Answer:

(4 * x) - 15

Step-by-step explanation:

"15 fewer" means "subtract 15" or - 15

"the product of 4 and a number":

Product is another word for "multiply".

A number is generally set as a variable, "x".

The product of 4 and a number means 4 * x, or 4x.

Set the equation:

4x - 15 is your answer.

Find the measure of angleq, the smallest angle in a triangle whose sides have lengths 4, 5, and 6. round the measure to the near

Pavlova-9 [17]

The measure of the ∠Q = 41°

By law of cosines:

a law in trigonometry: the square of a side of a plane triangle equals the sum of the squares of the remaining sides minus twice the product of those sides and the cosine of the angle between them.

Which can we stated as:

${q}^2 = {p}^2 + {r}^2 - 2prcos(Q)\\{4}^2 = {6}^2 + {5}^2 - 2*6*5*cos(Q)\\\\$

solving equation using normal algebra:

60cos(Q) = 36 + 25 - 16

60 cos(Q) = 45

cos(Q) = 45/60

cos(Q) = 3/4

$Q = {cos}^{-1} (\frac{3}{4})\\$

Thus, Q = 41°

Hence, the measure of the smallest angle in a triangle whose sides have lengths 4, 5, and 6. ∠Q is 41°.

Solve for x. 4/x−3+2/x^2−9=1/x+3

Levart [38]

Answer:

$x=-\frac{17}{3}$

Step-by-step explanation:

we have

$\frac{4}{x-3}+\frac{2}{x^{2}-9}=\frac{1}{x+3}$

Solve for x

Applying difference of squares in the denominator of the second term in the left side

$\frac{4}{x-3}+\frac{2}{(x+3)(x-3)}=\frac{1}{x+3}$

Multiply both sides by (x+3)(x-3)

$4(x+3)+2=(x-3)$

Apply the distributive property in the left side

$4x+12+2=x-3$

Combine like terms left side

$4x+14=x-3$

Group terms

$4x-x=-3-14$

$3x=-17$

Divide by 3 both sides

$x=-\frac{17}{3}$

An equation is shown below with a missing value.

natali 33 [55]

Answer:

x=4

Step-by-step explanation: Let's solve your equation step-by-step.

3x+2=14

Step 1: Subtract 2 from both sides.

3x+2−2=14−2

3x=12

Step 2: Divide both sides by 3.

x=4

Graph the solution set for this inequality: 4x - 2y > 8

mr Goodwill [35]

Answer:

x-intercept: 2 y-intercept= -4

Step-by-step explanation:

First, change the given equation 4x-2y>8 to slope-intercept form, which is y=mx+b. We do this by solving for y.

4x-2y>8. Subtract 4x from each side

-2y> -4x+8. Divide by -2. Don't forget to switch the sign!

y< 2x-4 is our equation in slope-intercept form.

Now, we can graph it. We know the slope (m)= 2 and the y-intercept= -4. Start at -4 and move up two, over one, making points until you can form a line. We can see from the graph that when x=0, (0, -4) y= -4. When y=0, (2, 0), x=2. These are our intercepts of the graph!

Hope this helps!
