Find the equation of the line

slope=(y2-y1)/(x2-x1)
slope=(6-2)/(7-(-3))=4/10=2/5

slope is 2/5
y=mx+b
y=2/5x+b find b
input a point
6=2/5(7)+b
6=14/5+b
minus 14/5 from both sides
3 and 1/5=b
16/5=b
xintercept is when y=0
0=2/5x+16/5
minus 16/5 from both sides
-16/5=2/5x
times both sides by 5/2 to clear fraction
-8=x

xintercept is -8 or (-8,0)

If f(x) = 4x + 3x2 + 1, then what is the remainder when f(x)<br> is divided by X -2?
Bezzdna [24]

Answer:

remainder = 21

Step-by-step explanation:

If f(x) is divided by (x - h) then the remainder is f(h)

Here f(x) is divided by (x - 2) with h = 2 , then remainder is

f(2) = 4(2) + 3(2)² + 1 = 8 + 3(4) + 1 = 8 + 12 + 1 = 21

In a rhombus MPKN with an obtuse angle K the diagonals intersect each other at point E. The measure of one of the angles of a ∆P
ololo11 [35]
Angles PMN and MPN are also 16 because the triangles are isosceles.
The measure of the third angle (angle N) is 148 which also equal to the measure of angle K. The measure of angle PKE is 74 which half of the measure of angle N and angle K.<span />

Find the number of distinct triangles with the measurements a = 8, b = 14, and A = 30°.​
Maslowich

Answer: 2

Step-by-step explanation:

By the law of sines,

\frac{\sin B}{b}=\frac{\sin A}{a} \\ \\ \frac{\sin B}{14}=\frac{\sin 30^{\circ}}{8} \\ \\ \frac{\sin B}{14}=\frac{1}{16} \\ \\ \sin B=\frac{14}{16} \\ \\ B=\sin^{-1} \left(\frac{14}{16} \right), 180^{\circ}-\sin^{-1} \left(\frac{14}{16} \right) \\ \\ B \approx 61.04^{\circ}, 118.96^{\circ}

Since either of these values for B will form a triangle (as A+B will be less than 180 degrees), 2 triangles can be formed with these measurements.

3. Raphael bought 14 pounds of meat to make hamburgers at the Fourth of
Svetradugi [14.3K]
Raphael needs 9 packages of buns
first you need to multiply 14 by 5 to get 70 which is how many hamburgers will be made. then divide 70 by 8 to see how many packages will be needed. you get 8.75 by doing this so you have to round up to 9 to have enough.
