PLEASE HELP!

Mathematics

There are various ways to solve this. I will solve by elimination which seems easier:
I multiply the top equation by 1/2 to get 1/4y so I can eliminate y:
-3x/8 + 1y/4 = -1 Now add the second equation:
1x/5 - 1y/4 = -6 This gives:
------------------------------------
-3x/8 + 1x/5 = -7 Get a common denominator:
-15x/40 + 8x/40 = -7 Now add fractions:
-7x/40 = -7 Multiply by the reciprocal(-40/7):
x = 7 × 40 / 7 Simplify:
x = 40.
Now plug in 40 for x in one of the equations and solve for y (2nd equation looks easier):
1(40)/5 - 1y/4 = -6
8 - y/4 = -6 subtract 8
-y/4 = -14 multiply by 4
-y = -56
y = 56.

So we got x=40 and y=(56) new lets check!
-3(40)/4 + (56)/2 = -2
-3(10) + 28 = -2
-30 + 28 = -2
-2 = -2.

The graph of the function f(x)=|3x| is translated 4 units up.
siniylev [52]
Translating a graph upwards just means adding or subtracting a value from the initial function.

So to push a graph up, you just add (+) the number of units onto the original function.

How do i find the perimeter and area?
Contact [7]

First, we need to find the base. To do so, we will need to use the Pythagorean Theorem on one of the smaller triangles to solve for its unknown side. Then, we can double the base of the one to find the base of the whole.

Pythagorean Theorem: a^2 + b^2 = c^2

(12)^2 + b^2 = (16)^2

144 + b^2 = 256

b^2 = 112

b = \sqrt{112}

b = 4\sqrt{7}

total base = 2 x 4\sqrt{7} = 8\sqrt{7}

Second, we can find the area. The formula for the area of a triangle is A = 1/2 x base x height.

A = 1/2 x 8\sqrt{7} x 12

A = 4\sqrt{7} x 12

A = 48\sqrt{7} units^2

Third, we can find the perimeter. The perimeter is the sum of all of the exterior sides.

P = 16 + 16 + 8\sqrt{7}

P = 32 + 8\sqrt{7} units

Hope this helps!! :)

Andrea bought 12 bagels and 10 muffins at the bakery of these items 2/3of the bagels were Multigrain and3/5of the muffins were b
nevsk [136]
Hi there!

If Andrea bought 12 bagels and 2/3 were multigrain we can determine what the total amount of bagels that are multigrain by finding a common denominator. We can do this by multiplying 2/3 * 4 which gets us the common denominator we need.

2/3 * 4 <--- Equation
8/12 <--- Simplified from step 1.

Therefore 8 out of the 12 bagels Andrea bought were multigrain!
