The answer is $6.75 for topping and for the pizza is $2.25
The drop down menus are not provided. However, I will help get the solution of the system of equation which is the requirement of the question.
<u><em>Answer:</em></u>
(3,14) and (-2,-1) are the solutions of the system
<u><em>Explanation:</em></u>
<u>The first equation given is:</u>
y = x² + 2x - 1 .........> equation I
<u>The second given equation is:</u>
y - 3x = 5
<u>This can be rewritten as:</u>
y = 3x + 5 ..........> equation II
<u>Equate equations I and II and solve for x as follows:</u>
x² + 2x - 1 = 3x + 5
x² + 2x - 1 - 3x - 5 = 0
x² - x - 6 = 0
(x-3)(x+2) = 0
either x-3 = 0 .........> x = 3
or x+2 = 0 ...........> x = -2
<u>Now, we get the values of y by substituting in equation II as follows:</u>
At x = 3:
y = 3x + 5
y = 3(3) + 5
y = 14
The first solution is (3,14)
At x = -2:
y = 3x + 5
y = 3(-2) + 5
y = -1
The second solution is (-2,-1)
Hope this helps :)
The difference between five times the number and four is one
Subtracting four from five times a number will result you to one
Answer:
C. 6 inches
Step-by-step explanation:
It is a 45, 45, 90 triangle because there is a 90 degree angle and since both of the legs are equal it is an isosceles triangle so the two angles are equal, so they can both only be 45 because together they have to equal 90.
That means the two radii are x and the hypotenuse is x√2 so √72 = x√2
√72 = x√2
now you divide both sides by √2 so that the x is alone
√72/√2 = x you have to multiply the √72/√2 by √2 because the denominator can not be a radical, You dont have to do it to the x because you are multiply both the numerator and denominator by√2 so it is like 1
√72/√2 * √2/√2
√144/√4 the √144 is 12 and the √4 is 2
12/2 now simplify
6
