formula:
m = (9 - 6) / (3 - 5)
m = 3 / (-2)
m = -3/2
Therefore,
The slope of the line passing through the points (5, 6) and (3, 9) is -3/2.
