Answer:

y = 3x + 2; y = -x + 4

Step-by-step explanation:

Slope intercept form is in y = mx + b, where m is the slope and b is the y-intercept. In the first image, 2 is the y-intercept and 3 is the slope, yielding the equation y = 3x + 2.

For the second, 4 is the y-intercept and -1 is the slope, so the answer to the second image is y = -x + 4.

How do i solve this? ASAP!

Answer:

Similar triangles states the length of the corresponding sides are in proportion.

In a given similar triangles:

Labelled the diagram:

Triangle BAC and triangle DAC are similar.

then;

Corresponding sides:

$\frac{AB}{AD} = \frac{BC}{DC}$

AB = x units , BC = 5 units, AD = 15 units and DC = BD-BC = 8-5 = 3 units

$\frac{x}{15} = \frac{5}{3}$

By cross multiply we get;

$3x = 15 \cdot 5$

Simplify:

$3x = 75$

Divide both sides by 3 we get;

$\frac{3x}{3}=\frac{75}{3}$

Simplify:

x = 25 units

Therefore, the value of x is 25 units.

Here's what I got.

Column C, starting from the top and going down: $12.33, $13.00, $10.50, $10.00, $6.00, $8.00, $4.25, $10.50, $11.50, and $8.50

Column F, Starting from the top and going down: $4,650, $4,650, $4,650, $4,600, $4,600, $4,600, $5,000, $5,000, $4,625, and $4,625.

I don't really understand column G yet, so that's all I have. Hope it helped a little bit.

Use the graph below to answer the following question:

worty [1.4K]

9514 1404 393

Answer:

B. -1

Step-by-step explanation:

The relevant points on the graph are (1, 3) and (4, 0). The average rate of change can be found using the slope formula ...

m = (y2 -y1)/(x2 -x1)

m = (0 -3)/(4 -1) = -3/3 = -1

The average rate of change from x = 1 to x = 4 is -1.

andre [41]

Answer:

A) $T=\frac{-20}{4}$

B) T = -5 °C

Step-by-step explanation:

A) Let T be the change in temperature of the week. T is determined as the total temperature change (-20°C) divided by the number of weeks that have passed (4 weeks). The expression is:

$T=\frac{-20}{4}$

B) In order to simplify the expression, simply perform the division.

$T=\frac{-20}{4}\\T=-5^oC$

This means that the temperature has dropped by 5 degrees each week.
