Step-by-step explanation:
8х + 5у = -7
— 7х + бу = — 4
Answer: x = -0.2651 and y = -0.9759
Step-by-step explanation:
Solution by substitution method
8x+5y= -7
-7x+6y= -4 = 7x-6y=4
Suppose,
8x+5y=-7→(1)
7x-6y=4→(2)
Taking equation (1), we have
8x+5y= -7
⇒8x= -5y -7
⇒x= -5y-7 / 8 →(3)
Putting x= -5y-7 / 8
in equation (2), we get 7x-6y=4
7(-5y-7/8)-6y=4
⇒-35y-49-48y=32
⇒-83y-49=32
⇒-83y=32+49
⇒-83y=81
⇒y= 81 / -83
⇒y= -0.9759→(4)
Now, Putting y= -0.9759 in equation (3), we get
x= -5y-7
x= -5(-0.9759)-7/8
⇒x= 4.8795-7/8
⇒x= -2.1205/8
⇒x= -0.2651
∴x= -0.2651 and y = -0.9759

if a ball falls off a cliff that is 20 meters tall and down to the bottom of a pond that is 13meters deep, what is the total distance traveled by the ball? *
7 meters
20 meters
33 meters
13 meters
Answer:
Let H be height of a cliff
h depth of the pond
Total distance traveled (S)= H+h
S=20+13
S=33m
Step-by-step explanation:
Answer:
33 meters is the total distance
Step-by-step explanation:
the distance between the two points is 33 it does not matter if the distance is off the cliff or underwater it's still 20+13=33

8p<-3
Answer:
Step-by-step explanation:
8p < -3
You must isolate P
In order to do this, you need to get rid of anything on that side.
P is being multiplied by 8, so you must do the inverse in order to get rid of it.
The opposite of multiplying is dividing, so divide BOTH sides by 8.
8p / 8 < -3 / 8
You are left with:
p < -3 / 8
That is the answer
Find each function value f(-4) if f(x) = -5x - 3
Answer: f(-4) = 17
Step-by-step explanation: Substitute (-4) for x.
f(-4) = -5(-4) - 3f(-4) = 20 - 3f(-4) = 17What's the intercepts of the line 4x-3y=17
X[__,__]
Y[__,__]
Answer: REMEMBER (X, Y)
x(4 1/4, 0)
y(0, -5 2)
Step-by-step explanation:
Find the x-intercept
To find x intercept subtract y equals 0
4 x - 3 × 0 = 17
Any equation multiplied by 0 equals 0
4x - 0 = 17
When adding or subtracting zero quality does not change
4x = 17
Divide both sides of the equation by 4
x = 17/4
Solution
X = 17/4
Alternate form
X = 4 1 / 4, x = 4.25
Find y-intercept
To find y intercepts subtract x equals 0
4 × 0 - 3y = 17
Solve the equation for y
Y = -17 / 3
Solution
y = -17 / 3
Alternate form
y = -5 2 / 3, y = -5.6

Answer: 140

Please help me I have to get it done by 8 am!!!
Answer:
x = 20
Step-by-step explanation:
Here, we want to get the value of x
To get the value of x, we need to know the kind of relationship that exists between the two given angles
Both angles lie on a straight line and that means they are supplementary
What this mean is that they add up to 180
(5x-7) + (3x + 27) = 180
5x -7 + 3x + 27 = 180
5x + 3x -7 + 27 = 180
8x + 20 = 180
8x = 180-20
8x = 160
x = 160/8
x = 20

the giraffe is the worlds tallest land mammal. if the scale is 1/2 inch represents 5 feet . the giraffe is 20 feet tall . how many inches is the giraffe?
Answer:
The giraffe will be 2 inches
Step-by-step explanation:
If we know that if the scale is 1/2 inch to 5 feet we simply just have to divide the height of the giraffe by 5 feet and then multiply it by 1/2 inches. So we do...
20feet / 5 feet x 1/2 inches = 4 x 1/2inches = 2 inches

5.) g(x) = -4x + 2. Find x when g(x) = 22.
I'm on a timed test and I wasn't able to study because of personal reasons
Answer:
x = -5
Step-by-step explanation:
If g(x) = 22 and g(x) = -4x + 2, then -4x + 2 = 22.
Isolate x.
-4x = 22 - 2
= -4x = 20
= x = 20 ÷ -4

Anna has a box of chocolates. In the box there are milk, plain and white chocolates in the ratio 4:3:2. Anna doesn't like white chocolates. Work out the probability that she will pick a chocolate that is not white? *
Complete question :
Anna has a box of chocolates. In the box there are milk, plain and white chocolates in the ratio 4:3:2. The box contains 72 chocolates altogether. Anna doesn't like white chocolates. Work out the probability that she will pick a chocolate that is not white?
Answer:
7 / 9
Step-by-step explanation:
Calculate the number of each type of chocolate :
Milk : plain : white = 4 : 3 : 2
Total ratio = (4 +3 +2) = 9
Milk = (4/9) * 72 = 32
Plain = (3/9) * 72 = 24
White = (2/9) * 72 = 16
Probability of picking a chocolate that is not white :
Number of non-white :
(plain + milk) = (24 + 32) = 56
Probability = (required outcome / Total possible outcomes)
P(not white chocolate) = (number of non-white / total number of chocolates)
= 56 / 72
= 7 / 9
Sasha hikes into a canyon. She takes a break at the rest stations every 2/3 of a mile.
If she started at sea level and has hiked down to the fourth rest station, what is Sasha’s elevation now?
Select all that apply.
Answer:
The correct options are;
A. [tex]-\dfrac{8}{3} \ miles[/tex]
D. [tex]2\dfrac{2}{3} \ mile[/tex] below sea level
Step-by-step explanation:
The given parameters are;
The distance Sasha travels down before a stop = -2/3 mile
The level at which Sasha starts to hike into the canyon = Sea level
Therefore, we have;
Her elevation at the fourth rest station = 4 × -2/3 mile = -8/3 miles
Therefore, we have;
-8/3 mile = [tex]2\dfrac{2}{3} \ mile[/tex] below sea level
Therefore, the correct options are;
-8/3 mile and [tex]2\dfrac{2}{3} \ mile[/tex] below sea level.
