Help me pleaseeee ???
Leokris [45]
There's only one solution...the one you get when you divide both sides by 22 to solve for x.  902/22 = 41.  That exponent on the x, the one you don't see, is a "1" which tells us that there is only 1 solution to this problem.  If your x is squared, then you have 2 solutions; if it's cubed, you have 3, etc.

A straight line y = mx + c is parallel to y = 3x +2
Anna11 [10]

Answer:

m = 3 and c = - 1

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = 3x + 2 ← is in slope- intercept form

with m = 3

• Parallel lines have equal slopes, thus

y = 3x + c ← is the partial equation of the parallel line

To find c substitute (1, 2) into the partial equation

2 = 3 + c ⇒ c = 2 - 3 = - 1

y = 3x - 1 ← equation of parallel line

with m = 3 and c = - 1

For some reason it says square but please help! I need to know step by step what to do.
quester [9]

Answer:

8.06 inches

Step-by-step explanation:

The diagram shows a rectangle with width of 4 inches and area of 28 square inches.

Use area formula:

A_{\text{rectangle}}=\text{Width}\times \text{Length}

So,

28=4\times \text{Length}\Rightarrow \text{Length}=\dfrac{28}{4}=7\ \text{inches}

By the Pythagorean theorem,

\text{Diagonal}^2=\text{Width}^2+\text{Length}^2\\ \\\text{Diagonal}^2=4^2+7^2\\ \\\text{Diagonal}^2=16+49\\ \\\text{Diagonal}^2=65\\ \\\text{Diagonal}=\sqrt{65}\approx 8.06\ \text{inches}
