Answer:
y=2x+11
Step-by-step explanation:
y-5=2(x+3)
y-5=2x+6
+5 +5
y=2x+11
Answer:
y = 2x + 11
Step-by-step explanation:
Slope-intercept form is y = mx + b.
Here we have y−5=2(x+3), in point-slope form.
Solve this for y: y = +5 + 2x+6, or
y = 2x + 11
the circumference of a circle is 4π ft. find its diameter in feet
Answer:
4 is the diameter
Step-by-step explanation:
Given:
C = 4π
Formula for circumference:
C = 2πr
Work:
C = 2πr
4π = 2πr
r = (4π)/(2π)
r = 2
Diameter:
d = 2r
d = 2(2)
d = 4

which values are solutions to the inequality -3(x)-4<2
Answer:
x>-2
Step-by-step explanation:
So, lets start by distrubuting the -3 to x:
-3x-4<2
Then lets just start solving. First lets add 4 to both sides to get -3x alone:
-3x<6
Now lets divide -3 from both sides to get x alone:
x<-2
There is one thing we must remember, however.
When dividing a inequality by a negative, the sign is flipped.
So in this case, the < is now >:
x>-2
This basically means a solution is any value greater than -2!
Hope this helps!
has a y-intercept of (0,2) and passes through the point (3,128)
Answer:
y = 42x + 2
Step-by-step explanation:
The equation of a line is expressed as y = mx+b
Slope = y2-y1/x2-x1
Slope = 128 - 2/3-0
Slope m = 126/3
Slope = 42
Since the y intercept is (0, 2), hence b = 2
Get the equation;
Recall that y = mx+b
y = 42x + 2
This gives the required equation
What is the value of x in the equation:

Please help me with 1,2,3,4 and show me how you get it the answers
Answer:
Step-by-step explanation:
Use the formula of distance between the two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex],
Distance = [tex]\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
1. Distance between A(3, 4) and B(8, 12),
AB = [tex]\sqrt{(8-3)^2+(12-4)^2}[/tex]
AB = [tex]\sqrt{25+64}[/tex]
= [tex]\sqrt{89}[/tex]
≈ 9.43
2. Distance between C(-2, 10) and D(3, -2),
CD = [tex]\sqrt{(3+2)^2+(-2-10)^2}[/tex]
= [tex]\sqrt{25+144}[/tex]
= [tex]\sqrt{169}[/tex]
= 13.00
3. Distance between X(20, 4) and Y(17, 0),
XY = [tex]\sqrt{(20-17)^2+(4-0)^2}[/tex]
= [tex]\sqrt{3^2+4^2}[/tex]
= [tex]\sqrt{25}[/tex]
= 5.00
4. Distance between E(2, -1) and M(6, 9),
EM = [tex]\sqrt{(2-6)^2+(-1-9)^2}[/tex]
= [tex]\sqrt{16+100}[/tex]
= [tex]\sqrt{116}[/tex]
= 10.77

2x-8=x+4. What would x be
[tex]2x - 8 = x + 4[/tex]
Collecting like terms,
[tex]2x - x = 4 + 8[/tex]
Since the signs change when its position changes.
[tex]x = 8 + 4 \\ x = 12[/tex]
Answer:
The value of x would be 12.
Step-by-step explanation:
2x - 8 = x + 4
2x - x = 4 + 8
x = 12

Do Now. Darren is standing on the top floor of a hotel which is 300 ft tall. He thought it would be fun to
drop a bouncy ball over the railing and see how long it would take to hit the ground. Explain how he
could determine this without actually performing the experiment. Then determine the answer
Answer:
Since he is so high up the ball would take longer to hit the ground because of how far down it has to go.
Step-by-step explanation:
Answer:
this is confusing but since the building is 300ft tall he can kinda estmate how long it will take

Answer:
[tex](\dfrac{1}{4})^{\dfrac{-3}{2}}[/tex] = 8
Step-by-step explanation:
The given expression is :
[tex](\dfrac{1}{4})^{\dfrac{-3}{2}}[/tex]
We know that,
[tex]\dfrac{1}{x}=x^{-1}[/tex]
So,
[tex](\dfrac{1}{4})^{\dfrac{-3}{2}}=(\dfrac{1}{2^2})^{\dfrac{-3}{2}}\\\\=(2^{-2})^{\dfrac{-3}{2}}\\\\=(2^{-1})^{-3}\\\\=2^3\\\\=8[/tex]
So, the value of the given expression is 8.

Make x the subject of the formula
y = ax2
PLZ HELP MEEE
Answer:
x = ± [tex]\sqrt{\frac{y}{a} }[/tex]
Step-by-step explanation:
Given
y = ax² ( divide both sides by a to isolate x² )
[tex]\frac{y}{a}[/tex] = x² ( take the square root of both sides )
x = ± [tex]\sqrt{\frac{y}{a} }[/tex]

What is the value of x?
Answer:
x = 5
Step-by-step explanation:
using the Pythagorean theorem:
x² = 13² - 12² = 169 - 144 = 25
x = √25 = 5
Answer:
x = 5.
Step-by-step explanation:
For a right triangle, use the Pythagorean Theorem, a² + b² = c², where a and b are the sides, and c is the hypotenuse.
a² + b² = c²
x²+ 12² = 13²
x² + 144 = 169
Subtract 144 from both sides.
x² = 25
x = 5.
Proof:
a² + b² = c²
5² + 12² = 13²
25 + 144 = 169
169 = 169.

what is the product of 3.4* 10^2 and 1.8* 10^3 expressed in scientific notation
Answer:
6.12 x 10⁵
Step-by-step explanation:
You just multiply 3.4 and 1.8 which gives 6.12
And for the notation you add the exponents 2 and 3 which give 5
Answer:
6.12 × 10^5.
Step-by-step explanation:
3.4 × 10² × 1.8 × 10³
To solve this, we can group.
[tex](3.4 * 1.8) * (10^2 * 10^3) =[/tex] [tex](6.12) *(10^5).[/tex]
Therefore,[tex](3.4 *1.8)*(10^2*10^3) = 6.12 * 10^5[/tex]

Answer:
6 runners
Step-by-step explanation:
Complete question
A relay race covers 1 1/2 kilometers, and each runner on a team will run 1/4 of a kilometer. How many runners are needed for a team?
Given that;
1 runner = 1/4 km
If a relay race covers 1 1/2 km, hence;
x runner = 1 1/2 km
Divide both expressions
1/x = (1/4)÷(1 1/2)
1/x = 1/4 ÷ 3/2
1/x = 1/4 * 2/3
1/x = 2/12
Cross multiply
2x = 12
x = 12/2
x = 6
Hence 6 runners are needed for the race
