Eliminate
multiply 2nd equtaon by -1 and add to first

3x+5y=9
<u>-3x-2y=-3 +</u>
0x+3y=6

3y=6
divide by 3
y=2

sub back

3x+2y=3
3x+2(2)=3
3x+4=3
minus 4 both sides
3x=-1
divide by 3
x=-1/3

(x,y)
(-1/3,2)

The function f(x) = x2 is translated 7 units to the left and 3 units down to form the function g(x). Which represents g(x)? g(x)
Verdich [7]

Answer:

g(x)=(x+7)^2-3

Step-by-step explanation:

Given:

f(x)= x^2

Now we have to translate f(x) 7 units to the left and 3 units down to form the function g(x).

As per the rules of translation

when any parent function, in given case f(x)=x^2, is translated to 'a' units to the left then 'a' is added to the value of x. thus making f(x+a)

Also when the parent function is translated any 'a' units down then 'a' is subtracted from the value of function. thus making f(x)-a

Translating f(x), 7 units to the left

f(x+7)= (x+7)^2

Translating f(x+7), 3 units down

f(x+7)-3 = (x+7)^2-3

Hence new function g(x)=(x+7)^2-3!

Tony made 2 fruit pies. After his family ate some of each pie, 13 of one pie remained and 56 of the other pie remained. About ho
omeli [17]

Answer:

<h2>There remains 7/6 of pie.</h2>

Step-by-step explanation:

Givens

The remaining parts are 1/3 of one pie and 5/6 of the other pie.

To find how much pie is remaining, we just need to sum those fractions.

\frac{1}{3}+\frac{5}{6}=\frac{6+15}{18} =\frac{21}{18} =\frac{7}{6}

Therefore, there remains 7/6 of pie. They ate just 1/6.

The parallelogram has a base of 8 cm and corresponding height of 4 cm. The parallelogram is changed proportionally and is dilate
sukhopar [10]

Answer:

The area of the new reduced parallelogram after dilation is 8 cm^2

Step-by-step explanation:

Mathematically, the area of a parallelogram = b * h

before dilation, area of the parallelogram = 8 * 4 = 32 cm^2

After dilation by a factor of 1/2, the base of the parallelogram becomes 1/2 * 8 = 4cm while the height becomes 1/2 * 4 = 2cm

Thus, the area of the dilated parallelogram is 4 * 2 = 8 cm^2

Solve for x: -4x - 12 &lt; 12
aliina [53]

Seems like you are an imposter ;). This is Middle School math.

Anyways...

Answer:

x>6

Step-by-step explanation:

-4x-12<12

Add 12 on both sides.

-4x<24

Divide both sides by -4 to isolate x. Remember that if you are dividing by a negative, flip the sign!

x>6

Hope this helps!
