Answer:
x=9 and y=115
Step-by-step explanation:
Solve y=9x+34;y=16x−29
Steps:
I will solve your system by substitution.
y=9x+34;y=16x−29
Step: Solvey=9x+34for y:
Step: Substitute9x+34foryiny=16x−29:
y=16x−29
9x+34=16x−29
9x+34+−16x=16x−29+−16x(Add -16x to both sides)
−7x+34=−29
−7x+34+−34=−29+−34(Add -34 to both sides)
−7x=−63
−7x
−7
=
−63
−7
(Divide both sides by -7)
x=9
Step: Substitute9forxiny=9x+34:
y=9x+34
y=(9)(9)+34
y=115(Simplify both sides of the equation)

Answer:
87
Step-by-step explanation:
A^2+B^2=C^2
63^2+60^2=C^2
3969+3600=7569
Square root of 7569 is 87
Answer:
87
Step-by-step explanation:
Using Pythagoras' theorem in the right triangle.
The square on the hypotenuse (h) is equal to the sum of the squares on the other 2 sides, that is
h² = 60² + 63² = 3600 + 3969 = 7569 ( take the square root of both sides )
h = [tex]\sqrt{7569}[/tex] = 87

I need some help with this one!!!
Answer:
A
Step-by-step explanation:
The mass of an ornament is m grams.
The height of the ornament is h centimetres.
m is directly proportional to the cube of h.
m = 525 when h= 5
a) Work out an equation connecting m and h.
Given:
m is directly proportional to the cube of h.
m = 525 when h= 5.
To find:
The equation connecting m and h.
Solution:
m is directly proportional to the cube of h.
[tex]m\propto h[/tex]
[tex]m=kh[/tex] ...(i)
Where, k is the constant of proportionality.
Putting m = 525 and h= 5, we get
[tex]525=k(5)[/tex]
[tex]\dfrac{525}{5}=k[/tex]
[tex]105=k[/tex]
Putting k=105 in (i), we get
[tex]m=105h[/tex]
Therefore, the required equation is [tex]m=105h[/tex].
10. What is the equation of a line that passes through the point (4, 1) and is parallel to the line 2x - y = 42 A. y = 2x + 2 B. y = 2x - 7 C. y = -2x + 6 D. y=-2x + 9
9514 1404 393
Answer:
2x -y = 7
Step-by-step explanation:
Only the constant is different for the parallel line. It must be chosen so that the given point satisfies the equation.
2x -y = 2(4) -(1) = 7
The equation is ...
2x -y = 7

Mr. Weaver bought 192 crayons for his class. The crayons
came in packs of 24. How many packs did he buy?
Answer:
A. 24x = 192
Step-by-step explanation:
Answer:
A. 24x = 192
Step-by-step explanation:
you would have to multiply 24 x 8 in order to 192!
So yes, the correct answer would be A. 24 x = 192!
Its simple you just have to multiply how many packs x how many crayons he bought! :D

The recipe uses 1/2 cup of sugar for 1 cup of flour...how much flour should there be if there is 2 cups of sugar? *
Answer:
4 cups
Step-by-step explanation:
2 divided by 1/2 is 4 so there are 4 half cups of sugar.
Since the sugar is multiplied by 4 you have to multiply the flour by 4.
1*4=4

Answer:
length: 38 feet
width: 10 feet
area: 380 ft²
Step-by-step explanation:
The scale between the drawing and the actual studio is 2 in : 5 ft. If we divide both sides by 2, we find that the scale is 1 in : 2.5 feet.
For the first number, 15.2 inches, if we multiply it by 2.5 and change the label to "feet", we can find the real length.
15.2 * 2.5 = 38.
The length is 38 feet.
For the width, do the same thing.
4 * 2.5 = 10
The width is 10 feet.
Area is length times width. So if we plug in the numbers we just found:
38 * 10 = 380.
The area is 380 ft²

The transformation shown from Triangle P to Triangle Q is Translation.
What is a transformation?
A transformation is a general term for four specific ways to manipulate the shape and/or position of a point, a line, or geometric figure.
Given that, Triangle P is transformed to Triangle Q.
The transformation shown is a translation transformation, because in a translation transformation, all the points in the object are moved in a straight line in the same direction.
Hence, The transformation shown from Triangle P to Triangle Q is Translation.

Cos A 4/5 so the answer is d
Step-by-step explanation:
Answer:
D
Step-by-step explanation:
Remark
The tangent is described as the ratio of the side opposite the reference angle divided by the side adjacent to the reference angle.
In this case
The reference angle is B
The side opposite is AC and it has a value of 4
The side adjacent is BC and it has a value of 3
Hypotenuse
If you are finding either the sine or cosine of any angle, you need the hypotenuse.
AB^2 = 4^2 + 3^2 = 16 + 9
AB^2 = 16 + 9
AB^2 = 25
Take the square root of 25
AB = 5
Cos(A)
The cos(A) = adjacent / hypotenuse
Adjacent = AC = 4
Hypotenuse = AB = 5
Cos(A) = a/h
Cos(A) = 4/5 which is D

Answer: 5.81%
Step-by-step explanation: Delta Math
A = 17700. P = 9900. t = 10
17700 = 9900e^r(10)
17700/9900 = 9900e^10r/9900
1.7878788 = e^10r
In(1.7878788) = In(e^10r)
In(1.7878788) = 10r
In(1.7878788)/10 = 10r/10
0.058103 = r
5.8103% = r
