4x + y = 7
- x - y = 2
If (x, y) is the solution to the given system of equations, what
is the value of x?
a) -8
b) 26
c) -5
d) 3
Does the graph shown below represent y as a linear function of x?
Answer:
No, it does not.
Step-by-step explanation:
A linear function of x will form a straight (non-vertical) line on a graph.
This is caused directly by the equation
y = ax + b
For some constant a and b, which means that the rate of change is constant.

Show result
Please help
Answer:
x =-16
Step-by-step explanation:
Given the equation
-3x - 21 = 27
We are to find the next step in solving the equation
Step 1: Add 21 to both sides
-3x - 21 + 21 = 27 + 21
-3x = 48
Step 2: Divide both sides by -3
-3x/3 = 48/3
-x = 16
x = -16
Hence the value of x is -16
A mother is now 2 1/2 times old as her daughter Mary. Four years ago the ratio of their ages was 3:1. Find the present age of the mother.
Answer:
The present age of the mother is 40 years
Step-by-step explanation:
Let the age of the mother be M and that of the daughter D. Given that the mother is now 2 1/2 times old as her daughter Mary then
M = 2.5D
Given that Four years ago the ratio of their ages was 3:1
The mother's age 4 years ago was
= M - 4
and that of the daughter then was
= D - 4
Hence
(M - 4)/(D - 4) = 3/1
Cross multiply
M - 4 = 3(D - 4)
M - 4 = 3D - 12
M = 3D - 12 + 4
M = 3D - 8
Substitute into the first equation
3D - 8 = 2.5D
3D -2.5D = 8
0.5D = 8
D = 8/0.5
= 16 Years
M = 2.5D
M = 2.5 * 16
= 40 Years

(NEED DONE SOON) The measure of two supplementary angles are 4x - 24 and 4(2x - 3).
What is x
Answer:
X=18
Step-by-step explanation:
since angles are supplementary that means their sum is 180
[tex]4x - 24 + 4(2x - 3) = 180 \\ 4x - 24 + 8x - 12 = 180 \\ 12x - 36 = 180 \\ 12x = 216 \\ x = 18[/tex]

In AGHI, h = 300 inches, G=30° and H=29º. Find the length of i, to the nearest
inch.
Given:
In triangle GHI, h = 300 inches, G=30° and H=29º.
To find:
The length of i.
Solution:
We have, G=30° and H=29º.
Using angle sum property, we get
[tex]m\angle G+m\angle H+m\angle I=180^\circ[/tex]
[tex]30^\circ+29^\circ+m\angle I=180^\circ[/tex]
[tex]59^\circ+m\angle I=180^\circ[/tex]
[tex]m\angle I=180^\circ-59^\circ[/tex]
[tex]m\angle I=121^\circ[/tex]
According to Law of sines,
[tex]\dfrac{a}{\sin A}=\dfrac{b}{\sin B}=\dfrac{c}{\sin C}[/tex]
Using Law of sines, we get
[tex]\dfrac{h}{\sin H}=\dfrac{i}{\sin I}[/tex]
[tex]\dfrac{300}{\sin 29^\circ}=\dfrac{i}{\sin 121^\circ}[/tex]
[tex]\dfrac{300}{0.4848}=\dfrac{i}{0.8572}[/tex]
Multiply both sides by 0.8572.
[tex]\dfrac{300}{0.4848}\times 0.8572=i[/tex]
[tex]530.44554=i[/tex]
[tex]i\approx 530[/tex]
Therefore, the length of i is about 530 inches.

Please help me find the missing side and show your work
Answer:
9 yards
Step-by-step explanation:
The Pythagorean theorem: [tex]a^2+b^2=c^2[/tex]
Where a and b are legs, and c is the hypotenuse.
The hypotenuse is the side opposite from the right angle in the right triangle.
The hypotenuse would be AC, measured 15 yards, because it is opposite from the right angle. BC, the unmeasured side would be a leg. I can call that the "b" leg and AB, the 12 yard side the "a" leg.
Substitute the measures into the theorem to get: [tex]12^2+?^2=15^2[/tex]
[tex]144+?^2=225 ; ?^2=81; ?=\sqrt{81} =9[/tex]
can't find probability
Answer: [tex]0.0756,\ 0.7599[/tex]
Step-by-step explanation:
Given
Probability that a coin will land head is [tex]0.3[/tex] i.e. probability of success is [tex]p=0.3[/tex] So, the probability of failure is [tex]q=1-0.3=0.7[/tex]
Using Binomial distribution for [tex]n=4[/tex]
(a) Probability that the coin will lead heads exactly 3 times
[tex]\Rightarrow P(3)=^4C_3(0.3)^3(0.7)^1\\\Rightarrow P(3)=4\times 0.7\times (0.3)^3\\\Rightarrow P(3)=0.0756[/tex]
(b)Probability that the coin lands head at least once
[tex]\Rightarrow 1-P(0)\\\Rightarrow 1-^4C_0(0.3)^0(0.7)^4\\\Rightarrow 1-1\cdot(0.7)^4\\\Rightarrow 0.7599[/tex]

The coordinates of A are (1/4,3). The coordinates of B are (1/2,4.5). If the x-coordinate of C is 7/4, what is its y-coordinate
Answer:
10.5
Step-by-step explanation:
Given
A = (1/4, 3)
B = (1/2, 4.5)
To get the coordinate of C as 7/4, what was done was to first take the difference in the x coordinates and then dilate the result by 7
To get the y coordinate;
Take the difference in the coordinateDifference = 3 - 4.5
Difference = -1.5
Dilate the result by factor of 7This is done y multiplying the result by 7;
y coordinate = 1.5 * 7
y coordinate = 10.5
Hence its y-coordinate is 10.5
