Answer:
y = 2x + 6Step-by-step explanation:
[tex]M=\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{2-0}{-2-(-3)}=\dfrac21=2[/tex]
y = 2x + b passes through point (-3, 0), so:
0 = 2(-3) + b
0 = -6 + b
b = 6
Therefore the equation: y = 2x + 6

Roberto orders 13 quarts of special BBQ sauce. It costs him a total of $206.57. write an equation that can be used to find how much each quart cost. solve the equation
9514 1404 393
Answer:
13c = 206.57
Step-by-step explanation:
If c is the cost of 1 quart of sauce, then 13c is the cost of 13 quarts. We are told that is $206.57, so the equation is ...
13c = $206.57
__
You may be required to leave the dollar sign out of the equation. If you leave it in, then the answer comes with its own units (dollars).
c = $206.57/13 = $15.89

Find the one of the following sets of side lenghts could represent a right triangle
Answer:
B
Step-by-step explanation:
Using the pythagorean theorem A^2 + B^2 = C^2 the only numbers that work are those in choice B. 8 short leg, 15 long leg, 17 hypotenuse.
8^2 + 15^2 = 17^2 = 64 +225=289 = 289=289 therefor proving these set of numbers are a right triangle.
Consider △ABC. Triangle A B C is shown. Angle B C A is a right angle. The length of hypotenuse A B is 13, the length of B C is 12, and the length of A C is 5. What are the angles that make the trigonometric statements true? sin( ) = cos(B) sin(B) = cos( )
Answer:
22.62°
Step-by-step explanation:
Considering △ABC. If angle B C A is a right angle, then;
m<BCA = 90 degrees
Given also
AB = 13
BC = 12
AC = 5.
According to SOH, CAH TOA;
Sin <B = AC/AB
Cos <B = BC/AB
Substitute the given values
Sin B = 5/13
B = arcsin(5/13)
B = 22.62
Cos B = 12/13
B = arccos (12/13)
B =22.62
Hence the angles that make sinB = cosB is 22.62°
Answer:
sin(A)=cos(B)
sin(B)=cos(A)

Find the probability that a randomly selected points within a square falls in the blue shaded area (circle)
Answer:
78.8 %
Step-by-step explanation:
From the question,
Area of the square = L²
A = L²
Where L = Length of the square.
From the diagram,
L = 4 in
Therefore,
A = 4²
A = 16 in².
Also,
Area of the circle (A') = πr²
Where r = radius of the circle.
Given: r = 2 in
Therefore,
A' = 22/7(2²)
A = 12.6 in²
Hence,
The probability that a randomly selected points within a square falls in the blue shaded area (Pr) = A'/A
Pr = 12.6/16
Pr = 0.7875
Pr(%) = 78.75
Pr(%) = 78.8 %
Write the quadratic expression of the
following:
(2x + 3) (5x - 8)
Answer:
10x^2-x-24
Step-by-step explanation:
Step-by-step explanation:
First, you have to expand the expression.
[tex](2x + 3)(5x - 8) \\ = (2x)(5x) + (2x)( - 8) + (3)(5x) + (3)( - 8) \\ = 10 {x}^{2} + ( - 16x) + 15x + ( - 24) \\ = 10 {x}^{2} - 16x + 15x - 24 \\ = 10 {x}^{2} - x - 24[/tex]
is -3x+4y=8 parallel or perpendicular to -4x+3y=-6
Step-by-step explanation:
4y = 3x +8
y= 3/4x +2
3y = 4x -6
y = 4/3x -2
neither, perpendicular is negative reciprocal, and parallel m is the same. 3/4 =\ 4/3 and they are not negative reciprocals.

Find the area of each regular polygon. Round your answer to the nearest tenth if necessary
Answer:
Step-by-step explanation:
13). Area of a square = (Side)²
= (BC)²
Since, diagonals of a square bisect each other at 90°,
ΔBOC is a right triangle.
By applying Pythagoras theorem in the given triangle,
BC² = OB² + OC²
BC² = 2(OB)²
BC² = 2(7√2)²
BC = [tex]\sqrt{196}[/tex]
Area of square ABCD = (BC)²
= (√196)²
= 196 units²
14). Measure of interior angles of the regular hexagon = 120°
Area of the regular hexagon = [tex]\frac{3\sqrt{3}}{2}(\text{side})^2[/tex]
From the given picture,
m∠BAC = m∠ABC = m∠ACB = 60°
Therefore, ΔABC is an isosceles triangle.
And all sides of this triangle will be equal in measure.
AB = AC = BC = 9 units
Area of the given regular hexagon = [tex]\frac{3\sqrt{3}}{2}(9)^2[/tex]
= 210.44 square units
≈ 210.4 square units
