-5x + 9 = -3x + 1 solve the equation
Helen [10]

Answer:

x=4

Step-by-step explanation:

Step 1: Add 3x to both sides.

−5x+9+3x=−3x+1+3x

−2x+9=1

Step 2: Subtract 9 from both sides.

−2x+9−9=1−9

−2x=−8

Step 3: Divide both sides by -2.

−2x/−2=−8/−2

11, 14, 17,...<br> Find the 42nd term.
Ainat [17]

Answer:

134

Step-by-step explanation:

This sequence is arithmetic because it's going up by sane number, 3. Hence, it also linear for the same reason. The equation is y=3x+(0th term). The 0th term is the one before the 1st term, 11, which would be 8.

So the equation to finc any xth term is y=3x+8.

Example, first term is 3(1)+8=11.

Example, second term is 3(2)+8=14.

Example, third term is 3(3)+8=17.

The 42nd term is 3(42)+8=126+8=134.

2. The area for a circle is as follows:
A = π{r^2}

The radius of the circle is 4 in, so we plug that into the equation.

A = π (4{in.^2})

4 {in.^2} = (4 in.)(4 in.) = 16 {in.^2}

A = 16π {in.^2}

This is the area for the whole pizza, so divide that by 2 to get the area of the pepperoni

a) 8π {in.^2}

For the bacon, we can just divide the value we already have by 2, since it is half the area of the pepperoni

b) 4π {in.^2}

3. This question is asking for the circumference, whose equation is as follows:
C = 2 π r

We can use the area formula, A = π{r^2} to find the radius of this circle
36π = π{r^2}

Divide both sides by π:
36 = {r^2}

Square root both sides:
r = 6 in.

Plug in this value to the circumference formula, C = 2 π r
C = (2)(π)(6 in.)

Your final answer is:
C = 12π in.
