The solution to the expression when x = 3 is 0
What is an equation?An equation is an expression that shows the relationship between variables and numbers.
Given the diagram, the small white squares represent 1, while the big shaded rectangle represent -x.
The diagram shown represents the expression:
-x + 1 + 1 + 1 (they is one big shaded rectangle and three white small squares)
= -x + 3
Substituting x = 3 gives:
= -(3) + 3
= 0
The solution is 0

The first equation in a system is 5x + 2y = –4. Which equation gives a system with no solution? A. y = 2x + 6 B. y = 1/4x – 2 C. y = 2x + 7 D. y = –5/2x – 3
Given:
The first equation of the system of equations is
[tex]5x+2y=-4[/tex]
To find:
The equation that gives a system with no solution.
Solution:
We have,
[tex]5x+2y=-4[/tex]
It can be written as
[tex]2y=-5x-4[/tex]
[tex]y=\dfrac{-5x-4}{2}[/tex]
[tex]y=-\dfrac{5}{2}x-2[/tex]
On comparing this equation with slope intercept form [tex]y=mx+b[/tex], we get
[tex]m=-\dfrac{5}{2},b=-2[/tex]
It means the slope of the line is [tex]-\dfrac{5}{2}[/tex] and the y-intercept is -2.
Slope of parallel lines are same but the y-intercepts are different.
From the given options, the slope of the line is [tex]-\dfrac{5}{2}[/tex] only in option D and the y-intercept is -3 which is different from -2.
The line [tex]y=-\dfrac{5}{2}x-3[/tex] is parallel to the given line and parallel lines have no solution. So, the second equation of the system of equations is [tex]y=-\dfrac{5}{2}x-3[/tex].
Therefore, the correct option is D.

Answer:
[tex] PQ=4\sqrt{2} \:cm=5.66 \: cm[/tex]
Area of square PQRS[tex] = 32\: cm^2 [/tex]
Step-by-step explanation:
ABCD is a square. Points P, Q, R and S are the midpoints of sides AB, BC, CD and DA of square ABCD respectively.
Therefore,
BP = 1/2 * AB = 1/2 *8 = 4 cm
BQ = 1/2 * BC = 1/2 *8 = 4 cm
In [tex] \triangle PBQ, \: m\angle PBQ =90\degree [/tex]
Therefore, by Pythagoras theorem:
[tex] PQ=\sqrt{4^2 +4^2} [/tex]
[tex] PQ=\sqrt{2*4^2} [/tex]
[tex] PQ=4\sqrt{2} \:cm=5.66 \: cm[/tex]
Area of square PQRS[tex] =PQ^2 [/tex]
Area of square PQRS[tex] =(4\sqrt{2}) ^2 [/tex]
Area of square PQRS[tex] = 32\: cm^2 [/tex]

A function is given: f (x) = 2x + 3
What is the value of f(-2)?
Answer:
f(-2) = -1
Step-by-step explanation:
-2 is x, so replace x as -2 into the equation
f (-2) = 2(-2) + 3
f (-2) = -4 + 3
f (-2) = -1

The circumference of a circle is 8.88cm. Find the length of the diameter. Give your answer rounded to 2 DP.
Answer:
2.82
Step-by-step explanation:
The formula for the circumference of a circle is given as:
π × D
Where D represents the Diameter of the circle.
From the question:
The circumference of a circle is 8.88cm.
The Length of the Diameter is calculated as:
8.88cm = π × D
D = 8.88 cm/π
D = 2.8265917893 cm
Approximately to 2 decimal places = 2.83cm
Therefore, the length of the diameter = 2.83 cm

Answer:
- The temperature is 8 degrees below 0
- A student's class average decreases by 8 points.
Answer:
The temp is 8 degrees below 0, a student's class average decreases by 8 points
Step-by-step explanation:
a puppy gaining 8 pounds is positive
the temp is 8 degrees below 0 which is negative
the elevation of a hot air balloon is 8 meters above the ground
A student's class average decreases by 8 points = negative
The value -8 is negative and it doesn't say you have to only select one answer

Step-by-step explanation:
Charmaine has 17 cars available to rent. Let C be the number of cars she would have left after renting R of them.
Answer:
C = 17 - R
Step-by-step explanation:
In this scenario, 17 cars would be the initial starting point. While C would be the final number of cars, meaning that our equation would have to equal C. If she rents R number of cars then this number is being subtracted from the initial number of cars because Charmaine would no longer have them in his/her possession. Therefore, it is being subtracted. Using this information we can create the following equation.
C = 17 - R

Answer:
Step-by-step explanation:
6). Since, m∠JMN = 90° [Given]
And m∠JMK + m∠NMK = m∠JMN
m∠JMK = m∠JMN - m∠NMK
= 90° - 28°
= 62°
From the other figure,
m∠STR + m∠STP = 180° [Linear pair of angles]
m∠STR = 180° - m∠STP
= 180° - 118°
= 62°
Therefore, mJMK = m∠STR = 62°
And m∠JMK ≅ m∠STR
8). Since, BF is the angle bisector of ∠AFC,
∠AFB ≅ ∠BFC [By angle bisector theorem]
∠CFD ≅ ∠BFC [Given]
Therefore, ∠AFB ≅ ∠CFD [Transitive property of equality]
9). AG is the bisector of CD,
Therefore, CE ≅ DE ------- (1)
IJ is the bisector of CE,
Therefore, CK ≅ KE ---------(2)
BH is the bisector of ED,
Therefore, EF ≅ FD -------(3)
Since, CE ≅ DE [Given as (1)]
(CK + KE) ≅ (EF + FD)
2(KE) ≅ 2(EF) [Given in properties (2) and (3)]
KE ≅ EF

Answer:
25.3 pounds if all the statues way the same
Step-by-step explanation:
Answer:
25.3 lbs
Step-by-step explanation:
Assuming that all the marble statues weight the same amount, simply divide the total weight with the amount of statues:
126.5/5 = 25.3
25.3 lbs is the weight of each statue.
