Answer:
Let the measures of three angles be 2x, 9x, 4x
Sum of the angles of a triangle = 180
2x+9x+4x = 180
15x = 180
x = 180/15 = 12
First angle = 2x = 2*12 = 24°
Second angle = 9x = 9*12 = 108°
Third angle = 4x = 4*12 = 48°

(-4,22)
Step-by-step explanation:
Answer:
(- 4, 22 )
Step-by-step explanation:
To determine which point lies on the graph, substitute the x- coordinate of the point into the equation and if the value obtained is equal to the y- coordinate of the point then it lies on the graph.
(1, - 2 )
y = - 4(1) + 6 = - 4 + 6 = 2 ≠ - 2 ← not on graph
(- 4, - 10 )
y = - 4(- 4) + 6 = 16 + 6 = 22 ≠ - 10 ← not on graph
(- 4, 22 )
y = - 4(- 4) + 6 = 16 + 6 = 22 ← lies on graph
(1, - 10 )
y = - 4(1) + 6 = - 4 + 6 = 2 ≠ - 10 ← not on graph

A line passes through the point (-4, 2) and has a slope of
Write an equation in slope-intercept form for this line.
Answer:
[tex]y=\frac{5}{4}x+7[/tex]
Step-by-step explanation:
We can start by setting up what we know of the slope-intercept equation, which is the slope.
[tex]y=\frac{5}{4}x+b[/tex]
Now, we can use the given point to find the y-intercept.
[tex]2=\frac{5}{4}(-4)+b\\ 2=-5+b\\b=7[/tex]
And now we are able to write the slope-intercept equation.
[tex]y=\frac{5}{4}x+7[/tex]
I hope this helps!

(7-(-2))/(0-8)
simplify
9/-8
simplify -9/8
now using y=mx+b, we need to find b. so we can plug in the coordinates of (0,7) or (8,-2). let's use (8,-2) because it involves more math.
y=mx+b
-2=(-9/8)(8)+b
multiply (-9/8) by 8 to get -9
-2=-9+b
add 9 to both sides
7=b
so our equation is now
y=-(9/8)x+7

Answer:
3. m∠A < 80°
Step-by-step explanation:
The exterior angle NGS, marked as 80°, has a measure that is the sum of the measures of the remote interior angles: GAN, GNA.
If we assume that angle measures cannot be zero, then we must have ...
m∠A +m∠N = 80°
m∠A = 80° -m∠N
Since m∠N > 0, the measure of angle A must be less than 80°.
This conclusion matches choice 3.

A standard showerhead in Marty's house dispenses 7 gallons of water per minute. Marty changed this showerhead to an energy-saving one. The equation shows the amount of water dispensed, y, as a function of the number of minutes, x, for the new showerhead. y = 3x How much water does Marty save each day with the change in showerheads if he uses the shower for 8 minutes each day? 4 gallons 12 gallons 32 gallons 53 gallons
Answer:
32 gallons
Step-by-step explanation:
A standard showerhead in Marty's house dispenses 7 gallons of water per minute. If he showers for 8 minutes, he uses:
1 minute = 7 gallons
8 minutes = x
x = 7 × 8 minutes = 56 gallons of water
We are told that:
Marty changed this showerhead to an energy-saving one. The equation shows the amount of water dispensed, y, as a function of the number of minutes, x, for the new showerhead. y = 3x
The equation for the energy saving shower:
y = 3x
Where x is the number of minutes spent in the shower
For 8 minutes
y = 3 × 8
y = 24 gallons
The gallons of water Marty saved each day with the change in showerheads if he uses the shower for 8 minutes each day is calculated as:
56 gallons - 24 gallons
= 32 gallons
An artist plans a sculpture by stacking two cubes. Write an algebraic expression the artist can use to find the volume of the sculpture. Then find the volume of the sculpture when x = 4cm. *Hint: V=s3
Answer:
[tex]V= 2x^3[/tex]
The volume is 128cm^3
Step-by-step explanation:
Given
[tex]Cubes = 2[/tex]
[tex]Sides = 4cm[/tex]
Required
Determine an expression for its volume
Find the volume
Volume of a cube is:
[tex]Volume = x^3[/tex]
Where x represents the length of a side
So, volume of 2 cubes would be:
[tex]V= x^3 + x^3[/tex]
[tex]V= 2x^3[/tex]
Solving (b): Volume when x = 4
Substitute 3 for x in [tex]V= 2x^3[/tex]
[tex]V = 2 * 4^3[/tex]
[tex]V = 2 * 64[/tex]
[tex]V = 128[/tex]
Hence, the volume is 128cm^3
