Answer:
we have
slope=(-5--8)/(x-7)
-3/4=3/(x-7)
-3(x-7)=3×4
-3x+21=12
21-12=3x
3x=9
x=9/3=3
Answer:
x = 3
Step-by-step explanation:
slope = [tex]\frac{y_{2} - y_{1} }{x_{2} -x_{1} }[/tex]
Using the your two points the slope = m = [tex]\frac{-8 + 5}{7-x} = \frac{-3}{4}[/tex]
[tex]\frac{-3}{7-x} =\frac{-3}{4}[/tex]
Since the numerators are equal, then the denominators must be equal.
So, 7 - x = 4
-x = -3
x = 3

Step-by-step explanation:
Four friends were born in consecutive years. The sum of their
ages is 94. What is the age of the oldest friend?
Answer:
25
Step-by-step explanation:
Since they were born on consecutive years, their ages are 4 consecutive whole numbers. Let the lowest age be x. Then the other ages are x + 1, x + 2, and x + 3.
Now we add the 4 expressions and set the sum equal to 94.
x + x + 1 + x + 2 + x + 3 = 94
4x + 6 = 94
4x = 88
x = 22

What is the slope intercept ?
PLEASE HELP ME !
Answer:
The slope is undefined.
Step-by-step explanation:
Since it is a vertical line, it does not have a y-intercept nor a slope. It runs parallel to the y-axis.
Is x ^ 2 + y ^ 2 = 6 a function?
Answer:
not a function
Step-by-step explanation:
for example
In order for an equation to represent a function any single value of x must have at most one corresponding value of y which satisfies the equation.
For x2+y2=9
XXXXif (for example) x=0
XXXXthere are two values for y (namely +3 and −3) which satisfy the equation
and therefore the equation is not a function.

A car travels 15 km in 13 minutes.
What is its average speed in km/h?
Give your answer rounded to 1 decimal place.
Answer:
69.2km
Step-by-step explanation:
15km ÷ 13 mins = 1.153km (Average speed)
1 hour = 60mins
1.153km x 60 = 69.18km (Average speed in km/h)
69.18km = 69.2km (Rounded to 1 dp)
Determine if the linear equations are parallel, perpendicular, or neither.
y = - 2x, 2y = x, 4y = 2x + 4
a
perpendicular
b
neither
c
parallel
Answer:
C. Neither
Step-by-step explanation:
The first equation is
This equation is already in the slope-intercept form;
The slope of this equation is 2.
The second equation is .
This equation is also already in the slope-intercept form.
The slope of this equation is .
Since the two slopes are not the same, the two lines are not parallel.
If these two lines are perpendicular, then the product of their slopes is -1.
But which is not equal to -1.
Therefore the two lines are also not perpendicular.
The correct choice is C.

Jose rented a truck for one day. There was a base fee of $13.50, and there was an additional charge of 8 cents for each mile driven. The
total cost, C (in dollars), for driving x miles is given by the following.
C=0.08x+13.50
What the total rental cost if Jose drove 30 miles
Answer:
2.4+13.50=15.90
Im pretty sure
Im sorry if I was wrong
Step-by-step explanation:
Answer:
15.90
Step-by-step explanation:
if Jos drove 30 miles x is equal to 30 so multiply 0.08 by 30 to get 2.40 then add the base fee to the miles driven fee and the total cost is 15.90.
C= 0.08x + 13.50
C= 0.08(30) + 13.50
C= 2.40 + 13.50
C= 15.90
2. Ajar contains 10 marbles, 6 marbles are red, and 4
marbles are blue. If 2 marbles are chosen one at a time
without replacement, what is the probability that the first
marble will be blue and the second marble will be red?
A: 3/16 B: 6/25 C: 1/8 D : 12/45
Independent or Dependent:
Final Answer:
Answer:
A
Step-by-step explanation:
Note that there are 16 total marbles. A is simply a set of sequential events. On the first, you have 10/16 chances to draw a red. Supposing this red is not replaced, the chance of drawing a second red will be 9/15; therefore, the probability of A is (10/16) * (9/15) = 0.375. Event B is translated into 2 events: Blue + (White or Red) or (White or Red) + Blue. The probabilities of each of these events, added together would be (2/16) * (14/15) + (14/16) * (2/15) = 0.2333333333; therefore, A is more probable.

Answer: The answer is A
Step-by-step explanation: I took the test on edge and got it right
The equation that is true for triangle QRS is -
Sin(100°)/3.5 = sin(S)/2.4
What is the law of sines?The law of sines can be stated as -
Sin(α)/a = Sin(β)/b = Sin(γ)/c
Given is to identify the equation that is true for triangle QRS.
Refer to the triangle as shown in the image attached. Using the law of sines, we can write -
Sin(α)/a = Sin(β)/b
Sin(100°)/3.5 = sin(S)/2.4
Therefore, the equation that is true for triangle QRS is -
Sin(100°)/3.5 = sin(S)/2.4

What is a rhombus?A rhombus can be defined as a special parallelogram as it fulfills the requirements of a parallelogram, i.e. a quadrilateral with two pairs of parallel sides. In addition to this, a rhombus has all four sides equal just like a square. That is why it is also known as a tilted square. Look at the image below to understand the relationship of rhombus shape with parallelogram and square.
Given that, Point A (2,2), Point B (3,4) and Point C (4,1)
The coordinate point for D that would make ABDC a rhombus.
So, the coordinate point for D is (5, 3).
Therefore, option C is the correct answer.

Write the equation of the line that has a slope of four and passes through the point 6,5
Answer:
4x-y=19, y=4x-19
Step-by-step explanation:
I learned a really quick way to do these in geometry.
Let's use standard form or ax+by=c.
Slope of 4: 4x - y = c.
Passes through point 6,5.
4(6) - 5 = c
c= 24-5
c=19
