The line that passes through (0 1) and (1 4) is a linear equation
The equation of the points is y = 3x + 1
How to determine the equation of the points?The points are given as:
(x,y) = (0 1) and (1 4)
Start by calculating the slope (m)
m = (y₂ - y₁)/(x₂ - x₁)
So, we have:
m = (4 - 1)/(1 - 0)
Evaluate
m = 3
The equation is then calculated as:
y = m(x - x₁) + y₁
This gives
y = 3(x - 0) + 1
Evaluate the product
y = 3x + 1
Hence, the equation of the points is y = 3x + 1

73x0.06=4.38
4.38+73=77.38
Add the sales tax to price without tax
Answer:
C. $77.38
Step-by-step explanation:
Items + tax = total
Items × .06 = tax
OR
Items × 1.06 = total
39 + 17 + 17 = 73
73 × .06 = 4.38
73 + 4.38 = 77.38

Now that you already know how to find the degree of a monomial, we move to the degree of a polynomial. A polynomial is a sum of monomials. Each monomial that is part of a polynomial is called a term of the polynomial.
To find the degree of a polynomial, find the degree of each term of the polynomial. Then the highest degree of all the monomials is the degree of the polynomial.
11.
4x³y has degree 4
3x²y² has degree 4
-y³ has degree 3
The highets degree of all terms is 4, so the degree of the polynomial is 4.
12.
a has degree 1
b has degree 1
-c² has degree 2
The degree of the polynomial is 2.
13.
The degrees of the terms are, in order, 2, 2, 2.
The degree of the polynomial is 2.
14.
The degrees of the terms are, in order, 1, 2, 1.
The degree of the polynomial is 2.
15.
The degrees of the terms are, in order, 3, 2, 1.
The degree of the polynomial is 3.
Region R is bounded by the curves y = 4x^2 and y = 4. A solid has base R, and cross sections perpendicular to the y-axis are semicircles with the diameter lying in R. The volume of this solid is
A. pi/4
B. pi/2
C. pi
D. 2pi
Each cross section has a diameter equal the horizontal distance between the two "halves" of the parabola. We have
y = 4x² ⇒ x = ±√y/2
so the diameter for some given y would be √y/2 - (-√y/2) = √y.
The volume of a cross section with thickness ∆y is then
π/2 (√y/2)² ∆y = π/8 y ∆y
The total volume of the solid would then be
[tex]\displaystyle \int_0^4 \frac\pi8 y \, dy = \frac\pi8 \times \frac12 y^2 \bigg|_{y=0}^{y=4} = \boxed{\pi}[/tex]
Estimate the perimeter and the area of the shaded figure.
A shaded composite figure is shown on a grid. The figure is made up of an isosceles triangle and an isosceles trapezoid. The triangle has a base of 6 units and height of 3 units. The trapezoid has a shorter base of 4 units, longer base of 6 units, and height of 3 units. The longer base of the trapezoid is aligned with the base of the triangle.
perimeter: about
units
area: about
square units
The shapes in the composite figures are a triangle and a trapezoid
The area of the figure is about 24 square units
The area of the figureThe dimensions of the figure are given as:
Triangle
Base = 6 unitsHeight = 3 unitsTrapezoid
Shorter base = 4 unitsLonger base = 6 unitsHeight = 3 unitsThe longer base of the trapezoid and the base of the triangle are aligned.
So, the area is:
Area = Area of triangle + Area of trapezoid
This gives
Area = 0.5 * base * height + 0.5 * (sum of bases) * height
So, we have:
Area = 0.5 * 6 * 3 + 0.5 * (4 + 6) * 3
Evaluate
Area = 24
The figure is needed to determine the perimeter
Hence, the area of the figure is about 24 square units

In how many ways could you choose 3 side dishes from a menu that offers 5 vegetable side dishes
and 3 starches if you want at least one vegetable and one starch?
Using the Fundamental Counting Theorem, it is found that there are 90 ways to choose the three side dishes.
What is the Fundamental Counting Theorem?It is a theorem that states that if there are n things, each with [tex]n_1, n_2, \cdots, n_n[/tex] ways to be done, each thing independent of the other, the number of ways they can be done is:
[tex]N = n_1 \times n_2 \times \cdots \times n_n[/tex]
In this problem:
For the vegetable, there are 5 options, hence [tex]n_1 = 5[/tex].For the starch, there are 3 options, hence [tex]n_2 = 3[/tex].The remaining dish is free, which means that there are 5 + 3 - 2 = 6 options, hence [tex]n_3 = 6[/tex].Then:
N = 5 x 3 x 6 = 90.
There are 90 ways to choose the three side dishes.

Answer:
It is 6.38 units!
Step-by-step explanation:
I took the test and it was correct.
The measure of the side length DE is 6.38 units after applying the tan ratio in the right-angle triangle option (C) 6.38 units is correct.
What is a right-angle triangle?It is a triangle in which one of the angles is 90 degrees and the other two are sharp angles. The sides of a right-angled triangle are known as the hypotenuse, perpendicular, and base.
We have a right-angle triangle given:
Triangle DEF contains right angle E. If angle D measures 50° and its opposite side measures 7.6 units,
After drawing the triangle:
Applying the tan ratio in the right-angle triangle:
tan50 = EF/DE
tan50 = 7.6/DE
DE = 7.6/tan50
DE = 6.377 ≈ 6.38 units
Thus, the measure of the side length DE is 6.38 units after applying the tan ratio in the right-angle triangle option (C) 6.38 units is correct.

Which expression is equivalent to 3(2x+4y)-y? Show your work
A. 17xy
B. 6x+12
C. 3(6xy)-y
D. 6(x+2y)-y
Hey there!
3(2x + 4y) - y
= 3(2x + 4y) - 1y
= 3(2x) + 3(4y) - 1y
= 6x + 12y - 1y
= 6x + 11y
LETS TEST OPTION D. FOR YOUR RESULT…
Option D.
6(x + 2y) - y
= 6(1x + 2y) - 1y
= 6(1x) + 6(2y) - 1y
= 6x + 12y - 1y
= 6x + 11y
6x + 11y = 6x + 11y which makes this statement TRUE ☑️
Therefore, your answer is:
Option D. 6(x + 2y) - y

Is it:
Inconsistent
Not enough information
Coincident
Consistent Independent
Answer:
(a) Inconsistent
Step-by-step explanation:
Two linear equations can be compared by putting both of them in standard form. Here, that means removing a common factor from the coefficients of the first equation.
3x -6y = -12 . . . . given first equation
x -2y = -4 . . . . . . divide by 3
Compare this to the second equation:
x -2y = -8
The constants (-4, -8) are different, so there are no values of x and y that can satisfy both equations. The equations are described as inconsistent.
Answer:
InconsistentStep-by-step explanation:
Equation 1
3x - 6y = -12Divide throughout by 3 to simpliest formx - 2y = -4Equation 2
x - 2y = -8On comparison, it is seen that the slopes are same, but the y-intercepts are different.
This means this has no solution, or the graph is inconsistent.

Answer:
Step-by-step explanation:
4x + 9y = 5
-4x + 7y = 11
Isolate y for 4x + 9y = 5
9y = 5-4x
y = (5-4x) / 9
Now plug it in this equation: -4x + 7y = 11
-4x + 7[(5-4x)/9] = 11
now just solve it.
-4x + (35 - 28x / 9) = 11
multiply both sides by 9
-36x + 35 - 28x = 99
-64x = 64
divide both sides by -64

In a pile of cards, there are four hearts, twelve clubs, and eight diamonds. How many times would we expect a diamond to be drawn in 300 trials?
The correct answer is c. 100.
Step-by-step explanation:
Number of cards in the given pile = 24
Total number of diamond cards in the pile = 8
Probability of picking up a diamond in a draw of card from the pile is given by .
There are supposed to be 300 trials.
Therefore number of times a diamond card is picked from the pile is given by 300 × = 100.
Out of 300 trials to pick a card, about 100 times we can expect to have picked up a diamond card from the pile.
