Answer:
5
Step-by-step explanation:
when the question asks for evaluate, always substitute the expression with the values given.
So, her x = -3 and y=4
So we find 1/2 of 2x - y
This is also half of -6-4 = -half of -10 = 5
Hope this helps,
Good Luck
Answer:
5solution,
[tex]given \\ x = - 3 \\ y = 4 \\ - \frac{1}{2} (2x - y) \\ = - \frac{1}{2} (2 \times ( - 3) - (4)) \\ = - \frac{1}{2} \times ( - 6 - 4) \\ = - \frac{1}{2} \times ( - 10) \\ = - 1 \times ( - 5) \\ = 5[/tex]
hope this helps...

A force of 76 N is applied to an area of 490 cm2. Calculate the pressure in N/m2. Give your answer to the nearest integer.
Answer:
Given
Hope it helps
Step-by-step explanation:
Pressure is the force per unit perpendicular area over which the force is applied
p=F/A
Where f is force and a is area
So P
= F/A
= 76N / 0.049m2
= (76/0.049) Nm2
= 76000/49
= 1551.02
Or 1551 N/m2

Find the area of a triangle, two sides of which are 10 cm and 16 cm and the perimeter is 38 cm.
Answer:
Step-by-step explanation:
third side=38-(10+16)=38-26=12
sides are 10 cm, 12 cm , 16 cm.
2s=10+12+16=38
s=38/2=19
area=√(s(s-a)(s-b)(s-c))
=√[19(19-10)(19-12)(19-16)]
=√[19×9×7×3]
=3√391 cm²
≈59.32 cm²

LAT QUESTION AND LAST TRY!!! WILL GIVE BRANLIEST!!!! AT LEAST TAKE A LOOK, SHARE YO SMARTNESSS!!!!!!!! PLS Is PC a perpendicular bisector of AB ? Explain your answer. LIKE 2 SENTENCES
Answer:
No, thats because a bisector means it extendes from the main branch. So thats all fine, also its supposed to be perpendicular. That means it forms a right angle. Therefore the answer is
Answer: No, Respuesta: noAnswer:
No because the line that is formed is not 90 degrees and a perpendicular line is a line that forms at a 90 degree angle.
Step-by-step explanation:
PC is not a perpendicular bisector because although it splits AB in half, it does not form a right angle with AB.

How do you use percent to convert numbers
Answer:
percent is 1/100
you just multiply the percentage value by 1/100 to find its value
If for example you are taking 20% of 500, then 20*500/100= 100 is the answer
a carpenter can make 30 chairs, 25 tables and 15 beds in a month. what proportion of the carpenter's output is bed.
Answer:
3/14
Step-by-step explanation:
Express the beds as a fraction of the total output.
Beds = 15
Total output = 30 + 25 + 15 = 70
Proportion that is beds = 15/70
15/70 = 3/14
Davita works at a shoe store. She measured the feet of nine customers and found that their shoe sizes were 4, 5, 5, 6, 7, 8, 8, 10, 10. Find the sum of the absolute deviations from the mean and the mean absolute deviation. Explain how you found the MAD.
Answer:
Sum of absolute deviation = 16
MAD = 1.78
Step-by-step explanation:
Given the following data:
X = 4, 5, 5, 6, 7, 8, 8, 10, 10
Absolute deviation from the mean means how each value in X deviates from the mean of the data without considering if the difference is positive or negative. Therefore, the absolute value is recorded and all deviations are recorded as positive.
Absolute deviation from the mean :
Mean of data (u) = (sum of data / number of observations)
( 4 + 5 + 5 + 6 + 7 + 8 + 8 + 10 + 10) / 9
= 63/9
= 7
Absolute deviation = ( x - u)
Sum of absolute deviation ;
|4-7| + |5-7| + |5-7| + |6-7| + |7-7| + |8-7| + |8-7| + |10-7| + |10-7|
3 + 2 + 2 + 1 + 0 + 1 + 1 + 3 + 3 = 16
Mean absolute deviation(MAD) ;
SUM OF ABSOLUTE DEVIATION / N
Where N = number of observations
MAD = 16/9 = 1.78
For f(x) = 2x + 1 and g(x) = x^2- 7, find (f - g)(x). ?
Answer:
(f-g)(x)=-x^(2)+2x+8
the solutions are:
x=4 or x=-2
Step-by-step explanation:
(f-g)(x)=2x+1-(x^(2)-7)
(f-g)(x)=-x^(2)+2x+1+7
(f-g)(x)=-x^(2)+2x+8
does this help or should I solve for the zeros/solutions of this quadratic equation?
then:
-x^(2)+2x+8=0
-(x^(2)-2x-8)=0
x^(2)-2x-8=0
(x-4)(x+2)=0
x=4 or x=-2
Answer:
The required answer is: -x^2+2x+8
Step-by-step explanation:
We have been given the two function:
f(x)=2x+1
And g(x)=x^2-7
We have to find (f-g)(x):
(f-g)(x)=f(x)-g(x)
(2x+1)-(x^2-7)
2x+1-x^2+7
-x^2+2x+8
Hence, the required answer is: -x^2+2x+8
what is the key vocabulary of cubic functions
Answer:
Hope it helps!
Step-by-step explanation:
The general form of a cubic function is y = ax3 + bx + cx + d where a , b, c and d are real numbers and a is not zero. We can graph cubic functions by plotting points.
A cubic function is any function of the form y = ax^3 + bx^2 + cx + d, where a, b, c, and d are constants, and a is not equal to zero, or a polynomial functions with the highest exponent equal to 3. These types of functions are extremely prevalent in applications involving volume.

No. of wooden boxes is less than 9
x< 9
No. of plastic boxes is not more than 10

what is i^84? a) -i b) i c) -1 d) 1
Answer:
D) 1
Step-by-step explanation:
When you start raising i to certain powers, you begin to notice a pattern.
[tex]i^1=i \\\\i^2=-1 \\\\i^3=-i \\\\i^4=1 \\\\i^5=i \\\\ i^6=-1 \\\\ i^7=-i \\\\i^8= 1[/tex]

Angle EMG is equal to 120 degrees. The measure of angle EMF is 60 degrees.
What is the measure of angle FMG?
Trapezoid EFGH is given. M is the midpoint of side GH. Points E and F are joined to M to form 3 equal triangles EHM, EMF and MFG.
Answer:
[tex]\angle FMG=60^{\circ}[/tex]
Step-by-step explanation:
Given: [tex]\angle EMG=120^{\circ}\,,\,\angle EMF=60^{\circ}[/tex]
To find: [tex]\angle FMG[/tex]
Solution:
A trapezoid is a quadrilateral in which one pair of opposite sides is parallel. A trapezoid in which opposite angles are supplementary is known as an isosceles trapezoid. In any isosceles trapezoid, two opposite sides are parallel, and the two other sides are equal to each other.
Consider the figure:
[tex]\angle FMG=\angle EMG-\angle EMF\\=120^{\circ}-60^{\circ}\\=60^{\circ}[/tex]

Answer:
b = 320
Step-by-step explanation:
a + b = 880
1 - 4/7 = 3/7 (restant A)
1 - 1/4 = 3/4 (restant B)
(3/7) . a = (3/4) . b
a = (7/4) . b
a + b = 880
(7/4) . b + b = 880
7b + 4b = 880 . 4
11 b = 880 . 4
b = 320
Given the functions below, find (f - g) (2).
f(x)
x2 + 3
g(x) = 4x – 3
=
Answer:
(f - g)(2) = 2
Step-by-step explanation:
Given the functions below, find (f - g) (2).
f(x) = x² + 3
g(x) = 4x – 3
(f - g)(x) = (x²+3)-(4x-3)
(f - g)(x) = x²+3-4x+3
(f - g)(x) = x²-4x+6
(f - g)(2) = (2)²-4(2)+6
(f - g)(2) = 4-8+6
(f - g)(2) = 2

In a village the number of houses and the number of flats are in the ration9:5 the number of flats and the number pf bungalows are in the ratio 10:3 there are 30 bungalows in the village. How many houses are there in the village?
Answer: 180 houses
Step-by-step explanation:
From the question, we are informed that in a village the number of houses and the number of flats are in the ratio 9:5 while the number of flats and the number of bungalows are in the ratio 10:3 and that there are 30 bungalows in the village.
Since the ratio of the number of flats and the number of bungalows are in the ratio 10:3 and there are 30 bungalows in the village, the number of flats will be:
= 10/3 × 30
= 10 × 10
= 100 flats
Since we are told that the ratio of the number of houses to the number of flats are in the ratio 9:5 and we've gotten the number of flats as 100, then the number of houses will be:
= 9/5 × 100
= 9 × 20
= 180 houses
