Describe the slope of the line.
please help me i will brainliest i swear
Answer:
B
Step-by-step explanation:
In 3y+1, the 3 is the coefficient
Write in slope intercept: slope=2/3 y-intercept =-1
Answer:
y=2/3-1.
Step-by-step explanation:
Slope intercept is the easiest out of the forms because you just plug in what is given. Here you are given 2/3 for the slope and the y-int Is -1.
The formula for slope intercept is y=mx+b
m= slope
b= y-int
And you just plug it in.
so the answer would be: y=2/3-1. Hope this helps!

The double number line shows how far a hummingbird can fly in 1 second -
Complete the table to show the same information as the double number line
Answer:
1
3
130
Step-by-step explanation:
as shown on the lines, it takes the bird one second to fly 13 meters. the answer to the first blank is 1
using this ratio, 13 meters per second, we can find how long it takes for the bird to fly 39 meters.
13/1=39/x
this is 13x=39
x=3 seconds
use the same ratio to find distance
13/1=x/10
13=x/10
130=x
Nicole has $35.80 and spends $5.92 on a book. She puts half of the remaining money in her bank.
How much money does Nicole put in her bank?
$11.98
$14.94

35.80 - 5.92 = 29.88
29.88 divided by 2 gives you
14.94
Answer:
$14.94
Step-by-step explanation:
35.80-5.92=29.88

Step-by-step explanation:
A 12-foot ladder is placed 4 feet away from a house as shown.
A 12 foot ladder is leaning against a house to form angle x. The distance between the house and the bottom of the ladder is 4 feet. The angle between the house and the ground is 90 degrees.
What is the value of x, rounded to the nearest degree?
x ≈
°
According to the manufacturer, if the angle the ladder forms with the ground, x, is between 70° and 75°, then it meets safety standards.
Is this ladder being used safely?
Answer:
Answer: x = 71 degrees. Yes, the ladder meets safety standards
Discussion:
The problem describes a right triangle with hypotenuse 12, the side against the ground is 4, and the angle between those two sides is "x". For this triangle,
cosx = (side adjacent to angle) / hypotenuse
= 4 / 12
= 1/3
To find "x" take the inverse cosine of each side to find that :
x is approximately 70.52 degrees. That's 71 degrees rounded to the nearest degree.

Answer:
f(x)=0.5x+3.5, x<1
f(x)=-2x+6, x>1
Step-by-step explanation:
Find the Point of Interest, which is at x=1 because the direction changes. Find the slope (rise/run) of the line on the left which is 1/2 or 0.5. Find the y-intercept by plugging in the given point: (-3, 2). 0.5(-3)+c=2 so the y-intercept is 3.5. Do the same for the line on the right.

(-5m2 – 8) - (-3m² + m +2)
Answer: -2m2 -m - 10
Step-by-step explanation:
(-5m2 - 8) - (-3m2 + m + 2)
Everything is behind the (-) when you have a parenthesis chang the sign so and let the () so will be
-5m2-8 +3m2 - m -2
Now you are going to add or subtract numbers for the one the same letter ( base) and for the one that don't have a other letter (base) you will let it like this so will be
-5m2 + 3m2 = -2m2
-8 -2 = -10
-2m2 - m - 10
Hope helps

Mt. Calvary's budget for a swing set to be built for the Children's Church is $900. If the cost of the swing set should be at least one-fourth as much as the fort, how much can be spent on the fort and still build the swing set?
Answer:
[tex]Amount = \$4500[/tex]
Step-by-step explanation:
Represent Swing Set with S and Fort with F
Given
[tex]S = \$900[/tex]
[tex]S = \frac{1}{4}\ of\ F[/tex] --- S = one-fourth of F
Required
Determine the amount spent on both
Substitute 900 for S in [tex]S = \frac{1}{4}\ of\ F[/tex]
[tex]\$900 = \frac{1}{4} * F[/tex]
Multiply both sides by 4
[tex]4 * \$900 = \frac{1}{4} * F * 4[/tex]
[tex]4 * \$900 = F[/tex]
[tex]\$3600= F[/tex]
[tex]F = \$3600[/tex]
The total amount to be spent it:
[tex]Amount = F + S[/tex]
[tex]Amount = \$3600 + \$900[/tex]
[tex]Amount = \$4500[/tex]

What is the slope of the equation y = 5x - 7?
o
-7
o
7.
Answer:
slope = 5
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = 5x - 7 ← is in slope- intercept form
with slope m = 5
Answer:
The slope is 5.
Step-by-step explanation:
y=mx+b is the equation used to plot a line, where m is the slope and b is the y intercept.
An empty box weighs 200 g the boxes filled with party goody bags and now it weighs 6.2 kg each goodie bag weighs 100 and grams work out how many goody bags are inside the box
Answer:
60 goody bags
Step-by-step explanation:
1 kg = 1000 g
6.2 kg = 6,200 g
Empty box = 200 g
Box + goody bags = 6,200 g
Weight of Goody bags = Box + goody bags - empty box
= 6,200g - 200g
= 6,000 grams
Each goody bag = 100 g
how many goody bags are inside the box
Number of goody bag in the box = total weight of goody bag / weight of each goody bag
= 6,000 grams / 100 grams
= 60 goody bags
There are 60 goody bags in the box
