9x–42=5 is x = 11.

<u>Step-by-step explanation:</u>

9x- 42 = 5...

When we put x = 9

then we will get 81 - 42 =39

put x = 10 then

9(10) - 42 = 90 - 42 - 48

put x = 11

then 9(11) - 42 = 99-42 = 57

So x = 11 is the answer.

Which value of y mAkes the equation below true. 3y+8-7y=11

victus00 [196]

We have
$3y+8-7y=11$
First, we can combine like terms 3y and -7y to get -4y.
Then, we have $-4y+8=11$ We could then subtract 8 on both sides to get $-4y=3$
Finally, we isolate y completely by dividing both sides by -4, to get
$y=- \frac{3}{4}$

Answer:

$s = 54m +160$

Step-by-step explanation:

Given: The attachment

Required: Determine the equation

We start by picking any two equivalent points on the table:

$(m_1,s_1) = (2,268)$

$(m_2,s_2) = (4,376)$

Next, we determine the slope, M:

$M = \frac{s_2 - s_1}{m_2 - m_1}$

$M = \frac{376 - 268}{4-2}$

$M = \frac{108}{2}$

$M = 54$

The equation is then calculated as:

$s - s_1 = M(m - m_1)$

Where:

$M = 54$

$(m_1,s_1) = (2,268)$

So, we have:

$s - 268 = 54(m - 2)$

Open bracket

$s - 268 = 54m - 108$

Collect like terms

$s = 54m - 108 + 268$

$s = 54m +160$

Hence, the equation is: $s = 54m +160$

Beth normally cycles a total distance of 56 miles per week.

Vikki [24]

Answer:

She will cycle 85.169 miles in the third week.

(round if needed)

Step-by-step explanation:

56÷100=0.56 (this is 1%)

0.56 x 15 + 56 = 64.4 (you find 15% then add 56 (the original amount) because it's an increase of 15%)

repeat for the other 3 weeks

64.4÷100=0.644

0.644 x 15 + 64.4 = 74.06

74.06÷100=0.7406

0.7406 x 15 + 74.06 = 85.169

Jaime makes the following claim.

Sphinxa [80]

Jaime is incorrect, the angle does not depend on the radius of the circles.

<h3>Is Jaime correct?</h3>

Remember that an angle that defines an arc on a circle, does not depend on the radius of the circle.

So, if we have an angle with a measure of π/3 radians in a circle with a radius of 3 inches and an angle with a measure of π/3 radians in a circle with a radius of 6 inches, these two angles are exactly the same thing.

The radius of the circle only has an impact on the length of the arc defined by the angle.

So Jaime is clearly incorrect.

Given P(x) = 2x3 - 11x2 + 18x - 15 is divided by x – 3. Use synthetic division to find the quotient and the remainder.

katrin [286]

You can find the remainder right away by simply plugging in $x=3$ . The polynomial remainder theorem guarantees that the value of $p(3)$ is the remainder upon dividing $p(x)$ by $x-3$ , but I digress...

Synthetic division yields

3   |   2   -11   18   -15
.    |           6   -15     9
- - - - - - - - - - - - - - - - -
.    |   2     -5     3     -6

which translates to

$\dfrac{2x^3-11x^2+18x-15}{x-3}=2x^2-5x+3-\dfrac6{x-3}$

(and note that $p(3)=2(3)^3-11(3)^2+18(3)-15=-6$ , as expected)
