Answer:
Slope = -4
Step-by-step explanation:
Let us solve the question
∵ The slope of the line is m = Δy/Δx
∵ Δy is the change of y ⇒ Δy = y2 - y1
∵ Δx is the change of x ⇒ Δx = x2 - x1
→ Choose from the table x1, y1 and x2, y2
∵ x1 = -3 and y1 = 12
∵ x2 = -2 and y2 = 8
→ Use them to find Δx and Δy
∵ Δx = -2 - (-3) = -2 + 3 = 1
∴ Δx = 1
∵ Δy = 8 - 12 = -4
∴ Δy = -4
→ Use them to find the slope
∵ m = Δy/Δx
∴ m = [tex]\frac{-4}{1}[/tex]
∴ m = -4
∵ m is the slope of the line
∴ The slope of the line is -4

Need HELP ASSAP -8/5 times -5/1
Answers
Answer:8
Step-by-step explanation: negative times negative =positive
and times 8/5 by 5/1 .
When multiplying fractions, simply multiply the numerators together and multiply the denominators together.
-8 * -5 = 40
5 * 1 = 5
-8/5 * -5/1 = 40/5
40/5 = 8

Answer:
None of the Above
Step-by-step explanation:
Key Skills required are: One Variable Equations, Supplementary Angle Pairs, Substitution, and Triangles.
1) To find the measure of Angle C, we first need to find the measure of angle DBC and Angle D.
2) We are given that Angle EBA is x and Angle EBD is 4x+13 and Angle D is 3x + 9 (we will use Angle D later in the problem)
3) Now, we need to use the fact that Angle EBA and Angle EBD are supplementary (they form a linear pair, so they are supplementary).
A pair of supplementary angles add up to 180 degrees (as they form a straight angle).
4) x + 4x + 13 = 180
5) Combine like terms --> 5x + 13 = 180
6) Move 13 to the other side --> 5x = 167
7) Divide by 5 and solve for x: x= 33.4
8) Now we got that x is 33.4, we can get the measure of angle DBC and Angle D.
9) Angle DBC is congruent to Angle EBA. So to find the measure of DBC we need to find the measure of Angle EBA. EBA is just x, so it is 33.4 degrees
10) Therefore, Angle DBC also measures 33.4 degrees.
11) To find angle D, we substitute x into 3x + 9 (We are given angle D is 3x + 9 based on the problem)
12) 3(33.4) + 9 = 100.2 + 9 = 109.2
13) Now we use the interior angles sum of a triangle to find Angle C.
The interior angles of a triangle sum up to 180 degrees.
14) With the statement above we can make this equation: 109.2 + 33.4 + Angle C = 180
15) Simplify by combining like terms: 142.6 + Angle C = 180
16) 37.4 degrees would be the measure of C, so I feel it would be none of the above.

The expression p + 0.08p represents the total cost of an item with an initial price of p, plus an 8% sales tax. What is the total cost of an item with an initial price of $90?
Answers
Answer:
$97.2
Step-by-step explanation:=Given
The expression p + 0.08p
where P= the initial price
let y be the total cost, so that
y=p + 0.08p
for p=$90
y=90+0.08*90
y=90+7.2
y=$97.2
Hence the total cost for a $90 price is $97.2

6x - 5x = 14
x = 14

m∠A = m∠C = 140° ÷ 2 = 70°

Doug has two German Shepherds. The
larger dog weighs 70 1/2 pounds. If the
smaller dog weighs 75% as much as the
larger dog, find the smaller dog's weight.
wait ugh i asked the wrong question help pls and thank you
Answers
Answer:
52 7/8 pounds
Step-by-step explanation:
Find the smaller dog's weight by multiplying the larger dog's weight by 0.75:
70.5(0.75)
= 52.875 or 52 7/8 pounds
So, the smaller dog weighs 52 7/8 pounds
The required weight of the smaller dog is 52.875 pounds.
Given that,
Doug has two German Shepherds. The larger dog weighs 70 1/2 pounds. If the smaller dog weighs 75% as much as the larger dog, To find the smaller dog's weight.
In mathematics, it deals with numbers of operations according to the statements.
What is percentages?The percentage is the ratio of the composition of matter to the overall composition of matter multiplied by 100.
Here,
Let the weight of the smaller dog be x,
The weight of the smaller dog is 75% of the larger dog
x = 75% of 70 1/2
x = 0.75 * 70.5
x = 52.875
Thus, the required weight of the smaller dog is 52.875 pounds.
