Answer:
30 i think
Step-by-step explanation:
Answer: A. one real solution
This solution is a double root (it repeats itself). An example would be x^2-8x+16 = 0 has the only solution x = 4.
Answer:
Malcom's family travel 15 miles per hour faster than Theo's
Step-by-step explanation:
<em>See attachment for complete question</em>
Given
Malcom's Family:

To determine the equation of Theo's family, we refer to the attached graph.
From the graph:


First, we determine the slope, m:




Next, we determine equation for Theo's family using:



Add 50 to both sides


So, we have the following:
--- For Malcom's family
This implies that Malcom's family travel at 65 miles per hour
--- For Theo's family
This implies that Theo's family travel at 50 miles per hour
The difference between this rates is:


<em>Which implies that Malcom's family travel 15 miles per hour faster than Theo's</em>

y=19
Step-by-step explanation:
y=3(8)-5
y=19
The value of x is 28 millimeters in the composite figure of two right-angled triangles lying next to each other
<h3>What is a composite figure?</h3>
A composite figure is a figure that is produced from the combination of two geometric shapes together.
The diagrammatic expression of a composite figure consists of two right-angled triangles lying next to each other can be seen in the image attached below.
For the left-side right-angled triangle, we have:
13² = h² + 5²
h² = 13² - 5²
h = √(169-25)
h = 12
Recall from the diagram that:
h² = pq
∴
12² = 5x
x = 144/5
x ≅ 28 millimeters
