Answers

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:

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

Ann receives a 4% commission on her sales. Her last paycheck included $196 in commissions. Solve the formula C = 0.04s for s, where C is the amount of commission and s is the amount of sales. Then substitute to find her sales.


A.
$4,900


B.
$7.84


C.
$196.04


D.
$195.96

Answers

Answer:

A-$4,900

Step-by-step explanation:

Answer:

The answer is A. $4,900

Step-by-step explanation:

$196 in commissions  => a = 196

s = a / 0.04 = 196 / 0.04 = $4900 = Ann's sales

so the answer for Ann's sales is $4,900

If h(a)= 3a+5 and h (a) = 27 the what is the value of a?

Answers

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)

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.

Evaluate the function. f(x) = 3x² – x Find f(10)​

Answers

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
