Answer:

a. 130

Step-by-step explanation:

you divide 30 by 12 and get 2.5, you then divide 325 by 2.5 and get 130.

Answer:

infinitely many solutions

Step-by-step explanation:

make both equations equal to y

so for the first one subtract 2x from both sides getting -y=-2x-1 and then multiply the entire equation by -1 and you end up with y=2x+1

and for the second one subtract 4x from both sides getting -2y=-4x-2, multiply the entire equation by -1 which gets you 2y=2x+2 and then divide the whole equation by 2 which brings you to y=2x+1

then getting rid of y and making them equal to each other gets 2x+1=2x+1 and therefore the answer is infinitely many solutions

Answer:

f(10)=290

Step-by-step explanation:

Function Evaluation

Given a function f(x) as an explicit expression, finding f(x=a) implies substituting the value of x by a in every instance it occurs.

We are given the function:

[tex]f(x)=3x^2-x[/tex]

It's required to find f(10). We replace the x for 10:

[tex]f(10)=3*10^2-10[/tex]

Operating:

[tex]f(10)=3*100-10[/tex]

[tex]f(10)=300-10[/tex]

[tex]f(10)=290[/tex]

Thus, f(10)=290

17%, 1/4, 1.7

Step-by-step explanation:

Convert each to decimals: 17% = .17, 1/4 = .25, then order from least to greatest

Hey there!

Okay, so when you get a problem like this, all you need to do in insert the given value into the function and solve.

For example:

As you can see, they state that (a) = 27, so you insert 27 in for a in the function and it will look like this:

h(27) = 3(27) + 5

Now you solve on the right side of the equal sign:

3(27) = 81 (you multiply them)

81 + 5 = 86

When you plug the value of 27 in for a in this function, your output is equal to 86.

Answer: 22/3 or 7,(3)

Solution:

h(a)=3a+5

h(a)=27

3a+5=27

3a=27-5

3a=22

a=22/3

a=7,(3)

Answer:

39

Step-by-step explanation:

Answer:

39 degrees

Step-by-step explanation:

by the triangle angle sum theorem, the 3 angles of triangles must add up to 180 degrees.

Therefore, 102 degrees + 39 degrees + x = 180 degrees

141 degrees + x = 180 degrees

x = 39 degrees

Answer:

p = 3 or p = 7

Step-by-step explanation:

Answer:

p²-7p-3p+21=0

p(p-7)-3(p-3)=0

(p-3)(p-7)=0

either

p=3

or

p=7

Answer:

8 is the answer.

Step-by-step explanation:

Think of 7 positive things and 8 negative things.

O O O O O O O

P P P P P P P P

7 of the positive things will cancel out 7 of the 8 negative things, leaving behind 1 negative things.

Step-by-step explanation:

Answer:

[tex]16^{3/2}[/tex] = [tex]\sqrt[]{16^{3} }[/tex]

Step-by-step explanation:

All you need to do to find which is equivilant is put [tex]16^{3/2}[/tex] into radical form.

To do this you first need to know that the denominator of the fractional exponent will become the root of the radical, and the numerator will become the power.

So the 3 will be the power, now just rewrite it as [tex]\sqrt[]{16^{3} }[/tex].

If you don't know what the root or power is:

[tex]\sqrt[n]{x^{m} }[/tex] the n represents the root, and the m represents the power.
