Answer:
1.) -2
2.) -2
3.) -3
Step-by-step explanation:
Since we can't make a graph, we can make a table
(-5,13) and (1,1)
x y
-5 13
1 1
From 13 to 1, you subtract 12 ( y-section)
From -5 to 1, you add 6 (x-section)
Now we can do y/x
y/x = 12/6 = -2
The slope for this first one is (-2).
(-5,14) and (12,-21)
x y
-5 14
12 -21
From 14 to -21, you subtract 34
From -5 to 12, you add 17
Now we can do y/x
y/x = -34/17 = -2
The slope for this second one is (-2)
(1,1 )and (12,-21)
x y
1 12
12 -21
From 12 to 21, you subtract 33
From 1 to 12, you add 11
Now we can do y/x
y/x = -33/11 = -3
The slope for this third one is (-3)

Monique and her dad built a hang glider together. After testing the new glider for safety, the glider was ready for the first big flight. Monique jumped off a tall sand dune and traveled in a diagonal line from the top of the dune toward the ground. She flew for 137 feet and landed on level ground at a spot 105 feet horizontally from where she took off. How tall was the sand dune
answers are
a. -88 ft
b. 88 ft
c. 173 ft
d.cannot be determined
Answer:
it would have to be A I think
Pythagorean theorem states that the square of the hypotenuse of a right triangle is equal to the sum of the squares of the other two sides.
The length of the sand dune is 88 feet.
What is the Pythagorean theorem?Pythagorean theorem states that the square of the hypotenuse of a right triangle is equal to the sum of the squares of the other two sides.
We have,
Hypotenuse = 137 feet
One side length:
Horizontal length = 105 feet
Another side length = side = length of the sand dune.
Using the Pythagorean theorem we get,
137² = side² + 105²
18769 = side² + 11025
side² = 7744
side = √7744
side = 88 feet
Thus,
The length of the sand dune is 88 feet.

A plumbing company charges a $95 fee for each job, plus $65 foreach hour that the job lasts. The expression 65h + 95can be used to calculate the cost of a job in dollars, where hrepresents the number of hours the job takes to complete. Part A.What is the cost of a job that lasts 1.5 hours?
Answer:
the answer would be 160H
The cost of a job that lasts 1.5 hours is $ 192.5
What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
The charge of each job by the plumbing company = $ 95
The charge on each hour for each job = $ 65
The equation for the cost of a job is = 65h + 95
where h is the number of hours for the job
Now , to calculate the cost of job that lasts 1.5 hours ,
substitute the value of h as 1.5
And , the equation becomes
= 65h + 95
= 65 ( 1.5 ) + 95
= 97.5 + 95
= $ 192.5
Hence , the cost of a job that lasts 1.5 hours is $ 192.5

Three (3) consecutive integers is such that the largest is x. Write an expression
for the smallest.
Answer:
Consider 3 consecutive integers: (smallest) x, x+1 and x+2 (largest)
Step-by-step explanation:
Five times the smallest means 5x
Sum of the largest and five times the smallest means x+2+5x
This sum is -244 means x+2+5x=-244
Solve this equation
x+2+5x=-244
6x+2=-244
6x=-244-2
6x=-246
x=-41
So, smallest number is -41, second is -40 and largest is -39
You're answer is -39+5(-41)=244

Convert each radian measure into degrees.
4) 8pi/3
Answer:
[tex]\boxed {\boxed {\sf 480\textdegree}}[/tex]
Step-by-step explanation:
First, remember that π radians is equal to 180 degrees. Therefore, to convert from radians to degrees, multiply by 180/π.
The radian measure given is 8π/3
[tex]\frac {8 \pi}{3} * \frac{180}{\pi}[/tex]
Multiply the fractions. Multiply across the numerator, then across the denominator.
[tex]\frac{8 \pi *180}{3 * \pi}[/tex]
The pi in the numerator and denominator will cancel out.
[tex]\frac{8 *180}{3 }[/tex]
Multiply.
[tex]\frac{1440}{3}=480[/tex]
The radian measure 8π/3 is equal to 480 degrees.

30-5(5.2)30-264how do you find the axis of symmetry?
Answer:
The axis of symmetry always passes through the vertex of the parabola . The x -coordinate of the vertex is the equation of the axis of symmetry of the parabola. For a quadratic function in standard form, y=ax2+bx+c , the axis of symmetry is a vertical line x=−b2a .
Step-by-step explanation:
Answer:
x=-b/2a
Step-by-step explanation:
axis of symmetry is the line that across the vertex from a parabola(ax^2+bx+c).
The expression to find vertex is -b/2a
Thus, x=-b/2a is a vertical line that across the vertex aka the axis of symmetry.

A larger number is twelve more
than a smaller. Their sum is
84. Find the numbers.
Answer: bigger number is 48 and smaller number is 36
Step-by-step explanation:
Answer:
The smaller number ⇒ y = 36The larger number ⇒ x = y + 12 = 36 + 12 = 48Step-by-step explanation:
Let the larger number be = xLet the smaller number be = yAs the larger number is twelve more than a smaller, so
x = y + 12
As the sum of larger and smaller numbers is 84, so
x + y = 84
now substituting x = y + 12 in th equation x + y = 84
x + y = 84
(y + 12) + y = 84
2y + 12 = 84
subtract 12 from both sides
2y + 12 - 12 = 84 - 12
2y = 72
divide both sides by 2
2y/2 = 72/2
y = 36
Thus,
The smaller number ⇒ y = 36The larger number ⇒ x = y + 12 = 36 + 12 = 48solve for X round your answer to the nearest tenth

Answer:
2/3x+5=y
Step-by-step explanation:
We already know that this has to be linear and that its y-intercept is 5 ((0,5) is a point on the table). That means that the equation is
mx+5=y.
Now all we need to do is plug in some points.
3m+5=7
(Subtract 5 from both sides)
3m=2
m=2/3
