Use elimination/linear combination to solve the following.
please help
Answer:
Step-by-step explanation:
3x + 4y = 17
5x - 4y = 7
you can thus cancel out 4y
Hence
8x = 24
Hence x = 3
Substituting’
3(3) + 4y = 17
9 + 4y = 17
Hence 17 - 9/4
= y = 2
Hope this helps
What is the range of the function shown in the graph below?
Answer:
y= -3/2X + 2
Step-by-step explanation:
we get the gradient by picking any two points from the graph( it a linear graph)
using the point:
(x,y)= (-2,5) , (4,-4)
using M= (y2-y1)/x2-x1)
we get our gradient to be -9/6 which is
-3/2
using the equation of a straight line graph which is
y-y1=m(x-x1) and the point (4,-4)
we get
y-(-4)=-3/2(x-4)
----> y+4= -3/2x + 6
make y subject of the formula to take the form
y=mx+c
we get :
y=-3/2x + 2

Answer:
96
Step-by-step explanation:
once you fill in the Blanks that are solvable, you will work your way into the answer. For example, the first column, the missing number has to be 155-76 or 79. Now you can find your answer. In the second row, “no Laptop”, you have 79 (solved above) plus 17. So your answer is 79+17 or 96.
Find the volume of each square pyramid given its slant height. Round to the nearest tenth. It looks like a normal pyramid with a slant height of 2.8 and a base of one of the triangles is 1.2.
Answer:
1.344 cubic units
Step-by-step explanation:
Given data
Base edge a= 1.2
Hieght= 2.8
The expression for the volume of a pyramid is
V= a^2h/3
substitute
V= 1.2^2* 2.8/3
V= 1.44*2.8/3
V= 4.032/3
V= 1.34cubic units

I need a list of numberlines or some other kind of explaination on how to solve this problem. I caint help you on this with out them. Sorry.
Step-by-step explanation:
Please help. Find the area of the figure below.
Answer:
81 un²
Step-by-step explanation:
9 · 7 = 63 un²
(b · h) ÷ 2
(5 · 4) ÷ 2 = 10 un²
(4 · 4) ÷ 2 = 8 un²
8 un² + 10 un² + 63 un²
81 un²
Answer:
81 un^2
Step-by-step explanation:
Find area of the rectangle. 9 x 7 = 63
Find area of the triangle. 9 x 4 = 36/2=18
63 + 18 = 81
2x + 3y = -60
2x + 3y = 120

Find the circumference of the circle to the nearest hundredth
11cm
Question: Find the circumference of the circle to the nearest hundredth
d = 11cm
Answer:
34.54 cm
Step-by-step explanation:
Applying,
P = πd...................... Equation 1
Where P = Circumference of perimeter of the circle, d = diameter of the circle, π = pie
From the question
Given: d = 11 cm
Constant: π = 3.14
Substitute these values into equation 1
P = (3.14×11)
P = 34.54 cm
Find the volume
V=bh
* B is length times width
Answer:
448 yd^3
Step-by-step explanation:
V = Bh where B is l * w
V = l*w*h
V = 8* 14* 4
=448 yd^3
Answer:
The volume of this rectangular prism is equal to [tex]448yd^{3}[/tex].
Step-by-step explanation:
From the question, we know the formula for the volume of a rectangular prism is V = Bh (where B is length times width, and "h" is the height).
Now we replace B (because we know that B is length times width) and get...
V = lwh (where "l" is the length of the prism, and "w" is the width of the prism.
Now we just substitute the values and get...
[tex]V = lwh = (14)(4)(8) = 448yd^{3}[/tex]
What is the total surface area of the rectangular prism below?
Answer:
solution given:
length[l]=3 in
breadth [b]=5in
height [h]=8in
total surface area of the rectangular prism=?
we have
total surface area of the rectangular prism
=2[lb+bh+lh]
=2[3*5+5*8+3*8]
=158 in²
total surface area of the rectangular prism is 158 in².
Answer:
158
Step-by-step explanation:
formula is 2(hL+wh+lw)
Length- 3
width- 5
height - 8
Substitue values and get answer.
2 (24+ 40+15)
2 (79)
= 158

Convert the following equation into slope intercept form y-6=2(x+4)
Answer:
y = 2x +14
Step-by-step explanation:
We need to convert the given equation into slope intercept form ,
=> y - 6 = 2(x+4)
=> y -6= 2x + 8
=> y = 2x +8+6
=> y = 2x + 14
• Hence the required answer is y = 2x + 14A jar contains 17 yellow and 12 green marbles. You randomly draw one marble from the jar then

What is the first step in solving the following equation?
28 = -12 - 4x
Answer:
4x = - 12 - 28Step-by-step explanation:
When we transpose - 4x to the LHS then it becomes positive i.e +4x
Now we transpose 28 to the RHS then it becomes negative i.e - 28
So the first step you have to is,
4x = - 12 - 28
