How many solutions does the equation 4x + 2(x - 5) = 3(2x - 4) have?
А.
no solution
B. exactly one solution
C. at least two solutions
D. infinitely many solutions
Answers
Answer:
C
Step-by-step explanation:
remove () and calculate the product
8x*(x-5)=3(2x-4)
distribute 8x through the ()
8x^2-40x=6x-12
move the expression to the left-hand side and change its sign
8x^2-40x-6x+12=0
collect like terms
8x^2-46x+12=0
determine the number of solutions using the discriminant D=b^2-4 a c
D=(-46)^2-4*8*12
simply the expression
D=1732
Since D>0, the quadratic equations has 2 real solutions

A conjecture and the flowchart proof used to prove the conjecture are shown.
Given: A B C D is a parallelogram.
Prove: Angle 1 is supplementary to angle 3.
Art: Parallelogram A B C D. Ray D B is drawn and is extended past vertex B. The ray forms an interior angles A D B and D B C and an exterior angle labeled as 3, adjacent to angle D B C. Angle A D B is labeled as 1, and angle D B C is labeled as 2.
Drag an expression or phrase to each box to complete the proof.
Answers
Answer:
∠1 is supplementary to ∠3.
Step-by-step explanation:
Given information: ABCD is a parallelogram.
Prove: ∠1 is supplementary to ∠3.
Proof:
∠1 = ∠ADB
∠2 = ∠DBC
∠3 = exterior angle adjacent to angle D B C.
Statement Reason
∠2 is supplementary to ∠3 Linear pairs
m∠2+m∠3=180° Definition of supplementary angles
Alternative interior angles
m∠1+m∠3=180° Substitute property of equality
∠1 is supplementary to ∠3 Definition of supplementary angles
All perfect squares are divisible by 2.
A.) true
B.) False, counterexample of 16
C.) False, counterexample of 15
D.) False, counterexample of 25
Answers
Answer:
the correct answer is C
Step-by-step explanation:
because the square root of 15 is 3.8 and 3.8 isnt divisible by 2
The reason for that is because A is not true, B is not a counterexample, C is not a square, so D is the answer.

What is the slope of this line?
A. 3
B. -1/3
C. -3
D. -2
E. 4
Answers
Answer:
-3
Step-by-step explanation:
Pick two points on the graph, lets go with (0, 4) and (1, 1)
y = mx + b
m is the slope and to figure it out use below formula
m = (y₂ - y₁) / (x₂ - x₁)
= (1 - 4) / (1 - 0)
= -3 / 1
= -3
Answer:
C. -3
Explanation:
Given problem;
To solve for the slope of the line;
The slope of a line is the vertical distance to the horizontal displacement on a line.
Slope = [tex]\frac{Vertical distance}{horizontal displacement}[/tex]
For lines such as this, we use the formula below;
Slope = [tex]\frac{y_{2} - y_{1} }{x_{2} - x_{1} }[/tex]
To find the slope reference the image attached;
point 1 (0,4) x₁ = 0 y₁ = 4
point 2 (2,-2) x₂ = 2 y₂ = -2
Now input the parameters and solve;
Slope = [tex]\frac{-2 - 4}{2 - (0)}[/tex] = [tex]\frac{-6}{2}[/tex]
Slope = -3
The slope of the line is -3

Answer:
5.319149 oz per dollar
Step-by-step explanation:
This is a fraction equal to
10 oz ÷ 1.88 dollars
We want a unit rate where
1 is in the denominator,
so we divide top and bottom by 1.88
10 oz ÷ 1.88
1.88 dollars ÷ 1.88
=
5.319149 oz
1 dollar

Two friends race. The first friend gets a head start and runs at a steady rate of 0.20 miles per minute. The second friend waits 1 minute and then runs at a steady rate of 0.25 miles per minute. How long will it take for the second runner to catch up with the first?
Answers
Step-by-step explanation:
In this problem we are expected to solve for the time taken for the second person to meet with the first.
given that
first person's speed=0.2mph
let time taken be= x
we know that
velocity= distance/time
0.2=distance/x
distance=0.2x----1
second person's speed= 0.25mpm
time taken=x-1
we know that
velocity= distance/time
0.25=distance/x-1
distance=0.25(x-1)
distance=0.25x-0.25-----2
equating equation 1 and 2 we have
0.2x=0.25x-0.25
0.2x-0.25=-0.25
-0.05x=-0.25
divide both sides by -0.05 we have
x=-0.25/-0.05
x=5
we know that the second person's time is described by
=x-1
=5-1=4min
The second person will catch up after 4 minutes

What are trigonometric ratios in terms of a right-angle triangle?We know a right-angled triangle has three sides they are -: Hypotenuse,
Opposite and Adjacent.
We can remember SOH CAH TOA which is,
sin = opposite/hypotenuse, cos = adjecen/hypotenuse and
tan = opposite/adjacent.
Given, A mountain has a 20-degree slope and is 1 mile tall and we have to hike the mountain so we want to know the distance.
Here hypotenuse is the distance we have to hike and according to the reference, the angle opposite has a distance of 1 mile.
We know sin = opposite/hypotenuse.
sin20° = 1/hypotenuse.
0.342 = 1/hypotenuse.
hypotenuse = 1/0.342.
hypotenuse = 2.92 miles.
