Need help with this. Write an equation that is parallel to the line whose equation is y = −8x − 7?
An equation of the line that has a slope of 3
and a y-intercept of -2 is
Answers
Answer:
Problem 4: y = -8x+b
Problem 5: C: 3x-2
Step-by-step explanation:
Problem 4:
The given line is in slope intercept form.
The slope-intercept form is:
[tex]y = mx+b[/tex]
Here the co-efficient of x is the slope of the line. Comparing the given equation with general form
m = -8
Two parallel lines have same slope so the slope of line will be -8.
[tex]y=mx+b\\y = -8x+b[/tex]
b can be any positive or negative integer as we don't know any point on the line parallel to given line.
Problem 5:
Slope = 3
y-intercept = -2
Slope intercept of line is given by:
[tex]y = mx+b[/tex]
here m is slope and b is y-intercept
Putting the values
[tex]y = 3x-2[/tex]
Option C: y=3x-2 is the correct answer
Hence,
Problem 4: y = -8x+b
Problem 5: C: 3x-2

Find (f-g) (x)
Answers
Answer:
After solving we get [tex]\mathbf{(f-g)(x)=-4x^3+7x^2+5x-8}[/tex]
Option A is correct option.
Step-by-step explanation:
We are given :
[tex]f(x) = 4x^2 +5x -3\\g(x)= 4x^3 - 3x^2 +5[/tex]
We need to find (f-g)(x)
(f-g)(x) is equal to f(x)-g(x)
So, finding (f-g)(x)
[tex](f-g)(x)=f(x)-g(x)\\(f-g)(x)=4x^2+5x-3-(4x^3-3x^2+5)\\(f-g)(x)=4x^2+5x-3-4x^3+3x^2-5\\Combining \ like \ terms:\\(f-g)(x)=-4x^3+3x^2+4x^2+5x-3-5\\(f-g)(x)=-4x^3+7x^2+5x-8[/tex]
So, after solving we get [tex]\mathbf{(f-g)(x)=-4x^3+7x^2+5x-8}[/tex]
Option A is correct option.
9) A basic cell phone plan at Verizon Wireless costs $45 a month with an additional $0.10 per text message sent. AT&T charges $30 a month with an additional $0.13 per text message sent. How many text messages would you have to send for the plans to cost the same? If you send an average of 1200 text messages a month, which company would you want to choose as your provider?
a. Define your variables &Write your system of equations
b. Use your equations to solve. Make sure you label your answer
Answers
Number of tests made =x
Verzon C(x) = 45 + 0.1x => 45+0.1*1200 =165
AT & T C(y) = 30 + 0.13x=> 30 + 0.13*1200=186
For 1200 texts C(x) is less than C(y)
If the costs are to be the same then
45 + 0.1x = 30 + 0.13x
15=0.03x
15/0.03= x
500=x

The smaller triangle was dilated to form the larger triangle. What is the value of x? A smaller triangle has side lengths of 5, 13, 12. A larger triangle has side lengths of x, blank, 18. 6.9 7.5 10 11
Answers
Answer:
x = 7.5
Step-by-step explanation:
Dilation is a transformation in which the size of a given figure is either increased or decreased by a scale factor.
Given that the length of sides of the smaller triangle are; 5, 13, 12.
Given also that the length of the dilated triangle are; x, blank, 18.
Comparing the length of the last sides of the two triangles, we have;
(scale factor x 12) + 12
= ([tex]\frac{1}{2}[/tex] x 12) + 12
= 6 + 12
= 18
Thus the scale factor for the dilation is [tex]\frac{1}{2}[/tex]. So that:
x = ([tex]\frac{1}{2}[/tex] x 5) + 5
= 2.5 + 5
= 7.5
x = 7.5
And also,
blank = ([tex]\frac{1}{2}[/tex] x 13) + 13
= 6.5 + 13
blank = 19.5
Therefore, the length of the sides of dilated triangle are: 7.5, 19.5, 18
Answer:
7.5

Answer:
a. 35°
b. 6 units
Step-by-step explanation:
a. By the property of intersecting tangent and secant outside of a circle, we have:
[tex] m\angle P = \frac{1} {2} \times \bigg(m\widehat{QS} - m\widehat{QR}\bigg) \\\\
m\angle P = \frac{1} {2} \times \bigg(150\degree - 80\degree\bigg) \\\\
m\angle P = \frac{1} {2} \times 70\degree \\\\
\huge\purple {\boxed{m\angle P =35\degree}} \\[/tex]
b.
[tex] PS = PR + RS = 4 + 5 = 9\: units\\[/tex]
By the property of intersecting tangent and secant outside of a circle, we have:
[tex]
PQ^2 = PR\times PS\\\\
PQ^2 = 4\times 9\\\\
PQ^2 = 36\\\\
PQ =\pm \sqrt {36} \\\\
PQ=\pm 6\\[/tex]
Since, PQ can not be a negative number.
So, PQ = 6 units.
