Answer:
x = [tex]\frac{15}{2}[/tex]
Step-by-step explanation:
Given
[tex]\frac{4x-1}{2}[/tex] = x + 7 ( multiply both sides by 2 to clear the fraction )
4x - 1 = 2(x + 7) ← distribute
4x - 1 = 2x + 14 ( subtract 2x from both sides )
2x - 1 = 14 ( add 1 to both sides )
2x = 15 ( divide both sides by 2 )
x = [tex]\frac{15}{2}[/tex]

Answer: The answer (4,3) or x=4 and y=3
please solve this equation and show work tysmmmm5(p+6)=8p
Answer:
P=10
Step-by-step explanation:
5p+30=8p
30=3p
10=p
Answer:
5 ( p + 6 ) = 8p
Distribute (multiply 5 by p and 6)
5p + 30 = 8p
Subtract 5p from both sides
30 = 3p
Divide by 3 to isolate variable
10 = p

1.) What is the relationship between angles 1, 2, and 3?b
Answer:
Exterior Angle Property of a Triangle
Step-by-step explanation:
According to exterior angle property of a triangle , the measure of any one exterior angle of a triangle is equal to the the sum of measure of it's opposite interior angles.
The relationship between angles 1, 2 and 3 is that they follows exterior angle principle. Therefore, ∠3 = ∠2 + ∠1
Exterior angle theoremThe exterior angle theorem states that the measure of an exterior angle is equal to the sum of the measures of the two remote interior angles of the triangle.
In other word, the measure of each exterior angle of a triangle is equal to the sum of the opposite and non-adjacent interior angles
Therefore, the angle 3 is related to angle 1 and 2(remote interior angles) by the exterior angles theorem. Mathematically, this can be represented as follows:
∠3 = ∠2 + ∠1

Which expression is equivalent to 4+5i•(2-7i)?
Answer:
(4 + 5i)(2 - 7i) = 8 - 28i + 10i + 35
= 43 - 18i
4 + 5i(2 - 7i) = 4 + 10i + 35
= 39 + 10i
The isosceles triangle has two sides with the same length. The base is one-half the length of a side. The expression which represents the perimeter, the distance around the triangle, is s + s + one-half s. What is the value of this expression if s = 8?
A triangle with 2 sides with length s.
Answer:
20 units
Step-by-step explanation:
s = 8
Perimeter = s + s + [tex]\frac{1}{2}*s[/tex]
[tex]= 8 + 8 + \frac{1}{2}*8[/tex]
= 8 + 8 + 4
= 20 units

Answer:
Step-by-step explanation:
Parallel lines have identical slopes and different y intercepts.
y = 3x + 2

C (the rate of change of f(x) is -1/2 and g(x) if 1/2
Step-by-step explanation:
i cant be 100% sure so take this with a grain of salt but if x was 1, f(x)'s rate of change (another word for slope) would be -1/2 whilst g(x)'s slope would be 1/2.

Look at the rectangle and the square
Ada says that the length of diagonal SQ is two times the length of diagonal OM.
Is Ada correct? Justify your answer and show all your work. Your work should state the theorem you used to find the lengths of the diagonals
Answer:
NO. Ada is not correct.
Step-by-step explanation:
Using Pythagorean Theorem, find the length of the diagonal of the rectangle and the square, respectively.
✔️Diagonal of the Rectangle:
[tex] a^2 + b^2 = c^2 [/tex]
Where,
a = 8 in.
b = 16 in.
c = hypotenuse (longest side of a right ∆)
Plug in the values into the equation
[tex] 8^2 + 16^2 = c^2 [/tex]
[tex] 64 + 256 = c^2 [/tex]
[tex] 320 = c^2 [/tex]
Take the square root of both sides
[tex] \sqrt{320} = \sqrt{c^2} [/tex]
[tex] 17.9 = c^2 [/tex] (nearest tenth)
Length of diagonal SQ = 17.9 in
✔️Diagonal of the Rectangle:
[tex] a^2 + b^2 = c^2 [/tex]
Where,
a = 8 in.
b = 8 in.
c = hypotenuse (longest side of a right ∆)
Plug in the values into the equation
[tex] 8^2 + 8^2 = c^2 [/tex]
[tex] 64 + 64 = c^2 [/tex]
[tex] 128 = c^2 [/tex]
Take the square root of both sides
[tex] \sqrt{128} = \sqrt{c^2} [/tex]
[tex] 11.3 = c^2 [/tex] (nearest tenth)
Length of diagonal OM = 11.3 in.
SQ is not two times the length of OM.
Therefore, Ada is not correct.
Answer:
No Ada is not correct
Step-by-Step Explanation:
The length of diagonal SQ is not two times the length of diagonal OM. When you split the rectangle using the diagonal you can make a right triangle and use the Pythagorean Theorem to the rest of it.
This would be the Rectangle:
a^2+b^2=c^2
8^2+16^2=c^2
64+256+c^2
320=c^2
√320
17.8
This would be the Square:
a^2+b^2=c^2
8^2+8^2=c^2
64+64=c^2
128=c^2
√128
11.3
Now when I divide these answers that I came up with I get 1.7 which is not equal to 2 therefore SQ is not two times bigger than OM.

Which linear equation matches this graphed line?
y = 2x + 5
y = 1/2x-5
y = 2x+5
y = 1/2x + 5
Answer:
I think one of the choices was entered incorrectly. You have y=2x+5 listed twice. I believe the answer is y=-2x+5
Step-by-step explanation:
5 is the y-intercept and it is a +5 because it is above the x-axis. Slope = rise/run. In this case the slope should be negative thus -2x. Hope this helps.

An angle measures 90° less than the measure of its supplementary angle. What is the measure of each angle?
Answer:
Supplementary angles add up to 180 degrees more than the other, you can formulate an equation 180=(100+x)+x80=2x so, x=40 the other angle is 100 degrees more. So, the angle lengths are 40 and 140 degrees

Answer:
A) 10/3
Step-by-step explanation:
substitute the y statement into the x statement and solve regularly.

Math Problem: Convert
Answer:
135°
Step-by-step explanation:
To convert from radians to degrees
degree = radian × [tex]\frac{180}{\pi }[/tex]
Thus for [tex]\frac{3\pi }{4}[/tex]
degree = [tex]\frac{3\pi }{4}[/tex] × [tex]\frac{180}{\pi }[/tex] ( cancel the π )
= [tex]\frac{3(180)}{4}[/tex]
= [tex]\frac{540}{4}[/tex]
= 135°
