Answer:
x=2 x=8
Step-by-step explanation:
h(x)=-x^2+10x-16
Set this equal to 0
0=-x^2+10x-16
Divide by -1
0/-1=x^2-10x+16
0=x^2-10x+16
Factor
What two numbers multiply to 16 and add to -10
-2*-8 = 16
-2+-8 = -10
0=(x-2) (x-8)
Using the zero product property
x-2=0 x-8=0
x=2 x=8
These are the x intercepts
Answer:
students.
Step-by-step explanation:
We have been given that of the students that attended Roosevelt Elementary 6/8 of the school play a sport. Of the students are playing a sport 3/5 of the students are also involved in the drama club.
To find the students are both play a sport and a part of the drama club, we need to find 3/5 part of 6/8 as:
Therefore, students play sport and part of the drama club.
Answer:
<em>2j+7</em>
Step-by-step explanation:
<u>Phrase Into Algebraic Expression</u>
If a problem is correctly phrased, it should be easily translated into algebraic language by following simple and concrete rules.
We have the phrase:
<em>7 more than twice Jose's height.</em>
Usually, we first deal with products and divisions before sums and subtractions because of the natural order of mathematic operations.
In the given phrase, the '7 more' part is left to the end and we start with the 'twice' part because it's a product.
Since we are using the variable j for Jose's height, then twice Jose's height is 2j.
Now we finish the expression by adding 7: 2j+7
Thus, the translation to algebraic expression is: 2j+7
