Answer: The equation for a line is y = mx + b. B is the y-intercept (where x=0). If your B value is 6, then your y-intercept is (0,6). This is the same with negatives, if you have a negative B value, then the y-intercept is below the x-axis. For example, a B value of -6 would mean that the line crosses the y-axis at (0,-6).

M is your slope. Your slope can be determined by rise/run (how far your line goes up between each point/how far horizontally your line travels between each point). A slope of 2 would mean that the y-values on my line are double the x-values on my line. If a point on the line was (1,2), we could find the slope value by taking 2 and dividing it by 1.

If I had y = 6x+2, my slope would be 6, and my y-intercept would be 2.

Feel free to ask anything is still a little confusing :D

danny has a trianglular pyramid all triangles are conguent what is the surface area?the height is 6in and the width is 5in

Gre4nikov [31]

Answer: The answer is 60 square inches.

Step-by-step explanation: Given that Danny has a triangular pyramid where all the four triangles are congruent. The height and base of one triangle are 6 inches and 5 inches respectively. We are to find the surface area of the pyramid.

The area of one triangle is given by

$A=\dfrac{1}{2}\times\textup{base}\times\textup{height}=\dfrac{1}{2}\times 5\times 6=15~\textup{sq. inches}.$

Since the pyramid consists of four congruent triangles, so the surface area of the pyramid will be

$S=4\times A=4\times 15=60~\textup{sq. inches}.$

Thus, the answer is 60 sq. inches.

NARA [144]

Answer:

PB = 1.8

Step-by-step explanation:

PQ = 8 cm, BC = 10 cm and AB = 9 cm

∆ABC is similar to ∆APQ.

Therefore:

$\frac{AB}{AP} = \frac{BC}{PQ}$

Plug in the values

$\frac{9}{AP} = \frac{10}{8}$

Cross multiply

AP × 10 = 8 × 9

AP × 10 = 72

Divide both sides by 10

AP = 7.2

PB = AB - AP

PB = 9 - 7.2

PB = 1.8

Can someone help me pls

FrozenT [24]

There are 4 lateral faces that are triangles. Each triangle is: A = $\frac{b x h}{2}$
A = $\frac{16 x 22}{2}$
   = 176

There is one base that is a square. A = L x W
A = 16 x 16
   = 256

Surface area = 256 + 4(176)
                     = 256 + 704
                     = 960

Answer: B
