The values of H(-7)=3, H(-2)=3, H(3)=5, H(9)=11 using the given equations by substituting the values.
What is equation?The definition of an equation in algebra is a mathematical statement that demonstrates the equality of two mathematical expressions. For instance, the equation 3x + 5 = 14 consists of the two expressions 3x + 5 and 14, which are separated by the 'equal' sign. A mathematical statement known as an equation is made up of two expressions joined together by the equal sign. a formula that expresses the connection between two expressions on either side of a sign. Typically, it has a single variable and an equal sign.
Here,
H(x)= {-5x-13 for x<-7
3 for -7<=x< 3
x+2 for x=> 3}
when x=-7,
H(x)=3
when x=-2,
H(x)=3
when x=3,
H(x)=x+2
H(x)=5
when x=9,
H(x)=x+2
H(x)=11
H(-7)=3, H(-2)=3, H(3)=5, H(9)=11 when the values are substituted under the conditions stated for the given equation.

A delivery truck is transporting boxes of two sizes: large and small. The combined weight of a large box and a small box is 70 pounds. The truck is transporting 50 large boxes and 70 small boxes. If the truck is carrying a total of 4000 pounds in boxes, how much does each type of box weigh?
The weight of each small box is 25 pounds while the weight of each large box is 45 pounds
What is the weight of each type of box?We know that we can be able to find the mass of each type of box from the use of simultaneous equations. Al we need to do is to form two systems of equations. Let the weight of each small box be x and the weight of each large box be y then;
x + y = 70 ------ (1)
50x + 70y = 4000 ----- (2)
x = 70 - y ------ (3)
Substitute equation (3) into (2)
Then;
50(70 - y) + 70y = 4000
3500 - 50y + 70y = 4000
20y = 4000 - 3500
20 y = 500
y= 25
Then substitute y = 25 into equation (1)
x + 25 = 70
x = 70 - 25

What is meant by an angle?An angle is a figure in Euclidean geometry made up of two rays that share an endpoint and are referred to as the angle's sides and vertex, respectively. Angles created by two rays are located in the plane where the rays are located. The meeting of two planes can also create an angle. Dihedral angles are what they are. A measure of an angle or of a rotation is also referred to as an angle. The ratio of a circular arc's length to radius is known as this quantity. A geometric angle's arc is centered at the vertex and is bound by its sides.
For the first image x and y values are,
As from the given figure,
(4y-2)⁰=90⁰
4y=90+2

Jacob and his buddies paid $35.01 at a football game to buy 9 cheeseburger meals. How much did each cheeseburger meal cost?
I need help with this please help me
Answer:
3, 4, 5
Step-by-step explanation:
You have parallel lines crossed by a transversal, and one obtuse angle marked as 99°. You want the angle designators of the congruent angles.
Congruent anglesWhere a transversal crosses parallel lines, corresponding angles are congruent. In this figure, angle 3 corresponds to the one marked 99°, so it is congruent.
Anywhere that lines cross, vertical angles are congruent. Angles 3 and 4 are vertical angles, as are angle 5 and the one marked 99°.
Hence angles 3, 4, 5 are all congruent to the one marked 99°.
__
Additional comment
You may have observed that the listed congruent angles are all of the obtuse angles in the figure. Similarly, all acute angles in the figure are congruent. Since the acute and obtuse angles are supplementary (form linear pairs), angles 1, 2, 6, 7 are all 81°.

Step-by-step explanation:
Then finding the coordinates of the corresponding point (0.5, 0.866) on the unit circle.
The value of cos 60° is equal to the x-coordinate (0.5).
∴ cos 60° = 0.5.
The value of cos 60° using trigonometric ratio is 1/2 or 0.5 .
What is trigonometric ratios?
There are six trigonometric ratios used in trigonometry: sine, cosine, tangent, secant, and cotangent. The abbreviations for these ratios are sin, cos, tan, sec, cosec(or csc), and cot. Look at the below-displayed right-angled triangle. Any two of the three sides of a right-angled triangle can be compared in terms of their relative angles using trigonometric ratios.
