Answers
Answer:
infinitely many solutions
Step-by-step explanation:
make both equations equal to y
so for the first one subtract 2x from both sides getting -y=-2x-1 and then multiply the entire equation by -1 and you end up with y=2x+1
and for the second one subtract 4x from both sides getting -2y=-4x-2, multiply the entire equation by -1 which gets you 2y=2x+2 and then divide the whole equation by 2 which brings you to y=2x+1
then getting rid of y and making them equal to each other gets 2x+1=2x+1 and therefore the answer is infinitely many solutions

Note the rules of multiply/dividing negative numbers:
1) A positive number multiplied/divided by a positive number = a positive answer.
2) A positive number multiplied/divided by a negative number (and vice versa) = a negative answer.
3) A negative number multiplied/divided by a negative number = a positive answer.

Jason has 34 raspberry scones and 51 blackberry scones. He wants to make as many identical bags of scones as possible. Each bag should have an equal number of raspberry scones and an equal number of blackberry scones. What is the greatest number of bags Jason can fill? Explain how you know.
Answers
Answer: The greatest number of bags Jason can fill = 17
Step-by-step explanation:
Given: Jason has 34 raspberry scones and 51 blackberry scones.
To make identical bags of scones as possible.
Each bag should have an equal number of raspberry scones and an equal number of blackberry scones.
The greatest number of bags Jason can fill = Greatest common divisor of 3
and 51.
= 17 [Since 34 = 2 x 17 , 51 = 3 x 17]
Hence, the greatest number of bags Jason can fill = 17
The drawing below represents a 22-foot ladder with its base placed 10 feet from the bottom of a vertical wall.
which value is the best estimate for x?
a.24.3
b.63.0
c.27.0
d.65.6
Answers
Answer:
63°
Step-by-step explanation:
To get the value of x we will use the Pythagoras theorem
hyp² = opp²+adj²
Given
hyp is the length of the ladder = 22ft
Adjacent is the distance from the base of the ladder to the wall = 10ft
Angle of elevation = x
Using the SOH CAH TOA identity
Cos theta = adjacent/hypotenuse
Cos x = 10/22
Cos x = 5/11
x = arccos(5/11)
x = arccos(0.4545)
x = 62.96°
Hence the best estimate of x is 63°
Ramona is counting the posts between mile markers on the highway. In 1 mile, she counts 33 posts. If the posts are evenly spaced, how many feet apart are they? (1 mile = 5,280 feet)
Answers
Answer:
160 feet
Step-by-step explanation:
In order to solve this, we need to realize that the mile is being divided into 33 equal parts. Therefore our operation should look like this:
5,280 (the number of feet in 1 mile) / 33
5,280/33=160
The posts are 160 feet apart from each other.

Which is the graph of the system of inequalities
Answers
Answer:
A
Step-by-step explanation:
Try testing each graph by picking a point on the shaded region or none shaded region.
-1/5 and 6= y-intercept
4/5 and 2= slope
You may notice that it is in y-intercept form. So to find where the shaded region goes, test a coordinate and apply it to the equation, if the answer is false, than half of the line is not where the shaded region goes.

Which of the following graphs represents the equation y- 4 = 3(x - 1)?
A. Graph A
B. Graph B
C. Graph C
D. Graph D
Answers
The graph of the equation is graph (D)
The equation of the graph is given as:
[tex]y- 4 = 3(x - 1)[/tex]
Add 4 to both sides of the equation
[tex]y = 3(x - 1) + 4[/tex]
Apply the distributive property
[tex]y = 3x - 3+ 4[/tex]
Evaluate the sum of -3 and 4
[tex]y = 3x +1[/tex]
The above means that, the graph of [tex]y- 4 = 3(x - 1)[/tex] has a slope of 3 and a y-intercept of 1
Hence, the graph of the equation is graph (D)
