What is the slope of the line that passes through the points (3,-2) and (1,5)?
Answer:
-7,2 I believe :)
Step-by-step explanation:
Rise over run
Put into an equation, y1-y2/1-x2
so its
-2-5/3-1 which gives you the answer of -7/2 :)
Answer:
m= 7/-2
Step-by-step explanation:
Use the slope formula.
y2 - y1 = 5 -- 2 = 7
x2 - x1 = 1 - 3 = -2
m = 7/-2
solve the inequality
7y+2<5y+12
Answer:
y < 5
Step by step:Step 1: Subtract 5y from both sides.
7y+2−5y<5y+12−5y
2y+2<12
Step 2: Subtract 2 from both sides.
2y+2−2<12−2
2y<10
Step 3: Divide both sides by 2.
[tex]\frac{2y}{2}[/tex] < [tex]\frac{10}{2}[/tex]
= y < 5
what is the slope and y-intercept of this graph?
Answer:
Slope is 2
Y-intercept is 7
Step-by-step explanation:
To find the slope we take any two points from the table
and use it in the formula :
[tex]m=\frac{y_2-y_1}{x_2-x_1} \\[/tex]
we take the points (0,7) and (1,9)
now we put these points in the formula and it becomes
[tex]m=\frac{9-7}{1-0}[/tex]
[tex]m=2[/tex]
so our slope which is m is 2 and now for the y-intercept we use the standard equation
[tex]y=mx+c[/tex]
where c is the y-intercept
we use the value of m which is 2 and use any point from the table lets take (0,7)
[tex]y=mx+c\\7=(2)(0)+c\\7=c[/tex]
our y-intercept which is c is 7
so finally our slope is 2 and y-intercept is 7

The transformation formula of a horizontal-facing parabola is:
x = ±a(b(y - k)) + h, where the vertex is at (h, k).
Looking at the graph, we can see a vertex at (-2, -3) with a stretch of 2. The graph is also pointed towards the RIGHT, which means that the coefficient "a" must be positive. Therefore:
The only logical answer choice is B, or x = 2(y + 3)² - 2.
The formula indicates that:
* Vertex at (-2, -3)
* Stretch of 2
* Right-facing parabola

jamil buys 4 books and some pens each book costs £5.95 each pen costs £2.35 the toal costs of the books and the pendulum is £37.90 work out how many pens jamil buys
Answer:
9.68
Step-by-step explanation:
it makes sense when u tink about ot
Answer:
Jamil buys 6 pens.
Step-by-step explanation:
Jamil buys 4 books and each book costs £5.95. With 5.95+5.95+5.95+5.95 = £23.80. We have the total price for the books. The total cost of books and pens is £37.90 and each pen costs £2.35. If we keep adding £2.35 to our £23.80, we will get £37.90. If we add 23.80+2.35+2.35+2.35+2.35+2.35+2.35 = £37.90. We now have our total amount, and the prices of the amount of books and pens Jamil bought. Jamil bought 6 pens as it equals to £37.90.

Please help! Only if you KNOw, I’m confused
Answer:
40
Step-by-step explanation:
1.Kknow the following information;
Remember, the sum of degrees of angles in a triangle is 180.
So say if a traingle contained;
<1, <2, <3,
Then:
<1 + <2 + <3 = 180
2. State the given, and set up an equation;
In this case, it is given that;
<1 = 115
<2 = 25
Therefore, set up the equation;
115 + 25 + <3 = 180
3. Solve the equation;
115 + 25 + <3 = 180
Simplify,
140 + <3 = 180
Inverse operations,
140 + <3 = 180
-140 -140
<3 = 40

Lane is making accessories for the soccer team. He uses 721.54 inches of fabric on headbands for 41 players and 2 coaches. He also uses 361.21 inches of fabric on wristbands for just the players. How much fabric was used on a headband and wristband for each player? Please answer quick pls
Answer:
16.78 inches of fabric was used for headbands for each player and 8.81 inches of fabric was used for wristbands for each player
Step-by-step explanation:
Lane is making accessories for the soccer team.
For headbands
He uses 721.54 inches of fabric on headbands for 41 players and 2 coaches.
Hence:
Let the number of inches used for headbands be represented by x
41x + 2x = 721.54
43x = 721.54
x = 721.54/43
x = 16.78 inches
Hence the number of inches used to make head band for 1 player is 16.78 inches
He also uses 361.21 inches of fabric on wristbands for just the players.
We have 41 players hence:
41 players = 361.21 inches
1 player = x
41 × x = 1 × 361.21 inches
x = 361.21 inches/41
x = 8.81 inches
8.81 inches of fabric was used for wristbands for each player.
Hence:
16.78 inches of fabric was used for headbands for each player and 8.81 inches of fabric was used for wristbands for each player
The equation for this graph is y = x +
Answer:
y=3x+2
Step-by-step explanation:
The y intercept is 2. Therefore, we can plug 2 into b in y=mx+b because b is a y intercept.
The slope is 3 because if you go up 3 and right to the one (rise over run) the line will go through it. You can also make is -3 over -1 but that would just equal 3.
Hope this helps!
