The graph of a linear function is shown on the coordinate grid below.
What are the slope and y-intercept of the linear function shown in the grid?
A) Slope = –0.4, y-intercept = –5
B) Slope = 2.5, y-intercept = –5
C) Slope = –2.5, y-intercept = 2
D) Slope = 0.4, y-intercept = 2
Answers
Answer:
B) Slope = 2.5, y-intercept = –5
Step-by-step explanation:
Given the following points on the grid, (-1.5, -8.75) and (3.5, 3.75), the slope can be calculated as follows using the formula, [tex] m = \frac{y_2 - y_1}{x_2 - x_1} [/tex]
Let,
[tex] (-1.5, -8.75) = (x_1, y_1) [/tex]
[tex] (3.5, 3.75) = (x_2, y_2) [/tex]
[tex] m = \frac{3.75 -(-8.75)}{3.5 -(-1.5)} [/tex]
[tex] m = \frac{3.75 + 8.75}{3.5 + 1.5} [/tex]
[tex] m = \frac{12.5}{5} [/tex]
[tex] m = 2.5 [/tex]
Slope = 2.5.
The y-intercept is the point at which the line intercepts the y-axis. On the graph, the line intercepts the y-axis at y = -5. Therefore, the y-intercept = -5.

Mr. Gatti is looking to buy some apples to bake a fresh & tasty apple pie. He goes to the store and sees two deals that are going on for apples: Deal A - 3/4 of a pound for $2.50 Deal B - LaTeX: 2\frac{2}{10}2 2 10 pounds for $5.25 1. Which is the better deal, and why? Explain your answer. Put your answer in $ per pound format
Answers
Answer:
Deal A is best
Step-by-step explanation:
Given
Deal A:
3/4 lb for $2.50
Deal B:
2/10 lb for $5.25
Required
Which deal is the better
To do this, we simply calculate the lb/dollar ratio
i.e.
[tex]Ratio = \frac{Amount}{Size}[/tex]
For Deal A:
[tex]Ratio = \$2.50/\frac{3}{4}lb[/tex]
[tex]Ratio = \$2.50 * \frac{4}{3}lb[/tex]
[tex]Ratio = \frac{\$10}{3}lb[/tex]
[tex]Ratio = \$3.33/lb[/tex]
For Deal B:
[tex]Ratio = \$5.25/\frac{2}{10}lb[/tex]
[tex]Ratio = \$5.25 * \frac{10}{2}lb[/tex]
[tex]Ratio = \frac{52.5}{2}lb[/tex]
[tex]Ratio = \$26.25/lb[/tex]
The better deal is the least expensive:
Hence: Deal A is better
You buy 80 stamps for 17 dollars some stamps were 15 cents each and the others were 25 cents each. how many of each kind did you buy
Answers
Answer:
30 of the 15 cent stamps and 50 of the 25 cent stamps
Step-by-step explanation:
Create a system of equations, where x is the number of 15 cent stamps and y is the number of 25 cent stamps:
x + y = 80
0.15x + 0.25y = 17
Solve by substitution by rearranging the first equation:
x + y = 80
x = 80 - y
Substitute 80 - y as x into the second equation:
0.15x + 0.25y = 17
0.15(80 - y) + 0.25y = 17
12 - 0.15y + 0.25y = 17
12 + 0.1y = 17
Solve for y:
0.1y = 5
y = 50
Plug in 50 as y into the first equation, and solve for x:
x + y = 80
x + 50 = 80
x = 30
So, you bought 30 of the 15 cent stamps and 50 of the 25 cent stamps
answer: ten 15¢ stamps and forty 20¢ stamps.

Davos has $150,000 to invest. His intent is to earn 7.5% interest on his investment. Davos will invest part of the money at 5.6% interest and part at 9.7% interest. How much does Paul need to invest in each option to earn a 7.5% return on the $150,000? Round to the nearest dollar.
Answers
Answer:
The amount invested on 5.6% interest = $80488
The amount invested on 9.7% interest = $69512
Step-by-step explanation:
Given that total amount of investment = $150,000
Let the amount invested on 5.6% interest = $[tex]x[/tex]
Now, amount invested on 9.7% interest = $(150000-[tex]x[/tex])
Total interest to be earned = 7.5%
Formula to be used:
[tex]Simple\ Interest = \dfrac{P\times r\times t}{100}[/tex]
Where, [tex]P[/tex] is the amount invested
[tex]r[/tex] is the rate of interest
[tex]t[/tex] is the time for which amount is invested.
As per question statement:
[tex]\dfrac{x\times 5.6}{100}+\dfrac{(150000-x)\times 9.7}{100}=\dfrac{150000\times 7.5}{100}\\\Rightarrow 5.6x-9.7x=150000(7.5-9.7)\\\Rightarrow 4.1x=150000\times 2.2\\\Rightarrow x = \dfrac{330000}{4.1}\\\Rightarrow x \approx \bold{\$80488}[/tex]
The amount invested on 5.6% interest = $80488
The amount invested on 9.7% interest = $150000 - $80488 = $69512

4. ∠JKL ≅ ∠JHG 4. Alternate interior angles
5. ∠GJH ≅ ∠KJL 5. Vertically opposite angles
6. ΔGHJ ≅ ΔLKJ 6. By ASA theorem of congruence
We have to prove the statement, ∠GHJ = ∠LKJ
Given; GH || KL, J is the midpoint of HK.
To prove; ∠GHJ = ∠LKJ
Given; J is the midpoint of HK,
By definition midpoint of a segment,
The midpoint is the middle part of the line segment J, it is equidistant from both endpoints it is the centroid of the segment of the endpoints.
JH ≅ HK
Then, by the property of alternate interior angles,
∠JKL≅ ∠JKH
Therefore, by the property of vertically opposite angles,
When two lines intersect they form four angles. Vertical angles are the angles that are opposite to each other. Any two intersecting lines form two pairs of vertical angles that are opposite to each other.
∠GJH ≅ KJL
By ASA congruence theorem,
When two triangles are congruent to each other - If two angles and the involved side of one triangle is equivalent to the two angles and the included side of the other triangle.
ΔGHJ ≅ ΔLKJ
Hence Proved.

What is the solution: –3(3x –2) = –30
Answers
Answer:
x=4
Step-by-step explanation:
–3(3x –2) = –30
Divide each side by -3
–3(3x –2)/-3 = –30/-3
3x –2 = 10
Add 2 to each side
3x –2+2 = 10+2
3x = 12
Divide each side by 3
3x/3 = 12/3
x = 4
Answer:
X = 4
Step-by-step explanation:
1: Distribute
-3 (3x - 2) = -30 (Multiply 3x and -2 by -3)
-9x + 6 = -30
2: Combine Like Terms
-9x + 6 = -30 (Subtract 6 from -30)
-9x = -36
3: Divide
-9x = -36 (Divide -36 by -9 to get x by itself)
x = -36 / -9
4: Solve
x = -36 / -9
X = 4

opp/ hyp = adj /hyp
Multiply each side by the hypotenuse
opp = adj
The opposite side must equal the adjacent
Since this is a right triangle
opp ^2 + adj ^2 = hypotenuse^2
opp ^2 + opp ^2 = hypotenuse^2
2 opp ^2 = hypotenuse^2
Take the square root of each side
sqrt(2 opp ^2) =sqrt( hypotenuse^2)
sqrt(2) opp = hyp
We know sin X = opp / hyp
sin x = opp / (sqrt(2) / hyp)
sin x = 1 / sqrt(2)
sin x = sqrt(2) /2
Taking the inverse sin of each side
x = sin ^-1 ( sqrt(2) /2)
