Answer:
X = 4
Step-by-step explanation:
7x + 3 = 31
Step 1: Subtract 3 from both sides.
7x + 3 - 3 = 31 - 3
7x = 28
Step 2: Divide both sides by 7.
7x/7 = 28/7
Therefore, the answer is X = 4

Use point-slope form to write the equation of the line with a slope of 5/2 that goes through the point (-3,-6).
Answer:
4, (2,-4)
m= 5,(1,)

Answer:
[tex]y+6=\frac{5}{2} (x+3)[/tex]
Step-by-step explanation:
point-slope formula: [tex]y-y_1=m(x-x_1)[/tex]
where m = slope and the point would be [tex](x_1,y_1)[/tex]
point-slope form: [tex]y+6=\frac{5}{2}(x+3)[/tex]

Answer:
106°
Step-by-step explanation:
By exterior angle theorem:
[tex]m \angle \: 1 = 62 \degree + 44 \degree \\ \\ m \angle \: 1 = 106 \degree[/tex]
Step-by-step explanation:
Let the unknown angle in the triangle be x.
x + 44 + 62 = 180(sum of angles in a triangle)
x + 106 = 180
x = 180 - 106
x = 74
Angle 1 + x = 180 (Sum of angles on the same straight line)
angle 1 + 74 = 180
Angle 1 = 180 - 74
= 106

what is 1/3(w+18)=12 using distributive property?
Answer:
w = 18
Step-by-step explanation:
Given
[tex]\frac{1}{3}[/tex] (w + 18) = 12 ← distribute parenthesis on left side
[tex]\frac{1}{3}[/tex] w + 6 = 12 ( subtract 6 from both sides )
[tex]\frac{1}{3}[/tex] w = 6 ( multiply both sides by 3 to clear the fraction )
w = 18
r= 26, h = 16, S = ?
Answer:
S = 6
I think
Answer:
s=6
Step-by-step explanation:
if you are figuering it out in order then r=26 then you subtract 10 and get h=16 so then you subtract 6 more and get s=6
The sixth grade art students are making a mosaic using tiles in shapes of right triangles. Each tiles has the leg measures of 5.2 cm and 6 cm. If there are 150 tiles in the mosaic, what is the area of the mosaic?
Given:
Each right triangular tiles has the leg measures of 5.2 cm and 6 cm.
There are 150 tiles in the mosaic.
To find:
The area of the mosaic.
Solution:
We know that, the area of a triangle is:
[tex]A=\dfrac{1}{2}\times Base\times height[/tex]
So, the area of Each right triangular tile is:
[tex]A=\dfrac{1}{2}\times 5.2\times 6[/tex]
[tex]A=\dfrac{1}{2}\times 31.2[/tex]
[tex]A=15.6[/tex]
There are 150 tiles in the mosaic. So, the area of the mosaic is:
[tex]Area=15.6\times 150[/tex]
[tex]Area=2340[/tex]
Therefore, the total area of the mosaic is 2340 cm ².

Write the Equation of the line in fully simplified slope- intercept form
Answer:
y=-6/5x-2
Step-by-step explanation:
We are given points (5,-8) and (-5,4)
Slope = m = (y₂-y₁)/(x₂-x₁) = (-8-4/(5-(-5)) = -12/10 = -6/5
Y-intercept = b = (0,-2)
Final equation: y=-6/5x-2
Answer:
y=-6/5x-2
Step-by-step explanation:
y=mx+b
Its sloping downwards, so a negative slope.
two points: (-5,4) and (5,-8)
---------------------------------------------
so first find the slope.
y2-y1 / x2-x1 <= formula
so: -8-(4) / 5-(-5)
which becomes => -12/ 10
which is 6/5 the slope is 6/5
------------------------------------------
plug this into y=mx+b, where m is the slope
so: y=6/5x+b
------------------------------------------
obviously b is the y intercept, where the line meets y
the y intercept is -2
sooooooo final answer is
----------------------------------
y=6.5x+(-2)
-----------------------------------
Negative slope, so becomes y=6/5x-2

Find the maximum and minimum values of the function. y=1/2sin2x
Answer:
(-1/2,1/2)
Step-by-step explanation:
Normally for sinx amplitude is 2 (1 +1). In the case when it is half sine amplitude is halved, therefore 0.5 +0.5 = 1 Paramers alpha = 2x does not matter because it only stretches the graph horizontally.

when you are given a zero of a function and told that it has a multiplicity of 3, what does that mean?
Answer:
the zero of a function is what value you can plug in and get 0 as the answer.
having a multiplicity of 3 means that the zero is there 3 times so if your zero is 2 with multiplicity 3 then (x-2)^3 is what it looks like
