Write an equation of the line that passes through (−2,1) and is parallel to the line y=3x−4.
Equation: y=
Answer:
y = 3x+7
Step-by-step explanation:
the slope of parallel lines are the same so the slope is 3
y-y1 = 3(x - x1)
y- 1 = 3(x- -2)
y-1 = 3x +6
y = 3x +7
Find the slope-intercept form of an equation of the line perpendicular to the graph of x – 3y = 5 and passing through (0, 6).
Answer:
y=-3x+6
Step-by-step explanation:
x-3y=5
y=1/3x-5/3
slope of perpendicular line is -3 (opposite reciprocals)
y=mx+b
x=0 and y=6
6=3x+b
6=3(0)+b
6=b
y=-3x+6

how many solutions does y=-7x+8 y=-7x-8 have?
Answer:
no solutions
Step-by-step explanation:
Given the 2 equations
y = - 7x + 8 → (1)
y = - 7x - 8 → (2)
Substitute y = - 7x - 8 into (1)
- 7x - 8 = - 7x + 8 ( add 8 to both sides )
- 7x = - 7x + 16 (add 7x to both sides )
0 = 16 ← not possible
This indicates the system has no solutions
Hey there!
The answer to your question is [tex]no[/tex] [tex]solutions[/tex]
To solve this, we will set the equations equal to eachother. We know that since the two expressions, [tex]-7x+8[/tex] and [tex]-7x-8[/tex] both equal [tex]y[/tex], then the expressions are equal. (Somebody comment what property that is, I forgot what it's called) So:
[tex]-7x+8=-7x-8\\[/tex]
Add [tex]8[/tex] to both sides:
[tex]-7x+16=-7x[/tex]
Add [tex]7x[/tex] to both sides:
[tex]16 = 0[/tex]
Therefore, there are [tex]no[/tex] [tex]solutions[/tex].

the cylinder has a height of 30cm and radius 11cm. work out the total surface area of cylinder
Answer:
total surface area=2832.66 cm^2
Step-by-step explanation:
11^2(3.14)x2=area of ends=760.26 cm^2
11x2x3.14=circumference=69.08 cm
69.08x30=area of side=2072.4 cm^2
2072.4+760.26=2832.66 cm^2
9 A rectangle of perimeter 42 cm is
pcm long and q cm broad. If the
difference between the length and
breadth is 9 cm. find
pand q
the area of the rectangle
Answer:
The correct answer is = p = 15 and q = 6.
Step-by-step explanation:
Given:
Perimeter of rectangle = 42 cm
p - q = 9 cm
length = p
width = q
we know:
Perimeter of rectangle= 2(l+w)
solution:
42 = 2(P+q)
21= p+q
Difference of p and q = 9 cm.
Then, P+q=21 .... 1
P-q=9 ....2
Adding both 1 and 2
2P = 30
P= 15cm and
q = 15-9
= 6cm
El día 12 de diciembre en Moscú se registró una temperatura de 13° bajo cero, a esa misma hora, en buenos Aires hacía una temperatura de 25 grados sobre cero. ¿Qué diferencia térmica existía en ese momento entre las dos ciudades? A.38 B.-38 C.12 D.-12
Answer:
A. [tex]38\ \text{grados}[/tex]
Step-by-step explanation:
La temperatura en Moscú es de 13 grados bajo cero. Entonces, la temperatura es de -13 grados.
La temperatura en Buenos Aires es de 25 grados bajo cero. Entonces, la temperatura es de 25 grados.
La diferencia de temperatura entre las dos ciudades es
[tex]25-(-13)=38\ \text{grados}[/tex]
La diferencia de temperatura entre las dos ciudades en un momento dado es [tex]38\ \text{grados}[/tex].

If m<1=(6x+25), and m<2=(x+5), find m<2
Answer:
Assuming they are equal to each other, X = -4
Step-by-step explanation:
6x + 25 = x + 5
Subtract 5 from both sides
6x + 20 = x
subtract 6x from the left side
20= 5x
divide by 5
-4 = x

sorry again but i'm having trouble on this one
Answer:
m∠PNO = 60°
m∠O = 33°
Step-by-step explanation:
∡NPO is 87° because it's a vertical angle with the 87° angle
3) ∡PNO is supplementary to the 120° angle (they must add to 180°)
4) m∠O = 180 - (60 + 87) = 33
is 25 meters longer then 35 yards

Which of the following equations could you solve by first adding six and then dividing by negative three?
6 - 3 x = -9
+ 6 = -9
-3 x - 6 = -9
3 x - 6 = -9
Answer:
-3x - 6 = -9 (The third answer)
Step-by-step explanation:
When solving for x, you have to undo each operation. When solving -3x - 6 = -9, you have to undo the -6 first. To do this, add 6 to both sides. Then, you must undo the -3x. To do this, divide by -3 from both sides.
