-7 - -3(x+3)>5 how do I work this problem

Mathematics
1 answer:
charle [14.2K]3 years ago
5 0

Answer:

x > 1

Step-by-step explanation:

It's actually a pretty simple algebra problem, you can pretend the > is an = for the most part.  The only difference is if you ever multiply or divide by a negative you flip the direction

-7 + 3(x+3)>5 (as long as that double minus sign was accurate)

-7 + 3x + 9 > 5

2 + 3x >5

3x > 3

x > 1

Now, like I mentioned if you divide or multiply by a negative the inequality flips.  so say you multiply by -1 on both sides you will get -x < -2.  I just want to make sure you remember that because it can be hard to remember.

How would you describe the difference between the graphs of f(x) = x^2 +4 and<br> g(y) - y^2 +4?
s2008m [1.1K]

Answer:

Step-by-step explanation:

The function f(x)=x^2+4 is a positive upwards opening parabola with the vertex at (0, 4), whereas

the function g(y)=y^2+4 is a positive rightwards opening parabola (sideways parabola) with the vertex at (4, 0). This means that answer to this is that g(y) is reflected over the x axis whereas f(x) is reflected over the y axis.

PLEASE HELP!!!<br> Solve for X...<br> Cos30=x/8<br> Answer MUST be in radical form. NO DECIMALS.
Ivenika [448]

cos(30)=x/8

Rewrite the equation as

x/8=cos(30)

Multiply both sides of the equation by

8

.

8

⋅

x/8=8⋅cos(30)

Simplify both sides of the equation.

Tap for more steps...

x=4√3

The result can be shown in multiple forms.

Exact Form:

x=4√3

Decimal Form:

x=6.9282032

Bianca needs to paint a logo made using two right triangles. The dimensions of the logo are shown below. What is the difference
Rina8888 [55]
Correct Answer: 4.5 cm²

Two triangles of different sizes make up the logo. We are to find the difference in the areas of these triangle. Smaller triangle has a base of 2 cm and height 6 cm. Larger triangle has the base of 3 cm and height 7 cm.

Area of the triangle = \frac{1}{2} x Base x Height

So,
Area of smaller triangle = \frac{1}{2} *(2)(6)=6 cm²
Area of larger triangle = \frac{1}{2} *(3)(7)=10.5 cm²

The difference in the areas of triangles = 10.5 - 6 = 4.5 cm²<span />
