90 per cent of the blend is watermelon juice.
Given that, Isabella has a dozen apples of the same size and a dozen watermelons of the same size.
Isabella uses her juicer to extract 15 ounces of watermelon juice from 3 watermelons and 5 ounces of apple juice from 9 apples.
We need to find what per cent of the blend is watermelon juice.
What is per cent?The percentage is a relative value indicating the hundredth part of any quantity. One per cent (symbolized 1%) is the hundredth part; thus, 100 per cent represents the entirety and 200 per cent specifies twice the given quantity.
Given that, she makes a watermelon-apple juice blend from an equal number of watermelons and apples.
So if she takes 9 apples, she can extract 5 ounces of juice.
By taking the same number of watermelons, that is 9 she can extract 15×3=45 ounces of juice.
Per cent of watermelon juice in the blend=45/50 ×100= 90%
Therefore, 90 per cent of the blend is watermelon juice.

Answer:
(5,18) & (-5 , 38)
Step-by-step explanation:
Solutions of linear and quadratic system of equations:A linear equation represented by a line in a graph intersect the quadratic equation represented by a parabola zero, one or two times.
f(x) = x² - 2x + 3 -------------------(I)
f(x) = -2x + 28 ---------------------(II)
x² - 2x + 3 = -2x + 28
x² - 2x + 2x + 3 - 28 = 0
x² - 25 = 0
x² = 25
x = √25 = √5*5
x = ± 5
Plugin x = 5 in equation (II),
f(5) = -2*5 + 28
= -10 + 28
= 18
(5 , 18)
Plugin x = -5 in equation (II),
f(-5) = -2*(-5) + 28
= 10 + 28
= 38
(-5, 38)
Answer:
(5, 18) and (-5, 38)
Step-by-step explanation:
Given system of equations:
1) f(x) = x² - 2x + 3 ⇒ y = x² - 2x + 3
2) f(x) = -2x + 28 ⇒ y = -2x + 28
Solve using the Substitution Method:
Step 1: Substitute the the first equation into the second equation.
⇒ x² - 2x + 3 = -2x + 28
Step 2: Solve for x.
x² - 2x + 3 = -2x + 28 [ Add 2x to both sides. ]
x² - 2x + 2x + 3 = -2x + 2x + 28
⇒ x² + 3 = 28 [ Subtract 28 from both sides. ]
x² + 3 - 28 = 28 - 28
⇒ x² - 25 = 0 [ Factor using the following rule: a² - b² = (a - b)(a + b). ]
(x - 5)(x + 5) = 0
⇒ x - 5 = 0, x + 5 = 0 [ Solve for the values of x. ]
x - 5 + 5 = 0 + 5, x + 5 - 5 = 0 - 5
⇒ x = 5, x = -5
Step 3: Solve for y.
Substitute the found x-values into one of the given equations.
y = x² - 2x + 3 ⇒ y = (5)² - 2(5) + 3 ⇒ y = 25 - 10 + 3 ⇒ y = 18
y = x² - 2x + 3 ⇒ y = (-5)² - 2(-5) + 3 ⇒ y = 25 + 10 + 3 ⇒ y = 38
The solutions to the system of equations are:
⟹ x₁ = 5, y₁ = 18 ⇒ (5, 18)
⟹ x₂ = -5, y₂ = 38 ⇒ (-5, 38)

Subdivide the interval [0, 3] into 6 subintervals of equal length, ∆x = (3 - 0)/6 = 1/2. Then the partition is
[tex]\left[0,\dfrac12\right] \cup \left[\dfrac12,1\right] \cup \left[1,\dfrac32\right] \cup \cdots \cup \left[\dfrac52,3\right][/tex]
The right endpoint of the [tex]i[/tex]-th subinterval is
[tex]r_i = \dfrac12 + (i-1)\times\dfrac12 = \dfrac i2[/tex]
with [tex]i\in\{1,2,3,\ldots,6\}[/tex].
Then the area under the [tex]y=x^2[/tex] on the interval [0, 3] is approximately
[tex]\displaystyle \int_0^3 x^2 \, dx \approx \sum_{i=1}^6 (r_i)^2 \Delta x = \frac18 \sum_{i=1}^6 i^2[/tex]
Recall that
[tex]\displaystyle \sum_{n=1}^N n^2 = \frac{N(N+1)(2N+1)}6[/tex]
Then the approximate value of the area is
[tex]\displaystyle \int_0^3 x^2 \, dx \approx \frac{6\times7\times13}{48} = \boxed{\frac{91}8}[/tex]
The actual value of the area is 9, so this approximation is an overestimation, as is always the case when using a right endpoint sum for an increasing function.

Using the slope-intercept form, let's identify the other slopes:

Option B:

Solve for 'x' in the following equation, explaining each step.
3^ (-3x+7) = 3^ (7x-13)
Answer:
x = 2
Step-by-step explanation:
In order to have the two sides of the equation be equal, the exponents must equal.
-3x + 7 = 7x - 13
Add 3x to both sides.
7 = 10x - 13
Add 13 to both sides.
20 = 10x
Divide by 10.
