14. A system of equations is shown below. For what value of a will this system have no solutions? Justify your answer.
y = 4x-9
y = ax+6
Answer:
a = 4
Step-by-step explanation:
a = 4
If a = 4, then both lines have the same slope and different y-intercepts. That makes both lines parallel. Since the lines never intersect, there is no solution.
Answer:
x can not equal zero, as it would cause division by zero.
Step-by-step explanation:
First, let's make one equation out of them and see what we get. Because both of them have y on the left, we can say that the two right sides are equal, giving us:
4x - 9 = ax + 6
If we solve for a, we get:
ax + 6 = 4x - 9
ax = 4x - 15
a = 4 - 15 / x
With that arrangement we can see clearly that x can not be equal to zero, as it would give us division by zero.

Solve the equation -25p – 2 = 48 for p.
A. -2
B. 1
C. 3
D. 8
Answer:
A. -2
Step-by-step explanation:
-25p - 2 = 48
First, add 2 to both sides
That gives you
-25p = 50
Then, divide both sides by -25. Then that leaves the answer.. p = -2
According to the diagram below, which similarity statements are true?
Check all that apply.
P
S
R
A. APQR - APRS
B. APQR ~ APSQ
O C. APQR ~ AQSR
D. APQS ~ AQRS
The required triangle PQS and triangle QRS are similar triangles. Option D is correct.
What are Similar triangles?Similar triangles are those triangles that have similar properties,i.e. angles and proportionality of sides.
According to the diagram,
It can be inferred that triangle PQS and triangle QRS are similar to each other. The term "similar" implies that these two triangles have the same shape but can be different in size. Specifically, the corresponding angles of these triangles are equal, and the corresponding sides are in proportion.
Consider triangle, PQS, and triangle QRS
Angle S is the common angle in both the triangles
And angle Q is similar to angle R
So both the triangle are similar by AA similarity postulate
Therefore, option D is correct.

6 pounds=x ounces
So we use the X to signal it's presence
1x16 is 16,
That means 16 ounces
6xP=Q
6x16 will give us our answer
Because it will tell us how many pounds there are since ounces is multiplied to get ounces.
6x16=96
P=16
Q=96

The equation has three solutions:
x= [tex]\frac{1}{2} + \frac{1}{2} log_{2} (3)[/tex]
x=1
x = [tex]\frac{1}{2}[/tex]
Step-by-step explanation:
||[tex]4^{x} - 3[/tex]|[tex]-2[/tex]| = 1
|[tex]4^{x} - 3[/tex]|[tex]-2[/tex] = 1 |[tex]4^{x} - 3[/tex]|[tex]-2[/tex] = - 1
|[tex]4^{x} - 3[/tex]| = 1+2 |[tex]4^{x} - 3[/tex]| = -1+2
|[tex]4^{x} - 3[/tex]|=3 |[tex]4^{x} - 3[/tex]| = 1
[tex]4^{x} - 3[/tex] =3 [tex]4^{x} - 3[/tex] = - 3 [tex]4^{x} - 3[/tex] = 1 [tex]4^{x} - 3[/tex] = - 1

A group of friends are at a baseball game and are purchasing souvenirs. Olivia purchased 1 t-shirt and 5 baseball caps, spending a total of $165. Her Marco purchased 1 t-shirt and 4 baseball caps, which cost him a total of $137. Assuming that all of the t-shirts and all of the caps are the same price, what is the price of each?
Answer:
baseball cap = $28
t-shirt = $25
Step-by-step explanation:
Olivia: t +5b = 165
Marco: t + 4b = 137
isolate t in Olivia's equation
t = 165 - 5b
plug t into Marco's equation
165 - 5b + 4b = 137
165 - b = 137
b = 28
plug b into either equation
t + 4b = 137
t + 4(28) = 137
t + 112 = 137
t = 25

Slopes of perpendicular lines are negative-reciprocals.If m is the slope of one line, the slope of the perpendicular line is -1/m.Let's find the slope of the given line:
x - 4y = -12Rewrite this in the slope-intercept form: y = mx + b
x - 4y = -124y = x + 12y = 1/4x + 3The slope is 1/4
