Answers
Answer:
1.9
Step-by-step explanation:
2x+7=10.8
2x=3.8
x=1.9
1.9x2=3.8+7=10.8
The required number is 1.9, when multiply by 2 and add 7 to the product gives 10.8.
What are equation models?The equation model is defined as the model of the given situation in the form of an equation using variables and constants.
Here,
let the number be x,
According to the question,
2x + 7 = 10.8
Simplifying the above expression,
2x = 10.8 - 7
2x = 3.8
x = 1.9

Which equation in slope-intercept form represents a line that passes through the point (2,3) and is
perpendicular to the line y - 9 = (0 + 7)?
Answers
Answer:
The answer is below
Step-by-step explanation:
Which equation in slope-intercept form represents a line that passes through the point (2,3) and is perpendicular to the line y−9=23(x+7)
Solution:
The equation of a line in slope intercept form is given as y = mx + b, where m is the slope and b is the y intercept.
Given a line y−9=23(x+7)
y - 9 = 23x + 161
y = 23x + 170. The slope of this line comparing with y = mx + b gives m = 23
Two lines are perpendicular if the product of their slope gives -1.
Let [tex]m_1[/tex] be the slope of the perpendicular line, hence:
[tex]m_1(23)=-1\\\\m_1=\frac{-1}{23}[/tex]
Since the perpendicular line passes through (2, 3), we can get its equation using:
[tex]y-y_1=m_1(x_x_1)\\\\y-3=\frac{-1}{23}(x-2)\\\\y= \frac{-1}{23}x+\frac{2}{23}+3\\\\ y= \frac{-1}{23}x+\frac{71}{23}[/tex]

Jorie leaves work 30 minutes late. She decides to make up time by taking the toll road instead of side streets. She can travel four times faster by taking the toll road. Create an equation to represent her total travel time, including wait time, where x is the number of minutes the drive was expected to take.
y equals one fourth times x minus thirty
y = 4x − 30
y equals one fourth times x plus thirty
y = 4x + 30
Answers
Answer:
option C
Step-by-step explanation:
We know that the toll road is 4 times faster than the side streets.If 'x' represents the number of minutes she usually spend taking the side streets. The represents the time she takes taking the toll road.Also we need to create an equation to represent her total travel time, including wait time
Given trapezoid ABCD whose bases are segment AB and segment CD, what is mZB?
Answers
Answer:
x = 19
<B = 125°
Step-by-step explanation:
The sum f angle <D and angle <A is equal to 180° because these angles are supplementary
75° + 5x + 10 = 180° add like terms
85 + 5x = 180 subtract 85 from both sides
5x = 95 divide both sides by 5
x = 19
Same rule goes for angle <C and angle <B
<B + 55° = 180 subtract 55 from both sides
<B = 125°
The ratio of dogs to cats at the SPCA is 3:2. If there are 48 cats, how many dogs are there?
Answers
Answer:
72 dogs
Step-by-step explanation:
3 dogs/2 cats = x dogs/48 cats
Cross Multiply
3/2 x x/48
2x=144
x=72
Answer:
72 dogs
Step-by-step explanation:
First turn 3:2 into a fraction:
3/2
Then you can make the equation a proportion question, which is much eaiser to handle.
3/2=x/48 (I recommend writing this out so it will be easier to see)
Then you cross multiply, or multiply by the numerator of the first fraction by the denominator of the second, and the denominator of the first fraction by the numerator of the second.
Multiply 2 by x, which becomes 2x.
Multiply 3 by 48, which is 144
This becomes... 2x=144
You then solve with equation by dividing 144/2 and getting 72.
Meaning x=72 dogs

The solution of this system of linear equations is [tex](x,y) = (-3,-2)[/tex].
Step-by-step explanation:
Let be the following system of linear equations:
[tex]2\cdot x - 7\cdot y = 8[/tex] (1)
[tex]-3\cdot x + 2\cdot y = 5[/tex] (2)
From (1) we clear [tex]y[/tex]:
[tex]2\cdot x -8 = 7\cdot y[/tex]
[tex]y = \frac{2\cdot x - 8}{7}[/tex]
And we apply this variable in (2):
[tex]-3\cdot x+2\cdot \left(\frac{2\cdot x -8}{7} \right)= 5[/tex]
[tex]-3\cdot x +\frac{4}{7} \cdot x -\frac{16}{7} = 5[/tex]
[tex]-\frac{17}{7}\cdot x = \frac{51}{7}[/tex]
[tex]x = -\frac{51}{17}[/tex]
[tex]x = -3[/tex]
And the value of [tex]y[/tex] is:
[tex]y = \frac{2\cdot (-3)-8}{7}[/tex]
[tex]y = -\frac{14}{7}[/tex]
[tex]y = -2[/tex]
The solution of this system of linear equations is [tex](x,y) = (-3,-2)[/tex].

If the given figure is rotated 180° around the origin? What are the new coordinates of point Z?
Answers
Answer:
(a,b) to (-a,-b)
Step-by-step explanation:
You can think of this as folding the paper horizontly and vertically, and see where the new point lies. You see that the x coordinate changes its sign when the paper folds vertically, and the y coordinate changes its sign when folded horizontally.
But in general, if you have point (a,b) and if you rotate it 180 degrees, you just switch the signs, and you will get (-a,-b).
Ex. (-6,5) rotates 180 degrees and becomes (6,-5)
