Find the zeros 7x(x-11)-2(x-11)=0
(x-11)(7x-2)=0
x=11 or x=2/7
Answer:
x = [tex]\frac{2}{7}[/tex], x = 11
Step-by-step explanation:
Given
7x(x - 11) - 2(x - 11) = 0 ← factor out (x - 11) from each term
(x - 11)(7x - 2) = 0
Equate each factor to zero and solve for x
x - 11 = 0 ⇒ x = 11
7x - 2 = 0 ⇒ 7x = 2 ⇒ x = [tex]\frac{2}{7}[/tex]

When the angle of elevation of the sun is 78 degrees, a tree casts a 13 foot shadow. How tall is the tree?
Answer: 61.16 ft
Step-by-step explanation:
We can think in this situation as a triangle rectangle.
where:
The height of the tree is one cathetus
The shadow of the tree is the other cathetus.
We know that the angle of elevation of the sun is 78°, an angle of elevation is measured from the ground, then the adjacent cathetus to this angle is the shadow of the tree. And the opposite cathetus will be the height of the tree.
Now we can remember the relationship:
Tg(A) = (opposite cathetus)/(adjacent cathetus)
Where:
A = 78°
Adjacent cathetus = 13ft
opposite cathetus = height of the tree = H
Then we have the equation:
Tg(78°) = H/13ft
Tg(78°)*13ft = H = 61.16 ft

You bought 3/4 pound of fudge for 6.75. Write and solve an equation to find the cost of the fudge per pound.
Given:
You bought [tex]\dfrac{3}{4}[/tex] pound of fudge for 6.75.
To find:
The equation and solve the equation to find the cost of the fudge per pound.
Solution:
Let x be the cost of the fudge per pound.
You bought [tex]\dfrac{3}{4}[/tex] pound of fudge for 6.75.
[tex]\dfrac{3}{4}x=6.75[/tex]
[tex]3x=6.75\times 4[/tex]

Translate the following verbal expression into an algebraic expression.
“Three times the sum of a number and seven”
Answer:
3 * (x + 7)
Step-by-step explanation:
Mark number as x
Then the sum of a number and seven is x + 7
Three times x + 7 can be written as
3 * (x + 7)
Parentheses mean that we first add x and 7 and then multiply their sum by 3
Alternatively you can write it as 3x + 21, since
3 * (x + 7) = 3 * x + 3 * 7 = 3x + 21

If at 9 a.m. the temperature was below freezing, which means below 0 degrees Celsius, then the point would be plotted in the third quadrant (III).
What is coordinate plane?The coordinate plane has four quadrants, which are numbered using Roman numerals I, II, III, and IV, and they are separated by the x-axis and y-axis.
In this case, the temperature was below freezing at 9 a.m., which means it was less than 0 degrees Celsius.
The point would be plotted in the third quadrant (III), where the x-value is negative and the y-value is negative, because the x-axis represents the time in hours before noon and the temperature is negative.
At 11 a.m., however, the temperature was 10 degrees Celsius, which is a positive value.
Thus, the point would be plotted in the first quadrant (I), where both the x-value and the y-value are positive, because the x-axis represents the time in hours before noon and the temperature is positive.

A sno-cone machine priced at $139 is on sale for 20% off. The sales tax rate is 6.75%. What is the price of the sno-cone machine after the discount and sales tax?
Answer:
$127.03
Step-by-step explanation:
A snow cone machine price at $139 is on after for 20 off.
The price after discount=139-20=$199
The sale tax rate 6.75%
Price with sales tax=199+(6.75%×199)
=199+(0.0675×199)
= 199+8.03
=$127.03

Answer:
See answer below
Step-by-step explanation:
In this case, we can assume that this function follows a linear function. In this case, the general expression would be:
y = a + bx
Where:
a: Y intercept
b: slope of the function
To get the slope we need to apply the following expression:
b = y₂ - y₁ / x₂ - x₁
We already have two points, (80,0) and (40,16) from here, we can determine the slope:
b = 16 - 0 / 40 - 80
b = -16/40
b = -2/5
Now that we know the slope, we can determine the y-intercept if it have:
a = y - bx
Using any point, we can calculate it:
a = 0 - (-2/5*80)
a = 0 + 160/5
a = 32
With these two values, we can write the function:
h(x) = 32 - 2/5xHope it helps
