Answer:
Huda found the product of –3 and 9 as positive.
Step-by-step explanation:
Given the expression and result below :
Huda evaluated the expression below. Negative 3 (8 minus 5) squared minus (negative 7) = negative 3 (3) squared minus (negative 7) = negative 3 (9) minus (negative 7) = 27 minus (negative 7) = 34
-3(8 - 5)² - (-7) =
Step 1:
- 3(3)² - (-7)
Step 2:
-3(9) - (-7)
Step 3:
27 - (-7) = 34 (error in the third step)
-3(9) = - 27
Hence,
-27 - (-7) = - 27 + 7 = - 20

Solve 2x + 3y = 11 and 2x - 4y = -24 and hence find the value of 'm' for which y=mx+3.
Answer:
m=-1
Step-by-step explanation:
2x+3y=11............. (eqn 1)
2x-4y=-24...........(eqn 2)
Subtract eqn 1 from eqn 2
7y=35
y=5
Substitute for y in eqn 1
2x+3(5)=11
2x+15=11
2x=11-15
2x=-4
x=-2
y=mx+3
5=-2m+3
5-3=-2m
2=-2m
m=-1
Answer:Here,
2x+3y=11..........(i)2x-4y= -24......... (ii)Subtracting (ii) from (i),we get
2x+3y=11
- 2x+4y=24
___________
7y =35
y=5
Substituting y = 5 in (i) we get
2x+3×5=11
or,2x +15 =11
or,2x = 11- 15
or,x= -2
Now,
We know,y=mx+c
5=m ×(-2) +3
or,2=m×(-2)
or,2/-2 =m
m= -1

How long would it take for a car yo travel 200 km if it has the average speed of 55 km/HR
Answer:
3.64 hr, or 3 hr 38 min
Step-by-step explanation:
Recall that distance = (rate)(time). Thus,
time = (distance) / (rate)
Here we have:
time = (200 km) / (55 km/hr) = 3.64 hr, or 3 hr 38 min
The total distance in centimeters that a toy robot moves varies directly with the time in seconds the toy robot moves a total distance of 63 cm. In 9 seconds what is the time in seconds that the toy robot moves when the total distance is 49 cm
Answer:
Hey there!
The robot moves 63 cm in 9 seconds. Then in 1 second, it moves 7 cm.
If it goes 49 cm, it will take 7 seconds.

Find x when y=6 in the literal equation 5x+4y=39
A. 12.6
B. 15
C. 2.25
D. 3
Answer:
y=6
then,
5x+4y=39---> plug y in to the function
5x+4(6)=39
5x+ 24=39
5x= 39-24
5x= 15
x= 15/5
x= 3
So, the value of x when y=6 in that function is 3 (D)

What is the inequality 4/5__1/2
Answer:
Step-by-step explanation:
Notice that:
● 1/2 = 0.5
● 4/5 = 0.8
0.8 is greater than 0.5.
So:
● 0.8 > 0.5
● 4/5 > 1/2
Answer:
4/5 > 1/2.
Step-by-step explanation:
4/5 is greater than 1/2.

Answer:
C. 14%
Step-by-step explanation:
We know that Dallas's wage increased from $9 to $10.25.
Let's say the percent increase is x. Then we write the expression:
9 + x * 9 = 10.25
Divide by 9 from both sides:
1 + x = 10.25 / 9 ≈ 1.14
Subtract 1 from both sides:
x = 1.14 - 1 = 0.14
Since x is a percent, that means x = k/100, where k is an integer. So we have:
x = k/100 = 0.14
Multiply both sides by 100:
k = 0.14 * 100 = 14%
The answer is thus C.

The base of a triangle is 2 feet less than its height. Its area is 12 square feet. Find its base and height.
Answer:
Height of the triangle is 6 feet and base of the triangle is 4 feet.
Step-by-step explanation:
Area of a triangle is given by the formula,
Area = [tex]\frac{1}{2}(\text{Base})(\text{Height})[/tex]
Let the height of triangle = h feet
Since, base of the triangle is 2 feet less than its height then base of the triangle = (h - 2) feet
Area = [tex]\frac{1}{2}h(h-2)[/tex]
[tex]12=\frac{1}{2}h(h-2)[/tex]
h² - 2h - 24 = 0
h² - 6h + 4h - 24 = 0
h(h - 6) + 4(h - 6) = 0
(h + 4)(h - 6) = 0
h = -4, 6 feet
Since height of the triangle can not be negative, therefore, height of the triangle = 6 feet.
And base of the triangle = (h - 2) = 6 - 2
= 4 feet
Height of the triangle is 6 feet and base of the triangle is 4 feet.

if EF bisects CD, CG =5x-1, GD = 7x-13, EF = 6x-4, and GF =13, find EG
Greetings from Brasil....
As stated in the statement of the question, EF is a bisector of CD, so point G is the median point of CD, so CG = GD
5X - 1 = 7X - 13
X = 6
EF = EG + GF
6X - 4 = EG + 13 x = 6, so
6·6 - 4 = EG + 13
EG = 19(see attachment)
A line segment is also a line but the line with finite length and having fixed endpoints. The length of the line segment EG is 19 unit.
What is a line?A line is a one-dimensional shape that is straight, has no thickness, and extends in both directions indefinitely.
Given that EF bisects CD at point G, therefore, the line segment CD will be divided into two equal parts, CG and GD. Therefore, we can write,
CG = GD
5x - 1 = 7x - 13
-1 + 13 = 7x - 5x
12 = 2x
x = 12/2
x = 6
Further, the length of segment EG will be,
EG = EF - GF
= 6x - 4 - (13)
= 6x - 4 - 13
= 6x - 17
= 6(6) - 17
= 36 - 17
= 19
Hence, the length of the line segment EG is 19 unit.

Answer:
The answer is H. II and III only.
Step-by-step explanation:
A simple way to tell if a relation is a function is by taking a look at the X value, which is on the left. If the X value repeats again (ex: (0,1) (0,2) or (5,3 (5,7)) it is not a function. However, the Y value is allowed to repeat.
