Point D: (-5,-3)
Step-by-step explanation:
PLEASE HELP ME :(. Look at this system of equations.
X - 8y = -3
5x - 2y = 4
What value of a will make this system have the same solution?
ax = -19
5x - 2y = 4
9514 1404 393
Answer:
a = -19
Step-by-step explanation:
In the first set of equations, subtract 4 times the second equation from the first.
(x -8y) -4(5x -2y) = (-3) -4(4)
-19x = -19 . . . . simplify
Comparing this to the equation ...
ax = -19
we see that they will have the same solution when a = -19.

A box has 14 identical balls, three of which are blue, then two balls are drawn at random from the box, one after the other without replacement. Calculate the probability that
(i) the two balls are both blue
(ii) Atleast one ball drawn is blue.
Answer:
3/91 ; 36/91
Step-by-step explanation:
1) favourable event/ total possibilities * favourable event/ new total possibilities
3/14 * 2/13 = 3/91
2) it is simplier calculate the probability of the opposite event (no balls are blue)
11/14 * 10/13 = 55/91
91 - 55 = 36
final answer 36/91

25
625
5
10
Answer:
C. 5Step-by-step explanation:
The area is the product of two dimensions.
If the ratio of sides is k, then the ratio of areas is k²
We have:
k² = 200/8k² = 25k = √25k = 5Correct choice is C

You lean a 6 foot ladder against the wall. If the base is 4 feet from the wall, what angle does the ladder make with the ground? Round to the nearest tenth.
Answer:
48.19
Step-by-step explanation:
angle we are trying to find is x
cos(x) = opposite/hypotenuse = 4/6 = 2/3
cos^-1(x) = 48.19
Which Trig ratio should be used to find the missing side?

D) 22*5*7
Step-by-step explanation:
This one is best done by doing a pre factor.
140 = 14 * 10 Now all you need do is factor those two numbers.
140 = 7*2 * 5 * 2
Rearranging this you get 2 * 2 * 5 *7

Answer:
x=14.0°
Step-by-step explanation:
x= angle of slope
[tex]tanx=\frac{12.0ft}{98.0ft} =0.2500[/tex]
[tex]x=tan^{-1} (0.2500)[/tex]
[tex]x=14.0[/tex]
so, the angle of slope is 14.0°

using appropriate properties find 9/16×4/12+9/16×-5/9
Answer:
-1/8
Step-by-step explanation:
Given 9/16×4/12+9/16×-5/9
Using the PEMDAS rule;
Multiplication first
(9/16×4/12)+(9/16×-5/9)
= 3/4 * 1/4 + -5/16
= 3/16 - 5/16
= (3-5)/16
= -2/16
= -1/8
Hence the required answer is -1/8

The print on the package of -watt General Electric soft-white light-bulbs says that these bulbs have an average life of hours. Assume that the lives of all such bulbs have a normal distribution with a mean of hours and a standard deviation of hours. Find the probability that the mean life of a random sample of such bulbs will be
Answer:
Hi your question is incomplete attached below is the complete question
answer : p ( X < 725 ) = 0.0116
Step-by-step explanation:
Given data:
Average life of bulbs (μ ) = 750 hours
standard deviation (б ) = 55 hours
n ( sample size ) = 25
X = 725
Probability that the mean life of a random sample of 25 bulbs will be less than725 hours
p ( X < 725 ) = p (( X - μ )/ б √n < 725 - 750 / 55√25 )
= P ( Z > - 2.27 )
Hence P ( X < 725 ) = 0.0116 ( using Z-table )

Question 3 (2 points)
(09.06)
For two functions, m(x) and p(x), a statement is made that m(x) = p(x) at x = 7. What is definitely true about x = 7? (2 points)
a
Both m(x) and p(x) cross the x-axis at 7.
b
Both m(x) and p(x) cross the y-axis at 7.
c
Both m(x) and p(x) have the same output value at x = 7.
d
Both m(x) and p(x) have a maximum or minimum value at x = 7.
9514 1404 393
Answer:
c. Both m(x) and p(x) have the same output value at x = 7.
Step-by-step explanation:
For input value x, m(x) is the output value.
m(7) is the output value of the function m(x) when x=7.
p(7) is the output value of the function p(x) when x=7.
The statement m(x) = p(x) for x=7 is a statement that the output values are the same at x=7.
