Answer:

y = 7/8x + 1

Step-by-step explanation:

According to y = mx + b, whereas b is the y-intercept

so if b is positive, b has to be larger than 0

A non-proportional graph is a straight line that does not go through the origin so

The #1 and #4 are wrong because they are proportional

The #2 and #4 are wrong because they have negative y-intercept

Which relationship describes angles 1 and 2?

stiks02 [169]

They are vertical angles and here’s why.

Vertical angles are a pair of opposite angles formed by intersecting lines.

Supplementary angles are two angles that equal 180 when added together.

Adjacent angles are two angles that have a common side and a common vertex.

Complementary angles are two angles that add up to 90 degrees.

Hope this helped!

Licemer1 [7]

So according to the problem, the tax should be calculated using the bill.

So 5.5% equals to 0.055.

Then multiply 0.055 and 74.98.

Thus resulting in 4.1239 and when rounded, the answer should be 4.12, C

Solve the following exponential equations.<br> 10^(3x−5) = 7^x

zalisa [80]

Answer:

x = 2.3202

Step-by-step explanation:

Given equation:

$10^{(3x-5)} = 7^x$

on taking log both sides, we get

$\log(10^{(3x-5))} =\log(7^x)$

now,

using the property of log function

log(aᵇ) = b × log(a)

therefore,

we get

(3x-5)log(10) = xlog(7)

now,

log(10) = 1

and

log(7) = 0.84509

thus,

( 3x - 5 ) × 1 = 0.84509x

3x - 0.84509x - 5 = 0

2.15491x = 5

x = 2.3202

-2(3x-1)<8 on a number line

Veronika [31]

Answer:

Checkout the image below the explanation.

Step-by-step explanation:

1. First, let's solve the inequality.

Step 1: Simplify both sides of the inequality.

$-6x + 2 < 8$

Step 2: Subtract 2 from both sides.

$-6x + 2 - 2 < 8 - 2$
$-6x < 6$

Step 3: Divide both sides by -6 and flip the sign.

$\frac{-6x}{-6} < \frac{6}{-6}$
$x > -1$

2. Now that we solved the inequality and got x > -1, that means that all values of x are more than -1. It can be represented on the number-line as this:
