Answer:
-2
Step-by-step explanation:
replace x with -4 in the h(x) function
h(x) = -2x-10 ➡ h(-4) = (-2)×(-4)-10 ➡8-10 = -2
Answer:
a)1 cup of flour
b)67.5 minutes
Step-by-step explanation:
a) A recipe requires 3 cups of flour to make 27 dinner rolls. How much flour is needed to make 9 rolls?
From the above question, we know that:
27 dinner rolls = 3 cups of flour
9 dinner rolls = x
Cross Multiply
27 rolls × x = 9 rolls × 3 cups
x = 9 rolls × 3 cups/27 rolls
x = 1 cup of flour
Hence, 1 cup of flour is needed to make 9 dinner rolls
b) Mandy runs 4 km in 18 min. She plans to run in a 15 km race. How long will it take her to complete the race?
From the above question:
4 km = 18 minutes
15km = x
Cross Multiply
4km × x = 15km × 18 minutes
x = 15km × 18minutes/4km
x = 67.5 minutes
Hence, in a 15km race , it would take her 67.5 minutes to complete her race.
Answer: y=
+2
Step-by-step explanation:
<em>This is y intercept form</em>
First you find the slope
Then you find the y intercept and plug it in t the equation y=mx+b
£36.48.
1. Multiply 38 by 0.04 (4% in decimal) and you’ll get 1.52
2. Subtract 1.52 from 38 to get 36.48
