Answer:
The slope of the line is m = −11/3 ≈ −3.66666666666667 .
Step-by-step explanation:
The slope of a line passing through two points P=(x1,y1) and Q=(x2,y2) is given by m=y2−y1x2−x1.
We have that x1=−6, y1=7, x2=−3, y2=−4.
Plug the given values into the formula for a slope: m=−4−(7)−3−(−6)=−113.
Now, the y-intercept is b=y1−mx1 (or b=y2−mx2, the result is the same).
b=7−(−113)(−6)=−15
Finally, the equation of the line can be written in the form y=b+mx:
y=−15−11x3

Determine if each pair of animals has the same ratio of body length to tail length. Explain your reasoning.
Answer:
Hamster and lemming has about the same body to tail ratio. Since, their body to tail ratios is about 20%. However opossum and prairie dog do not at all. The opossum is about 73.47% and the prairie dog is about 14.29%.
Step-by-step explanation:
Answer:
Hamster and lemming have the same ratio of 1/5 and the others are unequal.

Find the measures of the complementary angles that satisfy each case:
The measure of the first angle is 40° less than the measure of the second.
Answer:
first - 25 degrees, second - 65 degrees
Step-by-step explanation:
I forgot the pic, but somebody help me
Answer:
1) The value of x is:
2) The degree for angle 1 is: 59°
3) The degree for Angle 2 is: 121°
Step-by-step explanation:
First we must find x, to do that we must find out what we are given:
m<1 = (2x + 23)°
m<2 = (7x - 5)°
Now we must see if there is any info that can help us find the angles:
Angle 1 and 2 are supplementary.
The word 'supplementary' is very important as it can help us evalute how to set up our problem.
Supplementary means the sum of 2 angles that create a 180°
So our measures will = 180°
(2x + 23) + (7x - 5) = 180°
Now we must try and find the value of x:
1) Remove the parenthesis, and combine like terms:
2x + 7x + 23 - 5 = 180°
9x + 18° = 180°
- 18° = -18°
---------------------
9x = 162°
2) Divide both sides by 2 in order to get 'x' value by itself:
[tex]\frac{9x}{9}=\frac{162}{9}[/tex]
[tex]x=18[/tex]
Your value of x is 18.
Now you must substitue the value of x into you measures, to get your angles:
(2x + 23)°
2(18) + 23
36 + 23
= 59°
(7x - 5)°
7(18) - 5
126 - 5
= 121°
Is this statement true? Let's find out!
121° + 59° = ?
= 180°
It is true.
A line is represented by the equation y=x-7. What is the y-intercept of the line?
Answer: -7
In the slope-intercept format y = mx+b, b is always the y-intercept. If it is with a positive sign, the y-intercept is positive and if it is negative then the y-intercept is negative.
If b = 3, then b -2 is equivalent to _____.
a. -6
b. 1/9
c. 9
d. -9
Wherever you see 'b', replace it with 3, since b = 3
So,
b^(-2) = 1/(b^2)
b^(-2) = 1/(3^2)
b^(-2) = 1/9
Solve for c ) if you could help I would appreciate

3x+8(2x - 6) = 2 + 14x
Answer:
x=10
Step-by-step explanation:
Simplifying 3x + 8(2x + -6) = 2 + 14x
Reorder the terms: 3x + 8(-6 + 2x) = 2 + 14x 3x + (-6 * 8 + 2x * 8) = 2 + 14x 3x + (-48 + 16x) = 2 + 14x
Reorder the terms: -48 + 3x + 16x = 2 + 14x
Combine like terms: 3x + 16x = 19x -48 + 19x = 2 + 14x
Solving -48 + 19x = 2 + 14x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-14x' to each side of the equation. -48 + 19x + -14x = 2 + 14x + -14x Combine like terms: 19x + -14x = 5x -48 + 5x = 2 + 14x + -14x
Combine like terms: 14x + -14x = 0 -48 + 5x = 2 + 0 -48 + 5x = 2
Add '48' to each side of the equation. -48 + 48 + 5x = 2 + 48
Combine like terms: -48 + 48 = 0 0 + 5x = 2 + 48 5x = 2 + 48
Combine like terms: 2 + 48 = 50 5x = 50
Divide each side by '5'. x = 10
Simplifying x = 10

bowl contains candies of the same size in three flavors: orange, strawberry, and pineapple. If the probability of randomly pulling out an orange candy is fraction 1 over 9 , and the probability of randomly pulling out a strawberry candy is fraction 2 over 9 , what is the probability of randomly pulling out a pineapple candy? (5 points)
Group of answer choices
fraction 3 over 9
fraction 2 over 9
fraction 6 over 9
fraction 5 over 9
Answer:
5 to 9
Step-by-step explanation:
Answer:
To find this add 3 and 1 together. This gives you 4. Then, you subtract 4 from 9. The answer is 5. Therefore, the probability to pull out a pineapple candy would be 5/9.

If granola costs $2.20 per pound, how much does 0.8 pound of granola cost?
$1.40
$1.76
$2.28
$2.75
Answer:
$1.76
Step-by-step explanation:
when you multiply 2.20x 0.8 you get 1.76. at first I thought division was needed, but the answer to 2.20/0.8 is 2.75- which is more than the original cost. (sorry if this is confusing but) 0.8 pound is less than 1 pound, so the answer would need to be less than 2.20.
If the measure of <3 is 117 degrees, what is the measure of <7?
Answer:
117
Step-by-step explanation:
The answer is 117 because angle 3 and 7 are corresponding so they have the same measure
Hope this helps dude ^-^
Answer: the measure of <7= 117
Step-by-step explanation: they zig zag so angle of 2,3,6 and 7 equal 117
while 1,4,5 and 8 equal 63( you can get 63 by doing 180-117) all angles side by side equal 180, so for example <1 and <2 equal 180, <3 and <4 equal 180.

Keira divided 123.52 by 3.2 and got 38.6. Without using a calculator, how could she check to determine if her answer is reasonable?
NO SAMPLE RESPONSE FROM EDGINUTY
The solution to the quotient of 123.52 by 3.2 is 38.6
Decimals and fractionsGiven the expression solved by Keira as;
123.52/3.2
Convert the decimals to fractions
123.52 = 12352/100
3.2 = 32/10
Substitute
123.52/3.2 = 12352/100÷ 32/10
123.52/3.2 = 12352/100 × 10/32
123.52/3.2 = 12352/320
123.52/3.2 = 38.6
Hence the solution to the quotient of 123.52 by 3.2 is 38.6
