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.

105 calories in bananas. 75 calories in apples. If Mary only eats these fruits and her total calorie intake is 1215 how many of each fruit did she eat
Answer:
3 bananas and 12 apples.
Step-by-step explanation:
105b+ 75a = 1215 where b is number of bananas and a is number of apples.
Divide each number by 15:
7b + 5a = 81
5a must end in 5 or 10 so 7b must end in 1 or 6.
So we try:
21 and 60:
7 * 3 + 5 *1 2 = 81
So b = 3 and a = 12.
The solution is
The number of bananas is = 3 bananas
The number of apples is = 12 apples
What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the number of apples be = a
Let the number of bananas be = b
Now , the equation will be
The number of calories in bananas = 105 calories
The number of calories in apples = 75 calories
The total calories Mary takes = 1215 calories
So ,
Total calories Mary takes = number of apples x number of calories in apples + number of bananas x number of calories in bananas
Substituting the values in the equation , we get
75a + 105b = 1215
Divide by 15 on both sides of the equation , we get
5a + 7b = 81
So , substituting the values of a = 12 and b = 3 , we get
5 ( 12 ) + 7 ( 3 ) = 81
60 + 21 = 81
81 = 81
Therefore , the vale of a is 12 and value of b is 3
Hence ,
The number of bananas is 3 bananas
The number of apples is 12 apples

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.

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
