Solve the system of linear equations by elimination.
8x-5y=11
4x-3x=5
Answer:
x=5
y=-5.8
Step-by-step explanation:
4x-3x=1x
1x=5
x=5
8(5)-5y=11
40-5y=11
40-11=29
-5y=29
29/-5=-5.8
y=-5.8
At the zoo, Peter saw 9 animals. Some are kangaroos and some are
elephants. There are 30 legs in all. How many of each animal are there?
Answer:
6 elephants and 3 kangaroos in the zoo.
Step-by-step explanation:
Number of animals = 9
Number of legs seen = 30
But an elephant has 4 legs, while a kangaroo has 2 legs.
Let the number of elephant be represented by E, and the number of kangaroo by K.
So that,
E + K = 9 .................. 1
4E + 2K = 30 ............. 2
Multiply equation 1 by 2 to have
2E + 2K = 18 ............ 3
Subtract equation 3 from 1
2E = 12
E = 6
Substitute the value of E in equation 1
E + K = 9
6 + K = 9
k = 3
Thus, there were 6 elephants and 3 kangaroos in the zoo.

Answer:
The second line cuts the x-axis at x = -5/2.
Step-by-step explanation:
The given line:
[tex]3x-2y=12[/tex]
Intersects a second line at x = 2.
This second line is perpendicular to the first.
And we want to find the second line's x-intercept.
First, rearrange the first line into slope intercept form:
[tex]-2y=-3x+12[/tex]
So:
[tex]\displaystyle y=\frac{3}{2}x-6[/tex]
We can see that the slope of the first line is 3/2.
It intersects the second line at x = 2.
So, the y-value of both the first and second line at x = 2 is the same.
Find the y-value by using the first line:
[tex]\displaystyle y=\frac{3}{2}(2)-6=3-6=-3[/tex]
So, a point on both lines is (2, -3).
Since the second line is perpendicular to the first, its slope it the first's negative reciprocal.
The negative reciprocal of 3/2 is -2/3.
So, the slope of the second line is -2/3.
And we determined that it passes through (2, -3).
Then by the point-slope form:
[tex]y-y_1=m(x-x_1)[/tex]
Substitute:
[tex]\displaystyle y-(-3)=-\frac{2}{3}(x-2)[/tex]
Distribute:
[tex]\displaystyle y+3=-\frac{2}{3}x+\frac{4}{3}[/tex]
So:
[tex]\displaystyle y=-\frac{2}{3}x-\frac{5}{3}[/tex]
The second line will cut the x-axis when y = 0.
So:
[tex]\displaystyle 0 =-\frac{2}{3}x-\frac{5}{3}[/tex]
Multiply both sides by -3:
[tex]0=2x+5[/tex]
Solve for x:
[tex]\displaystyle x=-\frac{5}{2}[/tex]
The second line cuts the x-axis at x = -5/2.
Find the measure of each angle indicated. Round to the nearest tenth.
Answer:
theta = 22.6 degrees
Step-by-step explanation:
Here, we want to find the value of theta
To do this , we use the appropriate trigonometric identity
Let us identify the given sides of the triangle
we have the hypotenuse, which is the longest side of the triangle, given as 13 and the third side called the adjacent, given as 12
The trigonometric identity that relates the hypotenuse to the adjacent is the cosine
Mathematically;
cosine of an angle is the ratio of the adjacent to the hypotenuse
Thus, we have it that;
cos theta = 12/13
theta = arc(cos) 12/13
theta= 22.6

Which fraction is equivalent to -3/2
Answer:
Any fraction that will reduce to -3/2 will be equivalent to -3/2.
Examples:
-6/4
-24/16
Answer:
-6/4
Step-by-step explanation:
You can just multiply them by any factor. Remeber that what you do to the bottom you do to the top.
So,
-3/2 x 2
-6/4 (this is a fraction equivalent to it.

Answer:
square and what does the picture look like
Step-by-step explanation:
The volume of the rectangular prism to the left is represented by the equation V = x ^ 4 + 11x ^ 3 + 34x ^ 2 + 5x - 75 Using what you know about these shapes, whose volumes are calculated using the formula V = lwh find the expression that represents the height (h). Length = x+5, Width = x+3
Answer:
[tex]h = x^2+3x-5[/tex]
Step-by-step explanation:
Given
[tex]V = x^4 + 11x^3 + 34x^2 + 5x - 75[/tex]
[tex]L = x + 5[/tex]
[tex]W = x + 3[/tex]
Required
Determine the height (h) of the prism
Volume is calculated as:
[tex]V =lwh[/tex]
Substitute values for V, l and w
[tex]x^4 + 11x^3 + 34x^2 + 5x - 75 = (x + 5) * (x + 3) * h[/tex]
Factorize the expression on the left-hand side
[tex](x+3)(x^3+8x^2+10x-25)= (x + 5) * (x + 3) * h[/tex]
Further, factorize:
[tex](x+3)(x+5)(x^2+3x-5)= (x + 5) * (x + 3) * h[/tex]
Divide both sides by (x+3)(x+5)
[tex]\frac{(x+3)(x+5)(x^2+3x-5)}{(x+3)(x+5)}= \frac{(x + 5) * (x + 3) * h}{(x+3)(x+5)}[/tex]
[tex]\frac{(x+3)(x+5)(x^2+3x-5)}{(x+3)(x+5)}= h[/tex]
[tex](x^2+3x-5)= h[/tex]
[tex]x^2+3x-5= h[/tex]
[tex]h = x^2+3x-5[/tex]
The height of the prism is [tex]x^2+3x-5[/tex]
