Answer:
x=-79/4, y=-45/8. (-79/4, -45/8).
Step-by-step explanation:
-2x+4y=17
3x-10y=-3
---------------
3(-2x+4y)=3(17)
2(3x-10y)=2(-3)
----------------------
-6x+12y=51
6x-20y=-6
------------------
-8y=45
y=45/-8=-45/8
3x-10(-45/8)=-3
3x+450/8=-3
3x+225/4=-3
3x=-3-225/4
3x=-12/4-225/4
3x=-237/4
x=(-237/4)/3
x=(-237/4)(1/3)
x=-237/12=-79/4

What is the y-intercept
Step-by-step explanation:
To find the y intercept we need to find slope first which can be done by taking 2 points and using the slope formula
5 - 10
---------- = -5/3
12--9
The slope is -5/3 now we take one point substitute the slope in and find the y intercept
5=-12( -5/3) +b
5= 20+ b
-15 =b
The y-intercept is -15

PLZ ANSWER !!!!!!
An eagle is flying at an altitude of 280 feet. The angle of depression from the eagle to a mouse on the ground is 15º. What is the direct line distance from the eagle to the mouse? Round answer to the nearest thousandth.
Answer:
289.877 ft
Step-by-step explanation:
You can draw the eagle and mouse by using a right triangle. You know that the height of the triangle will be 280 feet and the distance between eagle and mouse should be the hypotenuse. Since we know the angle and one side of the triangle, we can use trignometry (cosine(angle)=adjacent/hypotenuse). Plug in your values and solve for the hypotenuse.

Step-by-step explanation:
You have parallel lines cut by a transversal, so alternate interior angles are congruent. Also, alternate exterior angles are congruent. Corresponding angles are congruent.
Vertical angles are always congruent.
I'll write each congruent angle and the reason.
<2, vertical
<3, corresponding
<4, alternate exterior angle

Line segment JK has endpoints at J(-3,4) and K(3,6). Which is an equation of a line that is perpendicular to line segment JK and passes through the point (3,-12)
Answer:
y = -3x - 3.
Step-by-step explanation:
Find the slope of the line JK:
Slope = (6-4)/(3- (-3))
= 2 / 6
= 1/3.
Therefore the slope of the line perpendicular to it is - 1 / 1/3
= -3.
Now we use the point-slope form of a line to get the required equation:
y - y1 = m(x - x1)
Here m = -3 and (x1, y1) = (3, -12) so we have
y - (-12) = -3(x - 3)
y + 12 = -3x + 9
y = -3x + 9 - 12
y = -3x - 3 is the answer.
what is the factor expression of 12p+30
Answer:
6(2p + 5)
Step-by-step explanation:
The largest common factor of 12 and 30 is 6. Thus,
12p+30 = 6(2p + 5)
Answer:
12x +30=6(2x+5)
Step-by-step explanation:
Find the Greatest Common Factor (GCF)
GCF = 6
Factor out the GCF (Write the GCF first and then in parenthesis, divide each term by the GCF)
6(12p/6 + 30/6)
Simplify each term that is within the parenthesis
6(2p + 5)

Given:
Base angle of an isosceles triangle is 15 degrees more than its vertical angle.
To find:
The measure of each angle of the triangle.
Solution:
Let x be the vertical angle. Then,
One base angle = x+15 degrees
We know that base angles of an isosceles triangle are equal.
Another base angle = x+15 degrees
Now, the sum of all angles of a triangle is 180 degrees by the angle sum property.
[tex]x^\circ+(x+15)^\circ+(x+15)^\circ=180^\circ[/tex] (Angle sum property)
[tex](3x+30)^\circ=180^\circ[/tex]
[tex]3x+30=180[/tex]
[tex]3x=180-30[/tex]
[tex]3x=150[/tex]
Divide both sides by 3.
[tex]x=\dfrac{150}{3}[/tex]
[tex]x=50[/tex]
The measure of base angles is
[tex](x+15)^\circ=(50+15)^\circ[/tex]
[tex](x+15)^\circ=65^\circ[/tex]
Therefore, the measure of angles are 50°, 65° and 65°.
A rectangle measures 2 1/3 inches by 1 2/3 inches. What is its area?
Answer:
35/9 inches
Step-by-step explanation:
you can put this in a mixed fraction, its still correct:
3 8/9
The area of the rectangle is 35/9 square inches.
What is a rectangle?A rectangle is a 2-D shape with length and width.
The length and width are different.
If the length and width are not different then it is a square.
The area of a rectangle is given as:
Area = Length x width
We have,
To find the area of a rectangle,
We multiply the length by the width.
Length = 2 1/3 = 7/3 inches
Width = 1 2/3 = 5/3 inches
Area = Length x Width
Area = (7/3) x (5/3)
Area = 35/9 square inches
Therefore,
The area of the rectangle is 35/9 square inches.

Answer:
Pair 1: GM and LJ
Pair 2:HI and LM
Step-by-step explanation:
The markings on the line show which lines are congruent to each other. This means that line HI and ML are congruent because they have similar markings. And you could say the same for line JL and MG because it has 2 lines that mark it as congruent to eachother.
So basically your answers are GM and LJ as one pair and HI and LM as another

What is the slope of the line
Answer:
[tex]\frac{1}{2}[/tex]
Step-by-step explanation:
When finding the slope, pick two points on the linear line.
( -1.5, -1) (0.5, 0)
-1.5 is x1
-1 is y1
0.5 is x2
0 is y2
Place these numbers in a slop formula.
m = [tex]\frac{0 - (-1)}{0.5 - (-1.5)}[/tex] = [tex]\frac{1}{2}[/tex]
(m means slope)
Slope = [tex]\frac{1}{2}[/tex]

Complete question :
Different dealers may sell the same car for different prices. The sale prices for a particular car are normally distributed with a mean and standard deviation of 26 thousand dollars and 2 thousand dollars, respectively. Suppose we select one of these cars at random. Let X represent the sale price (in thousands of dollars) for the selected car.1. Find P(26< X<30) You may round your answer to two decimal places
Answer:
0.48
Step-by-step explanation:
Mean, m = 26000 ; Standard deviation, s = 2000
P(x < x)
Zscore = (x - m) / s
P(26< X<30) ;
P[(26 - 26 / 2) < (30 - 26) / 2)]
P[(0 < Z < 2)]
P(Z < 2) - P(Z <0)
Using a z table of z calculator, we can obtain the probabilties of the Z value :
0.97725 - 0.5
= 0.47725
= 0.48 ( 2 decimal places)
