Answer:
-2 because rise over run is -2/1 or -2
Step-by-step explanation:
Answer:
-2
Step-by-step explanation:
The rate of change is the slope.
A slope that goes down to the right is negative. This line has a negative slope.
Now we will find the exact value of the slope.
slope = rise/run
rise = vertical distance (up is positive; down is negative)
run = horizontal distance (right is positive; left is negative)
Start at an easy-to-read point. Let's start at (0, 1) which is the y-intercept.
Now we need to go to another easy-to-read point. Let's use (1, -1) as our second point.
(By easy-to-read points, I mean points on grid line intersections whose coordinates can be read easily off the graph.)
We need to go from (0, 1) to (1, -1) by only moving vertically and horizontally. Start at (0, 1). We go vertically down 2 units and then horizontally right 1 unit to get to (1, -1). Going vertically down 2 units is a rise of -2. Going horizontally right 1 unit is a run of +1.
slope = rise/run = -2/1 = -2
slope = -2
The rate of change is the slope.
Answer: rate of change = -2

It costs $3.60 to buy one lb of candy. How much would it cost to purchase 5 lbs of candy?
Answer:
18$
Step-by-step explanation:
The answer is 18$ because you multiply 3.60$ by 5 lbs
1. Find the cost of 3.5 yards of fabric if the fabric is priced at $6.00 per yard.
$210.00
$1.71
$21.00
$17.10
$21.00
Step-by-step explanation:
if 1 yard equal 6 dollars
do 6 times 3 = 18
and half of 6 is 3
add 18+3=21 dollars

Based on their own blood types a couple has a 0.75 probability of having a child with type A blood. If the couple has 4 children, what is the probability that they will have 2 children with type A blood?
A. 0.07
B. 0.21
C. 0.56
D. 0.75
Answer:
B. 0.21
Step-by-step explanation:
https://stattrek.com/online-calculator/binomial.aspx
put in 75% for success rate
4 for the amount of trials because that is the total of kids the couple has
2 for number of successes for how many kids would get Type A blood
once calculated you get.21 or answer B
2. How many solutions to the equation 2x +2 = 2(x+3)
O 1 solution
O Infinitely many solutions
O No solution
Answer:
O No solution
Step-by-step explanation:
2x +2 = 2(x+3)
Distributer the 2 on the right side.
2x + 2 = 2x + 6
Subtract 2x from both sides.
2 = 6
2 = 6 is a false statement.
Since we did two legal steps to solve the equation, and we ended up with a false statement, that means this equation has no solution.
Answer: O No solution

I'm really struggling with this problem can someone please give me an examples like this problem or explain how to solve it an problems like it.
Answer:
Step-by-step explanation:
Ok so I'm not 100% sure how to solve this but what I would do is use the equation a^2 + b^2 = c^2 this equation is used to solve for the hypotenuse or the longest side of a triangle. To find a^2 you would do (21+15)^2 (Also this symbol ^ is the power symbol) and the answer would be 1296. b^2 would be 25^2 or 625. The equation turns out to be 1296 + 625 = c^2. c^2 (or x in this case) would be 1921. To find just c and not c^2 you would find the square root of 1921 which is 43.8292140016 or if rounded would be 43.8. Also this might not help if I misinterpreted the question...

what is 4x+3x-12+1x
Answer:
8x-12
Hope it helped plz mark me brainliest PlzPlz
Answer:
8x-12
Step-by-step explanation:
You need to find a number/numbers that have the same variable if the variable is the same then you can add or subtract them
You can add 4x, 3x and 1x
4x plus 3x plus 1x is 8x
Since -12 is alone you can leave it as it is
8x-12
Solve using proportions.
The triangles are similar, find the length of side (k) using a proportion; having ratios within the two figures.
Note: If someone could please answer before this upcoming Monday.
Answer:
7.8 = k
Step-by-step explanation:
Since the figures are similar, we can use proportions
c k
----- = -------
b j
Substituting the values in
6.5 k
----- = -------
4 4.8
Using cross products
6.5 * 4.8 = 4k
31.2 = 4k
Divide each side by 4
31.2/4 = 4k/4
7.8 = k

-3s(s - 10) + 7(-2s -1)
Answer:
-3s^2+16s-7
Step-by-step explanation:
-3s(s - 10) + 7(-2s -1) --> (-3s^2+30s)+(-14s-7) ---> -3s^2+16s-7
DO multiplication them convert like terms
Answer:
-3s² + 16s - 7
Step-by-step explanation:
Remember to follow FOIL. FOIL stands for (First, Outside, Inside, Last).
First, distribute -3s to s and -10, and 7 to -2s and -1:
-3s(s - 10) = -3s² + 30s
7(-2s - 1) = -14s - 7
Next, combine like terms:
-3s² + 30s - 14s - 7
-3s² + (30s - 14s) - 7
-3s² + 16s - 7
-3s² + 16s - 7 is your answer.

Find the area of the composite figure
Step-by-step explanation:
You're only finding half of a circle but since you have 2, it is possible to just do the area of a circle which is [tex]\pi r ^{2} [/tex]
3.5 x 3.5 = 12.25
Because the radius of your circle is 3.5m but there are 2 of them you subtract 7 from 18 which give you 11:
Then you multiply 11 by 7.
= 77
Then add it all together.
[tex]a = (77 + 12.25\pi)m^{2} [/tex]

x^2 - 55 = 26
Answer:
x = ±9
Step-by-step explanation:
x² - 55 = 26
+55 + 55
x² = 81
x = √81
x = ± 9
Answer:
x = 9, -9
Step-by-step explanation:
x^2 - 55 = 26
x^2 = 81.
Now, you might think that x = 9, but don't be fooled. -9 squared is also equal to 81.
So, x = 9, -9

Answer:
130°
Step-by-step explanation:
∠JDG and ∠EDF are opposite angles. The measures of arcs for opposite angles always add up to 180°. Since the arc for ∠JDG is 50°, the arc for ∠EDF has to be 130°, because 50 + 130 = 180.
